Thought disorder in patients with obsessive-compulsive disorder

We examined the presence of disordered thinking/perception in patients with obsessive-compulsive disorder (OCD). Recently, an obsession model has been proposed, which classifies obsessions into two different subtypes: autogenous obsessions and reactive obsessions (Lee & Kwon, 2003). Based on this model, we hypothesized that OCD patients primarily displaying autogenous obsessions as opposed to reactive obsessions would display more severely disordered thinking/perception. We compared 15 OCD patients primarily displaying autogenous obsessions (AOs), 14 OCD patients primarily displaying reactive obsessions (ROs), 32 patients with schizophrenia (SPBs), and 28 patients with other anxiety disorders (OADs) with respect to thought disorders as assessed by the Comprehensive System of the Rorschach Inkblot Test. Results indicated that both AOs and SPRs displayed more severe thought disorders compared to ROs or OADs. Theoretical and clinical implications are discussed. (c) 2004 Wiley Periodicals, Inc.
