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.

Avaliação e intervenção responsiva e integrativa na criança com distúrbio alimentar pediátrico com Trissomia do 21: Relato de caso / Responsive and integrative assessment and intervention in children with pediatric feeding disorder with Trisomy 21: A case report / Evaluación e intervención receptiva e integradora en un niño con trastorno alimentario pediátrico con Trisomía 21: Reporte de caso

Na criança com Trissomia do 21 a dificuldade alimentar pode estar presente. Alguns sinais são as alterações na habilidade motora-oral, no processamento sensorial, tempo elevado das refeições, recusa alimentar prolongada e falta de autonomia. Ainda pouco se discute sobre as dificuldades alimentares e seu processo terapêutico nesta população. O objetivo deste estudo foi descrever a avaliação e intervenção fonoaudiológica e da terapia ocupacional na dificuldade alimentar de uma criança com Trissomia do 21 com o uso de estratégias de alimentação responsiva e integrativa. Criança 3 anos e 2 meses, sexo masculino. Avaliação fonoaudiológica demonstrou criança com distúrbio alimentar pediátrico, caracterizado por atraso na habilidade motora-oral, baixa percepção intraoral e comportamento alimentar altamente seletivo. Na avaliação da terapia ocupacional verificou-se perfil sensorial alterado. Na fonoterapia foram trabalhados aspectos como a percepção do alimento, ritmo e o tempo de alimentação. Na terapia ocupacional, o objetivo foi adequar nível de alerta, favorecer a independência e o desenvolvimento psicomotor. Após a intervenção, a reavaliação fonoaudiológica demonstrou que houve ampliação do cardápio, melhora da percepção, da habilidade motora intraoral, aceitação de diferentes utensílios e modos de apresentação do alimento, autonomia e prazer nas refeições. A reavaliação da terapia ocupacional mostrou um nível de alerta e atenção mais adequado, uso das mãos e dedos de maneira mais funcional para se alimentar. Foram observadas evoluções positivas em relação à intervenção fonoaudiológica e da terapia ocupacional na dificuldade alimentar de uma criança com Trissomia do 21 com o uso de estratégias de alimentação responsiva e integrativa.

In children with Trisomy 21 feeding difficulty can be observed, such as changes in oral motor skills, sensory processing, longer mealtimes, food refusal, lack of autonomy and others. However, there is little discussion about feeding difficulties and rehabilitation process in this population. This study aimed to describe speech-language and occupational therapy assessment and intervention in feeding difficulties in a 3-year and 2-month-old male child with a diagnosis of Trisomy 21. Speech-language pathology assessment found that the child had feeding difficulties, delay in oral motor skills, low intraoral perception and acceptance, while the occupational therapy assessment showed an altered sensory profile. The speech-language pathology sessions included aspects such as food perception, rhythm and feeding time. In turn, occupational therapy sessions aimed to adjust the alertness level, promote independence and psychomotor development. After the intervention, the speech-language pathology reassessment showed that there was an expansion of the menu for the ingestion, improvement in perception and intraoral motor skills, acceptance of different utensils and food presentation modes, autonomy and pleasure in meals. The reassessment of occupational therapy showed a better level of alertness and attention, more functional use of hands and fingers to eat. Therefore, a positive progress was observed in the feeding difficulty of a child with Trisomy 21 after a speech-language pathology and occupational therapy intervention with the use of responsive and integrative feeding strategies.

On the role of operant contingencies in the maintenance of inappropriate mealtime behavior: An epidemiological analysis.

Functional analysis is the primary assessment used to determine the function of inappropriate mealtime behavior in children with feeding disorders. Based on single-case experimental design studies and recent reviews, the prevalence of negative reinforcement alone in the maintenance of inappropriate mealtime behavior appears to be much greater than positive reinforcement alone. We conducted a retrospective consecutive-controlled case series to determine the generality of previous findings. Results of the epidemiological analysis support prior research in that negative reinforcement in the form of escape (44.8%), and multiple control (i.e., positive and negative reinforcement) in the forms of escape and attention (37.2%), are considerably more prevalent than positive reinforcement alone (2.5%). We discuss the relationship between functional analysis of inappropriate mealtime behavior and treatment utility. Further, we describe avenues of future research designed to advance the application of functional analysis in feeding disorders beyond inappropriate mealtime behavior.

A comparison of function- and nonfunction-based extinction treatments for 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.

CROSS-CULTURAL ADAPTATION AND VALIDATION OF THE MONTREAL CHILDREN'S HOSPITAL FEEDING SCALE INTO BRAZILIAN PORTUGUESE.

