There has been growing interest in Acceptance and Commitment Therapy (ACT) within the applied behavior analytic community for use with multiple populations. ACT may be an appropriate intervention framework when working with verbally advanced individuals whose verbal behavior (i.e., rule governed behavior) participates in behavior patterns that are inconsistent with their chosen values. We will review ACT as it can be implemented by Board Certified Behavior Analysts (BCBAs) with an emphasis on the on-going interaction between behavior and context. The theoretical underpinnings of ACT are derived from well-established behavioral theories and applied research is well underway. We will also review a brief ACT functional analytic framework from which to guide ACT interventions when implemented by behavior analysts.
