The Role of Mealtimes in Fostering Language Development and Aligning Home and School Learning: Protocol for a Multi-Method Study of Preschool Children in Rural Kenya and Zambia.

BackgroundThe association between school and home is fundamental to sustainable education: parents’ understanding of the school’s priorities and teachers’ understanding of their pupils’ home environment are both vital for children to remain in school and succeed academically. The relationship between parents and teachers is closest in preschool settings, providing a valuable opportunity to build bridges between home and school. In this protocol paper, we outline our planned methods for identifying beneficial home and school behaviors.ObjectiveOur project aims to identify culture-specific structures and behaviors in home and school settings, which influence the quantity and quality of child-directed speech and identify positive experiences that can help improve children’s linguistic development and nutrition.MethodsUsing a mixed methods approach and focusing on early language learning, nutrition, and responsive caregiving, we will video-record and analyze mealtime language and eating behaviors at home and in school, targeting 80 preschool children and their families in rural Kenya and Zambia. In addition, we will assess children’s language skills through audio recordings and use questionnaire-based interviews to collect extensive sociodemographic and dietary data.ResultsBetween the start of our project in January 2020 and the end of December 2021, we had collected complete sets of sociodemographic, observational, and food recall data for 40 children in Kenya and 16 children in Zambia. By the end of May 2022, we had started data collection for an additional 24 children in Zambia and transcribed and coded approximately 85% of the data. By the end of September, 2022, we plan to complete data collection, transcription, and coding for the entire sample of 80 children across both countries. From September 2022 onwards, we will focus on analyzing our language data, and we hope to have results ready for publication in early 2023. By relating children’s language outcomes and nutritional intake to the observed mealtime behaviors, we hope to identify practices that increase the quantity and quality of child-directed speech and improve children’s nutritional intake.ConclusionsGood nutrition and the promotion of language learning are key issues in early childhood development. By using a cross-cultural approach, combining a variety of methods, and working closely with stakeholders and policy makers throughout the project, we hope to find and share best practices for improving children’s linguistic outcomes and nutrition and lay the foundation for the development of practitioner networks and parent outreach programs.International Registered Report Identifier (IRRID)DERR1-10.2196/36925

Eating and sleep problems, related factors, and effects on the mental health of the parents in children with autism spectrum disorder

This study aimed to evaluate the frequency of sleep and eating problems in children with autism spectrum disorder (ASD), the factors associated with these problems, and the relationship with the risk of developing depression and anxiety in their parents. In the study, 156 children with ASD and their parents were included. The Brief Autism Mealtime Behavior Inventory (BAMBI), the Children's Sleep Habits Questionnaire (CSHQ), the Hospital Anxiety Depression Scale (HADS) were completed by the parents. The Childhood Autism Rating Scale (CARS) was administered by the researchers to evaluate the severity of ASD in children. The mean age of children was 8.08 ± 2.84, and 87.2% of the children were male. The mean score of CARS was 41.25 ± 6.16, the mean score of BAMBI was 45.67 ± 11.87, and the mean score of CSHQ was 51.67 ± 10.17. According to the CSHQ, 83.3% of the children had sleep problems. The response rate above the cut-off point in the HAD-A subscale was 59.6%, whereas it was 67.3% in the HAD-D subscale. There was a positive correlation between CARS and BAMBI, CSHQ, HAD-A, and HAD-D subscales. There was a positive correlation between BAMBI and CHSQ, HAD-A, and HAD-D subscales. There was a positive correlation between the CSHQ, HAD-A, and HAD-D subscales. There was a negative correlation between the age of the child with ASD, food refusal, and resistance to bedtime. As sleeping and eating problems affect a large portion of children diagnosed with ASD and their caregivers, large population-based studies evaluating both these problems must be designed and carried out to understand factors affecting the prevalence, development, and persistence of sleeping and eating problems and to determine interventions to reduce these issues.

