The Vaccine Attitude Scale: Psychometric Properties and Validation

Abstract

In this study, it was aimed to develop a vaccine attitude scale. This scale has the potential to aid in the advancement of research and immunization policy. We carried out exploratory factor analysis (EFA) to discover the uncovered dimensions and confirmatory factor analysis (CFA) to validate the obtained structures in vaccine attitude scale. Also, we checked the reliabilities with Cronbach Alpha coefficients for each factor. The results revealed that the vaccine attitude scale can be represented with three factors such as the benefits, acceptance and hesitation of the vaccine. We observed positive relationship between benefits-acceptance and an acceptance-hesitation factor but there is negative relationship between benefits-hesitation in vaccine attitude scale. The dimension of the vaccine attitude scale was found reliable and valid as the results of the statistical analysis. This improved scale was found fairly high in terms of validity and reliability. Besides, it is found that it is a valid and reliable measurement tool to determine vaccine attitude of the individuals.
