Acceptance and Commitment Therapy

Also written as: ACT — Acceptance and Commitment Therapy

A behavioral intervention that uses mindfulness and acceptance strategies alongside commitment to value-based actions.

Full Definition

Acceptance and Commitment Therapy (ACT) is a form of psychotherapy that combines mindfulness-based strategies with behavior change techniques. Rather than trying to eliminate difficult thoughts and feelings, ACT focuses on accepting them while committing to actions that align with personal values. The therapy emphasizes psychological flexibility as a core outcome measure. ACT is widely used in behavioral medicine for chronic pain, addiction, and anxiety disorders. Documentation often includes values clarification exercises and mindfulness protocols.
