ABSTRACT
This study examined affective/communicative patterns in the interactions of unipolar, bipolar, and well mothers with their preadolescent and adolescent children. As part of a large longitudinal project, mother-child interaction was assessed for two siblings ages 8 to 11 and 12 to 16. Interactional difficulties were linked to both maternal affective illness and child problem status. Preadolescent children appeared more comfortable/happy with well mothers than with affectively ill mothers. Mothers and their preadolescents were more critical/irritable with each other when the child had a psychiatric disorder. Gender differences were apparent, particularly in regard to mother's current psychiatric status. Interactions in adolescent-daughter dyads were more critical when mothers met criteria for a major depressive episode within the month. The results illuminate interactive processes through which psychopathology may be perpetuated in families.
