School bullying and Internet addiction are both common public health problems for adolescents. Several studies found an association between school bullying and Internet addiction; however, the underlying mediating and moderating mechanisms of the complex relationship between school bullying and Internet addiction are limited.
This study explored the mediating role of depression in the relationship between school bullying and Internet addiction and whether smoking moderated the relationship between school bullying and depression in Chinese southeastern adolescents.
A cross-sectional study was conducted in Guangdong Province in Southeast China in June 2021. Associations between Internet addiction, school bullying, and depression were estimated using Spearman correlation analysis, the mediation effect and moderation effect were examined using Model 4 and Model 7 in the Hayes' PROCESS macro.
The results included 1992 adolescents, 23.5% and 28.0% of participants reported experiences of school bullying and Internet addiction, respectively. There was a significant correlation between school bullying, depression, and Internet addiction ( < 0.01). School bullying direct effects on Internet addiction [ = 0.565, = 0.053, 95% (0.461, 0.669)], depression partially mediated the association between school bullying and Internet addiction, with the mediation effect size being 36.5%. And smoking played a moderating role between school bullying and depression [ = -0.166, = 0.058, 95% (-0.280, -0.052)].
In Chinese southeastern adolescents, depression mediated the relationship between school bullying and Internet addiction, and smoking moderated the relationship between school bullying and depression.
校园欺凌和网络成瘾都是青少年常见的公共卫生问题。多项研究发现校园欺凌与网络成瘾之间存在关联；然而，校园欺凌与网络成瘾之间复杂关系的潜在中介和调节机制尚不清楚。
本研究探讨抑郁在校园欺凌与网络成瘾关系中的中介作用，以及吸烟是否调节了中国东南部青少年校园欺凌与抑郁之间的关系。
2021年6月在中国东南部的广东省进行了一项横断面研究。采用Spearman相关分析估计网络成瘾、校园欺凌和抑郁之间的关联，使用Hayes的PROCESS宏中的模型4和模型7检验中介效应和调节效应。
研究对象包括1992名青少年，分别有23.5%和28.0%的参与者报告有校园欺凌和网络成瘾经历。校园欺凌、抑郁和网络成瘾之间存在显著相关性（<0.01）。校园欺凌对网络成瘾有直接影响[=0.565，=0.053，95%（0.461，0.669）]，抑郁部分中介了校园欺凌与网络成瘾之间的关联，中介效应大小为36.5%。吸烟在校园欺凌与抑郁之间起调节作用[=-0.166，=0.058，95%（-0.280，-0.052）]。
在中国东南部青少年中，抑郁中介了校园欺凌与网络成瘾之间的关系，吸烟调节了校园欺凌与抑郁之间的关系。
