Social network analysis to evaluate nursing interventions to improve self-care.

Objective: To explore the impact of an educational intervention for self-care of elders on their knowledge of acute respiratory infections and its incidence within their social networks.

Method: The intervention was based on seven educational sessions with elders from Jiutepec (Morelos, Mexico) conducted between September 2009 and January 2010 in the context of the influenza A(H1N1) pandemic. Egocentric social network analysis was used to explore the transmission of knowledge within elders' networks.
