信息安全态度量表的汉化及信效度检验

Reliability and validity of the Chinese version of the Information Security Attitude Questionnaire

目的汉化信息安全态度量表(Information Security Attitude Questionnaire,ISA-Q)并检验其信效度。方法使用Beaton跨文化调适指南对ISA-Q进行汉化,通过翻译、整合、回译、专家委员会审核、跨文化调适以及预调查形成中文版ISA-Q,对4所三甲医院959名护士进行问卷调查,以评价量表的信效度。结果探索性因子分析提取特征值>1的6个公因子(环境控制、维护设备稳定、信息访问限制、工作系统性、提升职业责任感和持续教育培训),累计方差贡献率为64.222%;验证性因子分析显示,χ^(2)/df=1.219,RMSEA=0.022,AGFI=0.921,GFI=0.934,NFI=0.939,CFI=0.988,TLI=0.987。量表条目水平的内容效度指数为0.846~1.000,量表水平的内容效度指数为0.986。量表的Cronbach′sα系数0.870,重测信度0.884,折半信度0.781。结论中文版ISA-Q信效度良好,可作为我国护士信息安全态度的评估工具。

Objective To translate the Information Security Attitude Questionnaire(ISA-Q)into simplified Chinese,and to assess its reliability and validity.Methods Following Beaton′s guidelines for the process of cross-cultural adaptation of self-report mea-sures,the Chinese version of the ISA-Q was developed through translation,synthesis,back-translation,expert committee review,cross-cultural adaptation,and a pilot survey.A questionnaire survey was conducted among 959 nurses from 4 tertiary hospitals to evaluate the reliability and validity of the questionnaire.Results Exploratory factor analysis identified six factors with eigenvalue of more than 1,which could explain 64.222%of the total variance.These factors were named as:environmental control,maintaining facility stability,restricting access to information,work systematicity,promoting professional responsibility,and continuous education.Confirmatory factor analysis showed that the 30-item six-factor structure of the questionnaire fitted well to the dataset(χ^(2)/df=1.219,RMSEA=0.022,AGFI=0.921,GFI=0.934,NFI=0.939,CFI=0.988,TLI=0.987).The item-level content validity index ranged from 0.846 to 1.000,and the scale-level content validity index was 0.986.The Cronbach′s alpha coefficient was 0.870,the test-retest reliability was 0.884,and the split-half reliability was 0.781.Conclusion The Chinese version of the ISA-Q demonstrates good reliability and validity,and can be used to assess the attitudes of Chinese nurses toward information security.
