摘要：Access to face-to-face mental health care may be temporarily restricted during pandemics. Remotely administered interventions, such as selfmanagement apps, can increase reach and complement existing services. However, their benefit is uncertain. We investigated whether access to the self-management app PTSD Coach can reduce posttraumatic stress, depressive and somatic symptoms. Method: Participants were adults (n = 179: 164 women, mean age = 42.78 years) who had experienced potentially traumatic events in the past 2 years. Common events were sudden, violent death, physical/sexual assault, and life-threatening illness or injury. We recruited participants from social media ads between May 2019 and June 2020 and randomized them to access to PTSD Coach (n = 89) or waitlist (n = 90). Participants rated symptoms before and after 3 months of app access or waitlist. The primary outcome was posttraumatic stress (PTSD Checklist for DSM-5). Secondary outcomes were depressive symptoms (Patient Health Questionnaire-9) and somatic symptoms (Patient Health Questionnaire-15). Outcomes were analyzed per-protocol with linear mixed-effects models for available baseline (n = 179) and follow-up responses (n = 150). Results: Preliminary results indicate that access to PTSD Coach was associated with reduced posttraumatic stress (B = –7.03, p 0.05). Conclusions: Access to PTSD Coach may confer reductions in psychological symptoms. The Swedish PTSD Coach may complement existing face-to-face services for people who have experienced trauma. We discuss the relevance of self-management apps during the pandemic.
