Understanding Society User Support

Hi -- I would be grateful for a bit of help in determining whether the variable EthID3 is asked of all relevant respondents in Wave 5 (relevant = EMBoost, GP Comparison, LDA, etc.). I can see that the question is in the Wave 5 questionnaire, but I want to make sure that it isn't asked only of new sample entrants. I've tried working this out via the Long Term Content Plan, but it isn't clear to me which "theme" it falls under -- it could be "Identity" (thus part of the Ethnic Identity module) but that theme is indicated on p. 6 as being asked in Waves 2 and 8.

My goal is to compare respondents' answers in Wave 2 and Wave 5; if it is asked in Wave 5 only of new entrants, I won't be able to do that.

thank you,
David
