Study of the Diffusion of a Smoking Cessation Application Through an Online Network - Full Text View

Purpose

Effective evidence-based interventions exist for smoking cessation delivered over the Internet, but consumer acceptance and adherence remains low. Scalable and efficient mechanisms to disseminate these interventions online are needed, and existing online social networks provide a potential mechanism. This is a proposal for a randomized, factorial trial of the dissemination of an evidence-based intervention through the massive Facebook social network, with the goal of determining intervention characteristics that drive viral spread.

Primary Outcome Measures:

Reproductive rate [ Time Frame: 30 days ] [ Designated as safety issue: No ]
The investigators will measure the reproductive rate for each condition, in other words the average number of additional individuals that install the application for each original individual recruited to participate. Higher reproductive rates indicate more efficient and faster dissemination.
