A note on some measures of profile agreement.
Profile similarity or agreement is increasingly used in personality research and clinical practice and has potential applications in many other fields of psychology. I compared 4 measures of profile agreement--the Pearson r, Cattell's (1949) r(p), McCrae's (1993) r(pa), and an intraclass correlation coefficient (double entry), ICC(DE)--using both broad factor and specific facet profiles. Matched versus mismatched self-ratings/other ratings on the NEO Personality Inventory-3 (McCrae, Costa, & Martin, 2005) were used as criteria. At the factor level, r(pa) and ICC(DE) were comparable, and both were superior to r(p) in distinguishing matched versus mismatched profiles. At the facet level, ICC(DE) was superior to the other coefficients. The Pearson r performed better than expected.
