The present study aimed (1) to identify distinct latent classes of motivation to get vaccinated against coronavirus disease 2019 (COVID-19) and previous seasonal influenza vaccination among people in Taiwan and (2) to examine the roles of sources of information, risk perception, and cognitive appraisals of vaccination against COVID-19 in these classes. We recruited 1047 participants through a Facebook advertisement. The participants' motivation to get vaccinated against COVID-19, previous seasonal influenza vaccination, sources of information about COVID-19 vaccination, risk perception of COVID-19, and cognitive appraisals of vaccination against COVID-19 were determined. We examined the participants' motivation for COVID-19 vaccination and previous seasonal influenza vaccination through latent profile analysis. Four latent classes of motivation were identified: participants with high motivation for COVID-19 vaccination and high seasonal influenza vaccination, those with high motivation for COVID-19 vaccination but low seasonal influenza vaccination, those with low motivation for COVID-19 vaccination but high seasonal influenza vaccination, and those with low motivation for COVID-19 vaccination and low seasonal influenza vaccination. Compared with participants in the latent class of high motivation for COVID-19 vaccination and high seasonal influenza vaccination, those in the other three latent classes had lower levels of positive appraisals of COVID-19 vaccination; participants in the latent class of low motivation for COVID-19 vaccination and low seasonal influenza vaccination had lower risk perception of COVID-19 and were also less likely to obtain information about COVID-19 vaccination from the internet, friends, and family members. The various motivations and behaviors for vaccination, sources of information, risk perception, and cognitive appraisals of vaccination against COVID-19 should be considered in intervention programs aiming to increase people's motivation to get vaccinated against COVID-19.
（1）识别台湾民众中针对2019冠状病毒病（COVID-19）和既往季节性流感疫苗接种的不同潜在动机类别；（2）考察这些类别中COVID-19疫苗接种的信息来源、风险认知和认知评估的作用。我们通过脸书广告招募了1047名参与者。确定了参与者接种COVID-19疫苗的动机、既往季节性流感疫苗接种情况、COVID-19疫苗接种的信息来源、对COVID-19的风险认知以及对COVID-19疫苗接种的认知评估。我们通过潜在剖面分析考察了参与者接种COVID-19疫苗和既往季节性流感疫苗的动机。识别出了四类潜在动机：COVID-19疫苗接种和季节性流感疫苗接种动机均高的参与者、COVID-19疫苗接种动机高但季节性流感疫苗接种动机低的参与者、COVID-19疫苗接种动机低但季节性流感疫苗接种动机高的参与者、以及COVID-19疫苗接种和季节性流感疫苗接种动机均低的参与者。与COVID-19疫苗接种和季节性流感疫苗接种动机均高的潜在类别中的参与者相比，其他三个潜在类别中的参与者对COVID-19疫苗接种的积极评估水平较低；COVID-19疫苗接种和季节性流感疫苗接种动机均低的潜在类别中的参与者对COVID-19的风险认知较低，也不太可能从互联网、朋友和家庭成员那里获取COVID-19疫苗接种的信息。在旨在提高人们接种COVID-19疫苗动机的干预项目中，应考虑针对COVID-19疫苗接种的各种动机和行为、信息来源、风险认知和认知评估。
