They were used to study romantic relationships and validated in that context but it is possible they could be used for other dyadic interpersonal relationships such as friends or family members.

Everyday kinds of choices where the impact on our lives is minimal.
Decisions that will not matter much the next day.
Choices such that we disagree but neither of us feels very strongly about the outcome.
When we disagree about an unimportant decision.
If we had to make a decision that might affect how happy we each are for just the evening but not after that.
When we want different things but neither of us will be upset if we do not get our way
