Optimizing Text Messaging to Improve Adherence to Web-Based Cessation Treatment

This study is comprised of 2 phases to study the impact of a text message system on overall adherence to a web-based smoking cessation program. Phase I uses a full factorial design to identify the most optimal text message intervention to maximize adherence to the BecomeAnEX.org smoking cessation program. Phase II is a randomized controlled trial that compares regular BecomeAnEX users to those who will receive the optimized text message intervention (from Phase I) in conjunction with BecomeAnEX for impact on long-term abstinence.
