Abstract

Objectives: This study aimed to assess the impact of high-level versus low-level construal messages about the coronavirus disease 2019 (COVID-19) Vaccine Injury Compensation Program (CVICP) on public attitudes toward the program and COVID-19 vaccination.

Methods: A randomized controlled experimental design was employed. Adults aged 18 to 64 residing in the Republic of Korea were randomly assigned to either an experimental group (high-level construal message) or a control group (low-level construal message). Both groups viewed a 2-minute video about the CVICP, with construal level as the sole variable. Pre- and post-intervention questionnaires evaluated attitudes toward the CVICP and COVID-19 vaccination, including satisfaction, perceived necessity, and perceived effectiveness in enhancing vaccine acceptance. Data were analyzed using the paired t-test, repeated measures 2-way analysis of variance, and multiple linear regression.

Results: The experimental group showed statistically significant improvements across all 6 attitude measures following exposure to the high-level construal message. By contrast, the control group demonstrated significant improvement in only 3 attitudes: satisfaction with the CVICP, willingness to recommend vaccination, and willingness for future vaccination. A significant difference between groups was observed for perceived effectiveness of the CVICP in enhancing vaccine acceptance (p=0.01), with high-level construal messaging being more impactful.

Conclusion: High-level construal messages are more effective than low-level messages in shaping public perceptions and addressing vaccine hesitancy. Policymakers and health authorities should incorporate high-level construal elements into communication strategies to build trust and support for vaccination programs.

韩国COVID-19疫苗伤害赔偿计划中识解水平信息传递的比较有效性:一项随机对照试验
目的:本研究旨在评估关于2019冠状病毒病(COVID-19)疫苗伤害赔偿计划(CVICP)的高水平和低水平解释信息对公众对该计划和COVID-19疫苗接种态度的影响。方法:采用随机对照试验设计。居住在大韩民国的18至64岁的成年人被随机分配到实验组(高水平解释信息)和对照组(低水平解释信息)。两组都观看了一个关于CVICP的2分钟视频,解释水平是唯一的变量。干预前和干预后问卷评估了对CVICP和COVID-19疫苗接种的态度,包括满意度、感知必要性和感知有效性,以提高疫苗接受度。数据分析采用配对t检验、重复测量、双向方差分析和多元线性回归。结果:实验组在接触高水平解释信息后,在所有6项态度测量中均显示出统计学上显著的改善。相比之下,对照组仅在3个态度上表现出显著改善:对CVICP的满意度、推荐接种疫苗的意愿和未来接种疫苗的意愿。CVICP在提高疫苗接受度方面的感知有效性在两组之间存在显著差异(p=0.01),高水平的解释信息更有影响力。结论:在塑造公众观念和解决疫苗犹豫问题方面,高水平的解释信息比低水平的信息更有效。决策者和卫生当局应将高层解释因素纳入沟通战略,以建立对疫苗接种规划的信任和支持。
