Evaluating a Treatment Package for Avoidant/Restrictive Food Intake Disorder to Increase Food Variety.

There is a dearth of published research evaluating behavior-analytic assessment and treatment of avoidant/restrictive food intake disorder (ARFID) given the recent revisions in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. In this study, therapists conducted periodic food preference assessments to help guide treatment for a typically developing child with ARFID and food selectivity. Further, therapists evaluated a treatment package including demand fading, escape prevention, and self-monitoring to increase food variety. Consumption increased during treatment with target foods; however, preference shifts were minor when compared to the pretreatment food preference assessment. Variety continued to increase overtime using the same treatment package and treatment effects were generalized to family meals and other locations.

Looking Beyond the Growth Curve: A Retrospective Study on Nutrient Deficient Diets in Children with Severe Food Selectivity.

Severe food selectivity places children at risk for nutrient deficiencies and long-term medical complications, if unaddressed. However, poor nutrition in highly selective eaters is often overlooked when considering other behavioral or medical concerns. Additionally, studies regarding food selectivity are sparse and limited to children with developmental delays. This study further investigates the nutritional deficiencies and growth characteristics of children with severe food selectivity to assist pediatricians in the earlier identification of patients for nutrition screening. A retrospective chart review was completed for 13 patients admitted to a pediatric feeding program solely for table-textured food selectivity. Nutrition and anthropometric data from the medical record were analyzed. All patients were determined to be following an age-appropriate growth curve but had multiple micronutrient deficiencies. Additionally, 6 children were typically developing outside of the feeding context. Results suggest that children with food selectivity may require more intensive and earlier nutrition screening beyond their growth patterns.

Using an intensive interdisciplinary telehealth model to treat pediatric feeding disorders.

The necessity of treatment using telehealth was apparent during the novel coronavirus (COVID-19) pandemic, as many practitioners were forced to use telehealth as a primary mode of service delivery. Although the telehealth model has been studied for different populations, little is known about its success when applied with children with feeding disorders and complex medical histories. The purpose of this study was to evaluate the efficacy of using a telehealth model from the onset of treatment. All 5 children who participated engaged in low levels of acceptance and high levels of inappropriate mealtime behavior during baseline. Caregivers were taught to implement the treatment with high integrity using behavioral skills training. Procedural integrity increased posttraining, and as a result acceptance increased and inappropriate mealtime behavior decreased. Treatment gains maintained during follow up at 1 month and 1 year. These data are discussed in relation to alternative ways of providing treatment in locations where intensive feeding programs are not available.

Evaluating Outcome Measure Data for an Intensive Interdisciplinary Home-Based Pediatric Feeding Disorders Program.

BACKGROUND: The purpose of this study was to evaluate the effectiveness of an interdisciplinary home-based feeding program, which is a unique service delivery model. METHODS: Data were provided on oral intake, tube feeding elimination, and weight for patients who were dependent on tube feedings (n = 78). Weight data were collected for patients who showed failure to thrive (n = 49). Number of foods consumed and percentage of solids were collected for patients who were liquid-dependent (n = 23), and number of foods consumed were collected for patients who were food-selective (n = 61). RESULTS: Data were analyzed using paired sample t-test with 95% confidence interval. For patients dependent on tube feedings, 81% achieved tube feeding elimination. Tube elimination was achieved after 8 months of treatment on average. All failure-to-thrive patients showed weight gain from baseline to discharge. For liquid-dependent patients, there was an increase in foods consumed from 2 foods at admission to 32 foods at discharge. For food selective patients, there was an increase from 4 foods at admission to 35 foods at discharge. For all dependent variables, results showed statistical significance and a large-sized effect. CONCLUSIONS: These data show that an intensive interdisciplinary home-based program can be successful in treating complex feeding problems in children.

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.

An evaluation of trial-based functional analyses of inappropriate mealtime behavior.

Functional analyses allow clinicians to develop treatment targeting the variables maintaining a child's inappropriate mealtime behavior (Bachmeyer et al., 2019). Extended functional analyses can be inefficient, potentially delaying the onset of treatment. Researchers have suggested a trial-based functional analysis can increase assessment efficiency (Saini, Fisher, et al., 2019). This study compared trial-based functional analyses to extended functional analyses to determine the variables maintaining inappropriate mealtime behavior. We compared the efficiency and acceptability and evaluated treatments informed by the analyses. Exact correspondence between analyses was low (29%); however, most treatments indicated by the trial-based functional analyses (80%) resulted in improvements in the child's target behavior. The trial-based functional analysis required 71% less time than the extended functional analysis, and caregivers found analyses equally acceptable. Future researchers should continue refining trial-based functional analysis procedures to provide an efficient assessment that leads to efficacious treatment.

A Demonstration of Caregiver-Implemented Functional Analysis of Inappropriate Mealtime Behavior via Telehealth.

Treatment for pediatric feeding disorders is imperative, so clinicians should alter the assessment and treatment process, making it is possible for caregivers to deliver via telehealth. Clinicians must first demonstrate that caregivers can conduct initial assessments in this format. We extended the literature on functional analysis of inappropriate mealtime behavior by demonstrating that caregivers can implement functional analysis procedures via telehealth to identify maintaining variables of inappropriate mealtime behavior. Clinicians determined that escape, attention, and tangibles and escape maintained inappropriate mealtime behavior during solids and liquids meals, respectively.

Pediatric Prevention: Feeding Disorders.

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.
