Interactive Computer Tailored Smoking Cessation and Prevention for Adolescents.

Computer tailored interventions have been proven to be successful in smoking cessation and prevention among adults and young adolescents. This study investigates the effectiveness of a computer tailored smoking cessation and prevention intervention for 15-17 year old adolescents. Participants in the study fill out a questionnaire on the Internet three ties within a year. One third of the participants receive a personalized advice on the Internet about smoking (cessation) immediately after filling out the questionnaire. A second group receives a personalized advice per letter and a third group receives no advice at all. Smoking status as well as cognitive factors related to smoking (cessation) and demographic variables will be assessed. The two experimental groups receive three times personalized information on the smoking behavior within the 6 months between first and second measurement. To assess long-term effects of the intervention a 12-month post test are held.

Intervention lead to 5% less smoking uptake and 10% more quit attempts.
