A comparison of simultaneous versus sequential presentation of novel foods in the treatment of food selectivity

Abstract

The present study extended the literature on feeding disorders by conducting a comparison of sequential and simultaneous food presentation in the treatment of food selectivity. In the simultaneous condition, a highly preferred food was presented in the same bite with a non-preferred food (NPF), and during the sequential condition, a highly preferred food was delivered as a consequence for acceptance and consumption of NPFs. Generalization and maintenance of food consumption was assessed. Although results for two participants indicated that both presentation methods produced an increase in acceptance and consumption of NPFs when combined with an escape extinction procedure, anecdotal observations suggested that participants may have had a preference for eating foods in a sequential fashion.

Observation and Comparison of Mealtime Behaviors in a Sample of Children With Avoidant/Restrictive Food Intake Disorders and a Control Sample of Children With Typical Development

“…Poor intake, including number of food bites or volume of food eaten and associated avoidant behaviour towards food and/or mealtimes (Arvedson, 2008;Binnendyk & Lucyshyn, 2009;Casey et al, 2009;VanDalen & Penrod, 2010;Woods, 2010) have been consistently observed in home and laboratory studies. This suggests that reduced food intake is a key characteristic of disordered feeding behaviour in childhood, and indeed an ARFID diagnosis will be unequivocal in children requiring supplementary or total tube-feeding in the absence of physical cause.…”

A comparison of two multicomponent treatment packages for food refusal

“…This study demonstrated that DRA and EE was more effective than RC, EE, and DRA for improving the participant's bite and drink consumption, IMB, and total gram intake. It adds to the research literature evaluating different treatment packages for treating food refusal and selectivity in children (Addison et al, ; Fernand et al, ; Piazza et al, ; Seiverling et al, ; Van Dalen & Penrod, ) as it directly compares these two treatment packages. No differences were observed in child responding between treatments until after the empty spoon condition.…”

“…A few studies have compared the effectiveness of different multicomponent packages on child mealtime behavior directly (Addison et al, ; Fernand, Penrod, Fu, Whelan, & Medved, ; Piazza et al, ; Seiverling, Harclerode, & Williams, ; Van Dalen & Penrod, ). Piazza et al () compared two behavioral interventions, simultaneous presentation (i.e., preferred foods presented at the same time as the nonpreferred food) and sequential presentation (i.e., presentation of preferred food after acceptance of the nonpreferred food) on acceptance of nonpreferred foods in three children with food selectivity and pervasive developmental disorder.…”
