RESUMEN
Increased demand for applied behavior analysis (ABA) services has increased the need for additional masters-level practitioners and doctoral-level academicians and clinical directors. Based on these needs, the University of Nebraska Medical Center's (UNMC) Munroe-Meyer Institute has developed a PhD program. The academic structure at UNMC allowed us to create our PhD program in a relatively quick and efficient manner. Our PhD program has many unique features, including (a) close integration of didactic instruction with clinical and research training provided by leading experts in ABA in which students immediately apply concepts introduced in the classroom during coordinated clinical and research practica; (b) structured grant writing training in which students learn to write and submit an NIH-level grant;
RESUMEN
Self-feeding with utensils represents an important step in a child's progression toward age-typical eating and emerges in the absence of intervention for most children. In contrast, children with feeding disorders may lack the skill or motivation to self-feed, which impedes progress toward age-typical eating. In the current study, experimenters used a multielement design to evaluate negative reinforcement in the form of meal termination to transition six participants with a feeding disorder from caregiver-fed to self-fed bites and drinks. Caregivers conducted meals in which they fed the participant or prompted them to self-feed. During self-fed meal-termination sessions, participants had the opportunity to end the meal contingent on self-feeding the presented bite(s) or drink(s). Self-feeding increased during meal-termination sessions for all participants. The experimenters discuss these results relative to their potential to inform interventions for children with feeding disorders that progress the child toward age-typical eating.
RESUMEN
Visual inspection is the traditional method behavior analysts use to interpret functional-analysis results. Limitations of visual inspection include lack of standardized rules, subjectivity, and inconsistent interrater reliability (Fisch, 1998). To address these limitations, researchers have developed, evaluated, and refined structured criteria to aid interpretation of functional analyses of destructive behavior (Hagopian et al., 1997; Roane et al., 2013; Saini et al., 2018). The current study applied the structured criteria Saini et al. (2018) described to functional analyses of inappropriate mealtime behavior. We assessed its predictive validity and evaluated its efficiency relative to 3 post hoc visual inspection procedures. Validity metrics were lower than those in Saini et al. however, ongoing visual inspection increased the efficiency of functional analyses by more than 30%. We discuss these findings relative to the procedural differences between functional analyses of destructive behavior and inappropriate mealtime behavior.

Previous literature supports the use of functional analyses to prescribe treatments for children with feeding disorders (Bachmeyer et al., 2009). Nevertheless, clinicians often train caregivers to use healthy contingencies, independent of whether those contingencies are function based. However, it is unclear whether including nonfunction-based contingencies differentially affects inappropriate mealtime behavior. In the current investigation, the caregivers of 3 children with feeding disorders provided escape from bites and drinks and attention following inappropriate mealtime behavior. Results of a functional analysis showed escape from bites or drinks, but not attention, reinforced inappropriate mealtime behavior. We then tested the effects of escape extinction when the feeder either provided or withheld attention following inappropriate mealtime behavior. Inappropriate mealtime behavior decreased and acceptance increased when the feeder implemented escape extinction independent of whether they provided or withheld attention. We discuss the implications of including nonfunction-based components in the treatment of pediatric feeding disorders.

Renewal, the increase in behavior during extinction following context changes, may be particularly concerning during intervention for feeding disorders because context changes are often necessary for intervention generality and maintenance (Podlesnik et al., 2017). In the current study, we tested for renewal and evaluated a renewal-mitigation procedure when we transferred intervention from a therapist to a caregiver, from clinic to the home, and changed the foods the feeder presented. We used an ABA arrangement to evaluate the generality of the renewal effect with 7 participants who engaged in inappropriate mealtime behavior. Context A was functional reinforcement. Context B was function-based extinction during the control and mitigation conditions and our renewal-mitigation procedure in the mitigation condition. The renewal test was function-based extinction in Context A. We observed renewal of inappropriate mealtime behavior in 4 of 7 participants, and our renewal-mitigation procedure was effective for 4 of 4 participants.

