DIAZ-RESENDIZ, Felipe de Jesús et al. Rating and frequency of healthy and non-healthy food consumption: a preliminary study. Rev. Mex. de trastor. aliment [online]. 2010, vol.1, n.2, pp.125-131. ISSN 2007-1523.

Nowadays there is not any instrument to measure reliably how healthy and non-healthy food is judged in Mexico. In this study it was used the first version of the scale Consumption and Estimation of Food (ECA for its Spanish acronym) designed to explore the rating and frequency of healthy and non-healthy food consumption. In the present study participated students from two public schools of Mexico State who judged 143 items rated on a Likert-type scale with five options each one. Reliability index for each section of the scale showed adequate statistical properties. Correlations total-item were analyzed and 75 items with correlations were considered to asses again the internal consistency of the scale. This analysis confirmed the internal consistency of the scale. Mean score for estimation was higher in men than female and mean for frequency of consumption was higher in female than male. For women the correlation between estimation and frequency was positive and significant. All the findings are comparable with previous research and suggest that it is necessary to improve the current version of the scale. The new version should be applied to new and wide samples.

Palabras llave : judgment; frequency; food; correlation; reliability.
