Despite recent efforts to expand reach of smoking cessation treatment options beyond clinic based care, smoking cessation treatment including the use of smoking cessation aids remain greatly underutilized. If cessation programs are to have significant impact (Impact = Reach X Efficacy) on changing health behavior at the population level, there is a fundamental need to develop new and innovative strategies to increase treatment intensity, access, and participation. The use of intensive behavioral therapies, such as contingency management (CM), have demonstrated efficacy for reducing smoking in difficult-to-treat populations, but have had limited reach given the need to verify abstinence multiple times daily via clinic based monitoring. The development of a mobile health (mHealth) platform to provide CM has made the use of intensive CM approaches portable and feasible. The primary goal of the current study is to evaluate the effectiveness of a proactive tele-health intervention that combines evidenced based treatment for smoking cessation with smart- phone based, portable contingency management on smoking rates. The central hypothesis is that increasing the intensity of available tele-health smoking approaches through the addition of mobile CM will be an effective way to reduce smoking rates in Veterans returning from the Iraq/Afghanistan wars. Guided by strong preliminary data, this hypothesis will be tested in a comparative effectiveness trial with a two-group design in which 260 Veteran smokers will be randomized to receive either a mCM intervention which combines evidenced based cognitive-behavioral telephone counseling (TC), a tele-medicine clinic for access to nicotine replacement (NRT), and mCM administered through a smart phone or to a control condition that will provide controls for therapist, medication, time and attention effects.
Specific aims are to evaluate (1) the impact of mCM on rates of abstinence from cigarettes as measured by bio-verified, self-reported prolonged abstinence at 3-month, 6-month, and 12 month post-randomization follow-up, (2) the relative cost-effectiveness of the mCM intervention in quality adjusted life years (QALY), and (3) potential treatment mediators including self-efficacy and treatment process mechanisms. The approach is innovative because it builds upon advances in mHealth technology and will be the first evaluation of smart phone based mobile CM in conjunction with other evidence- based smoking cessation treatment for OEF/OIF/OND Veterans. There is a surprising lack of research aimed at evaluating multi-component smoking cessation interventions that integrate CM with evidence-based cognitive-behavioral treatment and smoking cessation aids such as NRT. Cigarette smoking remains the most lethal substance use disorder in the United States and military veterans are at particular high risk for smoking related morbidity and mortality. The significance of identifying cost-effective approaches to decreasing tobacco use in the relatively young and at-risk cohort of returning Veterans could be tremendous as it will prevent significant morbidity and mortality.

Public Health Relevance

Veterans with recent military service are smoking at high rates and are at elevated risk for the development of smoking related illness. The current application builds upon advances in mHealth technology to increase reach of intensive smoking cessation treatment. It is expected that the addition of Mobile Contingency Management to evidence-based tele-health smoking cessation interventions will be a cost effective approach that will significantly reduce smoking among this at risk population.
