At the time of this study, patients with combined OCD and post-traumatic stress disorder (PTSD) were often not responsive to behavioral therapies and pharmacological treatments. More research was needed regarding the prevalence of trauma and PTSD in OCD patients who sought treatment.
This study by Drs. Gershuny, Baer, Foa, and their team analyzed the traumatic experiences of 104 participants with treatment-resistant OCD to determine the prevalence of trauma and PTSD. 82% of participants had a history of trauma and almost half met diagnostic criteria for PTSD, suggesting a strong link between traumatic experiences and OCD that does not respond to treatments. Events such as childhood sexual abuse, witnessing violence in childhood, and experiencing a natural disaster were strong predictors of PTSD severity; comorbid major depressive disorder and borderline personality disorder were also strongly linked to meeting PTSD criteria.
