Disparities in diagnosis and access to health services for children with autism: data from the National Survey of Children's Health

Service deserts and service oases: Utilizing geographic information systems to evaluate service availability for individuals with autism spectrum disorder

LAY ABSTRACT

Autism spectrum disorder and co-occurring symptoms often require lifelong services. However, access to autism spectrum disorder services is hindered by a lack of available autism spectrum disorder providers. We utilized geographic information systems methods to map autism spectrum disorder provider locations in Michigan. We hypothesized that (1) fewer providers would be located in less versus more populated areas; (2) neighborhoods with low versus high socioeconomic status would have fewer autism spectrum disorder providers; and (3) an interaction would be found between population and socioeconomic status such that neighborhoods with low socioeconomic status and high population would have few available autism spectrum disorder providers. We compiled a list of autism spectrum disorder providers in Michigan, geocoded the location of providers, and used network analysis to assess autism spectrum disorder service availability in relation to population distribution, socioeconomic disadvantage, urbanicity, and immobility. Individuals in rural neighborhoods had fewer available autism spectrum disorder providers than individuals in suburban and urban neighborhoods. In addition, neighborhoods with greater socioeconomic status disadvantage had fewer autism spectrum disorder providers available. Finally, wealthier suburbs had good provider availability while few providers were available in poorer, urban neighborhoods. Knowing autism spectrum disorder providers' availability, and neighborhoods that are particularly poorly serviced, presents the opportunity to utilize evidence-based dissemination and implementation strategies that promote increased autism spectrum disorder providers for underserved individuals.

The Cultural Adaptation of a Transition Program for Latino Families of Youth with Autism Spectrum Disorder

During the transition to adulthood, effective and culturally relevant supports are critical for families of youth with autism spectrum disorder (ASD). There is a dearth of documented program development and research on supports for Spanish-speaking Latino families during this life stage. The present work describes the cultural adaptation process of an evidence-based transition program for Latino families of youth with ASD. A model of the actions necessary to meaningfully conduct a cultural adaptation in this context is described. After implementing the culturally adapted program titled Juntos en la Transición with five Spanish-speaking families, parents reported high social validity of the program through surveys and interviews. The cultural adaptation process followed in this work is important for the further development of programs that address the transition needs of Latino youth with ASD and their families. Our impressions may also be useful to those who aim to develop culturally sensitive and ecologically valid multifamily group intervention programs for families from cultural and linguistic minority groups.

Impact of a digital Modified Checklist for Autism in Toddlers-Revised on likelihood and age of autism diagnosis and referral for developmental evaluation

LAY ABSTRACT

This was a project in primary care for young children (1-2 years old). We tested a parent questionnaire on a tablet. This tablet questionnaire asked questions to see whether the child may have autism. We compared the paper and pencil version of the questionnaire to the tablet questionnaire. We read the medical charts for the children until they were 4 years old to see whether they ended up having autism. We found that doctors were more likely to recommend an autism evaluation when a parent used the tablet questionnaire. We think that the tablet's automatic scoring feature helped the doctors. We also think that the doctors benefited from the advice the tablet gave them.

The Development of a Practical Artificial Intelligence Tool for Diagnosing and Evaluating Autism Spectrum Disorder: Multicenter Study

Background

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder with an unknown etiology. Early diagnosis and intervention are key to improving outcomes for patients with ASD. Structural magnetic resonance imaging (sMRI) has been widely used in clinics to facilitate the diagnosis of brain diseases such as brain tumors. However, sMRI is less frequently used to investigate neurological and psychiatric disorders, such as ASD, owing to the subtle, if any, anatomical changes of the brain.

Objective

This study aimed to investigate the possibility of identifying structural patterns in the brain of patients with ASD as potential biomarkers in the diagnosis and evaluation of ASD in clinics.

Methods

We developed a novel 2-level histogram-based morphometry (HBM) classification framework in which an algorithm based on a 3D version of the histogram of oriented gradients (HOG) was used to extract features from sMRI data. We applied this framework to distinguish patients with ASD from healthy controls using 4 datasets from the second edition of the Autism Brain Imaging Data Exchange, including the ETH Zürich (ETH), NYU Langone Medical Center: Sample 1, Oregon Health and Science University, and Stanford University (SU) sites. We used a stratified 10-fold cross-validation method to evaluate the model performance, and we applied the Naive Bayes approach to identify the predictive ASD-related brain regions based on classification contributions of each HOG feature.

Results

On the basis of the 3D HOG feature extraction method, our proposed HBM framework achieved an area under the curve (AUC) of >0.75 in each dataset, with the highest AUC of 0.849 in the ETH site. We compared the 3D HOG algorithm with the original 2D HOG algorithm, which showed an accuracy improvement of >4% in each dataset, with the highest improvement of 14% (6/42) in the SU site. A comparison of the 3D HOG algorithm with the scale-invariant feature transform algorithm showed an AUC improvement of >18% in each dataset. Furthermore, we identified ASD-related brain regions based on the sMRI images. Some of these regions (eg, frontal gyrus, temporal gyrus, cingulate gyrus, postcentral gyrus, precuneus, caudate, and hippocampus) are known to be implicated in ASD in prior neuroimaging literature. We also identified less well-known regions that may play unrecognized roles in ASD and be worth further investigation.

Conclusions

Our research suggested that it is possible to identify neuroimaging biomarkers that can distinguish patients with ASD from healthy controls based on the more cost-effective sMRI images of the brain. We also demonstrated the potential of applying data-driven artificial intelligence technology in the clinical setting of neurological and psychiatric disorders, which usually harbor subtle anatomical changes in the brain that are often invisible to the human eye.

Adherence to screening and referral guidelines for autism spectrum disorder in toddlers in pediatric primary care

Objectives

Although the American Academy of Pediatrics recommends screening for autism spectrum disorder (ASD) for all young children, disparities in ASD diagnosis and intervention in minority children persist. One potential contributor to disparities could be whether physicians take different actions after an initial positive screen based on patient demographics. This study estimated factors associated with physicians completing the follow-up interview for the Modified Checklist for Autism in Toddlers with Follow-up (M-CHAT-F), and referring children to diagnostic services, audiology, and Early Intervention (EI) immediately after a positive screen.

Methods

Children seen in a large primary care network that has implemented universal ASD screening were included if they screened positive on the M-CHAT parent questionnaire during a 16–30 month well child visit (N = 2882). Demographics, screening results, and referrals were extracted from the electronic health record.

Results

Children from lower-income families or on public insurance were more likely to have been administered the follow-up interview. Among children who screened positive, 26% were already in EI, 31% were newly referred to EI, 11% were referred each to audiology and for comprehensive ASD evaluation. 40.2% received at least one recommended referral; 3.7% received all recommended referrals. In adjusted multivariable models, male sex, white versus black race, living in an English-speaking household, and having public insurance were associated with new EI referral. Male sex, black versus white race, and lower household income were associated with referral to audiology. Being from an English-speaking family, white versus Asian race, and lower household income were associated with referral for ASD evaluation. A concurrent positive screen for general developmental concerns was associated with each referral.

