The present study examined the efficacy of a brief, written exposure therapy (WET) for posttraumatic stress disorder (PTSD). Participants were 46 adults with a current primary diagnosis of motor vehicle accident-related PTSD. Participants were randomly assigned to either WET or a waitlist (WL) condition. Independent assessments took place at baseline and 6-, 18-, and 30-weeks post baseline (WL condition not assessed at 30 weeks). Participants assigned to WET showed significant reductions in PTSD symptom severity at 6- and 18-week post-baseline, relative to WL participants, with large between-group effect sizes. In addition, significantly fewer WET participants met diagnostic criteria for PTSD at both the 6- and 18-week post-baseline assessments, relative to WL participants. Treatment gains were maintained for the WET participants at the 30-week post baseline assessment. Notably, only 9% of participants dropped out of WET and the WET participants reported a high degree of satisfaction with the treatment. These findings suggest that a brief, written exposure treatment may efficaciously treat PTSD. Future research should examine whether WET is efficacious with other PTSD samples, as well as compare the efficacy of WET with that of evidence-based treatments for PTSD.
本研究考察了一种简短的书面暴露疗法（WET）治疗创伤后应激障碍（PTSD）的疗效。参与者为 46 名当前患有与车祸相关 PTSD 的成年人。参与者被随机分配到 WET 或候补名单（WL）组。基线时以及基线后 6 周、18 周和 30 周进行独立评估（WL 组在 30 周时不评估）。与 WL 组相比，接受 WET 的参与者在基线后 6 周和 18 周时 PTSD 症状严重程度显著降低，组间效应较大。此外，与 WL 组相比，在基线后 6 周和 18 周的评估中，明显更少的 WET 参与者符合 PTSD 的诊断标准。在基线后 30 周的评估中，WET 组的治疗效果得到了维持。值得注意的是，只有 9%的 WET 参与者退出治疗，并且 WET 组对治疗的满意度很高。这些发现表明，简短的书面暴露治疗可能有效地治疗 PTSD。未来的研究应该检验 WET 是否对其他 PTSD 样本有效，以及比较 WET 与 PTSD 的循证治疗的疗效。
