SPSS does not have a procedure to perform Rasch analysis. Winsteps and Bilog are among the specialty packages that can perform a Rasch analysis directly. In a general sense, a Rasch analysis could be performed using any tool that can handle multi-level data with dichotomous outcomes and random effects, for example HGLM in the HLM package. But this excludes SPSS. Good luck.
