Title A name given to the resource Validación de escala de la seguridad alimentaria doméstica en Antioquia, Colombia Validation of a household food security scale in Antioquia, Colombia Creator An entity primarily responsible for making the resource Hugo Melgar-Quiñonez, Marta Cecilia Álvarez, Alejandro Estrada, Elizabeth Cristina Montoya Description An account of the resource OBJETIVO: Adaptar y validar en hogares de Antioquia, Colombia, una escala de seguridad alimentaria anteriormente aplicada en hogares de Caracas, Venezuela. MATERIAL Y MÉTODOS: El estudio se realizó en 44 municipios del departamento de Antioquia, Colombia, durante los años 2003 y 2004, en una muestra representativa de los hogares rurales y urbanos del departamento de Antioquia, constituida por 1 624 hogares con niños menores de 10 años; los hogares fueron seleccionados de manera aleatoria, con un índice de confianza de 95% y un error de 3%. Se validó la escala de seguridad alimentaria doméstica utilizada por Paulina Lorenzana en Venezuela, y se determinó la consistencia interna de la escala mediante el coeficiente de correlación de Spearman y el coeficiente alfa de Cronbach. La validez del constructo se estableció mediante el método de componentes principales para datos categóricos. Se utilizaron el procedimiento de Prinqual y el modelo de Rasch para definir los componentes y los ��tems de la escala. RESULTADOS: El análisis factorial arrojó dos componentes: 1) las variables relacionadas con 'inseguridad alimentaria sin hambre' que lo explican en 95% y 2) las relacionadas con 'inseguridad alimentaria con hambre' que lo explican en 89.4%. El coeficiente alfa de Cronbach para el primer componente fue de de 0.95 y para el segundo de 0.89. Al ser analizados con el modelo Rasch, todos los ítems presentaron valores infit en un rango de 0.8 a 1.2. La escala se correlacionó significativamente con la disponibilidad de alimentos, el recurso de la limosna, el trabajo infantil, el tamaño del hogar y la ocupación del jefe de familia (p< 0.000). CONCLUSIÓN: La escala puede considerarse un instrumento confiable para la valoración de la inseguridad alimentaria en los hogares de Antioquia.OBJETIVE: To adapt and validate in households of Antioquia, Colombia, a food security scale previously applied in households of Caracas, Venezuela. MATERIAL AND METHODS: The study was carried out in 44 municipalities in the department of Antioquia, Colombia, in 2003 and 2004, with a randomly selected sample of 1 624 rural and urban households with children under 10 years of age, representative for family units located in the department of Antioquia. The sample was selected using a confidence interval of 95% and an error of 3%. Household food security scale previously used by Paulina Lorenzana in Venezuela were validated for this survey. Internal consistency of the scale was determined using the Spearman correlation coefficient and Cronbach's Alpha coefficient. Construct validity was established through principal components analysis for categorical data. Prinqual procedure and Rasch modeling were used to define the components and items in the scale. RESULTS: Factor analysis showed two components: 1) variables related to 'food insecurity without hunger', which is explained in 95%; 2) variables related to 'food insecurity with hunger', which is explained in 89.4%. Cronbach's Alpha coefficients for 'food insecurity without hunger' and 'food insecurity with hunger' were 0.95 and 0.89, respectively. When analyzed using Rasch modeling, all items showed infit values within a range of 0.8 and 1.2.
