Our purpose in this systematic review was to identify, evaluate, and summarize the single-case research design studies examining behavioral interventions to address self-injurious behavior for young children with autism spectrum disorder. We identified 24 studies published between 2000 and 2016 that met the inclusion criteria. We reviewed and coded each study across five content areas using systematic procedures. These content areas consisted of the methodological quality of single-case research designs, children's demographic information, conditions under which the intervention was implemented, characteristics of intervention, and outcomes. Our findings indicate that procedural integrity data were reported for only one study and social validity for two studies. The majority of studies were implemented by researchers or therapists in the school setting. For 24 of 30 children included in the studies reviewed, the authors taught a replacement behavior selected on the basis of an assessment conducted prior to intervention. All authors reported a decrease in the self-injurious behavior post-intervention. A limited number of authors examined generalization and maintenance of low rates of self-injurious behavior. Limitations of the present review and future directions and implications for research and practice are discussed.

Our primary purpose in this study was to examine the structure of a response class when new members are acquired through mand training. To do this, we replaced existing mands (e.g., reaching) in three children with autism with two new functionally equivalent mands. Next, we examined their responding under immediate- and delayed-reinforcement conditions. Then, we assessed generalization to novel social partners. We employed a reversal design to examine the effectiveness of mand training and to assess responding under both immediate- and delayed-reinforcement conditions. Our results suggest that all children acquired the new mands and that two of the children emitted these responses as replacements when the social partner did not provide access to the reinforcer contingent on the child's first mand. Generalization data indicate that all three children emitted the new mands and two of the children alternated between the new mands with novel social partners. We discuss the clinical implications and the conceptual significance of teaching multiple replacement mands to children with autism and severe language delays.

In this study, we extended the literature on negatively-reinforced mands by teaching multiple novel, socially appropriate alternative mands to two young children with autism spectrum disorder (ASD). First, we replaced existing mands (e.g., pushing away) with two novel, socially appropriate, negatively-reinforced mands. Next, we examined responding under immediate- and delayed-reinforcement conditions to assess resurgence to existing mands and to determine whether the function of the communicative behavior influences the consistency with which different mands are emitted. Finally, we examined generalization to different social partners. Our data suggest that both children acquired the new mands and used them to avoid nonpreferred items. Resurgence to existing mands during delayed-reinforcement conditions was documented for one child, and the sequence in which mands were emitted within a response class was not influenced by the function of the communicative behavior. Generalization data indicate that both children emitted the new mands and one of the two children alternated between the two mands with a social partner who was not involved in the training. We discuss the importance of teaching multiple negatively-reinforced alternative mands to children with autism in applied settings.
