Improving Adherence to Web-based Cessation Programs: a Social Network Approach

Grant Summary:

Internet quit smoking programs can help smokers quit, but a challenge is getting would-be quitters to take advantage of all the available tools that are critical to quitting successfully. This study tested the impact of different strategies designed to boost engagement with an Internet quit smoking program (EX). More than 5,000 smokers were recruited at the time they registered on EX. All participants had full access to the tools and community on EX. In addition, some participants received personal welcome messages from existing community members, some received free quit smoking medication, and some received both. The study interventions boosted engagement in expected directions. However, the highest quit rates were achieved by participants who used all program elements without any study encouragement.
