ABSTRACT
Subjective vitality is a reflection of the psychological energy and well-being of students. The purpose of this study was to investigate the relationship between disruptions to circadian rhythms and individual characteristics in predicting subjective vitality among college students. This study examined circadian rhythm disturbance and individual characteristics such gender, age, academic major, GPA, health condition, and residency as predictors of subjective vitality in university students. A survey was done using validated instruments, specifically the Subjective Vitality Scale (α = 0.87) and the SBRDA for circadian rhythm disturbance (α = 0.95). The study focused on 547 university students and was conducted in a cross-sectional manner. Both predictors and indirect effects were put through their paces using mediation models and multiple regression analyses. A total of 4.7% of the variance in subjective vitality was explained by the model, as indicated by the results (R² = 0.047, p < .001). Gender (β = 0.111, p = .005), health status (β = 0.101, p = .009), and habitation type (β = -0.120, p = .023) were found to be significant predictors in accordance with the statistical analysis. However, specialization and grade point average exhibited strong relationships with circadian disruption as a mediator. The mediation analysis revealed that there were no significant indirect effects that occurred as a result of the disruption of the circadian rhythm. Subjective vitality can be directly predicted by gender, health status, and living situations, Gender, health status, and living arrangements directly predict subjective vitality. Interventions addressing circadian regulation and health could enhance student vitality and academic outcomes.
