The 1997 survey, an expansion of previous drug court surveys, consisted of six sections to be completed by the principal agencies involved in the drug court operations in each of the jurisdictions surveyed. The six sections pertained to general program information to be completed by the court and more specific information that related to prosecution activities; defense activities; law enforcement activities; correctional agency activities; and the treatment, rehabilitation, and related services provided for the program. Volume I contains general program information provided primarily by drug court judges and judicial staff. Volume II provides information that relates to the activities and perspectives of prosecutors, public defenders, law enforcement officials, and correctional agency administrators involved with drug courts in their local jurisdictions. Volume III focuses on the treatment and rehabilitation services provided for drug courts programs and reflects the comments of treatment professionals who provide services to drug courts in their respective jurisdictions. Volume IV provides the perspectives of 256 participants in the final phases of 53 drug court programs in 23 States and the District of Columbia regarding critical aspects of drug court program operations.
