the initial testing‚ producing difficulties due to practice effects‚ reactivity‚ or both. Since it has just 20 questions‚ furthermore‚ it is easier for examinees to remember a significant portion of its items and therefore either to remember the answers during the retest or to seek them out during the interval‚ resulting in erroneous score improvements (Yu‚ 2005). As it is impossible to discern the precise influences of any one factor‚ the interpretation of a test-retest coefficient is challenging
