Dyadic interdependence on affect and quality-of-life trajectories among women with breast cancer and their partners

This study explored interdependence on quality-of-life factors for women with breast cancer and their partners. Multiple theoretical perspectives predict that the emotional distress experienced by women with breast cancer would be shared by their partners. To test these predictions, 48 women with breast cancer and their partners (husbands, daughters, friends, or other relations) participated in a three-wave, 10- week, longitudinal study. Quality-of-life (QOL) indicators (depressive symptoms, positive and negative affect, and stress) were measured in both women and their partners. Baseline data revealed significant partner effects from stress and negative affect in women with breast cancer to their partners’ depression. Analysis of QOL rates and directions of change over time revealed that the QOL was on a similar trajectory. As the emotional well-being of women with breast cancer improved or deteriorated, their partners’ well-being changed also.
