Project EX--a teen smoking cessation initial study in Wuhan, China.

The increasing smoking prevalence in China indicates a need for effective smoking cessation programs, yet, to our knowledge, no studies have evaluated the effects of smoking cessation programs among Chinese adolescents. A group of 46 10th-grade-level cigarette smokers from two schools in Wuhan, China, were provided with Project EX, an eight-session school-based clinic smoking cessation program developed in the United States. Efforts of translation of the Project EX curriculum, verification of translation, curriculum modification, and cultural adaptation were made to adapt the curriculum to the local culture. The 46 smokers represented 71% of all the self-reported 30-day smokers among 622 10th graders at these two schools. Only one student dropped out from the clinic program. Four-month follow-up data indicated a 10.5% 30-day quit rate and a 14.3% 7-day quit rate. The students who did not quit smoking reported a 16% reduction in daily cigarette consumption at posttest and a 33% reduction at 4-month follow-up. Use of a 2 1/2-week prebaseline-to-baseline clinic assessment indicated a clinic cohort nonassisted quit rate of 3%. These data provided evidence that Project EX can be adapted in another country, such as China; can be very well received; and can lead to promising results on cessation.

Sensations from initial exposure to nicotine predicting adolescent smoking in China: a potential measure of vulnerability to nicotine.

Sensations derived from initial exposure to nicotine are a potential indicator of an individual's vulnerability to nicotine. This study assessed whether sensations experienced during the first lifetime exposure to nicotine could predict current and established cigarette smoking. Data from 210 respondents who reported having ever tried cigarette smoking in Wuhan, China, were obtained for this study from 610 students in 10th grade at two schools. Subjects were participants in a multipurpose pilot survey for an adolescent smoking prevention trial. The survey was administered in a classroom setting using a paper-and-pencil questionnaire. Sensations reported were cigarette smell (59.2%), coughing (54.1%), dizziness (52.1%), nausea (42.5%), relaxation (19.1%), and pleasurable buzz/rush (9.0%). After controlling for confounders, multiple logistic regression analyses identified three sensations significantly associated with smoking: (a) Cigarette smell (OR for days smoked in the past 30 days=2.93, p<.05, OR for number of cigarettes smoked per day=2.69, p<.05, and OR for 100-cigarette smoking=5.40, p<.01), (b) pleasurable buzz/rush (OR for 100-cigarette smoking=11.09, p<.05), and (c) relaxation (OR for past 30-day smoking measures ranged from 3.69 to 4.48, p<.01, and OR for 100-cigarette smoking=4.12, p<.05). A dose-response relationship was observed between the sensations and cigarette smoking. Self-reported sensations from initial exposure to nicotine may be a useful indicator of an individual's vulnerability to nicotine. This information can be used for adolescent smoking prevention and cessation interventions.

Training the transdisciplinary scientist: a general framework applied to tobacco use behavior.

The complexity of public health problems, including the problem of tobacco use behaviors, calls for formal efforts to train transdisciplinary scientists. These scientists can approach problems by using new conceptual frameworks and methodological tools that integrate different disciplinary perspectives. Transdisciplinary training focuses on developing strong scientists with superb core skills while protecting against creating scientists who are "jack of all trades, master of none." Transdisciplinary training is relatively new, with no accepted training model in place. In this paper, we provide a general framework for transdisciplinary training at the advanced graduate and postgraduate levels, with particular reference to tobacco use behaviors. We identify the core attitude, knowledge, and skills competencies that are essential to conducting tobacco use research with a transdisciplinary approach. We outline the structural components of transdisciplinary training that allow for the development of the competencies and discuss what facilitates the transdisciplinary training process. We also discuss the numerous challenges and obstacles to transdisciplinary training. These include the readiness of early-career trainees to undergo transdisciplinary training, professional development risks taken by trainees, administrative and budgetary obstacles inherent in traditional academic institutional structures, and the limited opportunities established scientists have for transitioning their research programs in a transdisciplinary direction. If these obstacles can be overcome, the potential exists for a new generation of transdisciplinary scientists to be trained and be well positioned to make important and unique advances in our understanding of tobacco use and other public health problems.

Evaluating transdisciplinary science.

The past two decades have seen a growing interest and investment in transdisciplinary research teams and centers. The Transdisciplinary Tobacco Use Research Centers (TTURCs) exemplify large-scale scientific collaborations undertaken for the explicit purpose of promoting novel conceptual and methodological integrations bridging two or more fields. Until recently, few efforts have been made to evaluate the collaborative processes, and the scientific and public policy outcomes, of such centers. This manuscript offers a conceptual framework for understanding and evaluating transdisciplinary science and describes two ongoing evaluation studies covering the initial phase of the TTURC initiative. The methods and measures used by these studies are described, and early evaluative findings from the first 4 years of the initiative are presented. These data reveal progress toward intellectual integration within and between several of the TTURCs, and cumulative changes in the collaborative behaviors and values of participants over the course of the initiative. The data also suggest that different centers may follow alternative pathways toward transdisciplinary integration and highlight certain environmental, organizational, and institutional factors that influence each center's readiness for collaboration. Methodological challenges posed by the complexities of evaluating large-scale scientific collaborations (including those that specifically aspire toward transdisciplinary integrations spanning multiple fields) are discussed. Finally, new directions for future evaluative studies of transdisciplinary scientific collaboration, both within and beyond the field of tobacco science, are described.
