This study compares two school-based cognitive behavioral therapy (CBT) programs for adolescent anxiety. A less intensive CBT program may be as effective as a more intensive one, improving access to care.
Area of Science:
- Child and Adolescent Psychiatry
- Clinical Psychology
- Public Health Interventions
Background:
- Anxiety disorders significantly impact adolescents, with potential long-term consequences.
- Many adolescents do not access effective treatments like cognitive behavioral therapy (CBT).
- School-based, low-intensity CBT interventions can enhance access to evidence-based mental health services.
Purpose of the Study:
- To evaluate the efficacy of two school-based CBT programs for youth anxiety with varying intensities.
- To determine if a less intensive CBT intervention is non-inferior to a more intensive one.
- To examine the effects of early, school-administered interventions on adolescent anxiety.
Main Methods:
- Randomized controlled trial across 18 schools involving 323 adolescents (12-16 years).
- Comparison of two group-based CBT interventions against a waitlist control group.
- Primary outcomes: anxiety symptoms and functional impairments; secondary outcomes: depressive symptoms, quality of life, psychosocial functioning.
Main Results:
- The study is designed to determine non-inferiority if the anxiety symptom difference is ≤1.4 and interference scale difference is ≤0.8.
- Mixed-effect models with intention-to-treat analysis will be used.
- Results will indicate the comparative effectiveness of different CBT intensities in a school setting.
Conclusions:
- A brief, less intensive CBT intervention, if effective, could facilitate large-scale implementation in school health services.
- School-based interventions offer a promising avenue for addressing adolescent anxiety.
- Findings will inform the optimal delivery model for CBT in schools.
