Abstract

Objective: The purpose of this study was to evaluate the effectiveness of post-traumatic growth (PTG) model-based intervention to improve positive psychological traits in Chinese breast cancer patients. Design: A randomized control trial of a psychological group intervention based on PTG model. Methods: The Clinical Trial was registered on 17 August 2019 at Chinese Clinical Trials.gov with Registration number ChiCTR1900025264. A total of 92 patients with breast cancer were recruited. The participants were randomly assigned to the experimental group (n = 46) and the control group (n = 46). A six-session psychological group intervention based on PTG model was implemented in the experimental group, and a six-session health education was implemented in the control group. The outcomes were measured at baseline (pre-intervention), 3 weeks, 6 weeks after the intervention. The primary outcome was posttraumatic growth assessed by the Chinese version of the Post-Traumatic Growth Inventory (PTGI); Secondary outcomes included psychological resilience, family resilience, rumination, and self-disclosure. Results: A total of 87 patients with breast cancer completed this study, including 44 patients in the experimental group and 43 patients in the control group. There was no significant difference in baseline data of breast cancer patients between the two groups except for the treatment regimen (p > 0.05). The two groups were compared after the intervention; the interaction effects between the total scores of posttraumatic growth, family resilience, and self-disclosure and the time term were statistically significant (p < 0.05), indicating that the trend of change in total scores of post-traumatic growth, family resilience, and self-disclosure differed between the experimental and control groups over time, and the scores improved in the experimental group were significantly higher than those in the control group. The comparison of psychological resilience and total score of rumination at each time point was statistically significant (p < 0.05), indicating that group intervention based on the PTG model could improve the psychological recovery ability and rumination level of the experimental group. Conclusion: The psychological group intervention based on the PTG model significantly improved post-traumatic growth, family resilience, and self-disclosure in patients with breast cancer. However, the impact on psychological resilience and rumination was relatively small. Long-term intervention is needed to further test the effect of the PTG model on psychological resilience and rumination.
