Smoking Cessation Through the Web: Latino Smokers Follow-Up Study
The primary goal of this project is to carry out a randomized controlled trial (RCT)
comparing quit rates of a Spanish/English stop smoking Web site to those of a no-intervention
or "quit on your own" control. The investigators have not included a no-intervention
condition in previous Web studies and although 20% of participants quit smoking at one year
are 20%, obtaining evidence that the investigators interventions yield higher abstinence
rates than a no-intervention control is the next logical step. Furthermore, although the
investigators Web site was designed in English and Spanish, the investigators success in
attracting the U.S. Hispanic/Latino (HL) population in either language has been limited, so
this project only will only conduct intensive telephone follow-up of HL smokers and add new
recruitment methods to do so.

this project only will only conduct intensive telephone follow-up of HL smokers and add new
recruitment methods to do so.
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.
