Sleep quality and rumination: the role of resilience as a mediator
摘要
Emerging adults represent a uniquely developmental stage that is vulnerable to the consequences of inadequate sleep quality, due to ongoing brain maturation processes. Rumination has been found to negatively impact sleep quality, whereas resilience is increasingly recognized as a protective factor for both sleep quality and rumination. This study investigated the relationship between sleep quality and rumination, as well as the mediating role of resilience in emerging adults from Uruguay. A sample of 835 participants (mean age 21.52 ± 2.23) completed a web-based survey that included the Socioeconomic Status Index, the Pittsburgh Sleep Quality Index, the Ruminative Responses Scale, and the Connor and Davidson Resilience Scale. Linear regression models and mediation analysis were used to analyze the data. Results indicated that higher levels of rumination were associated with poorer sleep quality (β = 0.107, SE = 0.007, p < 0.001), and higher levels of resilience were associated with better sleep quality (β=-0.069, SE = 0.007, p < 0.001). Moreover, rumination decreased as resilience increased (β=-0.478, SE = 0.058, p < 0.001), especially in those with a higher socioeconomic status (p = 0.04). Finally, resilience partially mediated the association between rumination and sleep quality, with a direct association remaining. These correlational results refine understanding of their interplay and highlight rumination reduction and resilience enhancement as promising targets to be tested in longitudinal and experimental research.
