Although self-reports from individual family members regarding their relationship patterns have been used to assess dysfunctional family processes, researchers often rely upon one family member as the source of such information. A study was undertaken to examine the relationship between mothers', fathers', adolescents', and observers' ratings of family affect, conflict, and dominance. Subjects included 151 intact and 114 father-absent families with a delinquent (N=135) or a normal (N=130) adolescent. Each family member completed the Family Relationship Questionnaire, providing individual ratings of the affect, conflict, and dominance for each family dyad. Observer ratings of these variables were obtained from audiotapes of family members jointly discussing and completing the Unrevealed Differences Questionnaire. The results revealed low to moderate agreement between the ratings of different family members, while there was very low agreement between the ratings of individual family members and observers. There were not substantial differences between members of delinquent and normal families in their agreement about family relations. The differences that did emerge between families with delinquent and families with normal adolescents indicated that mothers and fathers of normal adolescents showed more agreement about their affective relations with the adolescent than did mothers and fathers of delinquent adolescents. The findings suggest that it may be preferable to include multiple vantage points in studies of family relations to better represent the complex nature of intrafamily behavior. (NRB)
