Abstract

Objectives : The purpose of this study was to examine whether the MMPI-2-RF serves as a useful tool to differentiate between the subtypes of high risk of suicide among psychiatric outpatients. Methods : Patients were recruited from the department of psychiatry of university hospital. Participants were diagnosed using DSM-5 criteria by board certified psychiatrists. Their medical records were reviewed retrospectively. And participants were put into 4 groups (Suicide ideation, Suicide attempt, Non-suicidal self-injury, and general psychiatric diagnosis as a control group). For statistical comparison, the MANCOVA with gender as a covariate was used. Results : The results indicated that as previous research with non-clinical sample suggested, psychiatric outpatients with high suicide risk also have significantly higher Emotional/Internalizing Dysfunction, Helplessness/Hopelessness, Suicidal/Death Ideation, Demoralization, Cognitive complaints, Cynicism, Dysfunctional negative thoughts than general psychiatric patients group. But group differences within the high suicide risk patients have not been observed. However, suicide attempt group and NSSI group has higher Behavioral/Externalizing Dysfunction, RC4, AGG than general psychiatric patients group. But there was no difference between suicidal idea group and general psychiatric patients group. Conclusions : There was no group difference observed between all three subtypes, which mean the MMPI2-RF may not be the useful diagnostic tool to navigate high suicide risk subtypes. Even though there was no difference observed in the suicide ideation group, suicide attempt group and NSSI group have higher aggression and externalization. So those indexes could serve as a useful marker to investigate riskiness of suicide related symptoms.

연구목적 본 연구에서는 정신과 외래 환자 중 자살 고위험 집단인 자살 사고, 자살 시도, 비자살적 자해 및 일반 정신과 환자 집단의 감별 시 MMPI-2-RF가 변별 도구로써 활용될 수 있는지 알아보고자 하였다. 방 법 모든 대상자는 한양대학교 구리병원에 정신과적 진료를 내원한 환자로, 정신건강의학과 전문의로부터 DSM-5에 근거한 진단을 받았고, 이들의 의무기록을 후향적으로 검토하여 네 집단(자살 사고, 자살 시도, 비자살적 자해, 통제집단으로 일반 정신과 환자)으로 분류하였다. 총 112예가 분석에 포함되었다. 수집된 자료를 분석하기 위해 기술 통계 분석, 성별을 공변인으로 한 다변량 공분산분석(MANCOVA)를 통해 집단 간 차이를 알아보고자 하였다. 결 과 연구 결과, 비임상군인 대학생을 대상으로 한 기존 선행 연구와 마찬가지로, 임상군인 정신과 외래 내원 환자들 중에서도 자살 고위험군이 저위험군에 비해 높은 정서적/내재화 문제(EID), 무력감/무망감(HLP), 자살/죽음 사고(SUI), 의기소침(RCd), 인지적 증상 호소(COG), 냉소적 태도(RC3), 역기능적 부정 정서(RC7)와 부정적 정서성/신경증(NEGE-r) 점수를 보였다. 하지만 자살에 대한 위험성이 높은 환자들을 자살 사고, 자살 시도, 비자살적 자해를 시도하는 개인들 총 세 집단으로 나누어 분석하였을 때, 세 집단 모두를 변별할 수 있는 변인은 관찰되지 않았다. 다만, 자살 시도 집단 및 비자살적 자해 집단이 일반 정신과 환자 집단에 비해 높은 행동화/외현화(BXD), 반사회적 행동(RC4), 공격성(AGG) 등을 보였으나, 자살 사고 집단과 일반 정신과 환자 집단 사이에는 유의한 차이가 없었다. 결 론 본 연구는 MMPI-2-RF가 임상군인 정신과 외래 내원 환자들 중 자살 위험이 높은 환자들을 자살사고, 자살 시도, 비자살적 자해 세 집단으로 구분했을 때, 이 세 집단을 변별할 수 있는 유용한 진단적 도구로써 기능할 수 있는지 확인해보고자 하였으나, 세 집단 모두를 변별해주는 요인은 관찰되지 않았다. 이에, 세 집단 간변별에는 MMPI-2-RF가 진단적으로 유용하지 않을 것으로 시사된다. 다만, 자살 사고 집단에서는 차이가 나타나지 않았으나 자살 시도 및 비자살적 자해 집단에서는 통제군인 일반 정신과 환자들에 비해 높은 공격성과 행동화가 나타나, 자살 사고가 실제 자살 시도로 이행되는 과정에서 이러한 지표들이 위험성을 판단할 수 있는 조기변별 지표로서 기능할 수 있을 것으로 보인다.
