STUDY SUMMARY 
 
Study Title 
Enhancing Smoking Cessation in the Homeless 
Population 
Study Design 
The goal of this study is to enhance smoking 
cessation rates for homeless smokers by testing 
effects of 1) an Intensive Smoking Intervention, and 
2) integrating alcohol abuse treatment with smoking 
cessation. We initially utilized a 3-group 
randomized design to test study hypotheses. The 
three study conditions were: 1) Integrated Intensive 
Smoking plus Alcohol intervention using cognitive 
behavioral therapy, CBT—(IS+A); 2) Intensive 
Smoking Intervention using CBT—(IS); or 3) Usual 
Care (brief smoking cessation and brief alcohol 
counseling both based on the USPHS’s 
Guidelines)—(UC). The addition of the alcohol use 
criteria resulted in nearly two-thirds of those 
screened to be deemed ineligible. Consequently the 
study was revised to eliminate the Intensive 
Smoking Intervention using CBT—(IS) arm and the 
study period reduced from 52 weeks to 26 weeks to 
improve enrollment into the intensive smoking and 
alcohol and usual care arms. All participants receive 
12-week of treatment with the nicotine patch plus 
nicotine gum/lozenge. Counseling follows the 
protocol used in a recent study of alcohol dependent 
smokers and includes weekly individual sessions for 
3 months. Both study conditions will have equal 
number of study contacts. Study staff make 
retention contacts with participants in the 
community during weeks that do not have study 
visits scheduled. Primary smoking outcome is 
cotinine-verified 7-day smoking abstinence at week 
26 follow-up while secondary outcome is prolonged 
smoking abstinence at weeks 12 and 26. Secondary 
alcohol outcome will be self-reported continuous 
alcohol abstinence for 90 days at week 26. 
Recruitment and retention will be enhanced by use 
of gift cards, bus passes, and other non-monetary 
incentives. Participants will be enrolled from 
homeless shelters and facilities in the 7-county 
greater Minneapolis/St. Paul metro area. 
Primary Objective 
Hypothesis 1: At 26 weeks post randomization, 
homeless smokers who receive Integrated Smoking

plus Alcohol Intervention (IS+A) will have 
significantly better biochemically-verified 7-day 
abstinence rate from cigarette smoking compared to 
those who received Usual Care (UC). 
Hypothesis 2: At 26 weeks post randomization, 
homeless smokers who receive Integrated Smoking 
plus Alcohol intervention (IS+A) will have 
significantly better 90-day abstinence rate from 
alcohol consumption compared to smokers who 
receive Usual Care (UC). 
Exploratory Aim 
Hypothesis 3: At 26 weeks post randomization, 
homeless smokers who receive Intensive Smoking 
Intervention (IS) will have significantly higher 
biochemically-verified 7-day abstinence rate from 
cigarette smoking compared to those who receive 
Usual Care (UC). 
Secondary Objective(s) 
1. To evaluate how smoking cessation or reduction 
relate to psychosocial factors such as levels of 
depression, hopelessness, and perceived stress at 
weeks 12 and 26 follow-up 
2. To evaluate how alcohol abstinence or reduction 
relate to psychosocial factors such as levels of 
depression, hopelessness, and perceived stress at 12 
and 26 weeks follow-up. 
3. To evaluate how treatment outcomes relate to 
history of other substance abuse 
4. To evaluate, how treatment outcomes relate to 
opportunities for employment and housing, as well 
as overall health and well-being. 
5. To evaluate participants' perceptions of the 
acceptability and usefulness of components of the 
various interventions

Objectives 
1.1 Purpose:  
Although the overall prevalence of smoking in the United Sates has 
declined, rates remain strikingly high (70%) in homeless 
populations. A majority of homeless smokers also abuse alcohol and 
other drugs which makes quitting more difficult and heightens the 
health consequences of tobacco use. However, most smoking 
cessation research has excluded this most vulnerable segment of our 
population. Over the past several years, our research team conducted 
studies aimed at reducing tobacco use in homeless populations. The 
first National Institute of Health (NIH)-funded (R01HL081522; 
Okuyemi, Pl) smoking cessation clinical trial (n=430) targeted 
homeless smokers with 8-week treatment with nicotine patch and 6 
sessions of motivational interviewing (Ml). This relatively low 
intensity study showed cotinine-verified 7-day quit rates of 9.3% for 
Ml vs. 5.6% for Brief Advice at 26 weeks. We also found that 
quitting smoking was associated with reduced alcohol use. These 
smoking quit rates are low compared to the general population, 
demonstrating the challenge for tobacco interventions in this 
population and the need for more research. The goal of this study is 
to evaluate interventions designed to enhance smoking cessation 
rates for homeless smokers by testing the effects of 1) intensive 
smoking intervention (i.e. higher dose and duration than our previous 
R01), and 2) integrating alcohol abuse treatment with smoking 
cessation. We utilize a 2-group randomized design to test study 
hypotheses. The study conditions are: 1) Integrated Intensive 
Smoking intervention using cognitive behavioral therapy (CBT) plus 
Alcohol intervention -(IS+A) and, 2) Usual Care (brief smoking 
cessation and brief alcohol counseling both based on the US Public 
Health Service's Guidelines). In addition, all participants receive 12-
weeks of treatment with a combination of nicotine patch plus gum or 
lozenge. 
2.0 
Background 
2.1 Significance of Research Question/Purpose:  
Despite strikingly high rates of tobacco use in homeless populations, there is 
limited empirical data about how to help homeless smokers quit smoking. 
Because quit rates are low in homeless populations it is critical to develop 
more powerful interventions for improving cessation rates. Given that the 
majority of homeless smokers also abuse alcohol, a logical next step to 
improve smoking cessation rates in this group is to address their alcohol 
abuse along with a more intensive pharmacological and behavioral smoking 
cessation intervention.

