Obsessions and compulsions: psychometric properties of the Padua Inventory with an American college population.

The psychometric properties of the Padua inventory, a self-report measure of obsessive-compulsive behaviors, were examined in a sample of 678 American college students. Results showed good internal consistency as well as convergent and divergent validity with the subscales of the Symptom Checklist-90 Revised and the Maudsley Obsessional-Compulsive Inventory. A principal components analysis suggested a four factor solution (i.e. 'impaired control of mental activities', 'checking', 'urges and worries of losing control of motor behaviors', and 'being contaminated'). The factor structure was very similar to that found in the original Italian study of the inventory. Suggestions are made for the use of the Padua Inventory in the study of obsessions and compulsions in nonclinical samples.
