Which means that neither participants nor researchers know which group is receiving which treatment?

Frequently Asked Questions -------------------------- Daniel J. Simons and Walter Boot *This document provides some definitions and then answers questions about the claims in our paper. If you have questions not addressed in this FAQ or in the paper, please email us.* ---------- Some Definitions ---------------- *Randomized Controlled Trial (RCT)*: A randomized controlled trial is an intervention
study that includes at least one treatment condition and at least one control condition, with participants randomly assigned to the conditions. *Double Blind Design*: In a double blind design, both the participants and the experimenters are kept in the dark about the condition assignment. That is, participants do not know whether they are in a treatment condition or a control condition, and experimenters do not know which participants are in each condition. In a single-blind design, participants
do not know whether they are in the treatment or control condition, but experimenters are aware of the condition assignments. *Placebo-controlled design*: A placebo control condition is one that appears in all respects to be identical to the treatment condition but that lacks the critical ingredient of the treatment. *Active Control*: An active control group is one in which participants engage in some task during the intervention period. Active control groups are not necessarily matched to the
treatment group in any way, and the tasks performed by an active control group might differ in many ways from those performed by the experimental group. *No-Contact control*: A no-contact control group takes the same pre-test and post-test as the treatment group, but does not complete any task during the intervention period (they have no contact with the experimenters). *Waitlist control*: A waitlist control group believes that they will receive the treatment at some later point. Typically, such
participants do not complete the pre-test with the treatment group. They typically do complete the post test. *The gold standard*: The gold standard for an intervention is a double-blind randomized controlled trial with a placebo control group that is matched to the treatment group in all respects except for the treatment. ---------- Frequent Questions and Our Answers ---------------------------------- What is a research design called when neither the participants?Definition. The double-blind design describes an experimental procedure in which neither the participant nor the experimenter are aware of which group (i.e., experimental or control) each participant belongs to.
What do we call the group of participants who receive no treatment?Negative control group: In this type of control group, the participants are not given a treatment. The experimental group can then be compared to the group that did not experience any change or results.
In which type of study nor researcher nor participants are aware in which group the participants are allocated?Answer and Explanation: The studies in which neither the analyst nor the respondents are aware that who is receiving the treatment who is not is known as the double-blind study.
When neither the patients or experimenters are aware of which patients are part of an experimental group or the control group the experiment is called a n?Because both the participants and the experimenters are blind to the condition, this technique is referred to as a double-blind study . (A single-blind study is one in which the participant, but not the experimenter, is blind to the condition.)
