In this study, the Adult Attachment Interview (AAI) was applied in The Netherlands, to test certain aspects of its validity, and to provide information about its relation to toddlers' socio-emotional adaptation. In the second year of life, a sample of 80 infants were seen with their father, mother, and professional caregiver in the Strange Situation procedure, and in a free-play situation to assess caregivers' sensitivity. Two years later, 68 children participated in a follow-up study, involving mothers, fathers, and professional caregivers. Parents were interviewed with the AAI, and completed the Parental Bonding Instrument that measures attachment experiences in childhood. Parents also completed the Nijmegen-California Q-sort, to measure their children's ego-resilience and ego-control. Professional caregivers rated children's sociability in pre-school using the Pre-School Behavior Inventory. As predicted the AAI and the Parental Bonding Instrument were related. Only the AAI, however, yielded classifications that corresponded with the quality of infant-parent attachment. Furthermore, AAI classifications for mothers were related to maternal sensitivity: Secure mothers are more sensitive to their daughters than insecure mothers, but for boys this was not true. In addition, AAI classifications for parents were related to their children's socio-emotional development in the pre-school years. Secure mothers have children with more ego-resilience and less ego-undercontrol. Dismissing fathers have children who are rated as more aggressive, less social, and less timid than secure or preoccupied fathers. The AAI appears to be a promising instrument for measuring parental state of mind with respect to attachment relationships in a variety of natural settings.
