Taking a complexity perspective.
The first paper in this series 17 outlines aspects of complexity associated with complex interventions and health systems that can potentially be explored by different types of evidence, including synthesis of quantitative and qualitative evidence. Petticrew et al 17 distinguish between a complex interventions perspective and a complex systems perspective. A complex interventions perspective defines interventions as having “implicit conceptual boundaries, representing a flexible, but common set of practices, often linked by an explicit or implicit theory about how they work”. A complex systems perspective differs in that “ complexity arises from the relationships and interactions between a system’s agents (eg, people, or groups that interact with each other and their environment), and its context. A system perspective conceives the intervention as being part of the system, and emphasises changes and interconnections within the system itself”. Aspects of complexity associated with implementation of complex interventions in health systems that could potentially be addressed with a synthesis of quantitative and qualitative evidence are summarised in table 2 . Another paper in the series outlines criteria used in a new evidence to decision framework for making decisions about complex interventions implemented in complex systems, against which the need for quantitative and qualitative evidence can be mapped. 16 A further paper 18 that explores how context is dealt with in guidelines and reviews taking a complexity perspective also recommends using both quantitative and qualitative evidence to better understand context as a source of complexity. Mixed-method syntheses of quantitative and qualitative evidence can also help with understanding of whether there has been theory failure and or implementation failure. The Cochrane Qualitative and Implementation Methods Group provide additional guidance on exploring implementation and theory failure that can be adapted to address aspects of complexity of complex interventions when implemented in health systems. 19
Health-system complexity-related questions that a synthesis of quantitative and qualitative evidence could address (derived from Petticrew et al 17 )
Aspect of complexity of interest | Examples of potential research question(s) that a synthesis of qualitative and quantitative evidence could address | Types of studies or data that could contribute to a review of qualitative and quantitative evidence |
What ‘is’ the system? How can it be described? | What are the main influences on the health problem? How are they created and maintained? How do these influences interconnect? Where might one intervene in the system? | Quantitative: previous systematic reviews of the causes of the problem); epidemiological studies (eg, cohort studies examining risk factors of obesity); network analysis studies showing the nature of social and other systems Qualitative data: theoretical papers; policy documents |
Interactions of interventions with context and adaptation | Qualitative: (1) eg, qualitative studies; case studies Quantitative: (2) trials or other effectiveness studies from different contexts; multicentre trials, with stratified reporting of findings; other quantitative studies that provide evidence of moderating effects of context | |
System adaptivity (how does the system change?) | (How) does the system change when the intervention is introduced? Which aspects of the system are affected? Does this potentiate or dampen its effects? | Quantitative: longitudinal data; possibly historical data; effectiveness studies providing evidence of differential effects across different contexts; system modelling (eg, agent-based modelling) Qualitative: qualitative studies; case studies |
Emergent properties | What are the effects (anticipated and unanticipated) which follow from this system change? | Quantitative: prospective quantitative evaluations; retrospective studies (eg, case–control studies, surveys) may also help identify less common effects; dose–response evaluations of impacts at aggregate level in individual studies or across studies included with systematic reviews (see suggested examples) Qualitative: qualitative studies |
Positive (reinforcing) and negative (balancing) feedback loops | What explains change in the effectiveness of the intervention over time? Are the effects of an intervention are damped/suppressed by other aspects of the system (eg, contextual influences?) | Quantitative: studies of moderators of effectiveness; long-term longitudinal studies Qualitative: studies of factors that enable or inhibit implementation of interventions |
Multiple (health and non-health) outcomes | What changes in processes and outcomes follow the introduction of this system change? At what levels in the system are they experienced? | Quantitative: studies tracking change in the system over time Qualitative: studies exploring effects of the change in individuals, families, communities (including equity considerations and factors that affect engagement and participation in change) |
It may not be apparent which aspects of complexity or which elements of the complex intervention or health system can be explored in a guideline process, or whether combining qualitative and quantitative evidence in a mixed-method synthesis will be useful, until the available evidence is scoped and mapped. 17 20 A more extensive lead in phase is typically required to scope the available evidence, engage with stakeholders and to refine the review parameters and questions that can then be mapped against potential review designs and methods of synthesis. 20 At the scoping stage, it is also common to decide on a theoretical perspective 21 or undertake further work to refine a theoretical perspective. 22 This is also the stage to begin articulating the programme theory of the complex intervention that may be further developed to refine an understanding of complexity and show how the intervention is implemented in and impacts on the wider health system. 17 23 24 In practice, this process can be lengthy, iterative and fluid with multiple revisions to the review scope, often developing and adapting a logic model 17 as the available evidence becomes known and the potential to incorporate different types of review designs and syntheses of quantitative and qualitative evidence becomes better understood. 25 Further questions, propositions or hypotheses may emerge as the reviews progress and therefore the protocols generally need to be developed iteratively over time rather than a priori.
Following a scoping exercise and definition of key questions, the next step in the guideline development process is to identify existing or commission new systematic reviews to locate and summarise the best available evidence in relation to each question. For example, case study 2, ‘Optimising health worker roles for maternal and newborn health through task shifting’, included quantitative reviews that did and did not take an additional complexity perspective, and qualitative evidence syntheses that were able to explain how specific elements of complexity impacted on intervention outcomes within the wider health system. Further understanding of health system complexity was facilitated through the conduct of additional country-level case studies that contributed to an overall understanding of what worked and what happened when lay health worker interventions were implemented. See table 1 online supplementary file 2 .
There are a few existing examples, which we draw on in this paper, but integrating quantitative and qualitative evidence in a mixed-method synthesis is relatively uncommon in a guideline process. Box 2 includes a set of key questions that guideline developers and review authors contemplating combining quantitative and qualitative evidence in mixed-methods design might ask. Subsequent sections provide more information and signposting to further reading to help address these key questions.

Petticrew et al 17 define the different aspects of complexity and examples of complexity-related questions that can potentially be explored in guidelines and systematic reviews taking a complexity perspective. Relevant aspects of complexity outlined by Petticrew et al 17 are summarised in table 2 below, together with the corresponding questions that could be addressed in a synthesis combining qualitative and quantitative evidence. Importantly, the aspects of complexity and their associated concepts of interest have however yet to be translated fully in primary health research or systematic reviews. There are few known examples where selected complexity concepts have been used to analyse or reanalyse a primary intervention study. Most notable is Chandler et al 26 who specifically set out to identify and translate a set of relevant complexity theory concepts for application in health systems research. Chandler then reanalysed a trial process evaluation using selected complexity theory concepts to better understand the complex causal pathway in the health system that explains some aspects of complexity in table 2 .
Rehfeuss et al 16 also recommends upfront consideration of the WHO-INTEGRATE evidence to decision criteria when planning a guideline and formulating questions. The criteria reflect WHO norms and values and take account of a complexity perspective. The framework can be used by guideline development groups as a menu to decide which criteria to prioritise, and which study types and synthesis methods can be used to collect evidence for each criterion. Many of the criteria and their related questions can be addressed using a synthesis of quantitative and qualitative evidence: the balance of benefits and harms, human rights and sociocultural acceptability, health equity, societal implications and feasibility (see table 3 ). Similar aspects in the DECIDE framework 15 could also be addressed using synthesis of qualitative and quantitative evidence.
Integrate evidence to decision framework criteria, example questions and types of studies to potentially address these questions (derived from Rehfeuss et al 16 )
Domains of the WHO-INTEGRATE EtD framework | Examples of potential research question(s) that a synthesis of qualitative and/or quantitative evidence could address | Types of studies that could contribute to a review of qualitative and quantitative evidence |
Balance of benefits and harms | To what extent do patients/beneficiaries different health outcomes? | Qualitative: studies of views and experiences Quantitative: Questionnaire surveys |
Human rights and sociocultural acceptability | Is the intervention to patients/beneficiaries as well as to those implementing it?

Societal implications | What is the of the intervention: are there features of the intervention that increase or reduce stigma and that lead to social consequences? Does the intervention enhance or limit social goals, such as education, social cohesion and the attainment of various human rights beyond health?

