Improvement in Cognitive Outcomes for Children Living in Poverty in the Legacy for ChildrenTM Parenting Intervention Five Years Post-Intervention
The Legacy for ChildrenTM (Legacy) group-based parenting model was developed to address developmental disparities associated with childhood poverty. A set of randomized controlled trials of Legacy tested two implementations, prenatal to age 3 (Los Angeles [LA]) and birth to child age 5 (Miami), for their impact on parenting and maternal wellbeing, child development (cognitive, language, socioemotional) and health. Third grade follow-up data were also collected.
Cognitive outcomes from 246 Legacy participants in Miami and 233 participants in LA were analyzed when the children were 3 and 5 years old, and in third grade. These assessments included the Kauffman Assessment Battery for Children-II (KABC) and Woodcock-Johnson III Tests of Achievement (WJ). An intent-to-treat approach was used and t-tests compared unadjusted mean scores of the intervention and comparison groups by site.
In LA, the intervention group scored on average 4 points higher than the comparison group on the KABC at both age 3 years and third grade time points (Age 3: 83.7 vs. 79.3, p=0.02; Third Grade: 94.2 vs. 89.9, p=0.03). The intervention group also scored higher on third grade WJ Letter-Word (103.8 vs. 97.7, p=0.01) and Applied Problems (96.5 vs. 92.3, p=0.04) subtests. There were no statistically significant cognitive differences at the Miami site.
Children of mothers participating in the LA site of Legacy had significantly higher IQ through third grade, five years post intervention. Shifting the developmental trajectory of early cognitive development has immediate and long term implications for child health, educational achievement, and wellbeing.
