Modular CBT for Childhood Anxiety Disorders: Evaluating Clinical Outcomes and its Predictors

This study examined clinical outcomes of a modular individual CBT for children with anxiety disorders (AD), and predictors of outcomes, in usual clinical practice. Participants were 106 children with ADs (7-17 years), and parents. Assessments were pre-, mid-, post-test, and 10 weeks after CBT (follow-up). Predictors (measured pre-treatment) were child characteristics (gender, age, type of AD, comorbid disorders), fathers' and mothers' anxious/depressive symptoms, and parental involvement (based on parents' presence during treatment sessions and the use of a parent module in treatment). At follow-up, 59% (intent-to-treat analyses) to 70% (completer analysis) of the children were free from their primary anxiety disorder. A significant decrease in anxiety symptoms was found. Higher parental involvement was related to lower child anxiety at follow-up, but only for children with comorbid disorders. Findings suggest that it is beneficial to treat anxiety with modular CBT. Future steps involve comparisons of modularized CBT with control conditions.
