Mother–infant behavioral interactions in teenage and adult mothers during the first six months postpartum: Relations with infant development

The purpose of this study was to compare adolescent mothers' (high‐risk group), at‐risk adult mothers' (moderate‐risk group), and no‐risk adult mothers' (low‐risk group) behavioral interactions at one and six months postpartum, and to examine the relationships between maternal behaviors and infant developmental scores on the Bayley scales. Results indicated that high‐risk teenage mothers and moderate‐risk adult mothers vocalized less and had lower contingency rating scores compared to low‐risk adult mothers. Also, infants in the high‐risk and moderate‐risk groups obtained lower mental scores at six months compared to the low‐risk group. Moderate stability across time was found for maternal vocalizations and infant scores on the mental scale. Maternal vocalizations and behavioral contingency rating scores at one month were associated with infants' six‐month performance on the Bayley scales. Specific intervention strategies were discussed with the aim of targeting and improving early maternal behavioral patterns in at‐risk groups. ©2003 Michigan Association for Infant Mental Health.
