Abstract:

The aim was to investigate the factor structure of the questionnaire adoption of the vegetable oil in natura increase in children‘s diet: cross-sectional study, 220 mothers of children, questionnaire Likert Scale. Thirteen judges, experts on Child Nutrition, semantically evaluated the items; the Generalizability Coefficient (GC) valued the errors, according to a two-facet random model (item/judge), one occasion. The Exploratory Factor Analysis (EFA) indicated dimensionality of the instrument applied: Doornik-Hansen Test, Main Factor Analysis, Kaiser Guttman criterion, Promax rotation, Kaiser-Meyer- Olkin test (KMO), convergent and discriminant validities, Cronbach’s alpha and Composite Reliability. The GC=0.8407 was considered satisfactory. The Doornik-Hansen (chi2 (28)=198.053, prob>chi2 =0.0000) allowed to infer the multivariate normality of data. The Kaiser Guttman criterion explained 76.32% of the latent construct. The correlation between factors 1 and 2 (-0.4042) suggests the two dimensional nature of the instrument. The KMO (0.8440) indicated the adequacy of the data to perform EFA. Cronbach’s alpha showed values around 0.70, considered acceptable. The two-dimensionality of the questionnaire was verified to assess the adoption of the practice of adding in natural vegetable oils to children’s diet.
