The Mediating Role of Emotion Dysregulation in the Association Between Trait Mindfulness and PTSD Symptoms among Trauma-Exposed Adults

Objectives Growing evidence of the effectiveness of mindfulness-based interventions for posttraumatic stress disorder (PTSD) warrants greater understanding of factors relevant to the relation between trait mindfulness and PTSD, such as emotion dysregulation (ED). The goal of this study was to examine associations between trait mindfulness, ED, and PTSD symptoms across two samples of trauma-exposed adults. Methods Participants for Sample 1 ( n = 39, 90% women, 100% Black) and Sample 2 ( n = 60, 100% women, 87% Black) were recruited from an urban hospital in the South. Trait mindfulness, ED, and PTSD were assessed. Results Across both samples, mindfulness and ED were significantly associated with overall PTSD severity ( r = − .49 and r = − .42, ps = .001; r = .53 and r = .51, ps
