Determinants of mother-infant interaction in adolescent mothers.

Mother-infant interactions of adolescent and nonadolescent mothers are compared, and the impact of maternal age, ego development, education, and child care support on these interactions is examined. Thirty primiparous, white, lower- to middle-class mothers (half less than or equal to 17 years) and their healthy full-term infants (8 months) were studied. Interactions were videotaped during face-to-face interactions and teaching sessions. Child care support and ego development were assessed. During face-to-face interactions, only one difference was found between adolescent and nonadolescent mothers: nonadolescent mothers showed more positive affect toward infants. During teaching, nonadolescent mothers talked more, showed more positive affect toward infants, and demonstrated tasks more often. Individual differences during face-to-face interactions were more related to mothers' ego development and support whereas teaching interactions were mostly associated with maternal age. Thus, maternal age was a stronger predictor of interactive style during teaching. This may partially explain noted cognitive deficits in infants of teenage mothers. However, individual differences among all mothers in ego development, education, and support were significantly related to interactions. Thus, teenage mothers with less education and support and lower ego development may represent a higher risk subgroup of adolescent mothers providing less optimal care-giving environments for their infants.
