Testing Financial Incentive Interventions in Dyadic-Smoker Couples

The proposed study investigates the feasibility and efficacy of FITs in dual-smoker couples [DSCs]. The core design is a three-group mixed repeated measures design, in which participants are randomized into one of three conditions (control [CTL], dyadic target [DT] FIT or single target [ST] FIT) and tracked across 3 months. During this time, participants will complete a baseline session and a follow-up. Between these visits, all participants will have access to a voluntary brief cessation program (i.e., online psychoeducation created for this study using Beat the Pack materials and resources from NCI, NIH + Nicotine Replacement Therapy [NRT]). The FIT involves monetary incentives for online psychoeducation completion and smoking abstinence at follow-up. In the ST condition, one member of each couple (i.e., the target) will receive monetary incentives; in the DT condition, both members of the couple will receive monetary incentives. This design allows for preliminary consideration of FITs in DSCs and tests whether FITs for both members of the dyad synergistically enhances outcomes.
