Acceptance Commitment Therapy (ACT) is known to help people recover from depression by improving psychological flexibility through acceptance, defusion, self-as-context, present moment, committed action, and helping them live a values-based life. This study is a randomized controlled trial to determine if web-based ACT leads to changes in the psychological flexibility and cognitive fusion. Also, through the functional MRI study, possible treatment mechanisms by which the web-based ACT exerts will be identified.
