OCD Assessment

About This Assessment

This questionnaire includes two brief scales your clinician uses to better understand your experience. There are no right or wrong answers — your honest responses help us understand what you've been noticing and feeling.

The first part asks about different types of worries or concerns you may have had over the past week. The second part asks about how you relate to unwanted thoughts that may come to mind.

The whole thing takes about 10–15 minutes.

This is not a diagnostic tool. Results will be reviewed with your clinician and are one piece of the clinical picture. If you are in crisis, please contact the 988 Suicide and Crisis Lifeline by calling or texting 988.

A note about these results

These scores are a starting point for a clinical conversation, not a diagnosis. Many factors shape how you experience intrusive thoughts, and your clinician will put these numbers in context alongside everything else they know about you.

If anything in this questionnaire brought up difficult feelings, you are not alone — and you don't have to figure this out by yourself. Please bring this to your next session.