2.3 This study is a follow-up study to the initial study, Power to Quit (PTQ) that 
used a similar study design. An association was noted between smoking 
cessation/reduction and alcohol cessation/reduction. We conducted a 
secondary analysis to examine the association between smoking cessation 
and substance abuse in the PTQ study. Participants with verified abstinence 
at week 26 had greater reduction in alcohol drinking days compared to 
participants who did not quit smoking (-3.8 vs. -0.8; p=0.05). We also 
examined the quit rates at 26 weeks by alcohol use status at 8 weeks among 
the subset that reported drinking alcohol on one or more days at baseline 
enrollment. Alcohol drinkers at baseline who reported quitting alcohol at 8 
weeks follow-up had higher smoking abstinence rate (10.1%) at week 26 
follow-up compared with those remained drinkers.

longitudinal outcomes for the CO-verified abstinence at weeks 1, 2, 
4, 6, 8 and 26 including time and intervention group as predictors.

Addictive Behaviors.  This paper described the recruitment and eligibility of 
homeless smokers who participated in the PTQ study. Working with local 
shelters, a total of 847 adult smokers were screened for study eligibility of 
which 580 (68.5%) met eligibility criteria.  Of those eligible, 430 (74.1%) 
returned for randomization. Eligible participants who returned for 
randomization were older and more likely to have a phone number 
compared to eligible participants who were not enrolled in the study.  
Knowledge of these factors including inclusion and exclusion criteria may 
help researchers tailor criteria that accurately identify and include homeless 
smokers in future clinical trials.

Study Intervention(s)/Investigational Agent(s) 
4.1 Description:  
The study is a 2-group randomized design to test study hypotheses. The two 
study conditions are 1) Integrated Intensive Smoking plus Alcohol 
intervention using cognitive behavioral therapy, CBT—(IS+A); 2) Usual 
Care (brief smoking cessation and brief alcohol counseling both based on 
the USPHS’s Guidelines)—(UC). All participants receive 12-weeks of 
treatment with a nicotine patch plus nicotine gum/lozenge. Counseling 
follows the protocol used in a recent study of alcohol dependent smokers 
and includes weekly individual sessions for 3 months. All study participants 
complete weekly study surveys during the first 12 weeks and at weeks 14, 
16, 18, 22 and 26. Both study conditions have equal number of study 
contacts. Study staff make retention contacts with participants in the 
community during weeks that do not have study visits scheduled. Primary 
smoking outcome is cotinine-verified 7-day smoking abstinence at week 26 
follow-up while secondary outcome is prolonged smoking abstinence at 
weeks 12 and 26. Secondary alcohol outcome is self-reported continuous 
alcohol abstinence for 90 days at week 26. Recruitment and retention are 
enhanced by use of gift cards, bus passes, weekly raffles, and other non-
monetary incentives. Participants are enrolled from homeless shelters and 
facilities in the 7-county greater Minneapolis/St. Paul metro area.

Smoking plus Alcohol intervention using cognitive behavioral therapy, 
CBT—(IS+A) or 2) Usual Care (brief smoking cessation and brief alcohol 
counseling both based on the United States Public Health Service’s 
Guidelines)—(UC). All participants receive 12 weeks of treatment with 
nicotine patches plus nicotine gum or lozenges. Participants randomized to 
the counseling arm receive cognitive behavioral therapy for tailored for 
smoking cessation and for alcohol cessation. Both study conditions have 
equal number of study contacts. Participants are scheduled for weekly visits 
during the first 12 weeks of the study and also at weeks 14, 16, 18, 22, and 
26. Study staff make retention contacts with participants in the community 
during weeks that do not have study visits scheduled. Primary smoking 
outcome is cotinine-verified 7-day smoking abstinence at week 26 follow-
up while secondary outcome is prolonged smoking abstinence at weeks 12 
and 26. Secondary alcohol outcome is self-reported continuous alcohol 
abstinence for 90 days at week 26. Recruitment and retention are enhanced 
by use of gift cards, weekly raffles, bus passes, and other non-monetary 
incentives. Participants are enrolled from homeless shelters and facilities in 
the 7-county greater Minneapolis/St. Paul metro area. 
 
