The need to understand PTG in relation to actual changes in an individual’s life hasrecently been raised. Little is known about the role of social support in the experience of positive outcomes. Thepurpose of this study is to investigate the role of perceived social support in enhancing PTG in cancer patients.This study involved 105 cancer patients. The data were collected using a questionnaire that determined thesocio-demographic features, posttraumatic growth inventory (PTGI) and perceived social support.
