Clinical Correlates and Prevalence of Food Selectivity in Children with Autism Spectrum Disorder.

OBJECTIVE: To examine clinical correlates and prevalence of food selectivity (FS) - ie, self-restricted diet, reluctance to try new foods - in children with autism spectrum disorder (ASD) ascertained from a general outpatient autism clinic. STUDY DESIGN: A multidisciplinary team (pediatric nurse practitioner, psychologist and dietitian) assessed medical and psychosocial histories and dietary habits in 103 children with ASD (mean age = 5.8 ± 2.2 years; range 2-10). Parents rated child mealtime behavior on the Brief Autism Mealtime Behavior Inventory (BAMBI) and disruptive behavior on the Aberrant Behavior Checklist (ABC). Height and weight measurements were collected. Children were classified as FS or no FS based on parent reported intake and mealtime behavior. A 24-hour dietary recall was used to record intake percentages < 80%. Logistic regression and multivariable modeling were used to evaluate clinical correlates with FS. RESULTS: Of 103 children, 45.6% (n = 47) were classified as FS; 54.4% (n = 56) no FS. After adjusting for potential confounders, the odds of FS increased by 1.91 (95% CI: 1.38, 2.64, P < .001) for every half-SD increase in BAMBI total score and by 1.35 (95% CI: 1.05, 1.74, P = .020) for every half-SD increase in ABC Hyperactivity/Noncompliance. No group differences in anthropometrics or nutritional intake were identified. CONCLUSIONS: Food selectivity (FS) in children with ASD was strongly associated with greater severity of disruptive mealtime and hyperactivity/noncompliance behaviors. FS was not associated with anthropometrics or nutritional intake.

A retrospective analysis of the relation between resurgence and renewal of behavior targeted for reduction.

Functional communication training (FCT) is an evidence-based treatment for behavior targeted for reduction that often combines extinction for target responses and arranges functionally equivalent reinforcement for alternative behavior. Long-term effectiveness of FCT can become compromised when transitioning from clinic to nonclinic contexts or thinning reinforcement schedules for appropriate behavior. Such increases in targeted behavior have been conceptualized as renewal and resurgence, respectively. The relation between resurgence and renewal has yet to be reported. Therefore, the present report retrospectively analyzed the relation between renewal and resurgence in data collected when implementing FCT with children diagnosed with developmental disabilities. We found no relation when evaluating all 34 individuals assessed for resurgence and renewal or a subset of individuals exhibiting both resurgence and renewal. These findings suggest that one form of relapse may not be predictive of another form of relapse.

Evaluation of two physical guidance procedures in the treatment of pediatric feeding disorder.

Children with pediatric feeding disorder may refuse to consume an adequate variety and/or volume of food to maintain expected growth. They can consume food but may actively or passively refuse, resulting in escape or avoidance of eating. Behavioral interventions like positive reinforcement with escape extinction can increase consumption. However, sometimes these interventions are insufficient, especially in treating passive refusal. In these cases, physical guidance may be used to prompt an open mouth to deposit food. Research indicates open-mouth prompts are effective and rated as acceptable. This study replicated an existing physical guidance procedure, the finger prompt, and compared its efficacy and acceptability with that of a spoon prompt. This study extended research by defining and measuring passive refusal as a dependent variable and assessing social validity among different stakeholders and times. Both prompts were effective in treating food refusal, and caregivers rated the finger prompt as more preferred.

A Retrospective Consecutive Controlled Case Series of Underspoon: A Modified-Bolus Placement to Address Behavior That Interfere With Swallowing.

Children diagnosed with pediatric feeding disorder (PFD) or avoidant/restrictive food intake disorder (ARFID) may present with comorbid oral-motor delays that often contribute to their failure to consume an adequate volume and/or variety of foods. Once the food enters the mouth, these children may exhibit additional problematic behavior such as expulsion and packing that further averts oral intake. Previous research has evaluated the impact of modified-bolus placement methods, including flipped spoon and NUK® brush, in comparison to upright spoon on expulsion and packing. Whether responses are due to performance or skill deficits, researchers hypothesize that modified-bolus placement may assist with reducing the response effort associated with swallowing. This retrospective consecutive controlled case series assessed the clinical application of an additional modified-bolus placement method, underspoon, to increase food consumption and decrease problematic behavior that interfere with mouth clean for children with PFD or ARFID.

