Genograms In Family Assessment

What people get wrong about genograms

Genograms are family trees that track relationships, medical history, and behavioral patterns across generations. They are used primarily in therapy, social work, and some medical contexts. The tool looks simple on the surface because the symbols are standardized, but building one that actually tells you something useful takes practice and patience. Before I explain the process, here is the part most tutorials skip. A genogram is not just a diagram. It is a living document that changes as you gather more information from the client. You will redraw it. You will cross things out. You will add a squiggly line three weeks into treatment after the client mentions something their grandmother said during a family reunion. That is normal. It is supposed to happen that way. The basic symbols are standard enough. Squares for males, circles for females. Horizontal lines connect partners. Vertical lines drop down to children. Double lines between partners indicate close or high-conflict relationships depending on which convention your training used. Zigzag lines represent conflict. Dashed lines suggest emotional distance. A shaded symbol means the person has a diagnosed condition relevant to the assessment.

Here is what I found when I started using these regularly. Most people build the diagram from the identified patient outward. That approach usually produces garbage because the patient rarely has the most complete picture of the extended family. Start with the oldest generation you can access and work down. Call the oldest living relative first if possible. An aunt or uncle who attended the same family gatherings as the grandparents will remember things the parents forgot or chose to omit. This alone improved the accuracy of my early genograms significantly. I run into a specific problem with blended families and multi-generational households. The standard three-generation format breaks down quickly when half-siblings share only one parent, or when a grandparent raised a child who then became the primary caregiver for their own parent. I once had a client whose mother had been raised by her grandmother, then later became the legal guardian of her own sibling after their parents died. The standard drawing made it look like three separate nuclear families with no connection. I solved it by drawing two vertical lines dropping from the grandmother to each child and labeling which parent was biological and which was adoptive or legal guardian. Adding a small key at the bottom of the page prevented confusion later when other clinicians reviewed the diagram. The assessment portion happens while you are drawing, not after. Clients often reveal information while you are asking about aunts and uncles. They will volunteer details about alcoholism, depression, or infidelity when you are casually requesting the names of third cousins. Stay quiet during those moments. Let the information surface without pressing it. The genogram structure itself becomes a neutral space where uncomfortable history can be discussed without the intensity of direct questioning.

There are some things this tool simply cannot do well. Genograms do not capture financial dynamics, religious shifts, or cultural identity changes unless you add custom symbols and even then the diagram gets cluttered fast. They also tend to reproduce whatever biases the therapist brings to the session. If you ask about "family values" your genogram will look different than mine because we are filtering the same data through different assumptions. Writing down your own hypotheses alongside the diagram helps keep that in check. For people who want a ready-made symbol key and template, the Association for Family Constellations and Systems Therapy publishes a free PDF with the standard notation system. Many university psychology departments also host editable genogram templates on their counseling training pages. Search for "genogram symbol key PDF" and you will find multiple versions within minutes. Pick one and stick with it for consistency rather than switching between formats every time you start a new case. The real limitation of genograms is that they require the client to be willing and able to provide information. Clients with adopted backgrounds, estranged families, or trauma involving family members frequently hit a wall where there simply is no data to map. In those situations the empty spaces on the page are themselves meaningful. Mark them with a question mark or a slash rather than leaving them blank. The absence of information is part of the clinical picture.

I usually spend between 45 and 90 minutes on an initial genogram depending on family size and how much the client knows. Follow-up sessions where you add new information typically take about 20 minutes. The upfront investment pays off because once the diagram exists you can reference specific relationship patterns throughout the entire course of treatment without rebuilding context from scratch each time.
