COVID-19 Pandemic Impacts on Behavioral and Emotional Health of Young Children With Autism.

Objective: To test initial hypotheses that the coronavirus disease 2019 (COVID-19) pandemic was associated with decreases in adaptive behavior and increases in behavioral and emotional problems of children with autism; greater impacts for children who lost specialty services; and greater behavioral and emotional problems for children with autism vs control participants. Method: Eligible participants (N = 1,158) enrolled in phase 3 of the multisite, case-control Study to Explore Early Development (SEED) before March 31, 2020, were between 2 and 5 years old, and completed follow-up assessments between January and July 2021. Caregivers completed a COVID-19 Impact Assessment Questionnaire, Vineland Adaptive Behavior Scales (VABS), and Child Behavior Checklist (CBCL) for 274 children with autism and 385 control participants. Results: Mean VABS communication scores of children with autism decreased significantly (mean difference [SD] = -4.2 [10.5]) between prepandemic and pandemic periods, while VABS composite (+2.0 [9.0]), daily living (+5.5 [11.4]), socialization (+2.3 [10.0]), and CBCL (-3.2 [8.4]) scores improved. In contrast, CBCL scores worsened in population control participants (+3.4 [8.8]). Children with autism who missed specialty appointments scored significantly lower on VABS during the pandemic vs children who did not miss appointments (VABS Composite 70.6; 95% CI 68.8-72.4 vs 74.5; 95% CI 71.8-77.2). Conclusion: While stay-at-home policies of the COVID-19 pandemic may have beneficially impacted daily living skills, socialization, and behavioral and emotional well-being of children with autism, benefits may have occurred at the cost of communication skills. These findings indicate the need for strategies to maintain therapeutic services in future emergency settings.
