This report presents findings from the Cost, Quality, and Outcomes Study, a 5-year, ongoing longitudinal study examining the effects of child care in 4 states. The report focuses on the emergence of the quality of children's early relationships with their teachers in childcare as an important predictor of their social relations with peers as they…

Examined relationships among child-mother attachment when children were age 3; family stress when children were 3, 4, and 5; and social-emotional outcomes in kindergarten. Found that less secure kindergartners were more aggressive and less socially competent than secure peers, and kindergartners who had experienced more family stress in preschool…

Identified predictors of outcomes for 30-month-olds with developmental delays or biomedical risk factors in child care. Found that after accounting for selection effects, child characteristics at 12 months, and home caregiving quality, no child-care variables predicted development or attachment security. Older entry age predicted greater…

Explored within-group effects of mother-infant attachment and day care on children's social and emotional development in a high-risk, low income sample of mothers and infants who entered day care early, and a home-reared, middle-class sample of infants and their mothers. Found that the effects of early day care are influenced by security of…

This study examines parenting in 290 of the 2,322 families studied in the New Chance Demonstration, a national research and demonstration program operated between 1989 and 1992 in 10 states. The demonstration project sought to improve the economic prospects and overall well-being of low-income young mothers (ages 16 to 22) and their children…

This study examined the associations between the early family environment, older siblings' early characteristics, and later sibling relationships. Participating were 37 families with infants and preschool-age older siblings who were observed in the laboratory at 3 time points and followed-up 3 years later. Findings indicated that parents' early…

Examined role of home social relationships as predictors of social functioning in first years of school. Found that the quality of different family relationships provided relatively independent and complementary information about early social functioning in school, with more limited evidence for compensatory or protective processes at work.…

This longitudinal study investigated mother-infant interaction patterns and infant social and emotional development as influenced by maternal and non-maternal infant care and by selected maternal and infant characteristics. Extensive data (including maternal attitude scores, demographic infomration, infant care observations, developmental test…

This is a partial report of a longitudinal investigation designed to assess the psychological effects of an experimentally conducted day care program on children during the first 30 months of life. The experimental subjects were Chinese and Caucasian children from working and middle class families who were cared for at a special group care center…

Children who had been classified at 12 and 18 months of age according to their attachment to mother and father were observed in play groups and given a social perception test at 5 years. Findings suggest that infant-mother attachment is a more powerful predictor of social competence in preschool than is father attachment or combined mother and…

This paper summarizes investigations of school connectedness completed by the Social Development Research Group in two longitudinal studies, the Seattle Social Development Project and Raising Healthy Children. The theoretical importance of school connectedness, empirical support for the theoretical propositions of the impact of school…

During the early 1980s, use of crack cocaine by expectant mothers introduced U.S. schools and social agencies to a large cohort of children with attachment problems, attention and learning difficulties, hyperactivity and other abnormal behaviors. Research focused on the early characteristics and needs of so-called "crack kids," but little…

This year-long study explored toddler separation distress behaviors in a developmentally appropriate classroom that used a gradual entry process, including a home visit. Four toddlers were selected for study: two had overt separation distress behaviors at the beginning of the year, and two did not exhibit overt distress. The children were…

The theoretical work on attachment behavior by John Bowlby and Mary Ainsworth spawned one of the broadest, most creative lines of research in twentieth century psychology. This volume compiles articles discussing attachment theory and research, measurement issues, and contributions of recent theoretical and empirical developments to the study of…
