Abstract: This study aimed to investigate the effects of factor rotation methods on interpretability and construct validity of dietary patterns derived in a representative sample of 1,102 Brazilian adults. Dietary patterns were derived from exploratory factor analysis. Orthogonal (varimax) and oblique rotations (promax, direct oblimin) were applied. Confirmatory factor analysis assessed construct validity of the dietary patterns derived according to two factor loading cut-offs (≥ |0.20| and ≥ |0.25|). Goodness-of-fit in… Show more

“…Systematic reviews on the subject have criticized studies for the large numbers of steps that depend on researchers' choices and for a failure to state explicitly the criteria used at those stages 5,50 . On the other hand, little has been done in Brazil to problematize the choice of multivariate analysis as a method for defining dietary patterns, the exception being Castro et al 51 . The techniques most often used (factorial analysis and principal component analysis) presuppose the use of continuous variables.…”

“…We illustrated the application of PCA and FA in the nutrition field by using both multivariate methods on a matrix of 34 variables expressing the mean food intake (in grams/ day) of 1,102 individuals (aged 20 years and older) who responded to two non-consecutive 24-hour dietary recalls (24HDR) in a population-based study 11 . The study had two different objectives: to describe only the multidimensional data in PCA and the derivation of dietary patterns in FA.…”

“…Cattell, 1966;Preacher, Zhang, Kim, & Mels, 2013). Our results gave us a strong evidence pointing to a two factors solution (Castro et al, 2015). The labels were created based on the ASQ:SE background and the items content.…”

“…The extraction method was based on principal components and the rotation technique was Varimax. The varimax is a type of orthogonal rotation that attempts to maximize the variance of squared loadings on a factor to reduce the cross-loadings of the variables, leading to uncorrelated simple factor structures (Castro, Baltar, Selem, Marchioni, & Fisberg, 2015) and it was chosen because this is the most frequent rotation method applied in empirical research.…”
