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.
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).
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.
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.
根据以往的研究结果，生活应激事件（SLEs）及其亚型与抑郁症状有关。然而，很少有研究探讨这些事件和偶发抑郁症状的潜在模型。
参与者（3966 名男性；5709 名女性）来自心血管和代谢疾病病因学研究中心队列。使用标准化方案的 47 项生活经历调查（LES）测量 SLE。使用贝克抑郁量表-II（BDI-II）评估抑郁症状。根据性别和年龄组（<50 岁与≥50 岁）应用联合潜在空间项目反应模型。
在 LES 项目中，无论性别或年龄如何，近亲死亡或患病、法律问题、性困难、家庭关系和社会关系都与重度抑郁症状共享潜在位置。我们还观察到一个特定于性别的领域：职业和家庭相关项目。
通过将 LES 和 BDI-II 数据投射到每个亚组的相同交互图上，我们可以确定特定 LES 项目与抑郁症状之间的关联。
