Brief Summary

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:

  1. 1.Examine the effectiveness of proactive recruitment of Chinese smokers into a smoking cessation treatment program through their family or friends.
  2. 2.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.
  3. 3.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.
