The impact of maladaptive perfectionism on college students' bedtime procrastination: The chain mediating effects of nomophobia and physical exercise.

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.
