Abstract

Objective:

To summarize findings of previous studies on the prevalence of trauma and Posttraumatic Stress Disorder (PTSD) in Conduct Disorder (CD).

Method:

We conducted a systematic review and meta-analysis following the PRISMA guidelines. EBSCOhost, PubMed, CDSR and ARIF databases were searched in October 2016, employing relevant keywords.

Results:

19 studies met inclusion criteria. Meta-analysis resulted in a lifetime PTSD prevalence of 11% (95% CI: 7–17%) in children and adolescents with CD, 14% (95% CI: 12–15%) in adults with pre-existing CD and 32% (95% CI: 25–40%) in juvenile offenders with CD. Higher lifetime PTSD prevalence was observed in individuals with than without CD, and in females compared to males with CD.

Conclusions:

Studies focusing on the association of trauma, PTSD and CD are still relatively rare. Possible comorbidity models are discussed considering psychological and biological risk factors in a comprehensive model. The high rate of PTSD in CD may be due to shared risk factors; furthermore, CD might increase the risk for comorbid PTSD due to CD inherent risk taking behavior. To study pathways of risk, especially longitudinal studies are necessary.