Questions can serve as an ‘anchor’ by articulating the specific aspects of complexity to be explored (eg, Is successful implementation of the intervention context dependent?). 27 Anchor questions such as “How does intervention x impact on socioeconomic inequalities in health behaviour/outcome x” are the kind of health system question that requires a synthesis of both quantitative and qualitative evidence and hence a mixed-method synthesis. Quantitative evidence can quantify the difference in effect, but does not answer the question of how . The ‘how’ question can be partly answered with quantitative and qualitative evidence. For example, quantitative evidence may reveal where socioeconomic status and inequality emerges in the health system (an emergent property) by exploring questions such as “ Does patterning emerge during uptake because fewer people from certain groups come into contact with an intervention in the first place? ” or “ are people from certain backgrounds more likely to drop out, or to maintain effects beyond an intervention differently? ” Qualitative evidence may help understand the reasons behind all of these mechanisms. Alternatively, questions can act as ‘compasses’ where a question sets out a starting point from which to explore further and to potentially ask further questions or develop propositions or hypotheses to explore through a complexity perspective (eg, What factors enhance or hinder implementation?). 27 Other papers in this series provide further guidance on developing questions for qualitative evidence syntheses and guidance on question formulation. 14 28
For anchor and compass questions, additional application of a theory (eg, complexity theory) can help focus evidence synthesis and presentation to explore and explain complexity issues. 17 21 Development of a review specific logic model(s) can help to further refine an initial understanding of any complexity-related issues of interest associated with a specific intervention, and if appropriate the health system or section of the health system within which to contextualise the review question and analyse data. 17 23–25 Specific tools are available to help clarify context and complex interventions. 17 18
If a complexity perspective, and certain criteria within evidence to decision frameworks, is deemed relevant and desirable by guideline developers, it is only possible to pursue a complexity perspective if the evidence is available. Careful scoping using knowledge maps or scoping reviews will help inform development of questions that are answerable with available evidence. 20 If evidence of effect is not available, then a different approach to develop questions leading to a more general narrative understanding of what happened when complex interventions were implemented in a health system will be required (such as in case study 3—risk communication guideline). This should not mean that the original questions developed for which no evidence was found when scoping the literature were not important. An important function of creating a knowledge map is also to identify gaps to inform a future research agenda.
Table 2 and online supplementary files 1–3 outline examples of questions in the three case studies, which were all ‘COMPASS’ questions for the qualitative evidence syntheses.
The shift towards integration of qualitative and quantitative evidence in primary research has, in recent years, begun to be mirrored within research synthesis. 29–31 The natural extension to undertaking quantitative or qualitative reviews has been the development of methods for integrating qualitative and quantitative evidence within reviews, and within the guideline process using evidence to decision-frameworks. Advocating the integration of quantitative and qualitative evidence assumes a complementarity between research methodologies, and a need for both types of evidence to inform policy and practice. Below, we briefly outline the current designs for integrating qualitative and quantitative evidence within a mixed-method review or synthesis.
One of the early approaches to integrating qualitative and quantitative evidence detailed by Sandelowski et al 32 advocated three basic review designs: segregated, integrated and contingent designs, which have been further developed by Heyvaert et al 33 ( box 3 ).
Segregated design.
Conventional separate distinction between quantitative and qualitative approaches based on the assumption they are different entities and should be treated separately; can be distinguished from each other; their findings warrant separate analyses and syntheses. Ultimately, the separate synthesis results can themselves be synthesised.
The methodological differences between qualitative and quantitative studies are minimised as both are viewed as producing findings that can be readily synthesised into one another because they address the same research purposed and questions. Transformation involves either turning qualitative data into quantitative (quantitising) or quantitative findings are turned into qualitative (qualitising) to facilitate their integration.
Takes a cyclical approach to synthesis, with the findings from one synthesis informing the focus of the next synthesis, until all the research objectives have been addressed. Studies are not necessarily grouped and categorised as qualitative or quantitative.
A recent review of more than 400 systematic reviews 34 combining quantitative and qualitative evidence identified two main synthesis designs—convergent and sequential. In a convergent design, qualitative and quantitative evidence is collated and analysed in a parallel or complementary manner, whereas in a sequential synthesis, the collation and analysis of quantitative and qualitative evidence takes place in a sequence with one synthesis informing the other ( box 4 ). 6 These designs can be seen to build on the work of Sandelowski et al , 32 35 particularly in relation to the transformation of data from qualitative to quantitative (and vice versa) and the sequential synthesis design, with a cyclical approach to reviewing that evokes Sandelowski’s contingent design.
Convergent synthesis design.
Qualitative and quantitative research is collected and analysed at the same time in a parallel or complementary manner. Integration can occur at three points:
a. Data-based convergent synthesis design
All included studies are analysed using the same methods and results presented together. As only one synthesis method is used, data transformation occurs (qualitised or quantised). Usually addressed one review question.
b. Results-based convergent synthesis design
Qualitative and quantitative data are analysed and presented separately but integrated using a further synthesis method; eg, narratively, tables, matrices or reanalysing evidence. The results of both syntheses are combined in a third synthesis. Usually addresses an overall review question with subquestions.
c. Parallel-results convergent synthesis design
Qualitative and quantitative data are analysed and presented separately with integration occurring in the interpretation of results in the discussion section. Usually addresses two or more complimentary review questions.
A two-phase approach, data collection and analysis of one type of evidence (eg, qualitative), occurs after and is informed by the collection and analysis of the other type (eg, quantitative). Usually addresses an overall question with subquestions with both syntheses complementing each other.
The three case studies ( table 1 , online supplementary files 1–3 ) illustrate the diverse combination of review designs and synthesis methods that were considered the most appropriate for specific guidelines.
In this section, we draw on examples where specific review designs and methods have been or can be used to explore selected aspects of complexity in guidelines or systematic reviews. We also identify other review methods that could potentially be used to explore aspects of complexity. Of particular note, we could not find any specific examples of systematic methods to synthesise highly diverse research designs as advocated by Petticrew et al 17 and summarised in tables 2 and 3 . For example, we could not find examples of methods to synthesise qualitative studies, case studies, quantitative longitudinal data, possibly historical data, effectiveness studies providing evidence of differential effects across different contexts, and system modelling studies (eg, agent-based modelling) to explore system adaptivity.
There are different ways that quantitative and qualitative evidence can be integrated into a review and then into a guideline development process. In practice, some methods enable integration of different types of evidence in a single synthesis, while in other methods, the single systematic review may include a series of stand-alone reviews or syntheses that are then combined in a cross-study synthesis. Table 1 provides an overview of the characteristics of different review designs and methods and guidance on their applicability for a guideline process. Designs and methods that have already been used in WHO guideline development are described in part A of the table. Part B outlines a design and method that can be used in a guideline process, and part C covers those that have the potential to integrate quantitative, qualitative and mixed-method evidence in a single review design (such as meta-narrative reviews and Bayesian syntheses), but their application in a guideline context has yet to be demonstrated.
Depending on the review design (see boxes 3 and 4 ), integration can potentially take place at a review team and design level, and more commonly at several key points of the review or guideline process. The following sections outline potential points of integration and associated practical considerations when integrating quantitative and qualitative evidence in guideline development.
In a guideline process, it is common for syntheses of quantitative and qualitative evidence to be done separately by different teams and then to integrate the evidence. A practical consideration relates to the organisation, composition and expertise of the review teams and ways of working. If the quantitative and qualitative reviews are being conducted separately and then brought together by the same team members, who are equally comfortable operating within both paradigms, then a consistent approach across both paradigms becomes possible. If, however, a team is being split between the quantitative and qualitative reviews, then the strengths of specialisation can be harnessed, for example, in quality assessment or synthesis. Optimally, at least one, if not more, of the team members should be involved in both quantitative and qualitative reviews to offer the possibility of making connexions throughout the review and not simply at re-agreed junctures. This mirrors O’Cathain’s conclusion that mixed-methods primary research tends to work only when there is a principal investigator who values and is able to oversee integration. 9 10 While the above decisions have been articulated in the context of two types of evidence, variously quantitative and qualitative, they equally apply when considering how to handle studies reporting a mixed-method study design, where data are usually disaggregated into quantitative and qualitative for the purposes of synthesis (see case study 3—risk communication in humanitarian disasters).
Clearly specified key question(s), derived from a scoping or consultation exercise, will make it clear if quantitative and qualitative evidence is required in a guideline development process and which aspects will be addressed by which types of evidence. For the remaining stages of the process, as documented below, a review team faces challenges as to whether to handle each type of evidence separately, regardless of whether sequentially or in parallel, with a view to joining the two products on completion or to attempt integration throughout the review process. In each case, the underlying choice is of efficiencies and potential comparability vs sensitivity to the underlying paradigm.
Once key questions are clearly defined, the guideline development group typically needs to consider whether to conduct a single sensitive search to address all potential subtopics (lumping) or whether to conduct specific searches for each subtopic (splitting). 36 A related consideration is whether to search separately for qualitative, quantitative and mixed-method evidence ‘streams’ or whether to conduct a single search and then identify specific study types at the subsequent sifting stage. These two considerations often mean a trade-off between a single search process involving very large numbers of records or a more protracted search process retrieving smaller numbers of records. Both approaches have advantages and choice may depend on the respective availability of resources for searching and sifting.
