The Weakness of Buck's House-Tree-Person (H-T-P) Assessment Test

The House-Tree-Person (H-T-P) was designed in 1947 by psychologist John N. Buck. The projective assessment was designed to provide information on personality characteristics and interpersonal relationships.

The H-T-P is an assessment that utilizes drawing a House a Tree and a Person. First the objects are drawn with pencil (achromatic) and then the same objects are drawn using color (chromatic).

But thus far there has not been evidence to support this proposition. He also thought that the H-T-P could serve as a pretest tool for entrance into schools,specialized training programs or employment positions. Validity and reliability evidence wo...
