At the same time, evidence on the effectiveness of at-scale behavior change interventions to improve sanitation and hygiene practices is limited.  \n\nIn response to the preventable threats posed by poor sanitation and hygiene, the World Bank's Water and Sanitation Program (WSP) has launched two large projects, Global Scaling Up Handwashing and Global Scaling Up Rural Sanitation, to improve the health and welfare outcomes for millions of people in developing nations.  These projects have been implemented by local and national governments with technical support from WSP. \n\nResearchers from the World Bank and Inter-American Development Bank studied these two projects impemented in rural Tanzania, with the objective of tracing the causal chain from hygiene and sanitation promotion to changes in child health outcomes. The research team specifically tested for potential interaction effects of combining handwashing and sanitation interventions. The study was designed as an effectiveness trial to provide evidence for policymakers and government implementing agencies planning at-scale campaigns.\n \nFrom mid-2009 to early 2011, two interventions were rolled out in ten districts  of Tanzania following a factorial experimental design. 181 rural wards included in the study were divided into four groups to receive the handwashing intervention alone, the sanitation intervention alone, both the handwashing and sanitation, or neither intervention (control group). \n\nA baseline was planned for early 2009 but was aborted due to logistical field challenges. Since random assignment of implementation was adhered to, the study continued and researchers conducted an endline survey in 2012, approximately one year after the conclusion of the program. The survey included 3,619 households and 5,768 children under five years old.","coll_dates":[{"start":"2012-05","end":"2012-11","cycle":"Endline"}],"nation":[{"name":"Tanzania","abbreviation":"TZA"}],"geog_coverage":"362 rural villages across 181 wards in 10 districts of Tanzania","analysis_unit":"individuals, households, villages","universe":"Households within selected treatment and control areas that had at least one child under 5 years old at the time of the endline survey in 2012","data_kind":"Sample survey data [ssd]","notes":"The scope of the study includes:\n\n- Household: demographics, latrine coverage and use, water coverage and use, handwashing practices and equipment, exposure to the intervention\n\n- Child: anemia, anthropometrics, health (diarrhea, ALRI)"},"method":{"data_collection":{"data_collectors":[{"name":"Economic Development Initiatives","abbreviation":"EDI","affiliation":""}],"sampling_procedure":"The ten selected intervention districts were  selected by the Ministry of Water (MoW) and Ministry of Health and Social Welfare (MoHSW). The districts were spread throughout the country to provide geographic diversity at the national level. These districts were not random, and were targeted because of operational feasibility for program implementation, taking into account the existence of ongoing MoW and MoHSW projects, including the Health Village Campaign (HVC) and water and sanitation interventions. \n\nOf 245 wards in these 10 districts, initially 13 wards were dropped from the sample. Three of these wards were urban, and thus ineligible for the program, and the remaining 10 wards were pre-selected as pilot areas for the program and excluded from the evaluation. Among the remaining 232 wards the program selected the 190 largest wards by population size in order to maximize the population under treatment.\n\nThe within-ward sampling procedure followed program operational guidelines targeting the two largest villages in each treatment ward, based on population size, in each of the 181 evaluation wards. For the 362 villages in the sample, the full list of census enumeration areas (EAs) was obtained from the Tanzanian National Bureau of Statistics (NBS). For each village, the sample included one EA, selected with probability proportional to size (PPS). A census listing exercise was then conducted in each EA to collect basic information to determine household eligibility for the survey. Survey eligibility criteria were (i) the household was present during the period of listing; (ii) had been living in the village since the beginning of 2009 or earlier; and (iii) had at least one child under the age of five. Ten eligible households were then selected from each EA at random for the sample.","coll_mode":"Computer Assisted Personal Interview [capi]","research_instrument":"The survey included household, community  and listing questionnaires.\n\nThe household survey included modules for the head of household as well as the primary caregiver of children under 5. \n\nAll surveys were done on the electronic platform SurveyBe.
