Abstract
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.
Conclusions 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.
