Early therapeutic alliance as a predictor of treatment outcome for adolescent cannabis users in outpatient treatment.

The association of early alliance to treatment attendance and longitudinal outcomes were examined in 356 adolescents participating in a randomized clinical trial targeting cannabis use. Both patient and therapist views of alliance were examined, and outcomes were evaluated over 12 months after numerous other sources of variance were controlled. Patient-rated alliance predicted a reduction in cannabis use at three and six months and a reduction in substance-related problem behaviors at six months.

The Cannabis Youth Treatment (CYT) Study: main findings from two randomized trials.

This article presents the main outcome findings from two inter-related randomized trials conducted at four sites to evaluate the effectiveness and cost-effectiveness of five short-term outpatient interventions for adolescents with cannabis use disorders. Trial 1 compared five sessions of Motivational Enhancement Therapy plus Cognitive Behavioral Therapy (MET/CBT) with a 12-session regimen of MET and CBT (MET/CBT12) and another that included family education and therapy components (Family Support Network [FSN]). Trial II compared the five-session MET/CBT with the Adolescent Community Reinforcement Approach (ACRA) and Multidimensional Family Therapy (MDFT).

Gender differences in substance use, mental health, and criminal justice involvement of adolescents at treatment entry and at three, six, twelve and thirty month follow-up.

Many adolescents entering substance abuse treatment have coexisting mental health problems and are criminally involved. Examination of the complexities of substance use, mental health, and criminal justice involvement along with changes in these issues following treatment is needed. This study includes 941 males and 266 females enrolled in seven drug treatment programs located in geographically diverse areas of the United States.

Outpatient marijuana treatment for adolescents. Economic evaluation of a multisite field experiment.

An economic evaluation of five outpatient adolescent treatment approaches (12 total site-by-conditions) was conducted. The economic cost of each of the 12 site-specific treatment conditions was determined by the Drug Abuse Treatment Cost Analysis Program (DATCAP). Economic benefits of treatment were estimated by first monetizing a series of treatment outcomes and then analyzing the magnitude of these monetized outcomes from baseline through the 12-month follow-up.

Cannabis use: consistency and validity of self-report, on-site urine testing and laboratory testing.

Aims: To evaluate the agreement between adolescent self-reported cannabis use, "on-site" qualitative urine screening, and quantitative laboratory testing.

Design: A cross-sectional study of intake and follow-up data from 248 adolescents entering substance abuse treatment for cannabis use disorders (abuse or dependence). This is part of the multi-site cooperative agreement Cannabis Youth Treatment study.
