Functional analysis screening for inappropriate mealtime behavior

Abstract

AbstractInappropriate mealtime behavior (IMB) is a class of food refusal behavior that is commonly observed in children with neurodevelopmental disorders or avoidant/restrictive food intake disorder. An abundance of research has demonstrated that IMB is commonly maintained by negative reinforcement in the form of escape from food or drink presentation. Given the common association between IMB and escape as a reinforcer, more efficient methods of conducting functional analyses have been called for. The present study examined the extent to which indirect assessments and a functional analysis screening process reliably predicted an escape function in three children with autism spectrum disorder who engaged in IMB. The results of the two assessments were then compared to a standard functional analysis. For all participants, the functional analysis identified an escape function, which corresponded with both the indirect assessment and screening. Additionally, within‐session analyses of screening sessions further validated the screening process. The functional analysis screening of IMB is discussed in terms of its efficiency, practicality, and experimental design. The results of this study offer a framework for efficiently assessing the function of IMB, while providing recommendations for future research.