Closely related to decisions around searching are considerations relating to screening and selecting studies for inclusion in a systematic review. An important consideration here is whether the review team will screen records for all review types, regardless of their subsequent involvement (‘altruistic sifting’), or specialise in screening for the study type with which they are most familiar. The risk of missing relevant reports might be minimised by whole team screening for empirical reports in the first instance and then coding them for a specific quantitative, qualitative or mixed-methods report at a subsequent stage.
Within a guideline process, review teams may be more limited in their choice of instruments to assess methodological limitations of primary studies as there are mandatory requirements to use the Cochrane risk of bias tool 37 to feed into Grading of Recommendations Assessment, Development and Evaluation (GRADE) 38 or to select from a small pool of qualitative appraisal instruments in order to apply GRADE; Confidence in the Evidence from Reviews of Qualitative Research (GRADE-CERQual) 39 to assess the overall certainty or confidence in findings. The Cochrane Qualitative and Implementation Methods Group has recently issued guidance on the selection of appraisal instruments and core assessment criteria. 40 The Mixed-Methods Appraisal Tool, which is currently undergoing further development, offers a single quality assessment instrument for quantitative, qualitative and mixed-methods studies. 41 Other options include using corresponding instruments from within the same ‘stable’, for example, using different Critical Appraisal Skills Programme instruments. 42 While using instruments developed by the same team or organisation may achieve a degree of epistemological consonance, benefits may come more from consistency of approach and reporting rather than from a shared view of quality. Alternatively, a more paradigm-sensitive approach would involve selecting the best instrument for each respective review while deferring challenges from later heterogeneity of reporting.
The way in which data and evidence are extracted from primary research studies for review will be influenced by the type of integrated synthesis being undertaken and the review purpose. Initially, decisions need to be made regarding the nature and type of data and evidence that are to be extracted from the included studies. Method-specific reporting guidelines 43 44 provide a good template as to what quantitative and qualitative data it is potentially possible to extract from different types of method-specific study reports, although in practice reporting quality varies. Online supplementary file 5 provides a hypothetical example of the different types of studies from which quantitative and qualitative evidence could potentially be extracted for synthesis.
The decisions around what data or evidence to extract will be guided by how ‘integrated’ the mixed-method review will be. For those reviews where the quantitative and qualitative findings of studies are synthesised separately and integrated at the point of findings (eg, segregated or contingent approaches or sequential synthesis design), separate data extraction approaches will likely be used.
Where integration occurs during the process of the review (eg, integrated approach or convergent synthesis design), an integrated approach to data extraction may be considered, depending on the purpose of the review. This may involve the use of a data extraction framework, the choice of which needs to be congruent with the approach to synthesis chosen for the review. 40 45 The integrative or theoretical framework may be decided on a priori if a pre-developed theoretical or conceptual framework is available in the literature. 27 The development of a framework may alternatively arise from the reading of the included studies, in relation to the purpose of the review, early in the process. The Cochrane Qualitative and Implementation Methods Group provide further guidance on extraction of qualitative data, including use of software. 40
Relatively few synthesis methods start off being integrated from the beginning, and these methods have generally been subject to less testing and evaluation particularly in a guideline context (see table 1 ). A review design that started off being integrated from the beginning may be suitable for some guideline contexts (such as in case study 3—risk communication in humanitarian disasters—where there was little evidence of effect), but in general if there are sufficient trials then a separate systematic review and meta-analysis will be required for a guideline. Other papers in this series offer guidance on methods for synthesising quantitative 46 and qualitative evidence 14 in reviews that take a complexity perspective. Further guidance on integrating quantitative and qualitative evidence in a systematic review is provided by the Cochrane Qualitative and Implementation Methods Group. 19 27 29 40 47
It is highly likely (unless there are well-designed process evaluations) that the primary studies may not themselves seek to address the complexity-related questions required for a guideline process. In which case, review authors will need to configure the available evidence and transform the evidence through the synthesis process to produce explanations, propositions and hypotheses (ie, findings) that were not obvious at primary study level. It is important that guideline commissioners, developers and review authors are aware that specific methods are intended to produce a type of finding with a specific purpose (such as developing new theory in the case of meta-ethnography). 48 Case study 1 (antenatal care guideline) provides an example of how a meta-ethnography was used to develop a new theory as an end product, 48 49 as well as framework synthesis which produced descriptive and explanatory findings that were more easily incorporated into the guideline process. 27 The definitions ( box 5 ) may be helpful when defining the different types of findings.
Descriptive findings —qualitative evidence-driven translated descriptive themes that do not move beyond the primary studies.
Explanatory findings —may either be at a descriptive or theoretical level. At the descriptive level, qualitative evidence is used to explain phenomena observed in quantitative results, such as why implementation failed in specific circumstances. At the theoretical level, the transformed and interpreted findings that go beyond the primary studies can be used to explain the descriptive findings. The latter description is generally the accepted definition in the wider qualitative community.
Hypothetical or theoretical finding —qualitative evidence-driven transformed themes (or lines of argument) that go beyond the primary studies. Although similar, Thomas and Harden 56 make a distinction in the purposes between two types of theoretical findings: analytical themes and the product of meta-ethnographies, third-order interpretations. 48
Analytical themes are a product of interrogating descriptive themes by placing the synthesis within an external theoretical framework (such as the review question and subquestions) and are considered more appropriate when a specific review question is being addressed (eg, in a guideline or to inform policy). 56
Third-order interpretations come from translating studies into one another while preserving the original context and are more appropriate when a body of literature is being explored in and of itself with broader or emergent review questions. 48
A critical element of guideline development is the formulation of recommendations by the Guideline Development Group, and EtD frameworks help to facilitate this process. 16 The EtD framework can also be used as a mechanism to integrate and display quantitative and qualitative evidence and findings mapped against the EtD framework domains with hyperlinks to more detailed evidence summaries from contributing reviews (see table 1 ). It is commonly the EtD framework that enables the findings of the separate quantitative and qualitative reviews to be brought together in a guideline process. Specific challenges when populating the DECIDE evidence to decision framework 15 were noted in case study 3 (risk communication in humanitarian disasters) as there was an absence of intervention effect data and the interventions to communicate public health risks were context specific and varied. These problems would not, however, have been addressed by substitution of the DECIDE framework with the new INTEGRATE 16 evidence to decision framework. A d ifferent type of EtD framework needs to be developed for reviews that do not include sufficient evidence of intervention effect.
Mixed-method review and synthesis methods are generally the least developed of all systematic review methods. It is acknowledged that methods for combining quantitative and qualitative evidence are generally poorly articulated. 29 50 There are however some fairly well-established methods for using qualitative evidence to explore aspects of complexity (such as contextual, implementation and outcome complexity), which can be combined with evidence of effect (see sections A and B of table 1 ). 14 There are good examples of systematic reviews that use these methods to combine quantitative and qualitative evidence, and examples of guideline recommendations that were informed by evidence from both quantitative and qualitative reviews (eg, case studies 1–3). With the exception of case study 3 (risk communication), the quantitative and qualitative reviews for these specific guidelines have been conducted separately, and the findings subsequently brought together in an EtD framework to inform recommendations.
Other mixed-method review designs have potential to contribute to understanding of complex interventions and to explore aspects of wider health systems complexity but have not been sufficiently developed and tested for this specific purpose, or used in a guideline process (section C of table 1 ). Some methods such as meta-narrative reviews also explore different questions to those usually asked in a guideline process. Methods for processing (eg, quality appraisal) and synthesising the highly diverse evidence suggested in tables 2 and 3 that are required to explore specific aspects of health systems complexity (such as system adaptivity) and to populate some sections of the INTEGRATE EtD framework remain underdeveloped or in need of development.
In addition to the required methodological development mentioned above, there is no GRADE approach 38 for assessing confidence in findings developed from combined quantitative and qualitative evidence. Another paper in this series outlines how to deal with complexity and grading different types of quantitative evidence, 51 and the GRADE CERQual approach for qualitative findings is described elsewhere, 39 but both these approaches are applied to method-specific and not mixed-method findings. An unofficial adaptation of GRADE was used in the risk communication guideline that reported mixed-method findings. Nor is there a reporting guideline for mixed-method reviews, 47 and for now reports will need to conform to the relevant reporting requirements of the respective method-specific guideline. There is a need to further adapt and test DECIDE, 15 WHO-INTEGRATE 16 and other types of evidence to decision frameworks to accommodate evidence from mixed-method syntheses which do not set out to determine the statistical effects of interventions and in circumstances where there are no trials.
When conducting quantitative and qualitative reviews that will subsequently be combined, there are specific considerations for managing and integrating the different types of evidence throughout the review process. We have summarised different options for combining qualitative and quantitative evidence in mixed-method syntheses that guideline developers and systematic reviewers can choose from, as well as outlining the opportunities to integrate evidence at different stages of the review and guideline development process.
