目的对初步编制的“中学生生活技能评价量表”进行信度和效度检验,为国内生活技能教育提供有效的测评工具。方法在北京、内蒙古、新疆、陕西、上海5个省(市),采用方便整群抽样方法抽取20所初中学校与20所高中学校共4 990名学生进行“中学生生活技能评价量表”的问卷调查。结果全量表Cronbach’sα内部一致性信度系数为0.946,分量表的信度系数分别为0.626～0.844;分半信度的Spearman相关系数为0.814(P<0.01);各因子与总量表得分之间的相关系数为0.619～0.865(P值均<0.01);采用主成分分析法,验证性的提取8个公因子,累计可以解释总体变异的54.47%;量表的区分效度较好(P<0.01)。结论初步编制的“中学生生活技能评价量表”具有良好的信度和效度。个别题目经修订和再次验证后,可以作为国内生活技能教育的测评工具。
Objective To test the reliability and validity of the “Secondary School Students’ Life Skills Evaluation Scale” compiled initially, and provide an effective evaluation tool for domestic life skills education. Methods A total of 4 990 students from 20 middle schools and 20 high schools were recruited by cluster sampling method in Beijing, Inner Mongolia, Xinjiang, Shaanxi and Shanghai to carry out a questionnaire on “Life Skills Assessment for Secondary School Students” Questionnaire. Results The internal consistency reliability coefficient of Cronbach’sα was 0.946, the reliability coefficients of subscale were 0.626-0.844, Spearman’s correlation coefficient was 0.814 (P <0.01); the factors and total scale score (P <0.01). The Principal Component Analysis (PCA) was used to validate the extraction of eight common factors, which could explain 54.47% of the total variation, and the discriminant validity of the scale was good P <0.01). Conclusion The preliminarily compiled “Students’ Life Skills Assessment Scale” has good reliability and validity. After individual items are revised and re-verified, they can be used as assessment tools for domestic life skills education.
