NEO Personality Inventory — Revised
The NEO PI-R is a comprehensive 240-item self-report personality assessment that measures five major personality dimensions and thirty lower-order facets. Developed by Paul Costa and Robert McCrae in the early 1990s, it operationalizes the Five-Factor Model of personality—one of the most empirically validated trait taxonomies in psychological science. The measure has become the gold standard for personality assessment in clinical, research, and occupational settings.
