“…To date, effective interventions for challenging behavior support the use of functional analysis and behavioral interventions based in the science of applied behavior analysis (ABA; Baer, Wolf, & Risley, 1968;Cooper, Heron, & Heward, 2007;Emerson et al, 2001;Iwata, Dorsey, Slifer, Bauman, & Richman, 1994). Function-based interventions including noncontingent reinforcement (providing reinforcers on a fixed-time schedule to decrease motivation to engage in challenging behavior), teaching appropriate behavior (i.e., functionally-equivalent replacement behavior), positive reinforcement contingent on appropriate behavior, extinction (withholding consequences for challenging behavior), and positive and negative punishment strategies have documented effectiveness in significantly reducing challenging behavior (Davis & Rispoli, 2018;Erturk, Machalicek, & Drew, 2018;Mulligan, Healy, Lydon, Moran, & Foody, 2014). Caregivers' involvement in treatment plays a critical role in generalizing and maintaining treatment outcomes in natural settings, and caregivers can implement behavioral treatment with high fidelity to improve the child's challenging behavior (Gerow et al, 2018;Lang et al, 2013).…”