Conclusions

We found low rates of follow-up interview completion and referral after positive ASD screen, with variations in referral by sex, language, socio-economic status, and race. Understanding pediatrician decision-making about ASD screening is critical to improving care and reducing disparities.

Objective Estimates of Direct-Medical Costs Among Persons Aged 3 to 38 Years With and Without Research-Defined Autism Spectrum Disorder Ascertained During Childhood: A Population-Based Birth-Cohort Study

OBJECTIVES

Accurate estimates of autism spectrum disorder (ASD)-associated medical costs are essential for predicting future care needs, allocating resources, identifying best practices, and modeling cost-effectiveness. Most existing studies have either employed subjective cost data or ascertained ASD using self-reported or International Classification of Diseases-coded diagnoses. Such ascertainment is especially problematic for identifying milder ASD among older individuals never diagnosed with ASD.

METHODS

This 1976 through 2000 population-based birth-cohort study was set in Olmsted County, Minnesota. ASD cases and age- and sex-matched unaffected controls were identified by applying uniform operational research criteria for ASD (using the guidelines of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision) after rigorous review of provider-linked medical and public, private, or home school records available for all members from birth to a maximum age of 21 years. Medical cost estimates for the 901 case-control pairs used line-item provider-linked billing data (including all payers) from 2003 through 2014 (ages 3-38 years). Outpatient pharmaceutical costs were unavailable. Temporal changes in diagnostic criteria, clinical practice, public awareness, and access were addressed by separating analyses into 5-year age group and 4-year calendar period cells. Unadjusted and adjusted (age and age plus co-occurring conditions) cost estimates were provided for cases, controls, and case-control differences. Additional factors (co-occurring conditions, percentage hospitalized, intellectual disability) were investigated using unadjusted descriptive analyses.

RESULTS

Cell sample sizes ranged from 93 to 402 for age groups 3 through 19 years and from 45 to 395 for age groups 20 through 38 years. Unadjusted, age-adjusted, and fully adjusted medical costs were significantly higher for cases versus controls in 100% of cells for age groups 3 through 19 years and in 50% (unadjusted), 38% (age adjusted), and 12% (fully adjusted) of cells for age groups 20 through 38 years.

CONCLUSIONS

These unique estimates can help inform the construction of cost-effectiveness models; decisions by payers, providers, and policy makers; and predictions of lifetime costs.

Therapy and Psychotropic Medication Use in Young Children With Autism Spectrum Disorder

BACKGROUND AND OBJECTIVES

Guidelines suggest young children with autism spectrum disorder (ASD) receive intensive nonpharmacologic interventions. Additionally, associated symptoms may be treated with psychotropic medications. Actual intervention use by young children has not been well characterized. Our aim in this study was to describe interventions received by young children (3-6 years old) with ASD. The association with sociodemographic factors was also explored.

METHODS

Data were analyzed from the Autism Speaks Autism Treatment Network (AS-ATN), a research registry of children with ASD from 17 sites in the United States and Canada. AS-ATN participants receive a diagnostic evaluation and treatment recommendations. Parents report intervention use at follow-up visits. At follow-up, 805 participants had data available about therapies received, and 613 had data available about medications received.

RESULTS

The median total hours per week of therapy was 5.5 hours (interquartile range 2.0-15.0), and only 33.4% of participants were reported to be getting behaviorally based therapies. A univariate analysis and a multiple regression model predicting total therapy time showed that a diagnosis of ASD before enrollment in the AS-ATN was a significant predictor. Additionally, 16.3% of participants were on ≥1 psychotropic medication. A univariate analysis and a multiple logistic model predicting psychotropic medication use showed site region as a significant predictor.

CONCLUSIONS

Relatively few young children with ASD are receiving behavioral therapies or total therapy hours at the recommended intensity. There is regional variability in psychotropic medication use. Further research is needed to improve access to evidence-based treatments for young children with ASD.

Disparities in Service Use Among Children With Autism: A Systematic Review

CONTEXT

Research reveals racial, ethnic, and socioeconomic disparities in autism diagnosis; there is limited information on potential disparities related to other dimensions of services.

OBJECTIVE

We reviewed evidence related to disparities in service use, intervention effectiveness, and quality of care provided to children with autism by race, ethnicity, and/or socioeconomic status.

DATA SOURCES

Medline, PsychInfo, Educational Resources Informational Clearinghouse, and the Cumulative Index to Nursing and Allied Health Literature were searched by using a combination of Medical Subject Headings terms and keywords related to autism, disparities, treatment, and services.

STUDY SELECTION

Included studies addressed at least one key question and met eligibility criteria.

DATA EXTRACTION

Two authors reviewed the titles and abstracts of articles and reviewed the full text of potentially relevant articles. Authors extracted information from articles that were deemed appropriate.

RESULTS

Treatment disparities exist for access to care, referral frequency, number of service hours, and proportion of unmet service needs. Evidence revealed that racial and ethnic minority groups and children from low-income families have less access to acute care, specialized services, educational services, and community services compared with higher-income and white families. We found no studies in which differences in intervention effectiveness were examined. Several studies revealed disparities such that African American and Hispanic families and those from low-income households reported lower quality of care.

LIMITATIONS

The body of literature on this topic is small; hence it served as a limitation to this review.

CONCLUSIONS

The documented disparities in access and quality of care may further identify groups in need of outreach, care coordination, and/or other interventions.

Cultural Experiences of Arab American Caregivers Raising Children with Autism Spectrum Disorder

Research on families' experiences raising children with Autism Spectrum Disorder (ASD) is limited in minority ethnic and cultural groups, such as the Arab American community. Twenty Arab American caregivers raising children with ASD completed online questionnaires regarding their experiences with stigma and acculturation. Nine participants completed follow-up phone interviews. Perceived stigma fell in the low to moderate range. Acculturation related to social interactions indicated slightly greater assimilation compared to separation, and slightly greater integration over marginalization. During interviews, participants discussed the impact of disability stigma, distancing from their communities, and parent gender roles. By better understanding Arab American families raising children with ASD professionals can work towards improving clinical services for these families.

