The Effects of Stress on Quality of Life in Cancer Patients: Focusing on the Moderating Effects of Post-traumatic Growth

Abstract

Improving and maintaining the quality of life had always been the objective of treatment as well as intervention for chronic cancer. Because of this, understanding predictive factor their correlation to quality of life has become an important issue in the medical field. However, previous research attempts were limited to pathologic models focusing on serious pain that cancer patients go through. This study was aimed at revealing the moderating effects of post-traumatic growth on the quality of life of cancer patients under severe stress. After conducting a survey of 191 cancer patients, stress and post-traumatic growth are found to have direct effect on their quality of life. Another finding was that post-traumatic growth can control the negative effects on quality of life. In consideration of its multi-dimensionality, quality of life was broken down into physical, functional, social and emotional aspects. As the result of careful examination, it has been concluded that post-traumatic growth shows that it only has moderating effects on emotional quality of life. Based on this result, it has been concluded that efforts should be made to promote post-traumatic growth which is a strong predictor of lessening stress for better quality of life for the cancer patients. Through this intervention, it will be possible to contribute to raising the quality of life of cancer patients. With such implications regarding the research, advice for the next step of research had been suggested.
