大学生手机使用动机量表的初步编制

Development the Mobile Phone Usage Motivation Scale for College Students

目的：编制＂大学生手机使用动机量表＂,初步评价在大学生中的信度和效度。方法：结合已有文献和深度访谈编制问卷,对分层随机抽取中国矿业大学860名大学生进行调查,对数据进行项目分析、内部一致性分析、相关分析、探索性因子分析和验证性因子分析。结果：提取人际动机、工具动机和娱乐动机3个公因子,解释方差变异的57.089%;总量表的Cronbachα系数为0.85,各维度的Cronbachα系数在0.695~0.792之间;各项目与总分的相关系数在0.512~0.649之间,与所属维度的相关系数在0.688~0.824之间,具有较好的信效度。验证性因子分析结果显示,χ2/df=3.791,NFI=0.904,CFI=0.922,GFI=0.970,AGFI=0.945,RMSEA=0.066,各项指标拟合度良好。男、女生在人际动机和娱乐动机上的得分差异具有统计学意义;不同年级的大学生在人际动机、工具动机和娱乐动机上差异具有统计学意义;不同生源地大学生在人际动机、工具动机和娱乐动机上差异具有统计学意义（P〈0.01）。结论：大学生手机使用动机量表符合心理统计学评价标准,可以用来评价大学生的手机使用动机。

Objective： To develop the Mobile Phone Usage Motivation Scale for College Students （MPUMS -CS）, as well as to evaluate its reliability and validity. Methods：According to literature and interview, a total of 860 college students comprised of freshman, sophomore ,junior and senior were recrui- ted from China University of Mining and Technology by stratified random sampling. The exploratory factor analysis and confirmatory factor analysis were evaluated, as well as item analysis, internal consistency a- nalysis and correlation analysis. Results：Three factors were extracted including interpersonal motivation, instrumental motivation and entertainment motivation which could explain 57. 089% of variance variation. The total scale Cronbach α was 0.85, Cronbach α of each dimension was between 0. 695 and 0.792. The person correlation coefficients of each item and the total score were between 0.5 !2 and 0. 649, and the person correlation coefficients of each item and its dimension were between 0. 688 and 0.824, all the indi- cators had a great reliability and validity. Confirmatory factor analysis results showed that good fitting de- gree with x2/df = 3. 791, NFI = 0.904, CFI = 0.922, GFI = 0.970, AGFI = 0.945, RMSEA = 0. 066. Gen- der difference significantly existed in interpersonal motivation and entertainment motivation （P 〈 0.01 ）. Different grade had significant differences in interpersonal motivation, instrumental motivation and enter- tainment motivation（P 〈 0.01 ）. Different origin had significant differences in interpersonal motivation, in- strumental motivation and entertainment motivation（P 〈0. Ol ）. Conclusion：The MPUM- CS is consist- ent with evaluation standard of psychometrics, and can be used to estimate the mobile phone usage motiva- tion of college students.
