Patterns of Attachment in Two- and Three-Year-Olds in Normal Families and Families with Parental Depression

Abstract

Patterns of attachment were examined in normal and depressed mothers. Mother's diagnosis (bipolar, major unipolar, or minor depression, or no psychiatric disorder), self-reported current mood states, and affective behavior in interaction with the child were considered. A modified version of Ainsworth and Wittig's Strange Situation was used to assess attachment. Insecure (A, C, and A/C patterns) attachments were more common among children of mothers with a major depression (bipolar or unipolar) than among children of mothers with minor depression or among children of normal mothers. Insecure attachment was more frequent in children of mothers with bipolar depression than in children of mothers with unipolar depression. A/C attachments were associated with histories of most severe depression in the mother. In families in which mothers were depressed, depression in the father did not increase the likelihood of anxious attachment between mother and child. However, if mothers with a major affective disorder were without a husband in the household, risk of an insecure mother-child attachment was significantly increased. The mothers' expressed emotions (positive vs. negative) in interaction with their children in situations other than the Strange Situation, and independent of diagnosis, predicted patterns of attachment: mothers of insecurely attached children expressed more negative and less positive emotion. Mothers' self-reports of moods on the days they were observed were unrelated to attachment. Results are discussed in terms of the transmission of social and emotional disorders in relation to mothers' affective functioning.
