Common dyadic coping and its congruence in couples facing breast cancer: The impact on couples' psychological distress

Abstract Objective Psychological distress is prevalent in couples facing breast cancer. Couples often deal with breast cancer as a unit instead of as individuals. Couple's dyadic coping is important for their adjustment to breast cancer; however, little is known about how couple's coping congruence influences their distress. This study examined how common dyadic coping (CDC) and coping congruence impact psychological distress in couples facing breast cancer. Methods Baseline data were analyzed from 343 women with recently diagnosed early‐stage breast cancer and their partners who participated in a randomized clinical trial. Psychological distress was indicated by depressed mood and state anxiety. Common dyadic coping was measured by a self‐report scale. Coping congruence was assessed by the absolute difference between a woman's and her partner's CDC scores. Results Higher CDC scores were associated with lower psychological distress in both women and partners. In the CDC subscales, women who suffered less scored higher on open communication, sharing a positive outlook, and lower on avoidance coping. Partners who suffered less scored higher on open communication, sharing a positive outlook, spending time talking, and lower on avoidance coping. Greater congruence in CDC was associated with lower psychological distress in women and their partners. Congruence in sharing a positive outlook benefited both members of the dyad; congruence in avoidance coping significantly benefited patients; congruence in open communication significantly benefited partners. Conclusions CDC and its congruence in specific areas have potential benefit to couple's psychological distress when facing breast cancer. Health care providers could consider enhancing couple's CDC and coping congruence to improve their adjustment.
