Age of diagnosis among Medicaid-enrolled children with autism, 2001-2004

Outreach and Engagement Efforts in Research on Down Syndrome: An NIH INCLUDE Working Group Consensus Statement

The National Institutes of Health formulated the Outreach and Engagement Working Group in Fall of 2019 to support the objectives of the INCLUDE Project (INvestigation of Co-occurring conditions across the Lifespan to Understand Down syndromE). This Working Group consisted of a multi-disciplinary team of stakeholders in research on Down syndrome that met to discuss best practices for outreach and engagement to Down syndrome communities, with an emphasis on representation and diversity. This review and consensus paper describes the importance of increasing representation in DS research for future cohort building and summarizes the priority issues identified by the Working Group members. An overview of Working Group activities is then presented, followed by consensus recommendations and a discussion of future opportunities and challenges.

"On-Time Autism Intervention": A Diagnostic Practice Framework to Accelerate Access

It is well-documented that autism can be reliably diagnosed by age two and that early signs emerge most often between 18 and 24 months. However, despite the increased awareness and focus on early diagnosis, the average age of diagnosis is over 4 years old; even later for Black children and those who are Medicaid-eligible. In this paper, we will propose a framework for accurate and accelerated autism diagnosis for children before age three. The proposed framework emphasizes a collaborative diagnostic process, which relies heavily on Birth to Three provider knowledge and expertise. Considerations for next steps are presented. This approach could increase access to diagnosis of young children soon after first signs of autism emerge.

A space-time analysis of disparities in age at diagnosis of autism spectrum disorder: environmental and socioeconomic risk factors

INTRODUCTION

Early diagnosis of autism is a critical step for gaining early intervention. The earlier interventions begin, the greater chance to reduce symptoms of autism over the lifespan. Despite the improvement in early diagnosis, age at diagnosis varies by residential locations. In order to improve early screening services, this study aims to identify geographic clusters of early and late diagnosis of autism, in addition, it is aimed to compare cases inside the clusters with the rest of the province on characteristics and socioeconomic factors.

MATERIALS AND METHODS

Survey data were collected from 163 autistics born from 1996 to 2011 in Isfahan Province, Iran. As this study found diagnosis of autism occur at an earlier age among children, who on average every 2.5 months increased for each year of age, distance from regression line has been used to determine how early a case was diagnosed compared to other identified cases. After dividing cases into 5 classes based on their distances from the regression line, the ordinal based space-time scan statistic in SaTScan was used to identify geographic areas within specific time periods that have significantly elevated proportions of autistic children who received diagnosis at the earlier or later stages.

RESULTS

The space-time analysis identified two geographic areas that age of diagnosis was inconsistent with the overall study area, the first area has an early diagnosis in central part of Isfahan megacity between 1998 and 2006 (P = .001), the second area shows to have a late diagnosis centered by Najafabad from 2010 through 2015 (P = .007).

CONCLUSIONS

The result of our spatial analysis can be used to evaluate the performance of diagnosis services and additionally provide information to target specific at-risk population for further interventions.

First Alarm and Time of Diagnosis in Autism Spectrum Disorders

Early diagnosis of autism spectrum disorder (ASD) is of paramount importance as it opens the road to early intervention, which is associated with better prognosis. However, early diagnosis is often delayed until preschool or school age. The purpose of the current retrospective study was to explore the age of recognition of first alarming symptoms in boys and girls as well as the age at diagnosis of different subtypes of ASD in a small sample. A total of 128 parents' of children with ASDs were participated in the survey by completing a self-report questionnaire about early signs and symptoms that raised their concern. Parents of children with autism voiced concerns earlier and obtained diagnosis significantly earlier compared to parents of children with Asperger syndrome (p value <0.000). No significant difference (p value<0.05) has been detected between males and females in early manifestation of first signs and symptoms of ASD. The mean age at diagnosis was 3.8 years for autistic disorder, 6.2 years for children with Asperger syndrome and 6.4 years for other, e.g., PDD-NOS. The most commonly reported symptoms were speech and language problems (p value = 0.001) for children who were later diagnosed with autism, while behavior problems (p value = 0.046) as well as difficulties in education at school (p value = 0.013) for children with Asperger syndrome. The gap between early identification and diagnosis pinpoints the urgent need for national systematic early screening, the development of reliable and sensitive diagnostic instruments for infants and toddlers and heightened awareness of early signs of ASD among parents, teachers, and healthcare professionals and providers as well.

