Structural Family Therapy Genogram
Map family subsystems, boundaries, hierarchies, and coalitions using Minuchin's structural framework. Visualize where the family organization is creating or maintaining dysfunction.
What Is a Structural Family Therapy Genogram?
Salvador Minuchin's Structural Family Therapy (1974) views the family as an organized system with predictable patterns of interaction. The family's structure, meaning its subsystems, boundaries, and hierarchies, determines how members relate to each other. When this structure is dysfunctional, symptoms appear in individual members.
A structural family therapy genogram adapts the standard genogram to emphasize these organizational patterns. While a standard genogram shows who is in the family and how they relate emotionally, a structural genogram maps the invisible architecture: Where are the boundaries? Who holds power? Which subsystems are enmeshed? Where are coalitions forming across generational lines?
Minuchin's Core Concepts
Minuchin identified three key structural elements: subsystems (parental, spousal, sibling), boundaries (rigid, diffuse, or clear), and hierarchies(who holds authority). Dysfunction arises when boundaries are too rigid (disengagement) or too diffuse (enmeshment), when hierarchies are inverted, or when coalitions cross generational lines. The structural genogram maps all of these.
When to Use a Structural Genogram
Clinical situations where mapping family structure reveals the path to intervention
Child Behavior Problems
When a child is the identified patient, structural genograms often reveal hierarchy inversions, parental disengagement, or cross-generational coalitions that maintain the behavior.
Enmeshed Family Systems
Families where members cannot differentiate, where boundaries between parent and child are blurred, and where individual autonomy is suppressed in favor of family fusion.
Disengaged Family Systems
Families where members are emotionally isolated, where a child's distress goes unnoticed, or where the family barely functions as a unit despite living together.
Single-Parent and Blended Families
Map the structural reorganization that occurs after divorce, death, or remarriage. Identify where hierarchy confusion, loyalty conflicts, or role ambiguity create dysfunction.
Parentified Children
When a child has assumed adult responsibilities, the structural genogram shows the hierarchy inversion and helps the therapist plan interventions to restore appropriate roles.
Key Elements to Map
Structural information to capture for each family
Subsystem Boundaries
Map the parental subsystem, sibling subsystem, and extended family subsystem. Show whether boundaries are rigid (impermeable), diffuse (enmeshed), or clear (healthy).
Parental Hierarchy
Who holds executive authority in the family? Is the hierarchy appropriate (parents above children) or inverted? Are grandparents undermining parental authority?
Parentified Children
Identify children who function in a parental role: caring for siblings, managing household tasks, mediating parental conflicts, or emotionally supporting a parent.
Enmeshment Indicators
Diffuse boundaries between members: excessive emotional reactivity, inability to tolerate autonomy, over-involvement in each other's lives, speaking for other members.
Disengagement Markers
Rigid boundaries between members: emotional distance, unawareness of other members' lives, lack of support, a child's problems going unnoticed for extended periods.
Cross-Generational Coalitions
Alliances that cross the generational boundary: a parent-child coalition against the other parent, a grandparent-grandchild coalition that undermines the parent.
Triangulation Patterns
The specific triangles operating in the family: which dyad is in conflict, who gets pulled in as the third, and what role the third plays (mediator, scapegoat, ally).
Power and Decision-Making
Who makes decisions about finances, discipline, household rules, and family activities? Is power shared appropriately or concentrated in one member?
Clinical Example: The Reeves Family
Fictional composite case for educational purposes
Presenting problem: 13-year-old Tyler was referred for oppositional behavior at school and refusing to follow rules at home. His mother, Diana, described feeling "overwhelmed and undermined."
Family structure: Diana (38, single mother) and Tyler (13) lived with Diana's mother, Patricia (62). Diana's father had died five years earlier. Diana's ex-husband, Mark, had minimal involvement with Tyler since their divorce when Tyler was 4.
Structural genogram revealed: A classic cross-generational coalition. Patricia had taken over executive parenting functions: she set Tyler's bedtime, managed his homework, and countermanded Diana's discipline. When Diana set a rule, Tyler appealed to his grandmother, who regularly overruled it. The parental hierarchy was inverted, with Patricia operating as the functional parent and Diana relegated to a sibling-like position in the household.
The genogram also revealed this was a multigenerational pattern. Patricia had similarly undermined her own husband's authority with the children when he was alive, maintaining an enmeshed mother-children subsystem with a disengaged father on the periphery.
Structural intervention: The therapist used the genogram to help Patricia see the pattern across generations and restructured the hierarchy by strengthening the parental subsystem boundary around Diana. Sessions focused on Diana and Patricia negotiating a clear division of authority, with Diana as the primary parent and Patricia in a supportive grandparent role. Tyler's oppositional behavior decreased significantly once the hierarchy was clarified.
How to Create a Structural Genogram with GenogramAI
Build the Family Map
Describe the family to GenogramAI's AI assistant, including who lives in the household, key extended family members, and the presenting problem. The AI generates the basic structure, including household composition and generational layout.
Add Structural Annotations
Use GenogramAI's relationship tools to map boundary types, coalitions, and hierarchy patterns. Mark enmeshed relationships with fused lines, disengaged relationships with distant lines, and conflictual relationships with jagged lines. Add notes about power dynamics and subsystem membership.
Identify Structural Dysfunction
Review the completed genogram for hierarchy inversions, boundary violations, and cross-generational coalitions. Look for multigenerational patterns: is the current dysfunction a repetition of structural problems from previous generations? Use findings to plan structural interventions.
Frequently Asked Questions
What is a structural family therapy genogram?
A structural family therapy genogram adapts the standard genogram to emphasize the concepts central to Salvador Minuchin's Structural Family Therapy: subsystem boundaries (rigid, diffuse, or clear), family hierarchies, coalitions, triangulation, parentification, and the overall organizational structure of the family. It visualizes who holds power, who is enmeshed with whom, and where boundaries are dysfunctional.
How do you show boundaries on a genogram?
Boundaries are shown using different line types drawn around subsystems: solid thick lines for rigid boundaries (little permeability between subsystems), dotted lines for diffuse boundaries (enmeshment, poor differentiation), and clear straight lines for healthy boundaries. These are drawn around groupings of family members to show the parental subsystem, sibling subsystem, and any cross-generational coalitions.
What is a parentified child on a genogram?
A parentified child is a child who has been elevated to a parental role, taking on caregiving responsibilities for siblings or even for the parents themselves. On a structural genogram, this is shown by placing the child within or adjacent to the parental subsystem rather than the sibling subsystem, often with an arrow indicating the reversal of the caregiving hierarchy.
How does triangulation appear on a genogram?
Triangulation occurs when two family members in conflict draw a third member into their dynamic to reduce tension. On a structural genogram, triangulation is shown with specific relationship lines: a coalition line between two members and a conflictual line with the excluded member. The classic example is a parent aligning with a child against the other parent.
What is the difference between enmeshment and disengagement?
In Minuchin's model, enmeshment refers to diffuse boundaries where family members are overly involved in each other's lives, with little individual autonomy. Disengagement refers to rigid boundaries where members are isolated and disconnected. Most healthy families fall between these extremes. Genograms can show both patterns using boundary line types and relationship indicators.
