This report presents methodology and findings from the Uniform Facility Data Set (UFDS) 1997 Survey of Correctional Facilities, which surveyed about 7,600 adult and juvenile correctional facilities to identify those that provide on-site substance abuse treatment to their inmates or residents. The survey assesses substance abuse treatment provided within the nation's Federal prisons, state prisons, jails, and public and private juvenile facilities. The report has eight sections and three appendixes. Following the introduction, Sections 2 and 3 present the background and reasons for conducting the UFDS 1997 Survey of Correctional Facilities; the survey methodology; the development and the pilot testing of the survey instrument; the data collection and response rate; and the terminology and definitions used in the report. The main findings from the survey are presented in sections 4 through 8. Section 4 includes an enumeration of facilities providing supplemental non-treatment substance abuse services by facility type (Federal prison, state prison, jail, or juvenile facility), the number of facilities providing treatment by treatment setting (specialty substance abuse treatment unit, treatment in the general inmate population, or treatment in hospital inpatient/psychiatric units), and the number of facilities providing treatment by type of counseling (individual counseling, group counseling, or family counseling). Sections 5 through 8 focus on more detailed data for Federal prisons, state prisons, jails, and juvenile facilities, respectively. (Contains 30 tables and 3 appendixes.) (GCP)
