A Smoke-Free Home Intervention in Tribal Communities
A study testing Best Practice, Smoking Cessation Intervention and Survey Administration in people with Tobacco-Related Carcinoma, run by Emory University at 1 site in United States.
Trial summary
This clinical trial evaluates a smoke-free home intervention for reducing exposure to secondhand smoke from commercial tobacco in homes of participants who live in rural tribal communities.

About this study
Official title: Assessing the Effectiveness of a Smoke-Free Home Program in Tribal Communities
This clinical trial evaluates a smoke-free home intervention for reducing exposure to secondhand smoke from commercial tobacco in homes of participants who live in rural tribal communities. Smoke-free homes are an innovative and relatively untapped strategy for cancer prevention in rural tribal communities. Smoke-free policies, including those that target homes, can reduce exposure to secondhand smoke and support smoking cessation. Rural and racial/ethnic inequities intersect to increase tobacco-related harms among Indigenous populations. A smoke-free home program may improve the health of the household as well as impact smoking behavior among the family unit by reducing secondhand smoke exposure.
Read the detailed description
PRIMARY OBJECTIVE:
- To assess the effectiveness of a smoke-free homes intervention for tribal communities.
OUTLINE: Participants are randomized to 1 of 2 groups.
GROUP I: Participants receive the smoke-free home program, consisting of mailed educational information about smoke-free homes at enrollment and in weeks 4 and 6, and attend one coaching call in week 2.
GROUP II: Participants receive usual care on study. Participants may optionally receive the smoke-free home program following the 6 months follow-up.
After completion of study intervention, participants are followed up at 3 and 6 months.
- Conditions
- Tobacco-Related Carcinoma
- Being tested
- Best Practice, Smoking Cessation Intervention, Survey Administration

What is being measured
The primary outcome is the main question the study is designed to answer.
Self-Reported Smoke-Free Home
Which statement best describes rules about smoking inside your home? There are no rules about smoking inside your home? Smoking is not allowed anywhere inside your home? Smoking is allowed in some places or at some times in your home? Smoking is allowed anywhere inside your home? Those answering that smoking is not allowed anywhere inside their home are classified as having a smoke-free home. It will be self-reported \& measured using air nicotine monitor from a subset of 20% participants to assess validity of the self-report, adjusting for possible traditional uses of tobacco and use of electronic cigarettes. Receiver-operator curve analysis to determine the optimal thresholds for a smoke-free home \& complete case data, two-level logistic multilevel models accounting for nesting of participants in tribal communities with group assignment predicting a binary smoke-free home status (full ban/no full ban).
Measured: At 3 and 6 months
Secondary outcomes (4)
Smoke-Free Vehicles Assessed Via Telephone Interview
Smoke-Free Vehicles will be assessed via telephone interview using a measure adapted from the Centers for Disease Control and Prevention (CDC)'s National Adult Tobacco Survey, 2009-2010. What about smoking cigarettes in your vehicle(s) (including cars, SUVs, and trucks) - would you say: There are no rules about smoking in the vehicle(s), smoking is sometimes allowed in the/some vehicle(s), smoking is never allowed in the/any vehicle, no car, don't know. Those answering smoking is never allowed in the/any vehicle are classified as having a smoke-free vehicle rule. We will use 3-level logistic growth curve models using Statistical Analysis System (SAS) procedure (PROC) Bayesian Generalized Linear Mixed Modeling (BGLIMM) to model all of the collected data. Data cleaning, descriptive analyses, as well as bivariate and multilevel modeling, will be conducted using Statistical Analysis System (SAS) version 9.4. Mediation analyses will be conducted in Mplus statistical software version 8.5.
Measured: At 3 and 6 months
Secondhand Smoke (SHS) Exposure In The Home Assessed via Telephone Interview
SHS exposure in the home will be assessed via telephone interview using a measure adapted from the Centers for Disease Control and Prevention (CDC)'s National Youth Tobacco Survey, 2023. During the past 7 days, how many days have people smoked in your home in your presence? Response options 0 to 7. We will use 3-level logistic growth curve models using Statistical Analysis System (SAS) procedure (PROC) Bayesian Generalized Linear Mixed Modeling (BGLIMM) to model all of the collected data. Data cleaning, descriptive analyses, as well as bivariate and multilevel modeling will be conducted using Statistical Analysis System (SAS) 9.4. Mediation analyses will be conducted in Mplus statistical software version 8.5.
Measured: At 3 and 6 months
Number of Cigarettes Smoked In the Home
Will use 3-level logistic growth curve models using Statistical Analysis System (SAS) procedure (PROC) Bayesian Generalized Linear Mixed Modeling (BGLIMM) to model all of the collected data. Data cleaning, descriptive analyses, as well as bivariate and multilevel modeling will be conducted using Statistical Analysis System (SAS) version 9.4. Mediation analyses will be conducted in Mplus statistical software version 8.5.
Measured: At 3 and 6 months
Public Support for Smoke-Free Tribal Housing Assessed Via Telephone Interview
To what extent do you support or oppose a complete cigarette smoking ban in the following settings: tribally owned multi-unit housing. Response options include a range from 1 (strongly oppose) to 4 (strongly support).
Measured: At 3 and 6 months
