Opinion Leadership and Social Contagion in New Product Diffusion
There is evidence of contagion operating over network ties, even after controlling for marketing effort and arbitrary systemwide changes, and sociometric and self-reported measures of leadership are weakly correlated and associated with different kinds of adoption-related behaviors.
Network Interventions
In this Review, four strategies for network interventions are described, each of which has multiple tactical alternatives and can incorporate different mathematical algorithms.
Identifying Opinion Leaders to Promote Behavior Change
10 techniques used to identify opinion leaders to promote behavior change are reviewed and the advantages and disadvantages of the 10 methods are presented and sample instruments for each are provided.

This program was associated with improved knowledge and the psychosocial factors related to healthy eating and dietary fiber intake of students in a remote First Nations community and exposure to the intervention was not associated with dietary intent or the percentage of energy from dietary fat.
