Aim: This study aimed to assess the validity and reliability of the Turkish version of the Household Food Security Survey Module-Short Form Scale with cultural adaptation and to compare the size of the problem of food accessibility of seasonal farmworkers with locals. Material and Method: This study is a methodological research executed in the 2012 agricultural season. The study group was composed of seasonal farmworkers in Eskisehir and residents located in rural areas next to the camp sites of seasonal farmworkers. The first part of the survey included socio-demographic characteristics of the household and the second part contained the Short Form of Household Food Security Survey Module. Exploratory factor analysis was conducted for construct validity and for internal criterion validity scores of seasonal farmworkers and locals. For reliability analysis, item total correlation and Cronbach alpha coefficients were measured. Results: Results of exploratory factor analysis indicated that the items are collected under one factor and explain 68.38% of the variance. Factor loadings of the items varied between 0.82 and 0.90. The difference between the upper and lower groups was significant (p <0.001), and the score of seasonal farmworkers was higher than that of the local population (p <0.001). The internal consistency coefficient was 0.904. It was found that 90.4% of the households of seasonal farmworkers were at risk of accessing food, while 36.6% of the local residents were at risk of accessing food (p <0.001). Discussion: The Turkish version of the Household Food Security Survey Module-Short Form is a valid and reliable measure evaluating nutritional access that can be applied in Turkish society. Food accessibility of seasonal farmworkers is a critical problem.