5.2 Study Procedures:  
Participants are recruited at Twin City area homeless shelters and service 
organizations serving homeless adults to complete an eligibility survey to 
determine if they meet the eligibility requirements of the study. Eligible 
participants are scheduled for the baseline enrollment visit at which time 
study staff explain the study in detail, obtain consent, administer a baseline 
date collection survey and randomize the participant to one of the two study 
arms. Participants are scheduled for weekly data collection surveys and 
counseling sessions for those randomized to the counseling arm for the first 
12 weeks of the study and every other week (14, 16 and 18) and at weeks 22 
and  26.  
In the usual care, or control, arm, participants receive 12 weeks of NRT 
(nicotine replacement treatment) and one-time brief (~15 minutes) 
counseling for smoking cessation and alcohol cessation. The smoking 
cessation counseling is based on the 5 A’s model (Ask, Advise, Assess, 
Assist, Arrange) recommended by the US Public Health Service Clinical 
Practice Guidelines. Consistent with the guidelines, counselors conduct the 
following procedures: a) congratulate the participant on enrolling in the 
study, b) describe the harms related to smoking and the benefits of quitting, 
c) advise the participant to quit immediately, d) assist participants to set a 
quit date, e) encourage participants to tell friends and families about their 
quitting, and f) describe potential relapse situations and other barriers to 
quitting. The brief alcohol counseling follows Public Health Service 
guidelines and include elements such as a) presenting screening results, b) 
identifying risks, c) discussing consequences, d) soliciting commitment, e) 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 12 of 25

identifying goals, and f) giving advice and encouragement. At the end of the 
session, participants interested in additional smoking or alcohol intervention 
are referred to local and national treatment programs. 
Participants in intensive integrated smoking and alcohol counseling 
condition receive 12 weeks of NRT treatment plus weekly individual 
cessation counseling sessions. Counseling utilize CBT (cognitive behavioral 
therapy) techniques. The counselor assists participant to set and prepare for 
their quit date targeted for the day after randomization. Initial CBT sessions 
focus on identifying situations, activities, moods, and thoughts associated 
with cigarette smoking, strategies for coping with trigger events and 
smoking urges, etc.  Counseling is also be tailored to address challenges 
peculiar to homeless persons including boredom, lack of structure in daily 
life, and dealing with the stress related to meeting competing social needs 
(e.g. food, housing, safety, grooming, etc.). The remaining sessions focus on 
relapse prevention. This protocol was used in a recent study by our research 
team.  
The alcohol counseling is distinct from smoking counseling and does not 
emphasize similarities between quitting smoking and stopping alcohol and 
drug use. This is based on findings from a study that reported that 
emphasizing these similarities led to worse drinking outcomes compared to 
concurrent treatment that did not emphasize the similarities. Alcohol 
treatment is based on a CBT manual developed for Project MATCH, an 8 
year NIH multi-site alcohol treatment study and was used by our research 
team in a recent study.  About 40 minutes of each session is devoted to 
alcohol treatment to include identifying alcohol antecedents, coping with 
alcohol urges, managing thoughts about alcohol, problem solving, drink 
refusal skills, planning for emergencies, assertiveness training, and 
enhancing social support networks for alcohol abstinence. 
At weekly study sessions staff ask about any issues the participant may be 
experiencing with the products. An adverse event form is completed if 
participants report any side effects from use of the nicotine replacement 
products. Participants receive additional two-week supplies as needed. 
At each study visit, the study survey asks if the participant was hospitalized 
or visited the emergency room since their last visits. An adverse event form 
is completed if either event occurred. Study staff also assess to determine if 
the participant is currently exhibiting incoherence, disorganized speech, or 
marked loosening of associations and if so, administer the Short Blessed 
Test to assess cognitive concerns in the areas of orientation, memory, and 
concentration. Additionally, at each study visit participants are assessed for 
suicidal ideation. The Columbia Suicide Severity Rating Scale is 
administered anytime a participant answers affirmatively to the question: 
“over the last 2 weeks, how often have you been bothered by thoughts that 
you would be better off dead or of hurting yourself in some way?” If the 
result of the Columbia indicates they have intention or a plan, they are

escorted by study staff to the medical clinic at the shelter, to COPE 
(Community Outreach for Psychiatric Emergencies), or to the nearest 
hospital emergency room. 
Participants are compensated with a Visa or American Express gift card of 
varying amounts at each study visits and also receive a $5 Subway gift card 
or a non-monetary incentive such as a backpack, word finder game, pocket 
calendar, playing cards, or water bottle. During the first 12 weeks and at 
weeks 16 and 26, participants are offered a raffle draw for an additional 
incentive to increase retention at these key data collection points. 
Visa/American Express card denominations vary from $10 for most visits to 
$75 at week 26 for the final study visit and data collection survey. 
5.3 Follow-Up:

