The purpose of this study was to explore whether posttraumatic growth moderates the effects of stress on depression and quality of life in cancer survivors. Data were collected from 173 cancer survivors in Seoul, Gyeonggi, Chungcheong, and Jeolla provinces. We used hierarchical regression to analyze the data. As the results, first, the interaction of stress and posttraumatic growth affected depression and quality of life. It means that even though the levels of stress are high when the levels of posttraumatic growth are high, the levels of depression are lower and the levels of quality of life are higher than posttraumatic growth being low. Second, the interaction of stress and posttraumatic growth affected two sub-factors of quality of life. We discussed the interventions to reduce depression and to increase quality of life.