Food neophobia - natural developmental stage or feeding difficulty? A study of children's behavior and parents' knowledge about children’s neophobic behaviors

Background: An increasing number of parents report problems with feeding their children to dieticians. Failure to expand the diet or sudden discontinuation of a variety of foods makes them increasingly worried about their child's monotonous diet and mealtime behavior The aim of this study was to assess parents' awareness of food neophobia and the attitudes and behaviors associated with it.
 Material and method: The study was carried out using a questionnaire-based indirect survey technique using a web form (CAWI). A total of 224 adults (parents of preschool children) participated in the study. The research tool was an anonymous survey questionnaire consisting of three parts. In the last part, a scale concerning neophobic behavior was used. The study group consisted mainly of mothers - 78.3% (n=159); fathers - 21.7% (n= 44).
 Results: In the study group, no child scored several points indicating a very high probability of neophobia. A high probability is possible in 28 children (13.79%), a possible predisposition to the occurrence of food neophobia exists in 66 children (32.51%), while 109 children (53.69%) do not present a predisposition to food neophobia.
 Conclusions: The study did not show children's behaviors reported by parents that could indicate a very high probability of food neophobia in their children. Moreover, the results of the questionnaire of neophobia scale indicate that this problem in the studied population concerns about 10% of the examined children.

Review of Normative Scores on the Child Assessment of Functional Eating (C.A.F.E.)

Abstract Date Presented 04/02/2022 The Child Assessment of Function Eating (CAFE) was designed to provide a comprehensive feeding assessment, with all major components (self-feeding, self-drinking, mealtime behavior, oral-motor skills, sensory food preferences, nutritional intake) in one assessment. This poster will present the normative data obtained from 63 children ages 3-7 years who were evaluated with the CAFE. Data collection included a 3-day food diary, the CAFE form, and a food preference checklist.

Eating behaviors in children with Down syndrome: Results of a home-use test.

Children with Down syndrome (DS) display a disproportionate number of health challenges, including feeding and swallowing difficulties and food texture sensitivities. To start addressing food texture challenges early in life, the aim of this research was to understand mealtime behaviors and identify preferred food textures of children with DS. Children (aged 11 to 58 months) with DS (n= 111) and without (typically developing, TD; n= 107) participated in a home use test evaluating snack products of varying textures. Parents recorded their children's reactions to each food product; a panel of trained coders coded videos for mealtime behaviors. Children were also identified as food texture sensitive (TS) or non-texture sensitive (NTS). Results showed that age, TS, the presence of a DS diagnosis and the TS*DS interaction influenced the child's behaviors to the food products. Children with DS were more likely to increase distance from the food, mouth/suck on the food, and less likely to chew/much on the food compared to children TD. Children with DS also ate significantly less than typically developing children. Similar mealtime behaviors were observed between the children with TD/<30 months of age and children with DS regardless of age (p< .05). While children with DS/TS had a higher disposition for the dissolvable texture, along with products that were salty and cheesy, children with DS/NTS had a greater tolerance for more textures in general, including crunchy and grainy. Overall, this research identified mealtime behaviors in children with DS, determined overall disposition of children with DS to foods of differences sensory properties, and demonstrated the influence of TS on a child's disposition to a food. This research will be extended to develop acceptable and innovative food products for children with DS/TS.

Weight Status and Associated Risk Factors of Mealtime Behaviours among Children with Autism Spectrum Disorder.

Atypical mealtime behaviours in children with autism spectrum disorder (ASD) have been linked with oral sensory hypersensitivity that may contribute to food selectivity and weight issues. This cross-sectional study aims to determine the association between atypical mealtime behaviours and associated risk factors besides exploring the prevalence of overweight and obesity among Malaysian children with ASD in community settings. A total of 150 children with ASD aged 3–11 years participated in this study. A self-administered questionnaire on sociodemographic variables, mealtime behaviours and oral sensory processing was completed by the caregivers. The prevalence of overweight in the study samples was 18.5%, whereas obesity was 20.0%. In a multivariate analysis model, oral sensory processing (B = 0.608, 95% CI = 0.493, 0.722, p < 0.001), severity of autism symptoms (moderate and severe) (B = 2.585, 95% CI = 0.722, 4.448, p = 0.007) and younger children with ASD (B = −0.694, 95% CI = −1.189, −0.199, p = 0.006) were found as independent predictors of atypical mealtime behaviours. Children with ASD aged 3–11 years old have a higher prevalence of being overweight and obese, thus requiring regular anthropometric screening in community settings by relevant healthcare professionals. Furthermore, a relationship was found between oral sensory difficulties and atypical mealtime behaviours in children with ASD. A multidisciplinary approach is crucial in the overall management of food selectivity in this population.

