Abstract
The current study evaluated the effectiveness of a behavior contract, used in conjunction with nutrition education and a self-monitoring component, to manage portion control of a 17-year-old female with autism spectrum disorder (ASD). The behavior contract specified a reinforcement contingency for meeting a weekly goal that described how many servings the participant may consume but should not exceed during meals consisting of target foods. During each meal, the participant used a food diary to record number of servings consumed and whether or not they met their goal for that meal. Results of the study demonstrated that the use of a behavior contract was successful in managing the number of portions the participant consumed. Additionally, the participant adhered to their daily goals during generalization sessions which suggests that the skill taught generalized to other naturalistic contexts.
