Abstract
OBJECTIVES
According to previous findings, stressful life events (SLEs) and their subtypes are associated with depressive symptoms. However, few studies have explored potential models for these events and incidental symptoms of depression.
METHODS Participants (3,966 men; 5,709 women) were recruited from the Cardiovascular and Metabolic Diseases Etiology Research Center cohort. SLEs were measured using a 47-item Life Experiences Survey (LES) with a standardized protocol. Depressive symptoms were assessed using the Beck Depression Inventory-II (BDI-II). Joint latent space item response models were applied by gender and age group (<50 vs. ≥50 years old).
RESULTS Among the LES items, death or illness of close relatives, legal problems, sexual difficulties, family relationships, and social relationships shared latent positions with major depressive symptoms regardless of gender or age. We also observed a gender-specific domain: occupational and family-related items.
CONCLUSIONS By projecting LES and BDI-II data onto the same interaction map for each subgroup, we could specify the associations between specific LES items and depressive symptoms.

Summary
Korean summary
- 본 연구는 성별, 연령에 따른 생활스트레스 항목과 Beck Depression Inventory-II (BDI-II) 로 측정한 우울증상 사이의 연관성을 Joint Latent space item response model (LSIRM) 방법을 사용하여 탐색하고자 하였다.
- 한국 성인 인구집단 (3,966 남성; 5,709 여성)을 대상으로 연구를 수행한 결과, 생활스트레스 항목 중 가족 혹은 가까운 주변인의 죽음 혹은 질환, 법적인 문제, 성적 어려움, 가족 혹은 사회적 관계는 성별, 연령에 무관하게 우울 증상과 연관성이 있었으며, 직업, 일부 가족 관련 항목에서 성별 특이적인 연관성을 관찰하였다.
Key Message
- In this study, we used a joint latent space item response model (LSIRM) to project stressful life events and depressive symptoms as measured by the Beck Depression Inventory-II (BDI-II) onto an interaction map, which represents the interaction of BDI-II items and underlying traits with each SLE, while accounting for heterogeneity by sex and age group.
- Among the LES items, death/illness of close relatives, legal problems, sexual difficulties, family relationships, and social relationships shared latent positions with major depressive symptoms regardless of sex or age group. But, in occupational and family-related items, sex-specific associations were observed.
