Criminal Justice Drug Abuse Treatment Studies (CJ-DATS): National Criminal Justice Treatment Practices (NCJTP) Survey of Co-occurring Substance Use and Mental Disorder (COD) Treatment Services in Criminal Justice Settings, 2002-2008 (ICPSR 27962)
Principal Investigator(s): Melnick, Gerald, NDRI Rocky Mountains
A growing number of individuals in the criminal justice system suffer from co-occurring disorders (COD), the condition of simultaneous substance and mental disorders. As of yet, the population comprised of these individuals has not been thoroughly studied, despite the fact that COD-afflicted individuals pose unique clinical and administrative problems. The National Criminal Justice Treatment Practices (NCJTP) Survey of Co-occurring Substance Use and Mental Disorder (COD) Treatment Facilities in Criminal Justice Settings attempts to address the lack of information regarding the facets of COD in the criminal justice system. Data collected through this survey was subjected to statistical methods in order to analyze the relationship between COD treatment and organizational aspects. Specifically, from each treatment program, the survey collected data on the number of program participants, proportion of participants with various mental disorders, specific disorder screening instruments used, etc. As for the administrative aspect, the survey determined the division of COD treatment (e.g. one clinician providing both substance abuse and mental disorder treatment versus separate clinicians providing treatment), administrators' opinions of the differences between COD and non-COD participants, and accreditations held by the treatment program.
These data are freely available.

Scope of Study
Geographic Coverage: United States
Unit of Observation: individuals
Universe: The criminal justice, mental health, and substance abuse treatment systems.
Data Types: administrative records data, survey data
Data Collection Notes:
A collaborating research center for this study is CJ-DATS Coordinating Center.
Study Purpose: The purpose of the COD study was to gather information regarding the services provided by the criminal justice system to individuals with COD (co-occurring disorders). Specifically, researchers had three main goals: to describe the services available to individuals with COD, to illustrate the organizational practices of agencies providing these services, and to examine the relationship between service provision and organizational practices.
Study Design: The study created the National Criminal Justice Treatment Practices Survey of Co-Occurring Disorders Treatment Facilities in Criminal Justice Settings, or NCJTP-COD, an addendum to the parent NCJTP survey. The study gathered data regarding organizational practices directly from the NCJTP. Sample subjects were also chosen from the NCJTP, and data collection proceeded according to NCJTP standards. Descriptive statistics were used in analysis of COD service delivery and organizational practices.
Sample: The study sample was comprised of correctional and treatment directors and administrators in criminal justice and community-based settings that had been included in the NCJTP Survey 3. Such subjects are designated Survey 3-level respondents. More specifically, wardens/directors of prisons and jails, administrators in charge for probation and parole offices, and directors of outpatient substance abuse treatment programs were included in the sample. The sample size was 1,046: 208 prisons and juvenile facilities, 436 local corrections entities, 159 directors of substance abuse treatment in prisons/juvenile detention centers, and 243 community-based substance abuse treatment facilities. A detailed description of the NCJTP (and thus NCJTP-COD) sampling procedure can be found in the study manual.
Weight: For Weight information please refer to the Study Data Manual.
Mode of Data Collection: paper and pencil interview (PAPI)
Response Rates: Total response rate of 61.9 percent. For a more detailed breakdown across different treatment programs, please refer to the study manual.
Extent of Processing: 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:
- Standardized missing values.
- Created online analysis version with question text.
- Performed recodes and/or calculated derived variables.
