Residential posttraumatic stress disorder (PTSD) research in military samples generally shows that in aggregate, PTSD symptoms significantly improve over the course of treatment but can remain at elevated levels following treatment. Identifying individuals who respond to residential treatment versus those who do not, including those who worsen, is critical given the extensive resources required for such programs. This study examined predictors of treatment response among 282 male service members who received treatment in a U.S. Department of Defense residential PTSD program. Using established criteria, service members were classified as improved, indeterminate (referent), or worsened in terms of self-reported PTSD symptoms. Multinomial logistic regression results showed that for PTSD symptoms, higher levels of pretreatment PTSD symptom severity were associated with significantly lower odds of being in the improved group, adjusted odds ratio (aOR) = 0.955, p = .018. In addition, service members who completed treatment were significantly more likely to be in the improved group, aOR = 2.488, p = .048. Longer average pretreatment nightly sleep duration, aOR = 1.157, p = .035, and more severe pretreatment depressive symptoms, aOR = 1.109, p = .014, were associated with significantly higher odds of being in the improved group. These findings reveal clinical characteristics better suited for residential PTSD treatment and highlight implications for comorbid conditions.

心理合并症：患有创伤后应激障碍的美国服役人员住院治疗反应的预测因素

驻地创伤后应激障碍 (PTSD) 对军人样本的研究通常表明，总体而言，PTSD 症状在治疗过程中显着改善，但在治疗后可能会保持在较高水平。鉴于此类计划需要大量资源，确定对住院治疗有反应的人与没有反应的人（包括病情恶化的人）至关重要。这项研究检查了 282 名在美国国防部住宅 PTSD 计划中接受治疗的男性服务人员的治疗反应预测因子。使用既定标准，根据自我报告的 PTSD 症状，服役人员被分类为改善、不确定（参照）或恶化。多项逻辑回归结果显示，对于 PTSD 症状，或) = 0.955，p = .018。此外，完成治疗的现役军人更有可能属于改善组，OR = 2.488，p = .048。更长的治疗前平均每晚睡眠时间 (a OR = 1.157, p = .035) 和更严重的治疗前抑郁症状 (a OR = 1.109, p = .014) 与明显更高的改善组几率相关。这些发现揭示了更适合住院 PTSD 治疗的临床特征，并突出了对合并症的影响。
