Genogram Example: Symbols, Types, and Clinical Uses

Key Takeaways

A genogram example maps family structure, medical history, and relationships across at least three generations using standardised symbols.

Squares represent males, circles represent females, and horizontal lines denote relationships – standards established by McGoldrick and Gerson in 1985.

Therapists, GPs, social workers, and mental health practitioners all use genograms to identify intergenerational patterns and hereditary risk factors.

A three-generation genogram example typically includes the patient, their parents, and grandparents, with relationship quality and health data annotated.

Digital patient records and clinical documentation tools help practitioners store and update genogram data securely in line with GDPR and HIPAA requirements.

Genogram Example: Understanding the Basics

A genogram example does something a standard family tree cannot: it maps not just who is related to whom, but how those relationships function, what conditions run through a family line, and where patterns of behaviour, illness, or emotional conflict tend to repeat. Developed by psychiatrist Murray Bowen and later standardised by Monica McGoldrick and Randy Gerson in their foundational 1985 text Genograms in Family Assessment, genograms have become a core assessment tool across therapy, primary care, and social work.

The basic genogram example uses a set of agreed symbols – squares for males, circles for females, horizontal lines for relationships – arranged across at least three generations. What distinguishes it from a genealogical chart is the clinical layer: annotations for hereditary conditions, markers for emotional cutoff or enmeshment, and relational lines that distinguish a close bond from a hostile or estranged one. Clinicians working in mental health settings rely on genograms precisely because the visual format reveals what a patient intake form cannot.

This guide covers genogram symbols, structure types, real clinical applications, and what practitioners need to consider when storing genogram data within a digital records system.

Core Genogram Symbols and What They Mean

Symbol consistency is what makes a genogram example readable across disciplines. When a social worker transfers a case to a community mental health team, both practitioners need to interpret the same diagram without ambiguity. The McGoldrick-Gerson notation system – widely adopted by the American Association for Marriage and Family Therapy (AAMFT) – provides that shared language.

Genogram Example: Gender and Individual Symbols

The foundational symbols in any genogram example are simple geometric shapes. A square represents a male family member. A circle represents a female family member. A triangle is used for a pregnancy or foetus. When a family member is deceased, an X is placed inside the shape. A person identified as the presenting patient or index person – the individual who is the focus of the assessment – is typically indicated by a double border around their square or circle.

Age is placed inside the shape. Birth and death years can be noted outside. A diagonal line through a shape marks a deceased individual, while a double-bordered shape identifies the client. These conventions apply regardless of whether you are constructing a genogram example for therapy, a medical genogram for a GP consultation, or a genogram for social work assessment.

Genogram Relationship Symbols: Lines and Their Meanings

Horizontal lines between two shapes indicate a relationship. A single solid horizontal line represents a committed relationship or marriage. Two lines (double horizontal bar) indicate a marriage. A dashed horizontal line marks a non-married committed relationship or cohabitation. A line with a single slash through it represents separation; a double slash indicates divorce.

Vertical lines drop down from a couple line to connect children, ordered from left (oldest) to right (youngest). Adopted children are shown with a dashed vertical line; foster placements similarly. Twins share a single vertical drop with a horizontal connector at their level – identical twins joined by a horizontal bar, fraternal twins with an angled connector.

Genogram Example: Emotional and Relational Relationship Lines

The relational layer is what separates a clinical genogram example from a simple family diagram. Emotional relationship lines are drawn between any two individuals – not just couples – to show how they relate to one another. A straight thick line indicates a close relationship. A double line (or two parallel lines) marks an enmeshed relationship, where boundaries between individuals are poorly defined. A jagged or zigzag line signals a hostile or conflictual relationship. A broken line indicates emotional cutoff – a family member who has severed contact.

These relational markers draw directly from Family Systems Theory, the framework developed by Murray Bowen. Concepts like triangulation – where a third party is drawn into a conflict between two others – can be mapped directly onto the genogram, helping a therapist identify intergenerational patterns that a patient may not consciously recognise in themselves.

Genogram Example by Type: From Nuclear to Extended Families

Not every clinical situation calls for the same genogram format. The appropriate genogram example depends on the assessment goal, the available information, and the clinical setting. A GP conducting a brief family health history check needs a different structure than a family therapist working with a couple through intergenerational trauma.

Simple Genogram Example: Nuclear Family

A nuclear family genogram example covers the immediate household: two parents (or a single parent), their children, and the marital or partnership relationship between the adults. This is the entry-level format used in GP clinics and paediatric settings when the aim is to capture a quick picture of the home environment, sibling structure, or parental health status.

