This randomized controlled trial showed that video-based anticipatory guidance implemented at well-child visits in the first 6 months increased knowledge of early cognitive and language development (P < .001), which in turn promoted cognitive growth fostering behaviors among parents of low socioeconomic status (95% CI 0.09-0.57). TRIAL REGISTRATION: ClinicalTrials.gov: NCT02812017.
