Tested models of interests by examining the significance of disconfirmed ordinal predictions. Examined data regarding Holland's hexagonal model and Roe's circular ordering. Tested adequacy of the hierarchical model and compared significance of the disconfirmed predictions of the hierachical model to that of the hexagonal-circular model. (Author)

Tested the predictive validity of Holland's constructs of congruence and consistency defined according to the hierarchical model for the structure of interests. A follow-up study of adults tested as high school seniors showed the hierarchical and circular models are of similar efficiency in predicting occupational choice satisfaction. (Author/JAC)
