Evaluating the Individual and Combined Effects of Hand Hygiene Promotion and Hardware Provision on Handwashing With Soap in Lusaka, Zambia

The goal of this study is to assess the individual and combined effects of hand hygiene behavioural promotion and handwashing hardware and supply provision on handwashing with soap behaviour at handwashing opportunities in households in peri-urban communities in Lusaka, Zambia. Households will be randomly allocated to one of the four groups: AB) Hand hygiene behavioural promotion + handwashing hardware and supply provision, A) handwashing hardware and supply provision only, B) hand hygiene behavioural promotion only or C) No intervention. Researchers will compare handwashing behaviour between the four groups to see which is most effective.

Eligibility is assessed at the household level. Inclusion Criteria: * At least one adult (aged 18 or older) who can consent to the study on behalf of all members of the household. * At least one child under the age of 5. Exclusion Criteria: * Already own a similar handwashing facility (e.g., sink, handwashing station). * Not permanent residents of the selected community and/or plans to leave the community within the next 3-6 months.
