The steep rise of smartphone use has raised public concerns about smartphone addiction and its associated negative health consequences, such as poor sleep quality; however, limited research has examined the psychological mechanisms underlying these associations. The current study tested the effects of smartphone addiction on poor sleep quality, through self-regulation and bedtime procrastination, among 427 Chinese undergraduate students, aged 18 or older (M = 19.36; female = 66%), who voluntarily completed an anonymous online questionnaire. The results showed that 1/3 of participants reported poor subjective sleep quality. Smartphone addiction and bedtime procrastination had a significant positive relationship, whereas self-regulation had a significant negative association, with poor sleep quality (which was assessed by sleep latency, sleep duration, and subjective sleep quality). Despite its nonsignificant direct effects, the indirect effects of smartphone addiction, via both self-regulation and bedtime procrastination, on the three indicators of poor sleep quality were statistically significant. The findings have supported the premise that both bedtime procrastination and poor self-regulation are risk-enhancing mediators on the association between smartphone addiction on poor sleep quality. Therefore, they should be considered in intervention programs (e.g., self-regulation skill training) to reduce smartphone addiction and improve sleep quality and physical wellbeing among university students.
智能手机使用的急剧增加引发了公众对智能手机成瘾及其相关负面健康后果（如睡眠质量差）的担忧；然而，针对这些关联背后心理机制的研究有限。本研究在427名18岁及以上的中国本科生（平均年龄M = 19.36岁；女生占66%）中，通过自我调节和睡前拖延，测试了智能手机成瘾对睡眠质量差的影响，这些学生自愿完成了一份匿名在线问卷。结果显示，三分之一的参与者报告主观睡眠质量差。智能手机成瘾与睡前拖延呈显著正相关，而自我调节与睡眠质量差（通过入睡潜伏期、睡眠时间和主观睡眠质量评估）呈显著负相关。尽管智能手机成瘾的直接影响不显著，但其通过自我调节和睡前拖延对睡眠质量差的三个指标产生的间接影响在统计学上是显著的。研究结果支持了这样一个前提，即睡前拖延和自我调节能力差都是智能手机成瘾与睡眠质量差之间关联的风险增强中介因素。因此，在干预项目（如自我调节技能培训）中应考虑这些因素，以减少智能手机成瘾，提高大学生的睡眠质量和身体健康水平。