Disparities in Documented Diagnoses of Autism Spectrum Disorder Based on Demographic, Individual, and Service Factors

The objectives of our study were to (a) report how many children met an autism spectrum disorder (ASD) surveillance definition but had no clinical diagnosis of ASD in health or education records and (b) evaluate differences in demographic, individual, and service factors between children with and without a documented ASD diagnosis. ASD surveillance was conducted in selected areas of Arizona, Arkansas, Colorado, Georgia, Maryland, Minnesota, Missouri, New Jersey, North Carolina, Tennessee, and Wisconsin. Children were defined as having ASD if sufficient social and behavioral deficits and/or an ASD diagnosis were noted in health and/or education records. Among 4,498 children, 1,135 (25%) had ASD indicators without having an ASD diagnosis. Of those 1,135 children without a documented ASD diagnosis, 628 (55%) were not known to receive ASD services in public school. Factors associated with not having a clinical diagnosis of ASD were non-White race, no intellectual disability, older age at first developmental concern, older age at first developmental evaluation, special education eligibility other than ASD, and need for fewer supports. These results highlight the importance of reducing disparities in the diagnosis of children with ASD characteristics so that appropriate interventions can be promoted across communities. Autism Res 2020, 13: 464-473. © 2019 International Society for AutismResearch,Wiley Periodicals, Inc. LAY SUMMARY: Children who did not have a clinical diagnosis of autism spectrum disorder (ASD) documented in health or education records were more likely to be non-White and have fewer developmental problems than children with a clinical diagnosis of ASD. They were brought to the attention of healthcare providers at older ages and needed fewer supports than children with a clinical diagnosis of ASD. All children with ASD symptoms who meet diagnostic criteria should be given a clinical diagnosis so they can receive treatment specific to their needs.

Nonrapid eye movement sleep and risk for autism spectrum disorder in early development: A topographical electroencephalogram pilot study

OBJECTIVE

Autism spectrum disorder (ASD) is a pervasive neurodevelopmental disorder that emerges in the beginning years of life (12-48 months). Yet, an early diagnosis of ASD is challenging as it relies on the consistent presence of behavioral symptomatology, and thus, many children are diagnosed later in development, which prevents early interventions that could benefit cognitive and social outcomes. As a result, there is growing interest in detecting early brain markers of ASD, such as in the electroencephalogram (EEG) to elucidate divergence in early development. Here, we examine the EEG of nonrapid eye movement (NREM) sleep in the transition from infancy to toddlerhood, a period of rapid development and pronounced changes in early brain function. NREM features exhibit clear developmental trajectories, are related to social and cognitive development, and may be altered in neurodevelopmental disorders. Yet, spectral features of NREM sleep are poorly understood in infants/toddlers with or at high risk for ASD.

METHODS

The present pilot study is the first to examine NREM sleep in 13- to 30-month-olds with ASD in comparison with age-matched healthy controls (TD). EEG was recorded during a daytime nap with high-density array EEG.

RESULTS

We found topographically distinct decreased fast theta oscillations (5-7.25 Hz), decreased fast sigma (15-16 Hz), and increased beta oscillations (20-25 Hz) in ASD compared to TD.

CONCLUSION

These findings suggest a possible functional role of NREM sleep during this important developmental period and provide support for NREM sleep to be a potential early marker for ASD.

Screening Instruments for Developmental and Behavioral Concerns in Pediatric Hispanic Populations in the United States: A Systematic Literature Review

BACKGROUND

Racial and ethnic disparities in the identification of developmental and behavioral concerns in children are public health problems in the United States. Early identification of developmental delay using validated screening instruments provides a pathway to prevention and intervention in pediatric health care settings. However, the validity of Spanish-language screening instruments, used in clinical settings in the United States, has not been systematically examined.

OBJECTIVE

This study aims to review the literature of clinically administered developmental and behavioral instruments with Hispanic caregivers to investigate implementation variation due to language and cultural factors.

METHODS

A systematic literature review using PubMed and PsycINFO was conducted of articles published from January 1, 2006 to December 12, 2017. Abstract, full-text, and critical appraisal resulted in 11 studies that met criteria for inclusion.

RESULTS

Five different instruments were used to screen Hispanic or Spanish-speaking caregivers of children younger than 6 years. None of the instruments established validity and reliability apart from Spanish translation. Two studies identified differences in screening results with Spanish-speaking caregivers due to language and 6 described cultural differences that impacted screening implementation. Two studies reported differential item functioning in Spanish-translated instruments.

CONCLUSIONS

Language and cultural considerations are critical to the administration of valid and reliable screening in pediatric health care settings. Available developmental and behavioral Spanish-language-screening instruments function differently because of both language and culture, suggesting the tools are not as psychometrically valid when administered to Spanish-speaking families. Validation of translated screening instruments is essential to eliminate the possibility of detection bias or misidentification of developmental risk, improving early access to clinical services for Hispanic and Spanish-speaking families.

Increasing Access to Autism Spectrum Disorder Diagnostic Consultation in Rural and Underserved Communities: Streamlined Evaluation Within Primary Care

OBJECTIVE

Preliminary feasibility and clinical utility research has demonstrated that implementation of a streamlined diagnostic model embedded within primary care (PC) clinics promotes early identification of young children with autism spectrum disorder (ASD). Use of this model results in dramatically reduced waits for diagnostic consultation, high levels of family/provider satisfaction, and reductions in referrals to overtaxed tertiary diagnostic centers. The current study extends this work by providing data before/after implementation of a streamlined model across a diverse range of PC clinics that provide health care to rural and underserved communities.

METHODS

The streamlined assessment involved record/history review, diagnostic interview, standard rating scales, and an interactive screening tool. Eighty children between the ages of 19 and 47 months were seen across 5 different clinics. Data were collected through chart review.

RESULTS

Implementation of streamlined model resulted in a significant decrease in latency to diagnostic conclusion from a mean of 144.7 to 49.9 days. Children were likely to experience a greater reduction in wait times if they were a PC patient versus a non-PC patient.

CONCLUSION

Results show significant reduction in wait times for ASD diagnostic decisions across both PC and non-PC patients. By reducing waits and identifying concerns more efficiently, we may increase the ability of families to access early intervention and support services.

Are school psychologists' special education eligibility decisions reliable and unbiased?: A multi-study experimental investigation

Nearly 50 years of research show persistent racial disproportionality in the identification of special education disabilities, but the underlying mechanisms for these disparities remain largely unexplored. Because ambiguous regulations defining disabilities may allow subjectivity and unlawful differential treatment (i.e., racial bias or discrimination) in the special education eligibility process, an important target of study is disparate treatment of students by race in evaluations required to determine eligibility. School psychologists have long been recognized as highly influential in this process and in schools' resultant decisions. We used a 3 × 2 mixed factorial experimental design in three studies with simulated case report data to measure the influence of race and assessment data on school psychologists' perceptions of students' eligibility for special education in cases centering on emotional disturbance, intellectual disability, or autism, respectively. Participants included 302 practicing school psychologists in three states across the three experiments. There was little evidence of racial disparity, but participants tended to render decisions unsupported by, and even contrary to, evaluation data. Implications for research, practice, and professional development are discussed.

