 The overall goals of this line of research are to develop and evaluate innovative treatments for lesbian, gay, bisexual, and transgender LGBT cigarette smokers and to understand the processes related to smoking and relapse in this previously unstudied population of smokers. In this study, participants are randomly assigned to one of two Internet-based smoking cessation treatments: 1 a self-help intervention tailored LGBT smokers plus social support plus email-based counseling, or 2 a standard self-help condition alone, similar to other general smoking cessation treatments. Before starting the program, participants will complete measures of smoking, nicotine dependence, depression diagnosis, demographics, mood, motivation to change, and alcohol use. Smoking status will be determined at 1, 3, 6, and 12 months following the start of treatment. Data will be analyzed to compare the quit rates of the two Internet-based treatment groups. Also, we will complete exploratory analyses to determine those variables that best predict quitting for LGBT smokers.
