“…Challenging behavior is one of the major clinical concerns in the field of autism spectrum disorder (ASD; Sigafoos, Arthur, & O'Reilly, 2003). It is estimated that 56-94% of children with ASD engage in some types of challenging behavior including selfinjurious behavior (SIB), aggressive behavior, stereotypy, disruptive behaviors (e.g., property destruction, tantrums, noncompliance), elopement, sleep problems and feeding disorders (Didden et al, 2012;Matson et al, 2008;Rattaz, Michelon, Munir, & Baghdadli, 2018). Without appropriate intervention, challenging behavior tends to persist; chronic and severe challenging behavior can significantly hinder the child's overall development and negatively impacts family quality of life (Frantz et al, 2017;Machalicek, O'Reilly, Beretvas, Sigafoos, & Lancioni, 2007).…”
