Genograms for Therapy

Why therapists draw genograms

The genogram comes out of Murray Bowen's family systems theory and was standardized for clinical use by Monica McGoldrick and Randy Gerson in Genograms: Assessment and Intervention. The premise: presenting problems rarely belong to one person. Anxiety, addiction, estrangement, and loss run in patterns across generations, and a three-generation map makes those patterns discussable. Drawing one also happens to be a strong joining intervention — clients organize their own story while you diagram it together.

What to look for once it's drawn

• Triangles. Bowen's core unit: when tension rises between two people, a third gets pulled in. In the example above, the fused mother–daughter line beside the conflictual father–son line is a textbook triangle candidate.
• Cutoffs. The broken line to the deceased grandfather marks contact that ended before death — unresolved attachment that often resurfaces in the next generation's relationships.
• Fusion vs. closeness. Three lines are not a stronger version of two. Fusion (enmeshment) is low differentiation — the relationship where one person's anxiety instantly becomes the other's.
• Repetition across generations. Divorce over divorce, a firstborn estranged in each generation, losses at the same age. Repeats are hypotheses, not verdicts — but they focus the questions.
• Anniversary dates. Birth and death years let you notice when a client's crisis lands on the anniversary of a family loss.

Using genograms in treatment, practically

Intake (sessions 1–3): a rough genogram on paper or screen while gathering history — names, ages, households, major events. Fifteen minutes, done with the client watching. Middle phase: add the emotional layer collaboratively; asking "what kind of line goes between you and your mother?" externalizes the relationship and lowers defensiveness. Later: revisit and redraw — lines that change over treatment are progress you can literally show. Couples work adds both families of origin on one page; the moment partners see they married into each other's patterns is often the session that lands.

A note on records and privacy

A genogram of a real client is clinical material. This tool keeps everything in your browser — nothing is uploaded — and the exported PDF carries a title block and legend so it can stand alone in a chart. Use initials rather than full names if your documentation policy calls for it.

Start from the family therapy template, check any unfamiliar line against the symbols reference, or read the worked examples first.
