目的：创伤后应激障碍(PTSD)是一个重大的公共卫生问题。尽管存在有效的治疗方法，但受影响的个人在接受传统护理方面面临许多障碍。近三分之二的美国人口携带智能手机，这为通过应用程序(App)提供自助干预来克服其中许多障碍提供了一个很有前途的新选择。由于针对有创伤后应激障碍症状的创伤幸存者应用程序的研究有限，我们进行了一项针对创伤后应激障碍的自我管理智能手机应用程序--PTSD Coach的可行性、可接受性和潜在疗效的试点试验。方法：有创伤后应激障碍症状的社区幸存者(N=49)被随机分为1个月，接受创伤后应激障碍教练或等待治疗。在基线、状态后和1个月随访时完成自我报告评估。在后条件评估之后，等待名单的参与者被交换接受创伤后应激障碍教练。结果：参与者报告说，他们每周都会使用这款应用程序几次，全天在多个环境中使用，而且几乎没有使用障碍。参与者还报告说，创伤后应激障碍教练的组件有一定的帮助，他们已经从应用程序中学习了管理自己症状的工具和技能。在不同条件下，对PTSD症状改善的效应大小估计是适度的(d=-0.25到-0.33)，但没有统计学意义。结论：研究结果表明，创伤后应激障碍教练是一种可行和可接受的干预措施。关于疗效的研究结果不太清楚，因为这项研究的统计能力很低；然而，效果大小的估计、组内发现的模式和二次分析表明，关于创伤后应激障碍教练的进一步发展和研究是有必要的。
Objective: Posttraumatic stress disorder (PTSD) is a major public health concern. Although effective treatments exist, affected individuals face many barriers to receiving traditional care. Smartphones are carried by nearly 2 thirds of the U.S. population, offering a promising new option to overcome many of these barriers by delivering self-help interventions through applications (apps). As there is limited research on apps for trauma survivors with PTSD symptoms, we conducted a pilot feasibility, acceptability, and potential efficacy trial of PTSD Coach, a self-management smartphone app for PTSD. Method: A community sample of trauma survivors with PTSD symptoms (N = 49) were randomized to 1 month using PTSD Coach or a waitlist condition. Self-report assessments were completed at baseline, postcondition, and 1-month follow-up. Following the postcondition assessment, waitlist participants were crossed-over to receive PTSD Coach. Results: Participants reported using the app several times per week, throughout the day across multiple contexts, and endorsed few barriers to use. Participants also reported that PTSD Coach components were moderately helpful and that they had learned tools and skills from the app to manage their symptoms. Between conditions effect size estimates were modest (d = -0.25 to -0.33) for PTSD symptom improvement, but not statistically significant. Conclusions: Findings suggest that PTSD Coach is a feasible and acceptable intervention. Findings regarding efficacy are less clear as the study suffered from low statistical power; however, effect size estimates, patterns of within group findings, and secondary analyses suggest that further development and research on PTSD Coach is warranted.
