양극성 조증에서 정신병 유무에 따른 로샤 과제의 지각-조직화 특성: 조현병과의 비교

Abstract

Objectives : Recent reports have consistently demonstrated Rorschach-related perceptual-organizational deficits in patients with schizophrenia, but little is known about manic patients with bipolar disorder. We investigated the perceptual-organization characteristics of the Rorschach task in patients with bipolar mania with or without psychotic features in comparison to schizophrenia. Methods : The Rorschach task and Korean-Wechsler Adult Intelligence Scale (K-WAIS) were performed to measure perceptual-organization capacities with 46 inpatients with bipolar mania (psychotic : 27, nonpsychotic : 19) and 25 inpatients with schizophrenia. Results : When compared among the 3 groups, patients with schizophrenia produced significantly more uncommon detail (Dd) responses than patients with bipolar mania with or without psychotic features. But most of variables were not significantly different in performance of the Rorschach task (ideation, cognitive mediation, information processing) and visuospatial organization cognitive tests (K-WAIS : picture completion, picture arrangement, and block design). In patients with bipolar mania, the significant correlation of the some Rorschach variables (Conventional Form : X+%, Active Human Movement : Ma, Processing Efficiency : Zf, Synthesized Developmental quality : DQ+) with visuospatial organization tests performance was found. Conclusion : We didn’t find the significant perceptual-organizational characteristic differences between bipolar mania and schizophrenia, regardless of presence of psychotic features. These results suggest the possibility that even if nonpsychotic bipolar mania has similar perceptual-organization characteristics like psychotic bipolar mania and schizophrenia, but further investigation will be needed.
