Dear sir, I think that a good point to answer your question about fit indices is from the following link http://davidakenny.net/cm/fit.htm. But you must have in your mind that sample size is a good reason when you have problems with some of fit indices.

卡方比小于3就行，专业点的会要求小于2，其实你说的那几个不达标的指标，是说明你的模型有点复杂了，但是复杂归复杂，适配才是前提，因此有的杂志就不关注那几个“简约指标”。
