Examining the Association Between Boredom Proneness and Bedtime Procrastination Among Chinese College Students: A Sequential Mediation Model with Mobile Phone Addiction and Negative Emotions

Purpose: The phenomenon of bedtime procrastination has become very common in China in recent years, especially among college students, and it can have numerous negative implications for both physical and mental health. However, the impacting factors and possible underlying mechanisms of bedtime procrastination have not yet been fully clarified. The present study aims to explore the relationship between boredom proneness and bedtime procrastination in Chinese college students, and propose a multiple mediation model to further explore the mediating effects of mobile phone addiction and negative emotions in this link. Participants and Methods: A cross-sectional study was conducted involving 668 Chinese college students aged 18 to 32 years old (M=20.36 years [SD=1.69]; 35.03% male). A series of self-rating questionnaires measuring degrees of boredom proneness, mobile phone addiction, bedtime procrastination, as well as negative emotions (depression, anxiety and stress) were administered. Results: The results showed that boredom proneness, mobile phone addiction, negative emotions and bedtime procrastination were significantly and positively correlated with each other in college students. Mobile phone addiction and negative emotions separately played partial mediating roles in the relationship between boredom proneness and bedtime procrastination. Furthermore, a sequential mediation pathway was significant whereby boredom proneness predicted mobile phone addiction, which was associated with higher levels of negative emotions, which were then associated with more bedtime procrastination behaviors. Conclusion: The present findings indicate that both mobile phone addiction and negative emotions are important risk-enhancing mediators in the association between boredom proneness and bedtime procrastination in Chinese college students. Therefore, intervention management that concentrating on reducing mobile phone addiction as well as improving negative emotions may be useful for decreasing bedtime procrastination among college students.
