SLIDE 7: SAMPLE RECRUITMENT
Families were recruited during hospital visits with mothers shortly after the birth of a child in 1991 at 10 sites in the U.S. During selected 24-hour intervals, all women giving birth were screened for eligibility. From that group, 1364 families completed a home interview when the infant was 1 month old and became the study participants.
SLIDE 8: SAMPLE DEMOGRAPHICS
The analysis sample for the current study consisted of 872 children. Children were included in these analyses if they had outcome measures collected between 4½ years and Grade 3 and if early child-care quality, hours, and type had been assessed. The sample was balanced in terms of child gender. 18% were poor or near poor. 26% of the mothers had a high school degree or less. 20% of the sample were children of color.
SLIDE 9: OVERVIEW OF DATA COLLECTION
Major assessments were conducted in the home, child care, school, and laboratory settings. These assessments occurred from infancy through Grade 3. They included naturalistic observations in the home, child care, and school settings; semi-structured assessments that were videotaped and scored at a central location; standardized tests of language, cognition, and academic achievement; maternal reports and teacher reports of child functioning.
SLIDE 10: CHILD CARE MEASURES
Nonmaternal child care was defined as regular care by anyone other than the mother—including care by fathers, relatives, and nannies (whether in home or out of home), family daycare providers, and centers—that was routinely scheduled each week.
Mothers reported the study children’s hours of routine nonmaternal care during the phone and personal interviews conducted at 3 to 4 -month intervals (called epochs). The hours spent
