Evidence shows that resilience is crucial to maintain psychological well-being and quality of life in the face of stress and adversity. However, the relationships between resilience and psychological well-being and factors associated with quality of life in Hong Kong Chinese parents of children with cancer are underexplored. This study aimed to examine the interrelationships among resilience, ways of coping, psychological well-being, and quality of life among Chinese parents of children with cancer, and identify factors associated with their quality of life. A cross-sectional study was conducted with 119 Chinese parents of children with cancer at the Hong Kong Children’s Hospital between January 2020 and March 2022. Parents’ resilience level, ways of coping, depressive symptoms, state anxiety scores, perceived social support, and quality of life were assessed. Participating parents (n= 119) included 98 mothers (82.4%) and 11 parents were from single-parent families (9.2%). Almost half (47.9%) of the parents were potentially at risk for depression. The results showed that participants from single-parent families reported statistically significantly lower levels of resilience (p< 0.001), more depressive symptoms (p< 0.001), and poorer quality of life (p< 0.001) than those who lived with their partners (married). In addition, parents who adopted problem-focused coping strategies reported statistically significantly higher levels of resilience (p< 0.001), fewer depressive symptoms (p< 0.001), and better quality of life (p< 0.001) than those who adopted emotion-focused coping strategies. A multiple regression analysis revealed that resilience (p< 0.001) was associated with quality of life among parents of children with cancer. This study provides further support that resilience is an important factor associated with quality of life in parents of children with cancer. Assessing resilience in parents is an important prerequisite for designing appropriate interventions to increase their resilience and enhance their quality of life.
