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

TL;DR

A randomized controlled trial in 95 Chinese university students compared peer-delivered Eye Movement Desensitization plus Imagery Rescripting (EMD + IR) versus standalone IR and care-as-usual for moderate post-traumatic stress. Both interventions improved outcomes, but EMD + IR demonstrated superior stability in maintaining resilience gains at one-month follow-up.

Key findings

• EMD + IR group maintained resilience gains at one-month follow-up, while standalone IR group showed significant decline
• Resilience improvements were mediated by multi-dimensional restructuring of traumatic memories: reduced vividness, arousal, and negative beliefs
• Peer-delivered model was feasible and culturally acceptable, with participants reporting EMD provided sensory-affective buffering and egalitarian peer identity reduced hierarchical stigma
• Non-significant Group × Time interactions for depression, anxiety, and self-efficacy, suggesting effects may emerge at longer follow-up or require larger sample sizes

Why this matters at the bedside

Demonstrates task-sharing as a scalable implementation strategy for evidence-based trauma interventions in resource-limited, high-stigma settings; peer-delivered EMD + IR shows promise for sustainable post-traumatic growth in non-Western populations.
