Module 1 "Understanding" — Lesson 28 · Reading time approx. 11 min

A genogram shows a family on a single day — but families never stand still. This lesson shows how genograms can be dated, where symptoms typically emerge, and why a model from the 1980s can only be read today with caution.

Why symptoms emerge at transitions

A genogram looks like a photograph. People, lines, a single point in time. What it does not show on its own: that every family in it is moving through phases, and that strain accumulates at particular points along that movement — not scattered randomly across time.

Betty Carter and Monica McGoldrick set out a stage model for exactly this in "The Expanded Family Life Cycle," still the most widely used map of that movement. The core idea: a family passes through several clearly distinguishable stages, and each stage ends with a transition task — a reorganization of relationships, roles, and rules that must be completed before the next stage can begin on solid footing.

The central finding: symptoms cluster not within the stages themselves, but at their transitions. A young adult leaving home, a marriage, the birth of a child, the death of a grandparent — events like these force a system to reorganize. When that reorganization fails to happen in time, or fails to happen fully, it often shows up not as an open crisis but as a symptom in one individual: a child who suddenly struggles at school, an adult with newly onset complaints, a couple who erupt into conflict after years of quiet.

That is the real payoff of the stage model for genogram work: the same picture — the same boxes, the same lines — can be read in entirely different ways depending on which stage you hold in mind. Without this lens, a genogram remains a structure. With it, it becomes a story caught at a particular moment.

Hypothetical case example: A family of four comes in for outpatient counseling. The older son moved out a year ago. The maternal grandmother was widowed six months ago. And for the past three months, the younger son has been struggling at school. Three events that, at first glance, have nothing to do with one another — they involve different people at different points in the system. No one in the family would have connected them on their own. The genogram does not reveal the connection by itself either. You have to know what you are looking for. This example carries through the whole lesson.

The six stages according to Carter & McGoldrick

The classic model distinguishes six stages, each with its own transition task. The sequence is meant as an ideal type, not a prescription.

1. Leaving home — the young adult becomes independent. The task: taking on emotional and financial responsibility for oneself without cutting off contact with the family of origin. Anyone who skips this step, or is forced through it too fast, tends to carry the unresolved separation into the next stage.

2. The new couple — two systems join. The task: committing to a system of their own while renegotiating the relationships to both families of origin so that the new partner has a place in them. This is where it gets decided whose Christmas tradition holds and whose surname stays — small questions carrying outsized symbolic weight.

3. Families with young children. The task: making room for children within the couple system, redistributing childrearing, household, and financial responsibilities, and drawing the grandparent generation into its new role. Many couples experience precisely here the first noticeable drop in time together as a pair.

4. Families with adolescents. The task: making the parent-child boundary more permeable to allow the adolescent greater autonomy, without abandoning structure altogether. At the same time, the parents' own concerns move back into the foreground — midlife, career, and often a first look at their own parents' growing need for care.

5. Launching children and moving on. The task: renegotiating the couple system as a twosome again, building an adult-to-adult relationship with the grown children, integrating children-in-law and grandchildren — and often, at the same time, coping with illness or death in the parents' own generation. This stage is compressed: several transitions frequently fall within the same window, which is exactly what makes it so worth reading closely in a genogram.

6. Families in later life. The task: maintaining one's own capacity to act despite physical decline, accepting a changed role relative to the middle generation, making room for the wisdom of aging, and preparing for loss — of a partner, siblings, peers, and, in the end, one's own death. Anyone in this stage who is still called on to care for their own parents while their own strength is failing stands in two transition tasks at once — a pattern that often shows up in a genogram as overlapping years of caregiving and dying.

Between the stages there is no clean break, only overlap. The fourth and fifth stages, for instance, run in parallel for years in many families: a younger sibling is still in the middle of adolescence while the older child has already left home. The model therefore describes not a chain of states but a movement that can be at very different points in different parts of the same family at once.

Six stages, six transitions. No family completes one transition task before the next begins — and it is exactly in that overlap that the model's diagnostic value lies.

Making the genogram dateable

A genogram that shows only people and relationships cannot answer the question of stage. For that, it needs years.

Concretely, that means entering birth years wherever possible. Marriage years, separation years, years of death. Dates of leaving home, where known. Not as an end in itself, but because it is only by placing these dates side by side that you can read off which subsystem is in which stage — and whether several transitions coincide in time.

A dated genogram answers a different question than an undated one. Without years, you see: this family has an adolescent, a widowed grandmother, an older son who has moved out. With years, you see: the move, the widowhood, and the symptom all fall within a twelve-month window. That is not a coincidence you happen to miss — it is a pattern that stays invisible without dating.

