Risk Assessment Facts, Myths and Trends James Austin, Ph.D. 2008
The Need to Manage Risk • Public Safety – Reduce Recidivism Rates and Allows for Better Investments • Increases Credibility with the Public and Legislature • Reduces the potential for disproportionate use of incarceration by Gender, Race and Ethnicity • Better use of public resources
The Key Decision Points • 1. Initial Parole Eligibility Hearing • a. Parole • b. Continue (why and for how long) • c. “Serve All” • 2. Rehearing (more of the initial hearing) • 3. Mandatory Parole • 4. Imposition of Supervision Conditions • 5. Parole Revocation • a. Detain or Release • b. Period of Incarceration

Key Concepts in The Prediction of Risk • Variance • Probabilities • Independent Variables – The Predictors 4. Dependent Variable – What We Are Trying to Predict • Static Predictors – Things That Do Not Change 6. Dynamic Predictors – Things That Do Change
Variance in Life Chances of Being Imprisoned in USA1974-2001

Crime and Welfare 1931-2003 7,000.0 16,000.0 14,000.0 6,000.0 12,000.0 5,000.0 10,000.0 4,000.0 Crime Rate Welfare Recipients 8,000.0 3,000.0 6,000.0 2,000.0 4,000.0 1,000.0 2,000.0 0.0 0.0 Year
More Key Concepts on Risk • Measurement Error • Triangulation (Multiple Sources) • Public Records • Interviews • Questionnaires • Observation • Reliability • Inter-Reliability (Do we all do it the same way) • Intra-Reliability (Do I do it the same way) • Validity • Internal Validity (does it work in my place) • External Validy (does it also work in other places)
Still More Concepts • An Instrument Can Be Reliable but Not Valid • An Instrument Cannot Be Unreliable and Valid • False Positives (should have recidivated but did not) • False Negatives (should have not recidivated but did) • Multi-collinearity (independent predictors)
And More Concepts • Clinical Judgments Alone Are In-Effective in Predicting Risk • Statistical Models Are Effective In Predicting General Recidivism • Statistical Models Are In-Effective in Predicting “Rare Events” • Violent Crimes • Career Criminals • Sex Crimes • The Problem of “Low” Base Rates
Current State of Risk Assessment • There is no superior or better risk assessment instrument or system • There are commercial and public risk systems that can work • The differences are in costs and staff skill requirements • Few states have risk assessment systems that have been properly developed and implemented • Lack of reliability and validity
Some Basics About Criminal Behavior • Criminal Behavior (Like Other Behavior) Is Learned • Criminal Careers Have Starting And Ending Points • Most Criminal Behavior is Episodic in Nature • Very Few “Criminals” Are Career Criminals • Places and Other People Impact Behavior
What About Treatment? • Good treatment in prison is rare 2. The “market share” problem 3. Most one can expect is 10% reduction in the expected recidivism rate • Education and vocational training should be priorities 5. Wrong Use of Treatment Increases Risk
Percent of Arrests Attributed to Released Prisoners Type of arrests N % Total Arrests in Seven States 1994-97 2,994,868 100% Arrests of Prison Releases 1994-97 140,534 5% Percent that are Violent Crimes 36,000 1%
Key Points About Offender Risk Prisoners are slowing down or ending their criminal activities Probation versus prison is slightly more effective Extending or reducing prison terms is not related to recidivism Extending or Reducing parole/probation supervision is not related to recidivism Prisoners who “max out” do better than those paroled Small Percent (5%-10%) of all crimes are committed to persons released from prison. Very small % of released prisoners are re-arrested for murder or rape (less than 1%) and very small % of released murders or rapists are re-arrested for these crimes (under 2%). Treatment for Low Risk Persons Increases Recidivism while treatment for high risk persons reduces recidivism

Do’s and Don’ts • Must Be Tested On the Your Correctional Population • Must Conduct Objective and Independent Inter-Reliability and Validity Tests • Must Allow for Dynamic and Static Factors that Have Been Well Accepted and Tested in a Number of Jurisdictions • Must Be Compatible With the Staff’s Skill Level • Must Be an Opportunity to Depart from Scored Risk Levels Based on a System of Structured Clinical Judgments • Must Have “Face Validity” with Staff, Offenders and Policy Makers
Strategic Steps for Building Risk Assessment Instrument Agree on the Need for Risk Assessment Conduct Recidivism Study of Released Prisoners Build Risk Instrument Based on Recidivism Conduct Reliability Study Finalize Risk Instrument Implement/Monitor
Summary Points • You cannot afford not to use risk assessment in release and supervision decisions • Not using risk assessment worsens public safety • Key Areas of Concern • Imposition of treatment and conditions to low risk prisoners • Excessive periods of supervision (more than 12 months) • Re-incarceration for non-criminal behavior or misdemeanor crimes • Excessive periods of confinement – the diminishing return problem • The release decision • The revocation decision • The lack of information and its contribution to mythology • DUIs • Sex Offenders • Public safety • Gender and Racial Bias
