Test-retest reliability is appropriate for evaluating the stability of a trait over time. This involves administering the same test to the same group of people twice, with a time interval in between, and examining the consistency of their scores. This type of reliability estimate is appropriate when evaluating the reliability of a test that measures a trait that is presumed to be relatively stable over time. Parallel-forms, alternate-forms, and split-half reliability estimates may also be appropriate in certain situations, but they are not specifically designed to evaluate the stability of a trait over time.
