TRIAL DESCRIPTION
Public title Health and governance effects of a Randomized Control Trial of a Community-Driven Water, Sanitation, and Hygiene Program in the Democratic Republic of Congo
Official scientific title Health and governance effects of a Randomized Control Trial of a Community-Driven Water, Sanitation, and Hygiene Program in the Democratic Republic of Congo
Brief summary describing the background and objectives of the trial In 2008, the Government of the DRC launched a national program known as National Healthy Villages and Schools (in French Villages et Ecoles Assainis, VEA), a water and sanitation program financed by DFID and implemented by UNICEF and the Government of DRC’s Ministry of Public Health and Ministry of Primary, Secondary, and Professional Education. The VEA’s main objectives are to support communities’ improved access to water, hygiene, and sanitation services and practices through the construction of water and sanitation infrastructure in villages and schools, local community involvement, and a village certification mechanism. This study uses a cluster-level randomized controlled trial to evaluate the causal impact of the VEA program across 332 rural villages. Although VEA has been operational since 2008, the study focused on more recent activities; as the program was implemented in these villages in the later phase of the program (throughout 2019). It involves experimentally varying the provision of the VEA program to a set of villages to examine the causal impacts on water access, infrastructure development, availability of sanitation services, knowledge of hygiene practices, and child health. Two earlier papers assesses the short run effects of the program at approximately 5 months post-intervention and 12-24 months post-intervention (see pre-analysi plans at https://www.socialscienceregistry.org/trials/4648). We are now registering analysis plans for the 36-month follow-up.

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group The Health Villages and Healthy Schools Program Each village received the program once. Villages were grouped into clusters for randomization, to minimize spillovers. The group size below refers to the number of intervention clusters. The intervention ranged from 1 to 30 months. The median duration was 9 months. The intervention finances the construction of water and sanitation infrastructure in villages and schools and facilitates local community involvement in management of this infrastructure, with the view to fostering an environment in which household health and hygiene is managed by the communities themselves. It is based on the key concept of not just building infrastructure but also encouraging and mobilizing communities to become a “Healthy Village,” which they do by meeting or exceeding minimum standards for water, sanitation and hygiene. The VEA program is implemented in nine steps. 0. The community learns about the program and collectively decides to adopt it before submitting a formal request to the relevant Health Zone. 1. A statement of agreement between the community and the Health Zone is signed. 2. Health Zone officials investigate the behaviors, attitudes and practices of village households. 3. The community analyses its hygiene and sanitation using community mapping, undertakes observation walks, and analyses the three categories of classification for hygiene conditions as well as fecal-oral transmission routes. 4. he Health Zone provides training for 20 volunteers, then the community elects a village committee. 5.The community develops a Community Action Plan and prioritizes interventions. 6. NGOs contracted by UNICEF finance the construction of WASH infrastructure (water points, latrines) as identified by the community, and train the communities on infrastructure maintenance. In addition, the community takes additional actions to improve access to water and sanitation. Volunteers promote good hygiene practices. 7. The final investigation: the office of the Health Zone conducts a study of the community. 8. The chief medical officer of the Health Zone checks whether the village meets the standards required to be designated as a Healthy Village. 50

We aimed to interview all households that were targeted at 5-month follow up (four households per village), and an additional six, new, randomly-selected households in each village (n=332). That yields 1,328 households from 5-month follow-up and 1,992 new households, for a total of 3,320 households. We also aim to interview the village leader and water committee leader (if a water committee existed) in each village. In the event that they cannot be reached, replacements will be sought on a case by case basis. More details here: https://www.socialscienceregistry.org/trials/4648 Households that have lived in the village for less than four years will be excluded. 80 and over: 80+ Year,Adolescent: 13 Year-18 Year,Adult: 19 Year-44 Year,Aged: 65+ Year(s),Child: 6 Year-12 Year,Infant: 0 Month-23 Month,Infant: 1 Month-23 Month,Middle Aged: 45 Year(s)-64 Year(s),New born: 0 Day-1 Month,Preschool Child: 2 Year-5 Year 0 Year(s) 110 Year(s) Both
