Evaluation of a Peer-Facilitated Trauma Intervention for Incarcerated Men

Abstract

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.