Using stakeholder perspectives to guide systematic adaptation of an autism mental health intervention for Latinx families: A qualitative study

Embedded within a Hybrid Type 1 randomized effectiveness-implementation trial in publicly funded mental health services, the current study identified stakeholder recommendations to inform cultural adaptations to An Individualized Mental Health Intervention for Autism Spectrum Disorder (AIM HI) for Latinx and Spanish-speaking families. Recommendations were collected through focus groups with therapists (n = 17) and semi-structured interviews with Latinx parents (n = 29). Relevant themes were identified through a rapid assessment analysis process and thematic coding of interviews. Adaptations were classified according to the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME) to facilitate fit, acceptability, and sustained implementation of AIM HI and classify the content, nature, and goals of the adaptations. Recommended adaptations were classified through FRAME as tailoring training and intervention materials, changing packaging or materials, extending intervention pacing, and integrating supplemental training strategies. Goals for adaptations included improving fit for stakeholders, increasing parent engagement, and enhancing intervention effectiveness. The current study illustrates the process of embedding an iterative process of intervention adaptation within a hybrid effectiveness-implementation trial. The next steps in this study are to integrate findings with implementation process data from the parent trial to develop a cultural enhancement to AIM HI and test the enhancement in a Hybrid Type 3 implementation-effectiveness trial.

Autism Heterogeneity in a Densely Sampled U.S. Population: Results From the First 1,000 Participants in the RI-CART Study

The objective of this study was to establish a large, densely sampled, U.S. population-based cohort of people with autism spectrum disorder (ASD). The Rhode Island Consortium for Autism Research and Treatment (RI-CART) represents a unique public-private-academic collaboration involving all major points of service for families in Rhode Island affected by ASD. Diagnosis was based on direct behavioral observation via the Autism Diagnostic Observation Schedule, Second Edition. For the first 1,000 participants, ages ranged from 21 months to 64 years. Using Geographic Information System and published prevalence rates, the overall cohort is estimated to represent between 20% and 49% of pediatric age persons in Rhode Island with ASD, with demographics representative of U.S. Census. We observed a high rate of co-occurring medical and psychiatric conditions in affected individuals. Among the most prominent findings of immediate clinical importance, we found that females received a first diagnosis of ASD at a later age than males, potentially due to more advanced language abilities in females with ASD. In summary, this is the first analysis of a large, population-based U.S. cohort with ASD. Given the depth of sampling, the RI-CART study reflects an important new resource for studying ASD in a representative U.S. population. Psychiatric and medical comorbidities in ASD constitute a substantial burden and warrant adequate attention as part of overall treatment. Our study also suggests that new strategies for earlier diagnosis of ASD in females may be warranted. Autism Res 2020, 13: 474-488. © 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The Rhode Island Consortium for Autism Research and Treatment (RI-CART) represents a unique public-private-academic collaboration involving all major points of service for families in Rhode Island affected by autism spectrum disorder (ASD). In this article, we provide results from the first 1,000 participants, estimated to represent >20% of affected families in the state. Importantly, we find a later age at first diagnosis of ASD in females, which potentially calls attention to the need for improved early diagnosis in girls. Also, we report a high rate of co-occurring medical and psychiatric conditions in affected individuals.

