Discriminant Validity of NEO-PIR Facet Scales

Abstract
Two analyses were conducted to examine the discriminant validity of 30 facet scales from the Revised NEO Personality Inventory (NEO-PIR). To examine cross-observer validity of specific variance in the facet scales, partial correlations between self-reports and peer (N = 250) and spouse (N = 68) ratings on the facets were calculated, controlling for the five common factors. All 60 convergent partial correlations were positive, and 48 (80%) were significant. In the second analysis, Adjective Check List (Gough and Heilbrun, 1983) correlates of the facet scales were identified in a sample of 305 adults. Judges correctly matched scales to correlates in most cases, providing additional evidence for discriminant validity.
