Brief Summary
- Basic premise: ACT is about both acceptance and change. Clients are encouraged to let go of the struggle to change unwanted thoughts and emotions; instead focusing on the present moment and acting on what the client values most.
- Essence of therapy: Acceptance and Commitment Therapy (ACT), a behavioral therapy based on Relational Frame Theory, aims to change the relationship individuals have with unwanted or feared thoughts, feelings, memories, and physical sensations. Acceptance and mindfulness strategies are used to teach clients to decrease avoidance, attachment to cognitions, instead increasing focus on the present and psychological flexibility. Clients learn to clarify their goals and values and to commit to behavioral change strategies.
- Length: approx. 12 sessions
