Prolonged Exposure (PE) is an evidenced‐based psychotherapy for posttraumatic stress disorder (PTSD) that is being disseminated nationally within the U.S. Department of Veterans Affairs (VA) with promising initial results. Empirical evidence, however, regarding the effectiveness of PE for treatment of PTSD in military veterans is limited. Building on previous treatment outcome research, the current study investigated the effectiveness of PE in a diverse veteran sample. One‐hundred fifteen veterans were enrolled in PE at an urban VA medical center and its surrounding outpatient clinics. PTSD and depression symptoms as well as quality of life were measured before and after treatment. Several baseline patient characteristics were examined as predictors of treatment response. Eighty‐four participants completed treatment. Participants experienced a 42% reduction in PTSD symptoms, a 31% reduction in depression symptoms, and an increase in quality of life following PE. Veterans not prescribed psychotropic medication reported greater PTSD symptom reduction than veterans prescribed such medication. The implications of these results for treatment programs targeting PTSD in veterans are discussed. 標題:患上PTSD的退役軍接受延展暴露治療的效果 撮要:延展暴露治療(PE)是治療創傷後壓力症(PTSD)的實証為本的心理治療，亦在全國退役軍人事務部中廣泛使用及有初步療效。關於PE在退役軍人的PTSD治療療效的實踐經驗卻是少有的。在前人治療效果研究中抽取概念，我們試圖在今次研究檢查PE在廣泛退伍軍人樣本的效果。樣本是在一個市區VA醫療中心和周邊門診登記接受PE的115名退役軍人，在治療前後會被量度PTSD和抑鬱症狀，及生活質素。我們檢視若干基準病人特點以確定療效的預測因素。總共84名病人完成治療，而他們PTSD在症狀方面有42%減少， 在抑鬱症狀則有31%減退，和PE後生活質素有改進。沒有藥物治療的退役軍人比服藥者有更多PTSD症狀方面的減退。我們也討論本文結果如何對PTSD治療方案方面有所啟發。 标题:患上PTSD的退役军接受延展暴露治疗的效果 撮要:延展暴露治疗(PE)是治疗创伤后压力症(PTSD)的实证为本的心理治疗，亦在全国退役军人事务部中广泛使用及有初步疗效。关于PE在退役军人的PTSD治疗疗效的实践经验却是少有的。在前人治疗效果研究中抽取概念，我们试图在今次研究检查PE在广泛退伍军人样本的效果。样本是在一个市区VA医疗中心和周边门诊登记接受PE的115名退役军人，在治疗前后会被量度PTSD和抑郁症状，及生活质素。我们检视若干基准病人特点以确定疗效的预测因素。总共84名病人完成治疗，而他们PTSD在症状方面有42%减少， 在抑郁症状则有31%减退，和PE后生活质素有改进。没有药物治疗的退役军人比服药者有更多PTSD症状方面的减退。我们也讨论本文结果如何对PTSD治疗方案方面有所启发。
