Brief Summary

The focus of this study is on expanding access to voluntary smoke-free homes to formerly homeless residents residing in permanent supportive housing and examining the impact of this intervention on reducing tobacco-caused disparities. In this study, the principal investigator will conduct a multi-site, community-based cluster-randomized wait-list controlled trial of the multi-faceted smoke-free home intervention among 400 permanent supportive housing residents residing in 20 permanent supportive housing sites across the San Francisco Bay Area with the goal of increasing voluntary adoption of smoke-free homes.

Conditions

Second Hand Tobacco Smoke; Smoking Cessation

Keywords

Smoke-free home; Smoking cessation; Permanent supportive housing

Outcome Measures

Primary Outcomes (1)

• Proportion of Resident-participants Who Adopt a Smoke-free Home Voluntarily

  The proportion of resident-participants who self-reported a voluntary adoption of smoke-free homes for \>=90 days at 6 months follow-up will be reported.

  6 months

Secondary Outcomes (1)

• Proportion of Resident-participants Who Achieve Abstinence

  6 months

Study Arms (2)

Smoke-free home permanent supportive housing (PSH) resident intervention + Staff Intervention

EXPERIMENTAL

Study staff will deliver a one hour, one-on-one counseling to PSH resident-participants that includes: (1) a step-by-step guide on how to voluntarily adopt a smoke-free home, (2) information on second hand smoke (SHS) and third-hand smoke, alternative combustible tobacco and nicotine product use, cannabis-tobacco co-use, effects of SHS on kids and pets,(3) a worksheet on calculating personal costs related to tobacco use, and (4) pledges to designate one's home smoke-free. Staff at various sites will be trained by the study team (staff-participants) to provide support to the resident-participants in tobacco cessation. At follow-up assessments, the study team will ask resident-participants whether they had a chance to view the intervention materials in between visits and will offer an opportunity for resident-participants to discuss conflicts that they had experienced around smoke-free home adoption and will provide strategies to address these roadblocks.

Behavioral: Resident counselling; Behavioral: Staff Training

Wait-List Control (Usual Care)

OTHER

The current standard of care includes no interventions for smoke-free home adoption or referrals to smoking cessation resources. Wait-list group will be given the option to receive Smoke-Free Home (SFH) intervention after intervention group completes the 6-month follow-up. Staff at various sites will be trained by the study team (staff-participants) to provide support to the resident-participants in tobacco cessation.

Behavioral: Staff Training

Smoke-free home permanent supportive housing (PSH) resident intervention + Staff Intervention

Staff Training BEHAVIORAL

A two-hour training for PSH staff-participants on how to provide referrals to smoking cessation programs using materials previously developed from UCSF's 'Rx for change' curriculum for service providers, directed toward empowering PSH staff-participants to provide referrals to local cessation services using the ask, advise, and refer approach. The training will address nicotine addiction, tobacco use among PSH resident-participants, pilot data, brief cessation counseling (ask, advise, and refer), and local resources for cessation. Because PSH resident-PSH staff encounters will take place as part of routine care, the study team will request permission from a random sample of staff-participants and resident dyads (n=40) to record these interactions to assess fidelity.
