A genogram (also known as a McGoldrick–Gerson study, a Lapidus schematic or a family diagram) is a pictorial display of a person's family relationships and medical history. It goes beyond a traditional family tree by allowing the user to visualize hereditary patterns and psychological factors that punctuate relationships. It can be used to identify repetitive patterns of behavior and to recognize hereditary tendencies.
Murray Bowen invented the concept of the genogram as part of his family systems model in the 1970s. Genograms were later developed and popularized in clinical settings by Monica McGoldrick and Randy Gerson through the publication of a book titled Genograms: Assessment and Intervention in 1985. Genograms are now used by various groups of people in a variety of fields such as medicine, psychiatry, psychology, social work, genetic research, education, and many more. Some practitioners in personal and family therapy use genograms for personal records and/or to explain family dynamics to the client. Few if any genealogists use them.
A genogram is created with simple symbols representing the gender, with various lines to illustrate family relationships. Some genogram users also put circles around members who live in the same living spaces. Genograms can be prepared by using a complex word processor, or a computer drawing program. There are also computer programs that are custom designed for genograms.
Genogram symbols will usually have the date of birth (and date of death if applicable) above, and the name of the individual underneath. The inside of the symbol will hold the person’s current age or various codes for genetic diseases or user-defined properties: abortions, still-births, SIDS, cohabitations, etc.