Review commissioners, authors and guideline developers generally have less experience of combining qualitative and evidence in mixed-methods reviews. In particular, there is a relatively small group of reviewers who are skilled at undertaking fully integrated mixed-method reviews. Commissioning additional qualitative and mixed-method reviews creates an additional cost. Large complex mixed-method reviews generally take more time to complete. Careful consideration needs to be given as to which guidelines would benefit most from additional qualitative and mixed-method syntheses. More training is required to develop capacity and there is a need to develop processes for preparing the guideline panel to consider and use mixed-method evidence in their decision-making.
This paper has presented how qualitative and quantitative evidence, combined in mixed-method reviews, can help understand aspects of complex interventions and the systems within which they are implemented. There are further opportunities to use these methods, and to further develop the methods, to look more widely at additional aspects of complexity. There is a range of review designs and synthesis methods to choose from depending on the question being asked or the questions that may emerge during the conduct of the synthesis. Additional methods need to be developed (or existing methods further adapted) in order to synthesise the full range of diverse evidence that is desirable to explore the complexity-related questions when complex interventions are implemented into health systems. We encourage review commissioners and authors, and guideline developers to consider using mixed-methods reviews and synthesis in guidelines and to report on their usefulness in the guideline development process.

Interviews are a cornerstone of modern health care research and can be used by both experienced and novice researchers to gather data for projects. For qualitative research, the semistructured or unstructured interview is often used and this can be carried out in various ways. Methods discussed in this directed reading include the face-to-face interview, group interviews such as focus groups, and remote interview conducted by telephone or using the computer. These methods are discussed in detail including advantages and disadvantages of each as well as accompanying practical considerations. Regardless of the method used, there are several matters to be considered in the process of planning, conducting, and analyzing interviews. These consist of initially selecting appropriate participants for the study, preparing a research protocol, and writing useful interview questions designed to capture the information required. It is also important for the researcher to be able to develop and demonstrate rapport with the participant and use attentive listening. Ethical issues relating to the conduct of interviews are also considered, including consent, privacy, and confidentiality. Finally, there is a discussion on the method of analyzing qualitative interview data to prepare for its dissemination in the form of an article or presentation.

Nature conservation research is increasingly concerned with the human component as with the ecosystem or species in focus. Natural scientists that are loyal to their education tend to favour quantitative methods. These methods are not necessarily the only and most suitable tools in human dimensions studies. The aim of this article is to describe the importance of quantitative and qualitative research methods in human dimensions studies pertaining to nature conservation, particularly interviewing. Differences between structured, semi-structured and unstructured interviews are explained and examples given. Additionally, some guidelines for conducting a qualitative interview are presented. Research scientists working with human dimension studies should be aware that nature conservation is a complex cultural problem and that complexity and creativity should therefore be recognized when addressing research methodologies.

ASSESSMENT Assessment is a systematic process of gathering information about what a student knows, is able to do, and is learning to do. Assessment information provides the foundation for decision-making and planning for instruction and learning. Assessment is an integral part of instruction that enhances, empowers, and celebrates student learning. Using a variety of assessment techniques, teachers gather information about what students know and are able to do, and provide positive, supportive feedback to students. They also use this information to diagnose individual needs and to improve their instructional programs, which in turn helps students learn more effectively. Assessment must be considered during the planning stage of instruction when learning outcomes and teaching methods are being targeted. It is a continuous activity, not something to be dealt with only at the end of a unit of study. Students should be made aware of the expected outcomes of the course and the procedures to be used in assessing performance relative to the learning outcomes. Students can gradually become more actively involved in the assessment process in order to develop lifelong learning skills. Evaluation refers to the decision making which follows assessment. Evaluation is a judgment regarding the quality, value, or worth of

Data collection is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated research questions, test hypotheses, and evaluate outcomes. The data collection component of research is common to all fields of study including physical and social sciences, humanities, business, etc. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same. The goal for all data collection is to capture quality evidence that then translates to rich data analysis and allows the building of a convincing and credible answer to questions that have been posed (www.en.wikipedia.org). It is an endeavor to discuss about some techniques of data collection.

This study attempts to explain and explore the research methods in Information Systems (IS), while on the other it seeks to provide starting point for their use. In order to support the purpose of this study, a guide was written to introduce a toolkit of methods, explaining how to use them, showing how to analyze the data you obtained, and listing techniques to help you further understand each of the research methods used. More importantly, it aims to help novice or expert researchers to determine the appropriate methods they can apply in their research since the guide provided by this study created a thorough distinction between each research methods. The study employs quantitative research that applies basic descriptive qualitative study. In pursuit of this study’s aim, an existing literature and studies review was done. The literature and studies cited in this study, focus mainly in information systems research and research methods. The literature section reviews IS discipline in literature, IS way back from when it started, IS research in literature, issues concerning IS research and its future. To acquire further understanding about quantitative, qualitative and mixed-method in IS, the researcher sites six related studies to review. All the literature and studies reviewed in this section had showed how the nature of IS are constantly changing and most of the study suggests further advancement in IS research. Consequently, research methods like qualitative, quantitative and mixed-methods can make an important contribution to IS research and development. Thus, the work that described in this study plays an important role to help novice and experienced researchers to learn and review as reference, the use of research methods in evaluating Information System (IS) research. Since the work in this study aims to produce an instructional guide based from the curriculum, a selection of the required textbook for the guide was done. The researcher adopts Seif and Champine Criteria for Selecting Era 3, 21st Century Outcomes Curriculum Materials. Other criteria are also added like book review, cost-efficiency, availability, most recent copy, and content to produce neutral results. The assessment for other criteria like book review, cost-efficiency and availability was done adopting Upstill, Craswell and Hawking observations on their case study in Search and Searchability. The assessment was conducted by the researcher with four books about research methods and design employed and after conducting the assessment one book was selected as the primary textbook while the other three books serves as supplementary textbooks. The guide contains three major sections that explores and explains quantitative, qualitative and mixed-method approaches. The distinctions are based on different fundamental questions about methods used in IS research. Such are: (1) What is the method, (2) 2.When it should be used, (3) What do I need to consider, (4) How it should be used, (5) What is the output, (6) How should it be analyzed, and (7) What are the advantage and disadvantages. Within each distinctions includes the different quantitative methods used in information systems like surveys, experimentation particularly quasi-experiment, and statistical analysis. After the discussion, an example was given and list of readings to further enhance the learning on quantitative methods. The next major section of the guide is the qualitative method where it outlines the core qualitative research methods used in information systems research namely, open-ended and survey questions, participant observation, interviews, and document analysis. Example and further readings is included too. The last part of the guide is the discussion on mixed-method approach. The format of the section when it comes to questions is a little bit different compared to quantitative and qualitative sections because the third section is like the integration part of the two first-mentioned methods. In conclusion, the value of this study resides in the learning and knowledge it can provide for the novice or experienced researchers who are planning to conduct research in information systems or any related area of discipline. This guide reflects the wider aim of this study to support the need of further enhancement in Information Systems (IS) research and development. In this, we hope this guide goes in some way to help make the application rate of Information Systems (IS) research high. The topics within this guide are not fully comprehensive that you should follow-up at least some of the references suggested in further readings since the examples and focus is pointing to Information Systems (IS) research. In addition, the information contained in this study will not always appear in order that suits your perspective and circumstances. Due to this reasons, suggestions for future study were offered.

Data generated from quantitative studies is normally in the form of numbers, whereas a qualitative study will generate data that is in the form of words. These words will most commonly be from transcripts of interviews, written observations of situations or documents. A large amount of textual data is normally produced from a qualitative study, which can make analysis a

Although exclusive breastfeeding is recommended for the first six months of life, research suggests that breastfeeding initiation rates and duration among Indigenous communities differ from this recommendation. Qualitative studies point to a variety of factors influencing infant feeding decisions; however, there has been no collective review of this literature published to date. Therefore, the objective of this scoping review was to identify and summarize the qualitative literature regarding Indigenous infant feeding experiences within Canada, the United States, Australia, and Aotearoa.
Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses- Scoping Reviews and the Joanna Briggs Institute Guidelines, in October 2020, Medline, Embase, CINAHL, PsycINFO, and Scopus were searched for relevant papers focusing on Indigenous infant feeding experiences. Screening and full-text review was completed by two independent reviewers. A grey literature search was also conducted using country-specific Google searches and targeted website searching. The protocol is registered with the Open Science Framework and published in BMJ Open.
Forty-six papers from the five databases and grey literature searches were included in the final review and extraction. There were 18 papers from Canada, 11 papers in the US, 9 studies in Australia and 8 studies conducted in Aotearoa. We identified the following themes describing infant feeding experiences through qualitative analysis: colonization, culture and traditionality, social perceptions, family, professional influences, environment, cultural safety, survivance, establishing breastfeeding, autonomy, infant feeding knowledge , and milk substitutes , with family and culture having the most influence on infant feeding experiences based on frequency of themes.
