Relationships between attachment behavior in the laboratory and the caretaking environment

How useful are observations of patterns of attachment behavior in a structured laboratory setting for making inferences about the quality of caretaking received by an infant in the home environment? To address this question a sample of 107 12-month-old infants who had participated in a longitudinal intervention project beginning before birth through 14 months of age were observed in a structured laboratory setting. Patterns of attachment behavior were compared to maternal caretaking variables observed in the home environment as well as to ratings of the quality of the infants' play. The results indicated that attachment behavior in the laboratory can be used to make inferences about the quality of caretaking in the home environment with confidence when a consistent and unambiguous pattern of either optimal or problematical attachment behavior is present, but not when the attachment behavior pattern is inconsistent or ambiguous.
