孤独感量表在中学生群体中的初步修订

Psychometric Evaluation of Loneliness Scale in Chinese Middle School Students

目的:对Asher的孤独感量表在中学生群体中进行修订。方法:以整群抽样法选取北京、西安的1826名中学生,对孤独感量表进行项目分析、效度分析和信度分析。结果:21个项目均具有良好的区分度,各项目与总分的相关在0.51-0.76之间。探索性因素分析提取了4个因子,符合原量表的4维度结构;验证性因素分析显示模型拟合良好;4维度及总分与效标的各维度相关显著。信度分析表明,4维度的内部一致性信度系数在0.76-0.85之间,分半信度在0.71-0.85之间,重测信度在0.71-0.88之间。结论:修订的儿童孤独感量表具有良好的信效度,可以作为中学生孤独感的测量工具。

Objective： To revise Asher＇s Child Loneliness Scale among Chinese middle school students. Methods： The study investigated 1826 middle school students by cluster sampling method. To test the reliability and validity of Children＇ s Loneliness Scale, item analysis, exploratory factor analysis, confirmatory factor analysis, criterion related validity analysis and reliability analysis were conducted. Results： 21 items in the scale had good discrimination, and the correlations be- tween items and total scores ranged from 0.51 to 0.76. Four factors were extracted by EFA, which was consistent with the original scale; Confirmatory factor analysis indicated the goodness-of-fit of model was good and the revised loneliness scale had good construct validity. There were significant correlations between four loneliness dimensions and criterion variables. Reliability analysis showed that Cronbach＇ a coefficients of the four dimensions ranged from 0.76 to 0.85, split-half reliability coefficients ranged from 0.71to 0.85, and test-retest reliability coefficients ranged from 0.71-0.88. Conclusion： The validity and reliability of the revised scale is satisfactory, which can be used in the measurement of Chinese middle school students＇ loneliness.
