The present study attempted to replicate the findings of previous factor analytic studies of the Wisconsin Card Sorting Test (WCST) in a homogeneous sample of patients suffering recent cerebrovascular accidents and being treated in a comprehensive inpatient physical rehabilitation program. In addition this study examined the relationship of the WCST to standard measures of functional ability used in many rehabilitation programs. The results confirmed the previously reported three-factor structure and replicated past findings concerning the test's construct validity. A small but significant relationship was noted between the WCST and functional status, though the WCST did not make a unique contribution to the prediction of functional status at discharge. This study highlights the similarities and differences in WCST factor structure in a stroke sample compared to a more general neurological sample and raises questions about the utility of the WCST in stroke rehabilitation.
