description OBJECTIVES: Students of medical sciences are exposed to many emotional and mental problems. In light of the importance of sleep quality in learning and liveliness, this study was conducted to examine the relationship between psychological variables (stress, anxiety, and depression) and sleep quality of students. DESIGN: This research is a cross-sectional analytical study, where all students studying at Fasa University of Medical Sciences in 2012-2013 year were selected. To examine the students' stress, anxiety, and depression values, the standardized 21-item DASS-21 was used, and to examine their sleep quality, Pittsburgh Sleep Quality Index (PSQI) was used. RESULTS: The results of the study demonstrated that 73% of the students have moderate and severe stress, and 46.4% of them have PSQ scores ≥ 5. The students' mean sleep quality score was 4.65 ± 2.37, and their stress score was 8.09 ± 5.14. A statistically significant relationship was found between the students' stress levels and sleep quality (P < 0.001). CONCLUSION: The high stress levels decrease students' sleep quality. High stress levels and also the significant relationship between stress value and decrease in students' sleep quality call for more attention to and care for students' emotional and mental issues and timely proper interference on the part of authorities.
