Risk assessment instruments form the empirical backbone of modern forensic psychology practice in New Zealand corrections. These validated tools provide structured professional judgment frameworks that help clinical psychologists formulate evidence-based opinions about an offender's risk of reoffending and treatment needs.
Key Takeaways
- RoC*RoI is NZ's primary actuarial tool predicting general reconviction risk
- VRS measures violence risk through static/dynamic factors and stage-of-change scoring
- LS/CMI integrates risk assessment with case management planning
- SAPROF provides a complementary protective factors perspective
- Together, these tools inform comprehensive Section 21 parole risk assessments
"Multi-instrument assessment provides a comprehensive risk profile that satisfies the requirements of Section 21 parole risk assessments while enabling clinically informed treatment planning."
� Precision AOD SolutionsThe Actuarial Foundation: RoC*RoI
The RoC*RoI (Risk of Reconviction/Risk of Imprisonment) is New Zealand's primary actuarial risk prediction tool, developed specifically for the NZ corrections context. Unlike generic international instruments, RoC*RoI was normed on the New Zealand offender population and validated against NZ reconviction data.
RoC*RoI at a Glance
- Type: Actuarial (static factors only)
- Purpose: Predicts 2-year and 5-year reconviction risk
- Variables: Age at first conviction, offense history, gender, ethnicity
- Output: Risk category (Low/Medium/High) with percentile ranking
- Administration: Completed from official records � no client interview required
RoC*RoI scores are derived from static risk factors � historical variables that cannot be changed through intervention:
Static Risk Factors
- Age at first conviction: Earlier first conviction correlates with higher reconviction rates
- Number of prior convictions: More convictions indicate established criminal patterns
- Offense seriousness: More severe historical offending predicts future severity
- Gender: Males statistically reoffend at higher rates
- Ethnicity: Normed within NZ population groups
A "moderate risk" RoC*RoI classification typically indicates approximately 50-70% probability of reconviction within 5 years � a critical data point for Parole Board decision-making. However, RoC*RoI's limitation is its inability to capture change: an offender who completes intensive treatment receives the same risk score as before intervention.
RoC*RoI should be interpreted alongside dynamic risk instruments (VRS, LS/CMI) that capture treatment progress and behavioral change. This dual assessment approach represents best practice in forensic psychology.
Dynamic Risk Measurement: Violence Risk Scale (VRS)
The Violence Risk Scale (VRS) represents a significant advancement over purely actuarial instruments by integrating dynamic (changeable) risk factors with stage-of-change methodology. Developed by Wong and Gordon, the VRS is particularly valuable for offenders with histories of violent offending.
VRS at a Glance
- Type: Structured Professional Judgment (SPJ)
- Purpose: Assesses violence risk and treatment amenability
- Format: 26 items (6 static, 20 dynamic)
- Unique Feature: Stage-of-change scoring for dynamic factors
- Output: Violence risk rating with treatment targets
The VRS employs a unique stage-of-change scoring system adapted from the Transtheoretical Model of behavioral change:
Pre-contemplation
No recognition of problem; no intention to change behavior.
Contemplation
Recognition of problem; ambivalent about change.
Preparation
Intending to take action; beginning to plan change.
Action
Actively modifying behavior; implementing change strategies.
Maintenance
Sustaining gains; preventing relapse long-term.
VRS Dynamic Factors
- Violence severity and frequency
- Age at first violent offense
- Weapon use patterns
- Antisocial personality features
- Criminal attitudes and cognitive distortions
- Substance abuse (linked to violence)
- Emotional regulation deficits
Case Management Integration: LS/CMI
The Level of Service/Case Management Inventory (LS/CMI) is widely considered the gold standard for general offending risk assessment. Its unique strength lies in its integration of risk prediction with structured case management planning.
LS/CMI at a Glance
- Type: Risk-Need Assessment with Case Management
- Purpose: Predicts general offending risk; identifies treatment targets
- Format: 43 items across 8 need domains + case management section
- Output: Risk/Need profile with prioritized intervention recommendations
- Administration: Interview + collateral records
The LS/CMI assesses eight criminogenic need domains aligned with the RNR (Risk-Need-Responsivity) principle:
Criminal History
Prior convictions, institutional misconduct patterns.
Education/Employment
Academic deficits, job instability, skill gaps.
Family/Marital
Relationship dysfunction, family conflict, poor parenting.
Leisure/Recreation
Absence of prosocial activities, boredom.
Companions
Criminal associates, antisocial peer influence.
Alcohol/Drug Problem
Substance abuse patterns, dependence severity.
Procriminal Attitude
Criminal thinking, rationalization, cognitive distortions.
Antisocial Pattern
Aggression, rule-breaking, impulsivity.
Protective Factor Analysis: SAPROF Methodology
The Structured Assessment of Protective Factors (SAPROF) complements risk-focused instruments by systematically evaluating factors that reduce reoffending risk. While instruments like VRS and LS/CMI focus primarily on risk factors, SAPROF provides a strengths-based perspective that balances the overall risk formulation.
SAPROF at a Glance
- Type: Protective Factors Assessment (SPJ)
- Purpose: Identifies strengths that mitigate violence risk
- Format: 17 protective factors across 3 categories
- Output: Protective factors profile integrated with risk assessment
- Unique Value: Strengths-based perspective often missing from risk assessments
SAPROF Protective Factors
- Motivational factors: Treatment motivation, life goals, future orientation
- External factors: Social support, intimate relationship, employment, housing
- Personal factors: Empathy, coping, self-control, substance use management
An offender with strong SAPROF scores (e.g., motivated for treatment, stable whanau support, clear employment goals) presents a different risk picture than an offender with identical VRS/LS/CMI scores but minimal protective factors. This balanced perspective enables more nuanced clinical formulation.
Case Study Application
📌 Medium-Risk Classification with Contemplative/Preparation Stage Indicators
Consider a 32-year-old male serving a sentence for aggravated robbery, with a history of methamphetamine dependence and violent offending. His assessment profile:
- RoC*RoI: Moderate risk (65th percentile for general reconviction)
- VRS: Medium-high violence risk; contemplative stage for substance abuse; preparation stage for criminal attitudes
- LS/CMI: Medium need; highest scores in Alcohol/Drug, Companions, Antisocial Pattern
- SAPROF: Moderate protective factors; strong motivation for treatment; emerging whanau support
This integrated profile suggests that while static risk remains elevated (RoC*RoI), the offender is actively engaging in treatment (contemplative/preparation stages) and possesses protective factors that may facilitate successful reintegration. Treatment recommendations would prioritize DTP completion, relapse prevention planning, and strengthening whanau connections.
Integrating Multiple Instruments: Best Practice
Modern forensic psychology practice recommends multi-instrument assessment rather than reliance on any single tool. Each instrument captures different dimensions of risk:
RoC*RoI
Actuarial baseline risk (static, unchangeable) providing foundation for risk prediction.
VRS
Violence-specific risk with treatment amenability staging for targeted interventions.
LS/CMI
General offending risk with integrated case management for comprehensive planning.
SAPROF
Protective factors that moderate risk and support rehabilitation success.
Together, these instruments provide a comprehensive risk profile that satisfies the requirements of Section 21 parole risk assessments while enabling clinically informed treatment planning.