Implementing an intervention to address challenging behaviors for autism spectrum disorder in publicly-funded mental health services: Therapist and parent perceptions of delivery with Latinx families

OBJECTIVES

As implementation of evidence-based practices (EBPs) in publicly funded children's mental health services has become increasingly common, concerns have been raised about the appropriateness of specific EBPs to the diverse client populations served in these settings. Exploring stakeholder perspectives can provide direction for refinements of EBPs when delivered with Latinx families. The current study used qualitative methods to examine therapist and Latinx parent perceptions of therapist-parent interactions and the intervention process when therapists are trained to deliver AIM HI (An Individualized Mental Health Intervention for ASD), a structured, parent-mediated intervention for autism spectrum disorder (ASD).

METHOD

Therapist and parent participants were a subset of participants from a large-scale community effectiveness trial. Perceptions were gathered through focus groups with therapists (n = 17) and semistructured interviews with Latinx parents (n = 29). Therapists were 94% female, 35% Latinx, and 47% were fluent in Spanish. Parents were 93% female, 100% Latinx, and 66% preferred Spanish. A coding, consensus, co-occurrence and comparison approach was used to analyze data.

RESULTS

Three primary themes emerged: (a) limited parental knowledge about ASD and the need to address knowledge gaps; (b) differing perceptions regarding parental participation in treatment; and (c) identification of influences on parent-therapist interaction, including the cultural value of respeto/deference (emphasized by therapists), and importance of personalismo/personal connection (emphasized by parents).

CONCLUSIONS

The themes provide specific direction for enhancements to AIM HI to maximize engagement of Latinx families. The themes also have broader implications for intervention development and community implementation including refinement of EBPs to facilitate fit and sustained implementation.

Stress and Parents of Children with Autism: A Review of Literature

The purpose of this review is twofold. The first is to synthesize factors that impact parents' experiences of caring for a child with autism spectrum disorder (ASD); the second is to identify factors that impact parental stress and parental decision-making to use autism services or not. Parents of children with ASD score higher on levels of stress than other groups of parents. The daily challenges of caring for the child are endless and effect all aspects of the child's care as well as the parent's mental health and ability to manage the needs of the child and family. Understanding more about the challenges parents face will provide direction for research, intervention development, and practice. Accordingly, a search was conducted using CINAHL and Medline. Inclusion criteria included articles available in full text, published in English, and focused on children with ASD distinct from other diagnoses, as well as parental experiences of caring for a child with ASD. Articles (N = 132) that met the inclusion criteria were summarized. Challenging aspects of the child's diagnosis and care are discussed, as well as the factors that impact parental stress and decision-making to use autism services. Recommendations for research and practice include interventional development related to early diagnosis, disparity, access to care, parental decision-making to use autism services, and parental stress management.

Limited fine motor and grasping skills in 6-month-old infants at high risk for autism

Atypical motor behaviors are common among children with autism spectrum disorders (ASD). However, little is known about onset and functional implications of differences in early motor development among infants later diagnosed with ASD. Two prospective experiments were conducted to investigate motor skills among 6-month-olds at increased risk (high risk) for ASD (N1  = 129; N2  = 46). Infants were assessed using the Mullen Scales of Early Learning (MSEL) and during toy play. Across both experiments, high-risk infants exhibited less mature object manipulation in a highly structured (MSEL) context and reduced grasping activity in an unstructured (free-play) context than infants with no family history of ASD. Longitudinal assessments suggest that between 6 and 10 months, grasping activity increases in high-risk infants.

Children's compliance with American Academy of Pediatrics' well-child care visit guidelines and the early detection of autism

This study estimated compliance with American Academy of Pediatrics (AAP) guidelines for well-child care and the association between compliance and age at diagnosis in a national sample of Medicaid-enrolled children with autism (N = 1,475). Mixed effects linear regression was used to assess the relationship between compliance and age at diagnosis. Mean age at diagnosis was 37.4 (SD 8.4) months, and mean compliance was 55 % (SD 33 %). Children whose care was compliant with AAP guidelines were diagnosed 1.6 months earlier than children who received no well-child care. Findings support that the timely receipt of well-child care may contribute to earlier detection. Additional research on the contribution of compliance, well-child visit components and provider characteristics on the timely diagnosis of autism is needed.

