About this study
Official title: 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.
Read the detailed description
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
