What this Trial Is About
Researchers are evaluating the Smokefree Family Living (SFL) intervention to see if it helps Chinese American smokers quit smoking and reduces exposure to third-hand smoke (THS) among smokers and their non-smoking household members. THS refers to tobacco contamination that remains on surfaces like carpets, walls, and furniture even after smoke clears. The study focuses on Chinese American males, particularly those with limited English skills, who have high smoking rates. The SFL program combines smoking cessation education with THS awareness and cleaning strategies. The study includes a family-based intervention development phase followed by a randomized clinical trial with 320 smoker-household member pairs from Chinese American communities. Participants are assigned to one of two groups: one group receives two educational sessions focused on quitting smoking plus THS education and cleaning strategies after six months; the other group receives the same educational sessions but with THS education and cleaning strategies included during the second session. Both groups receive follow-up phone calls, a Healthy Family Action Plan, smoking cessation resources, and urine sample collections. Non-smoking household members wear silicone wristbands for two days at each assessment to measure THS exposure. Participants attend educational sessions and follow-up calls, provide urine samples throughout the study, and non-smoking members wear wristbands to track exposure. Researchers measure smoking quit rates at six months as the primary outcome and assess tobacco smoke biomarker changes and quit rates at twelve months. The study also explores individual and social factors influencing cessation, the timing and long-term effects of the THS intervention, and the feasibility of wristbands for exposure measurement. Participants are followed for up to 12 months with assessments at six and twelve months after intervention completion.

Participants also receive a Healthy Family Action Plan, a smoking cessation resource guide, and set goals on study.
2 educational sessions (in-person or video conferencing) and 2 follow-up phone calls
Duration - Up to 6 months
Participants receive third-hand smoke education and cleaning strategies either during the second educational session or at 6 months after the initial sessions depending on study arm.
1 visit for third-hand smoke education and cleaning strategies
Duration - Up to 12 months
Participants undergo urine sample collection at baseline and throughout the study. Non-smoking household members wear a silicone wristband for 2 days at each assessment to measure third-hand smoke exposure.
Urine samples collected at multiple assessments; silicone wristband worn for 2 days at each assessment by non-smokers
Duration - 6 to 12 months post-intervention
Participants are followed up at 6 and 12 months after completion of the intervention to assess smoking cessation and exposure to tobacco smoke.
