Data from the longitudinal Berkeley Becoming a Family Project were used to evaluate the possibility that husbands' and wives' working models of attachment are related to the quality of their marital relationship. The main issue investigated was that of whether there are connections between working models of childhood attachment relationships and the quality of intimate couple relationships. A total of 27 couples were assessed by means of Main's Adult Attachment Interview (AAI), which consists of questions about childhood attachment experiences, and two Self-Report Measures of Relationship Satisfaction, one dealing with marital satisfaction and the other with satisfaction with the couple's communication. Couples were observed with their preschool children in a laboratory family interaction situation. Results revealed that AAI classifications were associated with observations of couple interaction but not with self-reports of relationship satisfaction. Also, men rated as insecure on the AAI were more likely to be part of couples who engaged in conflictual and less positive interactions than were men rated as secure. Women did not exhibit the same tendencies. Insecure women with insecure husbands were more likely to be in couples in which there was more observed conflict and less postive interactions than were insecure women with secure husbands. Included are 11 references and 2 figures. (SAK)
