Online Radical Acceptance Intervention for Social Anxiety Disorder

The goal of this clinical trial is to learn if a self-guided online Radical Acceptance program helps reduce symptoms of Social Anxiety Disorder. The study will also compare this program to an online relaxation skills program.

The main questions are:

* Does the Radical Acceptance program lower symptoms of Social Anxiety Disorder? * Is the Radical Acceptance program more helpful than relaxation skills?

Adults with Social Anxiety Disorder will be randomly assigned to one of two online programs. They will complete a baseline learning session and six short home practice sessions over two weeks. Participants will answer surveys about their symptoms and complete brief computer tasks. Researchers will measure changes in social anxiety at several points during the study and again a few weeks and a few months later.
