Summary
Smoking cessation services are an unmet need among the homeless, who smoke at rates more
than 3 times the national estimate; successful interventions in this underserved population
have the potential for improving individual and public health. Contingency management (CM)
is a behavioral intervention with efficacy in a number of substance use disorder
populations, including smokers. However, no known studies have evaluated the effect of CM in
homeless smokers. The investigators plan to examine smoking-related outcomes in homeless
treatment-seeking smokers (N = 70) randomized to standard care smoking cessation
(transdermal nicotine replacement therapy [NRT] + standard counseling + carbon monoxide [CO]
monitoring) or standard care plus CM (NRT + standard counseling + CO monitoring + CM)
conditions. Standard counseling and CO monitoring will occur for the first 4 weeks, with NRT
use continuing through week 8. Participants in both conditions will meet with study staff up
to twice daily on weekdays for biochemical verification of smoking status. Participants in
the CM condition will have the opportunity to earn prizes for negative breath samples (CO ≤
4 ppm) up to twice daily on weekdays. CO breath samples will be collected at all visits. The
investigators expect that participants randomized to CM will have better outcomes compared
to those in standard care.
