Introduction : Measuring hunger and food insecurity has always been a challenge given the various tools available to provide estimates both at the macro (sufficiency in staple stock) and micro (household food security) levels. In the Philippines estimates of food insecurity have been provided by the Food and Nutrition Research Institute (FNRI) starting 2001 using an adaptation of the Radimer/Cornell (1992) measures of hunger and food insecurity. The tool has been found to be reliable using the 2003 data extracted from the sixth National Nutrition Survey (NNS) Food Security module but was recommended for further exploratory factor analysis to test for efficiency of items. Methods : This study assessed the construct validity of the adapted Radimer/Cornell instrument for measuring household food insecurity using principal component analysis with varimax rotation based on the 2003 NNS data. Results : The results revealed the prevalence of food insecurity was higher at the mothers level (33.7) compared to the child (21.0) indicative of managed process� or coping with food insecurity at the households. Altered eating� emerged (factor 1) at the individual level of food insecurity while anxiety over quantity and quality of food� was (factor 2) at the household level that explained 44.0 and 23.2 of the total variance respectively. Thus a high cumulative variance (67.2) was generated for these two factors implying sufficient variance was obtained to justify the derivation of these two factors from the dataset. Conclusion : The food security items in the adapted Radimer/Cornell instrument contained valid indicators for assessing food insecurity in Filipino households.

Abstract

Introduction : Measuring hunger and food insecurity has always been a challenge given the various tools available to provide estimates both at the macro (sufficiency in staple stock) and micro (household food security) levels. In the Philippines estimates of food insecurity have been provided by the Food and Nutrition Research Institute (FNRI) starting 2001 using an adaptation of the Radimer/Cornell (1992) measures of hunger and food insecurity. The tool has been found to be reliable using the 2003 data extracted from the sixth National Nutrition Survey (NNS) Food Security module but was recommended for further exploratory factor analysis to test for efficiency of items. Methods : This study assessed the construct validity of the adapted Radimer/Cornell instrument for measuring household food insecurity using principal component analysis with varimax rotation based on the 2003 NNS data. Results : The results revealed the prevalence of food insecurity was higher at the mothers level (33.7) compared to the child (21.0) indicative of managed process� or coping with food insecurity at the households. Altered eating� emerged (factor 1) at the individual level of food insecurity while anxiety over quantity and quality of food� was (factor 2) at the household level that explained 44.0 and 23.2 of the total variance respectively. Thus a high cumulative variance (67.2) was generated for these two factors implying sufficient variance was obtained to justify the derivation of these two factors from the dataset. Conclusion : The food security items in the adapted Radimer/Cornell instrument contained valid indicators for assessing food insecurity in Filipino households.