Feeding Skill and Behavior Changes in Children With Complex Feeding Disorders Following Therapy in an Intensive Multidisciplinary Feeding Program

Purpose: This study aims to measure and describe changes in oral feeding skills and mealtime behaviors observed in children with complex feeding disorders and/or feeding tube dependence after participation in an intensive multidisciplinary feeding program. This is the first study to use a standardized tool to report feeding outcomes after patients received intensive feeding therapy using a combination of therapeutic strategies. Method: This was a prospective observational study examining the treatment outcomes of 34 patients (range: 13 months to 6.5 years) admitted into the Intensive Multidisciplinary Feeding Program using the Pediatric Eating Assessment Tool (PediEAT). Eighteen patients were tube dependent; 16 patients were oral feeders. All patients received 19 days of intensive feeding intervention. The PediEAT was completed by patient's caregiver at admission and discharge from the feeding program. Caregiver and patient demographics were also collected. Results: Statistical analysis of scores at admission (prescore) and at discharge (postscore) revealed significant improvements in PediEAT total scores and across all subscales for all patients. The largest degree of change was noted in the Problematic Mealtime Behaviors subscale. Patients who were oral feeders also demonstrated significant improvements in the Oral Processing subscale in addition to Problematic Mealtime Behaviors subscale. Tube-dependent patients presented with a large degree of change in the Selective Restrictive Eating subscale and in the Problematic Mealtime Behaviors subscale. Conclusions: This study demonstrates that the use of an individualized approach using a combination of therapeutic strategies results in statistically significant improvements in multiple feeding domains as measured by a validated tool after participating in an intensive multidisciplinary feeding program. Improvement in a child's ability to manage advanced textures and consistencies can have a significant impact on their willingness to engage in mealtimes. It is important to measure and report on their skills, in addition to behavioral responses and intake.

Randomized trial of a self-administered parenting intervention for selective eating in young children

Selective eating is a common childhood feeding problem associated with family stress and micronutrient deficiencies. While there are empirically-supported behavioral strategies for addressing selective eating, there are significant systems-level barriers to implementing them. The aim of this study was to develop and test a self-administered intervention for parents of children with selective eating. Participants were 156 parents of children with selective eating ages 18 months-6 years who were randomly assigned to either the handout + video condition (8-module video intervention and detailed handout) or handout condition (detailed handout only). Outcome measures were administered pre-intervention and 4 weeks post-intervention. Only 23 % of participants in the handouts plus video condition played more than one video module. Both groups had significant decreases in maladaptive mealtime parenting practices, undesired child mealtime behaviors, and number of foods offered. No significant effect of study condition was found on the outcome measures. Further research is needed to determine how to encourage engagement of parents with self-administered intervention materials.

Household Mealtimes During the 2020 COVID-19 Lockdown in Aotearoa New Zealand: The Influence of Household Type and Psychological Distress.

COVID-19 lockdown meant disruptions to daily routines for households in Aotearoa New Zealand. The research presented here investigates how mealtimes changed for people living in New Zealand during the first COVID-19 lockdown in mid-2020 and sought to determine if household composition type and psychological distress impacted the frequency of engaging in several mealtime behaviors. The COVID Kai Survey collected data using an anonymous, online survey and asked questions on sociodemographic characteristics including household composition, frequency of engaging in different mealtime behaviors before and during lockdown, and psychological distress, which was measured using the Kessler 6 screening tool. The findings of this study shows an increase in the perceived importance of mealtimes (n = 807, 26.9% before lockdown, n = 1,154, 38.5% during lockdown) and an increase in the proportion of the survey respondents who stated that they frequently ate meals at the dinner table (n = 1,343, 44.8% before lockdown, n = 1,481, 49.4% during lockdown). There was a decrease, across all household composition types, in the proportion of respondents who ate out frequently at a restaurant or café (n = 878, 29.3% before lockdown, n = 5, 0.2% during lockdown, P < 0.001). The use of meal kits, e-dining, and eating meals in front of screens is also presented and discussed. All results are discussed with reference to Aotearoa New Zealand’s stringent lockdown restrictions. Respondents who experienced psychological distress during lockdown were 1.47 times more likely to consider mealtimes an important part of their day and respondents living in households with one adult and at least one child who also experienced psychological distress were 5.95 times more likely to eat dinner at the dinner table than those who did not report psychological distress. Findings of this study further the understanding of the wider societal impact of COVID-19 lockdown on everyday life.

