California Psychological Inventory

The California Psychological Inventory (CPI) is a self-report personality test designed to assess personality characteristics in "normal" individuals. Unlike some other personality inventories, the CPI was developed specifically for use with people who do not have significant psychological issues. It measures variables such as sociability, self-control, flexibility, and tolerance.1

The CPI was developed using peer nominations, differing from methods that rely on expert judgment. It has undergone revisions, such as one in 1987, to improve clarity and update content. Personality inventories like the CPI are used in various settings, including clinical diagnoses, employee selection, and psychological research. They aim to objectively score responses to questions about an individual's behavior to characterize their personality.12
