Leveraging the universal newborn hearing screen to impact parental knowledge of childhood speech development in low socioeconomic populations: A randomized clinical trial.

Objective: To determine the impact of a video intervention administered at the time of the universal newborn hearing screen on caregiver knowledge of infant cognitive and language development in low socioeconomic status English-speaking parents.

Methods: A parallel-group, single-blind randomized clinical trial was conducted from April to August 2016. Eligible participants were at least 18 years, delivered a singleton neonate, English speaking, and designated as low socioeconomic status based on household income and level of education.

Educating Parents About Infant Language Development: A Randomized Controlled Trial.

A total of 427 women (aged 18-45 years) who delivered a singleton neonate without serious medical complications were randomized to watch either an educational intervention (n = 225) or the sudden infant death syndrome (n = 202) video. Linear mixed models showed that the intervention women significantly gained knowledge over time. Knowledge gain was largest among high-socioeconomic status (high-SES) and middle-SES English-speaking, smaller among low-SES Spanish-speaking, and nonsignificant among low-SES English-speaking women.
