The California Psychological Inventory is a 462-item true-false personality test published in 1957 by Harrison Gough. It measures personality traits and can predict outcomes such as delinquency, leadership ability, job performance, and college attendance. The test takes about an hour to complete individually or in a group setting. Scores are plotted on a profile to interpret personality characteristics and behaviors based on elevated or lowered scores across the test's 16 scales. The CPI demonstrates high reliability with test-retest correlations of around .90.
