Treatment Integrity and Intensity: Critical Considerations for Delivering Individualized Interventions

Evaluation of any given student's responsiveness to intervention depends not only on how effective the intervention is, but also whether the intervention was delivered as intended as well as in the appropriate format and according to the most useful schedule. These latter elements are referred to as treatment integrity and treatment intensity, respectively. The purpose of this chapter is to define and describe how treatment integrity and intensity can be incorporated in the evaluation of outcomes associated with individualized intervention delivery.
