Abstract

This study investigates whether sociodemographic factors are associated with utilization of intervention services for children with autism spectrum disorder (ASD) enrolled in the Childhood Autism Risks from Genetics and the Environment Study. Maternal ethnicity, insurance status, and education for 696 families of children with ASD were available. Children of Black mothers entered intervention earlier compared to White mothers (2 vs. 2.6 years; p = 0.001). Having public insurance was associated with receiving <15 h/week of individual services, while having a Bachelor degree was associated with receiving <15 h/week of classroom-based services. These differences suggest that SES may be a factor in utilization of services. Efforts should be made to ensure that interventions offered are culturally and linguistically accessible.

Introduction
Autism spectrum disorder (ASD) is a developmental dis-
order that is reliably diagnosed in early childhood. ASD
is characterized by communication problems, social inter-
action impairments, and restricted, repetitive patterns of
behavior and interests (American Psychiatric Association
2013). In the past 10 years, ASD has become a growing
public health topic as the prevalence of children with ASD
has increased from 1 in 150 in 2000 to 1 in 68 (Centers for
Disease Control and Prevention 2014) just 10 years later.
ASD has a heterogeneous etiology, and current research
has not yet identied a specic biological treatment for
the core symptoms of ASD. At present, the evidence-based
treatments for core ASD symptoms in young children sup-
ported by research are early intensive behavioral interven-
tion (EIBI) (Remington et al. 2007) programs that are based
on the principles of Applied Behavior Analysis (ABA), such
as Discrete Trial Teaching (Smith 2001), Pivotal Response
Treatment (Smith and Iadarola 2015), the Early Start Den-
ver Model (Dawson et al. 2010; Estes et al. 2015), and oth-
ers (Schreibman and Stahmer 2014).
Children with ASD who are enrolled earlier in intensive
early interventions have better outcomes, which include
improved daily living and cognitive skills (Peters-Scheffer et
al. 2011; Perry et al. 2011; Dawson et al. 2010). With such
promising data to support the effectiveness of early interven-
tion services, it is troubling that an estimated 9 in 10 children
with ASD are not fully utilizing behavioral health services
even with the existence of the Individuals with Disabilities
Education Act (IDEA) (Ruble et al. 2005). IDEA mandates
the provision of intervention services to children with disabil-
ities, including both general interventions, such as speech and
occupational therapy, as well as autism-specic therapies,
such as EIBI and emerging interventions such as Naturalistic

... In addition to race and ethnicity, socioeconomic factors (which include parent education, family income, and insurance type) have been identified as contributors to disparities, including access to, knowledge about, and use of services (Nguyen et al., 2016;Smith et al., 2020;Thomas et al., 2007). Willicutt's (2012) meta-analysis indicated that several studies found low SES to be associated with higher likelihood of ADHD identification, though other included studies suggested no socioeconomic differences. ...
... Almost 30% of studies in our review did not report anything about participants' SES. There are quite possibly differences not only in access to services but also to delays in identification, and lower service acceptability, related to SES (Nguyen et al., 2016;Smith et al., 2020), but this is impossible to ascertain when SES is often not reported in published studies (Cénat et al., 2022). Also, how SES indicators are selected and/or reported was quite varied in our review, creating difficulty in generalizability or even comparisons. ...

Underrepresentation of socioeconomically, culturally, and/or linguistically diverse (SCLD) children with neurodevelopmental disorders (NDD) and their families has become a focal point for researchers. This systematic review aimed to identify researchers’ strategies for recruiting and retaining SCLD families of children with NDD, published between 1993 and 2018. One hundred twenty-six articles were included, and study samples were categorized as “High SCLD” and “Low SCLD”. Chi-square tests of independence were used to determine associations between sample composition (i.e., High/Low SCLD sample) and study characteristics reported. Significant associations were found between sample composition and studies that explicitly stated intention to recruit SCLD families, χ²(1) = 12.70, p < .001, Phi = 0.38 (moderate); and for studies that reported the following participant characteristics: language, χ²(1) = 29.58, p < .001, Phi = 0.48 (moderate-to-large); and race/ethnicity + SES + language, χ²(1) = 19.26, p <. 001, Phi = 0.39 (moderate). However, associations were not found between recruitment and retention approaches and whether studies included High SCLD or Low SCLD samples. Further study of NDD researchers’ recruitment and retention approaches that successfully include SCLD families is needed.
... 1st Issue: Inconsistent weights for the scalable number of STE criteria As mentioned previously, the current number of identified STE criteria in BCI applications is 10, and this number could be increased in the future. Although the AHP method has a high success rate when it comes to weighting criteria [26,35], the inconsistency of AHP weighing techniques has not been addressed [36][37][38][39][40][41][42][43], especially when the number of criteria is increased. In AHP, the constructed weights were obtained based on pairwise comparisons. ...

