Questionnaire: Level of knowledge of the urban population about agroecological foods

Introduction. Food consumption affects the environment, so it is necessary to investigate what level of knowledge the urban population has about the origin of the food they consume. Objective. To design, validate, and determine the reliability of an instrument to assess the level of knowledge that t...

description Introduction. Food consumption affects the environment, so it is necessary to investigate what level of knowledge the urban population has about the origin of the food they consume. Objective. To design, validate, and determine the reliability of an instrument to assess the level of knowledge that the urban population has regarding agroecological foods. Materials and methods. The work was developed at the Universidad Central de Ecuador in Quito, Ecuador, during the period 2020-2021. The type of research was exploratory-descriptive, with a non-experimental design and stratified non-probabilistic sampling. The content of the instrument was evaluated using the Delphi method with the participation of seventeen experts. Two pilot tests were applied to 370 and 1323 participants. The internal consistency and the homogeneity index were determined using Cronbach’s Alpha. The dimensionality of the construct was established with the Cronbach-Mesbah curve. Construct validity was assessed with factor analysis. Results. The content validity showed a value greater than 75 % of convergence between experts. In the internal consistency validation, Cronbach’s Alpha was 0.9 and the homogeneity index was greater than 0.2. In the study of the dimensionality of the construct, the Cronbach-Mesbah curve indicated that the unidimensionality was fulfilled throughout the instrument. In the construct validity in the factor analysis, it was observed that the Kaiser-Meyer-Olkin measure was 0.753. Bartlett’s sphericity was 0.000 and the factor extraction test was greater than 77 %. Conclusions. The instrument achieved high validity and reliability both in its content assessed by experts, and in its internal consistency, dimensionality, and construct validity performed by statistical methods. The instrument is reliable and can be applied in the urban population.

El tipo de investigación fue exploratorio-descriptivo, con un diseño no experimental y un muestreo no probabilístico estratificado. El contenido del instrumento se evaluó con el método delphi con la participación de diecisiete expertos. Se aplicaron dos pruebas piloto a 370 y 1323 participantes. La consistencia interna y el índice de homogeneidad se determinó mediante el alpha de Cronbach. La dimensionalidad del constructo se estableció con la curva de Cronbach-Mesbah. La validez del constructo se evaluó con un análisis factorial. Resultados. La validez del contenido arrojó un valor mayor al 75 % de convergencia entre expertos. En la validación de la consistencia interna el Alpha de Cronbach fue de 0,9 y el índice de homogeneidad fue mayor de 0,2. En el estudio de la dimensionalidad del constructo la curva de Cronbach-Mesbah, indicó que la unidimensionalidad se cumplió en todo el instrumento. En la validez del constructo en el análisis factorial, se observó que la medida Kaiser-Meyer-Olkin fue de 0,753. La esfericidad de Bartlett fue de 0,000 y la prueba de extracción de los factores fue mayor al 77 %. Conclusiones. El instrumento logró una validez y confiabilidad alta tanto en su contenido valorado por expertos, como en su consistencia interna, dimensionalidad y validez del constructo realizado por métodos estadísticos. El instrumento es confiable y puede ser aplicado en la población urbana.Universidad de Costa Rica2022-11-16info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articletext/xmlapplication/pdfapplication/epub+ziptext/htmlaudio/mpegaudio/mpeghttps://revistas.ucr.ac.cr/index.php/agromeso/article/view/4835910.15517/am.v34i1.48359Agronomía Mesoamericana; 2023: Agronomía Mesoamericana: Vol. 34, Issue 1 (January-April) ; 48359 Agronomía Mesoamericana; 2023: Agronomía Mesoamericana: Vol. 34, Nº 1 (enero-abril) ; 48359Agronomía Mesoamericana; 2023: Agronomía Mesoamericana: Vol. 34, Nº 1 (enero-abril) ; 483592215-36081021-7444reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspaenghttps://revistas.ucr.ac.cr/index.php/agromeso/article/view/48359/53416https://revistas.ucr.ac.cr/index.php/agromeso/article/view/48359/53417https://revistas.ucr.ac.cr/index.php/agromeso/article/view/48359/53418https://revistas.ucr.ac.cr/index.php/agromeso/article/view/48359/53420https://revistas.ucr.ac.cr/index.php/agromeso/article/view/48359/53421https://revistas.ucr.ac.cr/index.php/agromeso/article/view/48359/53422Derechos de autor 2022 Ramiro José Vivas-Vivas, Jaime Alberto Pazmiño-Mayorga, Jorge David Caicedo-Chávez, Darío Alexander Cepeda-Bastidas, Ivanna Katherine Corro-Alarcónhttps://creativecommons.org/licenses/by-nc-nd/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2023-06-16T13:42:49Zoai:portal.ucr.ac.cr:article/48359Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:29:54.620Portal de Revistas UCR - Universidad de Costa Ricafalse
