The Quality of Marriage Index (QMI) is a 6-item measure that asks participants to report the extent to which they agree or disagree with global statements regarding the quality of their relationship. The QMI uses items from the Partner Communication Scale (PCS) developed by Norton & Montgomery.
1. We have a good relationship
2. My relationship with my partner is very stable
3. Our marriage is strong
4. My relationship with my partner makes me happy.
5. I really feel like part of a team with my partner.

6. All things considered, what is the degree of happiness in your relationship?
10-point Likert scale
