- Abstract
This study examined test-retest reliabilities and (predictors of) practice effects of the widely used computerized neuropsychological battery CNS Vital Signs. The sample consisted of 158 Dutch healthy adults. At 3 and 12 months follow-up, 131 and 77 participants were retested. Results revealed low to high test-retest reliability coefficients for CNS VS' test and domain scores. Participants scored significantly higher on the domains of Cognitive Flexibility, Processing Speed, and Reaction Time at the 3-month retest. No significant differences in performance were found over the second interval. Age, education, and retest-interval were not significantly associated with practice effects. These results highlight the need for methods that evaluate performance over time while accounting for imperfect test-retest reliabilities and practice effects. We provided RCI-formulae for determining reliable change, which may be possible solution for future work facing the methodological issues of retesting.
