Reliability and validity of the Chinese version of the Information Security Attitude Questionnaire
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 edu-cation.Confirmatory factor analysis showed that the 30-item six-factor structure of the questionnaire fitted well to the dataset(x2/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.
