Quizplus · Accepted Answer

A waiting list control group is typically used in studies evaluating the effectiveness of a new therapy or intervention. This is because participants are randomly assigned to either receive the therapy immediately or to be placed on a waiting list and receive the therapy at a later time. This allows for comparisons between those who receive the therapy and those who do not, and controls for any potential confounding variables. In the case of the other answer choices, a waiting list control group is less relevant or applicable.
