Social constraints on disclosure predict daily well-being in couples coping with early-stage breast cancer.

According to the social-cognitive processing model (Lepore, 2001), social constraints on disclosure can limit an individual's ability to communicate openly with others and consequently have negative effects on psychological adjustment, especially in the context of stressful experiences such as the diagnosis and treatment of cancer. The goal of the present study was to examine the influence of social constraints on daily event sharing, individual well-being, and relationship well-being in couples coping with breast cancer. Forty-five patients recently diagnosed and treated for early stage breast cancer and their spouses reported perceptions of spousal constraints on patient disclosure and completed a 7-day electronic diary. Analyses revealed that patient-reported social constraints, independent of the spouse's report, were linked to reduced patient sharing of both cancer-related and other important daily events. Patient and spouse perceptions of social constraints, independent of their shared consensus, predicted reduced daily individual well-being indexed by self-esteem and negative affect, as well as reduced daily relationship well-being indexed by relationship happiness and intimacy. Moreover, many of the aforementioned effects on daily well-being remained after controlling for global marital quality. Overall, these findings reveal that individual perceptions of social constraints have a negative influence on both patient and spouse daily well-being outcomes.
