RESUMO

New school transitions can be challenging for students on the autism spectrum. No published, evidence-based interventions exist to support families and teachers of students transitioning to elementary and secondary school during this critical period. Using Community Partnered Participatory Research, we developed Building Better Bridges (BBB), a caregiver coaching intervention that includes training on effective school communication, educational rights, advocacy, and child preparation strategies. We compared BBB (n = 83) to a module/resources-only comparison (n = 87) in a four-site randomized controlled trial in racially and ethnically diverse, under-resourced communities. In our intent-to-treat analysis, caregivers and teachers in BBB rated students' transitions to the new classroom as more positive, relative to the comparison group. Results suggest this low-cost intervention can improve the transition process for families and students at high risk of poor transitions.

RESUMO

Heterogeneity among individuals on the autism spectrum is widely acknowledged as a barrier to develop effective interventions. Overcoming this challenge requires characterization of individual differences, especially for children that are minimally verbal and often excluded from research studies. Most studies that describe autistic subgroups identify a single minimally verbal verbal group based on a single identifying measure (e.g., ADOS module one or single item indicating absence of phrase speech). Determining personalized courses of intervention requires a more detailed understanding since a single intervention will not be effective for all who are minimally verbal. The present study identified comprehensive profiles of cognitive, language, and social communication skills within a large, diverse, group of minimally verbal children with autism. The analysis combined baseline data from two studies to yield a sample of 344 participants, who were 3 to 8 years old at the time of study onset, with 60% who identified as having a race/ethnicity other than White. Via latent profile analysis (LPA), a three-group model was identified as best fit to the data. Profile identification was dependent on a participant's combination of cognitive, expressive, and social communication characteristics, rather than a single domain. One group (n = 206) had global delays, while the other two groups (n = 95 and n = 43) had variable strengths in cognition and communication. Findings suggest that low-frequency/minimally verbal communicators with autism have heterogeneous characteristics that can be systematically organized.

RESUMO

Preschool autistic children with significant global developmental delays and very limited language skills are at high risk for remaining minimally verbal at entry into primary school. This study compared two early intervention models for improving social communication and spoken language outcomes in 164 children who received intervention in their community preschool program for 6 months, with a six-month follow-up. The primary outcome measure was a standardized language assessment, and secondary measures focused on social communication. Results indicated children on average made 6 months gain in language development in the active 6 months of intervention with no difference between intervention models. Children who initiated joint attention more frequently, or who had higher receptive language at baseline made more progress if assigned to receive JASPER, a naturalistic developmental behavioral intervention. Children who received Discrete Trial Training made greater spoken language progress from exit to follow-up. These findings suggest that progress can be made in autistic children who have very little spoken language and who receive targeted early interventions. Individual trajectories vary and depend in part on initial abilities in social communication and receptive language. Future research might consider methods to systematically personalize approaches to fit child characteristics and family preference. LAY SUMMARY: This study compared two different early intervention approaches for teaching spoken language to minimally verbal, globally delayed autistic preschoolers. Children were given an hour of therapy daily for 6 months and then reassessed 6 months later. The majority of the 164 participants were from historically excluded populations (low income and minority), and therapy was delivered in school community settings by expert clinicians. Results indicated that the participants made significant progress regardless of intervention approach: 6 months gain in standardized language scores over 6 months, but slower progress during the period after therapy ended. Children who initiated joint attention more frequently, or who had higher language understanding at baseline made more progress if assigned to receive JASPER, a naturalistic developmental behavioral intervention. Children who received Discrete Trial Training made greater language progress during 6-month period after therapy ended. These findings suggest that progress can be made in children with ASD who have very little spoken language and who receive targeted early interventions.

RESUMO

OBJECTIVE: To determine if cesarean delivery is adversely associated with child neurodevelopment as measured at 20 months and 7 years. METHODS: In a prospective cohort study (n = 1328) in the Republic of Seychelles, we examined the association between mode of delivery and 22 measures of child neurodevelopment spanning multiple domains: cognition, executive and psychomotor function, language development, behavior, scholastic achievement, and social communication. Using multivariable linear regression, we evaluated the relationship between delivery mode (Cesarean/vaginal delivery) and each developmental outcome, while controlling for relevant covariates including child sex and age, maternal age, maternal IQ, whether both parents lived with the child, and Hollingshead socioeconomic status. RESULTS: At 20 months, children born via cesarean delivery had slightly higher scores (ß = 0.11, 95% confidence interval: 0.00, 0.21) on the Infant Behavior Questionnaire-Revised Positive Affectivity/Surgency subtest, a measure of infant temperament, as compared to vaginal delivery. Delivery mode was not associated with any of the 7-year developmental outcomes. CONCLUSIONS FOR PRACTICE: Our study does not support the notion that cesarean delivery is associated with child neurodevelopmental outcomes.

