I interviewed married couples--separate interviews with each partner and one with both of them together, so three interviews per couple. I want to compare the combined responses of husbands and wives, that is, the husbands' responses in both their individual and couple interviews and the wives' responses in their individual and couple interviews.

I want to count and compare husbands' and wives' responses on several topics. In the conjoint couple interviews, I coded the responses of the husbands and the wives on these topics. How do I combine these with their responses from their respective individual interviews?
