What can be done to control the placebo response in clinical trials? A narrative review
Abstract. The desire to reduce high placebo response rates in clinical trials is a popular concept. However, few studies have rigorously examined the effectiveness of methods to control for placebo responses that are relevant to randomized controlled trials. The primary objective of this review was to evaluate the effect of experimental placebo ...
Strategies to minimize placebo effects in research investigations
For the purpose of clinical trials, placebo interventions should be manufactured, stored and administered in a way that prevents study participants and research staff to differentiate them from active interventions. Conceptually they translate into the so-called placebo effect, which is measured as a magnitude of effect called the placebo response.
Strategies to minimize placebo effects in research investigations
Placebo-controlled trials are the research standard to evaluate new interventions for which there is no standard of care. While lessening performance and detection bias, such design provides a direct mode of comparison against the probed intervention. Still, using placebo arms may pose new challenges to the design, conduct and analysis of ...
Controlling for the Placebo Effect
A placebo is defined as a medical treatment or preparation with no specific pharmacological activity with effects that are only psychological. In a study, comparing a drug to a placebo can help determine efficacy and side effects. In a perfect world, only the active drug in a study would exert an effect, and the placebo would allow the natural ...
What Is the Placebo Effect?
Placebo effect examples. The placebo effect illustrates how the mind can trigger changes in the body. Example: The power of suggestion. In a study, participants are given a placebo but are told it's a stimulant. While talking about the "medication," researchers are convincing and positive about the expected results.
Methods for assessing and controlling placebo effects
Various alternative methods have been proposed for analyzing placebo and treatment effects in studies where large placebo effects are expected or have already occurred. This paper presents an overview of methodological work that has been proposed for assessing and/or controlling for placebo effects in randomized trials.
Placebo Effect
The placebo effect is the phenomenon where a subject experiences an effect from an inactive substance or fake treatment, which is called a placebo. While not all people experience the placebo effect (certainly not in all situations), there are genuine therapeutic effects of placebos. Here is a look at what the placebo effect is, why it occurs, and how scientists and health professionals use it.
Methods for assessing and controlling placebo effects
The placebo serves as an indispensable control in many randomized trials. When analyzing the benefit of a new treatment, researchers are often confronted with large placebo effects that diminish the treatment effect. Various alternative methods have been proposed for analyzing placebo and treatment …
Enhancing Placebo Effects: Insights From Social Psychology
However, in clinical practice there may be significant benefits in enhancing placebo effects. Prior research from the field of social psychology has identified three factors that may enhance placebo effects, namely: priming, client perceptions, and the theory of planned behavior. These factors are reviewed and illustrated via a case example.
The Placebo Effect: How It Works
The placebo effect is a self-fulfilling prophecy, and it follows the patterns you'd predict if the brain were, indeed, producing its own desired outcomes. Researchers have found, for example ...
Effects and Components of Placebos with a Psychological ...
Therefore, we set out to assess the effects and possible components of placebos provided with a psychological treatment rationale in three experiments on healthy subjects.
Advancing the understanding of placebo effects in psychological
Addressing these concerns is methodologically and at times conceptually challenging. However, developments in the conceptualisation and study of placebo effects from the fields of psychology, neuroscience, pharmacology, and human performance offer guidance for advancing the understanding of placebo effects in psychological responses to exercise.
Placebo and nocebo effects: from observation to harnessing and ...
Placebo and nocebo effects are salubrious benefits and negative outcomes attributable to non-specific symbolic components.
What Is the Placebo Effect and Is It Real?
An example of a placebo would be a sugar pill that's used in a control group during a clinical trial. The placebo effect is when an improvement of symptoms is observed, despite using a nonactive ...
The power of the placebo effect
The placebo effect is more than positive thinking — believing a treatment or procedure will work. It's about creating a stronger connection between the brain and body and how they work together. Placebos won't lower your cholesterol or shrink a tumor. Instead, placebos work on symptoms modulated by the brain, like the perception of pain.

Deception in Research on the Placebo Effect
A common feature of research investigating the placebo effect is deception of research participants about the nature of the research. Miller and colleagues examine the ethical issues surrounding such deception.
The placebo effect: Amazing and real
Whatever the reason, there is a downside to this trend. A powerful placebo effect makes it harder for researchers to prove that a new medication is effective. The stronger the placebo effect, the more difficult it becomes to demonstrate a significant difference between a placebo and an active drug — even if the active drug is pretty good.
[Placebo and nocebo : How can they be used or avoided?]
Placebo and nocebo effects are strongly sensitive to the context. They are dependent on the experiences and conceptions of the individual patient, as well as on the physician-patient relationship. The latter can provide the best protection against harm from risk disclosure. In addition, the expectations of patients and their consequences are ...
Placebo effect involves unexpected brain regions
Placebo-derived pain relief, or placebo analgesia, is the most well-studied and probably the most robust example of the placebo effect 2, and it is produced mainly by the expectation of relief ...
Day Two: Placebo Workshop: Translational Research Domains and ...
The National Institute of Mental Health (NIMH) hosted a virtual workshop on the placebo effect. The purpose of this workshop was to bring together experts in neurobiology, clinical trials, and regulatory science to examine placebo effects in drug, device, and psychosocial interventions for mental health conditions. Topics included interpretability of placebo signals within the context of ...

Experimenter Bias (Definition + Examples)
Experimenter bias occurs when a researcher either intentionally or unintentionally affects data, participants, or results in an experiment. The phenomenon is also known as observer bias, information bias, research bias, expectancy bias, experimenter effect, observer-expectancy effect, experimenter-expectancy effect, and observer effect.
placebo effect
The researchers knew from earlier human brain imaging studies that the placebo effect activates certain brain areas, including the anterior cingulate cortex, which is involved in emotion, attention, and mood. By conducting a series of more detailed studies in mice, the team sought to learn more about the specific brain activities involved.
Placebo effect studies are susceptible to response bias and to other
Investigations of the effect of placebo are often challenging to conduct and interpret. The history of placebo shows that assessment of its clinical significance has a real potential to be biased. We analyse and discuss typical types of bias in studies ...
The gender effects of COVID: evidence from equity analysts
We use COVID-19 and sell-side analysts as an experiment to study the effects of gender on labor productivity. We find that the forecast accuracy of female analysts declined more than that of male analysts, especially when schools were closed and among analysts who were more likely to have young children, were inexperienced, were busier, or lived in southern states of the US. Relative to male ...

Hypertension is a major risk factor for heart disease and stroke. Garlic has a long history of use in traditional medicine for various conditions, including hypertension. This narrative review examined the scientific evidence on the efficacy of garlic in lowering blood pressure. It explores the historical uses of garlic in different cultures for medicinal purposes and delves into the ...
