Still Left Behind: Fewer Black School-Aged Youth Receive ASD Diagnoses Compared to White Youth

Resilience and strengths in the Black autism community in the United States: A scoping review

Gaps in research knowledge pertaining to resiliency factors and strengths among the Black autism community, inclusive of autistic persons and their support system exist. A scoping review was conducted to further explore quantitative, qualitative, and mixed methods studies that investigate resiliency factors and related strengths in the Black autism community in the United States. A total of 436 articles were identified, with 28 studies included in the final review. Results demonstrated that (1) strengths of Black autistic persons across the life course have been disregarded in research; (2) Black caregiver advocacy, while common, is also a developmental process that can be supported by community-based interventions; (3) informal supports including family and friends play an instrumental role in supporting the well-under investigated being of Black parents of autistic children; and (4) spirituality is often endorsed by Black caregivers of autistic children, such as playing a role in acceptance of the autism diagnosis and with coping with difficult life situations. Research and practice implications are discussed.

Survey of the Landscape of Society Practice Guidelines for Genetic Testing of Neurodevelopmental Disorders

Genetic testing of patients with neurodevelopmental disabilities (NDDs) is critical for diagnosis, medical management, and access to precision therapies. Because genetic testing approaches evolve rapidly, professional society practice guidelines serve an essential role in guiding clinical care; however, several challenges exist regarding the creation and equitable implementation of these guidelines. In this scoping review, we assessed the current state of United States professional societies' guidelines pertaining to genetic testing for unexplained global developmental delay, intellectual disability, autism spectrum disorder, and cerebral palsy. We describe several identified shortcomings and argue the need for a unified, frequently updated, and easily-accessible cross-specialty society guideline. ANN NEUROL 2024.

Gender, assigned sex at birth, and gender diversity: Windows into diagnostic timing disparities in autism

LAY ABSTRACT

Later autism diagnosis is associated with risk for mental health problems. Understanding factors related to later autism diagnosis may help reduce mental health risks for autistic people. One characteristic associated with later autism diagnosis is female sex. However, studies often do not distinguish sex assigned at birth and gender identity. Gender diversity may be more common in autistic relative to neurotypical people, and autism is more common in gender-diverse populations. We studied age at autism diagnosis by sex assigned at birth, gender identity, and gender diversity (gender-diverse vs cisgender) status, separately. We studied three separate autistic samples, each of which differed in how they were diagnosed and how they were recruited. The samples included 193 persons (8.0-18.0 years) from a research-recruited academic medical center sample; 1,550 people (1.3-25.4 years) from a clinic-based sample; and 244 people (18.2-30.0 years) from a community-enriched sample. We found significant differences in the clinic-based and community-enriched samples. People assigned female sex at birth were diagnosed with autism significantly later than people assigned male at birth. People of female gender were diagnosed significantly later than people of male gender. Gender-diverse people were diagnosed significantly later than cisgender people. Sex assigned at birth, gender identity, and gender diversity may each show unique relationships with age of autism diagnosis. Differences in how autistic people are diagnosed and recruited are important to consider in studies that examine sex assigned at birth or gender identity. More research into autism diagnosis in adulthood is needed.

Toward Equity in Research on Intellectual and Developmental Disabilities

Lack of diversity in IDD research is typically conceptualized only in terms of (1) recruitment of samples that do not appropriately represent the sociodemographics of the population, or (2) the limited number of researchers from historically marginalized backgrounds. Critically, the field also suffers from over-reliance on perspectives and social systems of dominant culture-both in how disability is regarded and in relation to other dimensions of identity and culture. These lenses lead to research findings that reinforce, rather than reduce, social inequities. We propose a framework that minimizes reliance on diagnostic categories, shifts from deficit- to person-centered models, acknowledges people's multiple identities, and includes self-advocates and diverse communities as partners in the research enterprise. The systems change necessary to support this framework is described.

ECHO (Extension for Community Healthcare Outcomes) Autism STAT: A Diagnostic Accuracy Study of Community-Based Primary Care Diagnosis of Autism Spectrum Disorder

OBJECTIVE

Children can be reliably diagnosed with autism spectrum disorder (ASD) by a highly trained clinician as early as 12 to 24 months of age, but recent estimates indicate that the average age of diagnosis is 4.4 years. We hypothesized that trained primary care physicians and practitioners can reliably and accurately diagnose children 14 to 48 months with unambiguous symptoms of ASD.

METHODS

Through this diagnostic accuracy study, 20 patients diagnosed with ASD by clinicians trained through the ECHO (Extension for Community Healthcare Outcomes) Autism STAT program participated in an independent gold-standard evaluation at a regional autism center. Caregiver perceptions of the diagnostic process were also assessed.

RESULTS

Of the 20 patients who received a diagnosis of ASD by a trained clinician and completed the study, 19 diagnoses were confirmed by a gold-standard evaluation. Caregivers indicated that undergoing diagnosis in their local community rather than an autism specialty center was helpful (4.8/5 on a 5-point Likert scale, n = 19). Results of this study demonstrate that primary care clinicians can be trained to reliably diagnose ASD in children 14 to 48 months with unambiguous symptoms.

CONCLUSION

Diagnosis in the primary care setting may lead to earlier diagnosis and quicker connection to evidence-based therapies and interventions. Given the potential impact of increasing access to high-quality diagnostic services, the role of primary care clinicians in the diagnosis of ASD should be further evaluated.

Examination of Race and Autism Intersectionality Among African American/Black Young Adults

Background

African American/Black (AA/B) young adults with diagnoses of autism spectrum disorders rarely are studied in a way that acknowledges both their racial identity and their autism diagnosis. Little is known about intersectional oppression in the lives of these young adults. Early adulthood is a time when a young people of color may come to terms with a society that may not treat them fairly and equally due to their race. Autistic AA/B young adults may be even more vulnerable to stress and psychological disempowerment due to the added impact of negative experiences of being Black and having an autism diagnosis.

Methods

Thirty-two autistic and 30 non-autistic AA/B young adults took part in an online survey examining risk factors of everyday discrimination, perceived stress and potential protective factors of psychological empowerment, and Black identity. Differences in score measures for the autistic and non-autistic samples were examined along with the predictors of perceived stress assessed. Frequencies of intersectional discrimination experiences were also examined.

Results

Autistic AA/B participants reported significantly less everyday discriminatory experiences than non-autistic AA/B participants, whereas perceived stress was not significantly different between the two groups. The majority of non-autistic AA/B participants endorsed race as their prime source of experiences of discrimination, whereas autistic AA/B participants also cited being autistic as a major contributor to reports of discrimination. Although the autistic group had significantly lower reports of self-determination, they reported higher on the Black identity, private regard scale, pertaining to feelings about group membership, which can be considered a protective factor. There is heterogeneity in reasons for discriminatory experiences for autistic AA/B young adults whereby some of the participants (12%-30%) endorsed race + disability as dual reasons for experiencing regular discrimination.

Conclusions

Mental health clinicians and other direct service providers working with autistic AA/B young adults should understand that intersecting identities of race and disability may be at play when they are working with these individuals, and that treatment should consider these factors.
