中文版青少年社会资本问卷信效度分析

Reliability and Validity of the Chinese Version of Social Capital Questionnaire for Adolescent Students

目的翻译青少年社会资本问卷(SCQ-AS),对中文版SCQ-AS进行信效度分析,验证其在中国学生中的适用情况,为研究青少年学生社会资本提供测量工具。方法于2016年4—5月,采用便利抽样方法,选取辽宁省彰武县12个班级学生350例为研究对象。由4名护理学专业的老师和学生对问卷进行翻译,再由2名非医学领域的小学和初中英语教师提出改进意见,根据预调查结果进一步修改完善,最终得到中国文化背景下的中文版SCQ-AS。采用匿名的方式进行正式问卷调查,选择60例调查对象于2周后进行重测。结果本研究获得有效问卷334份,有效回收率为95.4%。问卷整体Cronbach'sα系数为0.829,分半信度系数为0.692,重测信度系数为0.710(P<0.001)。SCQ-AS各条目得分与总分均呈正相关,r值为0.458~0.715(P<0.05)。由5名护理学专家对SCQ-AS条目进行评分,内容效度指数为0.816。探索性因子分析提取到特征值>1.000的公因子4个,累积方差贡献率为66.369%。公因子1在条目5~7、10上有较大载荷,公因子2在条目1~4上有较大载荷,公因子3在条目8、9上有较大载荷,公因子4在条目10~12上有较大载荷。验证性因子分析显示,χ~2/df=1.874,拟合优度指数(GFI)=0.922,比较拟合指数(CFI)=0.937,Tucker-Lewis系数(TLI)=0.914,增殖拟合指数(IFI)=0.939,近似误差均方根(RMSEA)=0.071,调整的拟合优度指数(AGFI)=0.874,规范拟合指数(NFI)=0.878,结构模型拟合良好。结论中文版SCQ-AS具有良好的信效度,可作为针对我国青少年学生社会资本的调查工具。

Objective To examine the reliability and validity of the translated Chinese version of Social Capital Questionnaire for Adolescent Students（SCQ-AS）,and to verify its application in Chinese adolescent students so as to provide a measurement tool for the study of social education for young students.Methods From April to May 2016,we selected 350 students from Zhangwu County,Liaoning Province as the subjects of this study by using convenient sampling method.The finished Chinese version of SCQ-AS under Chinese cultural context used in this study was finally developed after 2 revisions and improvements of the original Chinese version of SCQ-AS translated by 4 teachers and students of nursing,the first revision and improvement was based upon the suggestions of 2 primary and junior high school English teachers with no medical background,and the second was based on the pre-survey results.With the Chinese version of SCQ-AS,we conducted a formal anonymous survey in the subjects,and a second survey in 60 of whom two weeks later.Results A total of 334 valid questionnaires were obtained,with a response rate of 95.4%.The results of the surveys showed that the Cronbach′s α,split-half reliability coefficient,and retest reliability coefficient of the questionnaire was 0.829,0.692 and 0.710,respectively（P〈0.001）.The scores of each item in the Chinese version of SCQ-AS were positively correlated with the total score,r values ranged from 0.458 to 0.715（P〈0.05）.The Chinese version of SCQ-AS was assessed by 5 nursing experts,and the content validity index was 0.816.Four common factors with eigenvalues 〉1.000 were extracted by exploratory factor analysis with a cumulative variance contribution rate of 66.369%.Common factor 1 had greater loads on items from 5 to 7,and item 10,while common factor 2 had those on items from 1 to 4,common factor 3 had those on items 8 and 9,and common factor 4 had those on items from 10 to 12.Confirmatory factor analysis showed that x2/df=1.874,GFI=0.922,CFI=0.937,TLI=0.914,IFI=0.939, RMSEA=0.071,AGFI=0.874,NFI=0.878,which indicated that the fitness of theoretical structure of Chinese version of SCQ-AS was good.Conclusion Chinese version of SCQ-AS has good reliability and validity,which can be used as a tool for the investigation of social capital of young students in China.