Benchmarking brain–computer interface (BCI) applications, considering all available smart training environment (STE) criteria, is a challenging task due to the following issues: inconsistent weights, static ranks and ranking stability measurements. Therefore, this study aims to develop a dynamic decision-making framework for benchmarking BCI applications based on STE criteria through three integrated phases. In the first phase, the adaptivity of the decision matrix is identified concerning two dimensions: 27 BCI applications as alternatives and 10 STE criteria. In the second phase, the consistency of weights is evaluated and constructed to each STE criterion via the fuzzy-weighted zero-inconsistency (FWZIC) method and the VIekriterijumsko KOmpromisno Rangiranje (VIKOR) method for benchmarking the BCI applications. In the third phase, four sensitive scenarios are developed for measuring the consistency of the STE criteria’s weights and the ranking performance of the BCI applications. The experimental result shows that the ‘ease of use’ STE criterion obtains a high-affected weight with a value of 0.13, while other criteria, augmented reality, hybrid and desktop use (stationary), obtain less weight with a 0.075 value. Additionally, BCI applications A5 and A6 are robust and stable among the others based on the consistency of weights concerning the four scenarios, and they are further candidates to be deployed in real-life applications. The overall ranking results are stable and less affected when applied to the four sensitive scenarios due to the robustness of the integrated FWZIC-VIKOR method of the proposed dynamic framework. The outcome of this framework is objectively validated in terms of five groups, and the ranking results are reliable and the closest to the decision-makers' viewpoints. The proposed framework considers a good solution for choosing a dependable application to support the user and community of BCI systems with a stable STE environment.
... Research has demonstrated that Latinx families with low English proficiency in the United States face increased barriers to accessing autism treatment and report having more unmet therapy needs (Zuckerman et al., 2017). For example, children of non-English-speaking households report receiving fewer hours of individual intervention services than those from English-speaking households (Nguyen et al., 2016). The dearth of Spanishspeaking licensed psychologists in the United States further exacerbates barriers to care as Latinx families report this lack of Spanish-speaking providers as a major reason for their difficulty navigating and accessing services (Angell et al., 2018). ...

Despite consensus on the importance of early detection and intervention for autistic children, health disparities exist, limiting access to timely services. One specific service type in the United States is Individuals with Disabilities Education Act, Part C Early Intervention programs, which are federally funded interventions for children birth-to-three with developmental delays. This study aimed to assess access to Part C, Early Intervention services for children who were evaluated for autism spectrum disorder and to examine factors that predicted parent-reported access to these services. This study extracted sociodemographic and service access data from the medical records of 709 children aged 12–40 months who were evaluated for autism spectrum disorder. Results showed that only 50% of the sample had reportedly accessed Part C, Early Intervention services. Those who identified as Black had decreased odds of having accessed Part C, Early Intervention, relative to those who identified as White, while those with a lower age of first parent concern had increased odds of having accessed Part C, Early Intervention. When inputting the independently significant variables into the model, both variables, identifying as Black and a lower age of first concern, remained significantly associated with accessing Part C, Early Intervention. Future work should investigate how these disparities come to be. Lay abstract Health disparities are defined as preventable differences in the opportunities to achieve optimal health outcomes experienced by marginalized and underrepresented communities. For families with autistic children, health disparities limit accessing early intervention services—which have been found to improve quality of life and other outcomes. One specific early intervention service in the United States is Individuals with Disabilities Education Act, Part C Early Intervention programs, which are federally funded interventions for children birth-to-three with developmental delays. This study adds to this topic by examining which factors impact accessing Part C, Early Intervention services for children who were evaluated for autism. Results showed that only half of the sample received these services despite there being concerns about development for all children. In addition, results showed that those who identified as Black had decreased odds of having accessed Part C, Early Intervention compared to those who identified as White. These results suggest that there are disparities when it comes to accessing important early intervention services that may be negatively impacting the Black autistic community.
... As such, there is an increasing need to identify and provide appropriate intervention services for Hispanic youth with DDs and their caregivers (Note: The term Hispanic is used throughout the remainder of this article, as it is the preferred term of the majority of members of this community; Noe-Bustamante et al., 2020). Unfortunately, research suggests that existing service systems often fail to meet the treatment needs of Hispanics with developmental disabilities (Nguyen et al., 2016). Spanish-speaking families experience additional challenges including fewer intervention hours and more unmet intervention needs, with some studies showing English-language proficiency to be the single most important factor in predicting access to services (Zuckerman et al., 2017). ...

