In The Oxford Handbook of Acceptance and Commitment Therapy, Michael P. Twohig, Michael E. Levin, and Julie M. Petersen bring together contributions from the world's leading scholars to create a comprehensive volume on established areas of ACT. The Handbook presents the first scholarly review of the treatment as it has developed over the past two to three decades. Featuring 33 chapters on key aspects of the treatment, the contributors offer analysis on ACT's conceptual and theoretical underpinnings, applications to specific populations and problems, methods of implementation, and other special topics. They will further cover theory, empirical support, and scholarly descriptions of treatment application.
