OBJECTIVE: This study aims to explore the mechanisms by which maladaptive perfectionism influences bedtime procrastination in college students and to analyze the chain-mediating roles of nomophobia and physical exercise.
METHODS: Questionnaires were administered to 486 university students using the Multidimensional Perfectionism Scale, Bedtime Procrastination Behaviour Scale, Nomophobia Scale and Physical Exercise Rating Scale.
RESULTS: The bias-corrected nonparametric percentile Bootstrap method was used to test the mediating effect. The direct effect of maladaptive perfectionism on college students' bedtime procrastination is significant (effect = 0.126). Nomophobia significantly mediated the relationship (effect = 0.409), as did physical exercise (effect = 0.032). The chained mediation effect of nomophobia and physical exercise was significant (effect = 0.033), and all the above path Bootstrap 95 % confidence intervals excluded zero, indicating statistical significance.
CONCLUSION: Maladaptive perfectionism influences bedtime procrastination directly and indirectly via nomophobia and physical exercise, including a chain-mediated pathway. This provides theoretical reference for understanding the causation of bedtime procrastination in college students, and also expands the prevention and intervention of bedtime procrastination behaviours.
