The impact of negative events on adolescent sleep quality: the role of negative attention bias and negative emotions

Background: Sleep is a critical factor affecting college students' physical and mental health, closely intertwined with their daily lives and academic performance. While previous studies have examined the relationship between negative life events and sleep quality among college students, few have explored the mediating role of negative attentional bias and negative emotions in this relationship. Based on cognitive-behavioral theory, this study investigates the impact of negative life events on college students' sleep quality and examines the mediating roles of negative attentional bias and anxiety. Methods: A total of 566 college students were assessed using the Adolescent Life Events Scale, Negative Attention Bias Scale, Depression-Anxiety-Stress Scale, and Pittsburgh Sleep Quality Index. Results: < 0.001). Conclusion: These findings contribute to understanding the mechanisms underlying sleep quality in college students and provide insights for sleep quality interventions.
