: There is a need for accessible interventions in the aftermath of traumatic events with documented efficacy for preventing or reducing negative mental health consequences. The PTSD Coach is a mobile app that has shown to be effective in reducing symptoms of posttraumatic stress (PTSS). : The purpose of the current study was to evaluate the user satisfaction, perceived helpfulness and potential reductions of PTSS and symptoms of depression among participants using the Swedish version of the PTSD Coach. : This was an uncontrolled pre-test post-test open trial including participants recruited from the community via advertisement and from an ongoing observational study who had experienced a potentially traumatic event in the last five years. Participants had access to the Swedish PTSD Coach app for four weeks. : Eleven participants (mean age = 38.6, female = 8) completed the study. Nine of the participants met criteria for full or partial PTSD. Results from the PTSD Coach Survey indicated that participants found the app slightly to moderately helpful and were slightly to moderately satisfied with the app. Nominal but not statistically significant reductions of medium effect sizes in PTSS (PCL-5) and depression (PHQ-9) from pre- to post-assessment were found. In interviews, participants indicated that they found elements such as learning about PTSD, breathing exercises and monitoring symptoms helpful in managing symptoms. However, several participants indicated that they had not used the app as much as they had intended to. Participants also had suggestions for improvements such as enhanced app structure and better guidance regarding how to use the app. : The perceived helpfulness and user satisfaction were slightly lower compared to research on the original version of the app. Experiences from the study are discussed and a future controlled study of the Swedish version of the PTSD Coach is suggested.
在创伤事件发生后，需要有可及的干预措施，且要有已被证实的预防或减少负面心理健康后果的功效。创伤后应激障碍指导（PTSD Coach）是一款移动应用程序，已被证明能有效减轻创伤后应激症状（PTSS）。本研究的目的是评估使用瑞典语版PTSD Coach的参与者的用户满意度、感知到的帮助程度以及PTSS和抑郁症状的潜在减轻情况。这是一项非对照的前测后测开放性试验，参与者通过广告从社区招募，以及从一项正在进行的观察性研究中招募，这些参与者在过去五年中经历了潜在的创伤事件。参与者可以使用瑞典语PTSD Coach应用程序四周。11名参与者（平均年龄 = 38.6岁，女性 = 8名）完成了研究。其中9名参与者符合全部或部分创伤后应激障碍的标准。PTSD Coach调查结果表明，参与者认为该应用程序有一定到中等程度的帮助，并且对该应用程序有一定到中等程度的满意度。从评估前到评估后，发现PTSS（PCL - 5）和抑郁（PHQ - 9）的中等效应量有名义上但无统计学意义的降低。在访谈中，参与者表示他们发现诸如了解创伤后应激障碍、呼吸练习和症状监测等内容对管理症状有帮助。然而，几名参与者表示他们没有像预期的那样频繁使用该应用程序。参与者还提出了改进建议，如增强应用程序结构以及关于如何使用该应用程序的更好指导。与对该应用程序原始版本的研究相比，感知到的帮助程度和用户满意度略低。讨论了该研究的经验，并建议对瑞典语版PTSD Coach进行未来的对照研究。