This review highlights key influencers of Indigenous caregivers’ infant feeding experiences, which are often situated within complex social and environmental contexts with the role of family and culture as essential in supporting caregivers. There is a need for long-term follow-up studies that partner with communities to support sustainable policy and program changes that support infant and maternal health.
Peer Review reports
Nutritional status is a key aspect of infant health with recommendations for exclusive breastfeeding for the first six months of life, which can also influence and be influenced by maternal health and wellbeing [ 1 , 2 ]. Breastfeeding has several benefits for the health and development of infants, including a reduced risk of ear and respiratory infections, obesity, asthma, skin conditions, childhood leukemia, and gastroenteritis [ 3 , 4 , 5 ]. It also supports bonding between the child and parent with improved intimacy [ 3 ]. Additionally, breastfeeding has several maternal physical and mental health benefits, including a reduced risk of breast and ovarian cancer, depression, and type 2 diabetes due to immunoprotective antibodies in breastmilk [ 3 ]. The World Health Organization (WHO) recommends exclusive breastfeeding for the first 6 months of life and initiation within the first hour after birth; however, less than half of infants 0–6 months old are exclusively breastfed worldwide [ 6 ]. Many countries are not meeting the WHO recommendations, with notable differences between low, middle, and high-income countries [ 2 ]. Differences in breastfeeding initiation rates and duration have been observed between Indigenous and non-Indigenous groups, with 6–10% lower breastfeeding initiation rates and shorter duration for Indigenous peoples [ 7 , 8 , 9 ].
Despite the many benefits of breastfeeding, bottle feeding with milk substitutes is a common form of infant nutrition and its common usage is related to a multi-dimensional set of factors influencing infant feeding decision-making. Breastfeeding is considered a traditional practice within many Indigenous cultures; however, disruptions to traditional lifeways through colonization have influenced intergenerational knowledge sharing, particularly within high-income, settler states like Canada, the US, Australia, and Aotearoa (New Zealand) [ 10 ]. Rollins et al. [ 1 ] summarize factors that influence the global breastfeeding environment including the sociocultural and market contexts, the healthcare system and services, family and community settings, employment, and individual determinants like the mother and infant attributes. However, these core breastfeeding environments for general populations overlook key considerations for Indigenous communities given the unique historical, cultural, and socio-economic contexts specific to Indigenous groups [ 11 ].
Many studies to date have focused on quantitative infant feeding data, incorporating structured questionnaires that have provided some insight into breastfeeding barriers and enablers for Indigenous caregivers [ 7 , 12 , 13 , 14 ]. However, these studies are informed by specific research questions and do not capture important nuances that caregivers experience related to infant feeding. Qualitative research can enhance our understanding of phenomena by providing flexible means for participants to engage in the research topic of interest without the constraints of structured instruments, and can even transform the research by highlighting community needs [ 15 , 16 ]. Qualitative research can also have synergy with Indigenous methodologies, supporting the use of qualitative research with Indigenous communities [ 17 ]. Given the value of qualitative inquiry and breastfeeding as traditional practice for many Indigenous cultures, disrupted by colonial influences and the burden of conditions that breastfeeding has been shown to mitigate [ 3 , 5 , 10 , 11 , 16 , 17 ], it is imperative that we consider Indigenous caregiver infant feeding experiences and perspectives to understand what needs exist as defined by communities and caregivers. Therefore, the overall aim of this scoping review was to identify and summarize the qualitative literature on infant nutrition experiences to inform needs as expressed qualitatively by Indigenous caregivers in Canada, the US, Australia, and Aotearoa. These regions are included given the shared colonial influences on Indigenous peoples with overlapping outcomes on health [ 10 , 18 ]. This review will also assess the qualitative methodologies used to understand what can be learned to inform Indigenous infant feeding services, policies, and research gaps.
This scoping review adheres to guidelines from Tricco and colleagues’ [ 19 ] Preferred Reporting Items for Systematic Reviews and Meta-Analyses ( PRISMA) extension for scoping reviews , the Joanna Briggs Institute’s Reviewer’s Manual Chap. 11 [ 20 ], as well as Arksey & O’Malley’s [ 21 ] foundational article on scoping studies. The protocol for the review is registered with the Open Science Framework ( https://doi.org/10.17605/OSF.IO/J8ZW2 ) and published with BMJ Open [ 22 ].
Works included in this review must have focused on Indigenous populations in Canada, the United States, Australia, and/or Aotearoa. These four countries share commonalities in that they are colonial countries in which Indigenous peoples face inequitable health outcomes [ 10 , 18 , 23 ]. The topic of interest for this review was caregivers’ experiences of infant feeding within one or more of these regions. “Caregivers” refer to individuals in the infants’ immediate familial and social circles who are directly responsible for the regular care of the infant. A broad definition of those involved in caregiving was used, recognizing that within many Indigenous communities, traditional adoption practices occur, or biological parents may not be the primary caregivers in part related to complex socio-ecological challenges. The experiences of healthcare professionals were not included as they were not considered “caregivers” by this definition. Works that discussed breastfeeding, as well as alternative forms of infant feeding, such as formula and cow’s milk, were included. Works that only focused on the introduction of solid foods were excluded. To capture caregivers’ experiences of infant feeding, qualitative and mixed-method studies that discussed experiences, perspectives, and/or practices as described by caregivers were included. Studies that used exclusively quantitative methods or that only described an outsider perspective (e.g. health professional) were excluded. Peer-reviewed journal articles and grey literature were included if they met the above criteria, were published in the English language, and were published after 1969 [ 22 ].
Various types of grey literature such as government documents, dissertations, and research reports by academic and non-academic institutions, including Indigenous organizations, were included. Media reports (including videos, news, and blogs) were excluded from the grey literature as they did not follow a research design with results that could be considered alongside the studies included in the review, hindering our ability to compare and critically analyze the results. Similarly, publications that consisted of only an abstract were excluded from both grey and database publications during full-text review as not enough information was present for analysis.
The search strategy was created with guidance from a research librarian at the Gerstein Science Information Centre, University of Toronto. The complete search strategy can be found as supplementary material in our published protocol [ 22 ]. Search terms primarily included broad terminology for Indigenous peoples (e.g. Native American) rather than specific Nation names (e.g. Ojibwe) as this would have significantly extended the search term list while not resulting in additional sources given how sources are indexed within Library systems. A database and grey literature search were conducted for this scoping review, completed independently from one another until final data extraction when the data were combined for analysis. For both searches, the reviewers followed a step-by-step process of title and abstract screening, followed by full-text screening, and then data extraction.
The database search planning and calibration occurred in August and September of 2020, and all data were exported in English on October 20, 21, and 22 of 2020. Exportation occurred over three days given feasibility of exporting the high number of citations and time capacity of the reviewers. A total of 16734 relevant sources available in the following databases were included: Medline, Embase, CINAHL, PsycINFO, and Scopus. These databases were selected to ensure a broad range of research given the multidisciplinary nature of research on this topic. The grey literature search consisted of a targeted search of a variety of Indigenous focused websites specific to the four countries and a thorough Google search with each of the country-specific Google versions (Google.com.au, Google.co.nz, Google.ca, and Google.com) where the first 10 pages of results were reviewed (Supplementary File 1 ). Lastly, Indigenous Studies Portal (I-Portal) was searched as part of the grey literature as this database uses a different indexing system than other research databases. The Canadian Agency for Drugs and Technologies in Health (CADTH)’s “Grey Matters” checklist [ 24 ] was used in the planning and tracking of grey literature searches and findings.
The results of the database search including 16734 citations were uploaded to Covidence (Veritas Health Innovation Ltd., Melbourne, Australia), a data management platform for systematic and scoping reviews, where 3928 duplicates were automatically removed. The 284 results of the grey literature search were recorded on Google Sheets (Alphabet Inc. California, USA) and 146 duplicates were manually removed by the reviewers. Due to the large number of results retrieved in the database and grey literature search, a hand-search of reference lists was not conducted.
A list of key words developed by HM were searched on each site and can be found in Supplementary File 1 . The grey literature search was completed by HM, CC, and HS with all reviewers assigned to search a Country-specific Google database for one of the included countries. Using a template created by Stapleton [ 25 ] at the University of Waterloo based on methods described by Godin et al. [ 26 ], the reviewers kept track of which search terms were searched on the websites, the number of results retrieved, and the number of items screened and saved for further full-text analysis. If a website did not have a search bar, relevant tabs were examined for research, resources, and other publications. I-Portal was originally searched on August 15th, 2021 (yielding 10 results), however the search was revised to remove Indigenous search terms as the database was already Indigenous-specific. The search was repeated on August 18th, 2021, and yielded 77 additional results. The grey literature search was completed between May 25, 2021 – August 18, 2021. No search limitations or filters were used for the grey literature search or the database search.
