A Family-Centered Positive Behavior Support Approach to the Amelioration of Food Refusal Behavior

Abstract

The purpose of this study was to evaluate the effectiveness of a family-centered positive behavior support approach to the amelioration of food refusal behavior in a child with autism. The study was conducted with the child and his family in their home. It employed an empirical case study design with one meal routine: snack time. Following training and support with the child's mother, results show high levels of child food acceptance, successful child participation in observed snack routines, and high parental ratings of social validity and contextual fit. Improvements maintained up to 26 months postintervention. Implementation also was associated with generalization of the child's eating behavior to new foods and to his father's supporting him during snack time. Child behavioral improvements also were associated with parental reports of gains in family quality of life. Results are discussed in terms of implications for practitioners and researchers involved in behavioral feeding interventions.
