Severe maternal psychopathology and infant-mother attachment

Eighty-two mother-infant dyads, comprising women with psychiatric disorder and individually matched controls, were followed up over the children's 1st year of life. The mothers with mental illness consisted of two subgroups: first, 25 severely mentally ill mothers who had been admitted to a psychiat ric unit with their infants; and second, 16 mothers from a community sample meeting research diagnostic criteria for unipolar, nonpsychotic depression . With the exception of six dyads in the in-patient group, observations wer e made of the mother-infant interaction and the quality of the infant-mothe r attachment relationship at 12 months. The: nature and course of the mothe rs' illness was also documented. Although few residual symptoms of maternal mental illness were detected at 1 year postpartum, interactional disturban ces were evident among the case group dyads. A strong association was revea led between infant-mother attachment quality and maternal diagnosis: a mani c episode of illness in the postpartum period was related to security in th e attachment relationship, and psychotic or nonpsychotic depression was rel ated to insecurity. Concurrent patterns of mother-infant interaction provid ed support for this finding.
