RESUMO
The authors performed a randomized, controlled trial to assess the impact of the Video Interaction Project (VIP), a program based in pediatric primary care in which videotaped interactions are used by child development specialists to promote early child development. Ninety-three Latino children (51 VIP, 42 control) at risk of developmental delay on the basis of poverty and low maternal education (none had completed high school) were assessed for cognitive and language development at age 21 months. Results differed depending on the level of maternal education; the VIP was found to have a moderate impact on children whose mothers had between seventh and 11th grade education (approximately 0.75 SD for cognitive development, 0.5 SD for expressive language) but little impact on children whose mothers had sixth grade or lower education.
