Prevalence and Treatment of Obsessive-Compulsive Disorder in Veterans and Active-Duty Service Members: A Systematic Review

The prevalence and treatment of obsessive-compulsive disorder (OCD) in veterans and active-duty military remains unclear. We systematically reviewed literature on OCD diagnosis and treatment in U.S. Veterans and active-duty military to obtain a prevalence estimate, describe treatment approaches for OCD in veterans, and evaluate use of Exposure and Response Prevention (ERP). Eight terms were used to identify studies in PubMed, PsychINFO and SCOPUS up to March 13, 2018; additional articles were identified from reference lists of 19 included studies, 16 addressing prevalence, and 3 addressing treatment. OCD prevalence is lower in studies employing electronic medical records databases than in studies using OCD assessments, suggesting underrecognition of OCD in clinical settings. Higher prevalence was seen with OCD screening tools than with diagnostic interviews. Lower OCD prevalence was seen in active-duty individuals than in veterans. Two case studies showed a decrease in OCD symptoms following ERP. Additional studies with larger samples and controlled designs examining ERP are needed.
