Psychometric Properties of the Self-efficacy Scale for a Healthy Diet in Individuals with Obesity
##plugins.themes.bootstrap3.article.main##
Resumen
Objetivo. Desarrollar un instrumento que mida la autoeficacia para una alimentación saludable en población mexicana con obesidad. Con ello se obtuvieron las propiedades psicométricas de la Escala de Autoeficacia para una Alimentación Saludable (EAAS).
Método. La muestra incluyó 202 personas adultas con obesidad que se encontraban en tratamiento para reducir su peso corporal. Se aplicó la EAAS; ésta es una Escala tipo Likert desarrollada con base en el Modelo Procesual de Acciones en Salud (HAPA, por sus siglas en inglés) y consta de 45 reactivos. Se obtuvo la validez de constructo, se estimaron coeficiente omega y análisis factorial confirmatorio para obtener las propiedades psicométricas.
Resultados. La escala tiene buenas medidas de bondad de ajuste χ2 = 66.49; p < .001; χ2 S-B/gl = 41; CFIS = .955; NFI = .893; RMSEAS = .056 (IC 95% [.029, .079]) y de confiabilidad de la escala total ω = .896 (IC 95% [.876, .915]).
Discusión y conclusión. La EAAS es un instrumento válido y confiable para medir los tres tipos de autoeficacia que propone el modelo HAPA en personas con obesidad que requieren cambios en la conducta alimentaria.
