A hierarchical model for the structure of vocational interests is proposed. An interpretation of existing findings suggests that this model accounts for interrelations among the vocational interest fields better than other models. Implications of this model for vocational theory and some applications in vocational guidance are discussed. (Author)

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)
