McDonalds vs Cronbach - Check the validity of a questionnaire with different response options

JorgeTT

Hello.

I am translating this The Young Spine Questionnaire - http://www.spoergeskemaer.dk/wp-content/uploads/YSQ_UK_v_1_1.docx

Responses options include "Yes/No" in some questions. Others have "never, frequently, once or twice". Other questions are a sort of a likert scale.

My doubts:

1) I can not Cronbach in this case, right? It would have be a questionnaire that give a total score/use a sort of likert scale in all questions?

2) Can I use McGonald's Omega to determine the validity of the questionnaire?

Thanks a lot,

Jorge

HI jorge,

I don't think this is the right place to ask these questions (as they are not Opensesame specific). I recommend you post it some other place on the web. Maybe research gate?

Thanks,

Eduard
