The purpose of this study was to establish the I ASSIST as an appropriate and effective behavior management tool in dealing with emotionally disturbed youth. Trained staff were observed during daily interactions with youth and the content of these interactions was documented. The time of non-compliance was recorded as well and was examined in respect to how the I ASSIST was implemented, if at all. A review of the literature created a foundation for different methodologies in behavior management. This study showed that there is no significant difference in time of non-compliance in relationship to number of steps of the IASSIST that were successfully implemented during the interaction. The study also showed the importance of setting clear preliminary expectations for clients in reducing disruptive behavior.