Hispanic/Latinx parents of children with developmental delays/disabilities (DD) face disparities in service access and research participation. In the present study, 60 Spanish-speaking caregivers of young children with DD participated in randomly assigned stress reduction interventions (psychoeducation/support groups or Mindfulness-Based Stress Reduction [MBSR]), followed by behavioral parent training (BPT). Caregiver attendance and satisfaction ratings were measured, and focus groups gathered additional information on caregivers' takeaways from the interventions. Caregivers demonstrated high satisfaction across interventions, with slightly greater preference for psychoeducation/support groups, and qualitative data indicated that the relevance of the information and style of delivery may be responsible. Researchers and clinicians may attain greater engagement with this population by focusing on intervention services that include psychoeducation and peer support elements.
... Evidence from Australia has also indicated that the largest disparity in Medicare spending is more marked during the early years of life (Dalziel et al., 2018(Dalziel et al., , 2020bNguyen et al., 2016). Early childhood is a crucial period for children to utilise health services when needed to achieve optimal health and development (Elgar et al., 2017;Starfield and Simpson, 1993), particularly if a child has special healthcare needs (Dalziel et al., 2018). ...
... Pickard and Ingersoll (2016), for example, found that parents with lower incomes reported less knowledge of autism support services, which in turn was associated with receiving a reduced number of such services. Several studies have found that lower income families access and participate in support services at a reduced rate (Carr et al., 2016;Nguyen et al., 2016;Smith et al., 2020). These data suggest there are likely additional challenges to accessing support services experienced by lower income families. ...

We surveyed New Zealand parents of autistic children to identify their perceived barriers and facilitators to accessing support services, including the influence of a family’s level of financial resourcing. A total of 173 completed surveys were analysed. Service pathway factors were the greatest barrier experienced by participants, whereas facilitators related to providers tended to be most helpful. Lower family income was associated with a higher number of reported barriers. Both lower family income and having a child who identified their gender as non-binary were predictive of rating the extent of barriers higher. Parents of younger or of non-speaking autistic children on average reported a greater number of facilitators. Implications of these results for support service delivery and potential areas for future research are discussed. Lay abstract Parents might have problems in getting support services for their autistic child due to certain barriers. However, there might also be things that can ease or facilitate parents’ access to support services. In this study, New Zealand parents were asked about their experiences in getting support services for their autistic child. We also looked at differences in reported barriers and facilitators based on several demographic factors with a focus on family level of financial resourcing. A total of 173 parents completed a survey. The results suggested that parents experienced several barriers, particularly related to service pathways. Facilitators were also experienced, predominantly related to providers. Financial resourcing predicted the number of parent-reported barriers. Both lower level of family financial resourcing and having a non-binary child predicted parents’ rating of the extent of barriers. Child age and level of speech were predictors for reports of experiencing a higher number of facilitators, with parents of younger children or of non-speaking autistic children reporting a greater number of facilitators. We discuss how these results may be useful to support service delivery and identify areas for future research.
... 11 Yet, autism interventions have historically overrepresented White, middle/high-income participants, 12 despite the racial and socioeconomic disparities in autism service use. 13 Researchers have begun to develop autism interventions specifically tailored for communities of color. 14 However, more work is required to develop approaches that meet the needs of culturally diverse families. ...

