The studies reviewed used diverse methods of varying quality. There is need for consensus among researchers in how to achieve quality of instrument translation in cross-cultural research. Researchers should carefully attend to achieving and reporting evidence of the accuracy and validity of instrument translation. When back-translation fails to achieve semantic equivalence, the instrument development process should be replicated in the target language.
Adherence was high in this cohort and was associated with HIV-RNA levels. However, these data confirm that adherence is only 1 factor that determines the effectiveness of ARV treatment. Duration of treatment was associated with virologic failure, controlling for adherence.
Introduction
Unvaccinated older adults with COVID-19 are at higher risk for severe illness and complications compared with those have been vaccinated. Vaccine literacy and attitudes are important factors that enhance healthy behaviors and choices, including vaccination intention.
Objective
To explore vaccine literacy, attitudes, and vaccination intention toward COVID-19 among Thai older adults and examine associations between vaccine literacy, attitudes, and vaccination intention.
Methods
This study used a cross-sectional online design. We surveyed 408 older adults who met our inclusion criteria. Participants were recruited online via social media and websites. The survey covered demographic data, vaccine literacy, attitudes, and intention to get the COVID-19 vaccine.
Results
COVID-19 vaccination intention among Thai older adults was high (81.3%). Females and those aged 60–69 years had higher COVID-19 vaccine literacy scores than males (t = −2.120, p < 0.05) and those aged ≥70 years (t = 2.438, p < 0.05). Participants with postgraduate education and those who were health professionals scored higher for vaccine literacy than less educated (t = −3.501, p < 0.01) and non-health professional (t = 5.437, p < 0.001) participants. Those with an adequate income or that had been vaccinated against COVID-19 scored significantly higher for vaccine literacy and attitudes toward the COVID-19 vaccine than participants with an inadequate income (t = 4.626, p < 0.001) or that had not been vaccinated (t = 2.842, p < 0.01). Vaccine literacy (r = 0.219, p < 0.001) and attitudes (r = 0.459, p < 0.001) were significantly associated with vaccination intention.
Conclusion
COVID-19 vaccine literacy and attitudes are significant factors related to vaccination intention. Health professionals could play an important role in enhancing vaccine literacy among older adults. Positive attitudes and COVID-19 vaccine literacy may enhance vaccination uptake in older adults.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
