Incentives for Oklahoma Tobacco Helpline Engagement in Persistent Poverty Counties

Phase 2

Completed

• Conditions: Cigarette Smoking; Nicotine Dependence
• Interventions: Behavioral: Coaching calls; Drug: Nicotine replacement therapy; Behavioral: Financial Incentives

• Registration Number: NCT05095779
• Lead Sponsor: University of Oklahoma

Brief Summary

The proposed pilot project is designed to evaluate the feasibility and potential efficacy of offering small financial incentives for the completion of smoking cessation counseling and self-reported abstinence at follow-up among Oklahoma Tobacco Helpline (OTH) callers living in persistent poverty counties (PPCs). The study will enroll at least 160 adults who reside in any of the 16 persistent poverty counties in Oklahoma, who are seeking smoking cessation treatment through the OTH.

Detailed Description

The proposed randomized controlled trial will enroll adults who are seeking smoking cessation treatment through the OTH and who reside in any of the 16 PPCs in Oklahoma. Participants will be randomly assigned to OTH (coaching calls + nicotine replacement therapy) or OTH plus escalating financial incentives (OTH+FI) for completing up to 5 counseling calls over 8 weeks. Feasibility outcomes for the incentives-based intervention will focus on counseling call completions, follow-up assessment completion, smoking cessation, and incentive costs. Potential effectiveness will be evaluated based on comparisons of counseling call completions over the first 8 weeks post-enrollment and rates of self-reported smoking abstinence through 12 weeks post-enrollment (4 weeks after incentives have ended) in OTH+FI relative to OTH alone.
