This study aims to examine the effectiveness of group Guided Written Exposure Therapy for Complex Post-Traumatic Stress Disorder (GWE-C) among Chinese adolescents through a randomized controlled trial. A total of 120 participants will be recruited, with 60 randomized to the GWE-C group and 60 randomized to the supportive therapy (ST) group. The GWE-C intervention will consist of 7 to 10 group sessions. The primary outcome, assessed by the International Trauma Questionnaire (ITQ), will be measured at baseline, post-treatment, 1-month follow-up, and 3-month follow-up.

| Group Guided Written Exposure Therapy for CPTSD (GWE-C) | Behavioral | Group Guided Written Exposure Therapy for CPTSD (GWE-C) is a manualized, exposure-based therapeutic program consisting of 7 to 10 sequential sessions. The intervention follows a structured sequence of trauma processing that addresses trauma details, associated emotions, cognitions, and impacts. Writing tasks incorporate imagery dialogues, self-compassion exercises, and resource identification to help participants alleviate C-PTSD symptoms. The interval between two consecutive sessions ranges from 0 to 2 days, with participants expected to complete all sessions within 1 to 2 weeks. The first and last sessions are scheduled to last 1.5 hours each, while the intermediate sessions are 60 minutes in duration. Each group will consist of 6 to 10 participants and will be facilitated by one counselor and one assistant. |

| Supportive Group | Behavioral | Supportive group, the comparator intervention, is a non-trauma-focused treatment based on the Rogerian psychotherapy model and has been used as an active comparator in previous trials of trauma-focused therapies. The program comprises seven sessions: the first two employ group activities such as card games and interactive drawing to build a sense of belonging; sessions three to six focus on stress management and emotion regulation skills through methods including expressive drawing, relaxation training, and resource identification; the final session emphasizes reflection and sharing. Throughout, counsellors provide supportive guidance to encourage emotional expression, mutual listening, and peer support, while discussions deliberately exclude participants' individual traumatic experiences. |
