Posttraumatic stress disorder (PTSD) and problem drinking are common and often co-occurring sequelae experienced by women survivors of adult sexual assault, yet it remains unclear whether survivors drink to cope with PTSD symptoms or whether PTSD symptoms are exacerbated by drinking. Thus, we used a cross-lagged panel design with a large (N=555), ethnically diverse sample of women assault survivors to determine whether PTSD prospectively led to problem drinking or vice versa. We also examined whether cumulative sexual victimization experiences related to greater PTSD and problem drinking. Structural equation modeling revealed that child sexual abuse was associated with greater symptoms of PTSD and problem drinking and intervening sexual victimization was associated with greater symptoms of PTSD and problem drinking 1 year later. We found no evidence, however, that PTSD directly influenced problem drinking over the long term, or vice versa. Rather, experiencing revictimization during the study predicted survivors' prospective PTSD and problem drinking symptoms. Implications and recommendations for future research are discussed.
创伤后应激障碍（PTSD）和问题饮酒是成年性侵犯女性幸存者常见且常同时发生的后遗症，但目前尚不清楚幸存者是通过饮酒来应对 PTSD 症状，还是饮酒会加剧 PTSD 症状。因此，我们使用了具有大样本（N=555）和种族多样性的女性性侵犯幸存者的交叉滞后面板设计，以确定 PTSD 是否会前瞻性地导致问题饮酒，或者反之亦然。我们还研究了累积性性受害经历是否与 PTSD 和问题饮酒的严重程度有关。结构方程模型显示，儿童性虐待与 PTSD 和问题饮酒症状的严重程度相关，而中间性受害与 1 年后 PTSD 和问题饮酒症状的严重程度相关。然而，我们没有发现 PTSD 直接长期影响问题饮酒，或者反之亦然的证据。相反，在研究期间经历再受害预测了幸存者的前瞻性 PTSD 和问题饮酒症状。讨论了对未来研究的意义和建议。
