Eleven Vietnam veterans with war-related posttraumatic stress disorder (PTSD) were randomly assigned to 10 sessions of either virtual reality exposure (VRE) therapy within a computer-generated virtual Vietnam environment or present-centered therapy (PCT) that avoided traumatic content and utilized a problem-solving approach. Participants were assessed at pretreatment, posttreatment, and 6 months posttreatment by an independent assessor blind to treatment condition. Nine participants completed treatment with one dropout per condition. No significant differences emerged between treatments, likely due to insufficient power. Although comparison of mean changes in PTSD symptoms for the VRE and PCT conditions yielded a moderate effect size (d = 0.56) in favor of VRE at 6 months posttreatment, changes in PTSD scores were more variable, and therefore less reliable, within the VRE condition. The utility of VRE with older veterans with PTSD is discussed.
11 名患有与战争相关的创伤后应激障碍（PTSD）的越南退伍军人被随机分配到计算机生成的虚拟越南环境中的虚拟现实暴露（VRE）治疗或避免创伤内容并采用解决问题方法的以当下为中心的治疗（PCT）的 10 个疗程中。参与者在治疗前、治疗后和治疗后 6 个月由独立评估者进行评估，评估者对治疗条件不知情。9 名参与者完成了治疗，每个条件各有 1 名参与者退出。由于功效不足，两种治疗方法之间没有出现显著差异。尽管 VRE 和 PCT 条件下 PTSD 症状的平均变化比较产生了有利于 VRE 的中等治疗效果（d = 0.56），但在 VRE 条件下，PTSD 评分的变化更加多变，因此不太可靠。讨论了 VRE 在患有 PTSD 的老年退伍军人中的应用。
