概括

在一项大型试验中,个性化的提醒,而不是小规模的财务激励,有效地提高了COVID-19疫苗接种率. 这一发现为公共卫生提供了一个低成本的策略,以增加高风险人群的疫苗接种率.

科学领域:

公共卫生公共卫生
流行病学流行病学
行为科学行为科学

背景情况:

在全球范围内,尽管在减少严重疾病和死亡率方面已被证明有效,但COVID-19增强疫苗接种率仍然很低.
确定有效的策略来增加增强剂的吸收,特别是在高风险的人群中,对公共卫生至关重要.
之前的干预措施在促进接种疫苗的坚持方面显示出不同的结果.

研究的目的:

评估个性化提醒信息和财政激励措施在提高COVID-19增强疫苗接种率方面的有效性.
确定这些干预措施对大量,多样化的人口中接种疫苗的影响.
为公共卫生活动提供以证据为基础的建议,旨在改善补充疫苗接种范围.

主要方法:

一个大规模的,预先注册的随机受控试验,涉及57,893名参与者,在加利福尼亚州北部的卫生系统中进行.
与对照组相比,参与者被随机分配,接受个性化的提醒信息,25美元的经济激励,或两者的组合.
在干预后的两周内,评估了补充疫苗接种率.

主要成果:

个性化提醒信息显著增加了0.86个百分点 (P = 0.000) 的增强疫苗接种率,比对照组的2.65%的平均率增加了近33% (P = 0.000).
与单独的提醒或对照组相比,小规模的财政激励 (25美元) 并没有显示出任何额外的显著影响,这与提醒或对照组相比,对补充疫苗接种率没有任何显著影响.
这项研究强调了低成本,有针对性的沟通策略在影响健康行为的有效性.

结论:

个性化提醒信息是提高COVID-19增强疫苗接种率的成本效益和影响力的工具.
发现25美元的经济激励措施在进一步增强超出提醒效果的助推器吸收方面是无效的.
公共卫生机构可以利用有针对性的消息传递策略来改善疫苗接种覆盖率,特别是在面临严重COVID-19结果风险较高的人群中.

关键词:

在 COVID-19 疫情中,助推器是一个助推器.实地实验是一种实地实验.推一推,推一个推.接种疫苗接种疫苗

The Placebo Effect

The Placebo Effect

The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Incentive Theory: Pull Theory of Motivation

Incentive Theory: Pull Theory of Motivation

Incentive theory, or the "pull theory" of motivation, suggests that external rewards primarily drive behavior. Individuals are motivated to engage in activities when they anticipate a desirable outcome. This is why people often work hard for promotions or study intensively to achieve high grades. These incentives can be tangible, physical rewards such as money or promotions, or intangible, non-physical rewards like praise and social recognition.

Persuasion Strategies

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Blinding

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Bystander Effect

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
