Comparative Analysis of the Parent Attitudes about Childhood Vaccines (PACV) Short Scale and the Five Categories of Vaccine Acceptance Identified by Gust et al. 公开

Abstract

Background: There is a need to develop a standardized tool to aid in identifying, measuring and classifying the unique needs of vaccine hesitant parents. This will also assist in designing tailored interventions to address these needs. The Parental Attitude about Childhood Vaccines (PACV) short scale developed by Opel et al., and the five categories of vaccine acceptance identified by Gust et al. have been acknowledged as potentially useful tools to measure parental vaccine hesitancy. PACV short scale requires further validation in heterogeneous populations and other geographical locations. Moreover, we need to evaluate how Gust et al. vaccine acceptance categories correspond with PACV short scale.

Objective: To analyze the PACV short scale and the Gust et al. vaccine acceptance categories to assess the ability of the PACV short scale in identifying, measuring and classifying vaccine hesitant parents.

Results / Findings: The PACV short scale and Gust et al. vaccine acceptance categories were positively correlated (r = 0.6, df = 198, p < 0.05), and the Cochran-Mantel-Haentszel test of association yielded a statistically significant association (p < 0.05). The two scales similarly predicted children's up-to-date immunization status for all recommended childhood vaccines.

Methods: As part of a larger study on vaccine attitudes, using PACV short scale and Gust et al. vaccine acceptance categories, we assessed the correlation between the two measures using Spearman correlation coefficient, and the association between the two measures, using the Cochran-Mantel-Haentszel test of association. We used logistic regression modelling to compare the association between a child's up-to-date immunization status and (a) PACV short scale and (b) Gust et al. vaccine acceptance categories.

Conclusion: The ability of the PACV short scale to identify and classify parental vaccine hesitancy is similar to classification using Gust et al. vaccine acceptance categories, and both measure linear entities. We recommend using PACV short scale to screen parents at their first pediatric visit. PACV short scale is easier to administer and measures vaccine hesitancy similarly to Gust et al. vaccine acceptance categories. A clearer understanding of how to classify parental vaccine hesitance can be used to design tailored interventions based on these classifications, to address the specific needs of these vaccine hesitant parents.