A nutrition education intervention to improve eating behaviors of children with autism spectrum disorder: Study protocol for a pilot randomized controlled trial

Autism spectrum disorder (ASD) is a developmental disorder that affects communication and social behaviors. Children with ASD often experience mealtime behavior challenges and selective eating behaviors. They also tend to consume fewer fruits and vegetables and more high-energy dense foods, compared to neurotypical peers. A nutrition intervention was designed to prevent the development of feeding disorders and the long-term negative health impacts associated with poor dietary intake. This randomized controlled trial will evaluate the feasibility and preliminary efficacy of the nutrition education intervention for children with ASD and their parents through the Early Intervention (EI) services. We will recruit EI providers and parent-child dyads (n = 48) from EI programs, and randomly assign them into Autism Eats intervention (n = 24) or enhance usual care (EUC) comparison group (n = 24). The Autism Eats is 10 weekly sessions delivered individually as part of EI, while the EUC group will receive only 1 nutrition education session and then weekly parent handouts. The Autism Eats integrates ASD-specific feeding strategies and behaviorally-focused intervention strategies such as goal setting. Feasibility indicators include reach/participation, attrition, completion, fidelity, compatibility, and qualitative participant feedback. Outcome measures include dietary intakes and mealtime behaviors of children with ASD using 3-day food records and a validated questionnaire, the Brief Autism Mealtime Behavior Inventory (BAMBI). We will examine whether there are differences in children's food intakes, variety, diet quality, and mealtime behaviors between Autism Eats and EUC groups at post-intervention and 5-month follow-up assessment. This study will provide critical data to inform a full-scale randomized controlled trial.

Feeding problems in children with autism spectrum disorders: a systematic review

ABSTRACT Feeding problems are often associated with Autism Spectrum Disorders. However, many terms are used to describe these problems with a lack of consensus between authors. This systematic review critically examines the available scientific literature on the most commonly described characteristics of feeding disorders among children with Autism Spectrum Disorders. The literature was evaluated according to PRISMA standards by searching electronic databases (e.g., MEDLINE, EBSCO) with reference lists from January 2009 to January 2019. English language studies were included. and full-text article reviews were conducted by two independent authors with sequential data extraction. The systematic search and the subsequent analysis of the results revealed 45 articles eligible for full review. Detailed information regarding the methods and results was extracted from the original articles, and the quality of the included studies was appraised. The most commonly described feeding problem was food selectivity followed by mealtime behaviour problems. We also found some frequently associated issues like sensory sensitivity as well as anthropometric deviations and nutritional deficits that can negatively impact health. Oral motor impairment was a less commonly studied phenomenon. Most of the reviewed studies were considered to have a ‘moderate’ level of evidence. Although current evidence suggests that feeding problems are often associated with autism, more research is needed to understand the reliability and validity between and within existing feeding definitions and measures, as well as into the prevalence of oral sensory-motor related deficits.

Brief Report: Plasma Leptin and Mealtime Feeding Behaviors Among Children with Autism Spectrum Disorder: A Pilot Study.

We examined the relationship between weight status, appetite regulating hormones, and mealtime behaviors among children, (5-12years old), diagnosed with Autism Spectrum Disorder (ASD) in a cross-sectional study. All (N = 21) completed anthropometry measurements and (n = 18)provided blood samples for hormone analysis. Mealtime behavior, dietary, physical activity, puberty stage, and social impairment data were collected. Under fasting conditions, overweight/obese (OWOB) participants, (n = 6), had higher leptin concentrations (p < 0.02) and more feeding challenges (p < 0.05) than normal weight (n = 15). Higher leptin levels and disruptions in mealtime behaviors may exist among OWOB children in this study. Future longitudinal studies that examine appetite regulating hormones and mealtime behaviors may inform our understanding of the role of these markers in the development of obesity in ASD.

Online Parenting Intervention for Children's Eating and Mealtime Behaviors: Protocol of a Randomized Controlled Trial.

Introduction: Obesity and overweight are significant health problems among Australian children. Parents play a vital role in establishing healthy eating behaviors in their children. However, parents often experience difficulties in implementing effective parenting practices and lack confidence in their ability to help children adopt these behaviors. This trial will evaluate the efficacy of an online program, Healthy Habits Triple P, in improving children’s snacking and mealtime behaviors and related parenting practices. Methods and analysis: This is a single-blinded, randomized controlled trial for parents of young Australian children aged 2–6 years. Participants will be recruited through childcare centers, social media, online parent forums and existing networks. The participants in the intervention arm will receive access to a web-based parenting intervention in addition to nutrition-related information for parents published by the National Health and Medical Research Council of Australia; those in the control arm will receive nutrition-related information only. After the completion of the study, the parenting intervention will be offered to the control arm. The primary outcome will be improvement in children’s eating habits. The secondary outcomes include parents’ self-efficacy, confidence, children’s mealtime behaviors and mealtime parenting strategies. Both primary and secondary outcomes will be evaluated through online-administered, validated parent-reported questionnaires. We will also undertake a quantitative and qualitative evaluation of the practicality and acceptability of the intervention.

