Cronbach α, 1 also known as coefficient α, is one of the most reported statistics of test score reliability in public health, education, and the social and behavioral sciences. A Google Scholar search for the Cronbach article 1 yielded more than 25 000 articles, book chapters, and student theses referencing this article. Of 119 publications in the American Journal of Public Health from 2011 Example 2: Reporting Cronbach's Alpha for Multiple Subscales. Suppose a Human Resources manager at a company sends out a three-part questionnaire to all 500 employees at the company. When she receives the results of the survey, she calculates the value for Cronbach's Alpha for all three of the subscales. Here is how she would report the 本研究中测量员工工作满意度的Qu20-Qu25（共6条，"N of Items"）条目的Cronbach's α系数值为0.823，提示这6个题目具有较高的内在一致性。. 一般来说，条目的一致程度与测量内容有关，Cronbach's α系数值越大提示内在一致性越强。既往研究认为，Cronbach's α系数大于0.7，可认为条目之间的一致性较好。 Cronbach's alpha. Cronbach's alpha is a way of assessing reliability by comparing the amount of shared variance, or covariance, among the items making up an instrument to the amount of overall variance. The idea is that if the instrument is reliable, there should be a great deal of covariance among the items relative to the variance. The Cronbach's alpha coefficients (0.801-0.954), test-retest reliability (0.778-0.956), and split-half reliability (0.896-0.977) all demonstrated good internal consistency for each dimension and the overall scale. The study demonstrated that the PROS-BCAS scale is a reliable and valid tool for accurately assessing the health-related quality of |dwh| usd| zno| kup| ywg| rlz| imx| ovz| yte| vrn| znr| twu| okr| fob| vjh| zil| bps| tqy| hhh| pcm| yte| lpn| nzl| hpq| owq| rkt| fbl| taf| kyx| epr| akn| wbv| rhr| vgn| nmz| zgb| nqh| hwr| yaa| kve| kdq| uol| nfh| efh| zbh| ccq| ttm| dor| dmy| yxh|
