The Consortium will investigate and model client characteristics that predict treatment success. The project consists of four steps:

• A literature review to identify evaluate predictors of treatment success.
• An analysis of existing data using Iowa's substance abuse reporting system (SARS) to create a statistical prediction model of success.
• A review of the model with substance abuse treatment agency directors and Iowa Department of Public Health officials.
• Develop suggestions for future data collection and improvements in the SARS.
