The stability of adult attachment and transmission of attachment across 3 generations were examined in a longitudinal study of 96 infants, their mothers, and maternal grandmothers. The study found that mothers' Adult Attachment Interview (AAI) classifications were stable over 12 months in 90% of mothers and 73% of grandmothers, using the AAI's 3-category classification system.

The development of maternal representations of the child during pregnancy guides a mother's thoughts, feelings, and behavior toward her child. The association between prenatal representations, particularly those that are disrupted, and toddler social-emotional functioning is not well understood. The present study examined associations between disrupted prenatal representations and toddler social-emotional functioning and to test disrupted maternal behavior as a mediator of this association. Data were drawn from 109 women from a larger prospective longitudinal study (N=120) of women and their young children. Prenatal disrupted maternal representations were assessed using the Working Model of the Child Interview disrupted coding scheme, while disrupted maternal behavior was coded 12-months postpartum from mother-infant interactions. Mother-reported toddler social-emotional functioning was assessed at ages 12 and 24 months. Disrupted prenatal representations significantly predicted poorer toddler social-emotional functioning at 24 months, controlling for functioning at 12 months. Further, disrupted maternal behavior mediated the relation between disrupted prenatal representations and toddler social-emotional problems. Screening for disrupted representations during pregnancy is needed to facilitate referrals to early intervention and decrease the likelihood of toddler social-emotional problems.

Data from a multi-method, longitudinal study involving a community sample (N = 120) of pregnant women aged 18–42 were used to examine disrupted maternal representations of the child as a mechanism of the transmission of trauma from mother to infant. Using structural equation modeling, the best fitting model indicated that severity of mothers' childhood interpersonal trauma was associated with severity of disruption in prenatal representations of the child, which in turn was associated with less secure infant-mother attachment at 1 year of age. There was a significant indirect effect of maternal childhood interpersonal trauma on infant-mother attachment insecurity via disrupted prenatal maternal representations. Findings highlight an important mechanism of trauma transmission that could be targeted in interventions with mother-infant dyads. [ABSTRACT FROM AUTHOR]

Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation. Therefore, the authors explored sensitivity as a moderator, studying the (a) interaction of mental representation and sensitivity as it predicts infant attachment security and (b) level of sensitivity in mothers whose infants' attachment security is either concordant or discordant with their own. The interactional analyses were not significant. But the match-mismatch data showed that when mother-infant attachment strategies were discordant maternal sensitivity was more consistent with infant than maternal attachment strategy. These findings are congruent with an interpretation of sensitivity as a moderator that can block transmission of attachment strategy.

Mothers' representations and their infants are assessed prenatally to determine the stability and association with infants' attachment classifications. The study used the Working Model of the Child Interview (WMCI) where mothers' representations of their infants were assessed prenatally while the infant Strange Situation attachment classifications was also examined. Results gathered by the WMCI show problems in skewed distribution of the sample.
