Randomized Controlled Trial of Dyadic Financial Incentive Treatment for Dual Smoker Couples: Evaluation of Efficacy, Mechanisms, and Cost Effectiveness

Abstract Dual-smoker couples (i.e., both members of a dyad smoke) are prevalent and treatment-resistant; they also confront unique challenges that may reduce the impact of treatment as usual for them. The proposed research systematically examines the efficacy, mechanisms, and cost effectiveness of mechanisms of implementing financial incentive treatments in this population and compares them to a no-incentive control on abstinence at end of treatment. Support for the efficacy of dyadic financial incentive treatments for dual-smoker couples would be a scalable intervention for implementation at the population level.
