目标.本研究调查了通过自我报告和客观审计获得的身体活动设施的措施之间的对应关系;并确定了社会人口统计学，认知和行为特征的那些谁认为他们的身体活动的环境是支持比客观措施indicate. Methods。自我报告的调查完成了1540名妇女从45个社区在墨尔本，澳大利亚招募。妇女报告说，在离家2公里的范围内，她们认为可以使用体育活动设施，同时也考虑到社会人口、认知和行为因素。客观的数据，在一个2公里的步行集水区周围的妇女的家的身体活动设施的来源。通过自我报告和客观评估获得的获得体育活动设施的措施之间的协议相对较差。感知和客观评估的环境之间的不匹配是更常见的年轻和老年妇女，低收入的妇女，低自我效能的身体活动，谁是不太活跃，谁报告使用较少的设施，谁住在附近不到2年。未来的身体活动的环境决定因素的研究应考虑纳入客观指标的设施，或占系统的偏见，可能会导致依赖自我报告的看法作为实际的身体活动环境的指标。(C)2008年爱思唯尔公司All rights reserved.
Objectives. This study investigated the correspondence between measures of physical activity facilities obtained through self-report and objective audits; and identified the socio-demographic, cognitive and behavioral characteristics of those who perceive their physical activity environment to be less supportive than objective measures indicate.Methods. Self-report surveys were completed by 1540 women recruited from 45 neighborhoods in Melbourne, Australia. Women reported perceived access to physical activity facilities within 2 km from home, and also socio-demographic, cognitive and behavioral factors. Objective data on physical activity facilities within a 2 kin pedestrian catchment area around women's homes were sourced.Results. There was relatively poor agreement between measures of access to physical activity facilities obtained via self-report and objective assessment. Mismatch between perceived and objectively-assessed environments was more common amongst younger and older women, and women of low income, with low self-efficacy for physical activity, who were less active, who reported using fewer facilities and who had lived in the neighborhood for less than 2 years.Conclusions. Future studies of environmental determinants of physical activity should consider incorporating objective indices of access to facilities, or accounting for the systematic bias that may result from relying on self-report perceptions as an indicator of the actual physical activity environment.