RESUMO

This paper examines the reliability and validity of parent target problems (PTPs) in a multi-site randomized controlled trial of parent training (PT) versus psychoeducation (PEP) in children (150 boys, 19 girls; mean age 4.7 ± 1.2 years) with autism spectrum disorder (ASD) and disruptive behavior. At baseline, treatment blind, independent evaluators asked parents to nominate the child's top two problems. Each problem was documented in a brief narrative. Narratives were reviewed and revised at follow-up visits during the six-month trial. When the trial was completed, five judges, blind to treatment condition, independently rated change from baseline on a 9-point scale (1 = normal; 2 = markedly improved; 3 = definitely improved; 4 = equivocally improved; 5 = no change; 6 = possibly worse; 7 = definitely worse; 8 = markedly worse; 9 = disastrously worse) at Weeks 8, 12, 16, and 24 (inter-rater intraclass correlation = 0.78). PTP scores for the two target problems were averaged across the five raters, yielding a mean score for each child at each time point. Mean PTP scores showed improvement in both treatment groups over the 24-week study. Compared to PEP, PTP ratings showed a steeper decline in PT based on significant interaction of group and time (t(df) = 2.14(155.9), p = 0.034; Week 24 effect size = 0.75). In categorical analysis, we compared cutoffs mean PTP scores of 3.0 (definitely improved), 3.25, and 3.5 with the positive response rate on the Clinical Global Impressions-Improvement scale from the original study. Sensitivities ranged from 52-78%. PTP narratives offer a systematic, reliable, and valid way to track child-specific outcomes in clinical trials and clinical practice.

RESUMO

Children with autism situated in lower income families often receive intensive educational interventions as their primary form of treatment, due to financial barriers for community interventions. However, the continuity of care can be disrupted by school transitions. The quality of social relationships during the transition to a new school among parents, school staff and community providers, called the team-around-the-child (TAC), can potentially buffer a child with autism from the adverse effects caused by care disruptions. Qualities of social relationships, including trust and collaborative problem solving, can be measured using social network analysis. This study investigates if two different types of TAC relationships, defined as (1) the level of trust among team members and (2) the degree of collaborative problem solving among team members, are associated with perceived successful transitions for children with autism from lower income families. Findings suggested that TAC trust is significantly associated with the outcome of transition success for children with autism immediately post-transition.

RESUMO

To date there are no evidence-based comprehensive interventions for use in school settings. There are numerous barriers to delivery of high-quality interventions in schools that have limited the transfer of research-based interventions to school settings. Modular Approach to Autism Programing for Schools (MAAPS) is a framework for implementation of evidence-based interventions in school settings that is designed to address these barriers. The development and initial evaluation of MAAPS was conducted using an implementation-science framework and results indicate that MAAPS is aligned with needs and resources available in schools, that it had excellent social validity, and that there is good evidence that MAAPS is effective for addressing core and associated features of autism in educational settings.

RESUMO

Parents of children with autism spectrum disorder (ASD) face higher levels of caregiver strain compared to parents of children with other disabilities. This study examined child clinical features that predict high levels of caregiver strain for 374 parents of children with ASD. Caregiver strain was measured using the Caregiver Strain Questionnaire (CGSQ) objective, subjective internalized, and subjective externalized subscales. Confirmatory factor analysis indicated an acceptable fit for the original CGSQ three-factor solution. The strongest child predictors across CGSQ subscales were: disruptive behavior for objective strain, autism severity and disruptive behavior for subjective internalized strain, and oppositional behavior and hyperactivity for subjective externalized strain. Individualized interventions that attend to specific elements of parental strain may reduce strain and improve family wellbeing.

