CJ-DATS Phase I Studies - Assessing Offender Problems

Revised January 2013

Inmate Pre-Release Assessment (IPASS)

PI: Michael Prendergast, Ph.D. (U01DA016211)

Although at least two valid assessments previously existed to inform decisions regarding level of supervision for paroling offenders (e.g., Level of Services Inventory) or modality of treatment for substance abusers in the community (e.g., ASAM criteria), neither of these assessments was developed specifically for substance-abusing parolees who are encouraged or required to participate in treatment after they are released from prison.  IPASS was developed specifically as a post-release risk measure for prison-based substance abuse treatment graduates by taking into account the inmates’ historical drug use and criminal activity as well as his or her performance during the prison-based treatment program. 

The primary purpose of this study was to:

  • Test the ability of the IPASS to predict relapse and recidivism using a prospective design.
  • Assess its use in matching offenders to a particular level of aftercare

Criminal Justice Co-Occurring Disorder Screening Instrument (CJ-CODSI)

PI: Stanley Sacks, Ph.D. (RC2DA028967)

An understanding of the presence and extent of co-occurring disorders (co-existing substance use and mental disorders, of COD) is essential to improving the design of COD programming, both in prison and upon release.  The measures currently employed in criminal justice programs, particularly those developed to screen for mental health disorder, typically focus on mental disorders or substance abuse disorders separately, and fail to examine the extent to which these disorders co-exist in the criminal justice population.

This 12-month research project aimed to:

  • Develop a brief screening instrument that identifies individuals with COD in 20 minutes or less and that could be self-administered or administered by staff who do not have mental health training. 
  • Assess the feasibility of using the instrument to determine rates of COD in the offender population by conducting a study of 300 consecutive admissions to prison-based substance abuse treatment programs at selected sites.
