| Abstract text | Introduction Undergraduate students often experience poor sleep quality, which may adversely affect their physical health, cognitive functions, and academic performance. Previous research has uncovered a noteworthy association between sleep beliefs and sleep quality. Additionally, a relationship seems to exist between negative emotions and both sleep-related beliefs as well as sleep quality. However, it remains uncertain whether beliefs concerning sleep can impact sleep quality through negative emotions and the mechanisms involved. The objective of this study was to investigate the relationship among sleep beliefs, negative emotions, and sleep quality in undergraduate students. Methods A simple random sampling method was utilized to distribute three questionnaires to 864 undergraduate students [males = 629 (72.8%), age = 18.81 ± 1.00 years] in China. Individual negative sleep-related beliefs, negative mood, and sleep quality were measured by the Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16), Pittsburgh Sleep Quality Index (PSQI), and Depression, Anxiety, and Stress Scale-21 (DASS-21), respectively. The Cronbachs alpha coefficient of the DBAS-16 and PSQI are 0.91 and 0.80, respectively. The Cronbachs alpha coefficient of the DASS-21 is 0.95, and the Cronbachs alpha coefficients of the depression, anxiety, and stress subscales are 0.88, 0.82, and 0.88, respectively. With SPSS 27.0, descriptive, correlational, and regression analyses of the data were carried out. The mediation model was tested using Hayes PROCESS v3.5 application. The bias-calibrated nonparametric percentile Bootstrap method was used to examine the significance levels of mediated effects. Results There were significant negative correlations among sleep beliefs, negative emotions, and sleep quality for each pair of variables. Each of the three sub-dimensions of negative emotions (depression, anxiety, and stress) was significantly positively correlated with sleep quality (r=0.450, p=0.01; r=0.463, p=0.01; r=0.482 p=0.01). Positive correlations exist among each pair of variables within the sub-dimensions of depression, anxiety, and stress. Notably, sleep beliefs have both direct negative predictive effects on sleep quality (ß = -0.147, p< 0.001) and indirect influences through three pathways: independent mediation by depression (ß = -0.186, p< 0.001), anxiety (ß = -0.180, p< 0.001), and stress (ß = -0.199, p< 0.001). Additionally, they operate via two chain-mediated pathways involving depression with stress (ß = -0.052, p< 0.001), and anxiety with stress (ß = -0.043, p< 0.001). Discussion Depression, anxiety, and stress independently mediate the association between undergraduate students sleep beliefs and sleep quality, with additional chained mediation involving depression and stress, anxiety and stress. |
