Many individuals, particularly those of low socioeconomic status, do not have easy access to larger grocery stores and supermarkets, and often shop for food at nearby small/corner stores. A high density of small/corner stores is associated with mortality, diabetes, and obesity. This is likely due to the high concentration of processed, energy-dense, nutrient poor foods carried by these stores, combined with a lack of fresh produce, whole grains, and low-fat dairy products. However, when small neighborhood food stores devote more shelf space to fruits and vegetables, nearby residents consume more produce. Interventions that target small/corner food stores for increasing the availability and sale of healthy foods are being launched in many communities. Reliable tools must be used to evaluate the healthfulness of these stores, and a number of validated survey instruments have been developed for this purpose. However, these in-store surveys take approximately thirty minutes to conduct and require individual visits from investigators. These tools are appropriate for assessing the food environment in a single neighborhood or community, but many projects and studies assess the food environment in a large number of stores spread across broad geographical areas. In such cases, a thirty-minute in-person evaluation of each store is not feasible and is resource-prohibitive. Most large-scale studies tend to rely on commercial data sources that are known to have misclassification biases. Therefore, a more refined but feasible measure is needed. The aim of this study is to develop a valid and feasible short telephone survey that captures the healthfulness of small/corner stores.
