To investigate the prevalence of Internet addiction among Chinese adolescents and to explore the psychological features associated with Internet addiction.
A total of 2620 high school students from four high schools in Changsha City were surveyed using Diagnostic Questionnaire for Internet Addiction (YDQ), Eysenck Personality Questionnaire (the edition for children, EPQ), Time Management Disposition Scale (TMDS) and Strengths and Difficulties Questionnaire (SDQ). The mean age of whole sample was 15.19 years (ranging from 12 years to 18 years). According to the modified YDQ criteria by Beard, 64 students who were diagnosed as Internet addiction (the mean age: 14.59 years) and 64 who were diagnosed as being normal in Internet usage (the mean age: 14.81 years) were included in a case-control study.
The rate of Internet use among the surveyed adolescents was 88%, among which the incidence rate of Internet addiction was 2.4%. The Internet addiction group had significantly higher scores on the EPQ subscales of neuroticism, psychoticism, and lie than the control group (P < 0.05). The Internet addiction group scored lower than the control group on the TMDS subscales of sense of control over time, sense of value of time, and sense of time efficacy (P < 0.05). Compared with the control group, the Internet addiction group had also significantly higher scores on the SDQ subscales of emotional symptoms, conduct problems, hyperactivity, total difficulties and lower scores on the subscale of prosocial behaviours (P < 0.05).
The present study suggests that Internet addiction is not rare among Chinese adolescents. In addition, adolescents with Internet addiction possess different psychological features when compared with those who use the Internet less frequently.
调查中国青少年网络成瘾的患病率，并探讨与网络成瘾相关的心理特征。
使用网络成瘾诊断问卷（YDQ）、艾森克人格问卷（儿童版，EPQ）、时间管理倾向量表（TMDS）和长处与困难问卷（SDQ），对长沙市四所高中的2620名高中生进行了调查。整个样本的平均年龄为15.19岁（年龄范围为12岁至18岁）。根据Beard修改后的YDQ标准，64名被诊断为网络成瘾的学生（平均年龄：14.59岁）和64名被诊断为网络使用正常的学生（平均年龄：14.81岁）被纳入病例对照研究。
被调查青少年的网络使用率为88%，其中网络成瘾的发生率为2.4%。网络成瘾组在EPQ神经质、精神质和说谎分量表上的得分显著高于对照组（P<0.05）。网络成瘾组在TMDS时间控制感、时间价值感和时间效能感分量表上的得分低于对照组（P<0.05）。与对照组相比，网络成瘾组在SDQ情绪症状、行为问题、多动、总困难分量表上的得分也显著更高，而在亲社会行为分量表上的得分更低（P<0.05）。
本研究表明，网络成瘾在中国青少年中并不罕见。此外，与较少使用互联网的青少年相比，网络成瘾的青少年具有不同的心理特征。
