This double-blind field study tested the effectiveness of a baby-eyes image in promoting healthcare workers’ hand-hygiene compliance in a hospital setting. Adults are inclined to take care of babies and aspire to be their role models; therefore, they should wash their hands thoroughly when being watched by babies. Participants were healthcare workers from the obstetrical and neonatology units of a women’s hospital in Hangzhou. We recorded and coded 3,360 hours and 10,325 hand-hygiene events over a five-week period—from 16 October to 20 November 2018. Three types of stickers, depicting baby eyes, adult eyes, or flowers, were placed above handwashing basins to compare hand-hygiene behavior between the three conditions. Each condition continued for one week, and experimenters interchanged the stickers in each unit to control for the location and sequence effects. Participants in the baby-eyes condition (72.9%) were more likely to use sanitizer than those in the flowers condition (69.4%; χ² = 9.74, p < .01, φ_c = 0.034). Moreover, participants in the baby-eyes condition were more likely to use sanitizer than those in the adult-eyes condition (70.8%); however, the difference only trended towards significance (χ² = 2.38, p = .066, φ_c = 0.023). The mean handwashing time between the three conditions was significant (Welch’s F(2, 3488.436) = 3.50, p < .05, η² = 0.001). Washing time in the baby-eyes condition (17.41 ± 12.02) was significantly longer than in the adult-eyes condition (16.36 ± 11.47; p < .05). The presence of a baby-eyes image promoted hand-hygiene compliance in the hospital environment. This finding can be adopted to change public health behaviors. It also holds theoretical implications that enhance our understanding of how being monitored by children can enhance responsible behaviors.

这项双盲实地研究测试了婴儿眼睛图像在促进医院环境中医护人员手部卫生依从性方面的有效性。成年人倾向于照顾婴儿并渴望成为他们的榜样；因此，在被婴儿看管时，应彻底洗手。参与者是杭州一家妇科医院产科和新生儿科的医护人员。我们在 2018 年 10 月 16 日至 11 月 20 日的五周内记录并编码了 3,360 小时和 10,325 次手部卫生事件。三种类型的贴纸，描绘婴儿眼睛、成人眼睛或花朵，被放置在洗手盆上方以比较手- 三个条件之间的卫生行为。每个条件持续一周，实验者在每个单元中互换贴纸以控制位置和序列效果。婴儿眼睛状态的参与者（72.9%）比鲜花状态的参与者（69.4%；χ ²  = 9.74，p  < .01，φ _c  = 0.034）。此外，婴儿眼睛状况的参与者比成人眼睛状况的参与者更可能使用消毒剂（70.8%）；然而，差异仅趋于显着性（χ ²  = 2.38，p  = .066，φ _c  = 0.023）。三种条件之间的平均洗手时间是显着的（Welch's F (2, 3488.436) = 3.50, p  < .05, η ²  = 0.001）。婴儿眼睛条件下的洗涤时间 (17.41 ± 12.02) 明显长于成人眼睛条件下 (16.36 ± 11.47; p < .05)。婴儿眼睛图像的存在促进了医院环境中手部卫生的依从性。这一发现可用于改变公共卫生行为。它还具有理论意义，可以增强我们对儿童监控如何增强负责任行为的理解。
