Abstract：
Contagious diseases that affect young children place a great burden on them and their families. Proper hand hygiene is an important measure to reduce the disease burden, however, its implementation in day care centres is challenging. This paper introduces a digital intervention to support independent and good handwashing among young children. The intervention leverages animated instructions triggered by water and soap use, together with a symbolic reward shown to children on a screen during and immediately after handwashing. We tested the intervention in a pre-registered, cluster-randomised controlled field trial in 4 day care centres in Finland and Germany with 162 children over 42 days. The intervention increased soaping time, used as a proxy for handwashing quality, by 5.30 s (+ 62%, p < 0.001). The effect occurs immediately at the onset of the intervention and is maintained throughout the intervention phase.
摘要：
影响幼儿的传染病给他们和他们的家庭带来了巨大的负担。正确的手卫生是减轻疾病负担的重要措施,然而,它在日托中心的实施具有挑战性。本文介绍了一种数字干预措施，以支持幼儿独立和良好的洗手。该干预措施利用了水和肥皂使用引发的动画指令，连同在洗手期间和之后立即在屏幕上向儿童显示的象征性奖励。我们在预先登记的情况下测试了干预措施，在芬兰和德国的4个日托中心进行的集群随机对照现场试验,纳入162名42天以上的儿童.干预增加了皂洗时间，用作洗手质量的代表，到5.30秒(+62%，p<0.001)。效果在干预开始时立即发生，并在整个干预阶段保持不变。