CASE: Sam is a 20-year-old young man with intermittent gastritis, autism spectrum disorder, and intellectual disability who was admitted to the hospital because of nutritional concerns. His parents have legal guardianship and report that he has had increasing frequency of refusal to eat, resulting in a 15-pound weight loss over the past 3 months. On admission, a multidisciplinary team including specialists in gastroenterology, nutrition, feeding (behavioral and mechanical), psychiatry, palliative care, and social work was engaged to develop an evaluation and care plan. Sam's nutritional assessment was significant for severe malnutrition. An upper endoscopy was performed and was without abnormalities, including signs of significant gastritis.An upper endoscopy was performed and was without abnormalities, including signs of significant gastritis.A carefully obtained history found that Sam does not have a primary care physician. He was recently hospitalized at another facility because of his weight loss and nutritional concerns but was discharged against medical advice because of parental dissatisfaction with his care. His mother shared that she has tried many strategies to encourage Sam to eat including pushing spoons of food into his mouth, syringe feeding, and verbally pleading with Sam to take a bite, but all of these have been without success.Because of concerns that persistent attempts to verbally and physically coerce Sam to eat may be contributing to his aversion to food/eating, the feeding team provided Sam's parents with education and coaching for utilization of behavioral cues to determine when Sam wanted to eat. Despite parents expressing their understanding of the importance of avoiding physical attempts to "make" Sam eat and the team palliative care physician meeting with Sam's parents to elicit their goals for Sam's care, his nurses reported observing several instances of Sam's mother tapping a loaded spoon on his lips. Because of minimal oral intake, a nasogastric tube was placed for provision of hydration and nutrition. Sam's parents consented to the use of soft restraints and the presence of a bedside patient care assistant because of Sam becoming agitated and pulling at the tube.After 10 days of hospitalization, Sam was taking about 50% of his goal intake by mouth. Unfortunately, Sam removed his NG tube, and his parents refused to allow the tube to be replaced. Sam's parents then discharged him against medical advice, stating that they believed he would recover better at home. What are important considerations in caring for patients like Sam in the hospital setting and beyond?

The COVID-19 global health crisis compelled behavior analysts to consider alternatives to face-to-face services to treat children with feeding disorders. Research suggests telehealth is one method behavior analysts could use to initiate or continue assessment of and treatment for feeding disorders. In the current paper, we conducted pilot studies in which we analyzed chart records of patients with Avoidant/Restrictive Food Intake Disorder; who graduated from an intensive, day-treatment program; and transitioned to an outpatient follow-up program. In Experiment 1, we analyzed the data of participants who received follow-up both in-clinic and via telehealth. In Experiment 2, we analyzed goal attainment for participants who received outpatient follow-up either in-clinic exclusively or via telehealth exclusively. Results of both studies showed that outcomes were equivalent along most dimensions for in-clinic and telehealth services. We provide recommendations for telehealth feeding services and discuss other considerations relevant to telehealth service delivery.

Change-resistant behavior, such as rigid and selective food consumption, is a core symptom of autism that can have significant negative consequences for the child (Flygare Wallén et al., 2018; Levy et al., 2019). In the current study, we used a matching-law-based intervention (Fisher et al., 2019) to treat the change-resistant feeding behavior of 7 young children with autism. The feeder gave the participant a choice between a change-resistant and an alternative food during free- and asymmetrical-choice conditions. Alternative-food consumption increased for 2 participants during asymmetrical choice when the feeder provided a preferred item for consuming the alternative food and no programmed consequence for consuming the change-resistant food. Alternative-food consumption increased for the other 5 participants after the feeder exposed at least 1 food to single choice in which the feeder guided the participant to put the bite of alternative food in his or her mouth if he or she did not do so within 8 s of presentation. Effects of the single-choice contingencies maintained during reversals and generalized to other alternative foods the feeder did not expose to single choice. These results are important because participants consumed alternative foods even when their change-resistant foods were present, which is similar to typical mealtime contexts in which children have choices among foods.

