An Evaluation of the Prevent-Teach-Reinforce Model within a Multi-Tierred Intervention System

This study assessed the Prevent-Teach-Reinforce (PTR) model to determine its impact on problem and replacement behaviors of three children who are typically developing with behavioral challenges in a high-need elementary school setting. Specifically, this study evaluated the use of the PTR model as an intensive individualized Tier 3 intervention within a multi-tiered intervention system. In addition, the study examined the validity and usability of the Individualized Behavior Rating Scale Tool (IBRST), which was developed as a feasible daily progress monitoring tool in conjunction with the PTR model. Social validity and fidelity of intervention implementation were also assessed. A multiple baseline across participants was employed to evaluate the impact of implementation of the model on the children\u27s behaviors. The results of the study indicated that the PTR model was effective in reducing problem behaviors and increasing the use of replacement behaviors for all three participants. In addition, the IBRST completed by the teachers was found to have a substantial correlation to data collected during direct observations
