Practice effects on the Wisconsin Card Sorting Test-64 Card version across 12 months.
The Wisconsin Card Sorting Test (WCST: Heaton, Chelune, Talley, Kay, & Curtiss, 1993) is among the most commonly administered measures of executive function. Recently, a short form of the test was developed (WCST-64: Kongs, Thompson, Iverson, & Heaton, 2000), and it affords psychometric properties commensurate with the full version of the test. Yet, similar to other measures of executive function, relatively little is known concerning the effects of repeated administration on the WCST-64. Towards this end, 53 men (age M = 32.38) were administered the WCST-64 twice over 12 months, and scores on several indices improved significantly during this interval. Suggestions concerning the use of these measures in longitudinal research designs and clinical follow-up examinations are offered, and reliable change indices concerning these measures are included.
