Alcohol use is common following traumatic military deployment experiences. What is less clear is why, and for whom, particular deployment experiences lead to alcohol use.
The current study explored associations between deployment stressors (Warfare, Military Sexual Trauma, and Concerns about Life and Family Disruptions-"Life Disruptions"), PTSD (PCL-5), and alcohol use (CAGE) post-deployment, stratified by gender among 2344 male and female veterans (1137 men; Mage = 35). Conditional process analyses examined the indirect effect of traumatic deployment experiences on alcohol use, via PTSD symptom severity, with Life Disruptions as a moderator.
More severe Warfare and military sexual trauma (MST) were associated with greater PTSD symptom severity, which was associated with higher problematic alcohol use. PTSD symptom severity accounted for the associations between trauma type (i.e., MST or Warfare) and alcohol use. Among women, but not men, Life Disruptions moderated the associations between trauma type (i.e., MST, Warfare) and PTSD symptom severity, such that elevated Life Disruptions amplified the associations between trauma type and PTSD symptom severity. Moderated mediation was significant for MST among women, indicating that the strength of the indirect effect (MST ➔ PTSD ➔ problematic alcohol use) was moderated by Life Disruptions; problematic alcohol use was highest for women with greater PTSD symptom severity following exposure to more severe Life Disruptions and MST (Est. = 0.0007, SE = 0.0001, CI = 0.0002 to 0.0013).
Taken together, alcohol use following potentially traumatic deployment experiences can be understood by considering PTSD symptom severity, gender, and Life Disruptions.
创伤性军事部署经历后，饮酒较为常见。但尚不清楚的是，哪些特定的部署经历会导致某些人饮酒，以及为什么会导致某些人饮酒。
本研究探讨了在 2344 名男性和女性退伍军人（1137 名男性；平均年龄=35 岁）中，根据性别分层，创伤性部署经历（战争、军事性创伤和对生活及家庭干扰的担忧-“生活干扰”）、创伤后应激障碍（PCL-5）与部署后饮酒（CAGE）之间的关联。条件过程分析检验了通过 PTSD 症状严重程度，生活干扰作为调节因素，对创伤性部署经历与酒精使用之间的间接效应。
更严重的战争和军事性创伤（MST）与 PTSD 症状严重程度相关，而 PTSD 症状严重程度与更高的酒精使用问题相关。PTSD 症状严重程度解释了创伤类型（即 MST 或战争）与酒精使用之间的关联。在女性中，但在男性中，生活干扰调节了创伤类型（即 MST、战争）与 PTSD 症状严重程度之间的关联，即生活干扰的增加放大了创伤类型与 PTSD 症状严重程度之间的关联。对于女性，MST 的调节性中介作用显著，表明生活干扰调节了创伤类型（MST→PTSD→酒精使用问题）的间接效应强度；在经历更严重的生活干扰和 MST 后，PTSD 症状严重程度较高的女性，酒精使用问题最高（估计值=0.0007，SE=0.0001，CI=0.0002 至 0.0013）。
总的来说，通过考虑 PTSD 症状严重程度、性别和生活干扰，可以理解创伤性部署经历后发生的饮酒问题。
