NCT02307734

Brief Summary

This project proposes two aims. The first aim is to evaluate the efficacy of a family-focused intervention in promoting smoking cessation in Chinese and Vietnamese male smokers using a 2-arm cluster randomized controlled trial with assessments at baseline, 6, and 12 months targeting 360 smoker-family dyads. Half of the participants will be assigned to the proposed intervention, and the remaining half will be assigned to an attention-control condition where they will receive education on healthy eating and physical activity. The second aim is to explore mediators to identify key psychosocial and behavioral processes that underlie how the intervention affects the processes of quitting and maintaining abstinence in Chinese and Vietnamese smokers.

Outcome Measures

Primary Outcomes (4)

  • long-term 7-day point prevalence smoking abstinence (smoker participants)

    Salivary cotinine will be obtained to provide biochemical verification for participants who report abstinence. A cotinine level of \< 12 ng/mL will be considered to verify abstinence. Since nicotine replacement therapy (NRT) use will also produce positive cotinine assays, for participants reporting concurrent NRT use, we will use independent corroboration from family member in lieu of salivary cotinine verification. At Month 12, salivary cotinine will be used for biochemical validation of all smokers reporting abstinence.

    12 months

  • number of 24-hour quit attempts (smoker participants)

    self-report of making quit attempts that lasted at least for 24 hours since baseline

    12 months

  • use of smoking cessation resources since program initiation (smoker participants)

    Use of evidence-based smoking cessation resources since program initiation

    12 months

  • at least 50% reduction of the amount of cigarettes smoked per day from baseline

Study Arms (2)

Quit Smoking for a Healthy Family

EXPERIMENTAL

The experimental/intervention study arm focuses on providing smoking cessation education and support through 2 LHW outreach small group educational sessions (4-5 weeks apart) and 2 individual follow-up telephone calls to smoker and family participants separately.

Behavioral: Quit Smoking for a Healthy Family

Healthy Living

ACTIVE COMPARATOR

In this comparison arm, participants will receive the same number of contacts on the same schedule and in the same format (2 small group sessions and 2 telephone calls). The comparison LHWs will receive training about "Healthy Living" focusing on nutrition and physical activity education. Participants will also receive the Smoking Cessation Resource Handout.

Behavioral: Healthy Living

Interventions

The experimental/intervention study arm focuses on providing smoking cessation education and support through 2 LHW outreach small group educational sessions (4-5 weeks apart) and 2 individual follow-up telephone calls to smoker and family participants separately at 2-3 weeks after each group session for a total of 4 intervention contacts over 2 months. The LHW and dyads will choose the site of sessions, such as the LHW's or a participant's home, or LHW Agency's office. Each small group session will last 90 minutes, be interactive, and involve sharing personal stories, learning using a flip chart, and setting individual goals. Each telephone call will be 15- 20 minutes to reinforce progress and provide support.
