健康的网络使用的概念与构成

The Concept and Construct of Healthy Internet Use

目的：从＂二维的视角＂出发,论述健康的网络使用需要独立于网络成瘾测量的原因,阐释与检验健康的网络使用的概念与构成,并探索其与网络成瘾的关系。方法：抽取555名上海某高校的大学生样本进行探索性因子分析（EFA）;并在线上线下抽取了487名非学生样本用于验证性因子分析（CFA）;最后对两组样本分别进行主要变量的相关分析。结果：EFA提取了健康的网络使用的4个维度：＂现实规划＂、＂知识获取＂、＂娱乐自控＂和＂积极结果＂;CFA的结果显示,模型建构效度良好,模型拟合度较高（χ^2=df=3.525,NFI=0.928,GFI=0.940,CFI=0.947,RMSEA=0.072）。量表的信度较好,两组样本各维度的Cronbach’sα和Spearman-Brown系数基本大于0.7。相关分析显示这4个维度与网络成瘾的关系不尽相同,Pearson系数在-0.224（P〈0.01）-0.280（P〈0.01）。结论：健康的网络使用与网络成瘾是不同但又重叠的网络使用模式。

Objective：The current study adopts a＂dual continua＂perspective and aims to explain the reasons that healthy Internet use（HIU）should be measured separately from internet addiction,elucidate the concept and construct of HIU,and explore the relations between HIU and internet addiction.Methods：Researchers sampled 555 students from a university in Shanghai to conduct EFA,and collected a sample of 487 non-student participants to conduct CFA.Based on the two samples,the current study analyzed the correlations between main variables.Results：The results of EFA showed that HIU was composed of four dimensions：＂real-life planning＂,＂knowledge seeking＂,＂entertainment self-regulating＂,and＂positive outcomes＂.The model of CFA had acceptable construct validity and good model fit（χ^2=df=3.525,NFI=0.928,GFI=0.940,CFI=0.947,RMSEA=0.072）.Most of the Cronbach＇sɑand Spearman-Brown coefficients of the HIU dimensions were above 0.7,indicating acceptable reliability.The HIU dimensions and internet addiction had dissimilar relations,with Pearson coefficients between -0.224（P〈0.01）and 0.280（P〈0.01）.Conclusion：Healthy internet use and internet addiction reflect two different but overlapped internet use models.
