Black Families' Experiences of Developmental Screening: Review of Well-Child Visits to Inform Enhanced Autism Spectrum Disorder Risk Assessment

Screening Options in Autism Telediagnosis: Examination of TAP, M-CHAT-R, and DCI Concordance and Predictive Value in a Telediagnostic Model

Tele-assessment of autism in early childhood has increased. However, it is unclear how autism screening tools (M-CHAT-R, DCI) function as part of tele-assessment and relate to a commonly used tele-assessment instrument, the TAP. 361 families from a clinically referred sample of children (mean age: 27.63 months, sd = 4.86 months) completed the M-CHAT-R and DCI prior to a tele-assessment visit utilizing the TAP. Data was collected on demographic background, measure scores, and diagnostic outcome. No significant differences in measure scores or diagnostic findings emerged in age at referral, age group, age at diagnosis, or child sex, ethnicity, or racial background. The M-CHAT-R and DCI correlated strongly and positively. Older age was associated with lower risk scores on screening instruments. Children with autism had significantly higher scores on all screener and subdomain scores, with the exception of DCI Behavior. Subdomains of the DCI emerged as the strongest predictor of diagnostic outcome. Both the DCI total score and the M-CHAT-R significantly related to diagnostic outcome and TAP score in this tele-assessment model, regardless of child age or sex. Findings also support use of the DCI for children under 24 months of age.

Implementation of the Infant-Toddler Checklist in Swedish child health services at 18 months: an observational study

BACKGROUND

Communication and language disorders are common conditions that emerge early and negatively impact quality of life across the life course. Early identification may be facilitated using a validated screening tool such as the Infant-Toddler Checklist (ITC). We introduced the ITC at the 18-month visit to child health services (CHS) in a Swedish county. Using the RE-AIM implementation framework, this study assessed the implementation of the ITC according to five key dimensions: reach, effectiveness, adoption, implementation and maintenance.

METHODS

This observational study used medical records at CHS as data source. Data were collected from children who visited a child health nurse at 17-22 months. The sample included 2633 children with a mean age of 17.8 months, 1717 in the pre-implementation group and 916 in the post implementation group. We calculated the ITC completion rate (reach) and use at each site (adoption). We compared rates of referral to speech and language therapy (effectiveness) before and after implementation of the ITC using OR and 95% CIs. We described actions to facilitate implementation and maintenance of ITC screening over time.

RESULTS

The overall screening rate was 93% (reach) which increased from 80% initially to 94% at the end of the 2-year period (maintenance). All centres used the ITC (adoption). The ITC screen positive rate was 14%. Of children who had reached at least 24 months (n=2367), referral rate was 0.4% pre-implementation versus 6.9% post implementation (OR=18.17, 95% CI 8.15, 40.51, p<0.001) (effectiveness). Implementation strategies included training sessions, collaboration, written and automatic procedures and modifications to the medical records system.

CONCLUSION

The implementation of the ITC was associated with high reach, higher referral rate, complete adoption, and sustained maintenance over time.

Exploring Factors of Diagnostic Timing Among Black Autistic Youth

The goal of the present study was to compare profiles among Black families of autistic youth who were identified Early (≤ 2 years of age), Mid (age 3 or 4), and Delayed (≥ 5 years of age) to better identify the characteristics that contribute to early ASD identification and delayed ASD identification. Black caregivers with autistic youth (N = 101) were divided into Early (N = 34), Mid (N = 39), and Delayed (N = 28) groups and compared on (a) the age at which signs of autism signs were first noticed, (b) wait times, (c) previous misdiagnoses rates, and (d) racial barriers experienced during the diagnostic process. The results revealed differences between the diagnostic profiles. Specifically, (a) Delayed families noticed the first signs of autism significantly later, (b) Early families had significantly smaller wait times between age of noticing signs of autism and age of receiving the diagnosis, (c) the odds of receiving a later or delayed autism diagnosis was nearly three times higher for caregivers who reported receiving a misdiagnosis, and (d) there were no significant differences in racial barriers experienced between Early, Mid, and Delayed families. Challenges in receiving a timely diagnosis remain for some Black autistic youth. To improve early identification for Black autistic youth who are at risk for receiving delayed diagnostic care, further research should examine factors and practices that improve autism knowledge among professionals and caregivers, enhance assessment practices, and integrate culturally responsive practices into assessment and screening procedures.

Screening, Diagnosis, and Intervention for Autism: Experiences of Black and Multiracial Families Seeking Care

PURPOSE

Despite advances in screening and awareness, Black and multiracial families continue to experience challenges when seeking an autism diagnosis for their children.

