description En estos tiempos de pandemia, la aceptación o rechazo de las vacunas se ha hecho cada vez más evidente, con un aumento considerable del movimiento antivacunas en España. Es importante comprender las actitudes que llevan a una persona a rechazar la vacunación para desarrollar campañas de salud pública más efectivas. El objetivo de este estudio ha sido estudiar las propiedades psicométricas y la invariancia de medida de la escala Vaccination Attitudes Examination (VAX) en una muestra española. El análisis factorial confirmatorio y el modelado de ecuaciones estructurales se han utilizado para estudiar las propiedades psicométricas del VAX. Asimismo, se ha estudiado la invariancia de medida por sexo y nivel educativo. Se confirma la estructura de cuatro factores relacionados para VAX, así como su valor predictivo, ya que el factor “confianza en el beneficio de la vacuna” predice claramente la elección de vacunarse. También se confirma la fuerte invariancia de medida por género y nivel educativo. La comparación de medias latentes entre grupos indica que no existen diferencias por género en ningún factor. Sin embargo, las personas con un nivel educativo alto presentan puntuaciones más altas en los factores “preocupación por los efectos futuros imprevistos”, “preocupación por los efectos comerciales y la especulación” y “preferencia por la inmunidad natural”. El VAX se presenta como una herramienta fiable y válida para evaluar cuatro factores diferentes relacionados con las actitudes hacia las vacunas en España. Los estudios futuros de su invariancia transcultural pueden ayudar a determinar los principales factores que llevan a las personas a no vacunarse para desarrollar campañas de salud pública más efectivas.

It is important to understand the attitudes that lead a person to refuse vaccination in order to develop more effective public health campaigns. The objective of this study has been to study the psychometric properties and measurement invariance of the Vaccination Attitudes Examination (VAX) scale in a Spanish sample. Confirmatory factor analysis and structural equation modelling have been used to study the psychometric properties of the VAX. Likewise, the measurement invariance by gender and educational level has been studied. The structure of four related factors for VAX is confirmed, as well as its predictive value, since the factor “trust in the benefit of the vaccine” clearly predicts the choice to be vaccinated. The strong measurement invariance by gender and educational level is also confirmed. The comparison of latent means between groups indicates that there are no differences by gender in any factor. However, people with a high educational level present higher scores in factors “concern about unforeseen future effects”, “concern about commercial effects and speculation” and “preference for natural immunity”. The VAX is presented as a reliable and valid tool to assess four different factors related to attitudes towards vaccines in Spain. Future studies of its cross-cultural invariance may help to determine the main factors that lead people not to be vaccinated in order to develop more effective public health campaigns.https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001561776https://orcid.org/0000-0002-6337-577Xmartha.martinc@campusucc.edu.co10Universidad Cooperativa de Colombia, Facultad de Ciencias Sociales, Psicología, Santa MartaPsicologíaSanta Martahttps://bmcpsychology.biomedcentral.com/articles/10.1186/s40359-022-00929-yBMC PsychologyKennedy J.
