Smoking Cessation Through the Web: Latino Smokers Follow-Up Study

The main study will randomize participants to one of two conditions, an intervention
condition ("immediate") and a no-intervention control ("delayed"). For the control "quit on
your own" condition, we will offer a 6-month "Delayed" treatment condition (DC) and will
inform participants that we are testing whether smokers who are motivated enough to seek
Internet information on smoking cessation can quit on their own at the same rate as smokers
who are given access to an interactive stop smoking Web site. For our intervention, the
"Immediate" treatment condition (IC) is the UCSF Spanish/English Stop Smoking research Web
site (www.stopsmoking.ucsf.edu) that provides smokers their preference of all elements
tested in earlier trials: 1) a Web version of a National Cancer Institute-designated
evidence-based intervention with updated content, the Guía para Dejar de Fumar; 2) A
document summarizing pharmacological treatment to aide smoking cessation available over the
counter such as nicotine gum or patch or by prescriptions from a clinician; 3) e-mail
reminders to return to the site timed to individually set quit dates; 4) a mood management
smoking cessation intervention; and 5) a virtual group (an asynchronous bulletin board
designed to let participants provide mutual support). We will recruit study participants
until we have randomized 1200 HL smokers in English or Spanish stratified by gender within
language group. Participants will be followed at 1, 3, 6, and 12 months after randomization
to obtain self-reported prolonged abstinence and 7- and 30-day time point prevalence rates.
E-mail reminders will be sent to remind participants to return to the site to complete
follow-up surveys online. Only HL smokers from the US will be followed up by telephone calls
at 1 and 6 months. The main comparison measure will be cessation at 6 and 12 months from
original randomization. DC participants will be able to access the interactive site after
finishing the 6-month follow-up. We plan to attract Spanish-speaking HL participants to our
Web site using Spanish-language TV and radio interviews and public service announcements
(PSA), Spanish-language Google ads and networking with U.S. cessation groups.
