초록

본 연구는 정신분열병 환자의 인지적 병식과 임상적 병식의 관련성과 병식과 신경심리 기능 및 정신분열병 증상 사이의 관련성을 알아보고자 하였다. DSM-IV에 의해 정신분열병으로 진단된 환자 50명이 연구에 참여하였다. 인지적 병식과 임상적병식의 평가에는 Beck Cognitive Insight Scale (BCIS)과 Scale to Assess Unawareness of Mental Disorder (SUMD)가 사용되었다. 정신분열병 환자의 전두엽 기능, 특히 실행기능을 평가하기 위해 Wisconsin Card Sorting Test (WCST), Controlled Oral Word Association Test (COWA), Trail Making Test (TMT)와 d2 검사가 실시되었으며, K-WAIS 단축형을 사용하여 지능지수를 추정하였다. 정신분열병 증상의 평가에는 The Positive and Negative Syndrome Scale (PANSS)이 사용되었다. 연구 결과, BCIS의 두 하위척도인 자기-반추 척도 (self-reflectiveness)와 자기-확신 척도 (self-confidence)는 비교적 높은 문항내적 일치도와 검사-재검사 신뢰도를 보였다. 또한 BCIS와 SUMD는 유의한 상관을 보였다. BCIS의 자기-반추 척도는 TMT, B형의 반응시간과 유의한 부적 상관을 보인 한편 자기-확신 척도는 COWA의 철자반응수 및 d2 검사의 주의집중 지표와 유의한 정적 상관을 보였다. 이에 덧붙여서 자기-확신 척도는 추정된 지능지수와도 유의한 정적 상관을 보였다. SUMD와 TMT, A형의 반응시간 사이에 유의한 상관이 관찰되었다. BCIS와 SUMD 모두 PANSS로 측정한 일반정신병리 점수와 유의한 상관을 보였다. 연구 결과는 BCIS가 정신분열병 환자의 병식의 평가에 신뢰롭고 타당한 검사라는 것을 보여주었다. 이에 덧붙여서 비록 인지적 병식과 임상적 병식서로 무관하지는 않지만 각각 다른 인지 기능과 관련되어 있다는 것을 보여주었다.

Abstract

This study has attempted to investigate the cognitive insight in schizophrenic patients. Specifically this study examined the relationships between cognitive and clinical insight, and between cognitive/clinical insight and neuropsychological functions in schizophrenic patients. For the measurement of cognitive and clinical insight, Beck Cognitive Insight Scale (BCIS) and Scale to Assess Unawareness of Mental Disorder (SUMD) were administered, respectively. The frontal functions were evaluated by Wisconsin Card Sorting test (WCST), Controlled Oral Word Association Test (COWA), Trail Making Test (TMT) and d2 test. The schizophrenic symptoms were measured by The Positive and Negative Syndrome Scale (PANSS), and K-WAIS was administered to measure IQ. Fifty schizophrenic patients participated in this study. The results showed a significant correlation between BCIS and SUMD. There were associations between self-reflectiveness subscale of BCIS and TMT, part B response time, between self-confidence subscale of BCIS and COWA (letter)/concentration index of d2 test/ estimated IQ, and between SUMD and TMT, part A response time. In addition, both BCIS and SUMD were significantly associated with general pathology of PANSS. All of these results indicate that BCIS is a reliable and valid tool for the measurement of insight of schizophrenic patients, and although cognitive and clinical insight share common factors but seem to be related to the different cognitive functions.
