Structural Equation Model of Pain Management Based on Rumination, Positive and Negative Emotional Regulation Mediating Resilience in Women With Breast Cancer

Background: breast cancer is the second leading cause of cancer death in women, accounting for approximately 21% of all cancers worldwide.objective: the present study aimed to assess the pain management model based on rumination, as well as positive and negative emotional regulation, with the mediating role of resilience in women with breast cancer.method: the present study was conducted based on a correlational design (structural equation modeling). the statistical population of the present study was all women with breast cancer who were referred to medical centers (private and public hospitals and clinics) in tehran in 2019. the sample size was calculated at 273 patients according to morgan's table who were selected via simple random sampling. rumination response questionnaires, positive and negative emotional regulation, resilience, and pain management were used to measure the variables of the study. the obtained data were analyzed in spss software and lisrel using spearman correlation coefficient and path analysis.results: based on the results, resilience had a mediating role in the indirect effect of positive emotional regulation on activity enhancement (p<0.01). nonetheless, resilience played no significant mediating role in the relationship between positive regulation. moreover, the results pointed to the significant indirect effect of negative emotional regulation with the mediating role of resilience on activity enhancement (p<0.01). however, resilience had no significant mediating role in the relationship between negative regulation.conclusion: as evidenced by the obtained results, it can be concluded that the pain management model based on rumination, as well as positive and negative emotional regulation, was fitted with the mediation of resilience in women with breast cancer.
