青少年戒烟动机量表的汉化及信效度检验

Reliability and validity of Chinese version of Adolescent Reasons for Quitting Scale

目的·引进并汉化青少年戒烟动机量表(Adolescent Reasons for Quitting Scale,ARFQ),检验其信效度。方法·均采用方便抽样的原则,样本1选取384名高中生进行施测,对数据进行项目分析、探索性因子、区分效度、内部一致性信度和分半信度分析;样本2选取191名高中生进行施测,对数据进行验证性因子分析;间隔4周后,在样本1中选取60名学生进行重测。结果·中文版ARFQ包括4个维度16个条目。探索性因子分析提取的4个公因子分别命名为"短期后果""长期关注""社会反对""亲友反对",累计方差贡献率达到64.04%。验证性因子分析结果提示,四因子模型拟合度良好(卡方自由度比为2.06,近似误差均方根为0.05,增量拟合指数为0.95,拟合优度指数为0.94,修正的拟合优度指数为0.91,Tucker-Lewis指数为0.94)。总量表的内部一致性Cronbach'sα系数为0.79,各维度系数为0.72~0.90。分半信度为0.76,重测信度为0.84。结论·中文版ARFQ具有良好的信效度,可以作为青少年戒烟动机的测量工具。

Objective·To introduce and localize the Adolescence Reasons for Quitting Scale(ARFQ)and test its reliability and validity.Methods·Convenient sampling was used.Three hundred and eighty-four high school students were selected as sample 1 for item analysis,exploratory factor analysis,discriminant validity test,internal consistency reliability and split-half reliability.One hundred and ninety-one high school students were selected as sample 2 for confirmatory factor analysis.Four weeks later,60 students in sample 1 were selected for retest.Results·The Chinese version of ARFQ included 4 dimensions and 16 items.Four common factors extracted by exploratory factor analysis were named"Short-Term Consequences""Long-Term Concerns""Social Disapproval"and"Relatives'and Friends'Disapproval",and the cumulative variance contribution rate was 64.04%.Confirmatory factor analysis showed that four-factor model fitted well[χ2/df=2.06,root mean square error of approximation(RMSEA)=0.05,incremental fit index(IFI)=0.95,goodness of fit index(GFI)=0.94,adjusted goodness of fit index(AGFI)=0.91,and Tucker-Lewis index(TLI)=0.94].The Cronbach'sαcoefficient of the scale was 0.79,and the coefficient of each dimension was 0.72-0.90.The split-half reliability was 0.76,and the test-retest reliability was 0.84.Conclusion·The Chinese version of ARFQ is a valid and reliable instrument to measure the motivation of adolescents'quitting smoking.
