alpha coefficient

According to the relationship between Alpha coefficient and homogeneous test, and the relationship among homogeneous test, the parallel test and the essential-τ equivalent test, these three tests, the paper analysis the limitation of using Alpha coefficient to evaluate the reliability of homogeneous test.

从α系数与同质性测验、平行测验和τ-等价测验之间的关系，分析了α系数作为测验同质性信度估计的局限性；

Cronbach's alpha was 0.905 for DIAS ( self-report), three subscale's alpha coefficient ranged from 0.743 to 0.861, criterion validity of boys and girls were 0.298 and 0.480 respectively.

DIAS（自评）的α系数为0.905，三个分量表的α系数分别为0.785、0.743和0.861，男女的效度系数分别为0.298和0.480。
