초록

본 연구는 외상 사건을 경험한 국내 성인의 외상 후 스트레스(Post Traumatic Stress Disorder) 증상과 외상 후 성장(Post Traumatic Growth) 양상을 토대로 잠재계층(latent class)을 도출하고, 각 집단 구분에 영향을 미치는 특성을 탐색하며, 집단에 따른 자기파괴적 행동의 차이를 탐색함으로써, 외상 사건을 경험한 개인에 대해 보다 심층적으로 이해하고자 한다. 이를 위해 본 연구에서는 DSM-5 진단기준에 해당하는 외상 사건을 경험한 국내성인 860명을 대상으로 잠재프로파일분석(Latent Profile Analysis)과 R-3STEP 방식을 이용하였다. 집단 예측 변인으로 개인의 인구사회학적 변인(성별, 연령, 최종 학력, 종교유무, 종교활동 정도, 월 평균 소득)과 사회적 고립, 외상 경험 빈도가 포함되었으며, 종속변인으로 자기파괴적 행동(폭식 정도, 비자살적 자해 유무, 음주의 양, 음주 형태, 음주로 인한 정신 사회적 문제)을 포함하였다. 연구결과 집단은 '저 PTSD/중 PTG집단', '저 PTSD/고 PTG집단', '고 PTSD/고 PTG집단'으로 분류되었다. 또한 성별, 최종학력, 사회적 고립, 외상 노출 빈도가 집단 예측 변인으로 영향을 미치는 것으로 나타났으며, 폭식 정도, 비자살적 자해 유무, 음주 형태, 음주로 인한 정신사회적인 문제에서 집단 간 차이가 있는 것으로 나타났다. 마지막으로 본 연구의 결과를 바탕으로 논의와 시사점을 제시하였다.

Abstract

The present study examined patterns of co-occurrence between DSM-5 posttraumatic stress disorder(PTSD) symptoms and posttraumatic growth(PTG) among Korean populations(n= 860). Latent profile analysis was used to identify subclasses and suggested that the 3-class model fit best: (1) Low PTSD/Mild PTG group (2) Low PTSD/High PTG group; (3) High PTSD/High PTG group. Class membership was predicted by demographic variables, social isolation, and frequency of traumatic experiences. Classes also differed with respect to self-destructive behaviors(binge eating, non-suicidal self-injury, and problem drinking). These findings contribute to future research about the coexisting patterns of PTSD and PTG, and to identify high-risk individuals who suffer from trauma-related problems in clinical practice.
