Family paradigm theory explains variations in families that are based on their shared beliefs about the social world and their family's place within it. Key concepts of the theory and some of the supporting research are presented. Family rituals provide a window for viewing the family's efforts to maintain this shared concept of family identity. Suggestions for evaluating ritual use in families during times of stress and/or transition are provided. Ritual evaluation may give clues to difficulties families face in maintaining a shared identity during challenging periods of change or conflict.