Applied behavior analysis has the most empirical support as intervention for pediatric feeding disorders, when a child does not eat or drink a sufficient quantity or variety of food to maintain proper nutrition. Interdisciplinary collaboration is crucial for diagnosis, referral, and management of pediatric feeding disorders because the etiology is complex and multifactorial. Thus, our aim is to provide information about how to recognize a feeding disorder, to delineate the environmental variables implicated in the etiology and maintenance of feeding disorders, and to provide recommendations for prevention and intervention for feeding disorders based on the applied-behavior analytic literature.

Little is known about the food preferences of children with a feeding disorder and medical diagnoses. Therefore, we conducted repeated paired-stimulus-preference assessments with foods to which we either exposed or did not expose 3 children with a feeding disorder and medical diagnoses during clinical treatment. Responding was relatively equivalent for exposure and nonexposure foods throughout the preference assessments, suggesting that preferences for foods did not change due to exposure during treatment.

Results of several recent translational studies have suggested that correlating contextual or discriminative stimuli with the delivery and withholding of reinforcement for the functional communication response (FCR) may mitigate resurgence of destructive behavior, but few, if any, have isolated the effects of those stimuli. In the present study, we first trained the FCR, brought it under stimulus control of a multiple schedule, and thinned its reinforcement schedule in one stimulus context. Next, we conducted resurgence evaluations (i.e., baseline, functional communication training [FCT], extinction challenge) in two novel contexts to test the effects of the discriminative stimuli on resurgence. We programmed one context to include the (a) SD during the FCT phase to signal the availability of reinforcement for the FCR and (b) SΔ during a subsequent extinction challenge to signal the unavailability of reinforcement for the FCR. The other context did not include the SD during the FCT phase, nor the SΔ during the extinction challenge. We expected to see greater persistence of the FCR in the context that included the SD during FCT and less persistence of the FCR and less resurgence of destructive behavior in the context that included the SΔ during the extinction challenge. Obtained results confirmed this latter prediction, but we observed no reliable difference when the SD was present or absent during the FCT phase. Our results have relevance for practitioners in that they provide further empirical support for the use of discriminative stimuli when treating destructive behavior.

Parents play an important role in the treatment of their children's symptoms of autism spectrum disorder (ASD); thus, developing effective, efficient, socially acceptable, and accessible procedures for training parents to implement applied-behavior-analysis (ABA) interventions is critically important. One potential approach involves delivering training via a virtual private network (VPN) over the internet (Fisher et al., 2014). In this study, we conducted a randomized clinical trial to evaluate a virtual parent-training program with e-learning modules and scripted role-play via a VPN. We evaluated parent implementation of ABA skills using direct-observation measures in structured-work and play-based training contexts. Parents in the treatment group showed large, statistically significant improvements on all dependent measures; those in the waitlist-control group did not. Parents rated the training as highly socially acceptable. Results add to the growing literature on the efficacy and acceptability of virtually delivered training in ABA.

The term renewal describes the recurrence of previously extinguished behavior that occurs when the intervention context changes. Renewal has important clinical relevance as a paradigm for studying treatment relapse because context changes are necessary for generalization and maintenance of most intervention outcomes. The effects of context changes are particularly important during intervention for pediatric feeding disorders because children eat in a variety of contexts, and extinction is an empirically supported and often necessary intervention. Therefore, we used an ABA arrangement to test for renewal during intervention with 3 children diagnosed with a feeding disorder. The A phase was functional reinforcement of inappropriate mealtime behavior in a simulated home setting with the child's caregiver as feeder, B was function-based extinction in a standard clinic setting with a therapist as feeder, and the return to the A phase was function-based extinction in a simulated home setting with caregiver as feeder. Returning to Context A resulted in renewal of inappropriate mealtime behavior across children, despite the caregivers' continued implementation of function-based extinction with high levels of integrity.

