Dyadic coping in metastatic breast cancer

Area of Science:

• Psychosocial Oncology
• Couples Therapy
• Cancer Survivorship

Background:

• Metastatic breast cancer (MBC) presents unique stressors impacting patients and partners.
• Dyadic coping, a "we" approach, is crucial for managing shared stress and maintaining relationship quality.
• Understanding the role of dyadic coping in MBC is vital for supportive care.

Purpose of the Study:

• To prospectively evaluate the association between common dyadic coping and cancer-related distress.
• To examine the relationship between common dyadic coping and dyadic adjustment in couples with MBC.
• To differentiate effects on patients versus their partners.

Main Methods:

• 191 couples with MBC completed surveys at baseline, 3, and 6 months post-treatment initiation.
• Cancer-related distress measured using the Impact of Events Scale.
• Dyadic adjustment assessed with the short-form Dyadic Adjustment Scale.

Main Results:

• Common positive dyadic coping showed differential effects: partners reported slightly lower distress, while patients reported slightly higher distress.
• Common negative dyadic coping was associated with significantly greater distress for both, more strongly for patients.
• Increased positive and decreased negative dyadic coping mutually benefited patients and partners, enhancing dyadic adjustment.

Conclusions:

• Collaborative coping is essential for managing the stress of metastatic breast cancer.
• Interventions should focus on enhancing adaptive dyadic coping strategies for couples.
• Further research into couple interactions can inform supportive care for MBC.
