Hi, I´m running a CFA-model for categorical variables using the WLSMV estimator. Is it possible to get the confidence interval for RMSEA? Do you know if there is a simulation study dealing with the WLSMV estimator and items with 7-point likert scale? I only read some articles about the appropriateness of the WLSMV estimator for different sample sizes dealing with 5-point likert scale items. Thanks a lot for your help. Anna |

We do not provide the confidence intervals for RMSEA with categorical outcomes. I believe these have recently been developed and we may add them in the future. The same principles apply to 7-point scales as 5-point. If they do not have floor or ceiling effects, they can be treated as continuous. |

Hello, I'm wondering if you have any update on this issue, whether a confidence interval for RMSEA with categorical outcomes is now available in MPlus (I'm currently running version 4.1), or if there is a reference available. Thanks! Mark |

These confidence intervals have not yet been developed. |
