افزایش فرکانس دست و شستشوی مراقبت کننده های اولیه در هارا، زیمبابوه: یک آزمایش کنترل شده به صورت خوشه ای تصادفی با استفاده از نتایج رفتاری و میکروبی

The results provide strong evidence that the campaign successfully improved handwashing frequency and technique. It shows that the population-tailored design, based on social-cognitive theory, provides effective means for developing powerful interventions for handwashing behavior change. We did not find evidence that children acted as strong agents of handwashing behavior change. The fact that the microbial effectiveness of handwashing did not improve despite strong improvements in handwashing technique calls for critical evaluation of existing handwashing recommendations. The aim of future handwashing campaigns should be to promote both frequent and effective handwashing.
