Parent-infant interaction in the NICU: Challenges in measurement

Abstract

BackgroundParent-infant interaction is poorly understood among high-risk dyads in NICU settings. No parent-infant interaction measures are specifically designed for preterm infants within the NICU nor account for the education NICU parents receive to tailor their interactions based on the infant's cues. AimTo improve our understanding of a measure of parent-infant interaction in the NICU, we investigated relationships between parent-infant interaction scores on the Nursing Child Assessment Feeding Scale (NCAFS) and 1) socio-demographic and medical factors, 2) parent mental health and confidence, and 3) enhanced parental education (delivered as part of the Supporting and Enhancing NICU Sensory Experiences program) on tailoring interactions based on the infant's cues. MethodTwenty-six preterm infants (born ≤32 weeks) had a video recorded oral feeding conducted by a parent in the NICU when the infant was 34–48 weeks postmenstrual age. A certified evaluator scored parent-infant interaction from the videos using the NCAFS. ResultsSeventeen (65 %) parent-infant dyads scored below the 10th percentile on the total NCAFS score. Despite it being well-understood that parent-infant interaction is related to sociodemographic factors and parental mental health, there were no relationships between these factors and NCAFS scores in this study. Dyads who received enhanced parent education (n = 15) had lower NCAFS scores than dyads receiving usual care (n = 11) (p = 0.01). ConclusionIt remains unclear if the standard measure of parent-infant interaction, NCAFS, captured positive and negative interactions in context of assessment of a high-risk dyad within the NICU setting. The utility of the NCAFS with preterm infants in the NICU was not supported by this study.
