New insight on intergenerational attachment from a relationship-based analysis.

Research on attachment transmission has focused on variable-centered analyses, where hypotheses are tested by examining linear associations between variables. The purpose of this study was to apply a relationship-centered approach to data analysis, where adult states of mind, maternal sensitivity, and infant attachment were conceived as being three components of a single, intergenerational relationship. These variables were assessed in 90 adolescent and 99 adult mother-infant dyads when infants were 12 months old. Initial variable-centered analyses replicated the frequently observed associations between these three core attachment variables. Relationship-based, latent class analyses then revealed that the most common pattern among young mother dyads featured maternal unresolved trauma, insensitive interactive behavior, and disorganized infant attachment (61%), whereas the most prevalent adult mother dyad relationship pattern involved maternal autonomy, sensitive maternal behavior, and secure infant attachment (59%). Three less prevalent relationship patterns were also observed. Moderation analyses revealed that the adolescent-adult mother distinction differentiated between secure and disorganized intergenerational relationship patterns, whereas experience of traumatic events distinguished between disorganized and avoidant patterns. Finally, socioeconomic status distinguished between avoidant and secure patterns. Results emphasize the value of a relationship-based approach, adding an angle of understanding to the study of attachment transmission.

Understanding sensitivity: lessons learned from the legacy of Mary Ainsworth.

On the basis of extensive home observations, Ainsworth proposed that a mother's sensitivity to her infant's signals is the primary determinant of attachment security. Although subsequent research has found a relationship between sensitivity and attachment security, the effect sizes are much smaller than those reported by Ainsworth. In addition to the amount of observation time that might account for the effect size difference, we consider Ainsworth's focus on understanding the organizational structure of relationships. We coded 30 minute video records of interactions between 64 mother-infant dyads from semi-structured home observations conducted at 10 months of age. Coding consisted of writing a narrative summary of the interactions, annotating a completion of Ainsworth's rating scales of acceptance, accessibility, cooperation and sensitivity and then describing the mother's behavior using the Maternal Behaviour Q-set. Sensitivity scores derived from the Q-sort descriptions were robustly related (r = .65) to secure-insecure classifications in the Strange Situation conducted at 13 months. We reflect on the process of assessing Ainsworth's construct of sensitivity.

Understanding the transmission of attachment using variable- and relationship-centered approaches.

The interrelations of maternal attachment representations, mother-infant interaction in the home, and attachment relationships were studied in 99 adolescent mothers and their 12-month-old infants. A q-factor analysis was used to identify emergent profiles of mother and infant interaction. Traditional multivariate statistical analyses were complemented by a relationship-based approach utilizing latent class analysis. The results confirmed many theoretical predictions linking interaction with autonomous maternal representations and secure attachment, but failed to support a mediating role for maternal sensitivity. Strong associations were found between mothers displaying nonsensitive and disengaged interaction profiles, infants who did not interact harmoniously with the mother and preferred interaction with the visitor, unresolved maternal representations, and disorganized attachment relationships. Moreover, maternal nonsensitive and disengaged interaction in the home mediated the association between unresolved representations and disorganization. The results of the latent class analysis were consistent with these findings and revealed additional, empirically derived associations between attachment classifications and patterns of interactive behavior, some of which prompt a reconsideration of our current understanding of attachment transmission in at-risk populations.

Maternal emotional responses to preterm birth.

Mothers of 144 preterm infants with varying degrees of neonatal illness were interviewed prior to their infants' discharge from neonatal intensive care. Their major concerns were for the infants' survival rather than their own welfare. Husbands, parents, and, for members, church were seen as the major sources of support.
