Genogram for my classmate is here. The genogram provides a graphic depiction of the family's structure and history to the play therapist. The Intake form contains an example of the formats and symbols used to express various familial relationships.The genogram is a popular way for determining who belongs in a family and what roles essential family members perform in relation to one another. The traditional genogram comprises the biological family; however, genograms can also include individuals who serve a specific function within the family.
