The Chemical Dependency Disposition Alternative (CDDA) was created by the 1997 Washington State Legislature as a sentencing option for juvenile offenders. The goal was to reduce recidivism by providing treatment for chemically dependent or substance abusing youth. The Institute was directed by the 1997 Legislature to evaluate CDDA to determine its impacts on recidivism. The Institute surveyed the courts to determine how to identify both the CDDA and the CDDA comparison groups. After the initial phase of data collection, the Institute found that an appropriate comparison group could not be identified. Thus, it was not possible to evaluate the impact of CDDA on recidivism or conduct a cost-benefit analysis. However, the survey revealed variations in the implementation of CDDA across the state.
