O objetivo foi verificar a estrutura fatorial do questionário de adoção do óleo vegetal in natura de acréscimo na dieta infantil. Estudo transversal, com 220 mães de crianças, questionário em escala Likert. Treze juízes, especialistas em nutrição infantil, avaliaram semanticamente os itens e o Coeficiente de Generalização (CG) mensurou erros de avaliação, segundo modelo randômico de duas facetas (item/juiz), uma ocasião. A Análise Fatorial Exploratória (AFE) indicou dimensionalidade do instrumento aplicado: teste Doornik-Hansen, Análise de Fator Principal, critério Kaiser Guttman, rotação Promax, teste Kaiser-MeyerOlkin (KMO), validades convergente e discriminante, coeficiente alfa de Cronbach, Confiabilidade Composta. O CG=0,8407 foi considerado satisfatório. O teste Doornik-Hansen (chi 2 (28)=198,053, prob>chi 2 =0,0000) inferiu sobre a normalidade multivariada dos dados. O critério de Kaiser Guttman indicou 76,32% da latência do construto. A correlação entre os fatores 1 e 2 (-0,4042) sugere a bidimensionalidade do instrumento. KMO (0,8740) indicou a adequação dos dados para AFE. O alfa de Cronbach apresentou valores em torno de 0,70, considerados aceitáveis. Verificou-se bidimensionalidade do questionário para avaliar a adoção da prática do acréscimo de óleos vegetais in natura na dieta infantil.

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.