Study Population 
9.1 Inclusion Criteria:  
The study population is homeless adults who smoke cigarettes and drink 
alcohol. Homeless individuals are considered to be undervalued, often 
disenfranchised and are vulnerable due to their disadvantage in the 
distribution of social goods and services including income, housing, and 
healthcare. This study specifically targets homeless to learn how to address 
the healthcare disparities they face with lack of access to smoking cessation 
interventions and lack of research identifying successful smoking cessation 
strategies that work for homeless individuals wishing to quit smoking. 
 
Individuals must meet the following criteria to be considered for study 
inclusion: 
• Currently homeless (as defined in the Stewart B. McKinney Act passed by 
the US congress in 1987) 
• Smokes > 5 cigarettes per day in past 7 days 
• Smoked at least 100 cigarettes in lifetime 
• AUDIT score ≥5 
• Aged 18 years or older  
• Willing to attend study sessions and follow other study protocol 
9.2 Exclusion Criteria: 
Individuals will be excluded for the following reasons: 
• Use of smoking cessation medications or interventions in last 30 days 
• Unstable medical illness that requires immediate medical care 
• AUDIT score <5 or >27  
• Pregnancy or other NRT contraindications 
• Current history or in past 6 months of psychotic disorder or major 
depressive disorders that is not stable on treatment for past 3 months (as 
determined by the study psychiatrist) 
• Cognitive impairment (as measured by the Short Blessed Test) 
9.3 Screening: 
To make screening and participation convenient for participants, all study visits 
occur at local homeless shelters. Interested individuals complete an eligibility 
survey administered by study staff to determine if they are eligible to enroll. The

10-item AUDIT scale is used to screen for alcohol use disorders with scores less 
than 5 indicating abstinent or low-risk alcohol users and a score over 27 indicative 
of hazardous use or alcohol dependence. The Short Blessed Test will be 
administered to determine cognitive capacity to participate. The 7-item Psychotic 
Disorders and Mood Disorder with Psychotic Features scale of the Mini 
International Neuropsychiatric Interview (MINI) is administered to screen for 
psychotic disorders. Those who screen positive for psychotic disorders or major 
depression may be enrolled provided they have been stable in treatment for past 
three months. This determination is be made by the study Psychiatrist, Dr. Sheila 
Specker, who oversees screening and necessary referrals for these psychiatric 
disorders. To be enrolled in the study, participants must be able to meet study staff 
at designated homeless shelters. Individuals may screen for eligibility up to five 
times with a minimum one month window between screenings. This allows those 
deemed ineligible due to unstable medical conditions the ability to potentially 
enroll once their health is stable. Eligible individuals are scheduled for a follow-up 
visit to enroll and be randomized to a study condition.

10.2 Adults lacking capacity to consent and/or adults with diminished capacity to 
consent: 
Justification for inclusion of population:  
The study specifically targets homeless adult men and women some of 
whom are mentally ill, chemically dependent, members of a minority racial 
and/or ethnic group, and clearly from economically and often educationally 
disadvantaged populations. The specific aims of the study are to identify 
effective methods to assist homeless individuals interested in quitting 
smoking and drinking alcohol with the understanding that methods that are 
effective in the general public may not be effective with individuals facing 
the challenges of homelessness as well the life challenges contributing to 
their homelessness - mental illness, substance abuse, structural racism, and 
lack of economic resources and education. 
The study has numerous validated assessments that are administered as part 
of the eligibility screening process and the weekly data collection survey 
process that assess for ability and competency to enroll in the study and to 
maintain participation once enrolled. Assessments include assessing for 
cognitive ability (Short Blessed Test), alcohol withdrawal (Clinical Institute 
Withdrawal Assessment of Alcohol Use, Revised), physical health 
(documentation of hospital and emergency room visits), mental health 
(PHQ-9, MINI Anxiety, MINI Psychotic Symptoms), suicidal ideation 
(Columbia Suicide Severity Rating Scale), current alcohol use and 
breathalyzer testing to ensure potential and current participants are capable 
and able to enroll and participate in the study tasks. 
We minimize the risks by administering numerous assessments at eligibility 
screening and at each study session to ensure that at each study visit the 
participant is coherent, medically and psychologically stable, and not 
impaired by alcohol or alcohol withdrawal.   
 