Objective: This study examined the short-term impact on child, family, and parent outcomes of a peer-to-peer psychoeducational intervention, Parents Taking Action (PTA) for Black families of children awaiting developmental-behavioral pediatric evaluations. Methods: We targeted parents and other primary caregivers of Black children aged 8 years or younger awaiting a developmental or autism evaluation at an academic tertiary care hospital. Using a single-arm design, we recruited participants directly from the appointment waitlist and used flyers in local pediatric and subspecialty clinics. Eligible participants received a version of PTA adapted for Black children in two 6-week modules delivered synchronously online. In addition to initial baseline demographic data, we collected 4 standardized measures of parent stress and depression, family outcomes (e.g., advocacy), and child behavior at preintervention, midintervention, and postintervention. We calculated effect sizes and used linear mixed models to examine changes over time. Results: Fifteen participants completed PTA, the majority of whom were Black mothers with annual household incomes <$50,000. All children were Black and mostly boys, with an average age of 4.6 years. Parent depression, the family outcome total score, and 3 family outcomes (understanding child's strengths, needs, and abilities; knowing rights and advocating for child; and helping child develop and learn) significantly improved pre-post intervention, with medium to large effect sizes. Furthermore, the family outcome total score and "knowing rights and advocating for child" outcome significantly increased by midintervention (d = 0.62-0.80). Conclusion: Peer-delivered interventions can result in positive outcomes for families awaiting diagnostic evaluations. Further research is needed to confirm findings.
... 19 Large gaps in access to autism services, especially behavioral interventions, have been documented worldwide, including in high-income countries, such as the United States, Canada, and the United Kingdom. [20][21][22][23][24] Studies from other Arab nations similarly point to significant disparities; for example, the mean age at first service access is 3.3 years in Saudi Arabia 25 compared to 2.2 years in the United States. 26 Our data are consistent with the above research and indicate that services are rarely delivered by autism-specialized centers. ...

Objectives: To explore access to intervention services for children with autism spectrum disorder (ASD) in Jordan. Methods: We used prospective cross sectional design and survey methodology to collect information from the parents of a convenient sample of children with ASD aged 2.5-17 years and who attended pediatric neurology clinics in 3 different university affiliated hospitals in 3 geographic areas in Jordan from February to December 2018. Results: We interviewed parents of 274 children with ASD. One hundred ninety-six (71.5%) received rehabilitation services. The average age at first session was 3.9 years. The most common services received were behavioral therapy (182; 66.4%). The average weekly hours were highest for speech and behavioral therapy; 6.25 and 6.64 respectively. Private centers for developmental disabilities were the most commonly used followed by private centers for ASD. The most common barriers were costs (138; 58%) and transportation (88; 37.5%). Most parents (198; 72.3%) prefer to receive rehabilitation in a specialized center for autism, and most did not want to receive training to train their child themselves. Conclusion: Most children with ASD in Jordan have limited access to recommended autism services. The development of future interventions must consider the needs of those living in limited resource regions.

Background: Families whose child has unexplained intellectual or developmental differences often hope that a genetic diagnosis will lower barriers to community-based therapeutic and support services. However, there is little known about efforts to mobilize genetic information outside the clinic or how socioeconomic disadvantage shapes and constrains outcomes. Methods: We conducted an ethnographic study with predominantly socioeconomically disadvantaged families enrolled in a multi-year genomics research study, including clinic observations and in-depth interviews in English and Spanish at multiple time points. Coding and thematic development were used to collaboratively interpret fieldnotes and transcripts. Results: Thirty-two families participated. Themes included familial expectations that a genetic diagnosis could be translated into information, understanding, and assistance to improve the quality of a child's day-to-day life. After sequencing, however, genetic information was not readily converted into improved access to services beyond the clinic, with families often struggling to use a genetic diagnosis to advocate for their child. Conclusion: Families' ability to use a genetic diagnosis as an effective advocacy tool beyond the clinic was limited by the knowledge and resources available to them, and by the eligibility criteria used by therapeutic service providers' - which focused on clinical diagnosis and functional criteria more than etiologic information. All families undertaking genomic testing, particularly those who are disadvantaged, need additional support to understand the limits and potential benefits of genetic information beyond the clinic.

