This study examined program outcomes for 133 graduates (46.2%) and 155 terminated clients (53.8%) of an adult felony drug court in Salt Lake City, Utah, in an effort to identify factors that predict program completion and drop out. Logistic regression analyses identified three factors related to drop out: depression, cocaine/stimulants as most troubling substance, and additional charges prior to drug court intake. Two factors were found to be related to completion: spending free time with family rather than with friends or alone and older age at intake. The model correctly predicted 65% of graduates and 73% of dropouts. These findings are discussed with respect to their implications for policy, practice, and future research.
