Current severity benchmarks of OCD severity on the Y-BOCS are sublinical OCD (0-13 points), mild OCD (14-21 points), moderate OCD (22-29 points) and severe OCD (30-40) [@cervin2022].
Key takeaways
- Data from Sweden, Brazil, South Africa, US, and India (external data). Total n except India = 3784
- 80/20 split of n = 3784, and external validation on India data (n = 1356)
- Moderate accuracy for severity benchmarks on holdout (57%) and external (55%) datasets
In summary, we provide the field with empirically derived Y-BOCS severity benchmarks across the lifespan which will be useful in research and clinical settings (subclinical OCD: 0-13 points; mild OCD: 14-21 points; moderate OCD: 22-29 points; severe OCD: 30-40 points).
