An investigation of the relationship between maternal-infant patterns of synchrony during feeding, preterm infant state and a parent administered state modulation treatment
The specific purpose of the study was to consider maternal-preterm infant interaction patterns in the early post hospital discharge weeks given a parent administered prefeeding infant state modulation treatment (PASMT). Twenty mother-preterm infant dyads were enrolled in the study post hospital discharge. The study utilized each dyad as their own control in a pretest/post-test design. Therefore, all mothers received instruction in the PASMT intervention. Demographic data and baseline knowledge of infant behavior was obtained by interview, followed by a baseline observation of a feeding interaction by a maternal and an infant coder in the home setting. The maternal observer coded maternal interventions of arouse, soothe, neutral, or other; infant position; and scored the Nursing Child Assessment Feeding Scales (NCAFS). The infant observer, in time synchrony (15-second epochs) with the maternal coder, coded infant state and quality of sucking. In a subsequent home visit the investigator provided the mother with instruction and written materials on preterm infant state related behaviors and a simple state modulation treatment which included strategies for arousing and soothing their infants prior to and during the feeding episode. After a home visit follow-up on the PASMT instruction, a second feeding observation was made in the home setting by the coding team. Analysis of the data focused on analyses of frequencies of infant and maternal variables coded during baseline and post PASMT instruction observations of feeding interactions. NCAFS total scores at baseline and post PASMT instruction observations were compiled for hypotheses testing. Significant differences demonstrated post instruction included: increased frequency of maternal arousal techniques utilized, increased Maternal Indices of Synchrony, decreased Infant Indices of Need for State Modulation, increased infant alert time, decreased infant drowsy and low state arousal time, increased frequency of sucking bursts, increased length of sustained sucking, decrease in length of feeding time, and increase in total NCAFS scores. Since each dyad served as their own control, the influence of infant maturation on the natural known treatment improvement in mothers' skills could not be evaluated in this study. However, the results are similar to other control/experimental study samples on the NCAFS scores.