Children with feeding disorders may pack food when they lack the oral-motor skills, the motivation, or both to swallow. Presenting bites on the tongue with a Nuk brush, or redistribution, replacing packed food on the tongue, are two treatments whose relative efficacy is untested. In the current study, we compared the effects of (a) presenting on an upright spoon, (b) presenting on a Nuk, and (c) redistributing with a Nuk on two product measures of swallowing, which we refer to as 15-s and 30-s mouth clean, for three children with feeding disorders. Nuk presentation produced the highest levels of 15-s mouth clean relative to Nuk redistribution and upright-spoon presentation across participants. Levels of 30-s mouth clean were higher during Nuk presentation and Nuk redistribution relative to upright-spoon presentation for two participants. We discuss the oral-motor skills and motivational deficits that might account for the findings.

Food selectivity is a common problem for children with autism spectrum disorder (ASD; Schreck, Williams, & Smith, 2004). Behavior-analytic interventions have the most empirical support for feeding disorders (Sharp, Jaquess, Morton, & Miles, 2011). However, there are no randomized controlled trials that have evaluated its effects with a well-defined cohort of children with ASD. In the current investigation, we randomly assigned 6 young children with ASD and food selectivity to either an applied behavior analytic intervention or a wait-list control. We used a crossover randomized controlled trial to evaluate the effects of a multicomponent applied behavior analytic intervention on independent acceptance and mouth clean of 16 novel foods. We subsequently exposed the wait-list control group to the intervention. We also evaluated the effects of the intervention on individual participants with single-case designs. The percentage of independent acceptance and mouth clean increased for the applied behavior analytic intervention group, but not for the wait-list control group until we implemented the intervention.

Children diagnosed with autism or autism spectrum disorders (ASD) are more likely than other children to exhibit behaviors characteristic of a feeding or sleeping disorder. Parents of children with these disorders may be extremely concerned about the health and safety of their child. Sleeping and feeding problems can cause a great deal of stress to parents and other family members. Behavioral assessment and treatment procedures have been developed to address behavior problems related to sleeping and feeding disorders. This article reviews the literature about assessment and treatment, and provides recommendations regarding services to family members of individuals diagnosed with ASD and feeding or sleeping disorders.

In the current investigation, we compared and evaluated the effects of two intervention procedures, a modified chin prompt and reclined seating, on the liquid expulsion of 2 children with feeding disorders. For both participants, expulsion decreased to clinically meaningful levels when we added the modified chin prompt or reclined seating to a treatment package consisting of differential reinforcement of acceptance, nonremoval of the cup, and re-presentation. We discuss possible mechanisms underlying the effects of the 2 interventions and areas for future research.

We evaluated the effects of escape extinction with and without a high-probability (high-p) instructional sequence on food acceptance and inappropriate behavior for children diagnosed with feeding problems. The high-p sequence consisted of three presentations of a response that was similar topographically (i.e., presentations of an empty nuk, liquid on a spoon, and a preferred liquid on a spoon) to the low-p response (i.e., presentation of a nuk with food, liquid from a cup, and presentation of a nonpreferred food). Acceptance of food increased in the presence and not the absence of the high-p sequence during initial withdrawals for two of the three children. In addition, the high-p sequence plus escape extinction was associated with reduced levels of inappropriate behavior relative to escape extinction alone for two children. Data are discussed in relation to behavioral momentum, motivating operations, and the relative contributions of the high-p instructional sequence and escape extinction in the treatment of feeding problems.

RESUMEN
Treatments of pediatric feeding disorders based on applied behavior analysis (ABA) have the most empirical support in the research literature (Volkert & Piazza, 2012); however, professionals often recommend, and caregivers often use, treatments that have limited empirical support. In the current investigation, we compared a modified sequential oral sensory approach (M-SOS; Benson, Parke, Gannon, & Muñoz, 2013) to an ABA approach for the treatment of the food selectivity of 6 children with autism. We randomly assigned 3 children to ABA and 3 children to M-SOS and compared the effects of treatment in a multiple baseline design across novel, healthy target foods. We used a multielement design to assess treatment generalization. Consumption of target foods increased for children who received ABA, but not for children who received M-SOS. We subsequently implemented ABA with the children for whom M-SOS was not effective and observed a potential treatment generalization effect during ABA when M-SOS preceded ABA.