Even this basic genogram example becomes clinically useful when medical annotations are added. A parent with a documented history of Type 2 diabetes, hypertension, or a mood disorder – noted inside or beside their symbol – gives the practitioner immediate context for a child’s presenting symptoms or risk profile.

Extended Family Genogram Example

An extended family genogram example broadens the view to include grandparents, aunts, uncles, and cousins. This format is standard practice in family therapy and social work, where the National Association of Social Workers (NASW) recognises genograms as a core assessment tool. The extended format surfaces hereditary risk patterns – a cluster of cardiovascular disease on the paternal side, or a multigenerational pattern of addiction – that a two-generation view would miss entirely.

Social workers constructing a genogram example for a safeguarding assessment may also use the extended format to map kinship networks – identifying which relatives could provide support, which relationships carry risk, and where isolation exists within the family system.

Medical Genogram Example

A medical genogram example focuses specifically on hereditary conditions and health history across generations. Rather than mapping emotional relationships in depth, this format prioritises disease annotations: heart disease, cancers, diabetes, autoimmune conditions, and mental health diagnoses are noted beside each individual’s symbol.

The Royal College of General Practitioners (RCGP) supports the use of family health history tools in primary care to identify patients at elevated risk for conditions like breast cancer, familial hypercholesterolaemia, or hereditary bowel disease. A medical genogram example provides the visual structure for that risk mapping – though clinicians should frame hereditary notations as indicators of risk, not diagnoses, and communicate them carefully to patients.

Three-Generation Genogram Example in Clinical Practice

The three-generation genogram example is the clinical standard. McGoldrick and Gerson’s notation guidelines specify at least three generations as the minimum for meaningful pattern identification – and most clinical settings follow that guidance. The three layers are: the patient (generation one), their parents (generation two), and their grandparents (generation three).

In practice, constructing a three-generation genogram example during an initial therapy assessment session typically takes between 20 and 40 minutes. The clinician begins with the patient’s generation, then works upward. As the genogram takes shape, patterns that the patient had not consciously connected often become visible – a grandmother with severe anxiety, a parent who replicated that emotional cutoff with their own children, a recurring pattern of early bereavement across three generations.

Three-Generation Genogram Example: Annotating Medical History

When the three-generation genogram example includes medical history, the annotation system becomes critical. Each individual’s hereditary conditions are written beside their symbol using agreed abbreviations: HBP for high blood pressure, DM2 for Type 2 diabetes, CA for cancer (with site specified), MDD for major depressive disorder. Conditions that appear in multiple family members across generations are immediately visible in a way that a text-based medical history cannot replicate.

The World Health Organization (WHO) has consistently supported family health history as a core component of preventive healthcare. A well-constructed three-generation genogram example functions as a living document – updated at each significant life event or new diagnosis, rather than completed once and filed. Practitioners using digital patient record systems can attach genogram files directly to a patient’s record, making updates straightforward and ensuring the information is accessible across care team members.

Three-Generation Genogram Example: Adverse Childhood Experiences

Mental health practitioners increasingly use the three-generation genogram example to map Adverse Childhood Experiences (ACEs) – a framework supported by extensive research linking early-life stressors to long-term health outcomes. On a genogram, ACEs can be noted beside relevant family members: parental substance misuse, domestic violence, parental mental illness, or early parental separation.

When these markers appear across multiple generations, the genogram makes the intergenerational transmission of trauma visible in a way that is clinically useful and often therapeutically powerful for the patient. Practitioners working in psychology settings and trauma-informed care programmes cite genograms as one of the most effective tools for externalising family system dynamics that might otherwise remain implicit throughout therapy.

Genogram Example in Healthcare: Therapy, Social Work, and Primary Care

The genogram example looks different depending on who is using it and why. The underlying symbol system is consistent, but the focus, depth, and update cadence vary considerably across clinical disciplines. Understanding where genograms are used – and how – helps practitioners decide which format is appropriate for their setting.

Genogram Example for Therapy and Counselling

Family therapists and counsellors use genograms most intensively. The British Association for Counselling and Psychotherapy (BACP) recognises systemic and family-based approaches – which lean heavily on genogram work – as evidence-based practices for a wide range of presenting issues. A genogram example in this context typically spans three or more generations and is built collaboratively with the client over one or more sessions.

