Impacts of a Parent-Implemented Language Intervention on Children's Language Development Within Home Visiting

The purpose of this study was to conduct a pilot randomized controlled trial to evaluate the efficacy of an intervention for enhancing the language development of young children enrolled in home visiting programs. The participants were 59 children (18–30 months old) enrolled in one of three types of home visiting programs. Children's language skills were assessed pre- and post-intervention with the Preschool Language Scale. To estimate the impacts of the intervention on children's language scores, we conducted a two-level hierarchical linear model. Results from this model provide promising evidence for the benefits of using systematic parent-implemented language interventions.