10.3 Additional Safeguards: 
The study does not enroll pregnant women, does not involve neonates, 
prisoners or individuals under the age of 18. 
11.0 Local Number of Participants 
11.1 Local Number of Participants to be Consented:  
We plan to enroll a minimum of 428 to allow data analysis with a maximum 
enrollment of 645 participants. 
 
12.0 Local Recruitment Methods 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 17 of 25 
Revised: April 19, 2017 
12.1 Recruitment Process: 
Study participants are recruited from homeless shelters and facilities in the 
Minneapolis/St Paul area that serve homeless adults. Homeless shelters 
include Dorothy Day Center, Salvation Army Harbor Light, United Gospel 
Mission, Naomi Family Center, Emma Norton Center, Our Savior’s Shelter, 
St. Stephen’s Shelter, and Simpson House. Organizations serving homeless 
adults include the Catholic Charities Opportunity Centers, Listening House, 
the Veteran’s Service Center, Hennepin and Ramsey County detoxification 
centers, Sharing and Caring Hands, Higher Ground and the Hennepin 
County Healthcare for the Homeless programs. Recruiting from multiple 
homeless shelters and service providers make the study more accessible for 
participants and ensures a more representative sample.  
Study staff post recruitment flyers with tear-off tabs that contain the study 
phone number and email and hand out half-page flyers to individuals who 
express interest in the study the above-listed sites. 
12.2 Source of Participants: 
Participants are recruited from homeless shelters and organizations 
providing services to homeless adults through face-to-face contact and from 
recruitment flyers with the study phone number and email address to contact 
the study. 
12.3 Identification of Potential Participants: 
Potential participants self-identify in response to posters and to the study 
staff during outreach at selected sites. Interested individuals complete an 
eligibility survey that is administered by study staff to determine if they 
meet the inclusion requirements of the study. 
12.4 Recruitment Materials:  
The study uses two types of print materials to recruit. One is a full page (8 
½” x 11”) poster with tear-off tabs at the bottom. These are posted on the 
walls of various homeless shelters and service organizations that serve 
homeless adults. The other is a half-sheet (8 ½” x 5 ½”) flyer that is handed 
to individuals expressing an interest in the study at the various homeless 
shelters and service organizations that serve homeless adults (as listed in 
12.1 above). 
12.5 Payment:  
Participants are compensated at each study visit they attend. Compensation 
varies depending on the time the visit is expected to take and the data that is 
collected at that visit. Compensation includes gift cards (Visa and/or 
American Express) and small incentives. Incentives include bus tokens, 
backpacks, pocket calendars, water bottles, note pads, word find book 
games, Subway gift cards ($5), and playing cards. Participants are also 
offered a raffle draw during the first 12 weeks of the study when the study 
treatment (nicotine replacement treatment) is administered and at weeks 16 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 18 of 25 
Revised: April 19, 2017 
and 26 when alcohol use is assessed. Raffle prizes include bus tokens (50 
chances), $5 Subway gift cards (40 chances) and $10 gift cards (10 
chances). Compensation is given at the end of each study visit the 
participant attends. Over the course of the study participants can earn up to 
$285 in Visa or American Express gift cards and incentives valued at up to 
$145 for a total of $430 in total compensation in addition to small raffle 
winnings. Payments are given only to the study participant, and there are no 
research experience points awarded. 
13.0 Withdrawal of Participants 
13.1 Withdrawal Circumstances: 
Participants may be withdrawn from the research without their consent if 
they harass or otherwise intimidate staff with threats of physical or sexual 
violence. 
13.2 Withdrawal Procedures: 
Participants may voluntarily withdraw from the study if they find they are 
no longer interested in participating or if they will otherwise be unable to 
continue participation. Those who voluntarily withdraw can return and 
continue their participation at any point in the future during the 26 week 
study period. For example, a participant may leave the area for a job, family, 
or other reason but return and continue participation. When returning, they 
will re-enter the study at the week they would be at if they had participated 
continuously. Each study visit has a window of time before and after the 
ideal date of their visit. Study visits can only be completed during the visit 
window.   
13.3 Termination Procedures: 
There is not a procedure for voluntary withdrawals. Those terminated 
involuntarily are notified in writing at a scheduled meeting to provide the 
written termination letter and any compensation that may be due to them. 
14.0 Risks to Participants 
For each risk or set of risks below, include the procedures to be performed to 
lessen the probability, magnitude, duration, or reversibility of those risks. 
14.1 Foreseeable Risks:  
There are some risks related to quitting smoking that a participant may 
experience while in the study. These may include headaches, being 
uncomfortable, changes in mood, weight gain, and the possibility of going 
back to smoking. Possible side effects of the nicotine patch may include 
skin irritation or rash and problems with sleeping. These are generally mild 
and stop after a few days of using the patch.  
 
