ABSTRACT
Young adults have been one of the lowest vaccinated groups against COVID-19 in the U.S. Since information seeking intention is closely related to individual’s behavior intention, this study used expanded theory of planned behavior model to explain COVID-19 vaccine information seeking intention among young adults. Results suggested that attitudes, subjective norms, self-efficacy, perceived susceptibility, and political view were significantly associated with information seeking intention while anticipated regret was not significantly associated with information seeking intention. The overall model contributed a substantive part of variance of information seeking intention (R2 = 0.58). Implications for public health communication strategies and vaccination campaigns were discussed. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
