Predictors associated with improved cognitive-behavioral therapy outcome in pediatric obsessive-compulsive disorder

Area of Science:

• Child and Adolescent Psychiatry
• Behavioral Therapy Research
• Mental Health Studies

Background:

• Obsessive-Compulsive Disorder (OCD) significantly impacts children and adolescents.
• Exposure-based cognitive-behavioral therapy (CBT) is a primary treatment for pediatric OCD.
• Identifying predictors of treatment response is crucial for optimizing care.

Purpose of the Study:

• To identify predictors of treatment response in pediatric OCD patients.
• To analyze outcomes after 14 weekly sessions of exposure-based CBT.
• To evaluate factors influencing treatment success in a large cohort.

Main Methods:

• The Nordic Long-term Obsessive compulsive disorder (OCD) Treatment Study (NordLOTS) included 269 participants (7-17 years).
• 20 potential predictors were assessed using univariate and multivariate analyses.
• Treatment response was measured by the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS), with ≤15 as the primary outcome.

Main Results:

• Univariate analyses revealed older age, higher OCD severity, functional impairment, and comorbid anxiety/depression predicted poorer outcomes.
• In multivariate analysis, only age remained a significant predictor of better treatment outcome.
• Comorbid symptoms significantly impacted treatment outcomes in pediatric OCD.

Conclusions:

• Age is a key predictor of treatment success in pediatric OCD patients undergoing CBT.
• While univariate analysis identified several predictors of poorer outcomes, only age was significant in the multivariate model.
• Future research should focus on optimizing interventions for pediatric OCD, particularly addressing comorbidity.
