The primary purpose of the proposed project is to evaluate an automated smartphone-based CM approach that will allow socioeconomically disadvantaged adults to earn financial incentives for smoking cessation without requiring in-person attendance for abstinence verification. The investigators have combined technologies: 1) low-cost carbon monoxide monitors that connect with mobile phones17 to remotely verify smoking abstinence, 2) facial recognition software to verify the identity of participants while they provide a breath sample, and 3) remote and automated delivery of incentives to a credit card triggered by biochemical confirmation of self-reported smoking abstinence. This CM approach will be evaluated in a randomized controlled trial of 532 socioeconomically disadvantaged males and females seeking smoking cessation treatment. Participants will be randomly assigned to telephone counseling plus nicotine replacement therapy (standard care [SC]) or SC plus a 12-week smartphone-based financial incentives intervention (CM). Participants will be followed for 26 weeks after a scheduled quit attempt, which is 14 weeks after incentives have ended. Cost-effectiveness will be evaluated to inform policy and health care decisions. Potential CM treatment mechanisms, including self-efficacy, motivation, and treatment engagement will be identified to optimize future versions of the intervention. The specific aims are: 1) to evaluate the impact of an automated, mobile phone-based CM approach relative to SC on smoking cessation among socioeconomically disadvantaged adults, 2) to compare the cost-effectiveness of two smoking cessation interventions (CM vs. SC), and 3) to identify mobile CM treatment mechanisms such as motivation to quit, self-efficacy for quitting, and treatment engagement/adherence. The proposed study will evaluate an intervention approach that increases the reach of a potentially effective and cost-effective smoking cessation intervention for socioeconomically disadvantaged smokers.
