Background: Women's health is the key to the development of society, and attention to its physical, psychological, and social aspects leads to improved daily functioning. Premenstrual dysphoric disorder can have a profound impact on women's personal health and family and professional relationships. Therefore, it is very important to examine the variables affecting this disorder.
Aim: The main objective of this study was to investigate the effect of emotion regulation, self-compassion, and quality of life on the symptoms of premenstrual dysphoric disorder, considering the mediating role of the self-silencing variable.
Methodology: The statistical population of this study was 405 female students of Shiraz University at different educational levels, who were selected using the multi-stage cluster sampling method. In this study, the structural equation modeling method with the partial least squares approach using Smart PLS 4 software was used to investigate the effect of variables on the premenstrual dysphoric disorder variable and also to investigate the mediating role of the self-silencing variable for independent variable
Conclusions: Based on the results obtained, the emotion regulation, self-compassion, and quality of life self-silencing variables affected the premenstrual dysphoric disorder variable by -0.189, -0.295, -0.195, and 0.259, respectively, and all of these relationships were significant at the 95% level. Also, the self-silencing variable only played a mediating role in the relationship between self-compassion and PMDD. The results showed that since the relationship between emotion regulation, self-compassion, and quality of life variables was inversely related to PMDD, an increase in these variables was associated with a decrease in PMDD symptoms. The opposite is true for the self-silencing variable.
