The purpose of this study was to identify higher-order dimensions that explain the relationships among the Big 6 interest types and the Big 5 personality traits. Meta-analyses were conducted to identify an 11 × 11 true score correlation matrix of interest and personality attributes. Cluster analysis and nonmetric multidimensional scaling were used to identify 3 dimensions that explained relations among the 11 attributes: (a) Interests versus Personality Traits; (b) Striving for Accomplishment Versus Striving for Personal Growth, and (c) Interacting with People Versus Interacting with Things. Overall, results clarified the relationships among interests and personality traits by showing that 3 rather than 2 dimensions best explain the relationships among interests and personality traits.