Genetic testing and genetic counseling among Medicaid-enrolled children with autism spectrum disorder in 2001 and 2007

The rise in the prevalence of autism spectrum disorder (ASD) has resulted in increased efforts to understand the causes of this complex set of disorders that emerge early in childhood. Although research in this area is underway and yielding useful, but complex information about ASD, guidelines for the use of genetic testing and counseling among children with ASD conflict. The purpose of this study was to determine the frequency of use of genetic testing and counseling before the widespread implementation of clinical chromosomal microarray (CMA) to establish a baseline for the use of both services and to investigate potential disparities in the use of both services among children with ASD. We found that about two-thirds of children with ASD received genetic testing or counseling and the use of both services is increasing with time, even in the pre-CMA era. Being female and having a comorbid intellectual disability diagnosis both increased the likelihood of receiving genetic testing and genetic counseling. Initial discrepancies in the use of both services based on race/ethnicity suggest that troubling disparities observed in other services delivered to children with ASD and other mental health disorders persist in genetic testing and counseling as well. These results should incentivize further investigation of the impact of genetic testing and counseling on children with ASD and their families, and should drive efforts to explore and confront disparities in the delivery of these services, particularly with the advancing scientific research on this topic.

Disparity of care for children with parent-reported autism spectrum disorders

OBJECTIVE

Although children with autism spectrum disorders (ASDs) are eligible to receive special education services via an individualized education program (IEP), approximately 12% to 20% do not. Our objective was to determine which clinical and demographic characteristics are associated with IEP receipt among a nationally representative sample of children with ASD.

METHODS

Using data from the 2007 National Survey of Children's Health, we determined which clinical and demographic covariates are associated with IEP receipt for children ages 6 to 17 years with a current, parent-reported ASD diagnosis (n = 759). Logistic regression models were used to assess the association of covariates with IEP receipt. Application of weighting techniques made the findings representative of the noninstitutionalized population of US children 6 to 17 years old.

RESULTS

In the weighted model, 90% of children with ASD receive an IEP. Maternal education level above high school (adjusted odds ratio [aOR] 4.08, P = .01) and presence of perceived need for coordination of care (aOR 3.62, P = .02) were associated with IEP receipt, while Hispanic children were less likely to receive an IEP compared with white children (aOR 0.12, P = .001). The following factors were not associated with IEP receipt: severity of ASD, speech, and behavior problems.

CONCLUSIONS

For children with ASD in the United States, socioeconomic factors, not disability severity, are associated with IEP receipt. Future research should address methods to overcome this disparity in care. Health care providers may help to advocate for appropriate educational services for patients with ASD.

Access to care for children with autism in the context of state Medicaid reimbursement

This paper examines the role of state residence and Medicaid reimbursement rates in explaining the relationship between having autism and access to care for children. Three questions are addressed: (1) Is there variation across states in the relationship between having autism and access to care? (2) Does taking account of state residence explain a significant amount of the variation in this relationship? (3) Does accounting for Medicaid reimbursement rates enhance our understanding of this relationship? Data from the 2005 National Survey of Children with Special Health Care Needs were combined with state characteristics to estimate a hierarchical generalized linear model of the association between state residence, Medicaid reimbursement rate and problems accessing care for children with special health care needs with and without autism. Findings indicate there is significant variation between states in the relationship between having autism and problems accessing care, and accounting for state residence explains a significant amount of variation in the model. Medicaid reimbursement rates have an independent effect on access to care for children with autism: when families raising children with autism live in states with higher reimbursement rates, they have lower odds of experiencing problems accessing care. The state context in which families live impacts access to care for children with autism. Moreover, when families live in states with higher Medicaid reimbursement rates, they are less likely to experience problems getting care. The value of this analysis is that it helps identify where to look for strategies to improve access.

Parenting-related stress and psychological distress in mothers of toddlers with autism spectrum disorders

BACKGROUND

Parents of children with autism spectrum disorders (ASDs) are at risk for higher stress levels than parents of children with other developmental disabilities and typical development. Recent advances in early diagnosis have resulted in younger children being diagnosed with ASDs but factors associated with parent stress in this age group are not well understood.

