| Field | Instrument context |
|---|---|
| Version | CY-BOCS; original clinician-rated child OCD severity form |
| Population | Children/adolescents; verify age range for selected form |
| Respondent | Clinician with child/caregiver input |
| Purpose | Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS) — administration and scoring reference. |
Administration
Establish the child’s obsessions and compulsions with child and caregiver input before rating severity. A trained clinician reconciles the information and follows the child-form anchors.
Scoring method
Child-specific obsession and compulsion ratings; clinician administration required.
Interpretation & limitations
- Report obsession and compulsion severity and their supported total; symptom-checklist endorsements are not severity points.
- Interpret the findings alongside the clinical interview, functioning, history and relevant physical assessment.
- The original CY-BOCS and CY-BOCS-II are distinct. Do not transfer adult or second-edition anchors and maxima to this form.
- Use the original instrument and manual for item wording, rating anchors, missing-data rules and any normative conversions. This reference does not establish a diagnosis or select treatment.
