| Résumé : |
Background: Healthcare workers (HCW) are a priority group to vaccinate against COVID-19 to prevent disease-related absenteeism and nosocomial infection. The start of the COVID-19 vaccination campaign among HCW in France offered an opportunity to explore the antecedents of vaccine hesitancy (VH), in particular their extension from the 5C model (complacency, confidence, convenience, calculation, collective responsibility) to a 7C model, including social conformism and confidence in the system and the how much individual items explain VH within socio- professional demographic determinants. Furthermore, understanding the role of knowledge in vaccine intention.
Methods:We developed a knowledge and attitude (KA) questionnaire with 30 items relating to the 7 components of psychological antecedents. The questionnaire was administered online among a snowballing sample of French healthcare workers, recruited in December 2020-January 2021 through professional organizations. We used multivariate logistic regression to explore the association of 7C components and individual KA items with COVID-19 vaccine intention. For alternative analyses, knowledge items were grouped into a separate knowledge score to see the effects of knowledge separate from the attitude items. A mediation analysis was conducted to evaluate which KA-7C items can explain socio- professional demographic determinants of COVID-19 vaccine intention. Results:Among the 5234 participants, the vaccine intention model fits (pseudo R-squared values) ranged from R2=0.48 for Calculation to R2=0.07 for Convenience, with R2=0.29 for Confidence in System and R2=0.26 for Social Conformism. In nested models including the initial 5C components, adding Confidence in System increased the model fit significantly from R2=0.60 to 0.61 (p<0.001), and Social Conformism from R2=0.60 to 0.62 (p<0.001). In multivariate models including a shortlist of 15 items, the strongest association with vaccine intention was observed for a positive attitude on the vaccine’s benefit-risk balance (strongly agree vs. strongly disagree: odds ratio 16.81, 95%-confidence interval 9.66-29.25). In a 7C model without the knowledge items, adding a knowledge score did not increase the model fit substantially (both R2=0.64). In mediation analyses keeping the basic model of socio- professional determinants, 98.2% COVID-19 vaccine intention in nursing assistants compared to nurses could be explained by including collective action to stop the epidemic and the professional environment opinion. Meanwhile, 95.6% of vaccine intention in medical professionals were explained by 10 items. Discussion:The results suggest that social conformism and confidence in the system are essential independent antecedents of VH, knowledge does not have as strong of an influence, and which items in the KA-7C antecedents explain COVID-19 vaccine intention. These results can aid in better understanding the psychological antecedents that influence VH against COVID-19 vaccination among HCW. |