AIMS

The present study examined parenting-related stress and psychological distress in mothers of toddlers with ASD, developmental delay without ASD (DD), and typical development. The impact of child problem behavior and daily living skills on parenting-stress and psychological distress were further investigated.

METHODS

Participants were part of a larger research study on early ASD intervention.

RESULTS

Parent self-report of parenting-related stress and psychological distress was utilized. Parents of toddlers with ASD demonstrated increased parenting-related stress compared with parents of toddlers with DD and typical development. However, psychological distress did not differ significantly between the groups. Child behavior problems, but not daily living skills emerged as a significant predictor of parenting-related stress and psychological distress. This was true for both mothers of children with ASD and DD.

CONCLUSIONS

These finding suggest that parents' abilities to manage and reduce behavior problems is a critical target for interventions for young children with ASD and DD in order to improve child functioning and decrease parenting-related stress.

Utility of the social communication questionnaire-current and social responsiveness scale as teacher-report screening tools for autism spectrum disorders

Limited research exists regarding the role of teachers in screening for Autism Spectrum Disorders (ASD). The current study examined the use of the Social Communication Questionnaire (SCQ) and Social Responsiveness Scale (SRS) as completed by parents and teachers about school-age children from the Simons Simplex Collection. Using the recommended cutoff scores in the manuals and extant literature, the teacher-completed SCQ and SRS yielded lower sensitivity and specificity values than would be desirable; however, lowering the cutoff scores on both instruments improved sensitivity and specificity to more adequate levels for screening purposes. Using the adjusted cutoff scores, the SRS teacher form appears to be a slightly better screener than the SCQ. Implications and limitations are discussed, as well as areas for future research.

Parent report of community psychiatric comorbid diagnoses in autism spectrum disorders

We used a national online registry to examine variation in cumulative prevalence of community diagnosis of psychiatric comorbidity in 4343 children with autism spectrum disorders (ASD). Adjusted multivariate logistic regression models compared influence of individual, family, and geographic factors on cumulative prevalence of parent-reported anxiety disorder, depression, bipolar disorder, and attention deficit/hyperactivity disorder or attention deficit disorder. Adjusted odds of community-assigned lifetime psychiatric comorbidity were significantly higher with each additional year of life, with increasing autism severity, and with Asperger syndrome and pervasive developmental disorder-not otherwise specified compared with autistic disorder. Overall, in this largest study of parent-reported community diagnoses of psychiatric comorbidity, gender, autistic regression, autism severity, and type of ASD all emerged as significant factors correlating with cumulative prevalence. These findings could suggest both underlying trends in actual comorbidity as well as variation in community interpretation and application of comorbid diagnoses in ASD.

Factors affecting age at initial autism spectrum disorder diagnosis in a national survey

Entry into early intervention depends on both age of first parent concern (AOC) and age at initial autism spectrum disorder (ASD) diagnosis (AOD). Using data collected from a national online registry from 6214 children diagnosed with an ASD between 1994 and 2010 in the US, we analyzed the effect of individual, family, and geographic covariates on AOC and AOD in a multivariate linear regression model with random effects. Overall, no single modifiable factor associated with AOC or AOD emerged but cumulative variation in certain individual- and family-based features, as well as some geographic factors, all contribute to AOC and AOD variation. A multipronged strategy is needed for targeted education and awareness campaigns to maximize outcomes and decrease disparities in ASD care.

Marital Quality and Families of Children with Developmental Disabilities

In the current review, we highlight recent research on marital quality in parents of children with developmental disabilities (DD) and discuss the child and family factors that account for why some marriages fare better than others. We will also discuss the need for the field of DD to broaden its perspective on marital quality and to examine the impact of marriages on child well-being and the well-being of parents. The clinical implications of recent research findings on marital quality for improving supports and interventions for families of children with DD are discussed. A theoretical framework and model of marriage and parent and child psychosocial well-being in the context of child disability is proposed and a roadmap for future research is provided.
