目的：本研究的目的是检验邻里环境步行性量表(NEWS)的因素效度和效标效度，并编制简明版本(NEWS-A)。方法：采用分层两阶段整群抽样设计，共招募1286名成人。该样本来自与社会经济地位相匹配的八个高步行社区和八个低步行社区的住宅区。受试者完成了新闻，并使用国际体力活动问卷中的项目报告了每周步行几分钟用于交通和娱乐。结果：采用多水平验证性因素分析建立了NEWS和NEWS-A的测量模型。确定了6个个体水平的因素和5个区块水平的因素。衡量目的地多样性、居住密度、步行基础设施、美学、交通安全和犯罪的因素/量表与步行代步交通呈正相关。美学、混合目的地和居住密度与步行娱乐有关。结论：新闻和新闻-A具有较高的因素效度和效标效度。对于不同的目的，提出了不同的评分方法。
Purpose: The aim of this study was to examine the factorial and criterion validity of the Neighborhood Environment Walkability Scale (NEWS) and to develop an abbreviated version (NEWS-A). Methods: A stratified two-stage cluster sample design was used to recruit 1286 adults. The sample was drawn from residential addresses within eight high- and eight low-walkable neighborhoods matched for socioeconomic status. Subjects completed the NEWS and reported weekly minutes of walking for transport and recreation using items from the International Physical Activity Questionnaire. Results: Multilevel confirmatory factor analysis was used to develop measurement models of the NEWS and NEWS-A. Six individual-level and five blockgroup-level factors were identified. Factors/scales gauging presence of diversity of destinations, residential density, walking infrastructure, aesthetics, traffic safety, and crime were positively related to walking for transport. Aesthetics, mixed destinations, and residential density were associated with walking for recreation. Conclusions: The NEWS and NEWS-A possess adequate levels of factorial and criterion validity. Alternative methods of scoring for different purposes are presented.
