Mediating and Moderating Effects of Uncertainty on the Relationship between Family Function, Self-Care, and...

Uncertainty in cancer survivorship poses a substantial challenge to survivors' coping mechanisms and psychological well-being. This study investigated the intricate interplay among family function, uncertainty, self-care, and depression in this context, with a primary focus on discerning the mediating and moderating roles of uncertainty in the relationship between family function, self-care, and depression among blood cancer survivors. Cross-sectional data from 147 survivors in South Korea underwent analysis using descriptive statistics, Pearson's correlations, and the PROCESS macro in SPSS version 26.0. The results revealed that family function significantly predicted both self-care and depression. Notably, uncertainty mediated the relationship between family function and these outcomes. Furthermore, the impact of family function on depression was moderated by uncertainty, indicating a relatively weaker association in survivors facing higher uncertainty levels. This study contributes valuable insights by elucidating the role of uncertainty in regulating how family function influences self-care and depression among survivors of blood cancer. It emphasizes the critical need to enhance family function and alleviate uncertainty for the improved adjustment of cancer survivorship. The findings underscore the importance of targeted support for individuals grappling with different levels of uncertainty, aiming to prevent or mitigate depressive symptoms through the reinforcement of family function.