Race/Ethnicity-Resolved Time Trends in United States ASD Prevalence Estimates from IDEA and ADDM

Race-specific time trends in Autism Spectrum Disorder prevalence are tracked among 3-5 year-olds and 8 year-olds identified by the U.S. Individuals with Disabilities Education Act (IDEA) and the Autism and Developmental Disabilities Monitoring (ADDM) Network, respectively. White ASD prevalence historically has been higher than other racial groups but plateaued for IDEA birth cohorts from ~ 2004 to 2007 before resuming its increase. Black and Hispanic IDEA prevalence increased continuously and caught up to whites by birth year ~ 2008 and ~ 2013, respectively, with black prevalence subsequently exceeding white prevalence in the majority of states. Plateaus in white prevalence occurred in some ADDM states for birth years 2002-2006, but IDEA trends suggest prevalence will increase across all racial groups in ADDM's birth year 2008 report.

A Randomized Waitlist-Control Group Study of a Culturally Tailored Parent Education Intervention for Latino Parents of Children with ASD

This two-site randomized waitlist-control study (n = 96 mother-child dyads) examined the efficacy of a psychoeducation program as compared to usual care to empower Latina mothers and improve their confidence in and use of evidence-based practices (EBPs) for their children with ASD. A secondary aim was to improve child outcomes. Compared to control group, we found significant positive changes in the treatment group in maternal confidence of and frequency in use of EBPs, child social communication and the number of EB services the child received. We found no significant differences for the treatment group in family empowerment or in child challenging behaviors. This RCT presents evidence of an efficacious intervention for Latino children with ASD and their mothers in California and Illinois.

Circuits for social learning: A unified model and application to Autism Spectrum Disorder

Early life social experiences shape neural pathways in infants to develop lifelong social skills. This review presents the first unified circuit-based model of social learning that can be applied to early life social development, drawing together unique human developmental milestones, sensitive learning periods, and behavioral and neural scaffolds. Circuit domains for social learning are identified governing Activation, Integration, Discrimination, Response and Reward (AIDRR) to sculpt and drive human social learning. This unified model can be used to identify social delays earlier in development. We propose social impairments observed in Autism Spectrum Disorder are underpinned by early mistimed sensitive periods in brain development and alterations in amygdala development to disrupt the AIDRR circuits. This model directs how interventions can target neural circuits for social development and be applied early in life. To illustrate, the role of oxytocin and its use as an intervention is explored. The AIDRR model shifts focus away from delivering broad treatments based only on diagnostic classifications, to specifying and targeting the relevant circuits, at the right time of development, to optimize social learning.

Racial and Ethnic Disparities in Autism-Related Health and Educational Services

OBJECTIVE

The objective of this study is to measure racial and ethnic disparities in autism-related services among U.S. children with parent-reported autism spectrum disorder (ASD).

METHODS

Using the 2011 Survey of Pathways to Diagnosis and Services, we analyzed parent-reported data on 1420 children with current ASD in the nationally representative sample. An estimation method consistent with the Institute of Medicine's definition of health care disparities is used to measure racial and ethnic disparities.

RESULTS

The findings revealed Latino-white disparities in the percentage of children currently using school-based occupational and physical therapy and Latino-white and "other race"-white disparities in the percentage of children using physical therapy outside of school. There were no statistically significant black-white disparities. Instead, the study found that the percentage of black children with ASD receiving school-based services was 8 points higher than that of white children (p < 0.04). Factors unrelated to the need for autism services were largely unassociated with the receipt of services.

CONCLUSION

The findings provide a partial baseline and identify a need for further examination of the source of existing disparities and the lack of disparities found for specific services and minority groups.

Service use, unmet needs, and barriers to services among adolescents and young adults with autism spectrum disorder in Poland

Background

Despite a growing number of adolescents and adults diagnosed with autism spectrum disorder (ASD), little is known about service needs and barriers to services in this population. Existing research shows that youth with ASD are more underserved as they approach final years of their high school education and that adequate services for individuals with ASD after transition to adulthood are even scarcer. However, few studies have directly compared differences in service availability between adolescents and adults with ASD, and even fewer studies are published on service use outside Anglo-Saxon countries. The purpose of the present study was to examine service access, perceived barriers, and unmet needs, as reported by parents of adolescents and young adults with ASD in Poland.

Methods

The study used a subsample of parents of young people with ASD (aged 12–38 years; N = 311) from the Polish Autism Survey – a survey covering different areas of functioning of people with ASD in Poland, based on a convenience sample. Responding parents were recruited via different service providers, social media, and press, and completed a survey using a web platform or a paper-and-pencil questionnaire.

Results

As expected, adults used services less often than adolescents, with 80.1% of adolescents and 61.1% of adults with ASD using services in the previous 12 months. Mental health services were among the most used and the most needed services, followed by educational services, while needs for sensory/motor services remained largely unmet. Young people with a coexisting intellectual disability used more services than those without it. Non-governmental organizations, private clinics, and schools were the most common service providers. Parents indicated that most of young people with ASD had unmet service needs for services (93.5%) and faced barriers to access them (82.7%). Low-income families and those living outside large cities were at the highest risk of facing barriers to service access.

Conclusions

The results confirm still a thin body of evidence from different countries suggesting that adolescents and adults with ASD were both largely underserved populations. Policy-makers should address economic, regional, and age-related inequities in access to services for individuals with ASD.

Parent Perceptions of Community Autism Spectrum Disorder Stigma: Measure Validation and Associations in a Multi-site Sample

In this study we developed a brief, English/Spanish bilingual parent-reported scale of perceived community autism spectrum disorder (ASD) stigma and tested it in a multi-site sample of Latino and non-Latino white parents of children with ASD. Confirmatory factor analysis of the scale supported a single factor solution with 8 items showing good internal consistency. Regression modeling suggested that stigma score was associated with unmet ASD care needs but not therapy hours or therapy types. Child public insurance, parent nativity, number of children with ASD in the household, parent-reported ASD severity, and family structure, were associated with higher stigma score. The scale and the scale's associations with service use may be useful to those attempting to measure or reduce ASD stigma.

Caregiver Voices: Cross-Cultural Input on Improving Access to Autism Services

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.

Healthcare access and services use among US children with autism spectrum disorder

This study aimed to determine associations of healthcare access problems with services use among US children with autism spectrum disorder. We analyzed 2011-2014 National Health Interview Survey data on 651 children with autism spectrum disorder aged 2-17 years. There were three measures of healthcare access problems: (1) delays accessing healthcare, (2) difficulty affording healthcare, and (3) trouble finding a primary care provider. There were five service use measures: (1) ⩾4 office visits, (2) ⩾1 well-child visit, (3) flu vaccine, (4) prescription medication, and (5) ⩾1 emergency department visit. Multivariable regression models estimated associations of ⩾1 healthcare access problem with each service use variable and effect modification by socioeconomic status and race and ethnicity. Twenty-nine percent of children with autism spectrum disorder had ⩾1 healthcare access problem. Having ⩾1 healthcare access problem was associated with lower adjusted odds of ⩾1 well-child visit or prescription medication use but higher adjusted odds of ⩾4 office visits or ⩾1 emergency department visit. No significant association was found for flu vaccine. Associations of healthcare access problems with emergency department use were most pronounced for higher socioeconomic status and White, non-Hispanic subgroups. Intervention, such as insurance expansion, is needed to improve healthcare access for children with autism spectrum disorder.

