The California Psychological Inventory (CPI) also known as California Personality Inventory[1] is a self-report inventory created by Harrison G. Gough and currently published by Consulting Psychologists Press. The text containing the test was first published in 1956, and the most recent revision was published in 1996. It was created in a similar manner to the Minnesota Multiphasic Personality Inventory (MMPI)—with which it shares 194 items. But unlike the MMPI, which focuses on maladjustment or clinical diagnosis, the CPI was created to assess the everyday "folk-concepts" that ordinary people use to describe the behavior of the people around them.[2]
