Trait mindfulness and PTSD symptom clusters: Considering the influence emotion dysregulation

Mindfulness is considered a multifaceted construct consisting of non-judging, non-reactivity, describing, observing, and acting with awareness. Mindfulness has received increased attention for its use in the treatment of psychological disorders, including posttraumatic stress disorder (PTSD), though little is known about how mindfulness facets relate to PTSD symptom clusters. The current study performed a path analysis to examine these relationships while controlling for emotion dysregulation in a sample of 298 college undergraduates with endorsed trauma histories. Hypotheses about the specific proposed relationships were partially supported. Above and beyond emotion dysregulation, non-judging was negatively related to the re-experiencing and negative alternations in cognitions and mood symptom clusters and was marginally related to hyperarousal. Additionally, acting with awareness was negatively related to hyperarousal, whereas non-reactivity was unexpectedly positively associated with hyperarousal. Overall, findings suggest the mindfulness facet most relevant to PTSD may be non-judging of inner experience.
