Static vs Dynamic Risk Factors

Mon, 01 Jun 2026 00:00:00 +0000

Module 2 · Risk Application

Prediction and intervention are not the same thing.

Not all risk factors are created equal. Some factors are static. Others are dynamic. The distinction matters because prediction and intervention are not the same thing.

Key takeaway

The strongest predictors may not be treatment targets.

Static Risk Factors

Static factors typically do not change over time, or only change in one direction by increasing risk exposure.

Examples include:

criminal history
age at first arrest
gender
early life adversity

These factors are often strong predictors of recidivism. But they are not direct intervention targets.

The idea: Some factors predict risk but are not easily changeable.

Illustration

Static and dynamic factors serve different purposes

Static factors are often strong predictors, but dynamic factors are the main targets for intervention.

Prediction and intervention are related, but they are not the same task.

Dynamic Risk Factors

Dynamic factors can change over time.

Examples include:

substance use
employment and education
peer associations
criminal thinking patterns
family relationships

These factors help explain changes in risk and provide targets for intervention.

Why This Matters

Strong prediction does not automatically identify treatment needs
Dynamic factors are the focus of programming and supervision targets
Effective practice requires understanding both static and dynamic factors

Risk Assessment and Needs Assessment

Most risk assessments include both static and dynamic factors.

Needs assessments focus exclusively on dynamic criminogenic needs because they are changeable intervention targets.

Bottom Line

The strongest predictors may not be treatment targets. Effective correctional practice requires understanding both static and dynamic risk factors.

Criminal History Predicts Risk—But Is It a Need?

Module 3 · Risk Application

Strong predictor does not mean good intervention target.

One of the strongest predictors of future offending is criminal history. That finding has been replicated for decades. But there is an important distinction: strong predictor does not mean good intervention target.

Key takeaway

Criminal history helps estimate risk, but not what to change.

Why Criminal History Predicts Risk

Criminal history is useful because it captures accumulated risk exposure over time. People with more extensive criminal histories reoffend at higher rates.

That makes criminal history very useful for prediction.

The idea: Criminal history predicts risk, but it is commonly measured as a static factor.

Illustration

Predictors are not always needs

Criminal history is a strong predictor of future offending, but it is not something practitioners can directly change through intervention.

Some factors help predict recidivism. Fewer factors also guide intervention.

Why It Is Not a Direct Intervention Target

Criminal history is commonly measured as a static factor. We cannot:

change prior arrests
change prior convictions
change age at first arrest

That makes criminal history much less useful for intervention.

What Can Be Targeted

By contrast, factors such as substance use, peer associations, and criminal thinking patterns may be somewhat less predictive than criminal history alone, but they can change and become targets for intervention.

What Belongs in an Assessment?

Notice the lower-left corner of the figure. Many characteristics can be measured. Very few help predict recidivism or guide intervention.

This is an important lesson in assessment development: just because something can be measured does not mean it belongs in an assessment.

Why This Matters

Prediction and intervention serve different purposes
Strong predictors are not automatically treatment targets
Effective correctional practice requires both risk and needs assessment

Bottom Line

Criminal history helps estimate risk, but not what to change. Strong predictors are not automatically good treatment targets.

Criminal Thinking Patterns

Fri, 05 Jun 2026 00:00:00 +0000

Module 3 · Risk Application

Criminal thinking is changeable.

One of the most important criminogenic needs is criminal thinking. But this concept is often misunderstood. Criminal thinking does not refer to intelligence, and it does not mean someone is inherently “criminal.”

Key takeaway

Unlike criminal history, criminal thinking patterns tell us something we can potentially change.

What Criminal Thinking Means

Criminal thinking refers to patterns of thinking that support, justify, or facilitate offending.

Examples include:

minimizing harm
blaming others
entitlement
rationalizing behavior
impulsive decision-making

The idea: Criminal thinking is not about intelligence; it is about thinking patterns that can support offending.

Illustration

Criminal thinking patterns can change

Criminal thinking refers to patterns that support, justify, or facilitate offending. Unlike criminal history, these patterns can become targets for intervention.

These patterns matter because they are linked to recidivism and can be addressed through intervention.

Why These Patterns Matter

These thinking patterns matter because they are associated with higher rates of recidivism.

Unlike criminal history, however, they can change.

That makes them both:

predictors of future offending
intervention targets

Why This Matters for Treatment

This is one reason cognitive-behavioral interventions play such a central role in modern correctional practice.

