The validity of two-scale pattern interpretation on the California Psychological Inventory

The validity of 2-scale pattern interpretation for the CPI was assessed within a college counseling service population. Groups representing high and low score combinations on the Dominance and Good Impression scales were constituted, and the self-descriptive adjectives from the Adjective Check List which differentiated these groups from a representative counseling service groups were determined. These clusters of self-descriptive terms were generally consistent with the personality types which would be anticipated, based on the combined meanings of high and low scores on the individual scales as evidenced by high matching accuracy of expert judges. These results provide gross validational support for 2-scale pattern interpreation on the CPI.
