It's an optimum length--16 weeks*--for intensive outpatient treatment. Opportunity for successful outcome is increased when the client has a protracted engagement in treatment plan.

*The Matrix Model treatment protocol can be extended up to 12 months through continuing care/aftercare.

It's structured differently than inpatient treatment, using methods proven-effective with stimulant addicts

• It's less confrontational
• Progress is gradual
• The focus is on the present
• "Core issues" are not immediately addressed
• The client's allegiance is to the therapist rather than the group
• A non-judgmental attitude is basis of client-therapist bond
• Change recommendations are based on scientific data
• Changes are incorporated immediately into lifestyle

It's more directive and behavior-focused than general therapy

• Visit frequency results in strong transference, which is encouraged and utilized
• Goal is stability versus comfort
• Focus is abstinence; bottom-line is always continued abstinence
• Therapeutic team approach is utilized
• Therapist frequently pursues less motivated clients
• Focus is on behavior rather than feelings; the behavior is more important than the reason behind it
• Family system support is encouraged
• Therapist functions as a coach/advocate

It's proven-effective. The organizing principles of the Matrix have been developed and modified over a 20 year period, using data from the treatment experience of 6,000 cocaine and 2,500 methamphetamine addicts. The Matrix Model works because it

• Creates explicit structure and expectations
• Establishes a positive, collaborative relationship with each patient
• Teaches information and cognitive-behavioral concepts
• Positively reinforces positive behavior change
• Provides corrective feedback when necessary/roll with resistance
• Educates family regarding stimulant abuse recovery
• Introduces and encourages self-help participation
• Uses urinalysis to monitor drug use and take the issue of use "off the table"

It's evidence-based. The Matrix Model has over 20 years of research and development, and was recently tested in the CSAT Methamphetamine Project, the largest randomized clinical trial of treatment of methamphetamine addiction to date. Clients assigned to the Matrix Model:

• Attended more groups
• Stayed in treatment longer
• Provided more methamphetamine-free urine samples during treatment
• Had longer periods of methamphetamine abstinence