OBJECTIVE: To cross-culturally adapt and validate the Montreal Children's Hospital Feeding Scale (MCH-FS) into Brazilian Portuguese. METHODS: The MCH-FS, originally validated in Canada, was validated in Brazil as Escala Brasileira de Alimentação Infantil (EBAI) and developed according to the following steps: translation, production of the Brazilian Portuguese version, testing of the original and the Brazilian Portuguese versions, back-translation, analysis by experts and by the developer of the original questionnaire, and application of the final version. The EBAI was applied to 242 parents/caregivers responsible for feeding children from 6 months to 6 years and 11 months of age between February and May 2018, with 174 subjects in the control group and 68 ones in the case group. The psychometric properties evaluated were validity and reliability. RESULTS: In the case group, 79% of children were reported to have feeding difficulties, against 13% in the control group. The EBAI had good internal consistency (Cronbach's alpha=0.79). Using the suggested cutoff point of 45, the raw score discriminated between cases and controls with a sensitivity of 79.4% and specificity of 86.8% (area under the ROC curve=0.87). CONCLUSIONS: The results obtained in the validation process of the EBAI demonstrate that the questionnaire has adequate psychometric properties and, thus, can be used to identify feeding difficulties in Brazilian children from 6 months to 6 years and 11 months of age.

Assessment of clinical practice procedures among Registered Dietitian Nutritionists for identifying feeding dysfunction in the pediatric population.

BACKGROUND & AIMS: Feeding dysfunction is common in children. Efficient processes to identify and treat feeding dysfunction are not commonly known or used among healthcare practitioners. The aim of this study was to develop and validate a survey tool to assess current practice procedures used by Registered Dietitian Nutritionists (RDN) in identifying, diagnosing, and treating feeding dysfunction in children 0-18 years of age. METHODS: A survey was developed and distributed to gather information on RDN practice procedures, prevalence of pediatric feeding dysfunction, identification of pediatric feeding dysfunction, and method of treatment used to address pediatric feeding dysfunction. Emails were sent to 4449 RDNs in United States. All participants were classified by the Commission on Dietetic Registration (CDR) as clinical dietitians. Distribution and frequency of survey responses were assessed, and in the case of qualitative questions, were categorized according to themes identified. RESULTS: Responses of RDNs from 41 states completed 341 total surveys, 179 surveys were included in data analysis. Eighty percent of participants do not use a specific screening tool to identify feeding dysfunction. Results concerning feeding therapy strategies and terms used by RDNs to describe feeding dysfunction were highly varied or lacking. Increased inclusion of RDNs on interdisciplinary teams was indicated by 80% of participants. The majority of participants indicated they refer patients with feeding dysfunction to other practitioners instead of providing feeding therapy themselves. CONCLUSIONS: Standardized screening, diagnostic, and treatment protocols regarding feeding dysfunction are needed to provide consistent and comprehensive care for the pediatric population. Use of these protocols among RDNs would enable them to improve feeding abilities in more patients earlier in individual child development.

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.

Further examination of the treatment of multiply controlled inappropriate mealtime behavior.

We systematically replicated Bachmeyer et al. (2009) by examining extinction procedures matched to each function, individually and in combination, to treat the food or liquid refusal of 4 children diagnosed with a feeding disorder whose inappropriate mealtime behavior was maintained by multiple functions (i.e., escape and attention). Previous research suggests that adding differential reinforcement to extinction procedures may result in better treatment outcomes. Therefore, we added differential reinforcement to extinction procedures matched to each function. Differential reinforcement and extinction matched only to escape or attention resulted in low rates of inappropriate mealtime behavior and high, stable levels of acceptance for only 1 child. Consistent with Bachmeyer et al., inappropriate mealtime behavior decreased, and acceptance increased for the remaining 3 children only after we matched differential reinforcement and extinction procedures to both escape and attention.

Further evaluation of modified-bolus-placement methods during initial treatment of pediatric feeding disorders.

Children with feeding disorders might pack or expel food when they lack the oral-motor skills, the motivation, or both, to swallow. Bolus placement directly on the tongue with a Nuk (e.g., Milnes et al., 2019) or flipped spoon (e.g., Sharp et al., 2010) is a treatment that researchers generally implement after such behavior emerges (e.g., Girolami et al., 2007). However, Wilkins et al. (2014) tested the relative efficacy of Nuk presentation and upright-spoon presentation during initial treatment of pediatric feeding disorders. In the current study, we compared the effects of (a) upright-spoon presentation; (b) Nuk presentation; and (c) flipped-spoon presentation on two product measures of swallowing: 15- and 30-s mouth clean, and expulsion during the initial treatment of feeding disorders with 5 children. We also monitored lip closure during bite presentation and following bolus placement. Nuk presentation produced the highest levels of mouth clean and the lowest rates of expels relative to upright-spoon presentation and flipped-spoon presentation. We discuss potential reasons why modified-bolus-placement methods improved feeding behavior and how measures of oral-motor skills might predict its necessity during initial treatment.

