班级地图量表中文版在初中生中的信效度检验

Reliability and Validity of Class Maps Survey in Chinese Middle School Students

目的:对班级地图量表(Class Maps Survey,CMS)的中文版进行修订并检验其在我国初中生群体中的信度和效度。方法:选取初中生603人(样本1)完成CMS,用于项目分析和探索性因子分析;另选取697名初中生(样本2)用于验证性因子分析、区分效度、内部一致性及分半信度检验,受测者同时完成CMS、学习压力问卷和核心自我评价量表。结果:CMS中文版包括师生关系、家校关系、同伴友谊、同伴冲突、同伴侵犯、学业自我效能感、学习自我决定、班级行为自控等八个因子,共50个项目;八因素模型拟合度良好(χ2/df=2.01,CFI=0.94,TLI=0.93,RMSEA=0.04,SRMR=0.04);CMS中文版具有较好的效标关联效度;总问卷的内部一致性系数为0.92,8个因子的内部一致性系数在0.71-0.92之间;总问卷的分半信度系数为0.70,8个因子的分半信度系数在0.72-0.87之间;重点初中的班级环境显著好于普通初中,而普通初中又显著好于打工子弟初中。结论:修订后的CMS中文版具有良好的效度和信度,适用于测量中国的班级环境对初中生的支持作用。

Objective： To revise Class-Maps Survey and investigate its reliability and validity in Chinese middle school students. Methods： 603 middle school students（samplel） completed the Chinese Version of CMS for item and exploratory factor analysis. 697 students（sample2） completed Academic Stress Questionnaire and Core Self-Evaluation Scale together with the CMS for confirmatory factor analysis, discriminant validity, internal consistency reliability and split-half reliability. Results： Chinese version of CMS was composed of 50 items, respectively related to 8 factors. The confirmatory factor analysis indicated good fit of the 8-factor model（χ^2/d[=2.01, CFI=0.94, TLI=0.93, RMSEA=0.04, SRMR=O.04）. The criterion-related validity of CMS was very good. Cronbach ＇ sot coefficient and Split-half reliability of the CMS was 0.92 and 0.70, respectively; Cronbach＇ sct coefficient of eight subscales ranged 0.71-0.92; Split-half reliability of eight subscales ranged 0.72-0.87; Key school was significantly better than regular school and the latter was better than migrant school on classroom environments. Conclusion： The revised Chinese version of CMS has good reliability and validity and can be used to assess the supportiveness of classroom environments to Chinese middle school students.
