What is the purpose of a wait list control group?
This control group serves as an untreated comparison group during the study, but eventually goes on to receive treatment at a later date. Wait list control groups are often used when it would be unethical to deny participants access to treatment, provided the wait is still shorter than that for routine services.
What is a waitlist study?
a group of research participants who receive the same intervention or treatment as those in the experimental group but at a later time.
What is randomized waitlist control design?
Waitlist control (WLC) designs are commonly used in these areas and variations of these designs contain a fundamental characteristic that can be improved through adaptation. WLC designs are longitudinal randomized clinical trials that offer all participants access to the investigational intervention [3,4].
What is a wait list design?

What is pre test design?
A pretest posttest design is an experiment where measurements are taken both before and after a treatment. The design means that you are able to see the effects of some type of treatment on a group. Pretest posttest designs may be quasi-experimental, which means that participants are not assigned randomly.

What is the purpose of a wait list in an experiment?
By serving as a comparison group, researchers are able to isolate the independent variable and look at the impact it had.
