This study examined the group and individual part score profiles of individuals with mild intellectual disability (ID) who participated in a clinical validity study supporting the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) and a comparison group without ID derived from the WISC-V norming sample. Descriptive analyses revealed…

This report provides updated prevalence estimates for diagnosed autism spectrum disorder, intellectual disability, and other developmental delay among children 3-17 years from the 2019-2021 National Health Interview Survey, with differences in prevalence examined between years and by sex, age group, and race and Hispanic origin. Estimates are also…

Genetic tests, such as Fragile X and Chromosomal Microarray, are recommended as a standard of care during the evaluation of autism spectrum disorder (ASD) and other neurodevelopmental disorders. However, previous research demonstrates low rates of genetic testing. This study aimed to identify the rates of genetic testing and patient demographic…

Adults with Intellectual and Developmental Disabilities (IDD) are aging with chronic health issues. However, little is known about the racial disparities in chronic health conditions among adults with IDD. Do racial and ethnic minority adults with IDD experience elevated risk of chronic health conditions like in the general population? How do…

Transition outcomes for Black youth with intellectual and developmental disabilities are especially dire, lagging even further behind already poor outcomes among their White peers. Self-determination is a key factor in predicting better outcomes, but it is unclear how self-determination is fostered or hindered within the transition process for…

Barriers to health care access can greatly affect one's health status. Research shows that U.S. adults with intellectual and developmental disabilities (IDD) have poor health and face barriers such as long waits for appointments. However, whether barriers differ by race and ethnicity has not been examined. We conducted a secondary data analysis…

This 10-year study followed 134 caregivers of young adults with autism and intellectual disability, examining the effects of caregivers' coping strategies, sociodemographic features, and young adult symptomatology on caregiver well-being and depression. Lower caregiver education and higher young adult externalizing behaviors predicted lower…

Background: We examined differences in food selectivity by gender and parent race/ethnicity in children with intellectual disabilities. Method: A convenience sample of 56 children with intellectual disabilities was analysed. A modified Youth/Adolescent Food Frequency Questionnaire and a 3-day food record were used to measure child food refusal…

Postsecondary education opportunities for students with intellectual disability (ID) steadily increased between 2015 and 2020, in part due to a federal model demonstration program called the Transition and Postsecondary Program for Students with Intellectual Disability (TPSID). This program, implemented by the Office of Postsecondary Education,…

Special education provides an accessible route for children with intellectual disabilities (ID) to be evaluated and to access services. Understanding the factors that influence special education eligibility can provide valuable insight into the school evaluation and eligibility process. This study used structural equation modeling to examine the…

Objective: Transition from school to early adulthood incurs many changes and may be associated with deterioration in general health in youth with autism. We aimed to investigate this. Method: The National Longitudinal Transitions Study-2 is a USA nationally representative sample of youth receiving special education services, aged 13-17 at wave 1,…

Opportunities and experiences for all students, including students with intellectual and developmental disabilities, to build self-determination abilities and skills is critical to enable positive postsecondary outcomes (e.g., competitive and integrated employment, community access participation). However, racially and ethnically marginalized…

Background: Oppositional Defiant Disorder (ODD) appears more prevalent among children with intellectual disabilities (ID) as compared to children with typical development. However, it remains unclear what drives this difference. Methods: Data from 70 youth with typical development (TD) and 20 youth with ID were drawn from (The Collaborative Family…

In this paper I study the impact of court-mandated school desegregation by race on student suspensions and special education classification. Simple descriptive statistics using student enrollment and outcome data collected from the largest school districts across the country in the 1970s and 1980s show that Black-White school integration was…

Children with autism spectrum disorder have a high risk of vision problems yet little is known about their vision care. This cross-sectional survey study, therefore, examined vision care among 351 children with autism spectrum disorder ages 6-17 years in the United States or Canada who were enrolled in the Autism Treatment Network Registry. Vision…
