A-173 Clinical Comparisons of Performance on the Wisconsin Card Sorting Task: Preliminary Findings for an Updated Adult Normative Data

Objective The Wisconsin Card Sorting Test (WCST) is a widely used neuropsychological measure of executive functioning. The purpose of this study is to present clinical comparisons of performance on the WCST among a group of adult patients referred for outpatient neuropsychological evaluation. Method Over two thousand and four hundred patients completed the WCST as part of a comprehensive test battery at an outpatient neuropsychology clinic (Mean age: 55.21 ± 15.39 years; Mean Education: 14.93 ± 2.76 years; 50.9% Female; and 90.2% White). Patients in the sample were referred for evaluations based on the following group classification: General Cognitive Concerns (n = 931); Dementia and Mild Cognitive Disorders (n = 182); Parkinson’s disease and other Movement Disorders (n = 608); Traumatic Brain Injuries/Concussion (n = 161); Primary Brain Tumors (n = 162); among others. Results Descriptive characteristics of raw scores for Total Errors, Perseverative Responses, Perseverative Errors, Nonperseverative Errors, Conceptual Level Responses, and Number of Categories Completed are presented based on clinical population. Group means and standard deviations for scores are presented. The sample are stratified into groups based on age, gender, and education. Base rate comparisons are presented. Conclusions Preliminary findings will contribute to efforts for an updated and demographically corrected normative data for the WCST. Implications are discussed.
