The Association between Relationship Satisfaction Concordance and Breast Cancer Survivors' Physical and Psychosocial Well-Being.

The purpose of this article is to examine the association of relationship satisfaction concordance between breast cancer survivors (BCSs) and their partners with matched controls on physical and psychosocial outcomes. Dyads of BCSs, age-matched controls, and partners were recruited as part of a larger, cross-sectional QOL survey study. Relationship concordance was measured by the ENRICH marital satisfaction score, with each dyad's score equaling the absolute value of the difference in satisfaction between survivor/control and their partner (lower score = greater concordance). Dependent variables for survivors/controls were social constraint, physical function, depression, fatigue, attention function, and sleep disturbance. Relationship satisfaction and concordance were used as the primary independent variables, while controlling for dyad category, race, education, income, and age within multiple linear regression models. The sample consisted of 387 dyads (220 BCSs, 167 controls). Relationship satisfaction concordance ranged from 0 to 53.4 (mean = 10.2). The BCS dyads had significantly worse concordance (11.1) than the controls (9.1) ( p = 0.050). Within the multiple regression models, lower concordance was significantly associated with increased social constraint ( p = 0.029), increased depression ( p = 0.038), and increased fatigue ( p = 0.006). Poor relationship satisfaction and concordance were significantly associated with poor physical and psychosocial outcomes. The maintenance of relationships should remain a focus through difficulties of cancer and into survivorship for survivors, partners, and providers.
