Effect of Culture on Scales

#1
I am considering implementing a study asking respondents to rate several items on 1-10 scale. In America, I know the limitations of the scale.

However taking a global perspective, what is the appropriate scale to use; 1-10 in America, culturally, does not mean the same thing in other parts of the world.

I anticipate conducting the study with American, Canadian, Irish, and Japanese respondents. Does anyone know of any research on research that covers this. Then on the analysis end, how best to normalize these different scores using potentially different scales so that an apples to apples, so to speak, comparison/analysis can be conducted.

Your help is greatly appreciated :tup:
