METHODS: A total of 243 couples in which the patients were lymphoma were recruited to complete Dyadic Coping Inventory, Locke-Wallace Marital Adjustment Scale for both. And Strategies Used by People to Promote Health, Fear of Progression Questionnaire-Short Form for patients; General Self-Efficacy Scale and Hospital Anxiety and Depression Scale for spouses. We used the statistical programs SPSS 20.0 and SPSS Amos 20.0 for data analysis. RESULTS: There were significant correlations between patient-spouse's dyadic coping and marriage quality scores. The patients' dyadic coping scores were significantly associated with their self-efficacy, fear of cancer recurrence scores, marriage quality, their spouse's self-efficacy, and marriage quality. The spouses' dyadic coping scores were significantly associated with their self-efficacy, anxiety, and marriage quality. The actor-partner interdependence mediation model analysis mediator effect of dyadic coping in the relationship between self-efficacy, psychological distress, and marriage quality had a good fit, with χ2 /df = 17.106, p = 0.194; root mean square error of approximation = 0.036; GFI = 0.992; CN = 243. CONCLUSIONS: For both patient and spouses, dyadic coping mediated impact of self-efficacy on marriage quality of themselves and their spouses, and individuals' dyadic coping mediated impact their psychological distress on marriage quality of themselves and spouses.