Person-Centered and Task-Centered Care and Mealtime Behaviors in Nursing Home Residents With Dementia: Impact on Food Intake.

Background and ObjectivesNursing home (NH) staff mealtime care approaches are associated with behaviors of residents with dementia, but their impact on food intake remains unexplored. This study examined the role of staff person-centered and task-centered approaches and resident positive, neutral, and challenging behaviors on food intake.Research Design and MethodsVideotaped mealtime observations (N = 160) involving 36 staff and 27 residents (53 unique staff–resident dyads) in 9 NHs were coded using the refined Cue Utilization and Engagement in Dementia mealtime video-coding scheme. The dependent variable was resident food intake. The independent variables were staff person-centered approaches that support resident abilities, staff–resident (dyadic) interactions, and dining environments, staff task-centered approaches, and resident positive, neutral, and challenging behaviors. Resident challenging behaviors included mealtime functional impairments and resistive behaviors. Linear mixed modeling was used. Moderating effects of staff approaches, food type, and length of dyadic mealtime interactions (ie, video duration) were examined.ResultsThe relationship between food intake and resident mealtime functional impairments was moderated by food type (p < .001). The relationship between food intake and resident resistive behaviors was moderated by food type (p = .002) and staff person-centered verbal approaches (p = .001). The relationships between food intake and staff person-centered nonverbal approaches (p = .003) and resident positive/neutral nonverbal behaviors (p = .004) were moderated by the length of dyadic mealtime interactions.Discussion and ImplicationsFood intake was associated with staff person-centered approaches and resident positive/neutral and challenging behaviors. Findings emphasize the importance of facilitating positive dyadic interactions using individualized, context-based, multifaceted, person-centered care. Future research on temporal and causal relationships is warranted in larger diverse samples.

Convergent validity of the Autism Spectrum Disorder Mealtime Behavior Questionnaire (ASD-MBQ) for children with autism spectrum disorder

There was a growing interest in difficulties with eating as one of the most problematic symptoms in children with autism spectrum disorder (ASD). The purpose of this study is to examine the convergent validity of the Autism Spectrum Disorder Mealtime Behavior Questionnaire (ASD-MBQ) with the Asahide’s test for social adjustment skills, the Japanese version of the short version of the sensory profile questionnaire, the Japanese version of the Social Communication Questionnaire, and the Parenting Strain Index in Japanese children with ASD. The final sample contained 294 children who were diagnosed as the ASD based on the DSM-5 criteria, the mean age of children was 10 ± 4 years (range: 3–18 years). The ASD-MBQ is a questionnaire that comprised of 42 items that are classified into five subdomains: selective eating, clumsiness/manners, interest in/concentration on eating, oral-motor function, and overeating. Spearman’s rank correlation coefficient revealed that the ASD-MBQ showed the moderate to high correlation coefficient with all four external criteria. Our results in this study supported the sufficient convergent validity in the ASD-MBQ. Therefore, the ASD-MBQ could be a useful tool for research and practice in a wide range of children with ASD aged 3 to 18.

Eosinophilic esophagitis in cystic fibrosis: A case series with long-term follow-up.

Challenging mealtime behaviors in young children and difficulties in meeting their dietary intake recommendations are sources of parenting stress and associated with negative quality of life. The gastrointestinal (GI) manifestations of cystic fibrosis (CF) can often present similarly to a GI pathology unrelated to CF. Specifically, this case series focuses on three toddlers with CF who presented with oral aversion and challenging mealtime behaviors and later were diagnosed with eosinophilic esophagitis (EoE). Though EoE often presents with dysphagia, younger patients commonly present with nonspecific GI symptoms such as regurgitation, emesis, abdominal pain, failure to thrive, food intolerance, and oral aversion. Given the overlap of GI manifestations in CF and EoE, it can be challenging for clinicians to diagnose the coexistent EoE in patients with CF. We describe the presenting symptoms, treatment, and successful outcomes of three pediatric patients with CF and EoE. To our knowledge, this is the second case series with a detailed description of EoE in CF.

Mapping the gaps: A scoping review of research on pediatric feeding disorder.

