To assess the validity and reliability of a survey designed to identify parental vaccination reluctance was the purpose of this study. A cross-sectional survey of parents of children aged 19–35 months was carried out in Changxing County, Zhejiang Province, using a questionnaire designed for the study of vaccination reluctance. Parental responses were linked to their child’s vaccination record to examine construct validity. The relationship between the mean percent of days of under-immunization, parental socio-demographic, and individual item answers was investigated using univariate and multivariate analysis. Cronbach’s alpha was used to assess the internal consistency reliability of sub-domain scales and factor analysis was used to corroborate survey sub-domains. The study sought 336 families, and 285 consented to take part in our survey. The parental ‘score of vaccine reluctance’ and education level were both substantially related to the mean percent of days of under-immunization. Cronbach’s coefficients were 0.71, 0.83, and 0.72 for the three sub-domain scales produced by re-grouping the questionnaire’s questions, respectively.
The survey was a viable and reliable tool for identifying VHPs, and it may be used to screen parents for an intervention targeted at boosting vaccine acceptability.
