Abstract:

The objective was to develop an instrument to evaluate the knowledge which adult women have of food combinations in order to make iron bioavailable in the children`s diet. We conducted an exploratory factor analysis study (Likert scale) on a questionnaire in a sample comprising 151 women and used the Principal Factor Analysis and an estimator of likelihood ratio. We applied the Kaiser-Meyer-Olkin (KMO) test, the Doornik-Hansen test, the Kaiser Guttman criterion, the correlation between factors and theoretical assumptions. Reliability was assessed by Cronbach’s alpha and composite reliability. Total KMO (0.5942) showed adequacy of the sample. The Doornik-Hansen test showed multivariate normality of the scores observed. Factorial loads, error variance of items and correlation between factors pointed to the two-dimensional nature of the questionnaire, which decreased from 30 to 15 items. Total Cronbach’s alpha was 0.8018 (95% CI = 0.7429 to 0.8606) and composite reliability (Factor 1 = 0.3125 and Factor 2 = 0.3263). Convergent and discriminant factorial validity and were acceptable. We concluded in favor of a reduction in the instrument (from 30 to 15 items) with reliability and validity that enable it for a further procedure of a confirmatory factor analysis.
