Yale-Brown Obsessive Compulsive Scale (Y-BOCS)

The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is a questionnaire used by mental health professionals to measure the severity of obsessive-compulsive disorder (OCD). It assesses the frequency, distress, and impact of obsessive thoughts and compulsive behaviors over the past week. The scale helps clinicians understand how much OCD affects a person’s daily life and guides treatment planning. It is a standardized tool that provides a numerical score, with higher scores indicating more severe symptoms, facilitating objective tracking of changes over time.
