한글판 단축형 자살 사고 척도의 타당화

초록

Objectives An accurate and easy-to-identify form is needed for the early evaluation of suicidal ideation in high-risk patients. Therefore, this study examined the validity and reliability of a Korean version of the Ultra-Short Suicidal Ideation Scale (K-USSIS). Methods A total of 161 psychiatric university-affiliated general hospital patients completed the K-USSIS. The data were analyzed using correlation, internal consistency, and confirmatory factor analyses. Results First, the scale had good internal consistency with a Cronbach’s α of 0.94. Second, the confirmatory factor analysis demonstrated that the single-factor model had a reasonable fit (comparative fit index=0.99, Tucker–Lewis index=0.98, standardized root mean squared residual= 0.01, and root mean square error of approximation=0.10). Finally, the convergent validity analysis revealed a significant positive correlation with depression, anxiety, and hopelessness. Conclusion The findings suggest that the K-USSIS has good psychometric properties and can serve as a valuable tool for screening for suicidal ideation to ensure early intervention in Korean psychiatric patients.