Early Identification of ASD Through Telemedicine: Potential Value for Underserved Populations

Increasing access to diagnostic services is crucial for identifying ASD in young children. We therefore evaluated a telemedicine assessment procedure. First, we compared telediagnostic accuracy to blinded gold-standard evaluations (n = 20). ASD cases identified via telemedicine were confirmed by in-person evaluation. However, 20% of children diagnosed with ASD in-person were not diagnosed via telemedicine. Second, we evaluated telediagnostic feasibility and acceptability in a rural catchment. Children (n = 45) and caregivers completed the telemedicine procedure and provided feedback. Families indicated high levels of satisfaction. Remote diagnostic clinicians diagnosed 62% of children with ASD, but did not feel capable of ruling-in or out ASD in 13% of cases. Findings support preliminary feasibility, accuracy, and clinical utility of telemedicine-based assessment of ASD for young children.

Factors Influencing Low Prevalence of Neurodevelopmental Disabilities Among US Hispanic/Latino Children

OBJECTIVES

Hispanic/Latino (H/L) children have lower prevalence of neurodevelopmental disabilities (NDD) than other groups. The explanations for this are complex, but may be related to nativity, language barriers, and lack of access to and utilization of healthcare. Previous research focused on how these factors affect children with NDD, but little research has jointly examined whether these factors predict NDD. This study examines whether social and environmental factors explain low prevalence of NDD in this population.

METHODS

This study uses nationally representative Integrated Public Use Microdata Series National Health Interview Survey data (N = 200,622) and multivariate logistic regression analysis to compare NDD prevalence in white and H/L children (average age of 10.2), and examines whether nativity, healthcare access, healthcare utilization, and language barriers explain this disability disparity.

RESULTS

Findings reveal that the H/L NDD disparity is not explained by differences in access to or utilization of healthcare, or as a result of language differences that may create barriers to NDD diagnosis. While H/L children whose sampled adult was born in the USA have lower rates of NDD than whites, H/Ls whose sampled adult were not born in the USA have even lower probability of NDD than H/Ls who were born in the USA.

CONCLUSIONS

These findings may be a result of cultural differences in knowledge or understanding of what constitutes a disability or the result of differential treatment within the healthcare system among H/Ls. The findings underscore the importance of accessible and culturally appropriate health and clinical care interventions among H/L communities.

Treatment Utilization Trajectories among Children with Autism Spectrum Disorder: Differences by Race-Ethnicity and Neighborhood

Health coverage of early intensive behavioral intervention (EIBI) for children with autism spectrum disorder is expanding. Yet there is no longitudinal research on patterns of or inequities in utilization of EIBI. We integrated state administrative records with Medicaid and Census data for children enrolled in an EIBI Medicaid waiver (N = 730) to identify and describe the type and prevalence of treatment utilization trajectories, and to examine the association between trajectory types and (a) child race-ethnicity and (b) neighborhood racial composition, poverty, affluence, and urbanicity. We identified four utilization trajectories (Low, Low-Moderate, Moderate, and High users). Race-ethnicity and neighborhood affluence were associated with trajectory membership. As coverage expands, policy makers should consider strategies to improve overall treatment utilization and enhance equity.

Child-rearing routines among Mexican-heritage children with autism spectrum disorder

This study examined the daily routines and activities of Mexican-heritage mothers and their children with autism spectrum disorder. Experienced sampling methods were used to capture families' current daily routines and activities, how parents valued those activities, and whether the activity was part of the child's autism spectrum disorder intervention. A total of 32 mothers were texted five times per day over five consecutive days for a total of 721 observations. Mothers frequently engaged in Self-Care (e.g. showering), General Caregiving (e.g. cooking), and House Chores (e.g. laundry). Children engaged in activities in which interventions could easily be integrated (e.g. Academics, Self-Care, and Playing with Others). Families spent less than one-third (26.1%) of their activities participating in interventions. Mothers and children jointly spent time in General Caregiving, Playing with Others, and Using Electronics. Practitioners should focus on integrating evidence-based interventions into daily joint routine activities.

Predictors of Caregivers' Satisfaction with the Management of Children with Autism Spectrum Disorder: A Study at Multiple Levels of Health Care

Background: Caregivers are the initial gatekeepers in the health care management of children with autism spectrum disorder (ASD). Methods: This cross-sectional study aimed to determine the factors associated with caregivers’ satisfaction with different levels of health care services in managing children with ASD in Kelantan. The satisfaction scores of 227 main caregivers of confirmed ASD children were assessed with a modified Parent Satisfaction Scale (PSS) questionnaire. Results: The analysis showed that caregivers who waited longer for a doctor’s consultation in primary care had a reduced PSS score, whereas caregivers who were satisfied with the waiting time in primary care had higher PSS scores. At the secondary care level, caregivers who possessed at least a diploma had reduced PSS scores, whereas caregivers who were satisfied with both doctors’ consultation times and occupational therapy appointments had higher PSS scores. At the tertiary care level, caregivers with an underlying medical problem and who had children undergoing occupational therapy for two months or more had reduced PSS scores. Nevertheless, the analysis showed that caregivers who were concerned with their children’s sleeping problems, who had been informed about parental support, who were satisfied with speech and occupational therapy appointments, who were satisfied with waiting times at tertiary care clinics, and who were satisfied with their doctor’s knowledge and experience had higher PSS scores. Conclusions: This study elucidated the importance of understanding caregivers’ satisfaction in attaining care for their ASD children and highlighted the need to promote factors that would increase caregivers’ satisfaction with current ASD services.

Autism Disparities: A Systematic Review and Meta-Ethnography of Qualitative Research

Racial, ethnic, and socioeconomic disparities associated with autism spectrum disorder (ASD) are evident across many service domains including access to early assessment, diagnosis, and therapeutic interventions. To better understand the complex social and structural factors contributing to these disparities, this article offers a systematic review of peer-reviewed qualitative research conducted from 2010 to 2016 in the United States that investigates autism disparities experienced by marginalized communities. Based on these criteria, we identified 24 qualitative research studies and conducted an analysis using meta-ethnography and an intersectional interpretive lens. We identified three interdependent themes contributing to autism disparities, including familial, cultural, and structural barriers. Omissions in the literature were also evident, including a lack of research on underserved adults with ASD and the gendered inequities of caregiving. We discuss the implications of our findings and offer new questions that take an intersectional approach using qualitative research to investigate autism disparities.