Participants are asked by staff at every individual session about side effects 
from the patch or quitting and any health problem that may interfere with 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 19 of 25 
Revised: April 19, 2017 
their ability to use the patch. Participants are given a specific phone number, 
(612) 625-1850, to report serious side effects and be advised on what to do 
if the patch or anything related to the study makes then uncomfortable.  
 
Use of the nicotine patch will be under supervision of Dr. Okuyemi. 
Participants will be prompted to discuss any side effects during follow-up 
visits and will be given the study office phone number (24-hour coverage) to 
contact study staff and/or the investigators to report adverse events. We 
follow the NIH guidelines for reporting adverse events to the IRB. Any 
problems needing medical attention will be referred to Dr. Okuyemi and the 
Health Care for the homeless clinics in Minneapolis and St. Paul which are 
federally qualified community health centers that provide medical care and 
social services for homeless persons. The patch is discontinued in patients 
who become pregnant or develop a contraindication. Patients are instructed 
not to smoke cigarettes during nicotine treatment therapy. Due to the high 
prevalence of psychiatric and substance abuse co-morbidities in homeless 
populations, in the proposed study we expect to encounter participates who 
have one or more of these co-morbidities. It is also possible after enrolling 
in the study for some participants to develop these co-morbid disorders. 
Counselors are trained to identify such participants and the study 
psychiatrist directly oversees the protocol’s implementation. For each case 
the psychiatrist also makes a determination as to whether the participant is 
mentally stable enough to continue participation in the study. 
 
There are also some risks from stopping alcohol use, however, the study 
screens out heavy alcohol users to avoid enrolling those at risk for 
experiencing alcohol withdrawal. Additionally at every study session 
alcohol use is measured with an alcohol breathalyzer test and the 
administration of the CIWA, an alcohol withdrawal assessment screen to 
ensure a participant is not intoxicated or in alcohol withdrawal. If the CIWA 
indicates an individual is experiencing alcohol withdrawal, study staff walk 
the person to the on-site medical clinic for further evaluation. 
 
14.2 Reproduction Risks: 
Women who are pregnant or breastfeeding are not allowed to enroll in the 
study because of possible harms the nicotine patch could cause to the fetus. 
Women of childbearing age must take a urine pregnancy test to ensure they 
are not pregnant, and if not pregnant must agree to use an effective method 
of preventing pregnancy while using nicotine patch. Women are instructed 
to report to staff should they become pregnant while using the nicotine patch 
and to immediately stop using the patch. 
14.3 Risks to Others: 
N/A 
15.0 Potential Benefits to Participants 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 20 of 25 
Revised: April 19, 2017 
15.1 Potential Benefits: 
Anticipated benefits of alcohol and tobacco cessation outweigh the minimal risks 
associated with the nicotine replacement therapy and counseling. Given their 
already compromised health status, homeless smokers who abuse alcohol 
are at an extremely high risk of synergistic health effects of tobacco and 
alcohol. Despite this high disease risk, limited empirical data is available 
about how to extend effective smoking cessation and alcohol treatment to 
homeless populations. The current application therefore breaks new ground 
by assessing methods to extend evidence-based treatments to a vulnerable 
population. The prevalence of cigarette smoking among alcohol dependent 
persons is up to 70%, more than three times the rate in general population. 
In addition to high prevalence of tobacco use in homeless populations, the 
rates of alcohol and drug abuse are also high in this population. Cigarette 
smokers drink alcohol more often and more heavily than nonsmokers. 
Studies have shown that the health consequences of chronic alcohol and 
tobacco use are synergistic. In one study of 4,928 alcoholics, the high cancer 
mortality was attributed solely to smoking. Another study by Hurt et al. 
found a 48% cumulative mortality at 20 years after inpatient alcohol 
treatment attributable more to tobacco-related diseases than to alcohol.  
16.0 Data Management 
16.1 Data Analysis Plan: 
The primary analysis will be based on an intention to treat (ITT) analysis, 
i.e., participants will be analyzed in the treatment to which they were 
randomized. The intervention effects for the primary outcomes of week 26 
biochemically verified 7-day abstinence from cigarette smoking (Hyp 1) and 
week 26 90-day abstinence from alcohol consumption (Hyp 2) will be tested 
using Chi-square tests. Any participants lost to follow-up will be classified 
as treatment failures (i.e. smoker or drinker). Bonferroni procedures will be 
used to control for experimentwise Type I error rate. Abstinence rates and 
corresponding 95% confidence intervals will be estimated and summarized 
using appropriate tabular and graphical methods. Supportive analyses will 
examine baseline variables including demographic (age, sex, income, 
education), nicotine dependence, withdrawal symptoms, motivation and 
confidence, self-efficacy, social support, perceived stress, and depressive 
symptoms in terms of their relationship to study outcomes. Analyses 
accounting for these measures will be conducted using multiple logistic 
regression including intervention groups as controlled factors. Thus we can 
assess whether the main conclusions from the primary analysis are robust 
for the inclusion of these baseline variables. For hypothesis 3, Fisher exact 
test will be used to compare the biochemically verified 7-day smoking 
abstinence rates at week 26 follow-up between the participants who receive 
the Intensive Smoking intervention (IS) and participants who receive Usual 
Care (UC). Supportive analysis will be conducted using multiple logistic 
regression including the intervention group as predictor adjusting baseline 
covariates to assess whether the result from secondary analysis is robust for 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 21 of 25 
Revised: April 19, 2017 
the inclusion of baseline covariates. Analyses for exploratory aims: To 
examine how smoking cessation, alcohol abstinence, smoking reduction, 
and alcohol reduction at weeks 12, 26, and 52 follow-up relate to the 
psychosocial factors, such as level of depression, hopelessness, and 
perceived stress, other substance abuse, opportunities for employment and 
housing and overall health, separate repeated measures logistic regressions 
with generalized estimating equations (GEE) or linear mixed models that 
accounts for the repeated measures structure of the data will be used to 
examine the associations between each individual psychosocial predictors 
and smoking or alcohol outcomes at weeks 12, 26, and 52 follow-ups. 
Interactions terms between these factors and intervention indicators will be 
further tested in the above models. Model validation will use analytic and 
graphical techniques to check assumptions of linearity, homoscedasticity, 
multivariate normality, and independence of residuals. Descriptive statistics 
will be used to summarize and ANOVA or Chi-square tests will be used to 
examine participants’ perceptions of acceptability and usefulness of 
components of the various interventions.

