Comparison of Native American Navajo Bender-Gestalt performance with Koppitz and SOMPA norms

The authors compare Koppitz error scores of a large group of referred Navajo children with the 1974 Koppitz and SOMPA total sample norms. Results suggest that the 1974 Koppitz and SOMPA white norms may have utility as an aide to psychological assessment of Native American Navajo children. Recommendations are made regarding effective methods of differential diagnosis and for further validation studies to confirm the relevance of Koppitz and SOMPA norms as they are used with Navajo children.
