Intención de vacunarse contra COVID-19 en la población de 40 años en adelante en México

Objetivo Evaluar el efecto de las fuentes de información sobre COVID-19, los beneficios y las barreras percibidas de la vacunación, y la actitud hacia la vacunación sobre la intención de vacunarse contra COVID-19 en la población de 40 años en adelante en México. Métodos Se desarrolló una investigación cuantitativa, transversal y explicativa. Se aplicó una encuesta electrónica a 703 personas de 40 años en adelante que residen en México. El análisis de resultados se realizó a través de la técnica de ecuaciones estructurales por medio del método de mínimos cuadrados parciales. Resultados Las fuentes de información sobre COVID-19 influyen positivamente sobre los beneficios percibidos de la vacuna y disminuyen las barreras percibidas. Además, los beneficios percibidos influyen positivamente sobre la actitud hacia la vacunación de COVID-19; sin embargo, las barreras no afectan la actitud. Adicionalmente, esta última influye en la intención de vacunarse contra COVID-19 e, indirectamente, las fuentes de información y los beneficios percibidos influyen sobre la intención a vacunarse mediados por la actitud.

Objective To evaluate the effect of information sources on COVID-19, the benefits and perceived barriers of vaccination, and the attitude towards vaccination on the intention to get vaccinated against COVID-19 in the population aged 40 and over in Mexico. Methods A quantitative, cross-sectional and explanatory investigation was developed. An electronic survey was applied to 703 people aged 40 and over who reside in Mexico. The analysis of results was carried out through the technique of structural equations by means of the method of partial least squares. Results The sources of information on COVID-19 positively influence the perceived benefits of the vaccine and reduce the perceived barriers. Furthermore, the perceived benefits positively influence the attitude towards COVID-19 vaccination; however, barriers do not affect attitude. Additionally, the latter influences the intention to be vaccinated against COVID-19 and indirectly the sources of information and the perceived benefits influence the intention to be vaccinated mediated by the attitude.

Severidad, susceptibilidad y normas sociales percibidas como antecedentes de la intención de vacunarse contra coviD-19 / Severity, susceptibility and social norms perceived as antecedents of the intention to be vaccinated against COVID-19

RESUMEN Objetivo Evaluar el efecto del riesgo y las normas sociales percibidos sobre la COVID-19 y sobre la intención de vacunarse si se contara con una vacuna para prevenir la infección. Métodos Se desarrolló una investigación cuantitativa, explicativa y con diseño transversal. Los datos se recopilaron mediante un cuestionario estructurado aplicado de manera electrónica a habitantes de más de 18 años de edad en el estado de Puebla, en México. Se utilizó un análisis con ecuaciones estructurales para identificar los efectos entre las variables estudiadas. Resultados Tanto la severidad como la susceptibilidad percibidas al contraer COVID-19 tuvieron un efecto positivo sobre las normas sociales percibidas sobre el virus. Mientras la severidad percibida tuvo un efecto positivo sobre la intención de vacunarse, la susceptibilidad percibida resultó no significativa sobre la intención de vacunarse contra COVID-19. Conclusiones La intención de vacunarse contra COVID-19 es afectada por la severidad y las normas sociales percibidas por contraer la infección. Sin embargo, la susceptibilidad percibida ante el virus no tiene un efecto sobre la intención de vacunarse.(AU)

ABSTRACT Objective To evaluate the effect of perceived risk and social norms on COVID-19 and on the intention to be vaccinated if a vaccine were available to prevent infection. Methods A quantitative, explanatory and cross-sectional research was developed. The data was collected through a structured questionnaire applied electronically to inhabitants over 18 years of age in the state of Puebla in Mexico. An analysis with structural equations was used to identify the effects among the constructs studied. Results The results showed that both the perceived severity and susceptibility of contracting COVID-19 had a positive effect on the perceived social norms about the virus. Also, while the perceived severity had a positive effect on the intention to vaccinate, the perceived susceptibility was not significant on the intention to vaccinate against COVID-19. Conclusion Intention to be vaccinated against COVID-19 is affected by the severity and perceived social norms of contracting the infection. However, the perceived susceptibility to the virus does not have an effect on the intention to be vaccinated.(AU)
