摘　　要：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 Secondary School Students＇ Life Skills Scale which was drew up,in order to promote an effective evaluation tool for life skills in China.Methods A total of 4 990 students from 20 junior schools and 20 high schools in Beijing city,Shanghai city,Inner Mongolia,Xinjiang and Shaanxi province were sampled with convenient cluster sampling to test the reliability and validity of the scale.Results Cronbach＇s α of the total scale was 0.946,of the 8 subscales was 0.626-0.844,Split-half coefficient was 0.814,which showed the reliability of the scales was accurate;The correlated coefficients between total scale and 8 subscales were 0.619-0.865（P0.01）,the 8 factors could explain 54.47 % of total scale variances,which showed good content validity;the scale also had good discrimination structure.Conclusion Secondary School Students＇ Life Skills Scale has good reliability and validity,as a primary scale,several titles needs to be revised and further improvements,then it can be used as an evaluation tool for life skills in China.
