Comparing the Implementation Context for Early Intervention Services Before and During the COVID-19 Pandemic.

The COVID-19 pandemic not only led to drastic changes in the implementation context for early intervention and early childhood special education services in 2020, but has had an enduring effect on the organizations, educators, families, and children with developmental delays and disorders. Through secondary data analysis, characteristics of toddlers with autism being served in a publicly funded center-based early intervention program as well as the characteristics of their educators are examined, comparing those who were enrolled in (a) two randomized trials conducted prior to the pandemic and (b) one ongoing randomized trial that launched in return to in-person educational services after the pandemic shutdown. Significant demographic differences are found for toddlers, where the current study includes more girls (p = 0.002), who are younger (p < .001) than the prior studies. Further, toddlers enrolled in the current trial are entering with significantly younger receptive (p < .001) and expressive language age-equivalent scores (p < .001) than toddlers from the prior studies. In addition, significant differences are also found for teaching assistants (TAs), who are younger (p < .001), less experienced supporting children with autism (p < .001), have spent less time in this position (p < .001), and who are still working toward college degrees (p < .001) than TAs in the prior studies. Implications of these changes for both intervention strategies to support the strengths and needs of the toddlers (e.g., reduce frequency of TA-child pairing changes to build rapport, increase time in adult-child JASPER before adding peers) as well as implementation strategies (e.g., increase foundational content, TA teaming) to support the training and retention of the TAs are discussed.
