Turkish adaptation of the Neonatal Eating Assessment Tool-Bottle-Feeding in preterm infants discharged to home.

Background/aim: Preterm infants often continue to have feeding difficulties after hospital discharge. Parental use of assessment tools and collaboration with health professionals are important for the early diagnosis of postdischarge feeding difficulties. This methodological study examined the validity and reliability of the Turkish version of the Neonatal Eating Assessment Tool (NeoEAT)-Bottle-feeding in postdischarge preterm infants in Türkiye.

Materials And Methods: A Turkish version of the NeoEAT-Bottle-feeding was developed and applied to 321 mothers of preterm infants younger than 7 months of corrected age between August 2021 and December 2022. Cronbach's alpha, exploratory factor, confirmatory factor, item-total correlation, test-retest, and known-groups validity analyses were performed.

Results: The Turkish NeoEAT-Bottle-feeding has 60 items in five factors explaining 55.785% of the total variance. Exploratory factor analysis indicated that the item factor loading ranged from 0.320 to 0.792. The known-group validity analysis confirmed that preterm infants with diagnosed feeding problems had higher total and subscale scores than those without (p = 0.001). The Cronbach's alpha (α) of the entire scale was 0.96. The item-total correlation coefficients were between 0.31 and 0.77 (p = 0.001). There was excellent agreement between test values and retest values obtained after a 2-week interval (intraclass correlation coefficient: 0.930-1.000).

Conclusion: The Turkish NeoEAT-Bottle-feeding was shown to be a reliable and valid parent-reported assessment tool for oral feeding skills and difficulties after neonatal intensive care unit discharge in bottle-fed preterm infants younger than 7 months of corrected age. Healthcare professionals can use this assessment tool during the initial evaluation of risk factors contributing to problematic feeding and to determine the effectiveness of planned interventions in preterm infants.
