Abstract

Background

Marginalized communities have been disproportionately impacted by COVID-19. In Michigan as of 2024, while 59% of Hispanic people, 46% of African American people, and 56% of White people received at least one dose of vaccine, only 8% of African American and 8% of Hispanic residents report being up-to-date, per CDC definition, compared to 13% of White residents. The goals of the project were to increase vaccine uptake through the implementation and evaluation of a tailored behavioral intervention.

Methods

This group-tailored digital intervention investigates the effect of an SMS-based health education program on vaccine intent in African American and Latino/Hispanic individuals. Recruited in-person and digitally throughout Michigan, 1327 participants were randomized into two arms, and then stratified into four audience segment groups based on vaccine readiness. The primary aim of the study is to increase uptake of the COVID-19 vaccine following receipt of the tailored text messages. Participants were evaluated pre- and post-intervention for intent to vaccinate, perceptions of barriers to vaccination, attitudes towards the vaccine, and knowledge of common vaccine misinformation.

Discussion

This study will inform future literature in addressing vaccine hesitancy for racial and ethnic populations, the use of motivational interviewing-based interventions, and digital health interventions in general.

通过基于动机性访谈的量身定制数字干预提高COVID-19疫苗的吸收率：研究方案。

背景：边缘化社区受到COVID-19的不成比例的影响。在密歇根州，截至2024年，59%的西班牙裔美国人、46%的非洲裔美国人和56%的白人至少接种了一剂疫苗，但根据疾病预防控制中心的定义，只有8%的非洲裔美国人和8%的西班牙裔居民报告接种了最新疫苗，而白人居民的这一比例为13%。该项目的目标是通过实施和评估量身定制的行为干预措施来提高疫苗的吸收率。方法：这个群体定制的数字干预调查了基于短信的健康教育计划对非裔美国人和拉丁裔/西班牙裔个体疫苗意向的影响。1327名参与者在密歇根州进行了面对面和数字化招募，随机分为两组，然后根据疫苗准备情况分为四个受众群体。该研究的主要目的是在收到量身定制的短信后增加COVID-19疫苗的吸收量。在干预前和干预后对参与者进行评估，以了解疫苗接种的意图、对疫苗接种障碍的认识、对疫苗的态度以及对常见疫苗错误信息的了解。讨论：这项研究将为未来的文献提供信息，以解决种族和民族人群的疫苗犹豫问题，使用基于动机访谈的干预措施，以及一般的数字健康干预措施。

期刊介绍： Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome.
