Primary Outcome Measures
NameTimeMethod
The primary outcome of this study is the effectiveness of the SAS intervention video in increasing knowledge about the COVID-19 vaccine. While knowledge alone is insufficient to modify health behaviors, it is vital for individuals to access and comprehend their health options in order to exert greater control over their health decisions. Furthermore, we will measure changes in behavioral intent toward the COVID-19 vaccination. According to the Theory of Planned Behavior (TPB), the intention to act is considered the immediate determinant of action. In this study, behavioral intent is defined as a participant's commitment to receive the COVID-19 vaccine and to seek information about the vaccine during the next two weeks. In addition, we will evaluate participant willingness to voluntarily engage with the SAS intervention videos (post-trial access to treatment) to determine whether SAS videos may have the potential to generate interest as a precursor for health promotion and communication.
Secondary Outcome Measures
NameTimeMethod
We will explore the differences in individual factors related to the levels of vaccine hesitancy between the vaccinated and unvaccinated populations. To do so, we will first compute a comprehensive score for each individual factor which are: perception of risk and benefit, attitude, self-efficacy, perceived social norms, and trust. We will then inspect correlations between such factors and participants’ vaccination status using OLS models. <br>
