Single (N = 472, 51.7%), married or living in stable cohabitation (N = 375, 41.1%) and divorced or separated (N = 66, 7.2%) patients with obsessive-compulsive disorder (OCD) were compared in terms of their sociodemographic features, OCD phenotypes, and comorbidity profile. Using single status as a reference group, a multinominal regression analysis found increased age, lower severity of hoarding, increased rates of panic disorder without agoraphobia, and lower rates of dysthymic disorder to be associated with married or stable cohabitation status. Concomitantly, increased age, higher severity of symmetry symptoms, and increased rates of skin picking disorder were found to be associated with divorced status. These findings suggest that there is a relationship between marital status and different OCD phenotypes.
