A new and comprehensive Parent Mealtime Action Scale (PMAS) was developed to identify dimensions of mealtime behaviors used by parents, then examined for its usefulness to explain variance in children's diet and weight status. Exploratory factor analysis with 2008 mothers and two confirmatory factor analyses with 541 mothers and 439 fathers produced a(More)
The present study examined the effectiveness of the Kid's Choice Program (KCP) for increasing children's weight management behaviors, and decreasing body mass index percentile (BMI%) for overweight and average-weight children. It also evaluated KCP characteristics relevant to long-term application in schools. Participants included 382 children assigned to(More)
The "Kids Choice" school lunch program used token reinforcement, food choice, and peer participation to increase children's fruit and vegetable consumption without later drops in food preference sometimes found in past research and often called 'overjustification effects.' Participants included 188 school children (92 boys, 96 girls; mean age = 8.0; 95%(More)
Extinction and reinforcement contingencies were used to treat 2 children with feeding disorders. Positive reinforcement and avoidance extinction effectively increased food acceptance but also increased food expulsion. Reduced expulsion and increased swallowing were achieved by repeated presentation of expelled food, a second extinction component
Children with feeding disorders often display severe food selectivity. For many of these children, consuming highly textured foods may be aversive or potentially dangerous because of frequent gagging. The purpose of this study was to demonstrate the efficacy of texture fading in the treatment of food selectivity displayed by 4 children. Treatment involved(More)
Food refusal is a severe feeding problem in which children refuse to eat all or most foods presented and exhibit problems with growth. This review discusses the definition, etiology, and interventions pertaining to food refusal. The interventions utilized for food refusal typically consist of several treatment components. These treatment components are(More)
The present study evaluated parent mealtime actions that mediate associations between children's fussy-eating and their weight and diet. Participants included 236 feeding-clinic children in three diagnostic groups: 50 with autism, 84 with other special needs, and 102 without special needs. Children's weight was measured as body mass index percentile (BMI%),(More)
Feeding problems are common among children with autism spectrum disorders (ASD), but the assessment of feeding behavior in this population has received little attention. Currently, two of the most promising psychometric assessments of feeding problems in children and adolescents with ASD are the Brief Autism Mealtime Behavior Inventory (BAMBI) (Lukens and(More)
The present study evaluated the 23-item Screening Tool for Feeding Problems (STEP; Matson & Kuhn, 2001) with a sample of children referred to a hospital-based feeding clinic to examine the scale's psychometric characteristics and then demonstrate how a children's revision of the STEP, the STEP-CHILD is associated with child and parent variables.(More)
OBJECTIVE A structured intervention was used to teach chewing to two children with special needs. Neither child had a history of chewing or eating high-textured food. METHOD The intervention combined oral-motor and behavior components to teach chewing. A multiple baseline design was used to evaluate treatment effectiveness. RESULTS Both children(More)
