Acceptance and Commitment Therapy (ACT) is one of the recent mindfulness-based behaviour therapies. It has been shown to be effective with a range of mental health difficulties. Importantly, ACT assumes that the psychological processes of a normal human mind can be destructive and create psychological suffering. Symptom reduction is not a goal of ACT, based on the view that ongoing attempts to get rid of symptoms can create mental health problems in the first place.

ACT has two core messages: accept what is out of your personal control and commit to action that improves and enriches your life. The aim of ACT is to maximise human potential for a rich, full and meaningful life. ACT does this by teaching us psychological skills to deal with painful thoughts and feelings effectively. It also helps us to clarify what is truly important and meaningful – in other words, our values. It then uses that knowledge to guide, inspire and motivate us to change our lives for the better.