Treatment of Feeding Concerns in Children With Autism Spectrum Disorder: A Systematic Review of Behavioral Interventions With Caregiver Training.

Successful feeding intervention ultimately requires generalization and adoption of treatment into the home. Treatment models, however, differ regarding how and when caregivers are integrated into care delivery process. Some treatments involve a primary model of parent training with caregivers serving as co-therapist at the onset of intervention, while others involve a complimentary model where a therapist delivers the intervention and caregiver training occurs once the child's behavior is stable. This review systematically evaluates the evidence-base regarding behavioral feeding intervention for children with autism spectrum disorder (ASD), with a specific focus on interventions involving parent training. Results provide further evidence regarding the potential benefits of behavioral intervention to improve feeding concerns in ASD, while also highlighting growing attention to documenting and/or evaluating parent training within the treatment literature. Important questions remain regarding factors guiding the use of a primary or complimentary model of parent training.

Multidisciplinary feeding treatment for a patient with interstitial lung disease.

Children with underlying medical and developmental conditions often present with complications that include feeding difficulties. Severe feeding difficulties may meet the criteria for the psychiatric diagnosis of Avoidant Restrictive Food Intake Disorder (ARFID). ARFID is a disruption in feeding/eating which may include weight loss/faltering growth, nutrient deficiencies, and/or reliance on a nutritionally complete formula to meet caloric needs. Children with interstitial lung disease (ILD), have a higher prevalence of feeding problems than the general population. To date, no published literature exists to provide guidance for treating severe feeding difficulties experienced by children with ILD. In this paper, we present an encounter in which we safely and effectively treated ARFID as evidenced by underweight and dependence on a nutritionally complete formula in a 3-year-old male with ILD using a multidisciplinary approach to treatment. Before the admission, the patient relied primarily on oral nutritional supplementation for most of his nutritional needs and therapeutic efforts to advance food intake were complicated by mealtime behavior problems and concerns regarding swallow safety. Intervention introduced 16 new foods, established consistent caloric intake of target food, and successfully weaned the patient from bottle feeding. We also review special considerations and provide guidelines for adapting treatment at multidisciplinary programs for patients with complex cardiorespiratory disease including modifications to behavior management procedures, medical monitoring, and nutritional consultation.

Behavior Analysis Goes to School: Teacher Acceptability of Behavior-Analytic Language in Behavioral Consultation.

Effective communication is a vital component of behavioral consultation. Behavioral consultants (e.g., behavior analysts, school psychologists) are responsible for drafting behavior intervention plans, delivering accessible training, and providing concise and consumable feedback to teachers. Their reliance on technological descriptions to communicate behavioral principles and procedures may yield poor social validity and hinder the consultant-teacher relationship. In this study, we recruited 164 teachers through Amazon Mechanical Turk and administered a survey to (a) evaluate the social acceptability of technical and nontechnical language used in behavioral consultation across a variety of student populations and (b) gain information about teachers' experiences with behavioral consultation. Implications are discussed for training and the provision of behavioral consultation services.

A systematic review of physical guidance procedures as an open-mouth prompt to increase acceptance for children with pediatric feeding disorders.

This article reviews behavioral treatments of pediatric feeding disorders using physical guidance procedures as an open-mouth prompt (i.e., jaw prompt, finger prompt, Nuk prompt, side deposit) to increase food acceptance. We identified 9 articles containing 35 systematic evaluations. We coded participant and study characteristics and assessed the experimental rigor, quality, and outcomes of each evaluation. Of the high-quality research present, the finger prompt variation and side deposit reliably increased acceptance. We found mixed results on the efficacy of the jaw prompt, although it was the most widely researched procedure. Further, authors reported interobserver agreement for 100% of the participants, procedural integrity for 60%, social validity for 80%, fading for 5%, and follow-up for 55%. Based on the invasive nature of physical guidance, we provide recommendations for researchers and clinicians to increase the quality of their treatment evaluations. We discuss limitations, implications for practice, and future research.