RESUMO

INTRODUCTION: Children with autism spectrum disorder (ASD) benefit when their caregivers can effectively advocate for appropriate services. Barriers to caregiver engagement such as provider mistrust, cultural differences, stigma, and lack of knowledge can interfere with timely service access. We describe Mind the Gap (MTG), an intervention that provides education about ASD, service navigation, and other topics relevant to families whose children have a new ASD diagnosis. MTG was developed via community partnerships and is explicitly structured to reduce engagement barriers (e.g., through peer matching, meeting flexibility, culturally-informed practices). We also present on the results of a pilot of MTG, conducted in preparation for a randomized controlled trial. METHODS: MTG was evaluated using mixed methods that included qualitative analysis and pre/post-test without concurrent comparison group. Participants (n=9) were primary caregivers of children (ages 2-7 years) with a recent ASD diagnosis and whose annual income was at or below 185% of the federal poverty level. In order to facilitate trust and relationship building, peer coaches delivered MTG. The coaches were parents of children with ASD who we trained to deliver the intervention. MTG consisted of up to 12 meetings between coaches and caregivers over the course of 18 weeks. Coaches delivered the intervention in homes and other community locations. Coaches shared information about various "modules," which were topics identified as important for families with a new ASD diagnosis. Coaches worked with families to answer questions, set weekly goals, assess progress, and offer guidance. For the pilot, we focused on three primary outcomes: feasibility, engagement, and satisfaction. Feasibility was measured via enrollment and retention data, as well as coach fidelity (i.e., implementation of MTG procedures). Engagement was measured via number of sessions attended and percentage completion of the selected outcome measures. For completers (n=7), satisfaction was measured via a questionnaire (completed by caregivers) and open-ended interviews (completed by caregivers and coaches). RESULTS: We enrolled 56% of referred caregivers and 100% of eligible families. Retention was high (78%). Coaches could deliver the intervention with fidelity, completing, on average, 83% of program components. Engagement also was high; caregivers attended an average of 85% of total possible sessions and completed 100% of their measures. Caregivers indicated moderately high satisfaction with MTG. Qualitative data indicated that caregivers and coaches were positive about intervention content, and the coach-caregiver relationship was important. They also had suggestions for changes. CONCLUSION: Mind the Gap demonstrates evidence of feasibility, and data from the pilot suggest that it addresses intervention engagement barriers for a population that is under-represented in research. The results and suggestions from participants were used to inform a large-scale RCT, which is currently underway. Overall, MTG shows promise as an intervention that can be feasibly implemented with under-resourced and ethnic minority families of children with ASD. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov: NCT03711799.

RESUMO

Anxiety is a common and impairing problem in children with autism spectrum disorder, but little is known about it in preschool children with autism spectrum disorder. This article reports on the characteristics of anxiety symptoms in young children with autism spectrum disorder using a parent-completed rating scale. One hundred and eighty children (age 3-7 years) participated in a clinical trial of parent training for disruptive behaviors. Anxiety was measured as part of pre-treatment subject characterization with 16 items from the Early Childhood Inventory, a parent-completed scale on child psychiatric symptoms. Parents also completed other measures of behavioral problems. Sixty-seven percent of children were rated by their parents as having two or more clinically significant symptoms of anxiety. There were no differences in the Early Childhood Inventory anxiety severity scores of children with IQ < 70 and those with ⩾70. Higher levels of anxiety were associated with severity of oppositional defiant behavior and social disability. Anxiety symptoms are common in preschoolers with autism spectrum disorder. These findings are consistent with earlier work in school-age children with autism spectrum disorder. There were no differences in anxiety between children with IQ below 70 and those with IQ of 70 and above. Social withdrawal and oppositional behavior were associated with anxiety in young children with autism spectrum disorder.

RESUMO

This study examined whether outcomes in early intensive behavioral intervention (EIBI) during a university-led multisite project could be replicated by the same community agency independently of the project. Participants, age 18 to 75 months at onset of intervention, were 48 children with autism spectrum disorder (ASD) enrolled in 35 hr per week of publicly funded, community-based EIBI for 3 years and 46 children who were matched on baseline characteristics and received early childhood services as usual (SAU) through local early childhood special education providers. Linear mixed models indicated that EIBI participants improved significantly more than SAU participants on standardized tests of IQ, nonverbal IQ, adaptive behavior, and academic achievement, administered by independent evaluators. Although limited by the use of a matched comparison group rather than random assignment, the study provides evidence for the sustainability of effective EIBI in community settings for children with ASD who start intervention at varying ages throughout early childhood.

RESUMO

Immune dysregulation during pregnancy may influence behavior and neurodevelopment in offspring, but few human studies have tested this hypothesis. Using structural equation modeling, we examined associations between maternal inflammatory markers at 28 weeks gestation and child neurodevelopmental outcomes at 20 months of age in a sample of 1453 mother-child pairs. We observed several associations between maternal inflammatory markers measured in the late second or early third trimester and child neurodevelopmental outcomes. The direction of association for some markers was unexpected. Further research is warranted to confirm and elucidate the exact nature of these findings.

