California Psychological Inventory (CPI)

The California Psychological Inventory (CPI) is a psychological assessment that is a self report measure of behavior and personality. It consists of 434 true/false questions and identifies personality characteristics, traits, and thinking styles in individuals who take it. It is commonly used in workplace settings to predict how well someone will interact with others. There are 20 different scales of personality that are measured in this test including sociability, independence, empathy, self-control, tolerance, and dominance.

Some example questions are: "It is hard for me to sit still and relax", "I read at least 10 books a year", and "People often expect too much of me". This assessment has built in control questions that prevent a person from "faking good" and answering dishonestly.
