Résumé :
FRANÇAIS :
Cette étude compare le modèle Matrix, approche multidisiplinaire, à un traitement standard dans la prise en charge des usagers d'amphétamines. De 1999 à 2001, 978 usagers à la recherche de traitement ont été assignés à un traitement standard ou au traitement sur le modèle Matrix. Pendant la période de traitement, l'efficacité du modèle est largement démontrée en terme de suivi du traitement, de rétention et d'abstinence. Mais les résultats lors des contrôles en fin de traitement ou lors du suivi 6 mois après ne montrent pas une supériorité de par rapport au traitement standard.

Aims: The Center for Substance Abuse Treatment (CSAT) Methamphetamine Treatment Project (MTP) is the largest randomized clinical trial of treatments for methamphetamine (MA) dependence to date. The objective of the study was to compare the Matrix Model, a manualized treatment method, with treatment-as-usual (TAU) in eight community out-patient settings in the Western United States. Design: Over an 18-month period between 1999 and 2001, 978 treatment-seeking, MA-dependent people were randomly assigned to receive either TAU at each site or a manualized 16-week treatment (Matrix Model). Setting: The study was conducted as an eight-site out-patient trial, with six sites located in California and one each in Montana and Hawaii. Findings: In the overall sample and in the majority of sites, those who were assigned to Matrix treatment attended more clinical sessions, stayed in treatment longer, provided more MA-free urine samples during the treatment period and had longer periods of MA abstinence than those assigned to receive TAU. Measures of drug use and functioning collected at treatment discharge and 6 months post-admission indicate significant improvement by participants in a11 sites and conditions when compared to baseline levels, but the superiority of the Matrix approach did not persist at these two timepoints. Conclusions: Study results demonstrate a significant initial step in documenting the efficacy of the Matrix approach. Although the superiority of the Matrix approach over TAU was not maintained at the post-treatment timepoints, the in-treatment benefit is an important demonstration of empirical support for this psychosocial treatment approach.
