The relationship between pre-, during-, post-treatment factors, and adolescent substance abuse behaviors

FRANÇAIS :
Cet article examine les relations entre les variables d'avant traitement (les caractéristiques psychosociales et familiales, l'abus de substance et les événements particuliers), de durant le traitement (durée de séjour, participation parentale) et d'après traitement (fréquentation de soins de post-cure par les patients et les parents), et les résultats du traitement (suivi à 6 et 12 mois) pour 2317 adolescents. Il apparaît que les variables durant et après traitement permettraient d'identifier le statut d'abstinence à 6 et 12 mois après le traitement. Les variables après traitement semblent offrir la meilleure précision de classification. Malgré ses limites, l'étude indique que les soins de post-cure sont des facteurs importants dans la guérison des adolescents.
ENGLISH :
This study examines the relationships between pre-, during-, posttreatment variables, and treatment outcome by using a secondary data analysis of the 6- and 12-month post-treatment follow-up data from 2317 adolescent subjects. Pre-treatment variables included in this study are psychosocial, family-related, substance abuse, and special event variables. During-treatment variables are length of stay and parental participation in treatment. Post-treatment variables cover the attendance of subsequent treatment/continuing care, such as AA/NA and CD aftercare, and parental attendance of subsequent treatment. Results from discriminant function analyses indicated that duringand post-treatment variables could differentiate the abstinence status at 6- and 12-month follow-ups. It was also shown that the post-treatment variable group exhibited the best classification accuracy among the three variable groups across both follow-up periods. Limitations in applying research findings and their implications for adolescent substance abuse treatment are also discussed. (Authors' abstract)
