Selecting and Improving Quasi-Experimental Designs in Effectiveness and Implementation Research
Quasi-experimental designs (QEDs), which first gained prominence in social science research , are increasingly being employed to fill this need. ... (ITS) design involves collection of outcome data at multiple time points before and after an intervention is introduced at a given point in time at one or more sites (6, 13).
Quasi-Experimental Research Design
Quasi-experimental design is a research method that seeks to evaluate the causal relationships between variables, but without the full control over the independent variable(s) that is available in a true experimental design. ... Data collection may also include collecting data on other variables that may impact the dependent variable(s).
Quasi-Experimental Design
Revised on January 22, 2024. Like a true experiment, a quasi-experimental design aims to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria.

Abstract. Objective: To identify variables that must be coded when synthesizing primary studies that use quasi-experimental designs. Study design and setting: All quasi-experimental (QE) designs. Results: When designing a systematic review of QE studies, potential sources of heterogeneity-both theory-based and methodological-must be identified.
Experimental and Quasi-Experimental Designs in Implementation Research
Quasi-experimental designs include pre-post designs with a nonequivalent control group, interrupted time series (ITS), and stepped wedge designs. ... First, data collection for late-implementing sites did not begin until immediately before the onset of implementation support (see Figure 2). While this reduced statistical power, it also ...

The data-collection stage of any meta-analysis is crucial because other stages such as data analysis will depend on what has been coded. In addition to effect-size information, study characteristics that could potentially modify the magnitude of effects across studies should be systematically coded. ...

Quasi Experimental Design Overview & Examples
Quasi-experimental research is a design that closely resembles experimental research but is different. The term "quasi" means "resembling," so you can think of it as a cousin to actual experiments. In these studies, researchers can manipulate an independent variable — that is, they change one factor to see what effect it has.
The Use and Interpretation of Quasi-Experimental Studies in Medical
In medical informatics, the quasi-experimental, sometimes called the pre-post intervention, design often is used to evaluate the benefits of specific interventions. The increasing capacity of health care institutions to collect routine clinical data has led to the growing use of quasi-experimental study designs in the field of medical ...
Quasi-experimental study designs series—paper 9: collecting data from
Introduction. In this article, we describe the data that should be collected by authors of systematic reviews of quasi-experiments (QEs). Broadly, the categories of data that need to be collected from QE studies are the same as those needed for systematic reviews of experimental studies (i.e., randomized controlled trials), namely information needed to (1) describe the included studies in ...
Unraveling the Quasi-Experimental Design: A Comprehensive Guide
Quasi-experimental design, at its core, is a research method where the researcher doesn't randomly assign participants to treatment or control groups. It's a step away from the rigidity of true experimental designs but offers more structure than observational studies. Contrary to true experimental designs, where variables are controlled ...
How to Use and Interpret Quasi-Experimental Design
A quasi-experimental study (also known as a non-randomized pre-post intervention) is a research design in which the independent variable is manipulated, but participants are not randomly assigned to conditions. Commonly used in medical informatics (a field that uses digital information to ensure better patient care), researchers generally use ...

For instance, the original work of [7] labels different designs (e.g., time-series, regression discontinuity) simply as quasi-experimental designs. ... The data-collection stage of any meta-analysis is crucial because other stages such as data analysis will depend on what has been coded. In addition to effect-size information, study ...
Use of Quasi-Experimental Research Designs in Education Research
The increasing use of quasi-experimental research designs (QEDs) in education, brought into focus following the "credibility revolution" (Angrist & Pischke, 2010) in economics, which sought to use data to empirically test theoretical assertions, has indeed improved causal claims in education (Loeb et al., 2017).However, more recently, scholars, practitioners, and policymakers have ...
14.3 Quasi-experimental designs
Quasi-experimental designs are common in social work intervention research because, when designed correctly, they balance the intense resource needs of true experiments with the realities of research in practice. ...

Quasi-Experimental Design: Types, Examples, Pros, and Cons
See why leading organizations rely on MasterClass for learning & development. A quasi-experimental design can be a great option when ethical or practical concerns make true experiments impossible, but the research methodology does have its drawbacks. Learn all the ins and outs of a quasi-experimental design.
Experimental Design: Definition and Types
An experimental design is a detailed plan for collecting and using data to identify causal relationships. Through careful planning, the design of experiments allows your data collection efforts to have a reasonable chance of detecting effects and testing hypotheses that answer your research questions. An experiment is a data collection ...
Quasi-experimental designs for causal inference: an overview
The randomized control trial (RCT) is the primary experimental design in education research due to its strong internal validity for causal inference. However, in situations where RCTs are not feasible or ethical, quasi-experiments are alternatives to establish causal inference. This paper serves as an introduction to several quasi-experimental designs: regression discontinuity design ...

Choosing the appropriate study design is critical when performing antimicrobial resistance intervention studies. When randomized studies in single hospitals or multihospital cluster-randomized trials are infeasible, investigators often choose before-and-after quasi-experimental designs [1, 2].Quasi-experimental studies can assess interventions applied at the hospital or unit level (e.g ...
