Friendship Nomination is a cost-effective improvement that can easily be incorporated into a variety of programs based on findings from Social Network Analysis, but its effectiveness may be context specific. A recent paper by Kim, et. al., describes an experimental evaluation of several social network interventions for water purification and nutrition. While a very intensive whole-network-based approach shows no beneficial effect, a simple process called Friendship Nomination shows some promise for multivitamin uptake, though chlorine tablet uptake was unaffected. Here’s a little intro video describing Friendship Nomination from a presentation I did on the technical aspects of the paper to a public health audience with little background in Social Network Analysis.