Intensive Multidisciplinary Intervention for Young Children with Feeding Tube Dependence and Chronic Food Refusal: An Electronic Health Record Review.

OBJECTIVE: To assess characteristics and outcomes of young children receiving intensive multidisciplinary intervention for chronic food refusal and feeding tube dependence. STUDY DESIGN: We conducted a retrospective study of consecutive patients (birth to age 21 years) admitted to an intensive multidisciplinary intervention program over a 5-year period (June 2014-June 2019). Inclusion criteria required dependence on enteral feeding, inadequate oral intake, and medical stability to permit tube weaning. Treatment combined behavioral intervention and parent training with nutrition therapy, oral-motor therapy, and medical oversight. Data extraction followed a systematic protocol; outcomes included anthropometric measures, changes in oral intake, and percentage of patients fully weaned from tube feeding. RESULTS: Of 229 patients admitted during the 5-year period, 83 met the entry criteria; 81 completed intervention (98%) and provided outcome data (46 males, 35 females; age range, 10-230 months). All patients had complex medical, behavioral, and/or developmental histories with longstanding feeding problems (median duration, 33 months). At discharge, oral intake improved by 70.5%, and 27 patients (33%) completely weaned from tube feeding. Weight gain (mean, 0.39 ± 1 kg) was observed. Treatment gains continued following discharge, with 58 patients (72%) weaned from tube feeding at follow-up. CONCLUSIONS: Our findings support the effectiveness of our intensive multidisciplinary intervention model in promoting oral intake and reducing dependence on tube feeding in young children with chronic food refusal. Further research on the generalizability of this intensive multidisciplinary intervention approach to other specialized treatment settings and/or feeding/eating disorder subtypes is warranted.

Parental management of feeding problems in young children-a population-based study.

OBJECTIVES: To investigate the practices that parents use to manage feeding problems in healthy children and in children with gastrointestinal diseases. Secondly, for each of these two groups we examined the association of select child and parent variables with parental feeding practices. METHODS: This is a cross-sectional case-control study. The sample consisted of 901 children (765 healthy children of typical development and 136 children with gastrointestinal diseases), aged one to seven years. The feeding problem management practices were investigated through 23 closed-ended questions. The anthropometric and demographic data of children and the demographic data of parents were collected by administering structured set of questions to parents. RESULTS: The prevalence of parent-reported feeding problems was 30.6% for healthy children and 45.7% for children with gastrointestinal diseases. The most common practices adopted by parents of healthy children were highlighting the benefits of food (80.5%), correlating food with pleasure (71.6%) and praising (59.1%), whereas almost half of the parents were found not to accept that their children may not be hungry and insisted on trying to feed them. Statistically significant differences were noted in many parental practices between the two groups. Parents of children with gastrointestinal diseases were generally more involved in the feeding process. Verbal praising (69.1%), correlation with pleasure (79.4%), promotion of benefits (77.2%) as well as assistance during feeding (63.2%) were the most common parental practices in the gastrointestinal group. Age, birth order, being the only child and weight status were child variables that differentiated parental behavior. Parental characteristics that affected feeding practises were age, education and work status. CONCLUSIONS: A high prevalence of feeding problems was reported by parents of both healthy children and children with gastrointestinal diseases. Beside the presence of a disease, specific child and parent variables are significantly related to parental behavior when managing feeding problems.

Evaluation of a finger prompt variation in the treatment of pediatric feeding disorders.

Children with feeding disorders often engage in refusal behavior to escape or avoid eating. Escape extinction combined with reinforcement is a well-established intervention to treat food refusal. Physical guidance procedures (e.g., jaw prompt, finger prompt) have been shown to increase food acceptance and decrease inappropriate mealtime behavior when more commonly employed escape extinction (e.g., nonremoval of the spoon) procedures are ineffective. The finger prompt, however, has not been extensively evaluated as a treatment adjunct to target food refusal, thus necessitating further examination. The purpose of this prospective study was to assess a variation of a finger prompt procedure to treat food refusal and to assess caregivers' acceptability of the procedure. Three children age 1 to 4 years admitted to an intensive feeding disorders program and their caregivers participated. The finger prompt was effective in increasing bite acceptance across all participants and decreasing or maintaining low levels of inappropriate behavior for 2 participants. The procedure was also acceptable to all caregivers.

