我们评估了一个现场实验的结果，旨在衡量的效果提示，形成实现的行为结果的实施意图。感兴趣的结果是，一家大公司向其员工提供免费的现场诊所流感疫苗接种收据。所有有资格参加研究的员工都收到了提醒邮件，其中列出了相关疫苗接种诊所的时间和地点。向随机分配至治疗条件的员工发送的邮件还包括提示，要求写下（i）员工计划接种疫苗的日期或（ii）员工计划接种疫苗的日期和时间。当这些执行意向提示被包含在邮件中时，疫苗接种率增加了。对照组职工疫苗接种率为33.1%。那些被提示只写下一个日期的员工的疫苗接种率比对照组高出1.5个百分点，这一差异在统计学上并不显著。那些收到更具体的提示，要求写下日期和时间的员工的疫苗接种率高出4.2个百分点，这一差异在统计学上是显著的，也是有意义的。
We evaluate the results of a field experiment designed to measure the effect of prompts to form implementation intentions on realized behavioral outcomes. The outcome of interest is influenza vaccination receipt at free on-site clinics offered by a large firm to its employees. All employees eligible for study participation received reminder mailings that listed the times and locations of the relevant vaccination clinics. Mailings to employees randomly assigned to the treatment conditions additionally included a prompt to write down either (i) the date the employee planned to be vaccinated or (ii) the date and time the employee planned to be vaccinated. Vaccination rates increased when these implementation intentions prompts were included in the mailing. The vaccination rate among control condition employees was 33.1%. Employees who received the prompt to write down just a date had a vaccination rate 1.5 percentage points higher than the control group, a difference that is not statistically significant. Employees who received the more specific prompt to write down both a date and a time had a 4.2 percentage point higher vaccination rate, a difference that is both statistically significant and of meaningful magnitude.
