Aims:
To analyze the validity of the single deck 64-card Wisconsin Card Sorting Test (WCST-64) compared to the standard version (WCST-128), and to study the sensibility of both versions to identify changes over time in patients with traumatic brain injury (TBI).
Patients And Methods:
The WCST was administered twice across a 6-month period to a sample of 50 patients with TBI. Pearson correlation coefficients were calculated to examine bivariate associations between WCST-128 scores and the corresponding WCST-64 scores at inclusion and at follow-up. Agreement in classification of impairment (z = -1) or normal performance was calculated for the two tests (kappa). Significant change over time was also analyzed for both versions of the test (paired-samples t test).
Results:
The results revealed positive and significant correlations between both measures as well as a significant agreement in the classification of patients as having deficits or not. Moreover, the WCST-128 and the WCST-64 showed similar ability to identify changes over time.
Conclusions:
Our findings showed strong associations between scores derived from the two test and support the comparability of both versions when analyzing cross-sectional or longitudinal data. The findings support the use of the WCST-64 in evaluations of executive deficits of patients with moderate and severe TBI.
