[Rasch] Measurement invariance

Dear Anthony,
Surely you have equivalent items in two language versions? If so, you treat them as "common" items. WINSTEPS provides an analysis. B&F2, Chap 5 describes a method…common item linking…and provides an XL spreadsheet.
Does that help?

Subject: [Rasch] Measurement invariance

Dear all,
I have data for a scale and data for its translated version in another language. I want to ckeck measurment invariance across languages.
There are no items or bilingual persons shared in the data.
I was advised to use CFA and SEM or more sophisticated methods such as ESEM.
I am wondering if there’s a technique within RM to investigate measurement invariance for my scale.
Thanks for your help.
Anthony
