Determinants Influenced by COVID-19 Vaccine: Employing the Health Action Process Approach and the Belief in Conspiracy Theories

Abstract

Vaccination is considered a practical approach to improving individuals’ health behavior to fight against the COVID-19 pandemic. However, the currently manufactured COVID-19 vaccines can only work for a limited time. Thus, continuous vaccination intention is crucially essential. The current study explores critical factors influencing citizens’ continuous vaccination intentions for COVID-19 vaccines, based on the modified health action process approach (HAPA) model and belief in a conspiracy theory. A questionnaire survey was used to collect data from people living in Taiwan. Three hundred ninety responses were employed for the final investigation. The findings suggest that openness to experience, government communication, and pandemic knowledge significantly influence vaccination intention, but the COVID-19 threat is insignificant. Second, descriptive norms play a significant role in promoting vaccination intention. Third, a belief in conspiracy theories negatively influences vaccination intention. Fourth, vaccination behavior positively influences both perceived benefits and value co-creation. Fifth, perceived benefits positively impact value co-creation and continuous vaccination behavior. Finally, value co-creation has a significant influence on continuous vaccination behavior. The proposed model, the key contributor to the current study, confirms citizens’ continuous vaccination intentions in a three-stage procedure: motivation to volitional, volitional to behavior, and volitional to continuous vaccination intention.

Big Five personality traits and vaccination: A systematic review and meta-analysis

“…The geographical distribution of these studies was diverse, with no single country contributing more than two studies except the United States. The majority originated from Western cultures (19), but there were also contributions from Mainland China (Mo et al, 2021;Zhang et al, 2022), India (Khurana et al, 2022), Indonesia (Yanto et al, 2021), Peru (Hervais-Guerra et al, 2023), Qatar (Reagu et al, 2023), South Korea (Ryu et al, 2023), and Taiwan (Dutta, 2023;Lee et al 2022). Most studies utilized convenience or random samples (21), with a smaller proportion using representative samples (Dutta, 2023;Halstead et al, 2022;Lin & Wang, 2020;Mo et al, 2021;Murphy et al, 2021;Stahlmann et al, 2023); one was unspecified (Patzina & Dietrich, 2022).…”
