Doctoral psychology internships play a key role in the development of the competencies of the clinical child and adolescent psychologist workforce needed to serve the increasing behavioral and mental health needs of children. This study surveyed 50 internship training directors regarding workforce needs, the structure of experiential internship components, and the organizational infrastructure and funding of internship programs that provide focused care to children and adolescents within medical settings. Findings suggest that internships most commonly occur within academic medical settings and include clinical child psychology, integrated care, pediatric psychology, neuropsychology, and developmental disabilities tracks.

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.

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.

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.

To establish a foundation for methodologically sound research on the epidemiology, assessment, and treatment of pediatric feeding disorder (PFD), a 28-member multidisciplinary panel with equal representation from medicine, nutrition, feeding skill, and psychology from seven national feeding programs convened to develop a case report form (CRF). This process relied upon recent advances in defining PFD, a review of the extant literature, expert consensus regarding best practices, and review of current patient characterization templates at participating institutions. The resultant PFD CRF involves patient characterization in four domains (ie, medical, nutrition, feeding skill, and psychosocial) and identifies the primary features of a feeding disorder based on PFD diagnostic criteria.

Objective: Expert consensus increasingly recognizes intensive multidisciplinary intervention (IMI) as the standard of care to address chronic and severe feeding problems in pediatric populations. In this study, we examined the clinical presentation, intervention characteristics, and treatment outcomes for young children receiving IMI for avoidant restrictive rood intake disorder (ARFID) involving nutritional insufficiencies associated with severe food selectivity.

Method: We followed the Strengthening the Reporting of Observational Studies in Epidemiology statement to conduct this retrospective chart review.

Objective: Evidence suggests intensive multidisciplinary intervention holds benefit for children with feeding tube dependence complicated by comorbid medical, behavioral, and/or developmental conditions; however, much remains unknown regarding factors affecting a patient achieving full oral feeding after intervention.

Methods: This retrospective review involved consecutive patients (birth to age 21 years) admitted to an intensive multidisciplinary intervention program over a 5-year period (June 2014-2019) for feeding tube dependence and food refusal. This study compared the clinical presentation and treatment outcomes for patients who successfully transitioned to full oral feeding versus patients experiencing a partial wean at the last follow-up.

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.

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.

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.

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.

Operant renewal is a return of extinguished behavior due to changes in contextual stimuli that control the occurrence or nonoccurrence of a response. Well-established in classical conditioning and operant research, renewal presents itself in three forms-ABA, ABC, and AAB-and poses threats to treatment maintenance where extinction procedures are utilized. As AAB renewal may be less likely to occur than ABA or ABC renewal, the current study sought to determine if AAB renewal would occur with three participants with Autism Spectrum Disorder who were taught a simple lever pull response.

Although some children with feeding disorders may have the necessary skills to feed themselves, they may lack motivation to self-feed solids and liquids. Rivas, Piazza, Roane, Volkert, Stewart, Kadey, and Groff (Journal of Applied Behavior Analysis, 47, 1-14, 2014) and Vaz, Volkert, and Piazza (Journal of Applied Behavior Analysis, 44, 915-920, 2011) successfully increased self-feeding for children who lacked motivation to self-feed by manipulating either the quantity or the quantity and quality of bites that the therapist fed the child if he or she did not self-feed. In the current investigation, we present three case examples to illustrate some challenges we faced when using these procedures outlined in the aforementioned studies and how we addressed these challenges.

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.

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.
