What predicts improvement and compliance during the behavioral treatment of obsessive compulsive disorder?

The aim of the study was to identify factors associated with treatment compliance and clinical improvement when obsessive compulsive disorder is treated with graded exposure and response prevention. The sample consisted of all patients with a diagnosis of obsessive compulsive disorder admitted over a 3-year period to a unit specialising in behavioral treatment. All subjects were diagnosed using reliable diagnostic criteria and all were followed-up for 12 months. A range of social and clinical variables was examined using stepwise regression analysis. Treatment compliance was associated with being employed during treatment and living with one's family. Clinical improvement was associated with never having been treated previously, being employed during treatment, having a fear of contamination, having overt ritualistic behaviour, the absence of depression and living with one's family.
