Our objective was to assess the concurrent validity of the face valid food security categorical algorithm with Hawaii residents. We also hypothesized that there would be differences in food security status between ethnic groups. We used the 18 question indicators of the Core Food Security Module (CFSM) to develop the face valid food security measure. The “face valid” measure was created previously by this research team as a more valid food security measure in Hawaii. Findings compared the face valid categorical measure and the CFSM scale measure with various demographic, economic, dietary variables, and use of assistance programs. The sample included 1,603 Hawaii residents drawn from a statewide telephone survey and a survey of charitable food recipients. Statistical analysis included ANOVA, chi-square, and regression analysis of food security measures with related variables. In general, progressively deteriorating food security status resulted in concurrent decreases in vegetable intake, increased reliance on a cheap, high-fat, high-sodium noodle product, and increased reliance on resource augmentation behaviors. Factors such as a greater number of children, limited savings, and recent loss of a job were found to compromise food security status. WIC benefits, frequent use of a food pantry, and the presence of a senior adult in the household appeared protective. In this sample Asians, except for Filipinos, were more food secure; Hawaiians and Part-Hawaiians, and Samoans, were more likely to experience hunger. Findings were consistent with previous work and suggest that the face valid food security measure does exhibit concurrent validity.
