Objective: To revise the SC 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 Chinese-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 subscale of the Chinese Big Five Personality Inventory Brief Version (CBF-PI-B) was used to test the criterion-related validity. Results: The SC Scale was revised to add a new dimension of confusion, forming the 6C Psychological Antecedents 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 variance. And the six-factor structural model fits well (X/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.

目的:对疫苗接种心理前因5C量表(5C Scale)进行修订,并检验其效度和信度。方法:采用中英文回译法和专家评定并结合访谈结果,形成改编版量表的中文版,对1 035名居民进行问卷调查,将其随机分成两组分别进行探索性和验证性因子分析;对其中230人进行间隔2周的重测。用中国大五人格问卷简式版(CBF-PI-B)的神经质分量表检验效标关联效度。结果:5C Scale修订后加入新的困惑维度,形成18个条目的疫苗接种心理前因6C量表(6C Scale),包含信任、自满、限制、计算、集体责任、困惑6个因子,累计方差解释率为67.92%;6因子结构模型拟合良好(χ~2/df=1.72,RMSEA=0.04,CFI=0.97,TLI=0.96,NFI=0.92,IFI=0.97);困惑维度总分与CBF-PI-B神经质分量表总分呈正相关(ICC=0.54,P<0.001)。6个维度的Cronbachα系数为0.68～0.77,重测信度(ICC)为0.51～0.82。结论:本研究修订形成的疫苗接种心理前因6C量表(6C Scale)评估居民的疫苗接种心理前因具有良好的效度和信度。
