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.
