Posttest Only Study with a Control Group

A study type that evaluates a treatment or intervention in one or more samples using a control or comparison group. Standardized assessment measures are administered at post-intervention only to determine outcomes. The study may administer measures at established time points after the conclusion of treatment to determine long-term effects of the intervention. Treatment outcomes for the intervention group(s) are evaluated to determine if the intervention was more effective than services as usual.
