Early Intervention Service Intensity and Change in Children's Functional Capabilities.

Objective: To estimate correlates of early intervention (EI) service dosage and gains in children's functional capabilities from EI entry and discharge.

Design: Retrospective cohort study.

Setting: Secondary analyses of a subset of data (N=1005) collected from an EI administrative database on children discharged from a large, urban EI program between October 1, 2014 and September 30, 2016.

Social and Functional Characteristics of Receipt and Service Use Intensity of Core Early Intervention Services.

Objective: Describe children's diagnostic, social, and functional characteristics associated with the use of core early intervention (EI) services.

Methods: The sample included infants and toddlers (N = 2045) discharged from an urban EI program (2014-2016). Adjusted logit models estimated the marginal effects and 95% confidence intervals (CIs) of receipt of any of the 4 core EI services, controlling for the child's developmental condition type, race and ethnicity, primary language, sex, insurance type, age at referral, and functional performance at EI entry.
