The Early Intervention Parenting Partnerships (EIPP) program is a home visiting program that provides home visits, group services, assessments and screenings, and referrals delivered by a multidisciplinary team to expectant parents and families with infants who experience socioeconomic barriers, emotional and behavioral health challenges, or other stressors. The present study examines whether EIPP successfully meets its aims of screening families for social and environmental factors that may increase the risk of children's developmental delays and connect them to the larger statewide early intervention (EI) system relative to families with similar background characteristics who do not receive EIPP. Coarsened exact matching was used to match EIPP participants who enrolled between 2013 and 2017 to a comparison group of families identified from birth certificates. Primary study outcomes including EI referrals, evaluations, and service receipt for children from 3 months to 3 years were measured using EI program data. Secondary outcomes included EI referral source, EI eligibility criteria (e.g., presence of biological, social, or environmental factors that may increase later risk for developmental delay), and information on service use. Impacts were assessed by fitting weighted regression models adjusted for preterm birth and maternal depression and substance use. EIPP participants were more likely than the comparison group to be referred to, evaluated for, and receive EI services. EIPP facilitated the identification of EI-eligible children who are at risk for developmental delays due to social or environmental factors, such as violence and substance use in the home, child protective services involvement, high levels of parenting stress, and parent chronic illness or disability. EIPP serves as an entry point into the EI system, helping families attain the comprehensive supports they may need to optimize their well-being and enhance children's development.
