In this study, we choose to specifically recruit Chinese, the largest ethnic group of the Asian and Pacific Islander community,2 as an initial step to increase our understanding of the role of family or supportive others in the process of smoking cessation among Asian Americans. We propose the following specific aims for the study:
- Examine the effectiveness of proactive recruitment of Chinese smokers into a smoking cessation treatment program through their family or friends.
- Test the efficacy of a family assisted intervention using the stages of change approach in promoting smoking cessation in the context of an expert system intervention.
- Explore the role of supportive and non-supportive behaviors in relation to both short-term and long-term smoking cessation outcomes in the presence of the expert system intervention.

Active Comparator: 1
Expert system (stage-based manual and 3 individualized tailored feedback reports) only for smokers, paired-supporters (family or friend participant) do not receive any study intervention
Behavioral: Expert System Only
expert system intervention only to the smoker participants which includes a stage-based manual and a series of 3 individualized tailored feedback report at baseline, 3, and 6 months. The paired-supporters receive assessments only and no intervention.
Expert system (stage-based manual and 3 individualized tailored feedback report) to all the smoker participants; a family assisted intervention in a form of a self-help booklet that discusses specific strategies to work with smokers at each stage of change to the paired-supporters
Behavioral: Family Assisted
The smoker participants received an expert system intervention (same intervention for those in the Expert system intervention) which includes a stage-based manual and a series of 3 individualized tailored feedback report at baseline, 3, and 6 months. The paired-supporters will receive a a self-help booklet based on the Transtheoretical Model of Change (TTM) that will aim at teaching the supporters how to use the stages of change framework to apply different strategies that best match with smokers' readiness to quit smoking.
