This study sought to understand how PTSD predicts opioid use onset rates and how subsequent exposures to violence also influence this risk following adjudication. Survival analysis was used to examine the moderating role that baseline PTSD status plays for predicting rates of opioid use onset risk following adjudication. Hazard models used to examine the role of time-varying covariates for predicting opioid onset risk following adjudication. PTSD was found to predict significantly greater odds of opioid use initiation. Hazard of introducing opioid use was greater during observation periods in which participants witnessed violence. This effect was greater for PTSD sufferers.

本研究试图了解 PTSD 如何预测阿片类药物的使用发病率，以及随后的暴力暴露如何影响裁决后的这种风险。生存分析用于检查基线 PTSD 状态在预测裁决后阿片类药物使用发病风险率方面的调节作用。用于检查随时间变化的协变量在裁决后预测阿片类药物发作风险的作用的危险模型。发现 PTSD 可以预测阿片类药物开始使用的几率显着增加。在参与者目睹暴力的观察期间，引入阿片类药物的危险更大。对于 PTSD 患者，这种影响更大。
