Efficacy of exposure in group settings for youth with posttraumatic stress symptoms

Kurzfassung/Abstract

Background
Exposure to traumatic experiences is a fundamental part of evidence-based trauma-focused cognitive behavioral treatment (CBT) but in group settings it is discussed controversially among researchers and practitioners. This study aims to examine the individual participants’ stress level during group sessions with exposure and disclosure of traumatic events.

Method
N = 47 traumatized youth ( M age = 17.00, 94% male) participated in a group intervention comprising six 90-min group sessions (exposure in sessions 2–5). It is based on trauma-focused CBT principles. The individual stress level was assessed by the participants and group facilitators at the beginning, during, and at the end of every session.

Results
During the sessions including exposure, the stress level of the participants was higher than during sessions without exposure ( Z = − 3.79; p ≤ .001). During the exposure sessions, the participants showed significant changes in stress level ( d = 0.34–0.87) following an inverse U-shaped trend.

Conclusion
The results show that exposure is feasible within the scope of a trauma-focused group intervention for youth. The further dissemination of trauma-focused group treatments is an important component in the mental health care of children and youth who are traumatized.
