Predicting Sleep Quality Based on Mindfulness among the Patients who Suffer from Irritable Bowel Syndrome (IBS): Investigating the Mediating Role of Self-Regulation and Rumination

Background and Objective: Some studies have investigated the quality of sleep among patients with irritable bowel syndrome (IBS); however, they are not comprehensive. The current study was conducted to predict quality of sleep among patients with IBS based on mindfulness, the mediating role of self-regulation, and rumination. Materials and Methods: This was a cross-sectional study in form of structural equation modeling (SEM). The samples included 231 patients with IBS, and the measures were Mindfulness, Self-regulation, Rumination, and Pittsburgh Sleep Quality Index (PSQI) scales. In addition, the SPSS and R software were used to analyze data. Results: Mindfulness, along with the mediating role of self-regulation and rumination could predict sleep quality among patients with IBS (P < 0.01), and the fit indices indicated the model fit. Conclusion: Mindfulness, rumination, and self-regulation had an important role in sleep problems among patients with IBS.
