Hi,

I analyzed a data using CFA with Mplus and then analyzed it using Rasch model(1PL) with WINSTEPS. However, I heard that CFA in Mplus is similar to a two parameter IRT model. So, did I make a mistake?

Thank you in advance.

If you want a Rasch model in Mplus, you should hold the factor loadings equal and set the metric of the factor by fixing the factor variance to one.
