Question

Quizplus · Accepted Answer

One of the primary goals in designing psychotherapy outcome experiments is to have high levels of both internal and external validity. Internal validity refers to the extent to which the experimental design and procedures ensure that changes in the dependent variable (e.g. mental health symptoms) are actually due to the independent variable (e.g. psychotherapy) rather than extraneous factors. External validity refers to the extent to which the results of the experiment can be generalized to other populations and settings beyond the study sample and context. It is important to have both high levels of internal and external validity in order for the study to be useful and applicable to the broader population of interest.