The database abstract screening was initially completed by HM and CC starting in October 2020. They were then joined by HS and CL in February 2021. To ensure all reviewers had a shared understanding of the eligibility criteria, two search results were screened together and each reviewer discussed their reasoning for inclusion or exclusion. HM also hosted an introductory meeting to review the screening process using Covidence Software [ 27 ] in detail. All 12806 database results were saved in Covidence [ 27 ].
Abstract and full-text screening was completed in Covidence by two independent reviewers. Any conflicts at the screening stage were resolved by AH after all the results had been screened by two reviewers. Full-text screening was completed by HM, AH, and CC, and when conflicts arose, the reviewers met to discuss the difference in opinion until a consensus was reached. A third reviewer joined to offer impartial opinions for full-text conflicts.
Grey literature results were not imported to Covidence. Instead, the team used Google Sheets to organize the publications. Similar to the database review process, each study was screened by two independent reviewers and conflicts were resolved by a third party and discussed for consensus. Full-text review of the grey literature was completed by HM, AH, CC, and HS.
HM compiled a list of variables to extract (Supplementary File 2 ), and the data extraction was completed by HM, AH, and CC in Covidence for database results and Google Sheets for the grey literature. The extraction template was reviewed and tested by all three reviewers using the same two articles. Discussion about any areas of confusion followed by minor edits to the data extraction template were completed prior to extraction.
Only one reviewer extracted data from most publications, however in circumstances where an article was complex or data extraction was not clear given the format of the article, two reviewers extracted data from the publication. An additional subset of five publications were also randomly double-reviewed by HM to ensure consistency in data extraction. There were an additional two articles that were excluded at this step after review and discussion by AH and HM.
Review findings using the extraction template (supplementary file 2 ) were exported into Microsoft Excel (Microsoft Corporation, Washington, USA) and reviewed by HM. HM compiled all data and completed summary figures for variables of interest. The primary analysis consisted of a qualitative review of the included papers’ results and recommendations using a thematic synthesis informed by grounded theory and meta-ethnography, where the included papers are synthesized together, and interpreted using descriptive and analytical themes [ 28 ]. Similar to grounded theory, this process was inductive and identifies themes through comparisons. HM reviewed all extracted data from the excel files, coding for overlapping themes and taking notes throughout. The full-text of the extracted papers were then revisited to identify overall concepts, followed by descriptive themes. Categorization of descriptive themes was completed based on the results and interpretations of included papers. Descriptive themes were refined through additional comparisons between papers. The same analytical process was used for both database and grey literature results, and final analysis involved the integration of themes from the database and grey literature papers. Supplementary file 3 provides a summary table of the included papers in this scoping review.
Of the final sample of 46 articles from which data was extracted (Fig. 1 ), there were studies from each of the four countries, with the most studies (39%) published from Canada. In addition, this qualitative literature on infant feeding included several Indigenous groups within the four countries. The studies retained in this review included authors who identified as either Indigenous or non-Indigenous, and several did not mention positionality (Fig. 2 ). 13% more grey literature studies discussed positionality and had Indigenous sole authorship compared to the database papers. Regarding methodologies utilized, several described Indigenous methodologies and used thematic analysis as an analytic tool (Figs. 3 and 4 ). However, a third of the studies did not describe their theoretical foundations for the qualitative inquiry. Over 60% of the studies were published in the fields of public health and/or nursing as per the authors stated fields of study and/or the Journal’s field, and although there were studies published from 1984 to 2019, 50% of the retained papers were published after 2010.

Summary of theoretical foundations informing the retained studies’ methodologies
Analysis revealed a variety of important themes that aligned with Indigenous and public health perspectives on health, including the socioecological model. There were twelve final overarching themes including colonization, social perceptions, family, professional influences, culture and traditionality , environment (i.e. built environment) , autonomy, survivance, infant feeding knowledge, cultural safety , milk substitutes , and establishing breastfeeding with evidence of connections among these themes. These themes are shown in Fig. 5 in a circular pattern where the themes intersect with the infant and caregiver represented at the centre. This model is conceptually aligned with that of Dodgson et al. [ 30 ], who considered the “contextual influences within the social structures of family and community, Ojibwe culture, and mainstream culture.”
Scoping review research model of themes
The twelve final themes are shown as the main influences on infant feeding experiences. The themes are arranged in a circular pattern with the infant and caregiver represented at the centre, emphasizing the connection between all of the themes
There were 14 papers that discussed colonization of Indigenous peoples as a key factor influencing infant feeding decisions and experiences (Fig. 6 ) [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. Colonization has meant the dispossession of land and limited access to culturally safe healthcare, malnutrition, and loss of language through residential schools, loss of culture and traditional knowledge through assimilation and separation of families, disrupting breastfeeding practices and limiting income for infant formula. Eni et al. [ 36 ] described the policies leading to evacuation from communities to tertiary-care hospitals for birthing as the medicalization of birthing practices, which creates various challenges for First Nations women in Canada. One participant also shared about the impacts of intergenerational trauma related to colonization on breastfeeding, ‘‘You can’t teach about breastfeeding technique and think things will change. It’s the spirit that’s been affected, our experience with trauma. Our women need to relearn how to bond with their children.’’.
A qualitative study with Aboriginal Australian first-time mothers noted the disruptions to breastfeeding practices over time, providing a historical chart detailing how infant feeding practices changed as a result of colonial influences [ 38 ]. Brittany Luby [ 39 ] described how hydroelectric flooding from 1900 to 1975 in Northwestern Ontario reduced breastfeeding practices for Anishinabek mothers and their infants. Although not all studies specifically discussed history and colonization, those that considered the broader historical context highlighted how important this issue is in understanding the factors that lead to infant feeding decisions, particularly those that do not align with breastfeeding as a traditional feeding practice.
Frequency of identified themes in the database papers and the grey literature
Culture , including traditionality, was the second most described theme throughout all papers, identified both directly and indirectly in 31 papers (Fig. 6 ) [ 30 , 31 , 32 , 34 , 35 , 37 , 38 , 39 , 40 , 41 , 42 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ]. The Navajo Infant Feeding Project focused on cultural beliefs influencing infant feeding practices within three Navajo communities in the United States [ 48 ] and emphasized breastfeeding’s significance for nutritional, physical, and psychological health where mothers not only pass along physical health benefits, but also their wellbeing to their children. The Baby Teeth Talk Study in Cree communities in Northern Manitoba, Canada, has identified breastfeeding as a cultural intervention for the prevention of early childhood caries [ 52 ]. Several studies included a variety of generations in data collection, contributing to rich discussion of how breastfeeding rates and connection to traditionality has changed in some communities [ 48 , 57 , 64 , 65 ]. For example, grandmothers living on the Fort Peck Reservation in Montana, US, were interviewed about their perspectives on infant feeding [ 65 ]. In one of the ethnographic studies, there was a specific focus on the Ojibwe culture relating to infant feeding practices from the perspective of mothers, professionals who were also community members, and Elders [ 35 ]. This study emphasized the holistic and collective worldview of the community, influencing women’s roles within the family and how teachings were passed on from generation to generation [ 35 ]. This was considered to be important in influencing effective and culturally safe breastfeeding promotion. Within the Northwest Territories, Canada, Moffitt and Dickinson [ 53 ] supported breastfeeding knowledge translation tools for Tłı̨chǫ women with one of the themes focused on factors that “pull to breastfeeding,” including breastfeeding as a traditional feeding method. In general, Indigenous communities described breastfeeding as a cultural practice; however, how this is supported and the traditional knowledge surrounding this practice may differ from community to community. Therefore, health providers must be aware of community-specific protocols and support these within programs and recommendations.
Societal influences are often considered alongside cultural perspectives of infant feeding; therefore, this theme was also commonly discussed in the papers retained in this scoping review (Fig. 6 ) [ 30 , 32 , 33 , 36 , 37 , 38 , 40 , 42 , 49 , 50 , 52 , 54 , 57 , 58 , 59 , 61 , 64 , 66 , 67 , 68 , 69 , 70 , 71 ]. In New South Wales, Australia, Aboriginal mothers and key informants noted the need for “a safe place to feed,” including concerns about the social acceptability to breastfeed in public [ 32 ]. Broader social “norms” are also discussed as influencing maternal behavior [ 68 ], and respondents in some studies expressed concern about judgements from others [ 32 , 36 ]. Tapera et al. [ 40 ] described concerns about social pressures and a lack of support with one grandparent sharing, “well here in New Zealand, I know we have a problem with this [breast-feeding], especially when mothers go out and they breast-feed their babies in public. There’s a lot of people that moan and groan about this.” Similarly, regarding social norms, a grandmother living in the US shared,
“a long time ago that, it [breastfeeding] was acceptable and nobody had any qualms about it but today, I mean you read continually about, people, mother’s tryin’ ta breastfeed and they’re being chased out a places or stores or people are rude about it […]. Society’s changed, you know, it’s […] society, has come to the point where it’s […] trying to tell us what’s the right way ta live what’s the right way ta raise our kids” [ 65 ].
