ABSTRACT

In the current era emphasizing health and lifestyle management, sleep health constitutes a critically important component. This study aimed to examine the mediating role of mobile phone addiction in the relationship between childhood trauma and sleep procrastination among college students. A sample of 746 college students was recruited to complete the Childhood Trauma Questionnaire (CTQ-SF), the Smartphone Addiction Scale (SAS-SV), and the Sleep Procrastination Scale. Significant positive correlations were found among childhood trauma, mobile phone addiction, and sleep procrastination. Childhood trauma positively predicted mobile phone addiction (b = 0.199, t = 5.465, p < 0.001), and mobile phone addiction positively predicted sleep procrastination (b = 0.442, t = 13.343, p < 0.001). Additionally, mobile phone addiction significantly mediated the relationship between childhood trauma and sleep procrastination, with a mediation effect size of 46.56%. These findings indicate that childhood trauma can directly contribute to sleep procrastination behaviors and can also indirectly promote sleep procrastination by influencing mobile phone addiction behaviors.
