Note. Approximately 2.5 h following the baseline blood draw, each partner completed the 8-minute relived emotion task, in randomized order balanced by sex, and rated their mood after each turn. Approximately 40 min after the end of the first disclosure and 30 min after the second disclosure, both partners provided another blood sample. Following an unstructured interview to identify the most important areas of disagreement in their relationship, the couple discussed one or two marital problems for 20 min then rated their mood. The final blood draw was taken 5 min after the end of the marital conflict discussion, 80–90 min after the disclosures.
