The House-Tree-Person Test is a projective drawing test used to assess a person's personality and unconscious thoughts and feelings. Specific details in the drawings of a house, tree, and person are analyzed, such as the size and placement of elements. For example, an overly large roof may indicate schizophrenia, while truncated tree branches could suggest feelings of inadequacy. Interpretations are also made based on characteristics like pencil pressure, line quality, and inclusion or omission of certain body parts or other features. The test is particularly useful for populations that may have difficulty with verbal tests due to limitations in education, language skills, or physical ability.
