 The primary goal of the Hutchinson Study of High School Smoking, a group-randomized trial conducted by the Fred Hutchinson Cancer Research Center in partnership with 50 Washington State high schools, is to develop and evaluate an innovative proactive smoking cessation intervention, based upon Motivational Interviewing MI and Cognitive Behavioral Skills Training CBST, for its effectiveness in reaching teen smokers and helping them succeed in quitting smoking. A positive finding would have significant implications for reducing youth smoking and, ultimately, improving the nations health.
