Factors Related to Resilience, Anxiety/Depression, and Quality of Life in Patients with Colorectal Cancer Undergoing Chemotherapy in Japan.

OBJECTIVE

This study clarifies the relationship between resilience and anxiety and depression, quality of life (QOL), and other related factors that influence colorectal cancer patients undergoing chemotherapy.

METHODS

This cross-sectional study focused on outpatients with colorectal cancer undergoing chemotherapy. A questionnaire including the Connor-Davidson Resilience Scale, Hospital Anxiety and Depression Scale, the MOS 12-item Short-Form Health Survey, and items based on a literature review was administered between August 2019 and August 2020. SPSS version 26 was used for data analysis. Correlation analysis and -test were applied. In addition, Amos version 26 was used and structural equation modeling was applied to create a causal model.

RESULTS

A total of 121 participants (94.5%) were included in the study. The goodness of fit (GFI) of the causal model was GFI = 0.94, adjusted GFI = 0.906, comparative fit index = 0.997, and root mean square error of approximation = 0.011. Resilience had a negative effect on anxiety and depression and a positive effect on QOL. Depression had a negative effect on QOL.

CONCLUSIONS

The results of this study indicate that resilience is a predictor of anxiety, depression, and QOL in colorectal cancer patients undergoing chemotherapy. Therefore, I believe that it is important to enhance resilience in order to maintain and improve patients' mental health and QOL. In addition, since resilience was affected by cancer metastasis and the presence of metastasis was a predictor of resilience, it is a challenge to explore interventions to enhance resilience, especially in patients with metastasis.