Earlier autism diagnosis, the importance of early intervention, and development of specific interventions for young children have contributed to the emergence of similar, empirically supported, autism interventions that represent the merging of applied behavioral and developmental sciences. "Naturalistic Developmental Behavioral Interventions (NDBI)" are implemented in natural settings, involve shared control between child and therapist, utilize natural contingencies, and use a variety of behavioral strategies to teach developmentally appropriate and prerequisite skills. We describe the development of NDBIs, their theoretical bases, empirical support, requisite characteristics, common features, and suggest future research needs. We wish to bring parsimony to a field that includes interventions with different names but common features thus improving understanding and choice-making among families, service providers and referring agencies.

Presently there is no consensus on the specific behavioral treatment of choice for targeting language in young nonverbal children with autism. This randomized clinical trial compared the effectiveness of a verbally-based intervention, Pivotal Response Training (PRT) to a pictorially-based behavioral intervention, the Picture Exchange Communication System (PECS) on the acquisition of spoken language by young (2-4 years), nonverbal or minimally verbal (≤9 words) children with autism. Thirty-nine children were randomly assigned to either the PRT or PECS condition. Participants received on average 247 h of intervention across 23 weeks. Dependent measures included overall communication, expressive vocabulary, pictorial communication and parent satisfaction. Children in both intervention groups demonstrated increases in spoken language skills, with no significant difference between the two conditions. Seventy-eight percent of all children exited the program with more than 10 functional words. Parents were very satisfied with both programs but indicated PECS was more difficult to implement.

Abstract There is greater identification of children with autism spectrum disorders (ASD) and, as a result, more attention to specialty services to address the challenges children with ASD face. Along with the growth in identification of ASD is a growth in the population of Latino children, yet there is some evidence that disparities exist in diagnosis and services between Latino and non-Latino White children. This study further documents these disparities and investigates the mechanisms that may contribute to them. Diagnosis and specialty services were compared between 48 Latino and 56 non-Latino White children diagnosed with ASD, and factors that contribute to differences are explored. Results show that Latino children were diagnosed almost one year later than White children, received fewer specialty services, and had higher unmet service needs. Factors that accounted for differences in the number of services received were maternal level of education and the number of sources of knowledge about autism. Findings suggest that service providers need to work to provide greater awareness and knowledge about autism, and make services more accessible to Latino families.

This evidence base update examines the level of empirical support for interventions for children with autism spectrum disorder (ASD) younger than 5 years old. It focuses on research published since a previous review in this journal (Rogers & Vismara, 2008119. Rogers, S. J. & Vismara, L. A. (2008). Evidence-based comprehensive treatments for early autism. Journal of Clinical Child & Adolescent Psychology, 37, 8–38. doi:10.1080/15374410701817808[Taylor & Francis Online], [PubMed], [Web of Science ®]View all references). We identified psychological or behavioral interventions that had been manualized and evaluated in either (a) experimental or quasi-experimental group studies or (b) systematic reviews of single-subject studies. We extracted data from all studies that met these criteria and were published after the previous review. Interventions were categorized across two dimensions. First, primary theoretical principles included applied behavior analysis (ABA), developmental social-pragmatic (DSP), or both. Second, practice elements included scope (comprehensive or focused), modality (individual intervention with the child, parent training, or classrooms), and intervention targets (e.g., spoken language or alternative and augmentative communication). We classified two interventions as well-established (individual, comprehensive ABA and teacher-implemented, focused ABA + DSP), 3 as probably efficacious (individual, focused ABA for augmentative and alternative communication; individual, focused ABA + DSP; and focused DSP parent training), and 5 as possibly efficacious (individual, comprehensive ABA + DSP; comprehensive ABA classrooms; focused ABA for spoken communication; focused ABA parent training; and teacher-implemented, focused DSP). The evidence base for ASD interventions has grown substantially since 2008. An increasing number of interventions have some empirical support; others are emerging as potentially efficacious. Priorities for future research include improving outcome measures, developing interventions for understudied ASD symptoms (e.g., repetitive behaviors), pinpointing mechanisms of action in interventions, and adapting interventions for implementation with fidelity by community providers.

