尽管文献记载了体育锻炼的好处，但许多成年人并没有达到建议的运动量。身体活动的障碍存在于多个层面，包括个人、人际和环境层面。直到最近，人们才一致关注物理环境如何影响身体活动行为。有了这个新的研究领域，自我报告的测量方法应该在用于研究之前进行心理测量学测试。因此，本研究的目的是记录一份问卷的重测信度，该问卷旨在评估不同成人人群中可能与体育活动相关的物理环境因素。研究人员通过电话对居住在北卡罗来纳州福赛斯县或密西西比州杰克逊的106名非裔美国人和白人男女进行了反复测试调查。在四个领域（例如，设施和目的地的访问、功能和安全、美学、自然环境）中，自我报告的环境因素的可靠性使用类内相关系数（ICC）来确定，并根据性别和种族分别确定。一般来说，项目显示出适度的可靠性，有时是实质性的可靠性（ICC在0.4到0.8之间），在每个领域中有一些性别或种族的差异。这项研究为在非裔美国人和白人女性和男性中研究自我报告的身体环境措施对体育活动行为的影响的研究中使用许多这些问题提供了一些心理测量学证据。
Despite the documented benefits of physical activity, many adults do not obtain the recommended amounts. Barriers to physical activity occur at multiple levels, including at the individual, interpersonal, and environmental levels. Only until more recently has there been a concerted focus on how the physical environment might affect physical activity behavior. With this new area of study, self-report measures should be psychometrically tested before use in research studies. Therefore the objective of this study was to document the test-retest reliability of a questionnaire designed to assess physical environmental factors that might be associated with physical activity in a diverse adult population. Test and retest surveys were conducted over the telephone with 106 African American and White women and men living in either Forsyth County, North Carolina or Jackson, Mississippi. Reliability of self-reported environmental factors across four domains (e.g., access to facilities and destinations, functionality and safety, aesthetics, natural environment) was determined using intraclass correlation coefficients (ICC) overall and separately by gender and race. Generally items displayed moderate and sometimes substantial reliability (ICC between 0.4 to 0.8), with a few differences by gender or race, across each of the domains. This study provides some psychometric evidence for the use of many of these questions in studies examining the effect of self-reported physical environmental measures on physical activity behaviors, among African American and White women and men.
