--- - |2 This study evaluated behavioral skills training (BST) and in situ training (IST) to teach a response to bullying (RtB) to four adults with intellectual disabilities who were victims of bullying. The RtB consisted of refraining from retaliating, stating disapproval, walking away, and telling a staff member. In situ assessments were conducted in the natural setting to assess the effects of BST and IST. BST alone was successful in teaching the RtB to two participants. When BST did not result in the use of the RtB, IST was effective for one participant, and IST plus an incentive was effective for the other participant. The results of this study are consistent with previous BST and IST research. - Journal of Applied Behavior Analysis, EarlyView.