METHODS

We surveyed 400 Black and multiracial families of young children with autism from an existing research database in the United States about their retrospective diagnostic experiences. We gathered quantitative and qualitative data and engaged in iterative coding to understand timing and content of first concerns, families' experiences of care providers and systems, and the impact of race and culture on accessing care.

RESULTS

Families provided examples of early developmental concern and described provider, systemic, and cultural barriers and facilitators to care. Families also provided insight into the influence of culture and made recommendations on how the medical system could better care for Black and multiracial families of children with autism.

CONCLUSIONS

Results add to a growing body of literature supporting the need for culturally sensitive and accessible care related to developmental monitoring, diagnosis, and follow-up care for Black and multiracial children.

Diagnostic Evaluation of Autism Spectrum Disorder in Pediatric Primary Care

BACKGROUND AND OBJECTIVES

Children with autism spectrum disorder (ASD) continue to experience significant delays in diagnosis and interventions. One of the main factors contributing to this delay is a shortage of developmental-behavioral specialists. Diagnostic evaluation of ASD by primary care pediatricians (PCPs) has been shown to be reliable and to decrease the interval from first concern to diagnosis. In this paper, we present the results of a primary care ASD diagnosis program in which the PCP serves as the primary diagnostician and leverages the infrastructure of the primary care medical home to support the child and family during the pre- and post-diagnostic periods, along with data on parental satisfaction with this model.

METHODS

Retrospective data from a cohort of patients evaluated through this program were analyzed to determine the mean age at diagnosis and interval from referral for evaluation to diagnosis. We used survey methodology to obtain data from parents regarding their satisfaction with the process.

RESULTS

Data from 8 of 20 children evaluated from April 2021 through May 2022 showed a median age of diagnosis of 34.5 months compared to the national average of 49 months. Mean interval from referral for evaluation to diagnosis was 3.5 months. Parental survey responses indicated high satisfaction.

CONCLUSIONS

This model was successful in shortening the interval from referral to diagnosis resulting in significant decrease of age at diagnosis compared with the national average. Widespread implementation could improve access to timely diagnostic services and improve outcomes for children with ASD.

Early detection of neurodevelopmental disorders in African children living in informal settlements in Nairobi

BACKGROUND

Children in low-income and middle-income countries (LMICs) are at a substantially increased risk of delayed physical, emotional and sociocognitive outcomes, with consequential neurodevelopmental disorders. Evidence based, cost-effective and culturally appropriate screening tools are recommended for early identification of developmental disorders.

METHODS

The present study aims to assess the feasibility of early screening for neurodevelopmental disorders in children living in informal settlements in Nairobi, Kenya (Korogocho). The selected tools (ie, the CDC checklist and the Modified Checklist for Autism in Toddlers, Revised (M-CHAT-R)), widely used in high-income countries, are applied in two different populations: one from Kenya (LMIC) and one from Italy, to compare the different scores.

RESULTS

Of 509 children screened, 8.6% were classified at-risk based on the results of the screening tools. Significant risk factors are history of low birth weight and Apgar score, presence of neurological disorders, malnutrition and/or rickets, younger age of the child and older age of the mother. Caesarean section delivery, first pregnancy and mothers' older age were common risk factors among the Kenyan and the Italian samples. The Italian sample had a significantly greater rate of missed milestones.

CONCLUSIONS

Our data demonstrate the feasibility of using the CDC and M-CHAT-R tools in informal settlement dwellers. Further studies are needed to explore the opportunity for early diagnosis of developmental disorders in LMICs.

Identifying Needs of Ethiopian and Eritrean American Parents of Autistic Children

Collectively, Ethiopians and Eritreans represent one of the largest African immigrant groups in the US, yet no research to date exists on families from these communities raising autistic children. The purpose of our study was to examine the experiences of Ethiopian and Eritrean families of autistic children including experiences (1) receiving the autism diagnosis and interacting with healthcare providers, (2) obtaining services and supports for children (including satisfaction with services and barriers to care), and (3) accessing services and supports for caregivers and families (including needs and barriers to care). Ethiopian and Eritrean parents (N = 51) raising autistic children in the US completed an online survey. Parents reported limited prior knowledge of autism within their communities and had varied experiences with healthcare providers through the diagnostic process. They endorsed barriers to accessing care for their child and family supports (such as provider shortages and cost of services), service needs, and dissatisfaction with school-based and behavioral supports. Many parents reported a negative impact on workforce participation in order to meet their child's needs. Parents identified needs that would benefit their autistic children and families, such as accessible support groups to obtain relevant information. To our knowledge, this is the first systematic study exploring the experiences of Ethiopian and Eritrean families raising autistic children in the US. We discuss implications of our findings and recommendations for culturally responsive care.
