“…These methods use behavioral strategies (e.g., direct prompting, contingency reinforcement) to teach specific social-communication skills along with emphasizing strategies derived from developmental science designed to facilitate reciprocity, social engagement, and shared affect during adult-child interactions. Child progress across several domains has been documented in two randomized trials (Rogers, & Dawson, 2009; Yoder & Stone, 2006) and controlled single-subject and quasi-experimental studies of systematic blending of behavioral/developmental methods (Ingersoll & Dvortcsak, 2010; Ingersoll, Dvortcsak, Whalen, & Sikora, 2005; Ingersoll & Wainer, 2013;). Given this empirical support, parent-mediated NDBIs are increasingly recommended as state-of-the-art treatment options for children at risk for developing ASD (Dawson et al, 2010; Ingersoll, 2009; Rogers et al, 2012; Stahmer, Schreibman, & Cunningham, 2011).…”
