Assessing Obsessive-Compulsive Disorder (OCD): A Review of Diagnostic Interviews and Clinician-Rated Instruments - Abstract
Obsessive-compulsive disorder (OCD) affects approximately 2- 2.5% of the adult population and 21%-25% of individuals from the general population subclinically. Assessing OCD is complicated by its own heterogeneity and its diagnostic differentiation from other disorders, as diagnostic comorbidity with other mental disorders is high. Improving assessment and diagnosis of OCD thus remains an important area of focus for research and clinical practice. A crucial component in this is having an overview of OCD measures that compliments the review of self-report measures of OCD. This paper provides a critical and comprehensive overview of two diagnostic interviews and five clinician-rated OCD assessment measures commonly used with adults, including a family-report measure and behavioural assessment. The measures are evaluated based on their psychometric properties and practical utility, providing a resource for clinicians and researchers to facilitate their selection of OCD measure to serve their specific clinical or research aims.
