PURPOSE: The purpose of this study was to test a coding system, the Maternal-Infant Synchrony Scale (MISS), for assessing synchrony of feeding interaction between a mother and her preterm infant. The secondary aim was to describe mother and preterm infant synchrony during feeding and the change over time. METHODS: A descriptive, longitudinal design using data collected during an earlier study was employed, using a sample dataset from 10 mother-infant dyads that completed three data collection points. The Noldus Observer XT 8.0 (Noldus Information Technology b.v., 2006) was used for data review and coding. The MISS was created from pilot data and definitions further refined. The frequency of occurrence for select behaviors and the percentage of time behaviors occurred during the feeding and the changes in behaviors over the three observations periods were calculated. RESULTS: The synchrony tool developed in this study demonstrates that changes occur in mother and infant behavior over time. Mothers were attentive and focused during feedings and monitored their infants' sucking intently but there was little interaction between the dyad. Infant attempts at interaction were greater than the mother attempts to engage her infant. The influence of infant maturation on feeding behaviors was evident across observations. CONCLUSION: This study revealed behaviors that are descriptive of the interaction and can be used to develop interventions that would support the developing relationship. Use of the MISS with a larger sample size and a cohort of healthy, term newborns is needed to establish the MISS as a valid and reliable measure of synchrony.
