Acceptance and Commitment Therapy (ACT) is a mindfulness-based form of behavior therapy that encourages clients to learn how to live a full and valued life in the moment while also experiencing difficult thoughts or feelings.

In contrast to other therapeutic models, ACT proposes that it is futile to change or control our thoughts and feelings and focuses on other processes to lead to change.

To use the acronym of ACT, this approach focuses on encouraging clients to accept that difficult experiences are a part of living, choose a direction they would like their life to move toward, and Take action to move towards their life goals.
