Forensic Genogram
Map Violence & Trauma Patterns
Track intergenerational patterns of violence, abuse, incarceration, and trauma. The essential tool for forensic psychologists, criminologists, and criminal justice professionals conducting risk assessments.
Violence Doesn't Start in a Vacuum
Understanding intergenerational patterns is essential for risk assessment
The Cycle of Violence Is Intergenerational
Your client was abused as a child. His father was abused. His grandfather was abused. The pattern didn't start with him—but understanding where it started is essential for risk assessment.
Forensic genograms reveal intergenerational trauma patterns that predict violence risk better than individual assessment alone.
Courts Need Visual Evidence
You're presenting a mitigation case. The defense needs to show the jury that your client's violent behavior emerged from a family system saturated with abuse, addiction, and incarceration.
A genogram makes three generations of trauma visible in one image—more powerful than pages of testimony.
Risk Assessment Requires Context
Standard risk assessment tools measure individual factors. But violence is learned behavior. Without family context, you're missing half the picture.
Forensic genograms add systemic context to actuarial risk assessment, improving predictive validity.
Trauma Is Not an Excuse—It's an Explanation
Understanding the family system doesn't justify violence. But it does explain how someone became violent, and more importantly, what interventions might break the cycle.
Forensic genograms inform treatment planning, not just assessment. They show where to intervene.
What to Map in a Forensic Genogram
Track risk factors across generations
Violence & Abuse Tracking
Map physical abuse, sexual abuse, domestic violence, and neglect across generations. See where patterns begin.
Incarceration History
Track who has been incarcerated, for what offenses, and for how long. Identify intergenerational criminal justice involvement.
Substance Abuse Patterns
Map alcohol and drug abuse across generations. See how substance use correlates with violence and trauma.
Emotional Relationships
Show enmeshed, cutoff, and conflicted relationships. Identify family triangles that perpetuate dysfunction.

Intergenerational factors that inform risk evaluation
Forensic Applications
Where forensic genograms make the difference
Violence Risk Assessment
Map intergenerational patterns of violence to improve actuarial risk assessment. Context matters for predicting future behavior.
Mitigation in Capital Cases
Present compelling visual evidence of intergenerational trauma, abuse, and neglect for sentencing mitigation.
Child Custody Evaluations
Assess family dynamics, abuse histories, and protective factors when determining custody arrangements.
Treatment Planning
Identify intervention points in the family system. Breaking cycles requires understanding where they started.
Research on Intergenerational Violence
Evidence supporting the forensic genogram approach
Research consistently demonstrates that violence, abuse, and criminal behavior cluster in families across generations. The Adverse Childhood Experiences (ACE) studyestablished clear links between childhood trauma and later violence, substance abuse, and incarceration. Children who witness domestic violence are significantly more likely to become perpetrators or victims as adults.
Criminological research identifies multiple pathways through which violence transmits across generations: social learning (modeling violent behavior),attachment disruption (insecure attachment increases aggression),neurobiological effects (trauma affects brain development), andenvironmental continuity (poverty, neighborhood violence, lack of resources).
The genogram visualizes these overlapping factors. When you can see that a client's father was incarcerated, grandfather was an alcoholic who was violent, and great-grandfather died young in unclear circumstances—the pattern becomes undeniable. This visual evidence is particularly powerful in courtroom settings where juries need to understand complex family dynamics quickly.
Key Research Findings
- ACE Study: Each additional adverse childhood experience increases risk of violence, substance abuse, and incarceration
- Intergenerational Transmission: Children of incarcerated parents are 3-6x more likely to be incarcerated themselves
- Domestic Violence Cycle: Boys who witness DV are 2-3x more likely to become abusers; girls are more likely to be victimized
- Trauma and Brain Development: Chronic childhood stress affects prefrontal cortex development, impairing impulse control

Create a Forensic Genogram
Map the family structure
Start with your subject and build out 2-3 generations. Include all family members, even those with limited contact.
Add trauma and abuse history
Mark physical abuse, sexual abuse, neglect, and domestic violence for each generation. Note perpetrators and victims.
Track criminal justice involvement
Add incarceration history, arrests, types of offenses. Note patterns across generations.
Map substance abuse
Indicate alcohol and drug abuse. Note correlations with violence and trauma.
Identify intervention points
Analyze patterns to inform risk assessment and treatment planning. Where can the cycle be broken?
Forensic Genogram FAQs
What is a forensic genogram?
A forensic genogram is a specialized genogram used in criminal justice and forensic psychology to map intergenerational patterns of violence, abuse, trauma, substance use, and incarceration. It provides systemic context for understanding criminal behavior and assessing future risk.
How is it used in court?
Forensic genograms are commonly used in mitigation cases, particularly capital defense, to visually demonstrate intergenerational trauma that contributed to the defendant's behavior. They're also used in custody evaluations, violence risk assessments, and competency evaluations.
Can it predict violence?
A genogram alone doesn't predict violence, but it adds important context to actuarial risk assessment tools. Research shows that intergenerational patterns of violence, abuse, and substance use are significant risk factors. The genogram makes these patterns visible and trackable.
Is it appropriate for treatment planning?
Yes. Beyond assessment, forensic genograms inform treatment by identifying where cycles began and which relationships might support change. They're used in trauma-focused therapy, family therapy with offenders, and reentry planning.
What training is required?
Forensic genogram interpretation requires training in both family systems theory and forensic assessment. Graduate programs in forensic psychology, forensic social work, and criminology typically include genogram training. Professional continuing education courses are also available.
How do I document sensitive information ethically?
Document only information relevant to the assessment purpose. Use clinical language, not judgmental terms. Note the source of information (self-report, records, collateral). Be aware that forensic genograms may become part of legal records and could be viewed by multiple parties.
What if family members disagree about history?
Document discrepancies. Different family narratives about abuse, violence, or trauma are themselves clinically significant. Note whose account is being used and any contradictory information. The pattern of disagreement often reveals family dynamics.
How do I handle unknown information?
Mark unknown information clearly. Gaps in family history—especially around violence, incarceration, or trauma—are common in forensic populations due to family fragmentation, cutoffs, and secrecy. The gaps themselves can be meaningful patterns.
Map Intergenerational Patterns
Understand where violence begins to know how to stop it.
