The purpose of this study is to test the effects of a computerized, self-directed Motivational Enhancement Therapy program for adolescent substance use (iMET), in comparison to clinician-delivered MET and Treatment As Usual (TAU), on treatment engagement and substance use. The investigators hypothesize that both iMET and MET will be more effective than TAU in engaging/retaining patients in treatment and in reducing substance use during a 12-month follow-up period. The investigators also hypothesize that Self-directed iMET will be as effective as the clinician-guided MET in increasing treatment engagement and abstinence during the 12-months follow-up period.

Further study details as provided by Children's Hospital Boston:

Primary Outcome Measures:
  • Treatment engagement [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    We will compare the number of individual visits in the program, the number of group sessions completed, and the number of urine screens completed during a 12 month follow-up period by each participant in the three study arms.

Secondary Outcome Measures:
  • Days abstinent [ Time Frame: past-90-days ] [ Designated as safety issue: No ]
    We will calculate the past-90-days number of days abstinent from any substance use and from the primary substance and the number of weeks abstinent from any substance use.

  • Driving/Riding Risk [ Time Frame: past-90-days ] [ Designated as safety issue: Yes ]
    We will compare group trends in prevalence and frequency of past-90-days Driving while impaired or Riding with an impaired driver.

  • HIV Risk Behavior [ Time Frame: past-90-days ] [ Designated as safety issue: No ]
    We will compare group trends in prevalence and frequency of past-90-days HIV Risk Behaviors.

Other Outcome Measures:
  • Treatment process/quality [ Time Frame: 60 days ] [ Designated as safety issue: No ]
    We will compare completion of the 2 MET sessions, and completion of the third follow-up visit between the iMET and MET conditions.
