Rapid eating is a common and potentially dangerous behavior among individuals diagnosed with autism spectrum disorder (ASD; Favell et al. Behavior Modification, 4 , 481–492, 1980 ). Although limited research has shown efficacy in treating rapid eating using procedures that increase interresponse time between bites, the literature on preassessment methods to inform treatment remains limited. Therefore, the purpose of the present study was to replicate and extend procedures used by Page et al. Behavior Analysis in Practice, 10 , 87–91 ( 2016 ) to effectively reduce the rapid eating of an adolescent male diagnosed with ASD through the incorporation of a preassessment and treatment package including a vibrating pager, vocal rule, and response blocking. Overall, results of the study demonstrated that the preassessment was effective in determining foods to be included in treatment, and the treatment package was effective in increasing average interresponse time between bites. Additions to the current literature as well as limitations to be addressed in future research are discussed.
