The Yale–Brown Obsessive Compulsive Scale, sometimes referred to as Y-BOCS, is a test to rate the severity of obsessive–compulsive disorder (OCD) symptoms. The scale, which was designed by Wayne K. Goodman and his colleagues, is used extensively in research and clinical practice to both determine severity of OCD and to monitor improvement during treatment.〔Goodman W.K, Price L.H, Rasmussen S.A, et al. The Yale–Brown Obsessive–Compulsive Scale. I. Development, use, and reliability. Arch Gen Psychiatry 1989;46:1006–1011. PMID 2684084〕 This scale, which measures obsessions separately from compulsions, specifically measures the severity of symptoms of obsessive–compulsive disorder without being biased towards the type of content of obsessions or compulsions present.〔Rosario-Campos MC, Miguel EC, et.al The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS): an instrument for assessing obsessive-compulsive symptom dimensions. Mol Psychiatry. 2006 May;11(5):495-504 PMID 16432526〕〔Garnaat SL, Norton PJ. Factor structure and measurement invariance of the Yale-Brown Obsessive Compulsive Scale across four racial/ethnic groups. J Anxiety Disord. 2010 May 24. PMID 20541907〕 == Scoring == The scale is a clinician-rated, 10-item scale, each item rated from 0 (no symptoms) to 4 (extreme symptoms), yielding a total possible score range from 0 to 40. The scale includes questions about the amount of time the patient spends on obsessions, how much impairment or distress they experience, and how much resistance and control they have over these thoughts. The same types of questions are asked about compulsions (e.g., time spent, interference, etc.) as well. The results can be interpreted based on the total score: * 0–7 is sub-clinical; * 8–15 is mild; * 16–23 is moderate; * 24–31 is severe; * 32–40 is extreme. Patients scoring in the mild range or higher are likely experiencing a significant negative impact on their quality of life and should consider professional help in alleviating obsessive–compulsive symptoms. A self-rated version of the Yale-Brown Obsessive-Compulsive Scale has been developed. The self-report and clinician-administered versions of the Y-BOCS are correlated to each other.〔Federici A, Summerfeldt LJ, et. al Consistency between self-report and clinician-administered versions of the Yale-Brown Obsessive-Compulsive Scale.J Anxiety Disord. 2010 May 24.
