手机依赖测验中文版在青少年中的信效度检验

Reliability and Validity of The Test of Mobile Phone Dependence for Chinese Adolescents

目的:以青少年为研究对象,对手机依赖测验(The Test of Mobile Phone Dependence,TMD)进行中文修订和信效度检验。方法:用手机测验中文版(TMD-C)对788名青少年施测,将样本随机分成两等份,分别进行探索性与验证性因素分析,抽取200人间隔4周实施重测。结果:通过因子分析获得4因子结构和3因子结构,经比较,4因子结构各项指标拟合度更优。TMD-C包含突显性、耐受性和干扰其他活动、戒断症状、失去控制4个维度共20个项目,各因子负荷在0.44~0.79,累计贡献率为54.91%。量表结构效度良好(χ^2/df=2.29,RMSEA=0.056,CFI=0.922,NFI=0.895,IFI=0.923,AGFI=0.910);总量表的Cronbach’sα系数为0.90,4个因子的系数在0.69~0.83之间;总量表重测信度为0.76,4个因子的重测信度在0.65~0.70之间;TMD-C与手机依赖指数中文版、抑郁、孤独感均呈显著正相关。结论:手机依赖测验中文版具有良好的信效度,可以作为我国青少年手机依赖研究的测评工具。

Objective:To test the reliability and validity of the Test of Mobile Phone Dependence(TMD)in adolescents.Methods:A sample of 788 adolescences were tested,the samples were randomly divided into two equal parts for explorato?ry and confirmatory factor analysis.in which 200 students were selected for re-test four weeks later with the TMD Chinese version.Results:The 4-factor structure and 3-factor structure scale were obtained by factor analysis.After comparison,the 4-factor structure scale had better fitting degree.TMD-C included 20 items with 4 dimensions,such as prominence,tol?erance and interference with other activities,abstinence symptoms and out of control.Each factor was loaded in 0.44~0.79,and the cumulative contribution rate was 54.91%.The structure validity of the scale was good(χ^2/df=2.29,RMSEA=0.056,CFI=0.922,NFI=0.895,IFI=0.923,AGFI=0.910);the Cronbach’s a coefficient of the total scale was 0.90,the coefficient of 4 factors was between the 0.69~0.83;the total scale retest reliability was 0.76,and the test-retest reliability of 4 factors was between 0.65 and 0.70;TMD-C were positively correlated with the Chinese version of mobile phone addiction index,de?pression and loneliness.Conclusion:The mobile phone dependence test Chinese version has good reliability and validity,and can be used as a tool for young people’s mobile phone dependence research in China.
