Research Evaluation
2Defining Recidivism
- Felony adjudication (conviction) within 3 years
of release from closed custody or commitment to
probation.
3Defining the Assessments
- ORRA OYA Recidivism Risk Assessment. Identifies
the likelihood a youth will recidivate after
release from closed custody or commitment to
probation. - ORRA-V OYA Recidivism Risk AssessmentViolent.
Identifies the likelihood a youth will VIOLENTLY
recidivate after release from closed custody or
commitment to probation. Recognizes the
propensity for violence or threatening crimes
that may result in physical harm.
4Why Develop a Risk Assessment
- Program evaluation
- Placement and treatment decisions
- Parole Decisions
- Sentencing practices
- RNA fails to differentiate risk populations
- Poor predictive accuracy
5 The Data
- 15,968 total youth
- Date range of population January 2005 to May 2007
- Four Youth Populations
- County Probation
- Committed to OYA Probation
- Released from OYA Close Custody Facility
- Released from OYA Close Custody Facility to
Supervision in the adult system
6Dozens of Variables were Considered

- Total prior sex offense referrals
- Total prior felony referrals

7Dozens of Variables were Considered (cont.)

11Interpreting Scores
- Each youth has a score between 0 and 100
- The score approximates the probability that the
youth will recidivate - For example, a youth with a score of 40 has a
40 probability they will recidivate - This also means the youth has a 60 approximate
score that the youth will NOT recidivate.
12Model Accuracy
- Overall Accuracy for ORRA 73
- Accurate for all subpopulations
- Accuracy of 50 suggests poor predictive accuracy
- Accuracy of 100 suggests perfect predictive
accuracy
13Comparison of the Four Populations
14Differences in Youth Populations
15Predictive Accuracy
16Interpreting Scores
- ORRA and ORRA-V scores can also be evaluated for
a specific population - The average score for a group of youth estimates
the expected recidivism rate for the group

in numerous non-violent incidents in the first
six months of closed custody

30 Type A Description
- Highest need population
- AOD use is high both current and historical
- Poor relationships and likely lack relationship
skills - Highest on aggression and attitude issues
- History of Mental Health ADD/ADHD or mental
health diagnosis recommend analysis of RNA
items 15.5 and 15.6 to differentiate ADD/ADHD
versus Formal MH Diagnosis - Education issues are prominent recommend
analysis of RNA item 3.1 for potential
responsivity issues - 3.1 Special Education or Formal Diagnosis of
Special Education Need (LD, SED, MRDD Indicators)
31Treatment Recommendation
- Estimated to require longest dosage of treatment
(e.g., 12-18 months) - Group may require more stabilization than other
groups due to co-occurring mental health and
learning concerns - AOD Treatment (longer in duration due to
persistency) - MH treatment with QMHP
- Educational intervention
- Social Skills/Relationship Skills development
(intensive) - Engagement in prosocial activities that can
foster protective factors - Potential family therapy component
- Aggression Replacement Training (intensive)
- Cognitive Behavioral program to address thinking
32 Type E Description
- 66 of this cluster is SO
- Highest on protective factors
- Low need for MH ADD/ADHD or mental health
diagnosis recommend analysis of RNA items 15.5
and 15.6 to differentiate ADD/ADHD versus Formal
MH Diagnosis - Education issues are low recommend analysis of
RNA item 3.1 for potential responsivity issues - 3.1 Special Education or Formal Diagnosis of
Special Education Need (LD, SED, MRDD Indicators)
33Treatment Recommendations (Type E)
- Sex Offender Treatment when appropriate
(Abbreviated Kaufman or general cognitive
behavioral treatment) - Capitalize on whatever activities youth engaged
in prior to coming as leverage for treatment
engagement - Seek opportunities for continued engagement
34Optimal Length of Stay
- Calculated length of stay in months
- Plotted LOS against recidivism for the overall
sample - On average, providers reduce recidivism by
approximately 3 per month of supervision - But, there may be a window of time where
providers are most effective

49What for
- Interpreting ORRA Scores
- Each youth get a score between 0 and 1
- The score represents the probability that the
youth will recidivate - For example, a youth with a score of .42 has a
42 probability they will recidivate - The average score for a group of youth estimates
the expected recidivism rate for the group - For example, the average ORRA score for females
on OYA probation was 13.1 and the actual
recidivism rate was 13.0.
50What for
- ORRA has multiple uses
- Placement and treatment decisions
- Parole decisions
- Program evaluations
- Sentencing practices
- Foundation for future improvement in risk
assessment
51- What for
- Making comparisons while controlling for risk
52- What for
- Making comparisons while controlling for risk
53- What for
- Making comparisons while controlling for risk
54Other risk equations
- ORRA
- ORRA-V
- Risk of being involved in a violent incident in
the first year in OYA close custody
55Implementing ORRA ScoresAn Example
- Used ORRA Scores in Evaluating the Effectiveness
of Residential Programs - Is the actual recidivism rate different than the
predicted recidivism rate? - Is there an optimal length of stay?
- With which youth is a program most effective?
- All youth in residential programs from 2000 to
2007 - Used official OYA definition for recidivism

57Next step? Right YouthRight Program
- In depth analysis about who programs are most
effective with - Potential variables include sex, age, offense
type - In addition to understanding which youth are most
effectively served by a specific program, this
analysis may identify gaps and determine which
youth are not served well by current provider
resources
