The program was developed by the Colorado Alcohol and Drug Abuse Division in collaboration with the Colorado Division of Youth Services, with funding from the Office of Substance Abuse Prevention. The Integrated Social Psychological Model provided the theoretical basis for the project and integrates elements of strain theory, social control theory, and social learning theory. The project activities are carried out through four phases: assessment, wilderness experience, alternative lifestyle, and community transition. Project clients started using alcohol at age 12.1 years, marijuana at 12.5 years, and cocaine at 14.8 years. The youths had extensive delinquency histories. The evaluation plan for the project involves the documentation of the development of project components, the recording of the implementation of project components and the assessment of the effectiveness of project components.
