Purpose of Review

This review focused on literature from the past five years that examined the role of emotion dysregulation in co-occurring symptoms of posttraumatic stress disorder (PTSD) and substance use disorder (SUD) among adults.

Recent Findings

Evidence from recent studies indicates that emotion dysregulation operates directly by exacerbating symptoms of PTSD and SUD and functions as both a moderator and mediator in the PTSD-SUD relation. Greater emotion dysregulation tends to strengthen the association between PTSD and SUD symptoms. Moreover, evidence supports emotion dysregulation as a key target in trauma- and SUD-focused treatments, with reductions in emotion dysregulation contributing to better clinical outcomes across diverse treatment settings.

Summary

Emotion dysregulation is a critical factor that underlies the co-occurrence of PTSD and SUD. Understanding the nuanced role of emotion dysregulation in co-occurring PTSD-SUD offers critical insights for alleviating PTSD symptoms and SUD behaviors, especially intrusive memories and using substances as avoidance.
