초록

본 연구에서는 최근 새롭게 개정된 K-WAIS-IV를 통해 만성 조현병 환자 집단의 인지기능과 심리-사회적 기능 간 관련성을 파악하고자 하였다. 이를 위해 만성 조현병 환자 40명을 대상으로 한국판 웩슬러 성인용 지능 검사(K-WAIS-IV), 간편 정신장애 평정 척도(BPRS), 독립생활기술 척도(ILSS), 사회적 행동 척도(SBS), 한국판 세계보건기구 삶의 질 단축형 척도(WHOQOL-BREF)를 사용하여 측정한 결과를 토대로 인지기능과 심리-사회적 기능의 관련성을 분석하였다. 연구 결과, 성별, 연령과 같은 인구통계학적 특성 및 정신병리의 증상 심각도를통제한 경우에도 K-WAIS-IV의 토막짜기 소검사는 독립생활 기술의 집안정리 영역, 산수와 이해 소검사는 교통 활용 영역과 상관이 유의하였다. 또한 공통성, 이해, 순서화 소검사 및 처리속도 지표는 사회적 행동의 언어 영역, 어휘, 산수, 순서화 소검사는 대화내용 영역과 상관이 유의하였다. 나아가 동형찾기 소검사는 신체 영역에 대한 삶의 질과 상관이 유의하였다. 이러한 결과는 신경인지기능이 인구통계학적특성이나 정신병리의 증상 심각도를 통제하더라도 심리사회적 기능과 밀접한 관련이 있으며 개별적인 심리사회적 기능과 관련이 있는 인지기능에 차이가 있음을 시사한다.

Abstract

The current study was conducted to investigate the relationship between cognitive function and psycho-social function in chronic schizophrenia patients using the recently revised K-WAIS-IV. K-WAIS-IV, BPRS, ILSS, SBS and WHOQOL-BREF was administered to 40 patients diagnosed with chronic schizophrenia. All scores were analyzed. In a partial correlation analysis, the results showed that even controlling for sex, age, and severity of psychopathology, the Block Design (BD) subtest was significantly correlated with the care of personal possessions in independent living skills and Arithmetic(AR) and Comprehension (CO) subtests were significantly correlated with the transportation in independent living skills. In addition, Similarity (SI), CO, and Letter-Number sequencing (LN) subtests, as well as Processing Speed Index (PSI) were significantly correlated with the language ability in social behavior. Moreover Vocabulary (VC), AR and LN subtests were significantly correlated with the contents of conversation in social behavior. In addition, Symbol Search (SS) were significantly correlated with the physical domain of quality of life. These findings suggest that there is a strong association between each cognitive function and psychosocial function, regardless of the severity of psychopathology or demographic characteristics.
