摘要
本文针对WISC -CR的二因子和三因子模型 ,以 2 0 1位 6至 7岁小学生为对象 ,运用多元概化理论的方法研究了其总信度和各亚因子的测量信度。研究发现 :(1)二因子模型下各亚因子与总测验的测量信度都比较高。但当它被作为测量言语理解、知觉组织和抗干扰三个因子的量表时 ,第 3个因子的测量信度过低 ,且不易得到改善。这表明不宜用它来测量抗干扰的能力 ;(2 )该量表不宜作为标准参照性测验来使用 ,因为其测量信度无法得到保障。此外 ,文章还展示了评价一个成套测验总信度及其亚能力因子信度的MGT方法 。
In this study,we used the Multivariate Generalizability Theory (MGT) to analyze the WISC CR Scale.Random effect variance and covariance components were estimated in the G study.Generalizability coeffecients for each latent factor of the scale and composite generalizability coefficients for the whole scale were estimated in the subsequent D study for both the 2 Factor model and 3 Factor model.The results showed that the generalizability coefficient (reliability) was acceptable to the whloe scale,the Verbal Comprehension factor and the Perceptual Organization factor,but not to Freedom from the Distractibility factor.
