Abstract:

The aim of the study was to test three mediation and a moderation models in order to investigate the mediating role of coping styles and both mediating and moderating roles of perceived social support between dispositional hope-posttraumatic growth/PTSD relationships among postoperative breast cancer patients. Accordingly, it was hypothesized that 1) Problem-focused coping styles (PFC) would mediate the relationship between dispositional hope and posttraumatic growth among postoperative breast cancer patients. 2) Emotion-focused coping style (EFC) would mediate the relationship between dispositional hope and posttraumatic stress disorder among postoperative breast cancer patients. 3) Perceived social support would mediate the relationship between dispositional hope and posttraumatic growth among postoperative breast cancer patients. 4) Perceived social support would moderate the relationships between dispositional hope and posttraumatic growth among postoperative breast cancer patients. The study was conducted with 73 postoperative breast cancer women (mean age = 44.44, SD = 7.43) who were undergoing postoperative chemotherapy and radiotherapy. Participants were from different cities but receiving treatment from Dr. Abdurrahman Yurtaslan Ankara Oncology Education and Research Hospital. Measurements were applied orally to participants. According to results of the study, PFC did not mediate the relationship between dispositional hope and PTG and its subscales. Similarly, the relationship between dispositional hope and PTSD and its subscales was not mediated by EFC. Beside, perceived social support and its sources did not mediate the relationship between dispositional hope and PTG and its subscales. However, perceived social support and perceived social support from friend moderated the relationship between dispositional hope and PTG. Results, limitations, clinical implications of the study and directions for future studies were discussed in the light of the literature.
