An interventional study of Expert System Only and Enhanced Expert System in Smoking Cessation, sponsored by University of California, San Francisco. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2013-07-10.

This study aims at developing and testing a stage-based scheduled smoking intervention that targets to encourage smokers to reduce smoking and to facilitate smoking abstinence. We hypothesize that smokers who receive the staged-based scheduled smoking intervention will be more likely to report smoking abstinence, quit attempts, and smoking reduction at 12 months.
The objective of the study is to document and systematically investigate the use of smoking reduction and cessation strategies targeting Chinese American smokers at various level of readiness to quit smoking.
Using a randomized controlled study design, the experimental intervention will be compared to a control group that will receive the expert system intervention only at 3-, 6- and 12-month follow-up. The primary aim is to test the following hypotheses:
The secondary aim is to examine the feasibility of the proposed intervention which will be assessed by recruitment efficiency, refusal rates, adherence, usage, safety data, and perceived helpfulness of the intervention components. In addition, analyses will be pursued to explore both short- and long-term maintenance of smoking reduction achieved, the association between smoking reduction and changes in self-efficacy of resisting from smoking, stage movements (changes in readiness for quitting), and the use of coping strategies for smoking at follow-ups. The study will provide important empirical data for developing effective smoking cessation strategies that are culturally and linguistically appropriate for the Chinese American population.
