NCT01093898

Brief Summary

This study will measure the brain activity of adolescent substance abusers while they make decisions about their preferences to receive smaller, immediate rewards versus larger delayed rewards. The investigators expect that patterns of brain activity while engaged in this decision making task will predict response to treatment among adolescent substance users. The investigators expect to use the results of this study to develop more effective treatments for adolescent substance abuse
