Given the high degree of diagnostic overlap and limited empirical literature surrounding the comorbidity between posttraumatic stress disorder (PTSD) and obsessive-compulsive disorder (OCD), appropriately conceptualizing the relationship between the comorbid symptoms and their impact on the treatment process can be challenging. This is especially true when the symptoms of the two disorders become functionally connected, with each symptom set maintaining the other. This article details the case of a veteran with comorbid PTSD and OCD who sought intensive trauma-focused treatment within the U.S. Veterans Health Administration. The dynamic relationship between his PTSD and OCD symptoms is described, along with its impact on trauma-focused treatment and the ability to maintain treatment gains. A novel attempt to integrate empirically based treatment strategies for OCD into intensive PTSD treatment, targeting both sets of symptoms simultaneously, is presented, along with implications for conceptualization and treatment of this comorbidity.
