Transmission of attachment across three generations

A low-risk Finnish sample (Ntotal=135) of parents expecting their first child and maternal grandmothers was followed from pregnancy until the child was 3 years old. The Adult Attachment Interview (AAI) was used to assess attachment in mothers during the last trimester of pregnancy, and maternal grandmothers. The Strange Situation Procedure (SSP) was used to assess attachment in infants at 12 months, and the Preschool Assessment of Attachment (PAA) at 3 years. Mothers' AAI classifications (3-category) during pregnancy predicted infants' SSP classifications (3-category) in 76% of cases, and the 3-year-old children's PAA classifications (3-category) in 58% of cases. Grandmothers' AAI classifications predicted infants' SSP classifications in 48% of cases, but the 3-year-old children's PAA classifications in 72% of cases. Using log-linear analysis, it was shown that a simple model accounted for transmission of attachment across three generations when the children were 3 years. Even though the results indicated continuity across generations, the correspondences were slightly weaker than those obtained by Benoit and Parker in their 3-generational study. The results are discussed in terms of the prototype view, the rapid contextual changes seen across 3 generations in Finland, the size of the sample, and the comparability of the DMM to other assessment methods of attachment.
