The Effectiveness of Group Guided Written Exposure Therapy for CPTSD Symptoms Among Adolescents

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.

Treatment and study plan

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 counselling

Behavioral

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.

Primary outcomes

  1. CPTSD Symptom Severity (self-report)

    Time frame: baseline, post treatment(2 weeks), 6 weeks, 14 weeks

    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).

  2. CPTSD Symptom Severity(interview)

    Time frame: baseline, post treatment(2 weeks), 6 weeks, 14weeks

    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.
