The study investigated the construct validity of the California Psychological Inventory person-orientation and value-orientation scales by examining their relationships to Eysenck's extraversion and neuroticism dimensions. Both inventories were administered to 211 undergraduate students. While there was obviously a moderate relationship of .51 to .54 between the Person Orientation scores and Eysenck's extraversion, only about 25% of the variance in each of the two scales was common. The magnitude of the relationship between the Value Orientation scale and neurotic-extravert/stable-introvert group membership was slightly greater.
