中文摘要：

目的在杭州市6个社区中研究城市体力活动相关建成环境评价工具的信度和效度。方法在杭州市按公共建筑开发功能区选取6个社区共205个路段,2名调查员同时独立进行调查评价调查者间信度,间隔7 d重复调查约一半路段（104个）评价调查者内信度。采用因子分析方法检验结构效度。结果问卷调查者间信度Kappa值大部分在0.8以上;调查者内信度低于调查者间信度,Kappa值大部分在0.4以上。问卷表面效度良好。结构效度研究提取了6个因子,符合问卷的初始题目设计,因子负荷矩阵显示问卷结构效度良好。结论此建成环境评价量表的信度、效度较好,适合在杭州使用。

英文摘要：

Objective To study the reliability and validity of urban built environment evaluation tool for physical activity.Methods Six communities in Hangzhou City were selected according to urban public building functional area.A total of 205 segments were assessed.A pair of auditors assessed the street segments at the same time but worked independently.Approximately half of the segments（n=104） were audited twice by the same auditor 7 days apart.Inter-rater reliability was assessed by comparing the audits of pairs of auditors,while intra-rater reliability was evaluated by comparing an auditor’s repeated assessments of the same segments.The construct validity was tested by using factor analysis.Results The majority of inter-rater reliability was above 0.8.Intra-rater reliability was lower than inter-rater reliability.The majority of intra-rater reliability was above 0.4.The face validity of questionnaire was good.Six factors were found by factor analysis and the factor loading matrix showed that construct validity was good.Conclusions The evaluation tool is a reliable and validated measure of urban built environment in Hangzhou City.
