We are committed to providing programing that is research-based and rigorously evaluated. We are very proud to partner with the University of Denver for all project evaluation. Specifically we work with Dr. Renee Bottà who brings over 20 years experience in behavior-change communication research and evaluation; she has worked in the Kibera community since 2009.

The Power of Soap Program is evaluated in a number of ways.

Community-Level Surveys

In 2014, three systematic random sample surveys were collected. This data will be used to evaluate overall changes in community knowledge, attitudes, perceptions and behaviors regarding family health, handwashing, diarrhea, and purchasing Power Soap.

  • February 2014, prior to the launch of Phase I
  • September 2014, prior to the launch of Phase II
  • November 2014, eight weeks into Phase II

Handwashing Intervention Research Study

An eight-week study was conducted to assess the impact of the handwashing intervention. A manuscript titled, Using Micro-Enterprises as a Health Communication Platform to Promote Handwashing with Soap in Sub-Saharan Africa (Botta, R., Fenson-Hood, K., Grable, N.), was submitted to the Journal of Health Communication International Perspectives in Summer 2015.

  • Pre and post quantitative surveys were collected with Power Soap clients.
  • Weekly seller reports were also collected. Reports detailed progression for each client through the stages of change and any barriers identified in the discussion.

Business Model Evaluation

  • An analysis of 2014 sales was conducted.
  • An analysis of various incentive models will take place in 2015.
  • The in-country financial model was also analyzed.
