Impacts of universal childcare on early behavioral development: evidence from a birth cohort in Québec, Canada.

PURPOSE:To examine associations between universal pre-school childcare use and later behaviors among children at age 6 years. METHODS:Using annual follow-up data of a birth cohort (N=1450), we estimated differences in behavioral scores by primary childcare arrangement between ages 2-5 years - universal subsidized childcare program (CPE care), non-CPE childcare, and parental or family care (no regular care) - using propensity score inverse probability weights. RESULTS:Teachers reported slightly higher levels of hyperactivity (0.73, 95% CI: 0.32, 1.1) and indirect aggression (0.58, 95%CI: 0.24, 0.91) among children who attended a CPE than children in non-CPE care. However, these patterns were not observed from either maternal or paternal reports. Similarly, teachers' assessments of slightly higher physical aggression (0.50, 95% CI: 0.11, 0.88) and opposition (0.63, 95% CI: 0.21, 1.05) scores among children in CPE care than children who did not have a regular childcare were not observed in parental assessments. Behavioral scores by childcare arrangement were similar between girls and boys and across family socioeconomic position. CONCLUSIONS:Universal pre-school childcare does not appear to have substantial impacts on child behaviors at early school age, however teachers rated externalizing behaviors to be slightly higher among children who attended universal childcare.
