OBJECTIVES: According to previous findings, stressful life events (SLEs), and its subtypes are associated with depressive symptoms. However, few studies have explored potential models for events and incidental symptoms.
METHODS: The participants (men: 3,966 men; women: 5,709) were recruited from the Cardiovascular and Metabolic Diseases Etiology Research Center. 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). The joint latent space item response models were performed by sex and age group (under 50 vs. 50+ years).
RESULTS: Among the LESs’ item, death/illness of close relatives, legal/sexual difficulties, family relationships, or social relationships shared latent positions with major depressive symptoms regardless of sex or age. We also observed a sex-specific domain; occupational and family-related items.
CONCLUSION: By projecting LES and BDI-II into the same interaction map in each subgroup, we could specify the association between specific LES and depressive symptoms.
