The purpose of this study is to evaluate two brief, sustainable interventions for a sample of 280 adolescents charged with an initial drug-related offense: Motivational Enhancement Therapy (MET) intervention for youth and the Parenting Wisely (PW) intervention for parents. Families are assessed for adolescent substance use, HIV-risk, recidivist substance-related offenses, treatment entry, and other areas of individual and family functioning.

It is expected that the combined MET+PW interventions will be more effective than a treatment-as-usual intervention (drug education group) for adolescents with parents not participating in PW.

Illicit substance use and related problems among adolescents has been consistently high over the past decade and remains one of the most pressing public health concerns in the United States. The objective of this study is to conduct a pilot investigation of the feasibility and effectiveness of two brief empirically based treatments for adolescent substance abuse when implemented as early interventions for youth arrested and charged with first- or second-offense possession of alcohol or drugs. The two examined interventions are Motivational Enhancement therapy (MET) and Parenting Wisely (PW).

Over a one-year period, 280 adolescents and their parents will be referred to the study by the Juvenile Justice Centers in two Oregon counties within the Portland metro area. Families will be randomized to one of four intervention conditions; youth will receive either MET or a drug education intervention (EDUC), and the PW intervention for parents is present or absent. Participants will be assessed for adolescent substance use, HIV-risk, recidivist substance-related offenses, treatment entry, and other areas of individual and family functioning at intake and at 3- and 6-month follow-ups.
