To explore the relationship between mobile phone addiction and physical exercise behavior among college students, and to analyze the mediating effect of bedtime delay between the two, to provide a basis for the development of good behavioral habits among college students.
The Mobile Phone Addiction Scale, the Physical Activity Behavior Self-Assessment Scale, and the Bedtime Procrastination Scale were administered to 356 college students (49.4% male) in Sichuan Province. Structural equation modeling was then conducted to test the mediating effects.
(1) There is no gender difference in mobile phone addiction, bedtime procrastination, and physical activity behavior among college students (all > 0.05). (2) There was a significant negative correlation between college students' mobile phone addiction and physical activity behavior ( = -0.688, < 0.01); a significant positive correlation between college students' mobile phone addiction and bedtime delay ( = 0.730, < 0.01); and a significant negative correlation between bedtime delay and physical activity behavior ( = -0.658, < 0.01). (3) Bedtime delay mediates the relationship between mobile phone addiction and physical activity behavior among college students (β = -0.27).
(1) There is a close relationship between mobile phone addiction, bedtime procrastination, and physical activity behavior among college students; (2) Mobile phone addiction significantly impacts the physical activity behavior of college students. Additionally, it indirectly influences their physical activity behavior through procrastination at bedtime.
探讨大学生手机成瘾与体育锻炼行为之间的关系，并分析就寝延迟在二者之间的中介作用，为大学生养成良好行为习惯提供依据。
对四川省356名大学生（男性占49.4%）施测手机成瘾量表、体育活动行为自评量表和就寝拖延量表。然后进行结构方程模型分析以检验中介效应。
（1）大学生在手机成瘾、就寝拖延和体育活动行为方面不存在性别差异（均P>0.05）。（2）大学生手机成瘾与体育活动行为之间存在显著负相关（r=-0.688，P<0.01）；大学生手机成瘾与就寝延迟之间存在显著正相关（r=0.730，P<0.01）；就寝延迟与体育活动行为之间存在显著负相关（r=-0.658，P<0.01）。（3）就寝延迟在大学生手机成瘾与体育活动行为之间起中介作用（β=-0.27）。
（1）大学生手机成瘾、就寝拖延和体育活动行为之间关系密切；（2）手机成瘾显著影响大学生的体育活动行为，此外，它还通过就寝拖延间接影响大学生的体育活动行为。
