Abstract

The original Maudsley Obsessional Compulsive Inventory (MOCI) has been widely used and is considered to be one of the best available self-report instruments for measuring observable obsessive-compulsive problems such as washing and checking. However, it has several limitations and requires updating. Our revision of the MOCI, the Vancouver Obsessional Compulsive Inventory (VOCI), was designed to provide assessment of a range of obsessions, compulsions, avoidance behaviour, and personality characteristics of known or theoretical importance in obsessive-compulsive disorder (OCD). The development of the VOCI is described, and we provide evidence of its reliability and validity. Our findings in samples of people with OCD, people with other anxiety disorders or depression, community adults, and undergraduate students suggest that the VOCI is a promising new measure. We anticipate that, like its predecessor, the VOCI will have widespread use in both research and clinical settings.
