Genogram & Ecomap in
Community Health Nursing
Community health nurses use genograms and ecomaps together as core family assessment tools. Learn how each works, when to use them, and how to document findings for NLN-aligned nursing practice.
Two Tools, One Complete Assessment
The genogram and ecomap were designed to work together. Neither tells the full story alone — together, they give nurses a complete picture of the family's health context.
Genogram reveals
- Hereditary health risks (heart disease, diabetes, cancer)
- Mental health history across generations
- Substance use patterns in the family
- Family structure (single parent, blended family, etc.)
- Recent losses, deaths, life transitions
- Intergenerational trauma indicators
Ecomap reveals
- Healthcare access (providers, insurance, transportation)
- Social support network strength
- Community resource connections
- Employment and financial stability indicators
- Educational support for children
- Stressors draining family energy
How to Create a Nursing Genogram
Standard McGoldrick-Gerson-Petry notation (4th ed., 2020) — used in NLN-accredited nursing programs
Identify the Index Person
Mark the client or family with a double border (double square or double circle). Include full name, date of birth, and any significant health conditions.
Map Three Generations
Document grandparents (top row), parents and their siblings (middle row), and the client with siblings and children (bottom row). Oldest generation at top, left to right by birth order.
Document Vital Status
Mark deceased family members with an X through the shape. Note age at death and primary cause of death. Include year of death when known.
Record Relationship Structures
Connect partners with horizontal lines (solid = married, double slash = divorced, single slash = separated). Vertical lines connect parents to children.
Add Medical History
Note hereditary conditions (heart disease, diabetes, cancer, mental illness, substance use) in or beside each person's symbol. This reveals health risk patterns across generations.
Indicate Emotional Patterns
Add relationship overlays for significant bonds: close relationships (thick solid line), conflict (zigzag), cutoff (two parallel lines with gap). Focus on patterns most relevant to the nursing assessment.
Clinical Standard
Nursing genograms follow the McGoldrick-Gerson-Petry standard (4th edition, 2020), the same notation used in family medicine, social work, and marriage and family therapy. This ensures your genograms are legible to the entire care team.
How to Create a Nursing Ecomap
Ann Hartman's ecomap notation (1975) — standard in social work and community health nursing
Draw the Family Circle
Place a large circle in the center representing the family unit (or nuclear family). Write family members' names or use the genogram inside the circle.
Identify External Systems
Draw smaller circles around the family for each system: healthcare providers, school, work/employer, church/spiritual community, extended family, social services, informal supports (neighbors, friends), recreational/community groups.
Draw Connection Lines
Connect the family circle to each external system. Use thick solid lines for strong connections, thin lines for weak ones, dashed lines for fragile/inconsistent ones, and hatched/jagged lines for stressful relationships.
Add Directional Arrows
Add arrows to show resource flow direction. Arrow pointing toward family = system provides support. Arrow pointing away = family gives to system. Arrows in both directions = reciprocal relationship.
Note Absent Systems
Draw empty circles or note gaps for systems the family needs but lacks. Common gaps in community health: no primary care provider, no dental care, no childcare, no transportation, no mental health services.
Analyze and Document
Identify stressors (jagged lines, one-directional drain), strengths (thick lines, reciprocal arrows), and gaps (missing systems). Document findings in the nursing assessment and use in care planning.

The Johnson Family
Maria Johnson, 34, referred by WIC for home visiting. Two children ages 2 and 4. Partner works night shift. New to the community.
Genogram Findings
- Maternal grandmother: Type 2 diabetes, age 58
- Maternal grandfather: MI at 52, deceased age 61
- Mother (Maria): gestational diabetes in both pregnancies
- Father: alcohol use disorder history (paternal grandfather also)
- Strong, close relationship between Maria and her mother (lives 2 states away)
Ecomap Findings
- No primary care provider established
- WIC — strong, supportive connection
- No local extended family connections
- Partner employed but limited schedule for childcare
- No childcare arrangement — stressor line
- Neighbor (Ms. Chen) — identified as informal support

NLN & ANA Competency Alignment
Genogram and ecomap construction fulfills multiple NLN community health nursing competency domains
Note for students: Check your specific program's requirements. Some programs use different notation standards or require specific software. GenogramAI follows the McGoldrick-Gerson-Petry 4th edition standard, which is the most widely used in accredited nursing programs.
Frequently Asked Questions
How are genograms used in community health nursing?
Community health nurses use genograms to document a family's health history across at least three generations — recording hereditary conditions, family structure, deaths, and emotional relationship patterns. This identifies genetic risk factors and intergenerational health behaviors that inform preventive care priorities.
What is the difference between a genogram and ecomap in nursing?
A genogram looks inward and backward — mapping family structure, medical history, and relationship patterns across generations. An ecomap looks outward — showing the family's current connections to community systems. The genogram reveals 'what health risks does this family carry?' The ecomap reveals 'what resources and stressors surround them now?'
