The literature demonstrates links between socioenvironmental characteristics, dysregulation of the stress response system, and PTSD, though few studies integrate these factors in one model. In a secondary analysis of cross-sectional data collected by the Survey of the Health of Wisconsin (SHOW), structural equation modeling evaluated the relationships between socioenvironmental stress, cumulative biological risk (CBR), and PTSD symptom severity. The model hypothesized that exposure to socioenvironmental stress was associated with PTSD and that this relationship is mediated by increased CBR. Indices suggest the model provided a good fit to the data and supported socioenvironmental stress and CBR as valid latent constructs. Although the association between CBR and PTSD was not found to be statistically significant in this study, socioenvironmental stress was a significant predictor of PTSD and CBR. Given the role of socioenvironmental factors on CBR and PTSD symptoms, providers need to better assess and incorporate social stressors within evaluation and treatment.

文献证明了社会环境特征、压力反应系统失调和 PTSD 之间的联系，尽管很少有研究将这些因素整合到一个模型中。在对威斯康星州健康调查 (SHOW) 收集的横断面数据进行二次分析时，结构方程模型评估了社会环境压力、累积生物风险 (CBR) 和 PTSD 症状严重程度之间的关系。该模型假设暴露于社会环境压力与 PTSD 相关，并且这种关系是由 CBR 增加介导的。指数表明，该模型很好地拟合了数据，并支持社会环境压力和 CBR 作为有效的潜在结构。尽管在这项研究中没有发现 CBR 和 PTSD 之间的关联具有统计学意义，社会环境压力是 PTSD 和 CBR 的重要预测因素。鉴于社会环境因素对 CBR 和 PTSD 症状的作用，提供者需要更好地评估社会压力源并将其纳入评估和治疗中。
