Y-BOCS: what it measures, how scoring works & free alternatives
What it measures
The Y-BOCS is a clinician-rated, 10-item scale that grades the severity of obsessions and compulsions over the past week across time spent, interference, distress, resistance and degree of control, independent of the content of symptoms.
How scoring works
Each item is rated 0 to 4. The obsession items (1 to 5) and compulsion items (6 to 10) form subtotals that sum to 0 to 40, with bands of 0 to 7 (subclinical), 8 to 15 (mild), 16 to 23 (moderate), 24 to 31 (severe) and 32 to 40 (extreme).
Why there's no free Y-BOCS here
The Y-BOCS is owned by OCD Scales, LLC. A licensing agreement is explicitly required for commercial use, EMR incorporation, inclusion in an app, digitalisation and translation, so we cannot host it. The OCI-R is a free, self-report alternative you can score here.
