Abstract

The purpose of this thesis was to determine whether the NEO Personality Inventory-Revised (NEO PI-R) could account for significant variance within a measure of personality developed for the intellectually disabled (i.e., the Reiss Profile of Fundamental Motives), as well as to consider their comparative validity. The NEO PI-R and the Reiss Profile of Fundamental Motives were administered to 127 undergraduate students in conjunction with the Personality Research Form (PRF) and the Behavior Report Form (BRF). The NEO PI-R was able to account for a substantial amount of variance in the Reiss Profile scales, and the Reiss and the NEO accounted for approximately equivalent amounts of variance in the PRF and BRF. Implications for general personality research as well as additional research with a sample of adults with intellectual disability are discussed.
