To examine the clinical validity of the Korean Personality Factor Test(KPFT), this study compared the factor structures of KPFT in psychiatric patient group to normal group. This study also tried to identify the different factors among normal, generalized anxiety disorder, major depression, bipolar disorder manic, somatization disorder and schizophrenia groups, and to investigate the relationships between these factors and symptoms to examine the validity of KPFT in its clinical application. The result of this study was : first, the factors extracted from the patient group was similar to those of the normal group in extracted sequence and factor structure, which suggested this applicability for the patient group. second, the group differences in factor analysis were B, C, N, O, Q1, Q4, EXT, ANX, SUP, IND, CRE factors, and the accuracy rates of classification by discriminant analysis were considerably high in normal group(57.6%), schizophrenia group(46.6%), bipolar disorder manic group(41.6%), and generalized anxiety disorder group(51.2%), and were a relatibly low in major depression group(28.5%) and somatization disorder group(29.7%). The result of this study suggests that the psychiatric symptoms can be understood in terms of the dimensional personality structure of KPFT.
