Food security is a newly recommended outcome measure for the Older Americans Act Nutrition Program (OAANP); however, it is unknown how best to evaluate the need for this program and assess its impact on a large scale. Therefore, we measured food security in all new OAANP participants and waitlisted applicants in Georgia between July and early November, 2008 (n = 4731) with the self-administered mail survey method used in the ongoing Georgia Performance Outcomes Measures project. We used a modified 6-item U.S. Household Food Security Survey Module (HFSSM) with a 30-d reference period and 2 reminder postcards. Approximately 33% of those identified completed the survey (n = 1594, mean age 74.6 ± 9.5 y, 68.6% female, 30.6% black). Most of the respondents (91%) completed all 6 food security questions, whereas 26 did not respond to any question. Infit and outfit statistics for each of the 6 questions were within an acceptable range. Psychometric properties observed in our food security data were generally similar to those in the nationally representative survey conducted by the Census Bureau and suggest that our food security statistics may be meaningfully compared with national food security statistics published by the USDA. Our findings suggest that food security can be reasonably measured by a short form of HFSSM in older adults requesting OAANP. Such methodology also can be used to estimate the extent of food insecurity and help guide program and policy decisions to meet the nutrition assistance needs of vulnerable older adults.
