I am using the multilevel mixture IRT model, but I found responses having dichotomous scoring and partial credit scoring.

Could I use this model to analyze both types of responses in the same time?

Mplus does not yet incorporate the partial credit model. See, however,

Huggins-Manley, A.C. & Algina, J. (2015). The partial credit model and generalized partial credit model as constrained nominal response models, with applications in Mplus. Structural Equation Modeling: A Multidisciplinary Journal, DOI: 10.1080/10705511.2014.937374

although that is not multilevel mixture.

If the responses are mixed with dichotomous and polytomous data, for example, item 1 til item 6 are scored as 0 or 1, and item 7 til item 10 are score as 0,1,or 2.
Is it possible to use the multilevel mixture Rasch model to analyze the data with dichotomous and polytomous scores?
