中文版锻炼认同量表测评大学生样本的信度与效度

Test of Chinese Exercise Identity Scale in College Students

目的:探讨锻炼认同量表(exercise identity scale,EIS)在大学生群体中应用的信度与效度,为研究大学生锻炼认同提供可靠测量工具。方法:在湖南省2所高校选取在校大学生为受试群体425名,通过重测信度、内部一致性信度、探索性因子分析、验证性因素分析等方法对量表的信度与效度进行检验。结果:探索性因子分析显示EIS为单因子结构,各条目的因子载荷均在0.50以上。验证性因子分析显示各项指标均拟合较好(χ~2/df=2.197、GFI=0.909、RMSEA=0.075、AGFI=0.906、CFI=0.943、IFI=0.968、PNFI=0.707、PGFI=0.566),量表的Cronbachα系数为0.90,重测信度为0.79。结论:锻炼认同量表中文版有较好的信度和效度,可以用作我国大学生锻炼认同的可靠测量工具。

Objective: To examine the validity and reliability of the Chinese Version of the Exercise Identity Scale(EIS)among the college students and provide a reliable measurement tool. Methods: 425 college students form two universities in Hunan Province were selected as the subjects. The reliability and validity of the scale were tested by retest reliability, internal consistency reliability, exploratory factor analysis and confirmatory factor analysis. Results: The exploratory factor analysis showed that EIS was a single factor structure, and the load of each item was more than 0.50. The confirmatory factor analysis showed that all the indexes were well fitted(χ2/df=2.197, GFI=0.909, RMSEA=0.075, AGFI=0.906, CFI=0.943,IFI=0.968, PNFI=0.707, PGFI=0.566). The Cronbach a of the scale was 0.90 and the retest reliability was 0.79. Conclusion: The Chinese version of the EIS has good reliability and validity, and it can be used as a reliable measurement tool for examining the exercise identity of college students in China.
