Background: This study was conducted to determine a hypothetical model for the factors affecting the quality of life of postoperative colorectal cancer patients.
Methods: We collected data from 209 patients that was analyzed using SPSS 22.0 and AMOS 25.
Results: Predictive variables of the hypothesis model included an exogenous variable, social support, as well as endogenous variables self-efficacy, symptoms, health promotion behavior, and quality of life. Testing of the correction model showed that significant paths directly affecting quality of life of patients after colorectal cancer surgery included health promotion behavior, symptoms, and self-efficacy and also showed an explanation power of 58.7%. Social support was found to have a significant impact on the quality of life indirectly through self-efficiency.
Conclusions: To improve the quality of life of colorectal cancer patients, it is necessary to develop a nursing intervention program that strengthens patients' health promotion behaviors to alleviate their symptoms and improve their social support and self-efficacy.
