Prediger's dimensional representation of Holland's RIASEC circumplex.

The authors conducted a structural meta-analysis to evaluate D.J. Prediger's (1982) 3-factor (1 general factor and 2 bipolar factors of data-ideas and things-people) representation of J. L. Holland's (1985a) RIASEC circumplex (including six personality types: realistic], investigative [I], artistic [A], social [S], enterprising [E], and conventional [C]). Confirmatory factor analysis and multidimensional scaling were applied to 77 U.S. RIASEC correlation matrices published between 1965 and 1989. Prediger's 3-factor model received support when predictions from his factor model conformed to the predictions from the circumplex
