OCD test: OCI-R vs Y-BOCS — which instrument for which task
Each month 7,800+ people search for "OCD test" and variants. OCD has two distinct validated instruments: OCI-R (Foa et al. 2002, 18-item self-report, 5 minutes, cut-off ≥21) and Y-BOCS (Goodman et al. 1989, 10-item clinician-rated, 30–45 minutes, gold-standard severity). These are <strong>not alternatives — they cover different tasks</strong>: one for screening, the other for diagnostic clarification and treatment monitoring. And a core fact: OCD rarely comes alone (Pinto et al. 2006, N=293, 91% lifetime ≥1 comorbid disorder).
