目的了解网络活动与青少年问题性网络使用的关系,为引导青少年正确使用网络及减少问题性网络活动带来的不利影响提供参考。方法采用自评问卷,对来自中国科学院心理研究所双生子研究样本库1 378对青少年双生子的网络活动进行第一轮调查,1.5 a后对样本进行追踪,从中随机抽取1 650名被试测量其发生问题性网络使用的情况。结果个体上网时间与问题性网络使用呈正相关,且青少年周末上网时间能显著预测后期问题性网络使用的得分。第一轮测试参与娱乐和社交活动的种类越多,第二轮测试中问题性网络使用得分就越高(r娱乐=0.192,r社交=0.182,P值均<0.01);而参与信息活动的种类与问题性网络使用没有相关性(r=0.008,P=0.748)。高娱乐高社交组和高娱乐低社交组青少年问题性网络使用的得分高于高社交低娱乐组和低娱乐低社交组的得分(P值均<0.05)。结论青少年周末上网时间能预测问题性网络使用的发生;较之单一的网络活动,娱乐和社交的共同作用与问题性网络使用有更密切的关系。
Objective To understand the relationship between internet activities and the use of problematic internet for adolescents and to provide reference for guiding young people to use the internet properly and reduce the adverse effects of the problematic internet activities. Methods A self-assessment questionnaire was used to investigate the internet activities of twins in adolescent twins from 1 378 samples from the Institute of Psychology, Institute of Psychology, Chinese Academy of Sciences. After 1.5 years, the samples were traced, and randomly selected 1 650 test samples It occurs when the problem network is in use. Results The individual online time was positively correlated with the use of problematic internet, and the weekend online time of young people could significantly predict the scores of late-stage internet use. The more types of entertainment and social activities were involved in the first round of testing, the higher the scores of problematic internet use in the second round of tests (r = 0.192, r = 0.182, P <0.01) There was no correlation between category and questionable internet use (r = 0.008, P = 0.748). The score of Internet use problem of adolescent with high entertainment high social group and high entertainment low social group was higher than that of high social low entertainment group and low entertainment low social group (P <0.05). Conclusions Adolescents’ time spent surfing the Internet on weekends can predict the occurrence of problematic internet use; the combined effect of entertainment and sociality is more closely linked to problematic internet use than single-network activity.
