背景马来西亚有一个全面的，公共资助的婴儿B型肝炎（HepB）免疫接种计划，但成年人必须支付疫苗费用。预计未来成年人中HepB携带者的数量将增加;因此，我们研究了五种结构的影响。（行动线索、感知障碍、感知利益、感知严重性和感知易感性）对成人乙肝疫苗支付意愿的影响;其次，我们研究了感知障碍和感知利益之间的关联。马来西亚雪兰莪州的两阶段集群社区样本。测量模型的可靠性，收敛效度，判别效度进行了评估，然后实施偏最小二乘结构方程模型（PLS-SEM），以评估结构paths.ResultsA的意义，共728名参与者被招募。五个构念均显示出足够的内部信度、聚合效度和区分效度。结构与支付意愿之间存在显著的正相关（感知障碍[路径系数（beta）= 0.082，P= 0.036]，感知易感性[beta = 0.214，P
BackgroundMalaysia has a comprehensive, publicly-funded immunization program for hepatitis B (HepB) among infants, but adults must pay for the vaccine. The number of HepB carriers among adults is expected to increase in the future; therefore, we examined the impact of five constructs (cues to action, perceived barriers, perceived benefit, perceived severity, and perceived susceptibility) on adults' willingness to pay (WTP) for HepB vaccine; secondarily, we examined the association between perceived barriers and perceived benefits.MethodsAdults were selected through a stratified, two-stage cluster community sample in Selangor, Malaysia. The reliability, convergent validity, and discriminant validity of the measurement model were assessed before implementing a partial least squares structural equation model (PLS-SEM) to evaluate the significance of the structural paths.ResultsA total of 728 participants were enrolled. The five constructs all showed adequate internal reliability, convergent validity, and discriminant validity. There was a significant, positive relationship to WTP from constructs (perceived barriers [Path coefficient (beta) = 0.082, P= 0.036], perceived susceptibility [beta = 0.214, P
