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.

This study is comprised of 2 active phases, all conducted with registered users on
BecomeAnEX.org, a well-established smoking cessation website.
Phase I involves the initial development and optimization of the text message intervention.
The investigators will examine the impact of 4 experimental text message intervention
features on smokers' adherence to a web-based cessation intervention during the first 3
months of program enrollment. The investigators will utilize a full factorial design where
participants will be randomized to 1 of 2 levels of each of the following features: 1)
personalization (yes/no), 2) integration (yes/no), 3) dynamic tailoring (yes/no), and 4)
message intensity (standard vs. decreasing). The primary outcome in Phase I will be a
composite metric of utilization.
Phase II involves a 2-arm randomized trial that compares WEB alone to WEB plus the text
message intervention from Phase I that yields optimal adherence (WEB+OA_TXT). The randomized
trial will use a repeated measures design, with assessments at baseline, 3, 9, and 15 months.
Follow-ups at 3, 9, and 15 months correspond to 0, 6, and 12 months post-treatment. The
primary outcome is 30-day point prevalence abstinence (ppa) at 9-months. The investigators
will assess and validate smoking status at all follow-ups. Other outcomes include motivation
to quit, quit attempts, and continuous abstinence.
