House–Tree–Person
In the house-tree-person test, the client is asked to make a drawing that includes a house, a tree and a person, after which the therapist asks several questions about each. For example, with reference to the house, Buck (1984) wrote questions such as, "Is it a happy house?" and "What is the house made of?" Regarding the tree, questions include, "About how old is that tree?" and "Is the tree alive?" Concerning the person, questions include, "Is that person happy?" and "How does that person feel?"
The house-tree-person test is a projective personality test, a type of exam in which the test taker responds to or provides ambiguous, abstract, or unstructured stimuli (often in the form of pictures or drawings). It is to measure aspects of a person's personality through interpretation of drawings and responses to questions, self-perceptions and attitudes.
