Repeated attentional and executive testing generally resulted in a practice effect except when using alternate forms, with time-derived scores showing the best test-retest reliability.
Observational (n=37)
Many commonly used attentional and executive neuropsychological tests are subject to practice effects and have variable test-retest reliability, with time-derived scores generally being the most reliable.
There is a lack of data about the practice effect and test-retest reliability (TRR) on many attentional and executive tests in neuropsychology. In this study, 37 subjects aged 52 to 80 were tested three times with an inter-assessment interval of 14 days. The battery included the Rey Auditory Verbal Learning Test, the Stroop interference test, the Letter-Number Sequencing test, Wechsler Adult Intelligence Scale-III (WAIS-III), the Ruff 2 and 7 Selective Attention Test, the Tower of London, the Verbal Fluency test, and simple, choice, and sequential reaction time tests. The results showed that tasks were generally subject to a practice effect, except for those with alternate forms. In all tests, there were a number of scores demonstrating good TRR, but others, although largely used in clinical practice, failed to reach acceptable TRR standards. Usually, time derived scores were associated with the best TRR.
Lemay et al. (Thu,) reported a observational. Repeated attentional and executive testing was evaluated on Practice effect and test-retest reliability (TRR). Repeated attentional and executive testing generally resulted in a practice effect except when using alternate forms, with time-derived scores showing the best test-retest reliability.
