Acceptance and Commitment Therapy (ACT) is related to CBT, but focuses on mindfulness, acceptance, and committed action towards personal values.

ACT (pronounced like the word “act”) relies on a term called “psychological flexibility”, which helps clients change their relationships to their thoughts, connect with the present moment, and make behavior choices that serve their values. Therapists use talk therapy and experiential exercises to identify avoidant behavior and build tolerance for sitting with pain, discomfort, and uncertainty - all of which are essential human experiences.
