摘要: 如果有两个成套的心理测验X和Y,分别由p和q个子测验组成,则它们之间的效度系数可以用ρ_(XY)=(1/r)sum from i=1 to r(λ_i)来度量,这里的λ_i是矩阵M=V_(YY)~+V_(YX)V_(XX)~+V_(XY)的第i个非零特征根。这样定义的广义的效度系数ρ_(XY)在p=q=1或p=1,q>1时就是通常的心理测验中的效度系数。这个ρ_(TT)还可以作为一个成套测验T之信度系数的度量。文章给出了一个实例。

Abstract: If two series of psychological tests X and Y involve p and q subtestsseparately, we can take ρ_(XY)=1/r sum from i=1 to r λ_i as the validity coefficient betweenX and Y, where λ_i is the ith nonzero characteristic root of matrixM=V_(YY)~+V_(YX)V_(XX)~+V_(XY). When p=q=1 or p=1, q>1, the generalized correlationcoefficient ρ_(XY) is just the ordinary validity coefficient of psychologicaltests. This ρ_(TT) may be a measurement of the reliability of series test T.A practical example is in the paper.
