Aim. This paper presents a narrative interview procedure in a unique way, due to the presence of not one, but two narrators simultaneously. The narrative interview technique was presented in the context of the narrative-biographical method, and marital functioning was presented in the context of a systemic understanding of the family. Methods. The study was conducted using a narrative interview technique with married couples who rate their marriage as happy. The research focused on happiness in marriage and was conducted with a group of spouses who subjectively rate their marriage as highly satisfying. Results.

Otherwise, a joint interview would probably have been impossible, and certainly risky
