At 6 month follow up, the number of cigarettes the participant reported smoking during the previous 7 days (survey respondents only). In the 6 month follow-up survey, participants were first asked "Have you smoked a cigarette, even just a puff, during the past 7 days?" (yes/no answer choice). Participants who answered "no" were counted as smoking 0 cigarettes in this analysis. Participants who answered "yes" were then asked to report how many cigarettes they smoked on each day during the past week (day 1 being this day last week, day 2, day 3, day 4, day 5, day 6, day 7 being yesterday).

This study is a randomized controlled trial (RCT) of QuitBet, a digital contingency management program for smoking cessation. QuitBet combines social gaming elements with participant-funded financial incentives in the form of a deposit contract. QuitBet "players" deposit (called the "bet") a specified amount of their own money into the game's "pot." All "winners" who achieve the game's goal split the pot equally, such that their bet is fully refunded plus they receive extra money from the forfeited bets of players who did not meet the goal. Participants (N = 550) will be randomly assigned to QuitBet or QuitBet-NS (deposit contract only, no social elements). All participants will be offered a second game after their first game (up to 8 weeks total game duration) and will be asked to complete a survey after each game and at 1 and 4 months after the end of the second game (3 and 6 months after the start of their first game). The study will compare QuitBet vs. QuitBet-NS on smoking behavior outcomes and examine potential mediators of outcomes such as motivation, engagement, and satisfaction.
