尽管已经探讨了心理社会因素与身体活动的关系，但人们对社区环境的感知如何影响行为越来越感兴趣。然而，很少有方法论研究纳入对社会和社区环境（保护性社会因素）的看法或解决关键的衡量问题。对 1,818 名美国成年人进行了计算机辅助电话访谈。计算未调整和多变量调整的比值比，通过保护性社会因素 (PSF) 评分和选定的社会人口统计数据来比较活跃和不活跃的参与者。验证性因素分析和可靠性分析表明 PSF 量表具有很强的心理测量特性 (alpha =.92)。对潜在的混杂因素进行调整后，PSF 分数提高 10 分，满足疾病控制与预防中心/美国运动医学学院建议的可能性增加 12%。其他分析表明，在白人中，更大的感知 PSF 与满足这些建议有关，但在非裔美国人中则不然。
Although the relationship of psychosocial factors to physical activity has been explored, there is increased interest in how perceptions of the community environment influence behavior. However, few methodological studies have incorporated perceptions of the social and community environment (protective social factors) or addressed key measurement issues. Computer-assisted telephone interviews were administered to a national sample of 1,818 U.S. adults. Unadjusted and multivariate-adjusted odds ratios were calculated to compare active and inactive participants by Protective Social Factors (PSF) scores and selected sociodemographics. Confirmatory factor analysis and reliability analysis suggested strong PSF scale psychometric properties (alpha =.92). After adjustment for potential confounders, a 10-point rise in the PSF score resulted in a 12% increased likelihood of meeting Centers for Disease Control and Prevention/American College of Sports Medicine recommendations. Additional analyses indicated that greater perceived PSFs were associated with meeting these recommendations among Whites but not among African Americans.
