• Resumen

  • The IPIP-NEO () is a 300-item inventory that measures constructs similar to those in the NEO Personality Inventory (NEO PI-R; ). Despite evidence for its reliability and validity, the IPIP-NEO is even longer than the original 240-item NEO PI-R. This article details the development of a 120-item version of the IPIP-NEO from an Internet sample (N = 21,588) and the subsequent testing of its psychometric properties in Eugene-Springfield community sample (N = 481), two additional large Internet samples (Ns = 307,313 and 619,150) and a local sample (N = 160). Results indicate that the psychometric properties of the 120-item IPIP-NEO compare favorably to the properties of the longer form.