Dodgson et al. [ 30 ] described how in an Ojibwe community in Minnesota, US, participants noted the dominant societal influences in contrast to community traditions, with women making an effort to engage in traditional practices. The sexualization of breasts in mainstream society sometimes influenced Indigenous mothers’ infant feeding experiences [ 36 ], although Ojibwe caregivers in Minnesota attributed shyness with breastfeeding to traditional value opposed to sexualization of breasts [ 30 ]. Eni et al. [ 36 ] included sexual objectification of the feminine body as a subtheme in their study, describing how this social perception damages maternal mental health, creating a barrier to breastfeeding. While shifting social norms is a significant challenge, breastfeeding supports can address concerns about the sexual objectification of breasts by creating safe spaces for parents to talk about the challenges and ensure that parents have access to mental health resources.
Dodgson et al. [ 30 ] described family as a pattern that influences breastfeeding intersecting with the social structures of the community, culture, and the broader society. There were 33 other papers that described the influence of family on infant feeding practices making this the most discussed theme (Fig. 6 ) [ 30 , 31 , 32 , 33 , 36 , 38 , 39 , 40 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 53 , 54 , 55 , 57 , 58 , 59 , 60 , 61 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 ]. Native American mothers living in six communities highlighted the importance of family as a key theme [ 47 ]. One mother shared, “For me, it’s my mom definitely [whose advice is most important] because she has had three kids and I lived with her or near her for all of my kids. So I’ve always gone to her first for advice.” This was echoed by many other participants with a paraprofessional adding, “family [advice is most important], because they are around their family most. And they always hear from their aunties, or from grandma, baby’s fussing, baby must be hungry, baby needs this and baby needs that.” The Baby Basket Program in Cape York, Australia identified that empowering families was the foundation of the program to ensure that mothers and their partners were equipped for the arrival of their babies [ 50 ]. Family often plays an integral role in supporting mothers in infant feeding practices. Bauer and Wright [ 45 ] note that even when mothers don’t have other supports or conditions in place to support breastfeeding, they may still choose to breastfeed if their family is supportive. However, when this support is lacking, mothers find it challenging to breastfeed [ 31 , 36 ]. Some studies identified the significance of family in the study design, integrating family caregiver perspectives in data collection [ 64 , 65 ]. Therefore, health programs and research studies should consider the role and experience of non-primary caregivers within family networks for infant and maternal health and nutrition.
This theme represents the influence of formal systems including healthcare professionals, health and social programs, child services, and the legal system. In total, there were 26 papers that referenced professional influences on infant feeding experiences (Fig. 6 ) [ 30 , 31 , 33 , 38 , 41 , 42 , 43 , 45 , 47 , 48 , 50 , 51 , 52 , 54 , 58 , 59 , 61 , 62 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 ]. Some studies incorporate health workers as participants in data collection [ 47 , 50 , 65 ]. One health paraprofessional shares about some of the pressures experienced by mothers to formula feed, “sometimes hospitals and doctors want to push formula in bottles on moms [ 47 ].” One of the main themes in a study with Sioux and Assiniboine Nations in the US was the ‘ Overburdened Healthcare System’ , describing a lack of resources and infrastructure to support breastfeeding, including a subtheme of mistrust in the healthcare system due to previous negative experiences such as forced sterilization of Indigenous women [ 65 ]. However, some caregivers also expressed positive healthcare supports, “when I was at home, [clinic midwife] and [lactation consultant made home visits] … they encouraged me … And then it started getting a little bit better, but it was still a bit hard. Now he feeds pretty all right [ 73 ].” Professional influences on infant feeding are nuanced and may differ significantly within various contexts and individuals; therefore, tailored interventions are needed.
This theme represents the external variables within the built environment that influence decision making including work, school, remoteness, and cost of formula. Eighteen papers addressed this theme [ 30 , 31 , 44 , 45 , 46 , 47 , 48 , 49 , 51 , 53 , 58 , 59 , 66 , 67 , 68 , 70 , 71 , 72 ]. Wright et al. [ 74 ] specifically considered the challenge of breastfeeding with maternal employment among the Navajo population in the US. In Bauer and Wright’s [ 45 ] study that explored infant feeding decision models, they identified that work and school are part of the decision-making process on whether to breastfeeding or to use formula, but even when these environmental challenges are present they can be further influenced by other factors, like family . For example, a mother may choose to breastfeed and use a breast pump to navigate work/school schedules, but family members may recommend that they can incorporate formula; decision-making is not only about the main caregiver’s desires but can involve various decision-makers.
This theme describes parents’ freedom to make infant feeding decisions that fit for them and their priorities. Maternal desire to breast- or bottle-feed was discussed in select papers in this review [ 45 , 51 ]. In addition, other papers describe parents’ freedom to do activities outside of infant feeding in the early months of baby’s life with discussion of time required to breastfeed or prepare bottles for feeding [ 31 , 58 , 72 , 74 ]. A key informant in a study with an Aboriginal community in Northern New South Wales, Australia, shares, “they want to breastfeed, but then it comes down to when they want to go out, or keep up with their man [ 32 ].” Some parents report that they experienced judgements from others or feel forced into making a specific decision on infant feeding method, highlighting a desire to have support and freedom to make their own decisions [ 36 , 56 ].
Several studies emphasize the importance of knowledge on infant feeding experiences, highlighting the value of infant feeding education, both within the overall healthcare system and from traditional teachings [ 30 , 32 , 35 , 40 , 42 , 43 , 47 , 52 , 57 , 58 , 62 , 64 , 66 , 67 , 68 , 69 , 70 , 71 , 72 ]. Within the theme of addressing feeding challenges in one study [ 66 ], a caregiver shared how knowledge helped her to work through a challenge,
“He did start fussing at about 6 weeks and that was kind of hard because I thought, ‘No, I have got this perfect now, and he has started to muck up’. But then I read, because I had those booklets and I read that sometimes they — at a certain point — they get a bit fussy and you just have to work through it. [Ml7]” [ 66 ].
Traditional breastfeeding knowledge is important for many communities; one Anishinaabe community knowledge keeper shared that “breast milk is a gift and a medicine a mother gives her child” [ 35 ]. This study also discusses feeding patterns as shared by Elders and traditional teachers. Traditional knowledge considers holistic perspectives of health where caregivers are also focused on the baby’s spiritual wellbeing [ 48 , 56 ].
Bottle feeding (formula or canned milk) and solid foods are described in several papers as alternatives or complements to breastfeeding [ 31 , 33 , 34 , 37 , 39 , 47 , 48 , 49 , 51 , 52 , 53 , 58 , 66 , 67 , 74 , 75 ]. In Neander and Morse’s [ 37 ] study with a Cree community in Alberta, Canada, bottle feedings were offered particularly when mothers felt that they were not producing adequate milk supply to meet the baby’s nutritional needs. Insufficient milk supply is echoed as a concern in several other papers resulting in complementary bottle feeding or weaning [ 48 , 51 , 56 , 66 , 67 ]. A Māori father shares,
“about the second week, baby just wanted more food. She (partner) would end her day and baby was just hungry. We had to [give her] the bottle and then she would be finally satisfied. It wasn’t that she made a choice. Baby was actually demanding more and more and she couldn’t produce it. (First-time father, mid 20’s) [ 56 ].”
This theme particularly overlaps with autonomy as parents balance infant feeding decisions with breastmilk supply, work, school, and other personal commitments.
Indigenous caregivers interact with a variety of health services postnatally; however, there is a need to address cultural safety within the healthcare system. Twelve retained papers highlighted this theme either directly as one of their themes or as part of another theme (Fig. 6 ) [ 30 , 31 , 44 , 47 , 50 , 64 , 66 , 67 , 69 , 71 , 73 , 74 ]. One health worker in Victoria, Australia, shared,
“I can’t say often enough or long enough, loud enough the ideal for children 0–8 is to have access to maternal and child health. You might say ‘oh yes, they’ve got access to mainstream and they’re culturally going to put up a few Indigenous prints in their rooms’ It’s not the same. Our families are telling us with their feet it’s not the same.”
