Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Contingency management, or a method of providing financial incentives contingent upon positive behaviors, has shown promise for improving adherence to medication among diabetics and for improving smoking cessation in other populations. This approach could offer an innovative and scalable means of increasing abstinence in this group, ultimately reducing their risk of cancer. This is a multicenter pilot randomized controlled trial that will recruit participants in Oklahoma and in Strathclyde, Scotland.
This pilot study aims to test the feasibility of providing incentives to patients with T2D contingent on remote biochemical verification using a smartphone carbon monoxide (CO) monitor. The investigators will use an ecological momentary assessment (EMA) smartphone application and CO sensor to monitor urges to smoke, stressors, smoking behaviors, and to validate continuous abstinence throughout the intervention. Two different contingency management structures will be explored to investigate the length of time incentives need to be offered. Qualitative semi-structured interviews will be used to explore the patient and provider acceptability of an incentive-based cessation program, any unintended consequences and possible differences between UK and US health settings.
The results of this research will inform the feasibility of carrying out a randomized controlled trial of this intervention. The ultimate aim is to develop an effective intervention that could be scaled to the T2D population at large, which reduces cancer risk and improves disease outcomes among a high-risk group.

Financial incentives
Treatment arm participants will receive financial incentives ($20 per week) contingent on biochemically verified smoking abstinence submitted once daily for the time period allocated.
Long term incentives
usual quit smoking treatment (counseling + medication) plus 12-weeks of payments for proof of smoking abstinence
Financial incentives
Treatment arm participants will receive financial incentives ($20 per week) contingent on biochemically verified smoking abstinence submitted once daily for the time period allocated.
No incentives
usual quit smoking treatment (counseling + medication)
