青少年在线学习心智游移问卷的编制及信效度检验

Development and reliability and validity testing of mind wandering questionnaire for adolescent online learning

目的编制青少年在线学习心智游移问卷,并对其信效度进行分析检验。方法通过文献分析和半结构式访谈编制青少年在线学习心智游移问卷。运用初始问卷(57个项目)对初测被试施测,回收有效问卷194份。初始问卷数据经分析处理后形成正式问卷(3个维度,40个项目),并对正式被试施测,回收有效问卷433份。对问卷进行项目分析和因子分析,并检验信度和效度。结果青少年在线学习心智游移问卷的内部一致性Cronbach’sα系数为0.975,分半信度为0.922,KMO值为0.948,具有良好的信度和效度;χ^(2)/df=3.191,RMSEA=0.071,IFI、CFI、TLI均在0.8以上,三维模型具有良好的拟合度;问卷与效标中文版心智游移问卷和正念注意觉知量表显著相关(r=0.764,P=0.000;r=0.724,P=0.000)。结论青少年在线学习心智游移问卷具有良好的模型结构及信效度指标,可作为青少年在线学习心智游移情况的测量工具。

Objective To develop the mind wandering questionnaire for adolescent online learning,and analyze and test the reliability and validity of the questionnaire.Methods Through literature analysis and semi-structured interviews,the mind wandering questionnaire for adolescent online learning was developed.The initial subjects were tested by using the initial questionnaire(57 items),and 194 valid questionnaires were collected.The data of the initial questionnaire was analyzed and processed to form a formal questionnaire(with 3 dimensions and 40 items).The formal subjects were tested by using the formal questionnaire,and 433 valid questionnaires were collected.Item analysis and factor analysis on the questionnaire were conducted,and reliability and validity were tested.Results The internal consistency Cronbach’sαcoefficient of the questionnaire was 0.975,the split-half reliability was 0.922,and the KMO value was 0.948,which had good reliability and validity.χ^(2)/df=3.191,RMSEA=0.071,and IFI,CFI,and TLI were all above 0.8.The threedimensional model had a good fit.Its correlations with the Chinese version of mind wandering questionnaire(r=0.764,P=0.000)and mindful attention awareness scale(r=0.724,P=0.000)were significant.Conclusion The mind wandering questionnaire for adolescent online learning has a good model structure and good reliability indicators.It can be used as a measurement tool for mind wandering of adolescent online learning.
