This final report of the DEMO-CLTS project funded by the Bill and Melinda Gates Foundation aimed to assess the impact of CLTS on OD, both in its entirety and individually for its key elements; moreover, it aimed to determine the mechanisms of CLTS for behavioral change. The study also compared the effectiveness of the CLTS approach against that of an evidence-based approach.

The project’s overall goal was to improve the behavioral change strategies used to eliminate OD.

In a first phase of the project taking place in Mozambique, Lao PDR and Cambodia elements of the broad CLTS canon fostering or constraining the success of CLTS was identified. In a second phase in Ghana a randomized controlled trial was conducted, mainly to address the following objectives:
- Assessment of the effectiveness of CLTS interventions on Open Defecation
- Determination of the impact of CLTS as entirety and of its key elements on behavior change
- Comparison of CLTS with an evidence-based behavior change intervention targeting psychological factors determined by a baseline survey
