Quizplus · Accepted Answer

Dr. Valencia is comparing the scores of the same participants on two different occasions, which is a test of the measure's consistency over time, also known as test-retest reliability. Option A, interrater reliability, is not relevant since Dr. Valencia is not comparing ratings from different raters. Option B, internal reliability, refers to the consistency of responses within the same test and typically involves calculating Cronbach's alpha or similar statistics. Option D, construct reliability, is not a recognized term in psychometrics.
