Distinct dyadic coping profiles in Chinese couples with breast cancer.

Conceptualizing cancer as a dyadic stress provides new insight into how stress impacts couples with breast cancer. The present study aimed to identify subgroups with distinct dyadic coping profiles in a sample of Chinese couples with breast cancer and to determine how these subgroups differed in terms of demographic and clinical characteristics in addition to marital adjustment outcomes. Using convenience sampling, a cross-sectional survey was conducted. Couples with breast cancer completed the general information questionnaire, the Dyadic Coping Inventory, and the Locke-Wollance Marital Adjustment Test. The modeling was performed using a latent profile analysis to identify the dyadic coping subgroups. Parametric and nonparametric tests were applied to examine between-group differences across the identified classes. The analytical results supported a three-class solution of dyadic coping groups: high (27.4%), medium (32.2%), and low (40.4%). Between-group differences were found in educational background, number of children, postoperative time, and type of surgery. Most couples reported low levels of dyadic coping. The couples with an educational level of primary school or below, with one child or who were childless, and who had undergone breast preservation surgery within the past year were more likely to belong to the low dyadic coping group. When supporting couples with breast cancer, it is essential to assess several demographic and clinical risk factors in addition to the marital adjustment level to identify high-risk subgroups that warrant intervention.
