Project Title

Smoke-Free Homes (Brief Interventions to Create Smoke-Free Home Policies in Low-Income Households)

Funding Dates



The purpose of the research was to develop, evaluate, and disseminate a brief smoke-free homes intervention through the existing national infrastructure of 2-1-1. 2-1-1 is a nationally designated 3-digit telephone exchange, similar to 9-1-1 for emergencies or 4-1-1 for directory assistance, that links callers to community-based health and social services. The proposed research had four specific aims: (1) conduct formative research on intervention messages and materials for promoting smoke-free homes in low-income populations, applicable to both smokers and nonsmokers as household change agents; (2) conduct a randomized controlled trial in the Atlanta 2-1-1 service area to evaluate the effectiveness of a brief intervention to create smoke-free homes among 2-1-1 callers; (3) conduct replication studies in Houston and North Carolina 2-1-1 systems to systematically test the intervention in varied populations and tobacco control climates; and (4) disseminate the research-tested smoke-free homes intervention through a variety of mechanisms.
