简要总结
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.

研究组 & 干预措施
QuitBet
QuitBet is a quit smoking game delivered via a smartphone application that lasts 28 days and includes contingency management in the form of a deposit contract, integrated exhaled breath carbon monoxide (CO) testing, a social feed on which "players" can post and respond to messages, and a "leaderboard" that displays players' status (i.e., whether they are still eligible to win). A game host will post educational information about smoking cessation and serve as a discussion moderator. Participants will deposit ("bet") $30 of their own money at the start of the game. Participants who submit a CO test that is 6ppm or lower (indicating no smoking) on at least 24 of the 26 days between day 3-28 will be declared winners and will split the pot of money that was deposited. All participants who submit at least 21 CO tests during the 28 day game, regardless of the CO test result, will be entered into a lottery to win a prize worth $75.

QuitBet-NS will NOT include the social feed, leaderboard, or any other social features.
