The relationship between rumination and sleep quality in patients with major depressive disorder

Introduction: Sleep disorders one of the problems of patients with depression is that they may be associated with a number of factors, such as rumination. Aim: The aim of this study was to investigate the relationship between rumination and sleep quality in depressed patients. Method: The present study was a descriptive-correlational study. A simple random sampling method was used to select 160 patients with major depressive disorder at Farshchian Hospital in Hamedan in 2017. Pittsburgh sleep questionnaire was used to collect data. Data were analyzed using descriptive and inferential statistics (pearson and spearman correlation coefficient) and SPSS 23 software. Results: The correlation between rumination and sleep quality in patients with major depressive disorder admitted in Farshchian hospital in Hamadan showed that Pearson correlation coefficient test showed a significant and direct relationship with 0.476 between rumination and sleep quality. So people who scored higher on the sleep quality questionnaire actually had lower sleep quality because of the reverse score. Data analysis showed that there was a significant relationship between rumination and sleep quality (r = -0.476, p = 0.001). Conclusion: The present study showed that there is a significant relationship between rumination and sleep quality in depressed patients and rumination leads to decreased sleep quality in patients. In depressed patients, sleep quality is more important and it is necessary to improve their health through strategies such as rumination therapy.
