Résumé :
FRANÇAIS :
Etude auprès de 200 jeunes (16-20 ans) des changements de consommation de cigarette, d'alcool, de cannabis et d'autres drogues et de perception des risques 3 mois et 1 an après soit un entretien motivationnel soit un entretien de contrôle classique. Les différences en faveur de l'entretien motivationnel observées à 3 mois ne sont pas perceptibles au bout de 1 an.
ENGLISH:
Aim To test whether beneficial effects of a single session of Motivational Interviewing (MI) on alcohol, tobacco and illicit drug use apparent after 3 months were maintained until 12 months. Design Cluster randomized trial, allocating 200 young people in the natural groups in which they were recruited to either MI (n = 105) or to an assessment-only control condition (n = 95). Setting Ten further education colleges across inner London. Participants Two hundred young people who were current users of illegal drugs (age range 16-20 years) with whom contact was established through peers trained for the project. Intervention The intervention was adapted from MI in the form of a topic-based 1-hour single-session discussion. Measurements Changes in cigarette, alcohol, cannabis and other drug use and perceptions of risk and harm between the time of recruitment and follow-up interviews after 3 and 12 months. Findings A satisfactory follow-up rate (81%) was achieved. After 12 months, 3-month differences between MI and assessment-only groups have disappeared almost entirely. Unexpected improvements by the assessment-only control group on a number of outcomes suggest the possibility of reactivity to the research assessment at 3-month follow-up. Conclusion In the terms of the original experiment, there is little evidence of enduring intervention effectiveness shown by between-group differences after 12 months. Deterioration of effect is the most probable explanation, although reactivity to 3-month assessment, a late Hawthorne effect, cannot be ruled out. (Author' s abstract)
