Peer-delivered combined EMD and imagery rescripting for traumatized Chinese university students: a RCT.

Area of Science:

• Psychology
• Global Mental Health
• Intervention Science

Background:

• Evidence-based trauma interventions are often limited to Western populations.
• Implementing these in non-Western settings faces barriers like mental health professional shortages and cultural stigma.
• Task-sharing models are essential for global mental health equity.

Purpose of the Study:

• To evaluate the efficacy of a peer-delivered integrated intervention (EMD + IR) for traumatized Chinese university students.
• To explore the underlying mechanisms of this culturally adapted intervention.
• To assess the feasibility and cultural congruence of task-sharing trauma interventions.

Main Methods:

• A randomized controlled trial (RCT) with 95 students with moderate post-traumatic stress.
• Comparison of peer-delivered EMD + IR, standalone IR, and care-as-usual (CAU).
• Mixed-methods design including quantitative outcome assessments and qualitative interviews.

Main Results:

• Both interventions improved outcomes over time, but EMD + IR showed superior resilience maintenance at follow-up.
• Resilience gains were mediated by restructuring traumatic memories (reduced vividness, arousal, negative beliefs).
• Qualitative data highlighted the 'sensory-affective buffer' of EMD and the destigmatizing effect of peer delivery.

Conclusions:

• Task-sharing EMD + IR via trained peers is a feasible and culturally congruent trauma intervention strategy.
• This phased, peer-led model offers a safe, destigmatizing pathway for trauma symptom relief.
• The approach supports sustainable post-traumatic growth in non-Western higher education settings.
