Approximately one in ten adults under the age of 65 in the USA has a mobility impairing disability. People with mobility impairment generally have poorer dietary habits contributing to obesity and related negative health outcomes. This article presents the psychometric properties of the Food Environment Assessment Survey Tool (FEAST) instrument that measures barriers to accessing healthy food from the perspective of people with mobility impairment (PMI).
The current study presents cross-sectional data from two sequential independent surveys.
Surveys were administered online to a national sample of PMI.
Participants represented PMI living throughout the USA. The pilot FEAST survey involved 681 participants and was used to shape the final instrument; 25 % completed a retest survey. After following empirically and theoretically guided item reduction strategies, the final FEAST instrument was administered to a separate sample of 304 PMI.
The final twenty-seven-item FEAST instrument includes items measuring Neighbourhood Environment, Home Environment, Personal Control and Access to Support (Having Help, Food Delivery Services, Parking/Transportation). The final four scales had acceptable intra-class correlations, indicating that the scales could be used as reliable measures of the hypothesised constructs in future studies.
The FEAST instrument is the first of its kind developed to assess the food environment from the perspective of PMI themselves. Future studies would benefit from using this measure in research and practice to help guide the development of policy aimed at improving access to healthy food and promoting healthy eating in community-dwelling PMI.
在美国，65 岁以下的成年人中，大约每 10 人就有 1 人存在行动障碍。行动障碍患者的饮食习惯通常较差，容易导致肥胖和相关的负面健康后果。本文介绍了食物环境评估调查工具（FEAST）的心理测量学特性，该工具从行动障碍患者（PMI）的角度衡量获取健康食物的障碍。
本研究呈现了两项独立的横断面调查的交叉数据。
通过在线向全国范围内的 PMI 样本发放调查问卷。
参与者代表居住在美国各地的 PMI。试点 FEAST 调查涉及 681 名参与者，用于塑造最终工具；25%的参与者完成了重测调查。在遵循经验和理论指导的项目删减策略后，最终的 FEAST 工具被用于 304 名独立的 PMI 样本。
最终的 27 项 FEAST 工具包括衡量邻里环境、家庭环境、个人控制和获得支持（帮助、食品配送服务、停车/交通）的项目。最终的四个量表具有可接受的组内相关系数，表明这些量表可以在未来的研究中作为假设构念的可靠测量工具。
FEAST 工具是同类工具中的首创，旨在从 PMI 自身的角度评估食物环境。未来的研究将受益于在研究和实践中使用该测量工具，以帮助指导旨在改善健康食物获取和促进社区居住的 PMI 健康饮食的政策的制定。
