Summary

This project seeks to determine the effectiveness of two types of interventions to reduce exposure to secondhand smoke in residential buildings. One intervention is geared toward all building residents (resident endorsement) and the other targets smokers (smoking reduction via relocation and reduction in personal smoking/cessation) with the goal of reducing personal smoking and secondhand smoke exposure.

Detailed description

Smoke-free housing policies in multi-unit housing are promising and increasingly widespread interventions to reduce smoking and secondhand smoke exposure. Little research has identified factors that improve compliance with smoke-free housing policies in low-income multi-unit housing and test corresponding solutions. The proposed randomized controlled trial (RCT) addresses key gaps in knowledge and capitalizes on key scientific opportunities by: 1) leveraging the federal mandate to ban smoking in a public housing system of more than sufficient size to conduct an adequately powered RCT; 2) expanding our understanding of smoke-free policy compliance beyond policy implementation by testing two novel treatments: a) in-residence smoking cessation and b) resident endorsement, while 3) addressing population and location-specific tobacco-related disparities. The investigators hypothesize that the relocation/cessation plus resident endorsement intervention will yield significantly larger reductions in personal smoking and secondhand smoke exposure, compared to standalone interventions and the standard approach.