Prevalence, Health and Resource Utilization, and Unmet Healthcare Needs of Native Hawaiian and Pacific Islander Children With Developmental Disabilities

Little is known about health limitations and service utilization among the Native Hawaiian and Pacific Islander (NHPI) children with developmental disabilities (DDs) due to limited data. Our study examined the prevalence of DDs, health limitations, services used, and the unmet needs of NHPI children aged 3 to 17 years using cross-sectional data from the 2014 NHPI National Health Interview Survey. Results showed that prevalence of DDs among NHPI children was lower than American children of other races. DDs were negatively associated with health and functioning of NHPI children. There is a need to promote understanding of DDs among NHPI families and to inform public policy makers to identify appropriate intervention services for NHPI children.

Parent and Provider Perspectives on the Diagnosis and Management of Autism in a Chinese Immigrant Population

OBJECTIVE

Minority families experience disparities in the diagnosis and management of autism spectrum disorder (hereafter "autism"). To date, the experiences of Chinese immigrant families in the United States have not been explored. Utilizing parent and provider perspectives, this research sought to identify barriers and facilitators to the diagnosis and management of autism among Chinese immigrant children.

METHODS

We conducted semistructured qualitative interviews with 16 parents of Chinese children diagnosed with autism and 16 providers who assist in the diagnosis and management of autism. Participant characteristics were analyzed utilizing descriptive statistics. Interviews were audiorecorded, transcribed, translated, and independently coded by 2 researchers until consensus was reached. Coded data were analyzed using a modified grounded therapy approach.

RESULTS

Parents and providers both identified cultural beliefs as an influence on the understanding and acceptance of autism as a diagnosis. There was a high degree of alignment in themes related to barriers to health care access and parent-provider communication. Recommendations to improve the system of care include (1) supporting communication, (2) cultural sensitivity, and (3) care coordination programming.

CONCLUSION

Findings reinforce that diagnosis and treatment of autism should take into account culturally specific beliefs about child developmental norms and should address systems-, provider-, and family-level barriers.

Loss in services precedes high school exit for teens with autism spectrum disorder: A longitudinal study

The present longitudinal study investigated changes in service receipt and unmet service needs spanning 14 years before and after high school exit in a large community-based sample of individuals with autism spectrum disorder (ASD) (n = 204), of whom 59% had co-occurring intellectual disability (ID). Using multilevel models, potential discontinuity of service patterns at the point of high school exit was examined, as well as the rate of change in services received and needed during the high school years and into the post-high school period. Differences between those with and without ID were probed. Study findings indicated that overall, sample members experienced a reduction in receipt of services during high school, particularly for those without co-occurring ID. After high school exit, sample members experienced a decline in services received; for those without ID, there was a continuous rate of loss of services after leaving high school but for those with ID, there was a sharp decline in services received. Unmet service needs increased right after high school exit for both those with and without ID. These patterns reflect loss of entitlement for services that accompanies high school exit, and the limited availability of adult services for individuals with ASD. This study documented not only the post-high school service cliff that has been the subject of much concern, but also that the loss of services begins long before high school exit and that subgroups of the population with ASD are particularly vulnerable. Autism Res 2019, 12: 911-921. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: In this research, we studied changes in the number of services received before and after high school exit in a large sample of individuals with autism spectrum disorder (ASD). With each passing year during high school, individuals with ASD received fewer services. At the time of high school exit, there was a sharp drop in the number of services received, particularly for those with co-occurring intellectual disability. This study found not only that there is a post-high school service cliff, but also that the loss of services begins long before high school exit.

Using latent class analysis to identify treatment-use subgroups among parents of children with autism spectrum disorder

Among parents of 2,582 children (ages 4-17 years old) with autism spectrum disorder (ASD), we used latent class analysis to identify subgroups and profiles of treatment users and included annual household income in the specification of the models, then described characteristics of each subgroup. Based on three indicators of fit (Akaike's Information Criterion, Bayesian Information Criterion, and Lo-Mendell-Rubin), six latent classes of treatment users emerged. Subgroups included users of: (a) mostly private and school speech and occupational therapies; (b) nearly all treatment types; (c) mostly speech and occupational therapies, plus intensive behavioral and "other" treatments, but little medication use; (d) private therapies almost exclusively; (e) primarily psychotropic medications; and (f) mostly school-based therapies. Income significantly predicted class differences for all but one latent class. Probabilities of families' lifetime use of nine treatment types varied depending on latent classification. Proportions of families reporting having observed children's developmental regression were largest in those with the highest overall treatment use, and these children also had the lowest cognitive and adaptive-functioning scores and the highest ASD symptom scores. Understanding patterns of treatment use among families of children with ASD is an important first step in enhancing treatment-related selection and implementation. Autism Research 2019, 12: 843-854. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We identified six different groups of treatment users to help explain patterns in treatment implementation among parents of children and adolescents with autism. These included families who used: (a) mostly used private and school speech and occupational therapies; (b) nearly all treatment types (private and school therapies, intensive behavioral, biomedical, psychotropic medications, and other treatments); (c) mostly speech and occupational therapies, plus intensive behavioral and "other" treatments, but little medication use; (d) private therapies almost exclusively; (e) primarily psychotropic medications; and (f) mostly school-based therapies.

Time-Lag Between Diagnosis of Autism Spectrum Disorder and Onset of Publicly-Funded Early Intensive Behavioral Intervention: Do Race-Ethnicity and Neighborhood Matter?

Health coverage of early intensive behavioral intervention (EIBI) for children with autism spectrum disorder (ASD) is rapidly expanding across the United States. Yet we know little about the time-lag between diagnosis and treatment onset. We integrated administrative, Medicaid claims, and Census data for children in an EIBI Medicaid waiver (n = 473) to examine the relationship between time-lag and (a) child race-ethnicity and (b) neighborhood racial composition, poverty, affluence, and urbanicity. We explored whether the relationship between child race-ethnicity and time-lag varies by neighborhood characteristics. Average time-lag between diagnosis and treatment onset was nearly 3 years. Child race-ethnicity and neighborhood characteristics did not predict time-lag. Reducing time-lag is critical to ensuring that children with ASD receive treatment as early as possible.

