| Abstract: | The construction of developmentally appropriate and valid assessments is central to the study of attachment relationships beyond infancy. A common procedure has been that of validating new measures for older children against strange situation classifications obtained in infancy. Although reasonable, a key criterion against which to validate new measures should include concurrent secure base behavior in naturalistic settings. The purpose of this study was to investigate whether three‐year‐olds' (N = 45) ability to use their mother as a secure base at home was related to their strange situation classifications when using the MacArthur classification system. Behavior in the strange situation was coded by two experts, and independent observers described secure base behavior at home with the attachment Q‐Set. Results indicated that strange situation classifications were not related to either global q‐set security scores or specific scale scores that reflect the quality of child–mother interactions at home. |
