"Learning ACT," provides a detailed guide for therapists in understanding and applying Acceptance and Commitment Therapy (ACT). Rooted in contextual behavioral science (CBS) and Relational Frame Theory (RFT), the book outlines ACT's core principles, which emphasize psychological flexibility over symptom reduction. It meticulously explains six key flexibility processes through theory, practical exercises, and client dialogues, focusing on undermining experiential avoidance and cognitive fusion, fostering present moment awareness, cultivating a sense of self-as-context, clarifying values, and promoting committed action. The text encourages therapists to personally engage with ACT principles and develop core competencies to effectively guide clients toward living rich and meaningful lives despite the presence of difficult thoughts and feelings.
