Bernreuter Personality Inventory
The Bernreuter Personality Inventory is a personality test developed by Robert G. Bernreuter in 1931 measuring general personality. It is sometimes cited as the first multi-scale personality questionnaire. It consists of 125 yes or no question which yield six scores: neurotic tendency, self-sufficiency, introversion-extraversion, dominance-submission, sociability, and confidence. A 1936 survey of members of the American Psychological Association found that the Bernreuter Personality Inventory was the most well known psychological test.
