Posttraumatic growth (PTG) is defined as 'positive psychological change experienced as a result of a struggle with highly challenging life circumstances'. The purpose of this study was to identify the level of PTG and its correlates in Korean patients with breast cancer.

A sample of 120 participants was recruited from outpatients, who had successfully completed primary treatment of breast cancer at a university hospital., Data were collected from June to December, 2014 using Posttraumatic Growth Inventory, lllness Intrusiveness Rating Scale, Cancer Coping Questionnaire, Revised Life Orientation Test and The Multidimensional Scale of Perceived Social Support.

Total score for the PTG was 79.18±17.54 in patients surviving breast cancer. Bivariate analyses indicated that PTG was positively associated with having a religion, perceived social support, greater optimism, cancer coping, and illness intrusiveness. Results of the regression analysis showed that cancer coping (β=.29, p=.001), optimism (β=0.28, p=.001) and illness intrusiveness (β=0.17, p=.037) were statistically significant in patients' PTG.

The research findings show that the variables of cancer coping, optimism and illness intrusiveness significantly explain PTG and these psychological variables can be used to provide improvement in PTG for patients with breast cancer
