Summary
Many families place their children in care outside of the home during early childhood. As such, it is important to know the long-term effects of such care. In this study, 958 families were followed over a period of 15 years, giving researchers the opportunity to examine the relationship between childcare during early childhood and youth functioning at age 15. There were significant relationships between type and amount of childcare and outcomes at age 15.
Key Findings
Higher quality care at 4.5 years of age predicted greater cognitive-academic achievement at age 15 years.
Childcare in early childhood was associated with increased functioning in middle childhood, which in turn predicted increased functioning in adolescence.
A greater number of hours in childcare during early childhood was associated with more risk-taking and greater impulsivity at age 15 years, though this relationship was mitigated by the experience of high-quality childcare.
Implications for Military Professionals
Support military families in their selection of high quality child care to maximize positive outcomes given that their child care needs may be different given the demands of their job
Assist military parents in managing complex, sometimes fluctuating work schedules in an effort to help Service members and their partners balance their military responsibilities with family life
Implications for Program Leaders
Offer activities for children that build skills in managing strong emotions and decreasing impulsivity
Pair new childcare staff with experienced ones to offer opportunities for mentoring
Implications for Policy Makers
Recommend use of a standardized accreditation system for childcare centers that rates care quality
Encourage limiting the teacher to child ratio in childcare programs
Methods
Women were recruited from a hospital, completed an interview within a month of their child’s birth, and then completed further interviews and testing over the course of the child’s life until age 15 years.
Researchers measured cognitive abilities, risk taking, impulsivity, and externalizing behaviors. Parents reported childcare usage until child's age was 4.5 years. Observational assessments of childcare quality were conducted.
Data were analyzed to determine associations between childcare before the child was 4.5 years old and outcomes at age 15 years.
Participants
Participants were 958 youth who had been followed over a period of 15 years (since birth).
Among the mothers, 26% had no more than a high school education and 21% of families had incomes that were no greater than 200% of the poverty level at the time of the child’s birth.
Of the participants, 76% were White, 13% were Black, and 6% were Latino.
Limitations
All participants were English speaking and did not move in the first three years of the study; this sample may not be representative of all families.
The study is correlational, which does not allow for conclusions about causation.
Participants who dropped out of the study differed slightly from those who remained in the study, so the results may be skewed due to those differences.
Avenues for Future Research
Focus on children of military families to understand the most important factors in providing quality childcare within that population
Examine the effects of peer interaction that occurs in early childhood care centers
Follow children over a longer period of time to examine possible changes in these effects as the child grows into adulthood
Design Rating
3 Stars - There are few flaws in the study design or research sample. The flaws that are present are minor and have no effect on the ability to draw conclusions from the data.
Methods Rating
3 Stars - The definitions and measurement of variables is done thoroughly and without any bias and conclusions are drawn directly from the analyses performed.
Limitations Rating
3 Stars - There are only minor factors that limit the ability to extend the results to an entire population.

Abstract
Relations between nonrelative child care (birth to 4½ years) and functioning at age 15 were examined(N = 1,364). Both quality and quantity of child care were linked to adolescent functioning. Effects were similarin size as those observed at younger ages. Higher quality care predicted higher cognitive–academic achieve-ment at age 15, with escalating positive effects at higher levels of quality. The association between quality andachievement was mediated, in part, by earlier child-care effects on achievement. High-quality early child carealso predicted youth reports of less externalizing behavior. More hours of nonrelative care predicted greaterrisk taking and impulsivity at age 15, relations that were partially mediated by earlier child-care effects onexternalizing behaviors.
