Acceptance and Commitment Therapy is a method of treating mental health issues that is not measured by "symptom reduction". This surprises patients and therapists alike. Instead, the goal of this therapy is what experts call "psychological flexibility". Although symptoms tend to reduce as a byproduct of the treatment, psychological flexibility refers to making the patient more resilient to unpleasant thoughts, emotions, and distress.

A trained therapist can help you identify the obstacles that are leading to your distress. Acceptance and Commitment Therapy can help you distinguish yourself from your thoughts and emotions while making dedicating choices and commitments towards your valued goals. At the same time, we focus on being mindful and fully experience the present, rather than avoiding and pushing away things that are unpleasant.
ACT challenges patients to approach and engage with, rather than avoid, unpleasant thoughts and emotions. This helps bring an end to the "inner civil war" that patients experience where they attempt to combat with their own feelings and thinking. The question becomes, could I have this unpleasant thought or feeling, and choose to act on my values instead?
