摘要
目的编制"青少年手机使用依赖自评问卷",评价初步在大学生中进行调查时的信度和结构效度,为进一步研究青少年手机使用依赖行为提供有效工具。方法在文献综述基础上,确定戒断症状、渴求性和身心效应3个维度,拟定16个项目;采取分层随机抽样方法,抽取合肥市某医科大学一~三年级学生2 376名进行调查。结合两独立样本t检验、Pearson相关系数法、因子分析等多种统计学方法对问卷的项目进行筛选,应用验证性因子分析评价问卷的结构效度。结果 "青少年手机使用依赖自评问卷"符合3个维度组成,共13个项目,方差累积贡献率为59.13%;总问卷的Cronbach'sα系数为0.87,各维度的Cronbach'sα系数在0.58~0.83之间;相关性分析显示,各项目与总分的Pearson相关系数均在0.3以上,与所属维度的Pearson相关系数均在0.4以上,具有较好的信、效度。验证性因子分析结果显示,问卷的近似均方根残差(RMSEA)为0.067,规范拟合指数(NFI)、相对拟合指数(RFI)、比较拟合指数(CFI)、拟合优度指数(GFI)、调整拟合优度指数(AGFI)均在0.9以上,具有较好的拟合优度。结论 "青少年手机使用依赖自评问卷"符合心理统计学评价标准,可以用来评价大学生手机使用依赖症状。
Objective To develop the Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use ( SQAPM- PU}, as well as to evaluate its reliability and construct validity in undergraduates. Methods According to literature review, the questionnaire includes sixteen items which covered three dimensions, named withdrawal symptoms, effect of physical and mental health, craving. A total of 2 376 students comprised of freshman, sophomore and junior were recruited from a university in Hefei by stratified random sampling were selected. Two-independent samples t test, Pearson correlation coefficient analysis, factor analysis and other statistical methods were used to screen the items. Confirmatory factor analysis was applied to assess the construct validity of questionnaire. Results On the basis of item analysis, the SQAPMPU was suitable for the division of three dimensions,thirteen items in total. Variance cumulative contribution rate was 59.13% ; internal consistency test showed that the total questionnaire Cronbach" sct was 0.87, Cronbach" s c~ of each dimension was between 0.58 and 0.83 ; correlation analysis explained that Pearson correlation coefficients of each item and the total score were all above 0.3, and the Pearson correlation coefficient of each item and its dimension were more than O. 4, all the indicators were at the significant level and have a great reliability and validity. Confirma- tory factor analysis results showed that the value of RMSEA was 0. 067, and the value of NFI, RFI, CFI, GFI, AGFI were above O. 9, with good fitting degree. Conclusion The SQAPMPU is consistent with the evaluation standard of psychometrics, and can be used to estimate the dependence symptoms of mobile phone use in undergraduates.
