5 moments of hand hygiene explained11/28/2023 ![]() The knowledge-practice gap is more narrow for handwashing than for treatment of drinking water and sanitation. 6 In India, a handwashing awareness-raising campaign, the Great WASH Yatra, increased knowledge about the benefits of handwashing, but had little effect on changing intention to wash hands with soap. Improving handwashing knowledge alone is typically insufficient to change handwashing behavior. Find more information on the Handwashing Think Tank here. 5 This study was presented at the PPPHW’s 2016 Handwashing Think Tank. The proportion remained at 74% at 2 and 6 weeks post-completion follow-up visits. 5 An intervention study in two primary schools in rural Bangladesh showed that the proportion of handwashing after latrine use among students increased from 4% at baseline (no intervention), to 18% after adding handwashing infrastructure, then to 58% after adding the footpaths, and then to 68% after adding the footpath and handprints. Non-verbal environmental cues are effective at changing behavior without using traditional methods of behavior change communication. The probability of handwashing during the experiment was lowest in control (18%), followed by visual cues (40%), auditory cues (40%), and odor (73%). ![]() 4 An experiment on handwashing in a food service setting involved 80 Hispanic/Latino participants performing prospective memory while one of the four following handwashing cues was present: 1) disgusting image (visual cues) 2) disgusting sound (auditory cues) 3) disgusting odor (olfactory cues) 4) regular handwashing posters/controls. 1 Cuesĭisgust-based cues, particularly olfactory cues, were more effective at increasing handwashing behavior than conventional reminder posters. The cost for mass production of the Povu Poa system is estimated at $12 per unit, and can pay for itself in 1 year based on savings on the costs of water and soap. Povu Poa only used 357 mL of water and $0.10 of soap per wash, compared to 513 mL of water and $0.20 of soap per wash for conventional jug and basin with bar soap and 1429 mL of water and $0.47 of soap per wash for conventional sink and metal tap with bar soap. ![]() Researchers developed Povu Poa (“Cool Foam” in Swahili) that included a wooden frame, a rinse water container with water-frugal tap, a container of soapy water (a 50:1 water-to-powdered-soap mixture) with foaming soap dispenser (“soap foamer”), and a runoff collection bucket at the bottom of the frame. In Kenya, a new handwashing system was field-tested and found to improve water and soap efficiency. Behavior ChangeĮvidence increasingly demonstrates that cues and emotional drivers can impact handwashing behavior change.