16.3 Data Integrity: 
Participant enrollment, study participation, and retention are tracked on an 
Excel spreadsheet as well as in REDCap, the study database. All eligibility 
screening forms are completed on paper and then entered into the REDCap 
database. Participant data is entered into a REDCap database from both 
paper forms completed at the beginning of the study and from direct data 
entry in the field during study visits. The spreadsheet and REDCap are 
regularly reconciled for quality control.

17.0 Confidentiality 
17.1 Data Security: 
Data will be stored in REDCap databases.  Data for this study will be 
entered into interactive, relational REDCap databases, which use a MySQL 
database via a secure web interface with data checks used during data entry 
to ensure data quality. REDCap includes a complete suite of features to 
support HIPAA compliance, including a full audit trail, user-based 
privileges, and integration with the institutional LDAP server. The MySQL 
database and the web server will both be housed on secure servers operated 
by the University of Minnesota Academic Health Center’s Information 
Systems group (AHC-IS). The servers are in a physically secure location on 
campus and are backed up nightly, with the backups stored in accordance 
with the AHC-IS retention schedule of daily, weekly, and monthly tapes 
retained for 1 month, 3 months, and 6 months, respectively. Weekly backup 
tapes are stored offsite. The AHC-IS servers provide a stable, secure, well-
maintained, and high-capacity data storage environment, and both REDCap 
and MySQL are widely-used, powerful, reliable, well-supported systems. 
Access to the study's data in REDCap will be restricted to the members of 
the study team by username and password. 
Consent forms or other study information will not be placed in any 
participant medical, employment or education records.. 
18.0 Provisions to Monitor the Data to Ensure the Safety of 
Participants 
18.1 Data Integrity Monitoring.  
A Data Safely Monitoring Board (DSMB) was established in 
January 2016. The first meeting was held in April 2106. The 
qualification for members includes research knowledge and 
experience with tobacco cessation, homeless adults, health 
disparities with vulnerable and underserved populations and 
statistical methodologies. Members were selected based on these 
qualifications, their interest, and their availability to attend meetings 
and review data. 
DSMB members determine the frequency of meetings based on the 
reports provided them. Each report contains a detailed recruitment 
update that includes current enrollment and recruitment, consort 
diagram, and a target vs. actual recruitment chart; a description of 
the study sample by treatment group; a safety assessment including 
adverse events and serious adverse events by treatment group; a data 
collection update including counseling treatment visits and weekly 
visits by treatment group; and a list of protocol violations. 
DSMB members monitor enrollment numbers and review blinded treatment 
data to ensure significant sample size and when necessary, to propose design 

PROTOCOL TITLE: Enhancing Smoking Cessation in the Homeless Population 
VERSION DATE: 11/15/2017 
 
