Brief Summary:
Smoking is widely accepted to cause an increase in an individual's likelihood of developing cancer and heart disease. The effects of tobacco smoke are not limited to smokers. Secondhand smoke inhaled by a non-smoker has also been associated with the development of several illnesses. This study focuses on learning how to make your home smoke-free.

Condition or disease Intervention/treatment Phase
Smoking Cessation Tobacco Cessation Behavioral: Brochure Behavioral: Counseling Not Applicable

Detailed Description:

This study will be conducted in two phases. Phase 1 will be qualitative focus groups/pilot study with the purpose to develop a motivationally enhanced biomarker feedback counseling protocol and all printed materials to be used in Phase 2. After investigators develop a good working treatment protocol, an active intervention in smoking homes who live with a child in their home will be carried out.

Those randomized to the Control Group will receive health education in the form of brochures detailing the health effects of secondhand smoke and how to make their home smoke free. Participants randomized to the Treatment Group will receive tobacco-specific biomarker feedback and personalized motivationally enhanced counseling.

Arm Intervention/treatment
Active Comparator: Control Group - Health Education
This group is provided with information regarding secondhand smoke and creating a healthy home environment.
Behavioral: Brochure
Information regarding secondhand smoke and creating a healthy home environment.

Active Comparator: Treatment Group - Counseling
This group is provided with biomarker feedback on child exposure to secondhand smoke. Active participants receive 5 counseling sessions from a trained research counselor; 3 sessions in the home and 2 by phone. The counseling sessions focus on changing smoking behaviors and/or other behaviors that impact smoking.
Behavioral: Counseling
Receives brochure and counseling sessions focusing on changing smoking behaviors and/or other health behaviors.

Primary Outcome Measures :
  1. Change in Home Secondhand Smoke levels [ Time Frame: From Baseline to Week 26 Follow-Up ]
    Measured by nicotine dosimeter - a passive "badge" hung in the home that measures free floating airborne nicotine particles.

Secondary Outcome Measures :
  1. Comparison of Child Cotinine Levels in Urine [ Time Frame: From Baseline to Week 26 Follow-Up ]
    Cotinine is an alkaloid found in tobacco and is also a metabolite of nicotine. Cotinine is used as a biomarker for exposure to tobacco smoke. Child (non-smoker) cotinine will be used as an objective measure of secondhand smoke exposure at baseline and again at end of study (week 26).

  2. Comparison of Questionnaire Results [ Time Frame: Baseline, Week 16 and Week 26 ]
    Measured by mediators and moderators of effect, including psychosocial and tobacco-related variables.
