Interactive Behavior Therapy (IBT) is an evidence-based group intervention for adults with intellectual disabilities that has been shown to help participants decrease target behaviors such as inappropriate sexual behavior, depressive symptoms, anxious responses to trauma, and negative symptoms of Schizophrenia. It has also been shown to increase social skills. Although developed by psychologists who do not come from a behavior analytic background, the therapeutic processes are easily explained by basic behavior analytic concepts. In this presentation, we will introduce the IBT paradigm and offer alternative behavior analytic explanations for behavioral progress shown by participants. Resources for further reading are also provided for those who may be interested in incorporating IBT methods into the social skills groups.
