What is the purpose of this trial?

This trial aims to help Chinese American smokers quit smoking and reduce exposure to third-hand smoke (THS), which adheres to surfaces like carpets and walls. The study tests an intervention called Smokefree Family Living (SFL), combining smoking cessation education with strategies to clean THS. Participants include current smokers and their non-smoking household members. Smokers who have smoked in the last 30 days and have a non-smoking household member are well-suited for this trial. As an unphased trial, this study offers participants a unique opportunity to contribute to research that could enhance health outcomes for their community.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It focuses on smoking cessation and third-hand smoke education.

What prior data suggests that the Smokefree Family Living intervention is safe?

Research has shown that family-based programs to help people stop smoking, such as Smokefree Family Living (SFL), are generally easy for participants to manage. Studies have found that these programs can reduce smoking and increase quit attempts. Participants often notice improved air quality in their homes, leading to reduced exposure to harmful substances. Reports of negative effects from these educational and behavioral programs are rare, suggesting they are safe for everyone involved, including non-smokers living with smokers. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Smokefree Family Living (SFL) approach because it doesn’t just focus on the smoker but involves the entire family in the quitting process. This strategy includes educational sessions and personalized action plans that empower families to create a healthier home environment. By engaging family members and integrating education on thirdhand smoke (THS) and cleaning strategies, SFL offers a comprehensive approach that could lead to more sustainable quitting outcomes compared to traditional smoking cessation methods that primarily target individual smokers.

What evidence suggests that this trial's treatments could be effective for smoking cessation and reducing third-hand smoke exposure?

Research has shown that programs involving families can help people smoke less and attempt to quit more often. In this trial, the Smokefree Family Living (SFL) program is one of the approaches tested. It teaches people how to stop smoking and reduce exposure to smoke residue in their homes. This method has shown promise in helping people quit smoking and reducing harmful tobacco residues in living areas. Early results suggest that involving family members can boost motivation and support for quitting. Overall, programs like SFL have helped participants smoke less and consider quitting more seriously. ^{6 7 8 9 10}

What Are the Treatments Tested in This Trial?

Interventions

• Smokefree Family Living (SFL)

Trial Overview The study tests the Smokefree Family Living (SFL) intervention, combining Quit Smoking education with strategies on avoiding third-hand smoke through cleaning. Participants will also provide urine samples, wear silicone wristbands for monitoring, and partake in interviews and focus groups.

How Is the Trial Designed?

Group I: Intervention Development (Focus group + Interview) Experimental Treatment 1 Intervention

To achieve information gathering and preliminary adaptation design to prepare for the randomized clinical trial, focus groups and individual interviews with 24 participants (6 Chinese current smokers; 6 former smokers who have stopped smoking within the past 2 years; and 12 family/household members living with a current/former smoker) to review the newly developed or updated intervention materials. The Community Advisory Board (CAB) will also be involved in providing input.

Group II: Arm II: Smokefree Family Living Group (SFL) Experimental Treatment 6 Interventions

Participants attend two QS educational sessions over 45-60 minutes one month apart and receive two follow-up phone calls over 15-30 minutes 1-2 weeks after each session over 6 weeks. During the second QS educational session, participants receive THS education and cleaning strategies. Participants also receive a Healthy Family Action Plan as well as a smoking cessation resource guide and set goals on study. Additionally, participants undergo urine sample collection throughout the study and non-smoking family/household members will wear a silicone wristband for 2 days at each assessment.

Group III: Arm I: Quit Smoking for a Healthy Family Group (QS) Active Control 6 Interventions

Participants attend two QS educational sessions over 45-60 minutes one month apart and receive two follow-up phone calls over 15-30 minutes 1-2 weeks after each session over 6 weeks. Participants also receive a Healthy Family Action Plan as well as a smoking cessation resource guide and set goals on study. Participants then receive THS education and cleaning strategies at 6 months after the initial QS curriculum. Additionally, participants undergo urine sample collection throughout the study and non-smoking family/household members will wear a silicone wristband for 2 days at each assessment.