We prospectively examined evidence for the sustained effects of early intervention based on a follow-up study of 39 children with ASD who began participation in a randomized clinical trial testing the effectiveness of the Early Start Denver Model (ESDM) at age 18 to 30 months. The intervention, conducted at a high level of intensity in-home for 2 years, showed evidence of efficacy immediately posttreatment. This group of children was assessed at age 6 years, 2 years after the intervention ended, across multiple domains of functioning by clinicians naive to previous intervention group status. The ESDM group, on average, maintained gains made in early intervention during the 2-year follow-up period in overall intellectual ability, adaptive behavior, symptom severity, and challenging behavior. No group differences in core autism symptoms were found immediately posttreatment; however, 2 years later, the ESDM group demonstrated improved core autism symptoms and adaptive behavior as compared with the community-intervention-as-usual (COM) group. The 2 groups were not significantly different in terms of intellectual functioning at age 6 years. Both groups received equivalent intervention hours during the original study, but the ESDM group received fewer hours during the follow-up period. These results provide evidence that gains from early intensive intervention are maintained 2 years later. Notably, core autism symptoms improved in the ESDM group over the follow-up period relative to the COM group. This improvement occurred at the same time that the ESDM group received significantly fewer services. This is the first study to examine the role of early ESDM behavioral intervention initiated at less than 30 months of age in altering the longer-term developmental course of autism.

This study examines joint choices of level of employment and child care arrangement using a sample of mothers of preschool children from the National Survey of Families and Households. Including part-time employment in the choice model is important because nearly 40% of mothers of preschool children combine employment and caregiving by working part-time. Results suggest a unique combination of factors affecting the choice of part-time employment combined with care by a parent or relative. Mothers employed part-time and using nonmarket care are more likely to be white, married, Catholic, and in a service or sales occupation with a variable schedule. Very few African-American mothers are employed part-time. Implications are discussed.

This study examines child and family characteristics thought to affect the dosage and type of common in-school and private services (i.e., speech language therapy (SLT), occupational therapy (OT) and applied behavior analysis (ABA)) received by children with ASD. Participants included 137 families and their preschool-aged children with ASD from four states: Colorado, Florida, Minnesota, and North Carolina. Our results indicated child and family characteristics did impact the type and dosage of services used. In the school setting, Hispanic children received a smaller dose of SLT and OT than White children. Children with greater cognitive impairments received more SLT and those with more severe symptoms of autism received a larger dosage of OT. In the private setting, higher levels of caregiver stress were related to increase usage of OT. Caregivers with a higher socioeconomic status were more likely to enroll their children in OT and ABA. Implications for practice and policy are discussed, including the need to better understand and remediate differences in service provision across socioeconomic and minority status.

This study reports on predictors of outcome in 332 children, aged 2–7 years, enrolled in the community-based Intensive Behavioral Intervention (IBI) program in Ontario, Canada. Data documenting children's progress were reported in an earlier publication (Perry et al., 2008). The present paper explores the degree to which four predictors (measured at intake to IBI) are related to children's outcomes: age at entry, IQ, adaptive scores, and autism severity. Outcome variables examined include: post-treatment scores for: autism severity, adaptive behavior, cognitive level, rate of development in IBI, and categorical progress/outcomes (seven subgroups). All four types of predictors were related to children's outcomes, although initial cognitive level was the strongest predictor. In addition, two subgroups of the sample are examined further. Children who were most successful in the program and achieved average functioning had higher developmental levels at intake, were considerably younger than the rest of the children, and were in treatment longer than children in other outcome categories. Children who were least successful in the program and made essentially no progress did not differ appreciably from the remainder of the group. Implications of these results for decision-making are discussed.
