背景本文介绍了一个实用工具的发展，可靠性和收敛效度的便利店支持健康环境促进生命的食品（SHELF）审计。方法审核项目包括：各种新鲜、加工和冷冻水果和蔬菜;低脂乳制品;健康主食和冷冻餐;健康食品激励计划;在结账区出售的物品;份量/杯子大小;和定价。每个审计项目使用五点语义差异量表进行评分（1 =对健康食品提供很少或没有支持，5 =对健康食品提供高度支持）。通过比较SHELF审计与Ghirardelli等人和Laska等人的商店审计来检查收敛有效性。统计分析包括：因子分析，方差分析，和斯皮尔曼相关。结果SHELF包括三个因素：水果/蔬菜量表（8个项目，= 0.79，总潜能点= 34）;健康食品量表（4个项目，= 0.72，总潜能点= 16）;支持量表（4个项目，= 0.685，总潜能点= 16）。在124家被评估的便利店中，只有6%的商店得分在最健康的范围内（46 - 66）。评估的药店（n = 15）得分高于便利店（n = 81）的健康食品和支持规模，但不是水果/蔬菜规模。SHELF分项得分与其他审计工具高度相关，表明收敛效度。结论SHELF便利店审计是一个有效的，可靠的工具，评估便利店支持健康的程度，水果/蔬菜，健康食品，并支持选择健康。
Background This paper describes the development, reliability, and convergent validity of a practical toolthe Convenience Store Supportive Healthy Environment for Life-Promoting Food (SHELF) Audit. Methods Audit items included: a variety of fresh, processed, and frozen fruits and vegetables; low-fat dairy products; healthy staples and frozen meals; healthy food incentive programs; items sold in check-out areas; portion/cup sizes; and pricing. Each audit item was scored using a five-point semantic-differential scale (1 = provides little or no support for healthful foods to 5 = provides high support for healthful foods). Convergent validity was examined by comparing the SHELF audit to Ghirardelli et al. and Laska et al. store audits. Statistical analysis included: Factor analysis, ANOVA, and Spearman correlations. Results SHELF included three factors: a Fruits/Vegetables scale (eight items, = 0.79; total potential points = 34); a Healthy Foods scale (four items, = 0.72; total potential points = 16); and a Supports scale (four items, = 0.685; total potential points = 16). Only 6% of the 124 convenience stores assessed scored in the most healthful range (46-66). The assessed drug stores (n = 15) scored higher than convenience stores (n = 81) on the Healthy Foods and Supports scales but not the Fruits/Vegetables scale. The SHELF sub-scores were highly correlated with other audit tools indicating convergent validity. Conclusion The SHELF convenience store audit is a valid, reliable tool for assessing the degree to which convenience stores support healthfulness regarding Fruits/Vegetables, Healthy Foods, and Supports for choosing healthy.
