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:
1. Participants receiving the experimental intervention will be more likely to achieve at
least a 50% reduction from baseline at 3-month (end of treatment), 6- and 12-month
follow-up than participants in the control condition.
2. Participants receiving the experimental intervention will be more likely to report a
24- hour quit attempt at 3-, 6- and 12-month follow-up.
3. Participants receiving the experimental intervention will be report a longer length of
abstinence in their quit attempts at 3-, 6- and 12-month follow-up.
4. The experimental condition will yield a higher rate of smoking abstinence at 3-, 6- and
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.