RESUMO

BACKGROUND AND OBJECTIVE: Autism spectrum disorder (ASD) is a heterogeneous disorder. Research has explored potential ASD subgroups with preliminary evidence supporting the existence of behaviorally and genetically distinct subgroups; however, research has yet to leverage machine learning to identify phenotypes on a scale large enough to robustly examine treatment response across such subgroups. The purpose of the present study was to apply Gaussian Mixture Models and Hierarchical Clustering to identify behavioral phenotypes of ASD and examine treatment response across the learned phenotypes. MATERIALS AND METHODS: The present study included a sample of children with ASD (N = 2400), the largest of its kind to date. Unsupervised machine learning was applied to model ASD subgroups as well as their taxonomic relationships. Retrospective treatment data were available for a portion of the sample (n = 1034). Treatment response was examined within each subgroup via regression. RESULTS: The application of a Gaussian Mixture Model revealed 16 subgroups. Further examination of the subgroups through Hierarchical Agglomerative Clustering suggested 2 overlying behavioral phenotypes with unique deficit profiles each composed of subgroups that differed in severity of those deficits. Furthermore, differentiated response to treatment was found across subtypes, with a substantially higher amount of variance accounted for due to the homogenization effect of the clustering. DISCUSSION: The high amount of variance explained by the regression models indicates that clustering provides a basis for homogenization, and thus an opportunity to tailor treatment based on cluster memberships. These findings have significant implications on prognosis and targeted treatment of ASD, and pave the way for personalized intervention based on unsupervised machine learning.

RESUMO

OBJECTIVES: Parents of children with autism spectrum disorder (ASD) report high levels of stress that can interfere with important child and family treatments. Limited past research considers how the caregiving experience and social determinants of health may contribute to treatment engagement and outcomes, particularly in under-represented families, who already experience service and health disparities. We aimed to assess the experiences of caring for an individual with ASD, with specific emphasis on perceptions of stress. METHODS: Three key informant interviews were conducted with parents (n=1) and providers (n=2) of children with ASD to refine interview guide questions. Once questions were refined, four focus groups (n=17) and one key informant interview were conducted with parents of children with ASD who were (a) non-white, (b) Spanish speakers, (c) of limited financial resources, and/or (d) living in rural counties. All participants lived in Western New York, with the majority residing in Rochester. Content analysis by two independent coders was used to identify and refine themes. RESULTS: Themes included: (a) caregiving for an individual with ASD can cause interference with family functioning, (b) misperceptions of ASD contribute to caregiver stress, (c) culture contributes to stressors for parents, and (d) service navigation difficulties are a significant source of stress. Suggestions for interventions to address parents stress included: modular and integrative treatments for multiple content areas, addressing cultural barriers to treatment engagement, and education on ASD to the community. CONCLUSIONS: Parent-focused interventions for caregivers of children with ASD should specifically explore and address service and health disparities for parents, especially those predicated on race, ethnicity, rurality, and language of origin. Interventions should also be individualized to parent characteristics and experiences. In future research on parent training, the unique contributions of caregiver stress and other characteristics (e.g., race-related stress, geographic location) should be included as potential modifiers of treatment.

RESUMO

Decades of research have established that racial ethnic minority, low-income, and/or non-English speaking children with autism spectrum disorder (ASD) are diagnosed later than white children, and their families experience greater difficulty accessing services in the USA. Delayed access to timely diagnosis and early intervention may impact child outcomes and family quality of life. Despite their cognition of these disparities and their significant impact on the lives of those affected, explanations for the barriers experienced by underserved families are elusive, likely due to the complex interaction between structural and family factors. This study used qualitative methods to gather family and provider perspectives of perceived barriers and facilitators to obtaining an ASD diagnosis and accessing ASD-related services for underserved families. Themes from focus groups and interviews with families from three cultural groups (black, Hispanic/Latino, and Korean) and three primary languages (English, Korean, and Spanish) highlight specific barriers related to family, community, and systemic challenges as well as facilitators to accessing care for these populations. Family experiences are expanded upon with viewpoints from the providers who work with them. Recommendations are made for reducing disparities in the existing ASD service system including increasing professional, family, and community education; increasing culturally responsive care; improving provider-family partnerships; and addressing practical challenges to service access.

