Cessation websites offer smokers convenience, low (or no) cost, and anonymity; however, there are no publicly available web-based cessation programs specifically designed for PLWH smokers. Smokers living with HIV have high rates of nicotine dependence, anxiety, depression, loneliness, and substance use. The investigators developed Positively Smoke Free on the Web (PSFW), a theory-driven, culturally tailored web-based program designed to address the specific needs of PLWH smokers. The investigators' NCI-funded R21 pilot of PSFW demonstrated moderate-high levels of adherence and yielded higher 3-month abstinence rates compared to standard care (10% vs. 4%). The investigators' prior research on web-based cessation interventions has shown that smokers who participate in an online community - whether passively reading posts by others or actively engaging in online discussions - are more than twice as likely to achieve abstinence even after controlling for a broad range of covariates. In preparation for the proposed study, the investigators' partners at Truth Initiative (formerly known as the American Legacy Foundation) have enhanced and modernized PSFW by integrating an online community platform (now "PSFW+"), developing a training protocol for PLWH smoker seed users (to provide a critical mass of social network participants), and recruiting and training 11 PLWH smokers for this role. The prototype PSFW+ application has been successfully alpha- and beta-tested in anticipation of the randomized controlled trial.
