Employing interpersonal influence to promote multivitamin use.

Boster, Kotowski, Andrews, and Serota (2011 ) proposed that superdiffusers are well connected, persuasive, and a maven in a content area. They proposed that superdiffusers, if recruited, could promote the adoption of health practices. In this article a model of this process is presented, and an intervention designed to test the efficacy of this influence strategy is introduced. Specifically, superdiffusers were recruited to persuade their peers to take a daily multivitamin. Evidence was found consistent with the intervention's effectiveness.