RESUMO

Transitioning to a new school is often challenging for students with autism spectrum disorder. Few studies have examined the transition needs of students with autism spectrum disorder or the benefits of specific supports. This review synthesizes research findings on the difficulties that school transitions pose for students with autism spectrum disorder and their parents and teachers, and the strategies used to support students and parents during school transition. The review included 27 studies (10 examining the transition to primary school, 17 the transition to secondary school), with data from 443 students with autism spectrum disorder, 453 parents, and 546 teachers, across four continents (North America, Europe, Africa, and Australia). Studies reported that children with autism spectrum disorder struggled with anxiety and increased social pressure, their parents felt overwhelmed with complex placement decisions and worried about the well-being of their children, and teachers strove to provide appropriate supports to their students with autism spectrum disorder, often with inadequate resources. Findings indicated that the most useful strategies involved helping the student adjust to the new school setting, individualizing transition supports, clarifying the transition process for parents, and fostering communication both between the sending and receiving schools, and school and home.

RESUMO

Objective: Many children with autism spectrum disorder (ASD) have feeding and mealtime problems. To address these, we conducted a pilot randomized trial of a new 11-session, individually delivered parent training program that integrated behavioral strategies and nutritional guidance (PT-F). Methods: Forty-two young children (age: 2 to 7-11 years) with ASD and feeding problems were assigned to 11 sessions of PT-F intervention over 20 weeks or a waitlist control. Outcomes included attendance, parent satisfaction, therapist fidelity, and preliminary assessments of child and parent outcomes. Results: Of the 21 PT-F families, attendance was high (85%) as was parent satisfaction (94% would recommend to others). Treatment fidelity was also high (97%-therapist integrity; 94%-parent adherence). Compared with waitlist, children whose parents participated in PT-F showed significantly greater reductions on the two parent-completed primary outcomes (Brief Autism Mealtime Behavior Inventory-Revised; Twald = -2.79; p = .003; About Your Child's Eating; Twald = -3.58; p = .001). On the independent evaluator-completed secondary eating outcome, the Clinical Global Impression-Improvement, 48.8% of the participants in PT-F were rated as "responders" compared with 0% in waitlist (p = .006). General child disruptive behavior outcomes decreased more in PT-F but not significantly. Parent outcomes of caregiver stress showed nonsignificant trends favoring PT-F with moderate to small effect sizes. Conclusions: This trial provides evidence for feasibility, satisfaction, and fidelity of implementation of PT-F for feeding problems in young children with ASD. Feeding outcomes also appeared favorable and lends support for conducting a larger efficacy trial.

RESUMO

We developed an iOS-based app with a transmitter/disposable sensor and corresponding manualized intervention for children with autism spectrum disorder. The app signaled the onset of urination, time-stamped accidents for analysis, reminded parents to reinforce intervals of continence, provided a visual outlet for parents to communicate reinforcement, and afforded opportunity for timely feedback from clinicians. We compared this intervention with an intervention that uses standard behavioral treatment in a pilot randomized controlled trial of 33 children with autism spectrum disorder aged 3-6 years with urinary incontinence. Parents in both groups received initial training and four booster consultations over 3 months. Results support the feasibility of parent-mediated toilet training studies (e.g., 84% retention rate, 92% fidelity of parent-implemented intervention). Parents used the app and related technology with few difficulties or malfunctions. There were no statistically significant group differences for rate of urine accidents, toilet usage, or satisfaction at close of intervention or 3-month follow-up; however, the alarm group trended toward greater rate of skill acquisition with significantly less day-to-day intervention. Further development of alarm and related technology and future comparative studies with a greater number of participants are warranted.

RESUMO

Bilirubin-induced brain injury in the neonatal period has detrimental effects on neurodevelopment that persist into childhood and adulthood, contributing to childhood developmental disorders. Unconjugated bilirubin is a potent antioxidant that may be useful for protecting against oxidative injuries, but it becomes a potent neurotoxin once it crosses the blood brain barrier. Because bilirubin toxicity involves a myriad of pathological mechanisms, can damage most types of brain cells, and affects brain circuits or loops that influence cognition, learning, behavior, sensory, and language, the clinical effects of bilirubin-induced neurotoxicity are likely to be manifold. One possible effect that several experts have identified is bilirubin-induced neurological dysfunction (subtle kernicterus). However, the underlying biological mechanisms or pathways by which subtle kernicterus could lead to developmental disorders has not been elucidated previously. Our aim in this review is to describe a spectrum of developmental disorders that may reflect subtle kernicterus and outline plausible biological mechanisms for this possible association. We review existing evidence that support or refute the association between unconjugated hyperbilirubinemia and developmental disorders, and limitations associated with these studies.
