The Infant Health and Development Program is a two-generation early education model designed to improve parenting competence and child well-being. As part of an 8-site randomized clinical trial involving low birthweight premature children, assessments of children and parents were gathered at the time of program completion (age 3), with follow-up at ages 5, 8, and 18. Two key parenting processes were assessed at age 18 based on theory stipulating the centrality of parenting to long-term development in children. Analyses based on 283 control group and 178 Infant Health and Development Program treatment group participants revealed that treatment group mothers scored higher on one, the provision of enriching experiences. Evidence of sustained impacts on parenting suggests that carefully structured two-generation early education programs may prove good investments for promoting competence and adaptive functioning in high-risk children.
