Summary

The current study will conduct an RCT to evaluate the effectiveness of a family-based incentive intervention with Alaska Native/American Indian families. The experimental arm will be compared to a control arm on biochemically-confirmed smoking abstinence at 6- and 12-months post-intervention.

Detailed description

Dyads will be stratified by the index participant's sex, and residence with family member, and by the family member's current smoking status then randomized to a no incentives control condition (n=328 dyads) or a 6-month incentive intervention (n=328 dyads). All dyads will receive existing evidence-based cessation materials on treatment resources and social support strategies. The study will measure the index participant's smoking status in both study groups weekly during the first four weeks, and at three and six months. All participants, including support persons, will receive incentives when they complete each of the smoking status assessments. The intervention group will additionally receive individual rewards provided to the index participant for achieving verified smoking abstinence at each time point, to a maximum of $750. The enrolled family member will also receive rewards equivalent to the value earned by the index participant that can contribute to family needs. The study will explore potential moderators (e.g., family member smoking status, index participant's sex) and mediators (e.g., interdependence) of intervention effects.
