Evaluative communications between affectively ill and well mothers and their children.

Earlier research suggests that the natural verbal discourse of mothers with their children can be important in clarifying, verifying, and evaluating the behavior in which a child is engaged, in attributing qualities to the child, and in influencing the child's self-perceptions. We investigated the potential influences of parental affective illness (bipolar affective disorder and unipolar depression in contrast to no history of psychiatric illness) on such "labeling" behavior in a sample of 61 mothers and their older (school-age) and younger (preschool-age) children. It was hypothesized that the dispositions characterizing affective illness (specifically, negativity and disengagement) would be reflected in the labeling statements of mothers with a diagnosis as they interacted with their children. Based on videotaped interactions during a visit to a home-like laboratory apartment, labeling statements were identified in terms of speaker and person being labeled ("addressee") and coded (positive, negative, mixed, or neutral) for judgmental and affective quality of the statement and reaction of the addressee. Data were analyzed (a) by family unit and (b) my mother to child statements. The general pattern of findings indicated, in relative terms, an excess of negativity on the part of family members in the bipolar group and a dearth of negative affect for mothers in the unipolar group. Negativity in the bipolar group appeared to be especially likely when the setting involved mothers and two male children. Additionally, findings are discussed in terms of sex differences in vulnerability to depression.