Feeding difficulties in children with autism spectrum disorder: Aetiology, health impacts and psychotherapeutic interventions.

Feeding difficulties are common and significant issues for children with autism spectrum disorder and their families. Key features of autism are intrinsically linked with factors contributing to these children's feeding difficulties. Following a multidisciplinary assessment to exclude non-behavioural reasons for the feeding difficulty, there are two mainstay modalities of treatment: operant conditioning and systematic desensitisation. Currently, evidence points towards operant conditioning as the most efficacious psychotherapy. However, recent research into cognitive behavioural therapy for older children with feeding difficulties has shown promising results and will be an area to monitor in the coming years. This review outlines the causes and health impacts and evaluates current evidence supporting the available psychotherapeutic interventions for children with autism spectrum disorder experiencing feeding difficulties.

Randomized controlled trial of an applied behavior analytic intervention for food selectivity in children with autism spectrum disorder.

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.

A translational evaluation of renewal of inappropriate mealtime behavior.

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.

A systematic review of functional analysis in pediatric feeding disorders.

We conducted a systematic review of the functional analysis of inappropriate mealtime behavior in peer-reviewed studies in PsycINFO, ERIC, PubMed, and the Journal of Applied Behavior Analysis between 2000-2016. We identified 18 studies involving 86 functional analyses. We coded descriptive data and calculated summary statistics in addition to conducting a quality appraisal of the literature. We identified escape, exclusively or in part, as the maintaining reinforcer for inappropriate mealtime behavior in 92% of cases. Results indicate that differentiated functional analyses of inappropriate mealtime behavior can be obtained, and outcomes are consistent with etiological theories of food refusal behavior. We discuss procedural differences across studies as well as directions for future research.

Modified-Bolus Placement as a Therapeutic Tool in the Treatment of Pediatric Feeding Disorders: Analysis From a Retrospective Chart Review.

Purpose Recognizing the need to advance the treatment of pediatric feeding disorders, an emerging area of inquiry focuses on therapeutic techniques that address expulsion and packing possibly associated with oral-motor dysfunction. In the current study, we documented the use of modified-bolus placement in the treatment of pediatric feeding disorders at an intensive, multidisciplinary day-treatment center over a 26-month period. Method The retrospective observational cohort study involved patients admitted for the assessment and treatment of chronic food refusal from August 2013 to October 2015. Results Patients (n = 23) who received modified bolus placement displayed moderate-to-severe oral-motor deficits. Use of modified-bolus placement was associated with reduced expulsion and packing of bites during meals, and treatment gains coincided with a threefold increase in grams consumed per meal. Conclusion Results provide additional support for the potential therapeutic benefits of enhancing bolus placement onto the tongue as a means to improve mealtime performance in children with pediatric feeding disorders when included as an adjunct to more traditional behavioral approaches.

Noncontingent and differential reinforcement in the treatment of pediatric feeding problems.

We conducted functional analyses of the inappropriate mealtime behavior of 5 children diagnosed with feeding problems. Then, we compared the effects of differential and noncontingent reinforcement, and the relative effects of escape extinction with and without differential or noncontingent reinforcement, when escape extinction appeared necessary. Both reinforcement procedures were effective without escape extinction to treat food refusal for 1 child, but only differential reinforcement was effective without escape extinction to treat the child's liquid refusal. Escape extinction was necessary for 4 of 5 children. The addition of positive reinforcement resulted in beneficial effects (i.e., more stable acceptance, decreased inappropriate mealtime behavior or negative vocalizations) with 3 of 4 children. With escape extinction, differential reinforcement was more effective to treat food refusal for 2 children and noncontingent reinforcement was more effective for 1 child.

A comparison of functional analysis methods of inappropriate mealtime behavior.

Investigators have evaluated two procedural variations for conducting a functional analysis of inappropriate mealtime behavior exhibited by children with feeding problems. One method involves prompting bites only in the escape condition (e.g., Najdowski et al., 2008). Another method involves prompting bites across all conditions (e.g., Piazza et al., 2003). We assessed the food refusal of 3 children diagnosed with a feeding disorder by comparing the two variations. The two methods resulted in different outcomes for 2 of 3 children. Prompting bites only in the escape condition identified a single function (i.e., escape). Prompting bites across all conditions identified multiple functions (i.e., escape and attention). We then examined the relative effects of extinction procedures (individually and in combination) to determine the validity of each method. Results of the treatment evaluation suggested that the procedural variation that failed to identify an attention function for 2 of 3 children produced false negative findings.