Some risk factors can be changed
Criminal thinking patterns are among the most important intervention targets
Effective treatment often focuses on changing how people interpret situations, decisions, and consequences

Bottom Line

Unlike criminal history, criminal thinking patterns tell us something we can potentially change. They can help predict future offending and guide intervention.

← Back to Modules Next Module Peers →

Antisocial Peers

Mon, 15 Jun 2026 00:00:00 +0000

Module 4 · Risk Application

Behavior is influenced by the people around us.

One of the strongest criminogenic needs is antisocial peers. In fact, many probation and parole conditions prohibit associating with known justice-involved individuals.

Key takeaway

Who we spend time with helps shape what behaviors become normal.

Why Peers Matter

Peers can affect:

attitudes
decision-making
opportunities
reinforcement of behavior

The idea: Social environments influence behavior.

Illustration

Peer networks shape behavior

Antisocial peers can normalize, encourage, and reward criminal behavior. Prosocial peers can provide support, accountability, and alternative opportunities.

Unlike criminal history, peer associations are dynamic and can become targets for intervention.

How Antisocial Peers Shape Behavior

When people spend time with antisocial peers, criminal behavior can become:

normalized
encouraged
rewarded

How Prosocial Peers Help

At the same time, prosocial peers can provide:

support
accountability
alternative opportunities
positive role models

This is one reason peer associations are included in many needs assessments.

Why This Is Dynamic

Unlike criminal history, peer networks are dynamic. Changing who someone spends time with can alter the opportunities, reinforcement, and social norms that shape behavior.

Why This Matters

Social environments influence behavior
Peer associations can change over time
Effective interventions often focus on building prosocial networks

Bottom Line

Who we spend time with helps shape what behaviors become normal. Peer associations matter because they can reinforce risk or support change.

← Back to Modules Next Module Substance Use →

Substance Use

Fri, 05 Jun 2026 00:00:00 +0000

Module 5 · Risk Application

Some needs are more actionable than others.

Not all criminogenic needs are equally responsive to intervention. Substance use is one of the few domains where we have strong evidence that treatment can reduce need levels—and sometimes reduce risk as well.

Key takeaway

Substance use matters because it predicts risk and is one of the few domains where meaningful change is possible.

Why Substance Use Appears in Needs Assessments

The figure below shows three reasons substance use appears in nearly every major needs assessment.

The idea: Substance use is important because it can create instability, shape behavior, and respond to treatment.

Illustration

Substance use is an actionable need

Substance use appears in major needs assessments because it can create instability, influence behavior, and respond to treatment.

Unlike criminal history, substance use can change, making it an important intervention target.

Substance Use Can Create Instability

First, substance use often creates instability.

It can contribute to:

employment problems
housing instability
supervision violations
association with antisocial peers

Different Substances Can Influence Behavior Differently

Second, different substances can influence behavior in different ways.

For example:

alcohol is often associated with violence and aggression
stimulants can increase impulsive and erratic behavior
opioids are frequently associated with acquisitive crime and economic motivation

The relationship between substance use and crime is not always the same.

Substance Use Is Treatable

Third, substance use is one of the most treatable criminogenic needs.

Unlike criminal history, substance use can change. Successful treatment and recovery can reduce need levels, improve stability, and contribute to reductions in risk.

Why This Matters

Substance use affects far more than drug offending
Different substances can influence different offending patterns
Effective treatment can change one of the most important criminogenic needs

Bottom Line

Substance use is important not only because it predicts risk, but because it is one of the few domains where meaningful change is possible.

School, Work, and Stability

Fri, 26 Jun 2026 00:00:00 +0000

Module 6 · Theory & Dynamics

School and work create stability.

Many people talk about education and employment as if they are the same thing. Risk and needs assessments often treat them differently.

Key takeaway

School and work matter because they create stability, strengthen bonds to conventional institutions, and increase what people have to lose if they return to crime.

School and Work Across the Life Course

The figure below shows why education and employment are treated differently in many risk and needs assessments.

For youth, school is often the primary conventional institution. Assessment items frequently focus on:

school attendance
academic performance
disciplinary problems
attachment to school
educational goals

The idea: School and employment are measured differently, but often serve similar functions.

Illustration

School and work create stability

School and employment are measured differently across the life course, but both can provide structure, accountability, future orientation, and ties to prosocial institutions.

When problems in school or employment accumulate, instability often increases—and as instability increases, so does risk.

