There is a paucity of instruments for the assessment of obsessive-compulsive symptoms in children/adolescents. The goal of this study was to assess the psychometric properties and factor structure of the Obsessive Compulsive Inventory-Revised (OCI-R) in a non-clinical sample of 269 late adolescents (M= 17.04 years old; SD= 0.74). A confirmatory factor analysis replicated the original six-factor structure of the OCI-R (Washing, Obsessing, Hoarding, Ordering, Checking and Neutralizing), but the fit indices were generally slightly lower than expected. The OCI-R total and its original subscales showed moderate internal consistency. In general, no significant gender or age differences were found. The OCI-R seems appropriate for its use in adolescent samples. Whether it will also be suitable for even younger people remains to be examined.
