Dataset for: Results of a cluster-randomised controlled equivalence trial of the Surprise Soap hand washing intervention among older children living in a refugee settlement in Sudan

Increasing handwashing with soap (HWWS) among older children in emergency settings can have a large public health impact, however, evidence on what works is limited. One promising approach is the ‘Surprise Soap’ intervention in which a novel soap with an embedded toy is delivered to children in a short, participatory household session. This dataset contains the results of a cluster-randomised controlled equivalence trial to evaluate the Surprise Soap intervention against a standard intervention in a complex emergency setting.
