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.
