In this symposium, the efficacy of various interventions designed to increase consumption of non-preferred foods as well as promote self-feeding are examined with children with food selectivity. Studies included in this symposium evaluated antecedent-based interventions such as modeling, and different applications of escape extinction combined with differential reinforcement. Mechanisms responsible for behavior change and directions for future research are discussed. Further, contextual factors that may play a role in the differential effectiveness of antecedent interventions are examined.

Evaluation of Two Extinction Procedures During Feeding Protocols: Non-removal of the Spoon and 3-Step Prompting

Several studies have examined non-removal of the spoon (NRS) and 3-step prompting (3P) to increase non-preferred food consumption; however, there is limited research on how these methods increase or promote self-feeding of non-preferred foods. Self-feeding is an important aspect of feeding programs as it promotes independence. The purpose of the current study was to investigate and compare the effectiveness of two methods (i.e., NRS and 3P) used with differential reinforcement of alternative behavior to increase self-feeding of non-preferred foods and non-preferred food consumption or acceptance for children with food selectivity. In addition, side effects during each procedure (e.g., crying, spitting, etc.) were assessed. Due to the varied results from participants, results are still inconclusive as to which method is more effective at promoting self-feeding of non-preferred foods. Suggestions for future research are discussed.

|Abstract: Previous research has supported that the modeling procedure may be a viable treatment procedure for children who have feeding disorders (Greer et al., 1991). The current study extended previous research on modeling by investigating the effectiveness of two different modeling procedures (i.e., modeling food consumption and differential reinforcement, and modeling food refusal and escape extinction) on food consumption of three participants with food selectivity, while addressing limitations of previous research. Results suggested that modeling food consumption and differential reinforcement was effective in increasing initial consumption of one food for Larry, and modeling food refusal and escape extinction was effective in increasing initial consumption of two foods for Larry, and one food for Adam. Neither modeling procedure was effective in increasing initial consumption for Sally. Possible mechanisms responsible for the effectiveness of the modeling procedure as well as limitations and directions for future research are discussed.|

Behavior analytic feeding researchers have found that escape extinction procedures are often a necessary component of effective behavior intervention plans. These procedures may involve a number of side effects, however, and are not practical in many settings (e.g., in home-based settings it is difficult to prevent a child from avoiding a bite). Moreover, extinction procedures are not always necessary. In fact, there now exist several strategies, considered antecedent in nature, which have been found to be effective in the absence of escape extinction. It is possible that an analysis of contextual factors, which are often underemphasized in behavior analytic research (especially that published in popular behavioral journals), participate in the differential success of antecedent strategies. This review examines recent research in the Journal of Applied Behavior Analysis (2000-2012) that evaluates antecedent interventions. We found the intensity of the feeding problem and presence of feeding-related medical conditions were related to the differential success of antecedent interventions.
