Abstract

The present study focuses on the validation of instruments that allow to measure the practices and perceptions of sustainable feeding prior validation of the translation, due to the obtaining of the questionnaires in a foreign language. The compilation form was administered to 161 students between 10 and 15 years of the public education unit "Herlinda Toral" located in the urban sector of the city of Cuenca. This study is part of the final validation of the questionnaires, and aims at the global validation of the instruments, which is a preliminary analysis of the correlation and interpretation of the estimates of the internal consistency and reliability of the measurements test and re-test, in order to open the way to a more in-depth study such as structural validation through exploratory and confirmatory factor analysis. The results for the validation of the internal consistency through the Cronbach's alpha coefficient reveal a satisfactory interpretation (α=0.61-0.91) for all the questionnaires; except for attitude and use of animals, means of information on the consumption of insects and consumption of insects (α=0.14-0.47), and of those with only one item. These satisfactory values were confirmed by the acceptable values of the omega coefficient (ω=0.69-0.91), which excludes the limitations of Cronbach's alpha. In the same way, a moderate, good and excellent reliability of the test and re-test measurements was determined, by calculating the values of the intraclass correlation coefficient between 0.54 and 0.92.
