“…Children with ASD typically engage in high levels of stereotypy (Bodfish, Symons, Parker, & Lewis, ; Lewis & Bodfish, ) that can interfere with the acquisition of other adaptive behavior (Koegel & Covert, ; Lang et al, ). Previous research has evaluated the effectiveness of response interruption and redirection (RIRD) as an intervention to decrease vocal stereotypy (Ahearn, Clark, MacDonald, & Chung, ; Ahrens, Lerman, Kodak, Worsdell, & Keegan, ; Cassella, Sidener, Sidener, & Progar, ; Colón, Ahearn, Clark, & Masalsky, ; Liu‐Gitz & Banda, ; Love, Miguel, Fernand, & LaBrie, ; Miguel, Clark, Tereshko, & Ahearn, ; Schumacher & Rapp, ) and motor stereotypy (Ahrens et al, ; Giles, St. Peter, Pence, & Gibson, ). Each time the participant engages in stereotypy during RIRD, the therapist interrupts stereotypy by delivering vocal (e.g., asking the participant social questions; Ahearn et al, ) or motor demands (e.g., “touch your head”; Ahrens et al, ) and redirecting behavior to comply with those demands.…”
