Abstract

Background and Objectives: Little is known how coping self-efficacy (CSE) interacts with coping in dyad everyday life. The present study examined the moderating role of daily CSE in the relationship between coping and the next-day positive (PA) or negative (NA) affect in patient-caregiver dyads, following hematopoietic stem cell transplantation. Design: This intensive longitudinal study was conducted during the first 28 days after post-transplant discharge. Methods: Patients and their caregivers (N = 200) maintained daily diaries on CSE, coping strategies, and affect. Results: Daily CSE moderated daily coping–affect relationship: Positive emotion-focused coping increased PA in patients with higher than usual emotion-related CSE, whereas a buffering effect was found at lower than usual emotion-related CSE. A positive association between negative emotion-focused coping and NA in both patients and caregivers was stronger among those with lower than usual levels of emotion-related CSE. Higher than usual instrumental coping reduced NA in patients whose caregivers had higher than usual problem-related CSE, but increased NA for those whose caregivers had lower than usual instrumental CSE. Conclusion: The findings show that daily CSE contributes to the effectiveness of daily coping within dyad, confirming its significance in effective adaptation and the role in the dyadic coping process
