The World Health Organization (WHO) proposed COVID-19 vaccination as an emergent and important method to end the COVID-19 pandemic. Since China started vaccination programs in December 2020, vaccination has spread to provinces and municipalities nationwide. Previous research has focused on people's vaccination willingness and its influencing factors but has not examined vaccination behavior. We examine the effectiveness of psychosocial factors in predicting vaccination behavior.
A cross-sectional online survey was performed among Chinese adults on 8 May and 4 June 2021. The statistical analysis of the data included univariate analysis, receiver operator characteristics (ROC) analysis and ordinal multiclassification logistic regression model analysis.
Of the 1300 respondents, 761 (58.5%) were vaccinated. Univariate analysis showed that a high education level and good subjective health status were protective factors for vaccination behavior, while suffering from chronic diseases was a risk factor. ROC analysis showed that subjective health status (AUC = 0.625, 95% CI: 0.594-0.656, P < 0.001) was the best predictor of vaccination behavior. Logistic regression analysis with subjective health status as a dependent variable indicated that older age, female sex, depression, neurasthenia, obsession, hypochondriasis and chronic disease were significant risk factors, while positive coping tendencies were a significant protective factor.
Our study found a simple and effective marker, subjective health status, that can predict vaccination behavior. This finding can guide future epidemic prevention work.
世界卫生组织（WHO）提出新冠病毒疫苗接种是结束新冠疫情大流行的紧急而重要的方法。自 2020 年 12 月中国启动疫苗接种计划以来，疫苗接种已在全国各省、市普及。既往研究主要关注人们的疫苗接种意愿及其影响因素，但尚未对疫苗接种行为进行研究。本研究旨在检验社会心理因素对预测疫苗接种行为的有效性。
本研究于 2021 年 5 月 8 日和 6 月 4 日通过在线横断面调查的方式，对中国成年人进行调查。数据分析采用单因素分析、受试者工作特征曲线（ROC）分析和有序多分类 logistic 回归模型分析。
在 1300 名受访者中，761 人（58.5%）已接种疫苗。单因素分析显示，高学历和良好的主观健康状况是疫苗接种行为的保护因素，而患有慢性病是风险因素。ROC 分析显示，主观健康状况（AUC=0.625，95%CI：0.594-0.656，P<0.001）是疫苗接种行为的最佳预测指标。以主观健康状况为因变量的 logistic 回归分析表明，年龄较大、女性、抑郁、神经衰弱、痴迷、疑病症和慢性病是显著的风险因素，而积极的应对倾向是显著的保护因素。
本研究发现，主观健康状况是一种简单有效的预测疫苗接种行为的标志物。这一发现可以为未来的疫情防控工作提供指导。
