Factor structure of the Vocational interest models of Roe and Holland

Abstract

Analyses of interscale relations in 235 college students for the Vocational Preference Inventory and Vocational Interest Inventory, based on interest models of Holland and Roe, respectively, suggest that the twodimensional, circular configuration of occupational or personality types may be an oversimplification which impedes the understanding of the structure of vocational interests. For both interest models four orthogonal dimensions seem necessary to capture interindividual variability: Social vs. Technical, Organizational vs. Outdoor, Science vs. Business, and Artistic.
