The correlation between depressive symptoms and internet addiction in adolescents is strengthened, and childhood trauma is an important predictor of internet addiction. However, the mechanism of childhood trauma on internet addiction in adolescents with depression remains unclear. This study investigates the current status and factors influencing internet addiction in adolescents with depression and further examines whether insomnia and alexithymia mediate childhood trauma and internet addiction in adolescents with depression.
This study investigated 300 adolescent patients in 7 hospitals in Anhui province. General demographic characteristics such as age and gender were collected. The clinical characteristics of the patients were measured using the Childhood Trauma Questionnaire Short Form (CTQ-SF), Internet Addiction Test (IAT), Insomnia Severity Index (ISI) and 20-item Toronto Alexithymia Scale (TAS-20). PROCESS (Model 4) was used to examine the mediating effects of insomnia and alexithymia.
The prevalence of internet addiction among adolescents with depression was 50.2%. There were statistically significant differences between the internet addiction group and the non-internet addiction group in terms of relationships with classmates, relationships with teachers, family relations, and economic status. The total score of CTQ and its five subscale scores were significantly and positively correlated with the total score of IAT. Insomnia and externally oriented thinking (EOT) played a significant mediating role in the effect of physical neglect (PN) on internet addiction.
Insomnia and alexithymia play a significant mediating role between childhood trauma and internet addiction in adolescents with depression, which expand the existing understanding of internet addiction in adolescents with depression, and provide some theoretical references to address the problem of internet addiction in adolescents with depression and prevent the development of adolescent depression.
青少年抑郁症状与网络成瘾之间的相关性增强，童年创伤是网络成瘾的重要预测因素。然而，童年创伤对青少年抑郁症患者网络成瘾的作用机制尚不清楚。本研究调查青少年抑郁症患者网络成瘾的现状及影响因素，并进一步探讨失眠和述情障碍是否在童年创伤与青少年抑郁症患者网络成瘾之间起中介作用。
本研究对安徽省7家医院的300名青少年患者进行了调查。收集了年龄、性别等一般人口学特征。使用儿童创伤问卷简表（CTQ-SF）、网络成瘾测试（IAT）、失眠严重程度指数（ISI）和多伦多述情障碍量表20项版（TAS-20）对患者的临床特征进行测量。采用PROCESS（模型4）检验失眠和述情障碍的中介作用。
青少年抑郁症患者网络成瘾的患病率为50.2%。网络成瘾组与非网络成瘾组在同学关系、师生关系、家庭关系和经济状况方面存在统计学显著差异。CTQ总分及其五个分量表得分与IAT总分呈显著正相关。失眠和外向性思维（EOT）在身体忽视（PN）对网络成瘾的影响中起显著中介作用。
失眠和述情障碍在青少年抑郁症患者童年创伤与网络成瘾之间起显著中介作用，这拓展了对青少年抑郁症患者网络成瘾的现有认识，并为解决青少年抑郁症患者网络成瘾问题及预防青少年抑郁症的发展提供了一些理论参考。
