目的：创伤后应激障碍（PTSD）在人群中非常普遍，但相对较少的患者接受治疗。智能手机应用程序（app）可以通过提供健全的心理教育信息和基于证据的认知行为应对工具，帮助解决这一未满足的需求。我们进行了一项随机对照试验，以评估免费、公开的智能手机应用程序（PTSD Coach）对PTSD症状自我管理的功效。方法：120名参与者，平均年龄39岁，主要是女性（69.2%）和白人（66.7%），主要通过在线广告招募，随机分为创伤后应激障碍教练（n = 62）或候补条件（n = 58），为期3个月。在基线、治疗后和治疗后3个月进行PTSD、PTSD症状、应对自我效能、抑郁和心理社会功能的网络自我报告测量。结果：根据意向治疗原则，重复测量方差分析（ANOVAs）显示，在治疗后，PTSD教练参与者在PTSD症状（p = 0.035）、抑郁症状（p = 0.005）和心理社会功能（p = 0.007）方面的改善显著大于等候名单参与者；然而，在治疗后，两种情况的结果没有显著的平均差异。创伤后应激障碍教练参与者达到临床显著的创伤后应激障碍症状改善的比例高于等候名单参与者（p = 0.018）。结论：创伤后应激障碍教练的使用显著改善了创伤后应激障碍症状和其他结果，相对于等候名单条件。鉴于智能手机的无处不在，PTSD Coach可能会为那些没有接受治疗的PTSD患者提供广泛、方便的公共卫生干预。
Objective: Posttraumatic stress disorder (PTSD) is highly prevalent in the population, but relatively few affected individuals receive treatment for it. Smartphone applications (apps) could help address this unmet need by offering sound psychoeducational information and evidence-based cognitive behavioral coping tools. We conducted a randomized controlled trial to assess the efficacy of a free, publicly available smartphone app (PTSD Coach) for self-management of PTSD symptoms. Method: One hundred 20 participants who were an average of 39 years old, mostly women (69.2%) and White (66.7%), recruited primarily through online advertisements, were randomized to either a PTSD Coach (n = 62) or a waitlist condition (n = 58) for 3 months. Web-administered self-report measures of PTSD, PTSD symptom coping self-efficacy, depression, and psychosocial functioning were conducted at baseline, posttreatment, and 3 months following treatment. Results: Following the intent-to-treat principle, repeated-measures analyses of variance (ANOVAs) revealed that at posttreatment, PTSD Coach participants had significantly greater improvements in PTSD symptoms (p = .035), depression symptoms (p = .005), and psychosocial functioning (p = .007) than did waitlist participants; however, at posttreatment, there were no significant mean differences in outcomes between conditions. A greater proportion of PTSD Coach participants achieved clinically significant PTSD symptom improvement (p = .018) than waitlist participants. Conclusion: PTSD Coach use resulted in significantly greater improvements in PTSD symptoms and other outcomes relative to a waitlist condition. Given the ubiquity of smartphones, PTSD Coach may provide a wide-reaching, convenient public health intervention for individuals with PTSD symptoms who are not receiving care.
