For clients with more severe substance abuse problems, clients in this treatment attend two groups per week. The groups focus on both psycho-education and process therapy. The psycho-education components are taken from Phase I of Strategies for Self-Improvement and Change, developed in Denver by Kenneth Wanberg and Harvey Milkman. Clients attend group twice weekly for a minimum of 12 weeks, followed by 24 weeks of once weekly groups. Once they have successfully completed the minimum 36 weeks of EOP treatment, the clients will be stepped down into a lower level of care.
