This study was designed to develop an abbreviated method that captures both the qualitative and quantitative dimensions of household food security (HFS).
Women in poor and very poor households (n=238) in a peri-urban barrio in Caracas, Venezuela, provided data on food availability and their perception of food resource constraints and hunger experiences within the home.
Socioeconomic data and food-related behavior that may predict HFS levels were gathered.
On average, the top 12 food contributors of energy provided 81% and predicted more than 90% of the variation in households'total energy availability using stepwise regression analysis.
On the other hand, a 4-point 12-item scale was shown to have face, content and construct validity with reiterative testing, factor analysis and a Chronbach's alpha coefficient of 0.92.
Assessing predictors of energy availability together with a self-perceived HFS scale may provide a valid and reliable method for identifying and monitoring food security levels among poor urban households.
