“…Individuals with developmental disabilities frequently require behavioral intervention, with researchers estimating that 48% to 82% of individuals with developmental disabilities exhibit problem behavior (Lecavalier, 2006;Poppes, van der Putten, & Vlaskamp, 2010;Rojahn, Matson, Lott, Esbensen, & Smalls, 2001). More recently, Weiss, Ting, and Perry (2016) found that 40.4% of a sample of children with severe developmental disabilities, including ASD, exhibited serious maladaptive behavior. Common problem behaviors observed in school settings include temper tantrums, arguing, and defiance, with behaviors such as self-injury and refusing to talk occurring in a substantial number of individuals (Lecavalier, 2006).…”
