简要总结
PTSD Coach is a mobile application (app) that aims to teach individuals self-management strategies for symptoms of Post-traumatic Stress Disorder (PTSD). PTSD is a major public health concern. Although effective treatments exist, affected individuals face many barriers to receiving traditional care. As smartphones are now carried by more than half of the U.S. population, they have the potential to overcome many of these barriers by delivering self-help interventions on apps. Despite PTSD Coach's use of evidence-based cognitive behavioral strategies there is still a need to test the effectiveness of the app in managing PTSD symptoms. This controlled, two-arm, randomized (1:1) trial will evaluate the efficacy, feasibility and acceptability of PTSD Coach to reduce PTSD symptoms in a community sample of trauma survivors with PTSD symptoms. After completing an eligibility phone screen or online screen, individuals who score a 35 or above on the PTSD Checklist (PCL) and consent will complete a baseline assessment and then be randomized to the PTSD Coach app condition or a waitlist control group. Additionally, those assigned to the PTSD Coach intervention will be instructed to download a research version of the app, called PTSD Explorer, that enables passive and objective monitoring of app use. Each individual will be reassessed at post-intervention (3 months) and follow-up (3 months later, or 6 months after completing baseline). The investigators predict that those using the PTSD Coach app will demonstrate a significant and sustained reduction in PTSD symptoms and increase in patient coping self-efficacy compared to the waitlist control group. The investigators will explore if there is a relationship between levels of engagement and PTSD symptom change.

研究组 & 干预措施
PTSD Coach
Subjects assigned to this condition receive information about how to download the research app, PTSD Explorer. This research version of PTSD Coach functions exactly the same, however we have the ability to track individual usage of the app. The app contains contains psycho-education about PTSD and the management of symptoms of PTSD along with activities and techniques to address symptoms. Subjects are told to use the app as much or as little as they want over the next three months.
干预措施: PTSD Coach (Behavioral)

Waitlist Control
Subjects assigned to this condition are told: "You have been randomly assigned to Group 2, the group that does not use the app."
Following their completion of the post-intervention assessment at 3 months, they are told how to access to the publicly available PTSD Coach app in the Apple App Store or Android Play Store, just so that they are made aware of the resources available to them.

结局指标
主要结局
Change in PTSD Symptoms Measured by the Post Traumatic Stress Disorder Checklist (PCL)
时间窗: Baseline to Posttreatment (3 months)
PTSD symptoms were assessed with the PCL-C (Weathers et al., 1993), a 17-item self-report measure of DSM-IV PTSD symptoms with strong psychometric properties (Wilkins, Lang, \& Norman, 2011). Items are rated on how much the symptom bothered the respondent in the past month on a scale ranging from 1 (not at all) to 5 (extremely), with the sum score ranging from 17 to 85 providing a symptom severity rating, with higher ratings indicating more severe PTSD symptoms.
次要结局

- Sustained Change in PTSD Symptoms Measured by the Post Traumatic Stress Disorder Checklist (PCL)(Postreatment to 3-month Follow-up)
- Change in Subject Coping Self-efficacy Measured by a Questionnaire Assessing Confidence in Managing Core Symptoms of PTSD Addressed in the Intervention(Baseline to Posttreatment (3 months))
- Change in Depression Symptoms Measured by the Patient Health Questionnaire (PHQ8)(Baseline to Posttreatment (3 months))
