Abstract

Objectives : This study aimed to examine the mediating effect of sleep quality and interpretation bias for ambiguity in the relationship between hopelessness and suicidal ideation in psychiatric patients. Methods : A total of 231 psychiatric outpatients and inpatients completed the Beck Hopelessness Scale, Pittsburgh Sleep Quality Index, Ambiguous/Unambiguous Situations Diary-Extended Version, and Ultra-Short Suicidal Ideation Scale. Data analysis was conducted using regression analyses and bootstrap sampling. Results : The results of this study showed that hopelessness had a direct effect on suicidal ideation, and that sleep quality and interpretation bias for ambiguity mediated the association between hopelessness and suicidal ideation. Moreover, there was a significant double mediating effect of sleep quality and interpretation bias for ambiguity on the relationship between hopelessness and suicidal ideation. Conclusions : These results suggest that it is important to consider both sleep quality and interpretation bias for ambiguity to prevent hopelessness from leading to suicidal idea. These results suggest that considering both sleep quality and interpretation bias for ambiguity may be important in preventing hopelessness from leading to suicidal ideation.

연구목적 본 연구는 정신건강의학과 환자의 절망감이 자살사고에 미치는 영향에서 수면의 질과 모호함에 대한 해석 편향의 매개효과를 확인하고자 하였다. 방 법 한양대학교 구리병원 정신건강의학과의 외래 환자와 입원 환자를 대상으로 축적된 자료를 사용하였으며, 측정 도구로는 벡 절망 척도(Beck Hopelessness Scale), 피츠버그 수면의 질 척도(Pittsburgh Sleep Quality Index), 모호한 상황에서의 시나리오 척도(Ambiguous/Unambiguous Situations Diary-Extended Version, AUSD-EX), Ultra-Short Suicidal Ideation Scale이 사용되었다. 231명의 자료를 기초로 SPSS 25.0과 SPSS Macro를 사용하여 상관분석과 Bootstrapping 기법을 이용한 회귀분석을 실시하였다. 결 과 연구 결과, 절망감과 자살사고의 관계에서 수면의 질과 모호함에 대한 해석 편향의 이중 매개효과가 유의하게 나타났다. 결 론 본 연구는 절망감이 낮은 수면의 질과 모호함에 대한 해석 편향을 거쳐 자살사고에 순차적으로 영향을 미친다는 점을 확인하였다. 이러한 결과는 정신건강의학과 환자에서 절망감이 자살사고로 이어지는 것을 예방함에 있어 낮은 수면의 질과 모호함에 대한 해석 편향을 개선하는 것이 필요함을 시사한다.
