In a randomized controlled trial at 12-months of age, the effect of the Mother Infant Transaction Program was tested on social interaction between mothers and moderately and late preterm infants with gestational ageā‰„30.0 and <36 weeks. Ninety-three play sessions were videotaped and coded, 46 mothers-infants in the intervention group and 47 mothers-infants in the control group. The intervention mothers scored higher on maternal sensitivity/responsiveness (p=.05). Being a first-time mother was a moderator that enhanced the effects of the intervention. First-time mothers were more sensitive/responsive to their infant's cues (p=.01), and the dyads evinced higher level of synchrony (p=.02) as compared with experienced mothers. More positive mood was observed among their infants (p=.04). The findings suggest that the intervention contributes to better mother-infant interactions in moderately and late preterm infants of first-time mothers.
