Rating Scales Information for OCD Professionals

Our program is pleased to share the following information for professionals involved in treating and researching OCD and related disorders.

Assessing the Severity of OCD

One of the most widely used instruments for assessing OCD includes a symptom checklist that includes about 75 examples of obsessions and compulsions. This instrument, called the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), is ordinarily used by trained professionals to evaluate OCD. The scale -developed by Wayne Goodman, MD, and Steven Rasmussen, MD, and Lawrence Price, MD - contains two parts: 1) the Symptom Checklist and 2) the 10-item severity measure. The psychometric properties of the Y-BOCS have been extensively studied (Goodman et al 1989; Goodman et al 1989).

More recently, the original developers along with Eric Storch, PhD, of the University of South Florida (Storch et al, 2010), created a new version of the Y-BOCS (referred to as the Y-BOCS II).

Please send us details of your specific request including the following information: Trial sponsor, indication, number of subjects, number of assessments per subject and anticipated study start date.

If you are interested in utilizing the scales for clinical purposes—including clinical practice or clinical research—you are permitted to use the scale provided you agree to the following terms. These terms ONLY apply to individuals and institutions NOT performing industry-sponsored work.
