Testing Financial Incentive Interventions in Dyadic-Smoker Couples

Not Applicable

Completed

Brief Summary: 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. The FIT involves monetary incentives for online psychoeducation completion and smoking abstinence at follow-up.

Detailed Description: 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.

Arm && Interventions

Group	Intervention	Description
Single Target (ST)	Financial Incentives	One member of each dyadic-smoking couple will receive financial incentive intervention

Primary Outcome Measures

Name	Time	Method
Smoking Abstinence	Follow-up study session 3 months post-baseline session	Percentage of targets who have quit smoking by the follow-up study cessation verified biochemically
Feasibility of Financial Incentives Treatment in Dyadic-Smoker Couples	Through study recruitment and study completion, an average of five months	Feasibility of financial incentives treatment in dyadic-smoker couples was assessed by number of individuals retained in study. Retention was separated by condition.
Tolerability of Financial Incentives Treatment in Dyadic-Smoker Couples	Through study recruitment and study completion, an average of five months	Participant subjective ratings of the benefits and costs of participating in the study. Tolerability was defined using eight items assessing the accessibility, benefits, and costs of the study scored on a 1 (strongly disagree) to 7 (strongly agree) scale. Tolerability scores were separated by target and partner and reported by condition.
