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

Summary

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.

Conditions

• Smoking Cessation

Interventions

BEHAVIORAL

Personalization

Phase I Factor Personalized text messages using the participant's username and gender ("Check out the EX Community for tips/support from other men who have quit. They've been there and can help you do this, QuitForever!"). Both data points will be pulled from BecomeAnEX registration data.

BEHAVIORAL

Integration

Phase I Factor Interactive messages to facilitate engagement via text with the 6 interactive intervention components of the BecomeAnEX web intervention: Set your quit date Cigarette tracker Beat your smoking triggers Build your support system Choose a quit smoking aid Community Integration will allow interaction with the web-based program via text message; for example, when a user sets a quit date via the website, it will trigger text messages tailored to the quit date; likewise, if a user sets a quit date via the text system, it will be populated in the website and drive the user experience online.

BEHAVIORAL

Dynamic Tailoring

Individually tailored message to remind/reinforce users about BecomeAnEX information/tools they have already used, or to prompt users to take actions they have not yet taken.

BEHAVIORAL

Message Intensity

Phase I Factor Varying levels of text message intensity over a 12-week period.
