Offspring of women with nonorganic psychosis: antecedents of anxious attachment to the mother at one year of age.

Mother-infant interaction characteristics at six ages during the first year of life were studied in relationship to the development of the infant's anxious vs. secure attachment to the mother at 1 year of age. The same antecedent maternal characteristics, notably less harmony during feeding and less consideration for the child's needs in play, were associated with anxious attachment in both index and control groups. In contrast, control infants' behaviors were totally unrelated to the development of anxious attachment, while index infants developing anxious attachment evidenced reduced social contact toward the mother and increased crying prior to 1 year, suggesting either vulnerability to negative maternal influence or initial deviations in these index offspring.
