D) Test retest reliability

Question

Quizplus · Accepted Answer

The psychologist is trying to establish behavioral validation by observing the students' signs of anxiety before giving a talk. This would help validate the new measure of stage fright and its ability to predict actual behavior. Internal consistency and test-retest reliability would involve administering the test multiple times to the same group of individuals. Discriminant validity would involve demonstrating that the measure is distinct from other measures of anxiety or similar constructs. These are not relevant to the current situation.
