Abstract:
Objective:To revise the 5C Psychological Antecedents of Vaccination Scale(5C Scale),and to examine its validity and reliability.Methods:The Chinese version of the adapted scale was formed using the Chi-nese-English back-translation method,along with expert evaluation and interview results.A questionnaire survey was administered to 1 035 residents.The effective recovery results were randomly divided into 2 groups and tested for exploratory and confirmatory factor analysis.After 2 weeks,230 residents were re-tested.The neuroticism sub-scale of the Chinese Big Five Personality Inventory Brief Version(CBF-PI-B)was used to test the criterion-related validity.Results:The 5C Scale was revised to add a new dimension of confusion,forming the 6C Psychological An-tecedents of Vaccination Scale(6C Scale)with 18 items,6 factors including confidence,complacency,constraint,calculation,collective responsibility and confusion,which accumulatively explained 67.92％of the total vari-ance.And the six-factor structural model fits well(x2/df=1.72,RMSEA=0.04,CFI=0.97,TLI=0.96,NFI=0.92,IFI=0.97).The total scores of the confusion dimension exhibited a positive association with the total scores of CBF-PI-B neuroticism subscale(ICC=0.54,P＜0.001).The Cronbach α coefficients of the 6 factors ranged from 0.68 to 0.77,and the retest reliabilities(ICC)ranged from 0.51 to 0.82.Conclusion:The 6C Psychological Antecedents of Vaccination Scale(6C Scale)revised in this study exhibits good validity and reliability in assessing residents'psychological antecedents related to vaccination.
