Parent training for feeding problems in children with autism spectrum disorder: A review of the literature

"Still work?" Design and effect of interventions used to modify feeding problems in children with autism: A systematic review of studies employing group designs

BACKGROUND

Feeding problems in children with autism jeopardize the well-being of both children with autism and their families. Mixed findings were reported from previous interventions, which were mostly evaluated by single subject research design (SSRD) studies. Moreover, feasibility assessment and social validity measurement were unaddressed by these SSRD studies. To fill this substantial knowledge gap, the present review systematically summarized and evaluated feeding interventions implemented in children with autism, which were assessed by studies employing group designs.

METHOD

An extensive literature search in eight established online databases was conducted, and a total of 17 eligible studies published in 2009-2021 were included for further analysis. A descriptive account of the features of the investigations is provided, including assessment of study quality.

RESULTS

A total of 449 children with autism and 203 parents/caregivers participated in the included studies. The multiple use of five strategic intervention components were highlighted in this review, including nutrition education/consultations, environmental modifications, sensory exposure, cognitive components, and behaviour interventions. The reviewed interventions showed a preliminarily positive effect for modifying feeding problems in children with autism. Furthermore, the evaluation based on the RE-AIM framework (reach, efficacy, adoption, implementation, and maintenance) demonstrated that an interdisciplinary multi-component intervention strategy may achieve high effectiveness and feasibility in improving feeding problems in a wide range of children with autism.

CONCLUSIONS

This review found that interventions achieved and maintained a positive effect on modification of feeding problems in groups of children with autism. Information and gaps identified and summarized in the implementation process may assist both researchers and stakeholders to further support these vulnerable children.

"Giving Me the Self-Confidence to Tackle It": Mothers' Experiences Participating In The Engaged Eaters Program, A Caregiver-Mediated Feeding Intervention

The purpose of this study was to understand caregivers' experience of participating in a caregiver-mediated in-home feeding intervention, the Engaged Eaters Program, for their young autistic child. This qualitative study utilized a thematic approach to analyze post-intervention semi-structured interviews with thirteen mothers of autistic children between the ages of 2 to 7 years after they participated in the intervention. Interview questions focused on the child and family experience, what worked well, what could be improved, and how the intervention integrated into family routines. Four major themes were identified: In-Home Intervention, Parent Skill and Knowledge, Increased Social Participation, and Parent Responsibilities and Challenges. Sub-themes provided descriptions of learning practical tools to support their child, increasing self-efficacy, and impacts on family life. Mothers described an increase in tangible skills that were easily practiced in the home environment that improved their confidence and self-efficacy in feeding their children. They also described how participation did require more work and time commitment for them beyond their regular responsibilities. The caregiver experience is essential to understand for intervention effectiveness while simultaneously addressing child, caregiver, and family needs. By focusing on the mothers' experiences, individualized needs, and self-efficacy, we were able to better understand how integrating an intervention into the family context and daily routines may be beneficial for the whole family.

Examining adaptations necessary to support the implementation of a parent-mediated intervention for children with autism spectrum disorder and moderate feeding problems

LAY ABSTRACT

Moderate feeding problems and disruptive mealtime behaviors are common in children with autism spectrum disorder. Although parent-mediated interventions are able to support feeding problems in autistic children, most research has occurred within specialty clinics when delivered by highly trained clinicians. Thus, the fit of these interventions within community settings is not clear. To address this limitation, this study explored adaptations to a parent-mediated intervention, Managing Eating Aversions and Limited Variety (i.e. MEAL Plan), to improve its fit and use within community settings. Participants were 14 multidisciplinary providers who attended one of the three intensive workgroups that included focus groups about the fit of MEAL Plan in their practice setting. Qualitative analysis was used to determine the main themes that came up within the focus groups. Specific themes included the appropriateness MEAL Plan for autistic and non-autistic children, how providers might adapt their delivery of MEAL Plan, billing and insurance considerations, administrator support for MEAL Plan, and the content and format of ongoing training and consultation. By proactively considering and responding to these factors, it may be possible to enhance MEAL Plan so that it is better able to be delivered and sustained within community practices that support autistic children.

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.

Parental Feeding Concerns for Children With Autism Spectrum Disorder: A Family-Centered Analysis

This study identifies and describes feeding concerns of parents of children with autism spectrum disorder (ASD) and examines the extent to which parents relate those concerns as having been addressed by therapists. Survey data were collected from 113 parents of children with ASD. Of the parents surveyed, 68% described a past or present concern with feeding; 60% of those parents with concerns said a therapist had not addressed those concerns. Feeding concerns were more likely addressed when therapists shared parent's concerns. Specific types of concerns, such as those around food selectivity and food refusal, were more likely addressed than difficulties around mealtime. A gap is identified between parental report of feeding difficulties and parental report of professional services addressing feeding needs. This analysis presents an opportunity for occupational therapists in the area of feeding, particularly around identifying and addressing parental concerns.
