Do you have recurring thoughts or behaviors you cannot control? The Y-BOCS assesses OCD symptom severity. 10 items, about 5-10 minutes.

Uncontrollable Thoughts and Behaviors

Ever found yourself checking the door lock three times, washing your hands until they're raw, or stuck on a thought that just won't leave? Obsessions and compulsions are more common than most people realize. Clinicians routinely use the Y-BOCS to assess OCD severity.

Developed by Goodman et al. (1989), it has 10 core items split into two subscales: obsessions and compulsions. Each item is rated on a 0-4 scale.

A note: Y-BOCS was originally designed as a clinician-administered interview. This self-report version is for screening and educational purposes only. If your symptoms are interfering with daily life, please consult a mental health professional.
