Defining clinical severity in pediatric obsessive-compulsive disorder

Area of Science:

• Child and Adolescent Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• The Children's Yale Brown Obsessive Compulsive Scale (CYBOCS) is widely used for assessing obsessive-compulsive disorder (OCD) symptom severity in youth.
• A lack of normative data for the CYBOCS hinders the accurate interpretation of individual patient scores.

Purpose of the Study:

• To present psychometric data for CYBOCS severity scores in a large sample of youth with OCD.
• To establish normative comparisons for obsessive, compulsive, and total CYBOCS scores across age and sex.
• To provide empirically based guidelines for interpreting CYBOCS scores in clinical and research settings.

Main Methods:

• Collected CYBOCS severity scores from 815 treatment-seeking youth diagnosed with OCD.
• Analyzed data to identify age and sex differences in symptom severity.
• Correlated CYBOCS scores with the Clinician Global Impression-Severity (CGI-S) scale.

Main Results:

• No significant age or sex differences were found in CYBOCS severity scores.
• CYBOCS obsessive-compulsive symptom severity scores showed a moderate correlation with global OCD severity (r = .58).
• The study provides the first empirical guidelines for interpreting CYBOCS severity scores.

Conclusions:

• The CYBOCS is a reliable measure for assessing OCD symptom severity in youth.
• Normative data support the consistent use of CYBOCS across different demographics.
• These findings will aid clinicians and researchers in interpreting CYBOCS scores and comparing severity across studies.
