Self-disclosure and reproductive concerns among breast cancer female patients: the chain mediation model of couples' cancer-related communication problems and relationship intimacy.

Abstract

Purpose: Reproductive concerns are prevalent in the female breast cancer patient population and increase existential distress. Although self-disclosure significantly correlated reproductive concerns, the exact mechanism of action is unknown. Based on previous theoretical studies on couples' cancer-related communication problems and intimacy in couples, this study constructed a chain mediation model to investigate whether the two variables mediate the relationship between self-disclosure and reproductive concerns.

Methods: A cross-sectional survey was conducted from August 2023 to July 2024 at Jiangxi Cancer Hospital. A total of 280 female breast cancer patients completed the Distress Disclosure Index, Couples' Cancer-Related Communication Problems Scale, Quality Relationship Index, and Reproductive Concerns After Cancer Scale. Data description and Pearson's correlation analysis were performed through SPSS 26.0 software. Serial mediation effect analysis and testing were performed through Hayes' Process 4.1 program.

Results: Self-disclosure was found to be negatively associated with reproductive concerns and couples' cancer-related communication problems, but positively associated with intimacy. After controlling for sociodemographic variables, including age, matrimonial, number of children, and hormone receptor, the direct effect of self-disclosure on reproductive concerns was significant (Effect =  - 0.320; 95% CI, - 0.465 to - 0.178). In addition, three other indirect pathways of action were also significant: (1) through couples' cancer-related communication problems (Effect =  - 0.113; 95% CI, - 0.181 to - 0.045), (2) through intimate relationships (Effect =  - 0.110, 95% CI - 0.187 to - 0.043), and (3) through the chain-mediated effects of couples' cancer-related communication problems and intimacy (Effect =  - 0.025; 95% CI, - 0.054 to - 0.007). The total indirect effect of the three pathways of action was 43.66%.

Conclusions: Self-disclosure not only directly affects reproductive concerns in female breast cancer patients, but also indirectly through couples' cancer-related communication problems and intimacy, as well as sequential mediation of the two. Interventions targeting the above factors can help promote self-disclosure in female breast cancer patients, reduce couples' cancer-related communication problems, and improve intimacy, thereby alleviating reproductive concerns after cancer.
