The statistical precision by which intervention outcomes are evaluated has increased in recent years in an effort to improve their viability in addressing emotional, social, behavioral, and academic issues. Despite these advances, treatment integrity, a vital aspect in evaluating the merit of a given intervention, remains largely overlooked. Definitions of treatment integrity include the accuracy and consistency with which an intervention is implemented (Wolery, 2011) and whether the intervention is delivered as intended (Knoche, Sheridan, Edwards, & Osborn, 2010). For our purposes, we share the perspective of Dane and Schneider (1998), who defined treatment integrity as the extent to which treatment agents deliver an intervention as intended with sufficient precision, reliability, and distinction.
