Study Details

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.

Arms

  • Experimental: 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.
  • No Intervention: 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.

Primary Outcome Measure

Percentage of participants adopting a smoke-free home for ≥90 days [ Time Frame: 6 months ]
