Disorganized attachment behavior in infancy: Short-term stability, maternal and infant correlates, and risk-related subtypes

Abstract

AbstractThis study of 71 low-income mothers and infants examined whether the disorganized/disoriented (D) infant attachment classification is best viewed as a single category or whether at least two subgroups exist, corresponding to the forced-secure and forced-insecure alternate classifications. Correlates of the D classification as a whole, and of the two subtypes of disorganized behavior, were examined in five domains, including 6-month stability, maternal childhood history of loss, severity of maternal psychosocial risk, maternal behavior toward the infant at home, and infant mental development. Results indicated that the two subtypes of disorganized infant attachment behavior differed in age of emergence, maternal childhood history, severity of associated family risk factors, and the extent of the mother's lack of involvement with the infant at home. Across both D subtypes, disorganization of attachment strategies was associated with less optimal maternal behavior at home and with decreased mental development scores at 18 months. Results are discussed in relation to Main and Hesse's (1990) theory of the role of fear-inducing parental behavior in the genesis of disorganized infant attachment behavior and in relation to Aber, Allen, Carlson, and Cicchetti's (1989) concept of secure readiness to learn.
