Resumen

FLORES-VILLALBA, David; AYALA-GAYTAN, Edgardo Arturo  y  QUINTANILLA-DOMINGUEZ, Claudia María. Development of a scale of use, comprehension and attitudes in relation to nutrition labels in Spanish. Salud pública Méx [online]. 2019, vol.61, n.1, pp.63-71.  Epub 01-Ene-2019. ISSN 0036-3634.  https://doi.org/10.21149/8606.

Objective:

To describe the development of a reliable and valid measure of attitudes toward, and use and comprehension of nutritional labels in Spanish speaking countries.

Materials and methods:

The dimensions encompassed in this instrument are attitudes, comprehension and use, combining self-reports and objective measures of nutrition knowledge. Content validity, item analysis, repeat and internal reliability, and convergent and divergent validity were assessed in a pooled sample of 185 individuals.

Results:

Cronbach alpha coefficients (above 0.9) exhibit internal consistency. Exploratory and confirmatory factor analyses of the scale show good properties for convergent and divergent validity.

Conclusion:

The final 25-item scale is a valid and reliable measure of use, comprehension and attitude towards nutrition labels for Spanish speaking populations.

Palabras llave : nutrition labeling; scale/development; validity and reliability.
