Study Overview
Brief Summary
Comprehensive smoke-free policies have the potential to substantially reduce tobacco-related disparities among populations in subsidized housing. This study fills this gap by identifying approaches to increase the implementation of smoke-free policies in all types of subsidized housing by increasing the voluntary adoption of smoke-free homes and promoting access to smoking cessation services.
Detailed Description
OBJECTIVES:
The investigators will build on previous studies, where a smoke-free home intervention to increase voluntary adoption of smoke-free homes in permanent supportive housing for formerly homeless adults was developed and evaluated.
Aim 1: To estimate the effect of our adapted smoke-free home intervention on the primary outcome of residents' voluntary adoption of smoke-free homes and the secondary outcome of biochemically-verified tobacco abstinence at 6-months follow-up.
Aim 2: To determine the cost of our adapted smoke-free home intervention and determine whether it is a cost-effective use of health care resources.
Aim 3: To evaluate variation in stakeholders' perspectives on the adapted smoke-free home intervention's adaptability, scalability and sustainability.The proposed intervention can expand access to smoke-free policies and smoking cessation services in subsidized housing, thereby reducing racial/ethnic disparities in tobacco use, tobacco exposure and chronic disease in these populations.

Arms & Interventions
Waitlist Control Group
The current standard of care does not include any interventions for smoke-free home adoption or referrals to tobacco treatment resources. At the end of the primary endpoint (6 months), control participants will be offered the intervention.
Intervention
The study's investigators will train bilingual study staff to deliver the intervention to residents using a script that matches the content in the smoke-free home intervention pamphlet. The in-person delivery of the intervention and pamphlet will be the primary modes of intervention delivery to residents. The pamphlet will include: (1) the harms of tobacco, e-cigarette use, cannabis use and exposure (secondhand and thirdhand), (2) an exercise to calculate personal cost of tobacco use, (3) benefits of a smoke-free home, (4) skill-building on how to adopt a smoke-free home, and (5) motivational language on smoke-free home adoption. The study staff will qualitatively assess participants' knowledge by prompting questions on the topics covered and will refer participants to lay-health workers (LHWs) for one-on-one coaching. Participants will receive a pledge to designate their homes smoke-free.
Intervention: Smoke-free home resident intervention (Behavioral)