In practice, full precision is rarely needed. A decade, an "approximately," a "before the younger child was born" is often enough. What matters is not accuracy to the exact year, but that some timeline emerges in the picture at all, against which events can be located.

In practical terms: wherever GenoEasy allows years to be entered for people and partnerships, they should be entered even when only estimated — an estimated year in parentheses is still more informative than a blank field. More important than any single number, in any case, is the distance between numbers: if the move, the separation, and the death lie years apart, the genogram tells three separate stories. If they lie months apart, it tells one.

Three questions to ask of the finished genogram

With a dated genogram in front of you, three questions turn the picture from a snapshot into a movement.

First question: which stage is each subsystem in? A family is rarely in only one stage. The parents may already be in the launching stage while a late-born child is still going through adolescence. Grandparents are often simultaneously in the final stage. This simultaneity is the norm, not the exception — and it explains why needs within the same family can feel so different from one member to the next.

Second question: which transition is overdue? Sometimes the genogram shows a stage that, on paper, should long since have ended. A "child" who is 34 and still living at home, still financially dependent. A couple who, five years after the children moved out, have clearly not found their way back to each other. This question is not looking for faults but for the point where a necessary reorganization failed to happen — and it is also the question that calls for the most caution, because "overdue" is easily mistaken for "wrong." The section on critical perspective further below returns to this point.

Third question: what coincided in time? Here the dating from the previous section comes into play. Carter and McGoldrick distinguish two kinds of stress that can overlap in a genogram.

Horizontal stressors run along the axis of time — they are the predictable transitions of the life cycle itself (leaving home, marriage, birth, aging) as well as unpredictable ruptures that can strike at any point: an accident, a sudden illness, an early death, a job loss.

Vertical stressors, by contrast, run down through the generations — family patterns, core attitudes, unspoken rules, taboos, labels, and expectations handed down from one generation to the next, often without anyone naming them.

Tension builds most where a horizontal and a vertical stressor land on the same point in the system at the same time. In the case example: the older son's move is a horizontal stressor — a normal, expectable transition. The grandfather's death is horizontal too, but unpredictable. If a vertical pattern in the same family adds to that — say, a family attitude, carried across generations, that losses are not discussed openly — then it becomes clear why it is the younger son who stays behind and carries the symptom: he stands exactly where both lines cross.

Critical perspective: a model from a particular time and class

The six-stage model, in its classic form, emerged from the American middle class of the 1980s. It implicitly describes one particular life path: heterosexual first marriage, biological children of one's own, a sequence of leaving home, forming a couple, parenthood, the children leaving home, old age — in that order and without major disruptions.

That path is one among many today, not the default. Blended families formed after multiple separations, single-parent families from the outset, childless couples, late parenthood well outside the classic window, families with a migration history in which several stages of different family-of-origin systems unfold at once — for all of this, the original six-stage model alone is not enough. Carter and McGoldrick themselves therefore added expanded versions of their work that take in exactly this diversity, rather than treating it as a deviation.

The stages are a map, not a verdict. Read normatively — "this family is behind on separation," "this couple skipped the couple stage" — the model becomes a yardstick it never claimed to be. A family that departs from the classic sequence is not, by definition, a cause for concern. What is worth noting is when a necessary reorganization fails to happen and a system visibly suffers under that mismatch — regardless of how far the family's shape departs from the model.

In the case example, a normative reading would say: "The son should have moved out long ago." The appropriate reading instead is: three transitions coincided within a short span, and the system had no chance to work through them one at a time. That is a finding about time pressure, not about a family running late.

This matters especially for family forms the original model never anticipated. In a blended family formed after two separations, two or three life cycles may be running at once, each with its own transitions and its own pace — a child who moves between two households effectively stands in two systems at once, in different stages in each. In a family with a migration history, the family of origin in another country may be moving through a completely different stage than the newly formed family in the new place of residence, the two never running in sync. The model does not break down here — it simply has to be read consciously for what it is: an orientation for the most common case, not a template for every case.

Summary

At first glance, a genogram shows only people and their relationships. Only the dimension of time — years, stages, transitions — turns it into a tool that explains why a symptom appears just now, and in just this person.

Carter and McGoldrick's six stages offer an orientation for that: each stage ends with a transition task, and symptoms cluster where that task is not resolved in time — especially where a horizontal stressor meets a vertical family pattern. In the case example, it was the overlap of a move, a widowhood, and an unspoken family rule about how to handle loss.

The model dates the genogram; it does not rule on right and wrong. Read as a map rather than a norm, it gives you one more question to ask of every genogram: not only who belongs to a family, but what movement it is caught in right now.
