Infant Positioning Assessment Tool: Transcultural adaptation and validation for Portuguese Preterm Neonates

Abstract

AimCross-cultural adaptation and validation of the Infant Positioning Assessment Tool for Portuguese Preterm Neonates. BackgroundTherapeutic positioning provides postural support, with immediate and long-lasting impacts on development. Some studies have suggested the importance of applying positioning-related instruments. MethodsA scoping review identified the Infant Positioning Assessment Tool, which was used in a methodological and cross-cultural study. Its psychometric validation was performed in a nonprobability preterm neonates sample (n = 90). Internal consistency and item sensitivity were assessed by using Cronbach's alpha coefficient and asymmetry and kurtosis coefficients, respectively. The following empirical indices were used to assess convergent validity (CV): chi-square over degrees of freedom (df), a goodness-of-fit index (GFI), a normed-fit index (NFI), an incremental-fit index (IFI) and root mean square error of approximation (RMSEA), an average extracted variance index, and composite reliability (CR). ResultsConfirmatory factor analysis of the factorial model showed an insufficient goodness-of-fit adjustment for the first model, with six items. One item was removed, and the resulting second model was adjusted to five items and showed more acceptable results (X2(9) = 52.70; p < 0.001; X2/df = 5.85; n = 90; GFI = 0.86; NFI = 0.64; IFI = 0,68; CFI = 0,67; RMSEA = 0.234); CR = 0.74 and CV = 0.50. ConclusionThe Portuguese version of the Infant Positioning Assessment Tool, with five items, proved to be a sensitive, valid, and reliable instrument for observing positioning of newborns, which is why its use in neonatal units is suggested.
