Project Description

Summary

The Multnomah County Drug Testing and Evaluation (DTE) program was established to help clients rid themselves of drug abusing behavior. To that end, the DTE program provided random, weekly drug tests to all clients in the program. These urinalysis tests allowed DTE to monitor each client's compliance with release conditions and progress in treatment programs, and to intervene appropriately when a client showed signs of a drug abuse problem. The DTE program supplemented drug testing with client drug evaluations and treatment recommendations, which were provided to the client's probation officer or case manager. This study was a program evaluation of two of DTE's divisions: the Pretrial Release Supervision Program (PRSP) and the probation and parole program. The pretrial division was chosen because it was the first opportunity for the criminal justice system to supervise and control the drug use of potential DTE clients. The probation and parole program was selected for three reasons: it was the largest component of the DTE program, it linked the pretrial and post-sentence DTE programs, and the experience of this program could be readily applied to the development of other such programs in other jurisdictions. The programs were evaluated using administrative data collected by corrections technicians, case managers, probation and parole officers, and the DTE central office. Part 1 (Pretrial Data) variables include dates of entry into and exit from the program, number of drug tests, number of positive tests for various drugs, type of offense and arrest date for each offense, and need assessment rating for medical, employment, legal, family, psychological, and drug addiction problems. Part 2 (Probation and Parole Data) variables include a probation or parole indicator, prior drug arrests, prior non-drug arrests, prior convictions, technical violations, drug use, and new drug crimes committed during the program. Demographic variables for both files include age, race, and gender.

Methodology

Study Purpose

The Multnomah County Drug Testing and Evaluation (DTE) program was intended to help clients rid themselves of drug abusing behavior. To that end, the DTE program provided random, weekly drug tests to all clients in the program. These drug tests allowed DTE to monitor each client's compliance with release conditions and progress in treatment programs, and to intervene appropriately when a client showed signs of a drug abuse problem. The DTE program supplemented drug testing with client drug evaluations and treatment recommendations, which were provided to the client's probation officer or case manager. This study was a program evaluation of two of DTE's divisions: the Pretrial Release Supervision Program (PRSP) and the probation and parole program. The process evaluation considered seven distinct components of each program: (1) recruitment of clients, (2) drug testing of clients, (3) adjunct client processing, (4) sanctioning and rewarding of clients, (5) client termination or continuation, (6) data communication, storage, and recording among program participants, and (7) linkage of the program to other DTE programs.

Study Design

This study was a process evaluation of two of DTE's divisions: the Pretrial Release Supervision Program (PRSP) and the probation and parole program. The pretrial division was chosen because it was the first opportunity the criminal justice system had to supervise and control the drug use of potential DTE clients. The probation and parole program was selected for three reasons: it was the largest component of the DTE program, it linked the pretrial and post-sentence DTE programs, and the experience of this program could be readily applied to the development of other such programs in other jurisdictions. The programs were evaluated using administrative data collected by corrections technicians, case managers, probation and parole officers, and the DTE central office.

Version History

2005-11-04 On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions.

2006-03-30 File CB2589.ALL.PDF was removed from any previous datasets and flagged as a study-level file, so that it will accompany all downloads.

2000-10-27 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
