ABSTRACT
COVID-19 vaccines are put forward as the most promising solution for combatting the COVID-19 pandemic. This study aims to assess the willingness to get vaccinated against COVID-19 by using the Health Belief Model (HBM) and the Theory of Planned Behavior (TPB) as a theoretical framework. A self-administered questionnaire was considered among Vietnamese adult patients between March and May 2021. The dependent variable was a COVID-19 vaccine acceptance, the hierarchical multivariable regression was done to assess the fit of the predictor model and the associations of variables. A total of 462 participants completed the questionnaire, with 80.5% vaccination intention. A model containing demographics, as well as HBM and TPB variables, demonstrated to be a predictor of intention to receive a COVID-19 vaccine, interpreting 39% of the variance (adjusted R 2 = 0.39). For HBM and TPB constructs, respondents were more likely to accept vaccination if they had higher level of cues to action, self-efficacy, and a lower level of the perceived barriers (all P < .001). The theoretical framework provided a predictor of intention to get a COVID-19 vaccine, which is important for elaborating intervention plans to ensure the success of conducting mass vaccination campaigns.
ABSTRACT
BACKGROUND: Healthcare students are a force that will aid healthcare workers in responding to the COVID-19 pandemic. This study aims to evaluate the knowledge, attitude, and preventive practices (KAP) towards COVID-19 for this population in Vietnam. METHODS: An online-based cross-sectional survey was considered with all students at the University of Medicine and Pharmacy in Ho Chi Minh City (UMP), Vietnam, between June and August 2020. A structured questionnaire was used to assess KAP towards COVID-19 with response having considerable data missing in the areas of KAP being excluded from the analysis. All data were analysed by using STATA 14 software, to determine the factors associated with preventive practices, and a multivariable regression analysis was performed, along with odds ratio (OR) and 95% confidence interval (95% CI). RESULTS: A total of 2351 eligible participants completed the survey, 65.6% of whom were female, and their mean age was 21.9 years old (SD = 2.7). Almost all had sufficient knowledge (86.6%) and good preventive practice (92.8%) towards COVID-19; however, there was also a rather low level of positive attitude recorded, at 68.8%. The multivariable logistic regression analysis showed that the female participants, and the receiving of information from the official websites, reported a significantly higher level of good practice. Besides, students who had a high level of sufficient knowledge and positive attitude towards COVID-19 were more likely to have good preventive practices (All p<0.001). CONCLUSION: The findings demonstrated good preventive practice towards COVID-19; however, sufficient knowledge and positive attitude were lower. Therefore, it is an identified requirement to continue with additional education and training strategies to offer a better understanding and positive viewpoint of the pandemic for all students, including healthcare students.
