Yale Brown Obsessive-Compulsive Scale (Y-BOCS)

If your patient can answer immediately, it can take anywhere between 1 to 5 minutes at the very least.

Just add up the scores per item based on their answers.

Note down the score range and designation they fall on, then conduct more assessments, check the patient’s medical history, and cross-check all the information you have about your patient with the criteria for OCD in the Diagnostic and Statistical Manual of Mental Disorders. If they fit the bill, then you can make an official diagnosis, but remember that the Y-BOCS on its own is not enough and should not be the sole factor in diagnosing a patient with OCD.
