Administering multiple pretests allows us to assess whether participants are already undergoing a change process before treatment. For example, if participants are already experiencing a positive change between the first and second pretest, this may confound the results of the intervention. Therefore, a multiple pretest design enables researchers to identify any early changes and adjust for them in their analyses.
