Abstract:
The reliability and validity of the SCL-90-R Obsessive Compulsive Scale were examined using a multi-trait multi-method approach in a sample of 54 outpatients with obsessive-compulsive disorder (OCD). The OC scale proved to be internally consistent. Evidence for convergent validity was mixed, and the results suggest poor divergent and criterion-related validities. The scale demonstrated sensitivity to changes with behavioral treatment. Overall, the SCL-90-R proved to be a poor measure of OCD symptoms.
