Relationship between service receipt during the COVID-19 pandemic and autistic children's multisystem outcomes and...

Children with autism spectrum disorder (ASD) display a variety of core and co-occurring difficulties in social, communication, everyday functioning, cognitive, motor, and language domains. Receiving a combination of services to accommodate needs of autistic individuals is essential for improving their future outcomes. During the COVID-19 pandemic, reduced service access negatively impacted autistic children's outcomes. This study aimed to examine the relationship between service receipt and parental perceived outcomes in autistic children while accounting for various demographic, child, and parental factors. We utilized parental COVID-19 impact survey data from the SPARK study (N = 6067). Ordinal logistic regression analyses were used to predict perceived child outcomes. Demographic, child, and parental factors were included in the prediction models. Service receipt of SLT, ABA, PT/OT, MED, and MH were associated with perceived child outcomes. PT/OT and ABA predicted improvements in domains of social interaction, everyday activity, and overall autism severity; SLT and ABA contributed to improved perceived communication outcomes. Receiving MH and MED services was associated with worsening of perceived outcomes on all domains. Younger age, males, higher family income, lower autism severity, lower motor, function, and cognitive delay, greater language delay, and the absence of parental mental health issues were associated with greater improvements in various perceived outcomes. Overall, PT/OT and ABA services are associated with improved perceived social and functional outcomes whereas SLT and ABA services are associated with improved perceived communication outcomes. We also provide a wholistic view of factors affecting relationships between service receipt and perceived child outcomes during the pandemic.
