Description: Quickly assess perseveration and abstract reasoning. The M-WCST is a modification of the original Wisconsin Card Sorting Test that eliminates all cards from the original 128-card deck that share more than one attribute with a stimulus card. The resulting 48-card deck is used along with four stimulus cards to assess perseveration and abstract reasoning with minimal client frustration. Administration and scoring have been simplified -Because the test is simpler than the original version, impaired and elderly adults can more easily understand the directions and complete the task. -Takes less time to administer than the WCST and can be scored in just 2-3 minutes. -Eliminates the illogical possibility of scoring correct responses as perseverative—all perseverative responses are classified as errors. -Four scores are provided: Number of Categories Correct, Number of Perseverative Errors, Number of Total Errors, and Percent of Perseverative Errors. An Executive Function Composite score can also be calculated. -Co-normed with the tests included in the Calibrated Neuropsychological Normative System™ (CNNS™); age-, sex-, and education-based norms are provided. Sensitive to executive deficits and impaired problem solving Highly sensitive to executive dysfunction in schizophrenia, with an effect size (Cohen’s d) of approximately 1.1— a marginal improvement over the original WCST. -Shows excellent sensitivity to impaired problem solving and perseverative reasoning in individuals with many other neurological conditions, including Parkinson’s disease, chronic alcoholism, subcortical vascular dementia, and mild cognitive impairment. -Has been found to detect executive deficits in individuals with bipolar disorder and major depression and in individuals genetically at risk of developing schizophrenia. -The Number of Categories Correct score has been shown to distinguish clinical patients from healthy controls. -The Number of Categories Correct score and the Number of Perseverative Errors score have been found to distinguish patients with Alzheimer’s-type dementia from healthy elderly adults.
