The present study addressed whether security of attachment is differentiated by quality of parenting and quantity of exposure to child care. Sixty mothers participated with their 14-month-old infants, who by the age of 12-months had received either exclusive maternal care, or varying degrees of exposure to child care. Levels of attachment security were assessed through maternal completion of the Attachment Q-Set(AQS); parenting quality was assessed through observations of mother-infant interactions during structured tasks. The scores that less sensitive mothers assign their toddlers is higher when their children are in child care for more hours per week; whereas the scores that more sensitive mothers assign their toddlers is lower when their children are in child care for more hours per week. These contrasting patterns suggest that the effects of parenting style on attachment security are moderated by quantity of exposure to child care. Copyright # 2003 John Wiley & Sons, Ltd.
EXPOSURE TO CHILD CARE, PARENTING STYLE AND ATTACHMENT SECURITYIn the past several decades, the increasing number of infants experiencing nonmaternal care has raised questions about child outcomes as a function of early exposure to child care (Barglow et al., 1987;Belsky and Rovine, 1988; Brazelton, 1985). One concern has been the possibility that early non-maternal care poses a challenge to the formation of secure infant-mother attachment relationships. From the vantage point of attachment theory (Ainsworth, 1973;Ainsworth et al., 1978;Bowlby, 1969), maternal behaviors during an infant's first year of life are critical to the formation of a secure attachment relationship. Theorists working from this perspective have been particularly concerned over the early and routine mother-infant separations entailed by child care (Matas et al., 1978;Smith and Pederson, 1988). These concerns received support from several meta-analyses of the relationship between early placement in child care and attachment (Belsky and Rovine, 1988;Clarke-Stewart, 1989;Lamb et al., 1992), and from studies revealing that entrance into child care prior to the age of 12-months is associated
