This pilot study examined a peer-facilitated trauma-focused intervention among 624 incarcerated men (Exploring Trauma). Pre- and postintervention data were collected on trauma-related mental health symptoms, aggression, and anger. The results demonstrated statistically significant improvement in trauma-related symptoms relative to pretreatment functioning and demonstrated support for the feasibility of peer-facilitation. Effect sizes were small to moderate, with the largest impact on current traumatic distress, depression, and anxiety (Cohen’s d = .54, .48, .46, respectively). The mixed-effects regression results showed the impact of adverse childhood experiences (ACEs) on outcomes was strong and cumulative (i.e., greater exposure to ACEs increased the likelihood of participant program gain on mental health and aggression symptoms, ranging from .15 to .77). The findings showed that trauma can be safely addressed in corrections and provide promising support for peer-facilitation with training and oversight. Rigorous studies are needed on the impact of trauma-informed services and models of program delivery.

这项试点研究检查了 624 名被监禁男子（探索创伤）中的同伴促进的以创伤为重点的干预措施。收集了有关创伤相关的心理健康症状、攻击性和愤怒的干预前后数据。结果表明，相对于治疗前的功能，创伤相关症状在统计学上有显着改善，并证明了对同伴促进的可行性的支持。效应量从小到中等，对当前的创伤性痛苦、抑郁和焦虑影响最大（Cohen's d= .54、.48、.46）。混合效应回归结果显示，不良童年经历 (ACE) 对结果的影响是强烈且累积的（即，更多地接触 ACE 会增加参与者计划获得心理健康和攻击症状的可能性，范围从 0.15 到 0.77 ）。研究结果表明，创伤可以在矫正中安全地解决，并通过培训和监督为同伴促进提供有希望的支持。需要对创伤知情服务和项目实施模式的影响进行严格的研究。
