The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is a widely used clinical instrument for assessing the severity of obsessive-compulsive disorder. It breaks symptoms into two domains: obsessions and compulsions. Each domain consists of five questions rated from zero to four. Time consumed, interference in daily life, emotional distress, resistance, and perceived control all factor into the final score. Unlike simpler screening tools, the Y-BOCS captures nuances that can guide treatment decisions and track response over time. Higher scores indicate more severe OCD symptoms and may signal the need for more intensive therapy or medication. Use this calculator to tally your scores quickly and interpret the overall severity.

Though the Y-BOCS is structured, obsessive-compulsive disorder manifests in many forms. Some people experience intrusive thoughts that cause intense anxiety, compelling them to perform ritualistic behaviors for relief. Others struggle with mental compulsions such as repeating phrases or counting to prevent a feared event. The scale’s questions account for variations in symptom presentation. For instance, someone might spend hours checking door locks or washing hands, while another person primarily experiences intrusive thoughts of harming loved ones. By quantifying time, interference, and distress separately, the Y-BOCS reveals how OCD affects day-to-day functioning in diverse scenarios.

Healthcare professionals often administer the Y-BOCS during initial evaluations and again after a course of treatment. A change in score reflects improvements or worsening of symptoms. This makes the tool valuable for monitoring the effectiveness of cognitive-behavioral therapy, medication adjustments, or exposure and response prevention techniques. In clinical studies, a reduction of about 25% in the Y-BOCS score is considered a meaningful response to treatment. If your score remains high despite efforts to manage your symptoms, discuss additional strategies or referrals with your healthcare provider.

Self-assessment can be illuminating, but it is not a substitute for professional care. OCD often coexists with other conditions like anxiety or depression, and a mental health professional can help tease apart these overlapping issues. They can also provide a tailored treatment plan that addresses your specific obsessions and compulsions. If your Y-BOCS score falls in the moderate or severe range, consider scheduling an evaluation to explore therapy options. Remember that symptoms can fluctuate over time, especially during stressful events or life transitions. Tracking your score periodically helps you and your provider adjust interventions accordingly.

While the Y-BOCS was developed in an academic setting, it has proven useful in everyday clinical practice and research trials. Scores from 0 to 7 are generally considered subclinical, meaning symptoms cause little to no impairment. Scores from 8 to 15 indicate mild symptoms, 16 to 23 suggest moderate OCD, 24 to 31 mark severe symptoms, and 32 to 40 reflect extreme impairment. Knowing where you fall on this spectrum can validate your experiences and provide a benchmark for progress. Use this tool alongside other self-care strategies like mindfulness or journaling to maintain perspective on your mental health journey.

Obsessive-compulsive disorder can be isolating, but you are not alone. Online support groups and counseling services offer community and guidance. Sharing your challenges with others who understand can reduce feelings of shame or anxiety. The Y-BOCS score is simply one data point in your broader story. As you explore treatment options, remember to celebrate small victories—whether it’s reducing the number of rituals you perform or spending less time stuck in obsessive thoughts. Over time, these incremental improvements add up and help you reclaim more of your day.

If you find yourself consumed by obsessions or compulsions, reach out for professional help. Effective therapies exist, and many people achieve significant relief with the right approach. Use this calculator as an entry point for discussions with your healthcare provider. Together you can develop a comprehensive plan that addresses the root of your symptoms and supports your overall well-being.
