Exercise self-efficacy refers to an individual's cognitive ability to believe that they can accomplish the goals and tasks of physical activity, which is particularly important for developing physical and mental health. Therefore, this study aimed to investigate the association between mobile phone addiction, bedtime procrastination, and exercise self-efficacy among college students, and to provide intervention directions and theoretical insights for developing college students' physical and mental health.
Using the College Students' Mobile Phone Addiction Scale, the Bedtime Procrastination Scale, and the Exercise Self-Efficacy Scale, a longitudinal follow-up survey of 407 college students in provinces X and Y was conducted at 3-month intervals in May 2024 (T1) and August 2024 (T2) to analyze the mechanism of the interaction between the College Students' Mobile Phone Addiction Scale, the Bedtime Procrastination Scale and the exercise self-efficacy using cross-lagging.
There was no significant difference between mobile phone addiction, bedtime procrastination, and exercise self-efficacy among college students in terms of gender, academic year, and age. It was found that T1 mobile phone addiction positively predicted T2 bedtime procrastination (β = 0.15, p < 0.05), while T1 bedtime procrastination positively predicted T2 mobile phone addiction (β = 0.15, p < 0.001), indicating that mobile phone addiction and bedtime procrastination predicted each other temporally. In addition, T1 bedtime procrastination negatively predicted T2 exercise self-efficacy (β = -0.10, p < 0.05) and T1 mobile phone addiction negatively predicted T2 exercise self-efficacy (β = -0.12, p < 0.05).
There was a longitudinal predictive relationship between cell phone addiction, bedtime procrastination, and exercise self-efficacy; cell phone addiction and bedtime procrastination predicted each other; bedtime procrastination predicted exercise self-efficacy; and cell phone addiction predicted exercise self-efficacy.
运动自我效能是指个体相信自己能够完成体育活动目标和任务的认知能力，这对身心健康发展尤为重要。因此，本研究旨在探讨大学生手机成瘾、睡前拖延与运动自我效能之间的关联，并为促进大学生身心健康提供干预方向和理论见解。
采用大学生手机成瘾量表、睡前拖延量表和运动自我效能量表，于2024年5月（T1）和2024年8月（T2）对X省和Y省的407名大学生进行为期3个月的纵向跟踪调查，运用交叉滞后分析大学生手机成瘾量表、睡前拖延量表与运动自我效能之间的相互作用机制。
大学生在手机成瘾、睡前拖延和运动自我效能方面，在性别、学年和年龄上无显著差异。研究发现，T1手机成瘾正向预测T2睡前拖延（β = 0.15，p < 0.05），而T1睡前拖延正向预测T2手机成瘾（β = 0.15，p < 0.001），表明手机成瘾和睡前拖延在时间上相互预测。此外，T1睡前拖延负向预测T2运动自我效能（β = -0.10，p < 0.05），T1手机成瘾负向预测T2运动自我效能（β = -0.12，p < 0.05）。
手机成瘾、睡前拖延与运动自我效能之间存在纵向预测关系；手机成瘾和睡前拖延相互预测；睡前拖延预测运动自我效能；手机成瘾预测运动自我效能。
