手机依赖指数中文版在大学生中的信效度检验

Reliability and Validity of Mobile Phone Addiction Index for Chinese College Students

目的:检验手机依赖指数(Mobile phone addiction index,MPAI)在中国大学生人群中应用的信度和效度。方法:用MPAI中文版对1392名大学生施测。在所有样本中抽取50人间隔五周后实施重测。同时测查了症状自评量表(SCL-90)和总体幸福感量表(GWB),进行效标效度的验证。结果:验证性因子分析结果支持模型2的一阶四因子结构,各拟合指标分别为χ2/df=8.85,RMSEA=0.075,NFI=0.97,IFI=0.97,CFI=0.97,GFI=0.92。MPAI中文版所有项目的决断值均显著(P<0.001),项目与量表总分的相关在0.57~0.71之间。总量表及失控性、戒断性、逃避性和低效性的Cronbach’sα系数依次为0.91、0.84、0.83、0.87和0.81,5周后重测信度依次为0.69、0.61、0.70、0.69和0.60。MPAI中文版总分及四因子得分与SCL-90总分及各因子得分呈显著性正相关(r=0.27~0.54,P<0.001),与总体幸福感总分呈显著性负相关(r=-0.38^-0.49,P<0.001)。结论:手机依赖指数中文版具有较好的信效度,可以作为我国大学生手机依赖研究的工具。

Objective： To test the reliability and validity of the Chinese version of Mobile phone addiction index（MPAI）.Methods： A sample of 1392 college students was tested, in which 50 students were selected for re-test five weeks later.Meanwhile, The Symptom Checklist-90（SCL-90） and General Well-Being Scale（GWB） were selected as the criterion measurement. Results： The results of confirmatory factor analysis support the first-order four- factor structure of model 2, the fit in dices were χ^2/df=8.85, RMSEA=0.075, NFI=0.97, IFI=0.97, CFI=0.97, GFI=0.92, all meeting the criteria standards for adequacy of fit. The critical ratios of all the items in Chinese version of MPAI were significantly（P〈0.001）, the correlation between each item and the total score ranged from 0.57 to 0.71. The Cronbach＇s α coefficients of the total scale, inability to control carving subscale, the feeling anxious and lost subscale, the withdrawal subscale and the productivity loss subscale respectively were 0.91, 0.84, 0.83, 0.87 and 0.81, and the test-retest reliability after 5 weeks were 0.69, 0.61, 0.70, 0.69 and 0.60 respectively. The total score and four factors of the Chinese version of MPAI showed a significantly positive correlation with that of the SCL-90 score（r=0.27-0.54, P〈0.001）, and significantly negative correlated with the score on the General Well- being Scale（r=-0.38--0.49, P〈0.001）. Conclusion： The Chinese version of Mobile phone addiction index has good reliability and validity, which can be used as a useful tool to research mobile phone addiction in Chinese college students.
