“…In other words, procedural fidelity may be determined by how closely an interventions' implementation matches its' written description. Whereas, earlier reviews of empirical studies showed that only 15.8% (Gresham, Gansle, & Noell, 1993a), 14.9% (Gresham, Gansle, Noell, Cohen, & Rosenblum, 1993b) and 18% (Wheeler, Baggett, Fox, & Blevins, 2006) of studies defined, analyzed, and reported treatment fidelity data; a more recent review and analysis (Barnett et al, 2013) showed increased emphasis on treatment fidelity, reporting that 70% of their pool of 266 school-based research articles published between 2005-2012 included fidelity of intervention data.…”
