Mediating role of resilience between family functioning and quality of life in patients with advanced colorectal cancer

Objective: To better understand the relationship between family functioning, resilience, and quality of life (including physical and mental component score, PCS and MCS) in patients with advanced colorectal cancer (CRC) to predict and improve their quality of life.Methods: A cross-sectional study was conducted in which a total of 165 patients with advanced colorectal cancer participated in a one-time survey. Measures included the Family Functioning Assessment Device, the 10-item Connor-Davidson Resilience Scale, and the SF-12 Health Survey Assessment Scale. The data analysis methods included descriptive analysis, pearson's correlation analysis, t-tests, and nonparametric tests.Results: Of the patients with advanced CRC, 47.27% and 72.73% had moderate or low mental and physical health components, respectively. The results indicated that in patients with advanced CRC, family function was negatively correlated with resilience (p < 0.01), family functioning was negatively correlated with MCS (p < 0.01), and resilience was positively correlated with PCS (p < 0.05) and MCS (p < 0.01). The mediating analysis revealed that family functioning regulated MCS through resilience (effect value = 13.17%).Conclusions: Our findings suggest that the MCS of patients with advanced CRC is influenced by both family functioning and resilience. PCS in patients with advanced CRC appears to be influenced by resilience but not by family functioning.
