|Official Title:||Smoking Cessation Via Text Messaging: Feasibility Testing of SMS USA|
- Continuous Abstinence at 3-months Assessed in Accordance With the NIH Behavior Change Consortium's Recommendations [ Time Frame: 3-months post-quit ] [ Designated as safety issue: No ]
Continuous abstinence is defined as 5 or fewer cigarettes smoked since one's quit date. The question was asked based upon West et al., 2005: "Have you smoked at all, even just a puff, since [insert quit date]?" If yes, the respondent will be probed for how many cigarettes were smoked. Responses will be categorized into one of three options: A) No, not a puff; B) 1-5 cigarettes; C) More than 5 cigarettes.
Self-reported cessation is confirmed by a significant other.
- Point Prevalence [ Time Frame: 4-weeks post-quit ] [ Designated as safety issue: No ]A cigarette, even just a puff, within the last 7 days (yes/no).
- Continuous Abstinence at 4-weeks Post-quit [ Time Frame: 4 weeks post-quit ] [ Designated as safety issue: No ]Smoking five or fewer cigarettes since quit day at 4 weeks post-quit as verified by a significant other

Experimental: SMS USA
The 6-week smoking cessation intervention
Behavioral: SMS USA
Intervention participants receive text messages daily pre-and post-quit. Everyone receives messages 14 days prior to the Quit day, and through the day after Quit. Then, participants are 'pathed' to particular messages based upon their self-reported smoking status at Day 2 and Day 7 post quit, respectively. Those who are successful at quitting receive messages aimed at relapse prevention whereas those who have slipped receive messages aimed at getting the person to recommit to quitting and trying again.
Other Name: Stop My Smoking USA
No Intervention: Attention matched control
Messages aimed at improving one's sleep and increasing one's fitness, along with general messages about the most well known health dangers of smoking. Messages sent on the same schedule as the intervention group.
