Randomized trial
Objectives. To determine the efficacy of providing online cessation intervention for college smokers.
Methods. This is a two-group randomized controlled trial. The intervention group received $10 weekly
incentives to visit an online college life magazine that provided personalized smoking cessation messages
and peer email support. Evaluation assessments occurred at baseline and 8, 20, and 30 weeks after
enrollment. The primary outcome is self-reported 30-day abstinence at week 30. Carbon monoxide (CO)
breath testing was performed for participants reporting 30-day abstinence at week 30.
Results. Five-hundred and seventeen college smokers at the University of Minnesota were enrolled via
internet health screening (control=260, intervention=257) in the fall of 2004. Intervention participants
completed an average of 18.9 (SD 2.5) of 20 weekly website visits over the course of the study. The rate of 30-day
abstinence at week 30 was higher for the intervention compared to the control group (41% vs. 23%, p b 0.001). CO
testing showed low rates of under-reporting. There was no difference in self-reported 6-month prolonged
abstinence measured at week 30.
Conclusion. Providing personalized smoking cessation messages as part of a general interest online college life
magazine increased 30-day abstinence by the end of this two semester intervention.

Introduction
Young adulthood is a critical transition period in cigarette use over
the life course. Among adolescents who experiment with cigarettes,
the young adult years are often associated with an escalation in cig-
arette consumption and the establishment of regular smoking (Kandel
and Chen, 1995; Chassin et al., 1996; Orlando et al., 2004). Several
studies have also raised concerns regarding increased initiation of
smoking among young adults (Wechsler et al., 1998; Rigotti et al.,
2000; Husten, 2007). In a recent study, Tercyak et al. found that 25% of
individuals who reported never smoking in high school had initiated
smoking by 1 year later (Tercyak et al., 2007).
Encouraging cessation among young adults is a national health
priority. Smokers who quit before the age of 30 avoid much of the harm
related to cigarette use (Doll et al., 2004). Unfortunately, smokers
under this age appear to be less likely to quit compared to older
smokers (Lee et al., 2007). Recent work by Curry et al. offers some
explanation for this finding (Curry et al., 2007). While young adult
smokers are more likely to make attempts to quit compared to older
smokers, they are less likely to use effective assistance when doing so.
Studies of cessation programs designed for young adults have shown
mixed results. Quinlan and McCaul found no benefit to providing
stage-matched manuals to college smokers (Quinlan and McCaul,
2000). Ames et al. found no benefit to an expressive writing inter-
vention (Ames et al., 2005). Travis and Lawrence found that providing
stage tailored booklets increased abstinence at 3 months (Travis and
Lawrance, 2004). Prokhorov et al. found that providing computerized
feedback on “lung age” showed a marginal trend toward increased quit
rates (Prokhorov et al., 2003). In a sub-analysis, Rabius et al. found
an increase in short-term abstinence among young adult smokers
receiving phone counseling (Rabius et al., 2004). Additional work is
clearly needed to develop attractive and effective programs to help
young people to quit smoking.
The internet is a promising channel to improve delivery of smoking
cessation services to young adults. A growing body of literature
