前言：营养环境的客观观测方法现已确立并得到广泛应用。个人对其营养环境的看法可能同样重要或更重要，但概念化程度较低，也没有全面的衡量标准。方法：本研究包括五个步骤：(1)建立概念模型和条目清单；(2)专家评审；(3)试点测试和认知访谈；(4)修订问卷；(5)对高和低社会保障水平社区的参与者进行两次修订，以评估社区差异和重测信度。收集2010年和2011年的数据，并对2011年和2012年的数据进行分析。结果：最终调查有118个项目。53个核心条目代表三种类型的感知营养环境：社区营养环境、消费者营养环境和家庭食品环境。对于大多数测量的结构，感知营养环境的核心结构的重测信度为中到好(0.52-0.83)。结论：NEMS-P具有中等到良好的重测信度，能够区分高SES和低SES社区居民对营养环境的感知。此调查已准备就绪，可供使用。(C)《2015美国预防医学杂志》
Introduction: Objective, observational measures of nutrition environments are now well established and widely used. Individuals' perceptions of their nutrition environments may be equally or more important, but are less well conceptualized, and comprehensive measures are not available. This paper describes the development of the Perceived Nutrition Environment Measures Survey (NEMS-P), its test-retest reliability, and its ability to discern differences between lower- and higher-SES neighborhoods.Methods: This research involved five steps: (1) development of a conceptual model and inventory of items; (2) expert review; (3) pilot testing and cognitive interviews; (4) revising the survey; and (5) administering the revised survey to participants in neighborhoods of high and low SES on two occasions to evaluate neighborhood differences and test-retest reliability. Data were collected in 2010 and 2011 and analyzed in 2011 and 2012.Results: The final survey has 118 items. Fifty-three core items represent three types of perceived nutrition environments: community nutrition environment, consumer nutrition environment, and home food environment. Test-retest reliability for core constructs of perceived nutrition environments was moderate to good (0.52-0.83) for most measured constructs. Residents of higher-SES neighborhoods reported higher availability scores in stores, stronger agreement that healthy options were available in nearby restaurants, and higher scores for accessibility of healthy foods in their homes.Conclusions: The NEMS-P has moderate to good test-retest reliability and can discriminate perceptions of nutrition environments between residents of higher-and lower-SES neighborhoods. This survey is available and ready to be used. (C) 2015 American Journal of Preventive Medicine
