title: Assessment of obsessive-compulsive disorder.
abstract: Self-report assessment devices of obsessive-compulsive symptoms are widely used by behavior therapists. In the present investigation, psychometric characteristics and concurrent, discriminant, and factorial validity of the Maudsley Obsessional Compulsive Inventory (MOCI) were studied in clinical samples. Test-retest reliability was high. The internal consistency was high for the total score and moderate for the subscales, checking and cleaning. The slowness and doubting subscales appeared to be less useful. The MOCI was found to reliably discriminate between obsessional patients on one hand and normals, patients with anorexia nervosa and anxiety disorders, on the other, but failed to discriminate obsessionals from depressives. Concurrent validity and factorial validity were satisfactory. The MOCI may be used to evaluate effects of treatment, but it is less sensitive than target ratings of obsessional problems.
