Study of a Group-Based Transdiagnostic CBT Program for Treating Anxiety Disorders Including Generalized Anxiety, Panic, and Social Anxiety Disorders

What this Trial Is About

Researchers are evaluating a transdiagnostic cognitive behavioral therapy CBT protocol designed to address common features such as distress intolerance, intolerance of uncertainty, and worry that underlie various anxiety disorders. The study aims to develop this unified protocol UP in Turkish, apply it as group therapy, and assess its effect on these common features as well as symptom severity across different anxiety disorders. The research also explores whether changes in these common features can predict symptom severity levels. The study includes two groups an intervention group receiving the UP based on the CBT model and a supportive therapy group serving as a control. The UP consists of eight weekly group sessions of one and a half hours each, covering assessment, psychoeducation, emotions, thoughts, behaviors, and review, followed by a one-month follow-up session. The supportive therapy group also meets for eight weeks plus a follow-up, providing a non-directive, empathic environment without CBT interventions. Participants will complete several assessments before the first session, after the eighth session, and at the one-month follow-up. These include measures of anxiety, distress tolerance, intolerance of uncertainty, worry, metacognition, and depression. The study uses random assignment to groups and single masking. The total participation covers the 8-week intervention plus the follow-up, with evaluations focused on the effectiveness of the transdiagnostic protocol and changes in common emotional disorder features.
