The present study examined the effects of Acceptance and Commitment Therapy (ACT) as a core behavior modification method on students with severe behavior disorders. A pre/posttest design was implemented and both control and treatment groups were exposed to testing measures. Students in the treatment group were exposed to ACT as well as contingency based classroom management, and a token economy in an attempt to increase grade point average (GPA), days in attendance, and psychological flexibility. Results are discussed regarding the increase in GPA and attendance, and levels of psychological flexibility are also elaborated upon. Limitations, implications, and future research are also discussed.
