The Effectiveness of Written Exposure Therapy for PTSD
Sponsor: Peking University
Summary
Study 1: The goal of this study is to use a pilot RCT to assess the effectiveness of Written Exposure Therapy (WET) and a mindfulness-based app (MBA) for managing PTSD and comorbid insomnia in China. The main questions it aims to answer are: 1. Does WET alone reduce PTSD symptoms in Chinese patients with PTSD and subthreshold PTSD? 2. Does the addition of MBA to WET lead to greater reductions in comorbid insomnia symptoms compared to WET alone? 45 participants will be allocated to MCC, WET, and WET+MBA on a 1:1:1 ratio. Researchers will compare WET alone and MCC to see if WET provides benefits in managing PTSD. Researchers will compare WET plus MBA and WET group to see if the integrated MBA treatment provides additional benefits in managing insomnia. Study 2: The study aims to examine the effectiveness of the online revised written exposure therapy (WET-R) for PTSD and subclinical PTSD among Chinese adults with a randomized controlled trial. The study will recruit 90 participants, with 60 randomized to the online WET-R group, and 30 randomized to the minimal contact control (MCC) group. The WET-R intervention consists of 5-7 one to one sessions. The primary outcome PTSD Symptom Scale - Interview for DSM-5 (PSSI-5) will be administered on baseline, post-treatment, 1-month follow-up, 3-month follow-up, and 6-month follow-up assessments.

Interventions
written exposure therapy-revised version
WET-R is a manualized exposure-based therapy program consisting of 5-7 sequential individual sessions. The interval between every 2 consecutive sessions is 0-3 days. There will be 5-7 one to one online sessions in total (only one index trauma will be discussed), and 1-3 weeks to complete. Sessions are scheduled to last for 1 hour in the first session and 50 minutes in other sessions.
minimal contact control
Participants assigned to MCC will be asked to not work with other therapists or seek additional treatment for trauma-related difficulties during the 3-week MCC period. They will be video-called once per week by a therapist to monitor their status and to provide support as needed. The calls will be limited to 10-15 minutes. MCC participants will also be given contact information to use in case of worsening symptoms or increasing distress.