The goal is not just documentation but insight. When a client sees their emotional patterns mapped visually across three generations, the depersonalisation of the problem – “this is a pattern in my family system, not a personal failing” – can be therapeutically significant. Therapists working in psychiatric settings and private practice alike use genograms as a foundation for systemic treatment planning.

Genogram Example for Social Work Assessment

Social workers use the genogram example differently. Here, the tool is primarily an assessment instrument for mapping support networks, identifying risk, and documenting family complexity during statutory assessments. The NASW includes genogram construction in foundational social work training for this reason.

A genogram example for a child protection assessment might include the child at the centre, both biological parents (even if not cohabiting), each parent’s relationship history, and any kinship carers. Relational lines marking hostility, conflict, or cutoff between adults are particularly important in this context. The genogram helps the social worker map not just who is present in a child’s life, but the quality and safety of those relationships.

Medical Genogram Example in Primary Care

In primary care, the genogram example is most often a medical genogram focused on hereditary risk. A GP completing a new patient registration might ask about family health history and sketch a basic two- or three-generation diagram. The RCGP recommends structured family history collection as part of comprehensive patient assessment, particularly for conditions with known hereditary components.

Primary care teams increasingly use digital intake forms to collect family health history before the first appointment, then build or update the genogram during the consultation. This approach reduces session time spent on data collection and ensures the information is captured in a structured format within the patient record – making it available to other members of the care team without requiring a verbal handover.

Genogram Example vs Family Tree: Key Differences

The question comes up regularly: how does a genogram example differ from a family tree? The distinction matters clinically, because conflating the two leads to underutilising the genogram’s analytical power.

A family tree is genealogical. Its purpose is to document lineage – who descended from whom, and when. It records names, dates, and biological relationships. A genogram example does all of that, but adds three dimensions that a family tree does not: functional relationships (the quality of connection between individuals), health and medical data (hereditary conditions and mental health history), and behavioural patterns (substance use, trauma history, recurring relational dynamics). The family tree is a historical record. The genogram is a clinical assessment tool.

A second distinction is orientation. Family trees typically show the past – ancestors. Genograms are constructed with the current patient at the centre and used to inform present clinical decisions. The Journal of Marital and Family Therapy has published extensively on genogram methodology, consistently framing it as a prospective tool: its value is in what it reveals about a patient’s current functioning and future risk, not in preserving family history for its own sake.

Practitioners working in functional medicine and integrative settings, where family history informs lifestyle and treatment recommendations, tend to use a hybrid format – capturing the genealogical structure of a family tree with the clinical annotations of a genogram. This approach works well when the clinical goal is preventive rather than therapeutic.

Storing Genogram Data: Compliance and Digital Records

A completed genogram example contains sensitive personal and medical data about multiple individuals – not just the patient, but their parents, grandparents, and siblings. That data carries significant regulatory weight.

Under the General Data Protection Regulation (GDPR), health data is classified as a special category of personal data requiring explicit consent and appropriate technical safeguards. The UK’s Information Commissioner’s Office (ICO) provides specific guidance for health and social care organisations on how this data must be stored, accessed, and retained. In the United States, HIPAA applies equivalent protections to patient health information, including family medical history documented in clinical records. The Care Quality Commission (CQC) in the UK also expects registered providers to demonstrate appropriate information governance around clinical documentation – including assessments containing family history data.

Practically, this means a genogram example stored as a paper document in an unlocked filing cabinet is a compliance risk. Clinicians who photograph a hand-drawn genogram and store it in an unencrypted folder face similar exposure. Practices using a structured patient record system with role-based access controls and audit trails are in a considerably stronger position – both for regulatory compliance and for clinical continuity.

When multiple practitioners within a clinic need to access the same patient’s genogram – for example, in a multi-disciplinary team – a centralised patient management system ensures each team member sees the most current version without reliance on verbal handover or physical file sharing. That consistency reduces clinical risk and supports the kind of collaborative care that complex cases often require.

Conclusion

A well-constructed genogram example gives clinicians a view of a patient that no intake form or verbal history can replicate. Three generations of family structure, health data, and relational quality – mapped in a single diagram – surface patterns that inform diagnosis, treatment planning, and risk assessment across therapy, social work, and primary care.

The symbol system is learnable in an afternoon. The clinical depth the genogram unlocks takes longer to master, but the return is significant: patients who see their family patterns mapped often engage more deeply with their treatment. Clinicians who update genograms across a patient’s care journey build a richer longitudinal picture than episodic notes alone can provide.

For practices moving toward structured clinical documentation, integrating genogram storage into a digital patient record system is a practical step that improves both compliance and care continuity.
