The goal of the current paper was to explore the construct validity of the spherical and the hexagonal models of vocational interests by exploring the extent to which these models fit the data obtained on samples of Macedonian and Croatian university students. Croatian and Macedonian versions of the Personal Globe Inventory (PGI) were administered to a sample of 1367 student of various faculties in Croatia and Macedonia (737 participants from the Republic of Macedonia and 630 from Croatia). Results showed that the spherical and hexagonal models fit the data better than chance, and that these models explain substantial proportions of variance of vocational interest measures. Exploration of the factor structure of the obtained measures of vocational interest on the studied samples showed that the obtained structure generally corresponds to theoretical propositions. The obtained dimensions correspond to the latent space defined by Prediger’s dimensions and the dimensions of Prestige of the spherical model.
