Associations of perceived and common dyadic coping with self-care in older couples with cardiovascular disease: A dyadic analysis

Dyadic engagement of patients and caregivers in self-care is essential for management of heart disease. However, little is known how dyadic coping at individual and partner levels is associated with self-care in couples living with cardiovascular disease.This study examined whether dyadic coping at self, partner, and common levels was associated with patients' engagement in self-care and spouses' contribution to self-care in older couples living with cardiovascular disease.In this cross-sectional study, 288 older patients and spouses were recruited from outpatient heart clinics in Qazvin, north of Iran. Data were collected using the Dyadic Coping Inventory, the Self-care of Coronary Heart Disease Inventory, and the Caregiver's Contribution to Self-care of Coronary Heart Disease. Dyadic data were analyzed using the actor-partner interdependence model.The results showed that patients' engagement in self-care maintenance was associated with partner dyadic coping in patients, self and common dyadic coping in spouses. Patients' engagement in self-care monitoring was only associated with self dyadic coping in spouses. Dyadic analysis also showed that self-care confidence in patients was only associated with by partner dyadic coping in spouses.This study revealed that self-care was associated with dyadic coping employed by each member of the dyad at self, partner and common levels. Findings of this study suggest that perceived and provided levels of dyadic coping can be employed for maintaining or restoring self-management in older couples living with cardiovascular disease.
