We evaluated the influence of psychosocial factors on HBV screening.
Sample consisted of 1716 Vietnamese participants in our previous HBV intervention trial, recruited from 36 community-based organizations in Pennsylvania, New Jersey, and New York City between 2009 and 2014. Using the Health Belief Model and Social Cognitive Theory, we measured self-efficacy, knowledge, perceived barriers, perceived benefits, perceived severity, and risk susceptibility. Analysis of covariance was used to compare pre- and post-intervention changes of psychosocial variables. Structural equation modeling was used to explore the direct and indirect effects of the psychosocial variables on HBV screening.
Knowledge, self-efficacy, perceived benefits, and perceived barriers were directly associated with HBV screening; knowledge had the strongest effect. Perceived severity and risk susceptibility had indirect association with HBV screening through other variables. Indirect paths among the 6 psychosocial variables were also identified.
To promote HBV screening among Vietnamese Americans, intervention efforts should focus on increasing knowledge, self-efficacy, and perceived benefits, decreasing perceived barriers, and accounting for the dynamic cognitive processing.
我们评估了社会心理因素对乙肝病毒（HBV）筛查的影响。
样本包括1716名参与我们之前HBV干预试验的越南裔参与者，他们于2009年至2014年间从宾夕法尼亚州、新泽西州和纽约市的36个社区组织招募而来。我们运用健康信念模型和社会认知理论，测量了自我效能感、知识水平、感知障碍、感知益处、感知严重性和风险易感性。协方差分析用于比较干预前后社会心理变量的变化。结构方程模型用于探究社会心理变量对HBV筛查的直接和间接影响。
知识水平、自我效能感、感知益处和感知障碍与HBV筛查直接相关；知识水平的影响最强。感知严重性和风险易感性通过其他变量与HBV筛查存在间接关联。还确定了6个社会心理变量之间的间接路径。
为促进美籍越南人进行HBV筛查，干预措施应侧重于增加知识、自我效能感和感知益处，减少感知障碍，并考虑动态认知过程。
