Efficacy of functional analysis for informing behavioral treatment of inappropriate mealtime behavior: A systematic review and meta-analysis

Abstract

Children diagnosed with a feeding disorder often exhibit inappropriate mealtime behavior such as throwing or swiping food, which can exacerbate feeding difficulties during treatment. We conducted a meta-analysis of 86 behavioral treatments for inappropriate mealtime behavior from 23 studies to assess the extent to which treatments based on a pretreatment functional analysis were more efficacious than those treatments not based on a functional analysis. Procedural escape extinction and attention extinction for inappropriate mealtime behavior, as well as differential reinforcement for food acceptance or consumption, represented the most common treatments independent of whether a functional analysis was conducted. No difference was detected between treatments that were and were not based on a functional analysis, and mean effect size across measures was identical (79%). The requirement of a pretreatment functional analysis for inappropriate mealtime behavior is equivocal given that standard care often includes efficacious treatment components that are not informed by a functional analysis.
