What the trial is, and whether it could suit you
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 PTS