Mothers expressed a desire for more traditional infant feeding knowledge within services and culturally relevant supports [ 47 , 64 ]. A study that focused on a baby basket program to support families in a Murri (Local Australian Aboriginal Group) Way identified how important culturally safe language and relationships are for families,
“…the nurse is also learning what the best way is to approach a family and what the wording has to be, what the languaging is around things, what the traditional words are for Indigenous language and are appropriate for use in certain circumstances” [ 50 ].
Indigenous caregivers experience a variety of hardships; however, through resistance and survival, they practice cultural revitalization [ 76 ]. This theme is discussed in 15 papers and is often described through a lens of maternal mental health (Fig. 6 ) [ 30 , 31 , 33 , 43 , 53 , 54 , 57 , 58 , 59 , 63 , 64 , 66 , 68 , 36 , 74 ]. Some parents express feelings of guilt for the challenges they encounter, which can further contribute to negative emotions [ 58 ]. Maternal mental and emotional health can impact infant feeding experiences,
“…sometimes people’s psychological health, mental health is more of a risk factor, you know if you’re not sleeping and you’re bordering on depression and you’re not coping well and you can’t get the baby to latch and you’re constantly feeling like a failure and you can’t get out of that rut, is it worth it?…People have to decide that for themselves. (Key Informant #5)” [ 33 ].
A grandmother in the Northwest Territories of Canada noted the disembodiment caused by residential schools as expressed as a disconnection between physical experiences and relationships,
“You know in those days, I mean residential school. In those days, they never did talk about their body parts because I think they were too ashamed [of your body] to say to your kids. I never did hear it [breastfeeding] from my sisters or nobody in the family. They were so private (L151-156)” [ 57 ].
Traumatic experiences, like residential schools, can have a lasting impact on how caregivers navigate motherhood and infant feeding, and the support they receive from family members.
There are several practical challenges that mothers encounter while breastfeeding like pain, latching issues, and low milk supply, discussed in 11 of the studies (Fig. 6 ) [ 48 , 51 , 54 , 56 , 58 , 61 , 66 , 68 , 71 , 72 ]. A mother shared,
“He wouldn’t latch on all the time, like, the nurses and stuff tried to help me but then it would be all frustrating…. He didn’t really know what to do. He tried and then they gave him formula. He really loved it. [MI5]” [ 66 ].
Although these challenges are most discussed at the beginning of breastfeeding, sometimes concerns arise when babies are older.
“Yeah it was 8 or 9 months after she was born. After a while there was too much pressure on me. She was getting up all through the night and she would eat and eat and eat and not get full…” [ 33 ].
Overall, many caregivers reported that breastfeeding is difficult; therefore, supports that consider the variety of challenges that can arise are needed.
The studies included in this review were published over three decades starting in 1984 until 2019 and were completed with various Indigenous communities in four countries. We anticipated that earlier work would demonstrate markedly different infant feeding recommendations than more recent research; however, this was not necessarily the case. For example, cultural safety is a more recent discussion within the health literature; however, although we see some discussion of this in more recent studies, studies in the 80’s and 90’s also highlight the importance of incorporating traditional teaching and consulting community members [ 37 , 48 ]. Therefore, supporting Indigenous self-determination where health professionals provide culturally appropriate care is essential.
In addition to topics related to cultural safety, various studies highlight a need for community-driven and local knowledge to inform programs and policies related to infant nutrition [ 31 , 47 , 57 , 64 , 75 ]. Several studies also focus on infant feeding specific programs and behavioral changes in their recommendations [ 47 , 50 , 65 ]; however, many of these studies also highlight the need to expand beyond the individual’s role in decision making and address the broader social and environmental factors such as the workplace, healthcare infrastructure, social perceptions, among others, that influence infant feeding decisions. For example, Eni et al. [ 36 ] note that there are a complexity of factors resulting in various breastfeeding environments. These structural, social and cultural contexts are discussed throughout several of the grey literature texts as well [ 32 , 33 ]. It is also important to note that in the most recently published database paper, maternal mental health is directly addressed in the recommendations and this is the only paper with this focus for next steps [ 65 ]. Interventions that target socio-ecological factors based on the included papers’ recommendations for infant feeding are summarized in Fig. 7 .

The components of Indigenous infant feeding environments informed by community-based interventions
This scoping review presents and summarizes the findings reporting Indigenous infant feeding experiences within the qualitative literature in Canada, the US, Australia, and Aotearoa. Twelve themes were identified which summarize the literature including culture and traditionality , colonization, family, environment, social perceptions, professional influences, milk substitutes, breastfeeding initiation, cultural safety, survivance, infant feeding knowledge, and autonomy. The most prevalent themes discussed by caregivers and researchers in the included papers were family and culture/traditionality . The frequency of these two themes highlight the significant impact of family and culture/traditionality on infant nutrition decision-making for Indigenous caregivers and overlaps with components of the socio-ecological model [ 77 ]. This focus on family and culture/traditionality also emphasizes the importance of familial relationships and a collective mentality within traditional life ways for many Indigenous communities in these regions on infant nutrition and care practices.
In their informative global breastfeeding paper, Rollins and colleagues’ [ 1 ] conceptualize the components that contribute to the breastfeeding environment at multiple levels, overlapping with the social determinants of health. In this review, we observed that caregivers report similar components of the breastfeeding environment; however, these components seem to be described collectively, rather than as separate contexts. This is evident in the recommendations proposed by authors with a large focus on local and community-specific leadership, multidisciplinary interventions, and cultural safety in response to historical traumas, particularly within the healthcare system (Fig. 7 ). This aligns with Indigenous epistemology with an emphasis on the collective and interconnectedness of all things where power is manifested together, not over one another, and is based in local land-based knowledge [ 78 , 79 ].
A primary recommendation echoed within many of these studies was the need for community engagement in program and policy development [ 34 , 47 , 50 , 64 ]. This may need to be expanded upon to support Indigenous self-determination of policy and programs related to infant feeding where community members are not only engaged but leading the way forward in maternal and infant health. It is important to note that there have been changes over time in how these recommendations and perspectives are discussed and the role of the health professional, particularly related to cultural safety. For example, although similar concepts are discussed in Neander and Morse’s paper published in 1989, ‘cultural safety’ is not used as the terminology, which has been expanded upon in recent years by Indigenous and non-Indigenous scholars [ 37 , 80 , 81 ].
Related to this focus on health professionals and cultural safety, it’s important to distinguish that in many of the positive experiences expressed by participants in the studies, these interactions seemed to be primarily with professionals interacting closely with families. For example, midwives, who make home visits, were often included as part of positive experiences. In the literature, there is an emphasis on including practitioners who can build strong relationships with families through home visits and regular community engagement in routine services, which supports cultural safety within the healthcare system [ 82 , 83 ]. Health professional regulatory bodies should consider implementing practice competencies that support professionals to build and navigate strong and ethical relationships with clients/patients. Similarly, healthcare settings that serve Indigenous peoples should consider processes and therefore, facility infrastructures that enable close family-client-professional interactions. An example of this implementation with positive client experiences is the Toronto Birthing Centre, which uses an Indigenous framework and has birthing rooms with space for family [ 84 ].
The studies in this review are written within various fields of research; therefore, there were differences in methodological reporting. Future qualitative work should be thorough in reporting theoretical foundations to provide clarity of how the analyses and overall projects are approached (Fig. 4 ) [ 85 ]. Given the limited studies that report author/researcher positionality (Fig. 2 ), this may be an important addition in forthcoming work as a means of respecting Indigenous and qualitative literature conventions where we recognize that positionality influences ontological origins [ 86 ]. We challenge the academy to recognize that Indigenous and local knowledges are required within Indigenous health research and dissemination practices, while acknowledging our own limitation in this review of a single country authorship team.
This systematic scoping review utilized a rigorous search strategy that limited the possibility of missing relevant publications; however, it was time intensive. PRISMA-ScR guidelines were followed with two independent reviewers at each stage, enabling reproducibility of this review. The inclusion of the grey literature is a strength in this study as it captured important papers that were not published in peer-reviewed journals, often from Indigenous authors and communities (many of which were graduate dissertations), which was a priority in this review. A possible limitation is the exclusion of work that only discussed the introduction to solid foods; it is possible that this excluded an important conversation about the differences of introducing solids, like traditional foods from an Indigenous group’s perspective. In addition, the topic of this review is multidisciplinary; therefore, it is possible that although effort was made to include a broad range of research field databases in the search, relevant sources may have been missed.
In conclusion, this scoping review highlights important considerations for infant feeding environments within Indigenous communities with a focus on family and culture. Based on caregiver experiences, Indigenous breastfeeding supports must be community led with a focus on local capacity and traditional teachings. An emphasis on an intergenerational perspective that considers structural and systems approaches including cultural safety within healthcare, addressing maternal mental health, and consideration of sustainability over time is encouraged. Future work should focus on these key areas through strength-based research approaches, grounded in strong relationships and long-term follow-up.
