The relationship between measures of psychopathology, intelligence, and memory among adults seen for psychoeducational assessment

This study assessed the relationship between symptoms of psychopathology and cognitive functioning in clients completing comprehensive psychoeducational assessments at a university-based outpatient mental health clinic. Seventy clients (36 women, 34 men, mean age = 28.8) completed the Wechsler Memory Scale - Third Edition (WMS-III), Wechsler Adult Intelligence Scale - Third Edition (WAIS-III), and Minnesota Multiphasic Personality Inventory - Second Edition (MMPI-2). Partial correlations between the MMPI-2 clinical scales, WMS-III Index scores, WAIS-III Index scores, and WAIS-III IQ scores were not significant. Memory and Intelligence scores for clients with comorbid symptoms of depression and anxiety were comparable to scores for clients without comorbid symptomatology. Psychopathology factors accounted for 22% of the variance in the WAIS-III Full Scale IQ and 6.5% of the variance in the WMS-III General Memory Index. The results suggest that psychopathology as measured by the MMPI-2 may be minimally associated with intelligence and memory test performance in adults seen for psychoeducational assessment.
