QuitBet: A Digital Social Game that Pays You to Stop Smoking

项目总结/摘要 戒烟最有效的干预措施之一是应急管理（CM），其中 利用经济奖励来加强禁欲。然而，传统的基于临床的CM并不广泛 由于对可行性、可接受性和长期有效性的关注，数字 技术现在正在促进CM格式的出现，这些格式可能更可行，更可接受， 并有效促进长期禁欲。在此SBIR快速通道申请中，我们建议 完成开发并评估数字CM戒烟计划的有效性： 退出投注。QuitBet是模仿和建立在DietBet的商业成功，我们的第一个产品。所有 我们的产品，我们称之为游戏，结合联合收割机社会游戏元素与参与者资助的金融 存款合同形式的激励措施。我们的“玩家”存款（我们称之为他们的“赌注”）一个指定的金额 把自己的钱投到游戏的“底池”里。所有达到游戏目标的“赢家”平分底池， 使得他们投注被完全退还，加上他们从这样做的玩家的被没收的投注中获得额外的钱 没有达到目标。我们最近开发了QuitBet原型，并进行了初步的测试游戏， 玩家QuitBet的玩家交了30美元的存款。所有的球员都被邮寄了一个便携式，智能手机连接， 一氧化碳检测装置。QuitBet持续了28天，正式退出日期为第8天。从第9天到第28天（20天 期间），玩家每天从他们的30美元赌注中赚回1美元的CO验证禁欲。所有剩余赌注 钱被汇集到“大奖”的锅里。在20天中至少有19天禁欲的球员 被宣布为赢家并平分大奖。在QuitBet期间，玩家发布了CO测试 创建一个私人Facebook群组。他们还从一个游戏中接受了戒烟教育 与其他玩家互动。32名球员中有15名（47%）是赢家。玩家反馈是 非常积极。我们的第一阶段目标是实现以下里程碑：1）完成QuitBet的开发 智能手机应用程序，并进行试点试验（N = 50），以证明2）消费者的需求（即， （3）可接受性。我们的第二阶段目标是进行一项QuitBet与QuitBet-NS的随机试验 （仅存款合同，无社会要素）。所有参与者（N = 550）将在 他们的第一场比赛（长达8周的总比赛时间）。我们假设7天时点患病率 QuitBet中戒烟后1个月、3个月和6个月的戒烟率高于QuitBet-NS。我们将 还比较了QuitBet与QuitBet-NS在吸烟量和戒烟药物使用方面的差异， 研究结果的潜在中介因素，如动机，参与和满意度。

PROJECT SUMMARY/ABSTRACT One of the most effective interventions for smoking cessation is contingency management (CM), in which financial incentives are used to reinforce abstinence. However, traditional, clinic-based CM is not widely available because of concerns about feasibility, acceptability, and long-term effectiveness. Digital technology is now facilitating the emergence of CM formats that are likely to be more feasible, acceptable, and effective at promoting long-term abstinence. In this SBIR Fast Track application, we are proposing to complete development and evaluate the effectiveness of a digital CM program for smoking cessation: QuitBet. QuitBet is modeled upon and builds upon the commercial success of DietBet, our first product. All of our products, which we call games, combine social gaming elements with participant-funded financial incentives in the form of a deposit contract. Our “players” deposit (we call it their “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. We recently developed the QuitBet prototype and conducted an initial test game with 32 players. QuitBet players made a $30 deposit. All players were mailed a portable, smartphone-connected CO testing device. QuitBet lasted for 28 days, with the official quit date on day 8. From day 9-28 (a 20-day period), players earned back $1 of their $30 bet per day of CO-verified abstinence. All remaining bet money was pooled into the “grand prize” pot. Players who were abstinent on at least 19 of the 20 days were declared winners and split the grand prize pot equally. During QuitBet, players posted their CO test results in a private Facebook group. They also received education about smoking cessation from a game host and interacted with other players. Fifteen of the 32 players (47%) were winners. Player feedback was very positive. Our Phase I aim is to achieve the following milestones: 1) complete development of a QuitBet smartphone application and conduct a pilot trial (N = 50) to demonstrate 2) consumer demand (i.e., feasibility) and 3) acceptability. Our Phase II aim is to conduct a randomized trial of QuitBet vs QuitBet-NS (deposit contract only, no social elements). All participants (N = 550) will be offered a second game after their first game (up to 8 weeks total game duration). We hypothesize that 7-day point prevalence abstinence rates at 1, 3, and 6 months post-quit date will be higher in QuitBet than in QuitBet-NS. We will also compare QuitBet vs. QuitBet-NS on smoking heaviness and use of smoking cessation medication and examine potential mediators of outcomes such as motivation, engagement, and satisfaction.
