NCT06931093

Brief Summary

This study aims to examine the effectiveness of group-delivered 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.

Outcome Measures

Primary Outcomes (2)

  • CPTSD Symptom Severity (self-report)

    International Trauma Questionnaire-Child and Adolescent Version (ITQ-CA; Cloitre et al.,2018 ) is a self-report measure that assesses ICD-11 PTSD and CPTSD. The measure includes 6 core items of PTSD symptom clusters (ie. re-experiencing, avoidance, sense of threat), 6 core items of Disturbances in Self-Organization (DSO) clusters (ie affective dysregulation, negative self-concept, disturbed relationships). Each item is rated from 0(not at all) to 4(extremely). The Chinese version has been demonstrated good psychometric properties (Ho et al., 2022).

  • CPTSD Symptom Severity(interview)

    The Child CPTSD Symptom Interview (CCSI) is a 12-item semi-structured interview developed by adapting items from the Child PTSD Symptom Scale-Interview Version for DSM-5 (CPSS-5-I) and the International Trauma Interview (ITI).The PTSD section of the CCSI includes two items for each of the three PTSD symptom clusters, following the structure of the CPSS-5-I: re-experiencing (Re), characterized by flashbacks or nightmares; avoidance (Av), referring to avoidance of internal or external reminders of the traumatic event; and a sense of current threat (Th), expressed through hypervigilance or exaggerated startle reactions.The second part assesses Disturbances in Self-Organization (DSO) symptoms, based on the structure of the ITI (Roberts et al., 2019), with two items per DSO symptom cluster.

Interventions

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.

GWE-C

Supportive counselling, 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.
