Smoking prevalence in homeless populations is strikingly high (~ 70%), yet little is known about effective smoking cessation interventions for this population.We conducted a community-based clinical trial, Power To Quit (PTQ), to assess the effects of motivational interviewing (MI) and nicotine patch (NRT) on smoking cessation among homeless smokers.This paper describes the smoking characteristics and co-morbidities of smokers in the study.430 homeless adult smokers were randomized to either the intervention arm (NRT+MI) or to the control arm (NRT+Brief Advice).Baseline assessment included demographic information, shelter status, smoking history, motivation to quit smoking, alcohol/other substance abuse, and psychiatric co-morbidities.Of the 849 individuals who completed the eligibility survey, 578 (68.1%) were eligible and 430 (74.4% of eligibles) were enrolled.Participants were predominantly African American, male, had mean age of 44.4 (S.D=9.9), and the majority were unemployed (90.5%).Most participants reported sleeping in emergency shelters;nearly half had been homeless for more than a year.Nearly all of the participants were daily smokers who smoked an average of 20 cigarettes per day.Nearly 40% had PHQ-9 depression scores in the moderate or worse range and more than 80% screened positive for lifetime history of drug abuse or dependence.This study demonstrates the feasibility of enrolling a diverse sample of homeless smokers into a smoking cessation clinical trial.The uniqueness of the study sample enables investigators to examine the influence of nicotine dependence as well as psychiatric and substance abuse co-morbidities on smoking cessation outcomes..
