Health information seeking and scanning are two important information acquisition strategies that can influence subsequent health behaviors. This research was contextualized in COVID-19 vaccinations and examined the effects of information seeking and scanning on vaccination intention among unvaccinated Black Americans (N = 1,278). Moreover, this research conceptualized perceived risk and efficacy as the intervening factors for the relationship between information acquisition and behavioral intention. The results indicated that information seeking had a significant effect on vaccination intention, whereas information scanning had no effect. Perceived susceptibility and response efficacy mediated the relationship between information seeking and vaccination intention. The proposed mediators did not mediate the relationship between information scanning and vaccination intention. Theoretical and practical implications are offered.

健康信息搜索和扫描是影响后续健康行为的两种重要的信息获取策略。这项研究以 COVID-19 疫苗接种为背景，并检查了信息搜索和扫描对未接种疫苗的美国黑人疫苗接种意图的影响 ( N= 1,278）。此外，本研究将感知风险和效能概念化为信息获取与行为意图之间关系的干预因素。结果表明，信息搜索对疫苗接种意愿有显着影响，而信息扫描则没有影响。感知易感性和反应效能在信息寻求和疫苗接种意向之间的关系中起中介作用。拟议的调解人没有调解信息扫描和疫苗接种意向之间的关系。提供了理论和实践意义。
