초록
본 연구는 정신질환으로 인한 주요 증상과 기능상의 어려움을 주관적으로 보고하는 행동 및 증상 평가척도(BASIS-32)를 타당화하고자 190명의 환자를 대상으로 척도의 심리적 속성을 측정하였다. 측정결과 척도의 내적 일치도는 .93, 문항-총점간 상관은 .49에서 .72의 범위, 검사-재검사 신뢰도도 양호하게 나타났다. 척도의 요인분석 결과 5요인이 추출되었고, 각각 대인관계문제, 우울 및 불안, 충동적 및 중독행동, 일상생활과 역할기능, 정신병적 증상으로 명명되었다. 척도 전체 및 하위 요인들은 GHQ 및 SCL-90-R 증상차원과 유의한 상관을 나타내 동시타당도를 보여주었고, 또한 입원형태에 따른 변별타당도도 확인되었다. 이는 정신건강서비스 영역에서 행동 및 증상평가에 관한 척도의 활용가능성을 시사한다. 연구의 제한점과 추후 정신건강 및 재활서비스 영역에서의 활용을 논의하였다.
Abstract
BASIS-32 is one of the measurement derived from patient perspectives and covers the major symptoms and functioning difficulties experienced as a result of mental illness. This study was conducted to verify the reliability and validity for the BASIS-32 designed to assess the patient's self-ratings, which could presented different way from clinician. The research packet was administerd to 190 psychiatric patients: BASIS-32, GHQ, SCL-90-R. BASIS-32's reliability was tested by internal consistency, item-total correlation and test-retest reliability. Its validity was tested by factor analysis, concurrent validity, and discriminant validity. BASIS-32 was reliable in terms of internal consistency, test-retest reliability, and corrected item -total correlation r ranged from .49 to .72. The exploratory factor analysis revealed that BASIS-32 had 5 factors. In addition, estimates of validity of BASIS-32 were established with the criterion measures in conceptually expected ways. Correlations between BASIS-32 and GHQ, symptom subscales of SCL-90-R showed sufficient concurrent validity. These results offer the reliability and validity for BASIS-32. Using BASIS-32 assessed patient's subjective clinical symptoms and difficulties, more comprehensive information could be obtained. The implications and limitations of this study were discussed, and future directions of study were suggested.
