Abstract

Objectives : Depressive disorder and anxiety disorder frequently co-occur, even at sub-threshold level. This study aims to identify network structure of co-morbid depression and anxiety at symptom level in nonclinical population and to reveal the central symptoms and bridge symptoms of the co-morbidity. Methods : This study was based on 2022 Asan Youth Mental Health Screening. Patient health questionnaire (PHQ-9) and Generalized anxiety disorder scale (GAD-7) were used to assess depressive and anxiety symptoms of 810 young adult participants from community sample. Network structure of co-morbid depressive and anxiety symptoms was estimated by Isingfit model. Results : Depressed mood, Restlessness and Nervousness were the most central symptoms in the network. Bridge symptoms between anxiety and depression were Restlessness and Irritability. Conclusions : This study revealed key central symptoms and bridge symptoms of co-morbid depression and anxiety in nonclinical population and provided potential insight for treatment targets to reduce co-morbidity.

연구목적 우울장애와 불안장애는 흔히 공존하며 임상전단계에서도 흔히 공존한다. 본 연구는 일반인구 집단에서 우울장애와 불안장애가 공존시의 복합 네트워크를 구성하여 중심 증상과 중개 증상을 밝히고자 했다. 방 법 2022년 아산시 청년 정신건강실태조사 데이터를 활용하여 진행하였다. 일반 인구집단 810명의 성인을 대상으로 PHQ-9과 GAD-7을 이용하여 각각 우울과 불안증상의 정도를 측정하였고, 각 증상에 대해 Isingfit model을 기반으로 네트워크 구조를 도출하였다. 주요 증상 및 중개 증상을 찾기 위해 네트워크 지표 중 강도 중심성과 bridge expected influence를 활용하였다. 결 과 우울한 기분, 안절부절 못함과 초조함이 네트워크에서 가장 높은 강도중심성을 보였으며, 불안증상과 우울증상 간의 높은 중개 역할을 하는 증상은 안절부절 못함과 과민성이었다. 결 론 일반 인구집단에서 우울증상과 불안증상이 공존할 때의 중심증 상과 중개증상을 규명하였고 치료적 중재의 목표가 되면 두 질환의 동반이환율을 감소시키는데 기여할 수 있을 것으로 기대된다.
