克隆巴赫大于0.6或者大于0.7都是可以的,我能找到的文献是这个:
gbo A A. Cronbach’s Alpha: Review of Limitations and Associated Recommendations[J]. Journal of Psychology in Africa, 2010, 20(2): 233-239.
原文:
he level at which alpha should be accepted or not abound in literature (Charter, 2003). Nunnally’s (1970; 1978) recommendation is by far more influential. Nunnally recommended that alpha of .70 can be accepted in early stages of research exploration, and .80 and .90 for basic and applied research.
翻译:
接受或不接受alpha值的标准在文献中比比皆是(Charter, 2003)。Nunnally (1970; 1978) 的建议迄今为止最具影响力。Nunnally建议,在研究探索的早期阶段,可以接受.70的alpha值,而基础研究和应用研究则分别接受.80和.90的alpha值。