Excess Folic Acid Supplementation Before and During Pregnancy and Lactation Activates Fos Gene Expression and Alters Behaviors in Male Mouse Offspring

Periconceptional folic acid (FA) supplementation is recommended to prevent neural tube defects and other birth defects. After 20 years mandate food fortification with FA, serum concentration of folate and unmetabolized FA increased significantly in the North American population. But whether excess FA intake impairs neurodevelopment and behavior is still controversial. Here, we treated mice with approximately 2.5-fold (moderate dose of FA, MFA) or 10-fold (high dose of FA, HFA) the dietary requirement of FA 1 week before mating and throughout pregnancy and lactation, and examined behaviors in adult male offspring using open field test, three-chamber sociability and social novelty test, elevated plus maze, rotarod and Morris water maze. We found that early life MFA supplementation increased long-term body weight gain in adults, elevated anxiety-like behavior, and impaired social preference, motor learning and spatial learning ability without modifying motor ability and spatial memory. In contrast, HFA supplementation only induced mild behavioral abnormality. RNA sequencing revealed that FA supplementation altered the expression of brain genes at weaning, among which Fos and related genes were significantly up-regulated in MFA mice compared with control and HFA mice. Quantitative real time-PCR (qRT-PCR) and western blots confirmed the increase of these genes. Our results suggested that FA supplementation during early life stage affected gene expression in weaning mice, and exhibited long-term impairments in adult behaviors in a dose-sensitive manner.

Language Barriers Impact Access to Services for Children with Autism Spectrum Disorders

Racial and ethnic disparities in accessing health care have been described in children with autism spectrum disorder (ASD). In a retrospective chart review of 152 children with ASD, children of parents whose primary language was English were significantly more likely to have both social skills and communication goals within their individualized education plan (IEP) compared to children of parents whose primary language was not English. Additionally, children of primary English speakers received significantly more hours of direct services from their state disability program. After controlling for demographic covariates, findings suggest that language barriers may negatively affect parents' abilities to access health care services for their child with ASD. Acculturation factors must therefore be considered when analyzing disparities in autism.

Impact of multiple co-occurring emotional and behavioural conditions on children with autism and their families

BACKGROUND

Comorbid conditions are very common in children and adults with autism spectrum disorder (ASD) and can affect school performance, adaptive skills and peer relationships. Comorbid conditions place strain on the family as well as the individual with ASD. This project aimed to determine the affect of comorbid conditions over and above child and family characteristics.

METHODS

The present authors examined 3,055 cases of children with ASD who had varying numbers of comorbid conditions (i.e., ADHD, depression, anxiety or behaviour problems).

RESULTS

Multiple comorbid conditions did have a unique impact on difficulties accessing services. A greater number of comorbid conditions impacted daily activity participation, but not a family's receipt of mental health care or respite, work changes or number of weekly hours dedicated to caring for a child with ASD.

CONCLUSIONS

Families, practitioners, paraprofessionals and educators of children with autism should address comorbid conditions to ensure both child and family well-being.

Ambient ozone and fine particulate matter exposures and autism spectrum disorder in metropolitan Cincinnati, Ohio

BACKGROUND

Epidemiological studies report fairly consistent associations between various air pollution metrics and autism spectrum disorder (ASD), with some elevated risks reported for different prenatal and postnatal periods.

OBJECTIVES

To examine associations between ASD and ambient fine particulate matter (PM_2.5) and ozone concentrations during the prenatal period through the second year of life in a case-control study.

METHODS

ASD cases (n = 428) diagnosed at Cincinnati Children's Hospital Medical Center were frequency matched (15:1) to 6420 controls from Ohio birth records. We assigned daily PM_2.5 and ozone estimates for 2005-2012 from US EPA's Fused Air Quality Surface Using Downscaling model to each participant for each day based on the mother's census tract of residence at birth. We calculated adjusted odds ratios (aORs) using logistic regression across continuous and categorical exposure window averages (trimesters, first and second postnatal years, and cumulative measure), adjusting for maternal- and birth-related confounders, both air pollutants, and multiple temporal exposure windows.

RESULTS

We detected elevated aORs for PM_2.5 during the 2nd trimester, 1st year of life, and a cumulative period from pregnancy through the 2nd year (aOR ranges across categories: 1.41-1.44, 1.54-1.84, and 1.41-1.52 respectively), and for ozone in the 2nd year of life (aOR range across categories: 1.29-1.42). Per each change in IQR, we observed elevated aORs for ozone in the 3rd trimester, 1st and 2nd years of life, and the cumulative period (aOR range: 1.19-1.27) and for PM_2.5 in the 2nd trimester, 1st year of life, and the cumulative period (aOR range: 1.11-1.17).

DISCUSSION

We saw limited evidence of linear exposure-response relationships for ASD with increasing air pollution, but the elevated aORs detected for PM_2.5 in upper exposure categories and per IQR unit increases were similar in magnitude to those reported in previous studies, especially for postnatal exposures.

Disparities Based on Race, Ethnicity, and Socioeconomic Status Over the Transition to Adulthood Among Adolescents and Young Adults on the Autism Spectrum: a Systematic Review

PURPOSE OF REVIEW

Few studies have examined disparities in autism services and functional outcomes over the life course. Transition to adulthood is an especially important developmental period, as it sets up trajectories of adult functioning. This systematic review summarizes patterns of service use and transition outcomes according to race, ethnicity, and socioeconomic characteristics over the transition to adulthood.

RECENT FINDINGS

Forty studies were included. Low-income and racial/ethnic minority youth on the autism spectrum were less likely to participate in transition planning meetings, enroll in postsecondary education, find competitive employment after high school, live independently, participate in social activities, and receive health care transition services than their White and higher income peers on the autism spectrum. Racial/ethnic minority and low-income youth on the autism spectrum were more likely to be disconnected from educational, occupational, and social activities upon entering adulthood. Future research should explore the mechanisms underlying these disparities as a first step to addressing them.

Assessment of racial and ethnic bias in autism spectrum disorder prevalence estimates from a US surveillance system

This study assessed potential under-ascertainment of autism spectrum disorder due to missing administrative information for Hispanic and non-Hispanic Black children within the Autism and Developmental Disabilities Monitoring Network. We analyzed data from two Network sites (Colorado and Wisconsin) for surveillance years 2012 and 2014 to determine whether children excluded from autism spectrum disorder prevalence estimates due to missing residency and other information differed from those included by race and ethnicity. We used multiple approaches to impute missing information to evaluate impacts on racial and ethnic disparities in autism spectrum disorder prevalence. Compared with confirmed autism spectrum disorder cases, those excluded due to missing residency were more than twice as likely to be Hispanic (19% vs 44%; p < 0.002), yet the number of cases excluded due to missing residency information was too small to account for prevalence differences. Confirmation of autism spectrum disorder case status was more likely for children with relevant health records than for those with school records only. Moreover, relevant health records were more likely to be missing for Black and Hispanic children than for White children. Observed disparities in autism spectrum disorder prevalence were not accounted for by missing demographic data, but may reflect disparities in healthcare access for developmental evaluations.

