Abstract

This study was investigated about the characteristics of intellectual functions among patients with anxiety, depressive and psychotic disorder on the Korean-Wechsler Adult Intelligence Scale (K-WAIS). The participants were 47 patients with anxiety disorder, 56 patients with depressive disorder, and 62 patients with psychotic disorder. The data were statistically analyzed using multivariate analysis of covariance (MANCOVA) controlling for age and educational level. It was found that the anxiety disorder group acquired significantly higher scores in digit span subtest than the depressive disorder and psychotic disorder groups. The psychotic disorder group acquired significantly lower scores in arithmetic subtest, performance IQ, Freedom from Distractibility factor than the anxiety and depressive disorder groups. Moreover, the psychotic disorder group scored significantly lower in several subtests (comprehension, picture arrangement, object assembly, and digit symbol), verbal and full scale IQ, and perceptual organization factor than the anxiety disorder group. The result suggests that the three clinical groups are differential differences in terms of intellectual abilities. It implicates the probability that it would reflect the differences of functional level in everyday life in each group. (Korean J Str Res 2010;18:353∼362)