Pediatric feeding disorder (PFD) is defined as impaired oral intake that is not age-appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction. As PFD is prevalent and increasing, so are publications on the topic; however, the research literature is often disparate in terminology used and siloed by discipline. Greater understanding of the current research concerning PFD will help identify areas in need of further study. The purpose of this scoping review is to examine the extent, range, and nature of research activities concerning PFD and to identify gaps in the empirical literature. Three electronic databases (PubMed/Medline, CINAHL, PsycINFO) were searched using terms related to pediatric feeding disorder, which include, but not limited to, "feeding disorder/problem/difficulty", "avoidant restrictive food intake disorder (ARFID)", "dysphagia", "selective/picky eating", "problematic mealtime behaviors" or "food refusal". The following limits were placed on the search: full text, humans, English, and age limit (up to 18 years old), and publication date (last 10 years). Covidence software was used to facilitate a systematic data management/analysis. Two people in the research team independently reviewed each result (screening titles and abstracts first, then moving to the full texts) to identify studies that met our inclusion/exclusion criteria and conflicts were resolved through a team discussion. Data were charted regarding disciplines of the authors, study purposes, study settings/locations, study methodologies, and study participants. Descriptive statistics and thematic analyses were used to summarize the characteristics of the studies. The initial search resulted in 5354 articles after removing duplicates between the databases. With a final set of articles (n=415), data charting was completed. The majority of studies were completed by authors from Psychology (n=171) and Medicine (n=123). The most studied aims were to examine attributes of feeding problems (n=168) and/or factors associated with feeding problems (n=183). Sample size median was 53. A total of 166 of the 415 studies examined the effect of an intervention, treatment, or program, but dose of the intervention was difficult or impossible to report across studies. Feeding was studied as an outcome in 400 out of the 415 studies. A closer accounting of the systematically developed parent-report tools revealed 50 distinct parent report tools used across the subset of studies utilizing parent report outcomes (n=123). The results of this scoping review highlight the designs and methods used in research on PFD. This reveals critical gaps in knowledge generation and barriers to intervention replication.

Relapse during the treatment of pediatric feeding disorders.

Resurgence and renewal are treatment-relapse phenomena in which previously extinguished behavior returns after the conditions for an alternative response worsen or the context changes, respectively. Recently, researchers have evaluated the prevalence of resurgence and renewal when treating destructive behavior with functional communication training. However, resurgence of inappropriate mealtime behavior has yet to be evaluated; perhaps because treatments involve qualitatively different resurgence opportunities (e.g., increased bite-presentation rate). We evaluated the prevalence of resurgence and renewal of inappropriate mealtime behavior across 22 and 25 applications of extinction-based treatments, respectively. Resurgence occurred in 41% (9/22) of applications, most often following presentation-rate increases. Renewal occurred in 52% (13/25) of applications, most often following feeder changes from therapist to caregiver. We discuss these findings in terms of their ability to inform relapse-mitigation strategies for resurgence and renewal of inappropriate mealtime behavior.

Characteristics of the autism spectrum disorder gastrointestinal and related behaviors inventory in children.

Gastrointestinal (GI) symptoms are one of the prevalent co‐occurring issues in autism spectrum disorder (ASD), though the range of symptom frequency estimates varies dramatically across studies, which can limit the further research of GI issues in ASD as well as potential treatment strategies. The wide range of prevalence estimates is partly due to the lack of standardized, validated measures of GI symptoms among people with ASD. The goal of this study was to (1) develop a measure, which included non‐verbal and mealtime behaviors, to assess for GI symptoms and (2) evaluate its psychometric characteristics. This was accomplished by drawing on two existing tools, Autism Treatment Network Gastrointestinal Inventory and the Brief Autism Mealtime Behavior Inventory, and deriving new items, to create the “ASD Gastrointestinal and Related Behaviors Inventory” (ASD‐GIRBI). The ASD‐GIRBI was piloted in an online registry of families with a child with ASD. A psychometric analysis was carried out in a sample of 334 children aged 6–17 years with ASD, resulting in a 36‐item tool. The Cronbach's alpha for the overall scale was 0.88. Exploratory factor analysis identified a seven‐factor model (1. Bowel movement pain; 2. Aggressive or disruptive during mealtimes; 3. Particular with foods; 4. Abdominal pain and upset stomach; 5. Refusing food; 6. Constipation and encopresis; 7. Motor or other behaviors). Following validation in an independent sample with clinical evaluation of GI symptoms, this tool will be helpful for both research and clinical purposes.