Modifying a general social-emotional measure for early autism screening

Objective: Broadband social-emotional screening tools are designed to evaluate a child's social development and interactions. Such tools are expected to have reasonable sensitivity for identifying children at risk for autism spectrum disorder (ASD) but would also likely over-estimate risk for ASD since other conditions can also affect social development. In this study, a subset of ASD items from one general social-emotional screening measure, the Ages & Stages Questionnaires: Social Emotional, 2nd edition, was analyzed to determine if use of an ASD subscale might improve prediction of ASD risk for young children. Methods: The ASD subscale was used with 60 families who had a child referred for an ASD evaluation. Social-emotional screening and ASD screening results were compared with the subsequent results from gold-standard diagnostic testing for ASD at a regional autism center, using contingency matrices. Results: As expected, the social-emotional screening tool identified nearly all of the children in the high-risk clinical sample. Use of the ASD subscale increased specificity for ASD (from 4% to 52%) and demonstrated correct prediction of ASD diagnosis in 70% of ASD cases. Conclusions: These preliminary results suggest that using a subset of ASD-specific items on a social-emotional screening tool can increase the tool's specificity for ASD, by isolating ASD-specific concerns.

Anglo-Latino differences in parental concerns and service inequities for children at risk of autism spectrum disorder

In an evaluation of Anglo and Latina mothers and their children at risk of autism, this study compared mother-reported child behavioral concerns to staff-observed symptoms of autism. Within Latina mothers, the impact of primary language (English/Spanish), mothers' education, and child age on ratings of developmental concerns was examined. Participants were 218 mothers (Anglo = 85; Latina = 133) of children referred to a no-cost autism screening clinic. Mothers reported on behavioral concerns, autism symptomology, and services received; children were administered the Autism Diagnostic Observation Schedule by certified staff. Results revealed that Anglo and Latino children did not differ by autism symptoms or classification. However, Anglo mothers reported significantly more concerns than Latina mothers. Within the Latina group, analyses revealed significant interaction effects of language and child age; Spanish-speaking mothers of preschoolers endorsed fewer concerns, while Spanish-speaking mothers of school-aged children endorsed more concerns. Despite these reports, Anglo children with a classification of autism spectrum disorder were receiving significantly more services than Latino children with autism spectrum disorder, suggesting early beginnings of a service divide as well as the need for improved parent education on child development and advocacy for Latino families.

Geographic Disparities in Treatment for Children with Autism Spectrum Disorder

OBJECTIVE

Geographic differences may provide insight into what factors influence the likelihood that a child is diagnosed with autism spectrum disorder (ASD) in the United States; yet, there have been few nationally representative surveys that have explored this topic. The current study expands the limited literature by analyzing regional differences in ASD prevalence, service utilization, and the presence of unmet needs within a nationally representative sample of children.

METHODS

Data were drawn from the 2014-2016 National Health Interview Survey (NHIS), a nationally representative household survey of the noninstitutionalized US population. Children 3 to 17 years of age were included in the analytic sample. Prevalence estimates accounted for the complex survey design of the NHIS, and differences between geographic regions were compared using logistic/linear regressions with and without adjustment for child/family characteristics.

RESULTS

The prevalence of ASD was highest in the Northeast (3.0%), followed by the Midwest (2.4%), South (2.4%), and West (2.3%). A significant difference was found between the Northeast and West (P < .05); however, after accounting for child and family characteristics, this difference was no longer significant. Children with ASD in the Northeast were the most likely to have seen a specialist in the past year. Approximately 1 in 8 children with ASD experienced at least 1 unmet need, but there were no differences found by geographic region.

CONCLUSIONS

Although differences in prevalence were not significant after adjustment, service utilization differences remained. It appears that children with ASD in the Northeast utilize the greatest number of specialty services when compared to children with ASD from other parts of the country.

Race influences parent report of concerns about symptoms of autism spectrum disorder

Racial differences in parent report of concerns about their child's development to healthcare providers may contribute to delayed autism spectrum disorder diagnoses in Black children. We tested the hypotheses that compared to White parents, Black parents of children with autism spectrum disorder would report fewer concerns about autism symptoms and would be more likely to report concerns about disruptive behaviors. A sample of 18- to 40-month-old toddlers ( N = 174) with autism spectrum disorder and their parent participated. After screening positive for autism spectrum disorder risk, but prior to a diagnostic evaluation, parents completed free-response questions soliciting concerns about their child's development. Parent responses were coded for the presence or the absence of 10 possible concerns, which were grouped into autism concerns (e.g. social and restricted and repetitive behavior concerns) or non-autism concerns (e.g. general developmental and disruptive behavior concerns). Compared to White parents, Black parents reported significantly fewer autism concerns and fewer social and restricted and repetitive behavior concerns. However, Black parents did not report significantly fewer non-autism concerns. Race did not influence parent report of disruptive behavior concerns. Lower reporting of autism concerns by Black parents may impact providers' abilities to identify children who need further screening or evaluation.

A Video Parent-Training Program for Families of Children with Autism Spectrum Disorder in Albania

BACKGROUND

Behavioral intervention with parent participation is effective in reducing symptoms of Autism Spectrum Disorder (ASD), but access to intervention is limited. The current study explored whether a video-enriched parent-training program would (a) be comprehensible and acceptable to parents in the Republic of Albania, (b) increase parental knowledge of behavioral strategies and (c) increase parental self-efficacy.

METHODS

Twenty-nine parents of children with ASD aged 18-70 months completed the Early Intervention Parenting Self-Efficacy Scale (EIPSES, Guimond, Wilcox, & Lamorey, 2008) and a quiz to assess their knowledge of behavioral strategies. Parents in the Treatment Group then received access to a parent-training (PT) program on evidence-based teaching and behavior management techniques. The program was based on empirical research, but considered Albanian cultural norms and included topics Albanian parents requested. Parents in the Treatment Group rated the program using the Treatment Evaluation Inventory Short Form (TEI-SF; Kelley, Heffer, Gresham, & Elliott, 1989). Change in parents' quiz scores and EIPSES ratings from baseline to post-treatment were compared by group.

RESULTS

Parents rated this video training program as comprehensible and valuable. The program modestly increased aspects of self-efficacy as well as parents' knowledge of effective teaching strategies.

CONCLUSION

Remote PT may be useful in low-resource settings to help parents develop techniques for teaching skills and forestalling problem behavior in children with ASD. Additional research, with a larger sample size, that observes the effect of the program on child behavior is warranted.

Using Geospatial Analysis to Determine Access Gaps Among Children with Special Healthcare Needs

Purpose: To examine geospatial gaps in identification and evaluation of children with special healthcare needs (CSHCN) within public child development centers (CDCs).

Methods: A descriptive geospatial design was used to visually depict service gaps, proximity, and clustering of area-level sociodemographic attributes of Virginia counties, and patient-level data within each CDC.

Results: Geospatial analysis shows population density of uninsured children against CDC resources. Data visualization facilitates policy advocacy based on the identification of care and screening gaps for CSHCN.

Conclusion: This project illustrates the collaborative potential between researchers and Health Department members to identify gaps in access to care.
