Peer-Facilitated Tobacco Cessation in a Prison Setting: A Proof of Concept Study.

Background: Despite the vast human and economic costs associated with tobacco use among U.S. inmates, smoking remains a largely ignored public health epidemic. Incarcerated individuals smoke at 3 to 4 times the rate of the general population and face tobacco-related health disparities.

Purpose: This paper reports results from a single arm, pre/post pilot study designed to test the feasibility and initial effectiveness of an inmate-administered group tobacco cessation intervention within a men's pre-release program run by the Arizona Department of Corrections.

Methods: Corrections staff and inmate peer mentors were trained in the DIMENSIONS: Tobacco Free Program, a manualized 6-session tobacco cessation group curriculum. Group sessions used evidence-based interventions for assisting inmates develop skills to live tobacco and nicotine free. In 2019-2020, 39 men who reported tobacco use voluntarily participated in one of three cessation groups. Wilcoxen signed-rank tests evaluated changes across group sessions in frequency of tobacco use and attitudes about nicotine-free living post release.

Results: Most participants attended all six group sessions (79%) and made one or more quit attempts (78%). Overall, 24% of the sample reported quitting tobacco, and significant reductions in tobacco use were reported after only two sessions. Participants further reported significant positive changes in knowledge, plans, support, and confidence to live tobacco-free lives post-release.

Conclusions: To our knowledge, this is the first study to demonstrate that, with minimal investment, implementation of an evidence-based, peer-led tobacco free program is feasible and effective within an incarcerated population uniquely vulnerable to the burden of tobacco.
