RESUMO
Background and aimFollowing emergency approval of vaccines, the amount of scientific literature investigating population hesitancy towards vaccination against the novel coronavirus disease (COVID-19) has increased exponentially. Nevertheless, the associated psychological behaviors with this phenomenon are still not clearly understood. This study aims to assess the psychological antecedents of the Arab population toward COVID-19 vaccines. MethodsA cross-sectional, online study using a validated Arabic version of the 5C questionnaire was conducted through different media platforms in different Arabic-speaking countries. The questionnaire included three sections: socio-demographics, COVID-19 related questions, and the 5C scale of vaccine psychological antecedents, namely confidence, complacency, constraints, calculation, and collective responsibility. ResultsA total of 4,474 participants, 40.8% males from 13 Arab countries were included in the study. About 26.7% of participants had confidence in COVID-19 vaccination, 10.7% had complacency, 96.5% had no constraints, 48.8% had calculation and 40.4% had collective responsibility. The 5C antecedents showed variation among countries with confidence and collective responsibility being higher in the United Arab Emirates (UAE) (59% and 58%, respectively), complacency and constraints were higher in Morocco (21% and 7%, respectively) and calculation was higher in Sudan (60%). Regression analysis revealed that sex, age, educational degrees, being a health care professional, getting a COVID-19 infection, having a relative infected or died from COVID-19 can affect the 5C psychological antecedents by different degrees. Conclusion and recommendationsWide variations of psychological antecedents between Arab countries exist. Different determinants can affect vaccine psychological antecedents.
RESUMO
BackgroundOne of the newly faced challenges during the COVID-19 is vaccine hesitancy (VH). The validated 5C scale, that assesses five psychological antecedents of vaccination, could be effective in exploring COVID-19 VH. This study aimed to determine a statistically valid cutoff points for the 5C sub-scales among the Arab population. MethodsA cross-sectional study was conducted among 446 subjects from three Arab countries (Egypt, United Arab Emirates UAE, and Jordan). Information regarding sociodemographics, clinical history, COVID-19 infection and vaccination history, and 5C scale were collected online. The 5C scores were analyzed to define the cutoff points using the receiver operating characteristic curve (ROC) and to verify the capability of the questionnaire to differentiate whether responders are hesitant or non-hesitant to accept vaccination. ROC curve analysis was conducted setting for previous vaccine administration as a response, with the predictors being the main five domains of the 5C questionnaire. The mean score of each sub-scale was compared with COVID-19 vaccine intake ResultsThe mean age of the studied population was 37{+/-}11, 42.9% were males, 44.8% from Egypt, 21.1% from Jordan, and 33.6% from UAE. Statistically significant differences between vaccinated and unvaccinated participants, respectively, weredetetd in the median score of confidence [6.0(1.3) versus 4.7(2.0)], complacency [(2.7(2.0) versus 3.0(2.0), constraints [1.7(1.7) versus 3.7(2.3)], and collective responsibility [6.7(1.7) versus 5.7(1.7)]. The area under the curve of the five scales was 0.72, 0.60, 0.76, 0.66, 0.66 for confidence, complacency, constraints, calculation, and collective responsibility at cutoff values of 5.7, 4.7, 6.0, 6.3, and 6.2, respectively. Conclusionthe Arabic validated version of the 5C scale has a good discriminatory power to predict COVID-19 vaccines antecedent.