Employment Becomes the Primary Institution

For adults, employment often becomes the primary conventional institution. Assessment items frequently focus on:

employment history
job stability
employability
income
work-related attitudes

Why These Domains Matter

Even though these domains are measured differently, they often serve similar functions.

Both can provide:

structure and routine
accountability
future orientation
connections to prosocial institutions

When problems in school or employment accumulate, instability often increases. As instability increases, so does risk.

Why This Matters

This is one reason difficulties in school and employment are considered criminogenic needs. Unlike criminal history, they can change. And because they can change, they become potential targets for intervention.

Education and employment are related but not identical
Assessments measure them differently across the life course
Improvements in school or work can contribute to reductions in need levels and risk

Bottom Line

School and work matter because they create stability, strengthen bonds to conventional institutions, and increase what people have to lose if they return to crime.

← Back to Modules Next Module Social Support →

Social Support

Fri, 05 Jun 2026 00:00:00 +0000

Module 7 · Theory & Dynamics

Support is not always protective.

One of the most important criminogenic needs is social support. But support is not always protective. When people hear “social support,” they often think of something positive. Yet relationships can influence behavior in very different ways.

Key takeaway

The people closest to us help shape what becomes normal, acceptable, and expected.

Supportive Relationships Can Reduce Risk

Supportive relationships can provide:

accountability
encouragement
emotional support
stability
access to prosocial opportunities

The idea: The question is not simply whether someone has support. The question is what kind of support they are receiving.

Illustration

Support can stabilize or reinforce risk

Social relationships can provide accountability, encouragement, and stability—but they can also normalize offending and reinforce antisocial behavior.

The important question is not simply whether someone has support, but what kind of support they are receiving.

Relationships Can Also Reinforce Risk

Social relationships can also reinforce risk.

Examples include:

criminal associates
antisocial peers
enabling intimate partners
substance-using social networks

These relationships can normalize offending, provide criminal opportunities, and reinforce antisocial behavior.

What Kind of Support?

Historically, many assessments treated family relationships and peer relationships as separate domains.

More recent perspectives increasingly recognize that both may reflect a broader concept: social support and social bonds.

The important question is often not who the relationship is with, but whether the relationship promotes stability and prosocial behavior or reinforces risk.

Why This Matters

Social relationships can increase or decrease risk
The quality of support matters more than the mere presence of support
Building prosocial support networks is often a major intervention goal

Bottom Line

The people closest to us help shape what becomes normal, acceptable, and expected. Social support matters because it can either promote stability or reinforce risk.

Stabilizers and Destabilizers

Fri, 05 Jun 2026 00:00:00 +0000

Module 8 · Theory & Dynamics

Stability may matter more than any single domain.

Historically, many risk and needs assessments included leisure and recreation as a separate criminogenic need. But more recent research suggests that leisure itself may not be the most important part of the story.

Key takeaway

Stability often supports long-term success, while instability can undermine progress across many areas of life.

From Leisure to Stability

Historically, many risk and needs assessments included leisure and recreation as a separate criminogenic need.

The idea was straightforward: people who lack structured, prosocial activities may be more likely to engage in antisocial behavior.

But more recent research suggests that leisure itself may not be the most important part of the story. Instead, a growing body of work points toward a broader concept: stability versus instability.

The idea: Many traditional needs domains may reflect a broader network of stabilizing and destabilizing influences.

Illustration

Stabilizers and destabilizers shape risk

Stability can be supported by relationships, housing, transportation, treatment access, and other resources. Instability can be driven by barriers, stress, and disruption.

Many influences affect risk through a common pathway: whether they support or disrupt stability.

What Creates Stability?

Stabilizers can include:

supportive relationships
reliable transportation
stable housing
access to treatment and services
childcare and parenting support

These factors create structure, predictability, and opportunities for success.

What Creates Instability?

Destabilizers can include:

housing instability
transportation barriers
food insecurity
unmet service needs
parenting stress

These factors create stress, uncertainty, and disruption.

The Common Pathway

Many of these influences affect risk through a common pathway: stability.

The issue is often not whether someone has hobbies. The issue is whether they have the resources, structure, and support necessary to maintain a stable life.

Why This Matters

Some traditional needs domains may reflect broader stabilizing or destabilizing influences
Stability often supports long-term success and desistance
Instability can undermine progress across multiple areas of life

Bottom Line

Historically, leisure was often treated as a separate need. More recent perspectives increasingly view it as one part of a broader network of stabilizers and destabilizers.