Page 23 of 25 
Revised: April 19, 2017 
changes to ensure significant outcomes. Monitoring is accomplished through 
regular meetings to share data to understand any enrollment, participant 
safety, or unforeseen issues affecting study outcomes and deadlines that may 
require design, endpoints or outcomes. The monitors are responsible to 
review the data and propose sustainable solutions to maintain the research 
goals and outcomes. The reports compiled for DSMB members are shared 
with co-investigators with treatment group data blinded. 
Data Safety Monitoring.  
Study participants are asked to report any adverse events they have 
experienced during their study participation at each study visit. Participants 
are asked if they were hospitalized or sought emergency medical care since 
their last visit. All hospitalizations and emergency room visits and the 
reason are recorded and paper by the study team and entered into REDCap, 
the study database. The study PI, a medical doctor with extensive tobacco 
cessation research experience, reviews all adverse events. All adverse events 
and serious adverse events are regularly report to the DSMB as noted above 
after a review by the study statistician to ensure if any harms are occurring. 
Currently there are no identified conditions that could trigger an immediate 
suspension of work. Nicotine replacement products have been on the market 
and proven to be safe for a number of years. This is the second phase of a 
study in the same population where no serious safety issues have occurred. 
19.0 Provisions to Protect the Privacy Interests of Participants 
19.1 Protecting Privacy: 
All participant contact is conducted by trained research staff and occurs in a 
private office or a dedicated space that affords participant privacy. 
19.2 Access to Participants: 
The research does not involve collecting data from any kind of participant 
record.

ability to participate. All participants take an alcohol breathalyzer test at 
every study visit and must test below .08 in order to complete the study 
visit. Participants are also assessed at every study visit for cognition and for 
suicidal ideation. Staff assess for incoherence, disorganized speech, or 
marked loosening of associations and administer the Short Blessed Test if 
concerned. If the participant does not pass the Short Blessed Test, they are 
rescheduled. Consent is obtained in writing.  
21.2 Waiver or Alteration of Consent Process (when consent will not be 
obtained):  
N/A 
21.3 Non-English Speaking Participants: 
Non-English speakers are not enrolled in the study. 
21.4  Participants Who Are Not Yet Adults (infants, children, teenagers under 18 
years of age): 
Individuals must be at least 18 years old to enroll. 
21.5 Cognitively Impaired Adults, or adults with fluctuating or diminished 
capacity to consent: 
All participants take an alcohol breathalyzer test at every study visit and 
must test below .08 in order to complete the study visit. Participants are also 
assessed at every study visit for cognition and for suicidal ideation. Staff 
assess for incoherence, disorganized speech, or marked loosening of 
associations and administer the Short Blessed Test if concerned. If the 
participant does not pass the Short Blessed Test, they are rescheduled.

22.0 Setting 
22.1 Research Sites: 
As noted in other sections above, study participants are recruited from 
homeless shelters and facilities in the Minneapolis/St Paul area that serve 
homeless adults. Homeless shelters include Dorothy Day Center, Salvation 
Army Harbor Light, United Gospel Mission, Naomi Family Center, Emma 
Norton Center, Our Savior’s Shelter, St. Stephen’s Shelter, and Simpson 
House. Organizations serving homeless adults include the Catholic Charities 
Opportunity Centers, Listening House, the Veteran’s Service Center, 
Hennepin and Ramsey County detoxification centers, Sharing and Caring 
Hands, Higher Ground and the Hennepin County Healthcare for the 
Homeless program. All research procedures are performed at the sites.

24.0 Resources Available 
24.1 Resources Available: 
The study does not have a student investigator. The feasibility of the 
recruiting numbers was determined by the results of the PTQ I study. 
However, we have found it necessary to adjust the original proposed 
numbers due to a large number of individuals unable to meet the criteria for 
alcohol use. The new numbers were calculated by the study statistician, the 
NIH project officer and the DSMB. The study began enrolling participants 
in January 2015 and expect to complete enrollment at the end of March 
2018 which leaves and additional year for follow-up, data cleaning and 
analysis and development of manuscripts. 
The study staff conduct the research in homeless shelters and service 
organizations in Minneapolis and St Paul. When not working in the shelters, 
they work from study offices at UROC in Minneapolis and a commercial 
site in downtown St Paul, both of which are close to the two primary 
homeless shelters serving large number of homeless adults. All study sites 
have medical and psychological services available onsite through Healthcare 
for the Homeless. Staff also carry referral information for Hennepin and 
Ramsey county crisis hotlines and the national suicide hotline for 
participants who screen for suicidal ideation. The study psychiatrist is on-
call for telephone consultations and the study has written procedures for 
calling emergency services if the on-site healthcare clinic is unable or 
unavailable to assist. 
 
New staff complete all required trainings before working on the study and 
read the study procedures and become familiar with the study data 
collection forms and tools. Once in the field with the study team, they 
observe how the study is conducted first and then are trained to administer 
the study surveys. The study team observes new staff in administering 
surveys until they are determined to be proficient and able to conduct the 
field work without supervision. The study team meets weekly to discuss 
study issues and to review protocols and procedures to ensure fidelity to the 
protocol.
