Efficacy of a Smoking Cessation Program for Underserved Ethnic Minority Communities: Results of a Smoking Cessation Trial.

Using a participatory research approach, this study reports the efficacy of the Communities Engaged and Advocating for a Smoke-free Environment (CEASE)-4 intervention offered by the local peers. CEASE-4 is a theory-based tobacco-cessation intervention, tailored to the needs of underserved populations. 842 tobacco users self-selected into: a) self-help ( = 472), b) single-session class ( = 163), and c) four-session class ( = 207). While self-help group only received educational materials, curriculum for other arms was built on the social cognitive, motivational interviewing, and trans-theoretical- frameworks. Participants could also receive nicotine replacement therapy (NRT). Outcome was self-reported smoking cessation measured 12 weeks after completion of the intervention, validated by exhaled carbon monoxide (CO) test. Quit rate was statistically different across groups, with highest quit rate in four-session and lowest quit rate in self-help arm. Cessation rates at follow up (12 weeks after completion of the intervention) were 2.3% in the self-help arm, 6.1% in the single-session arm and 13.0% in the four-session arm. While theory-based smoking cessation services are effective for underserved populations, four-session curriculum might be superior to a single session program.
