On the Utility and Efficacy of Acceptance and Commitment Therapy with Adults with Developmental Disorders

Saturday, October 15th, 9:00am – 12:00pm

Despite the growing body of research illustrating the efficacy of Acceptance and Commitment Therapy (ACT) with a number of clinical populations, very few published studies exist illustrating its efficacy with individuals with developmental disorders. This paucity of research is surprising given the number of verbally sophisticated adults with developmental disorders receiving behavior analytic services who are likely to show psychological inflexibility and experiential avoidance. This workshop will showcase research evaluating the efficacy of components of ACT with adults with developmental disorders, including intellectual disability, autism spectrum disorder, and dual diagnoses. Also presented will be research focused on the effects of components of ACT on the behavior of human service agency staff working with individuals with such disorders.
