Description of intervention(s) / exposure
Internet-based intervention is to be used with a multimodal program “My trauma recovery”, which provides education information about Posttraumatic Stress Disorder and helps users to increase their coping skills and self-efficacy through interactive exercises with feedbacks. The intervention lasts four weeks. Participants are required to use the program at least three times per week with a minimum usage time of 30 minutes per time. The program will provide all participants’ usage information, including login and logout time, time spent on each module and so on.

Comparator / control treatment
The scientific goal is to conduct a comprehensive randomized-controlled trial of internet-based treatment of PTSD for Chinese patients. Half of the sample will be randomly allocated to a group starting treatment immediately (after satisfying the intake criteria) and which lasts for four weeks. The second half of the sample will serve as a waiting list control group, starting treatment after a waiting period of, at minimum, four weeks.

Summary
Brief summary
The aim of this project is to develop, implement and evaluate a self-sustained virtual out-door clinic for traumatized patients (http://mandarin.mytraumarecovery.com). The virtual treatment center for posttraumatic stress disorder (PTSD) applies the multimodal program “My trauma recovery” as the main technological tool. Its modules focus on social support, cognitive restructuring (“self talk”), relaxation, coping, trigger recognition, and recognition of the need for further professional help. It contains various technological advantages, such as progress charts and interactive tools. The scientific goal is to conduct a comprehensive randomized-controlled trial of internet-based treatment of PTSD for Chinese patients. Half of the sample will be randomly allocated to a group starting treatment immediately (after satisfying the intake criteria) which lasts for four weeks. The second half of the sample will serve as a wait list control group, starting treatment after a waiting period of, at minimum, four weeks. Follow-up assessments will be conducted at the end of treatment and 3 months following the completion of treatment. It is expected that the Internet-based intervention reduce significantly participants’ distress of Posttraumatic Stress Disorder.
