Background: The physical and mental impacts of breast cancer diagnosis on women are substantial. Several studies have investigated the negative mental health effects of breast cancer. However, in recent years, there has also been growing interest in post-traumatic growth, a positive response to stressful events. Considering positive psychology focuses on such virtues, proactive coping theory was chosen as a theoretical guide. This study investigates how breast cancer patients' post-traumatic growth is associated with proactive coping and mental well-being.
Methods: A self-administered questionnaire survey was conducted with 80 breast cancer patients aged 20-70 years attending an outpatient clinic. The survey was conducted using the Posttraumatic Growth Inventory-Japanese version (PTGI-J), Proactive Coping Inventory-Japanese version and the Japanese version of the General Health Questionnaire. Single regression and multiple regression analyses with PTGI-J as the dependent variable were performed.
Results: The multiple regression analysis extracted proactive coping (P = 0.006), emotional support seeking (P = 0.004) and avoidance coping (P = 0.001) as factors associated with post-traumatic growth in breast cancer patients.
Conclusions: These results suggest that using proactive coping for conflicts caused by a breast cancer diagnosis and temporary avoidant coping for daily stresses during the treatment process may enhance post-traumatic growth while preventing deterioration in mental well-being. Additionally, seeking emotional support is important for post-traumatic growth.
