社区属性测量量表的修订及其信效度评价

目的修订社区属性测量量表(MPNS)并对其进行信效度评价。方法采用分层随机抽样对上海市7729名18~75岁的社区常住居民进行问卷调查;调查内容包括性别、年龄、文化程度、城郊区以及自评健康;社区属性使用汉化版社区属性测量量表进行评估,该量表包括美化质量、步行环境、社会凝聚力、社会参与,共24个条目4个维度。采用探索性因子分析对原量表进行修订,并在不同地区和不同年龄段的社区成年居民中对修订版量表进行信度和效度分析。结果量表由24个条目4个维度修订为27个条目6个维度,包括街边环境、美化质量、步行环境、社会凝聚力、社会参与和社会联系,解释总变异68.9%。修订版量表的Cronbach’sα系数为0.89,各分量表的Cronbach’s α系数为0.51~0.92;总量表分半信度为0.91。修订版量表具有良好的区分效度和结构效度,并且验证性因子分析模型各项参数均可接受。结论修订版社区属性测量量表具有较好的信度和效度,并且基本适用于所有社区≤75岁的成年居民。

Revision and validation of measurement properties of neighborhood scales

OBJECTIVE To revise the Measurement Properties of Neighborhood Scales(MPNS), and to evaluate their reliability and validity. METHODS Seven thousand seven hundred and twenty-nine community-based residents aged 18-75 years were selected by stratified random sampling, and gender, age, educational level, urban-suburban area and self-rated health were documented. The community attributes were assessed with the Chinese version of MPNS, which consists of 24 items, and 4 dimension including aesthetic quality, walking environment, social cohesion, and social participation. The scale were revised using exploratory factor analysis, and the reliability and validity of the revised scale were tested among community-based adults in different areas and different ages. RESULTS The scale was revised from 24 items, 4 dimension to 27 items, 6 dimension, which included street environment, aesthetic quality, walking environment, social cohesion, social participation and social connection, and could explain 68.9% of the total variance. The Cronbach’s α of revised scale was 0.89 and the Cronbach’s α of each subscales were range from 0.51 to 0.92, the split-half reliability was 0.91. The revised scale had favorable discriminant validity and construct validity. In addition, various parameters of the confirmatory factor analysis were all acceptable. CONCLUSION Revised Chinese version of MPNS is reliable and valid among community-based adults≤75 years.
