title: Dyads at risk: methadone-maintained women and their four-month-old infants.
abstract: As part of a longitudinal study of offspring born to substance abusers, we videotaped 17 methadone-exposed and 23 comparison 4-month-old infants interacting with their mothers. Using a scale we developed, we rated communicative functioning in dyadic interaction and related mothers' interactive performance to their psychological and psychosocial resources and infants' interactive performance to their motor functioning as assessed on the Bayley Infant Behavior Record. We found, cutting across drug groups, that mothers who performed poorly on interaction were likely to have poor maternal resources and that infants showing poor communicative functioning were likely to show problematic motor functioning--namely, greater tension and poorer coordination relative to activity level; it was the opposite for mothers or infants who communicated well. Methadone was only one among several risk factors affecting interaction.
