What this trial studies

This study investigates the efficacy of an online Acceptance and Commitment Therapy (ACT) intervention specifically designed for adolescents suffering from Social Anxiety Disorder (SAD) and Generalized Anxiety Disorder (GAD). By utilizing a transdiagnostic approach, the research aims to address the underlying psychological inflexibility that contributes to these anxiety disorders. The study employs a Randomized Controlled Trial (RCT) design with three groups to evaluate the effectiveness of the intervention and to explore the mechanisms of change during the therapy. This research seeks to fill the gap in evidence regarding ACT's applicability and effectiveness for adolescents, a demographic where anxiety disorders are prevalent.

Who should consider this trial

Good fit: Ideal candidates for this study are adolescents diagnosed with Social Anxiety Disorder or Generalized Anxiety Disorder.

Not a fit: Patients with cognitive impairments, psychotic symptoms, or those undergoing other psychiatric treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could provide adolescents with effective tools to manage anxiety and improve their psychological flexibility.

How similar studies have performed: While transdiagnostic approaches like ACT have shown promise in adult populations, this specific application to adolescents is relatively novel and has not been extensively tested.
