Thank you for your comment. More specifically, what I am looking for is a scale that taps into what could be conceptualized as symbolic threat (within the integrated threat theory). However, the measure needs to generic in the sense that it should tap into various kinds of threats to one's ethnic culture and be applicable across cultural differences.

There are variety scales about culture. However, I think the best indicator is to gathering some codes from that cultures and after categorizing it, make it as criteria for that.

maybe it's time to collect some contextual paradox for realizing that they have cultural root or not, somehow reaching from issues to solution.
