A review of the long‐term impact of child maltreatment on posttraumatic stress disorder and its comorbidities: An emotion dysregulation perspective.

This review examines posttraumatic stress disorder (PTSD) related to child maltreatment in adults, PTSD comorbidities, and complex PTSD, with a focus on emotion dysregulation. Adults maltreated as children report high rates of PTSD. Although all forms of child maltreatment are associated with increased PTSD risk, effects are stronger for child sexual and emotional abuse, abuse in the context of other adverse childhood experiences, and cumulative abuse. PTSD comorbidities that involve emotion dysregulation are examined, including substance use disorders, eating disorders, and borderline personality disorder. Emotion dysregulation appears to be a coalescent factor in the nexus of child maltreatment, PTSD, and other comorbidities. Treatment recommendations are made for adults with child maltreatment–related PTSD and comorbidities.
