I don't think I have done second-order EFA, instead I just did first-order EFA. Should I refer to the example 4.5 and 4.6 in the Mplus guide book for second-order EFA? Any suggestions for other reference would greatly appreciated. Thank you very much!
I asked because you implied that you had done a second-order EFA and therefore the second-order CFA should fit. Given the one second-order factor has no variance. It should not be included in the model.

Sorry about the confusion. I am considering to remove that second-order factor. Thanks!

I got another question. I read a very good discussion regarding fit indices for categorical outcomes at http://www.statmodel.com/discussion/messages/23/26.html?1244640406 posted 10 ages ago. I am carrying out SEM with a binary outcome variable using MLR. It seems that so far Mplus still does not provide fit indices for categorical outcomes. I am wondering there is any conclusion on that or there is any alternative way to diagnose model fit with categorical outcomes. Any suggestion and useful references are appreciated.
Chi-square and other related fit statistics are not available when means, variances, and covariances are not sufficient statistics for model estimation. These fit statistics are available for categorical outcomes with weighted least squares estimation.
