In Nederland en Vlaanderen wordt veelvuldig gebruikgemaakt van interessevragenlijsten bij (studie)loopbaanvraagstukken. In tegenstelling tot de populariteit van deze vragenlijsten in de praktijk wordt er relatief weinig wetenschappelijk onderzoek gedaan naar beroepsinteresses in het Nederlandse taalgebied. In dit artikel wordt het Sferische model van beroepsinteresses geïntroduceerd, evenals de Nederlandse vertaling van de Personal Globe Inventory(PGI; Tracey, 2002) als een meetinstrument voor dit model. Het Sferische model voegt Prestige-interesse als derde interessedimensie toe aan de traditionele tweedimensionale circumplex van beroepsinteresses. Verder deelt het Sferische model de traditionele circumplex op in acht in plaats van zes interessegebieden. Aan de hand van 12 steekproeven uit Nederland en Vlaanderen is de kwaliteit van de PGI-lang en PGI-kort onderzocht. De psychometrische kenmerken van de Nederlandse vertaling van de PGI-lang en PGI-kort bleken acceptabel tot uitstekend: de items van de vragenlijst laadden grotendeels op de bedoelde schalen, de schalen correleerden volgens een circumplexordening, en de betrouwbaarheden waren acceptabel. De grootste sekseverschillen werden gevonden op mensen-versus-dingen interesse en Prestige-interesse was iets sterker bij jongere deelnemers en hoogopgeleiden. Toekomstig onderzoek kan zich richten op het beter begrijpen van de inhoud van Prestige-interesse en de betekenis van deze dimensie voor (studie)loopbaanprocessen en -uitkomsten.

Summaries

In the Netherlands and Flanders, vocational interest inventories are frequently used to address (study) career dilemmas. In contrast to their popularity in practice, in the Dutch language region, there is relatively little research looking at vocational interest(s) (inventories). This article introduces the Spherical Model of Vocational Interests and the Dutch translation of the Personal Globe Inventory(PGI; Tracey, 2002), a measure for this model. The Spherical Model adds Prestige interests as a third dimension of vocational interests to the traditional two-dimensional circumplex. Additionally, the Spherical model splits the traditional circumplex in eight, rather than six, interest domains. The quality of the Dutch PGI was investigated with 12 samples. The psychometric qualities of the full Dutch PGI and its short version appeared to be acceptable to exemplary: the items of the scales largely fitted with the appropriate scales, the scales correlated according to the expected circumplex order, and the reliabilities were acceptable. The largest gender difference was found on the People-versus-Things dimension. Additionally, younger and more educated people scored higher on Prestige interests. Future research could further the understanding of the content of the Prestige dimension and how this dimension affects (study) career processes and outcomes.

STRUCTURE OF VOCATIONAL INTERESTS IN MACEDONIA AND CROATIA – EVALUATION OF THE SPEHRICAL MODEL

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.

Perceptions of Vocational Interest

The current study investigated how self- and other-ratings of vocational interests converge among student–parent dyads. Using the Personal Globe Inventory–Short, we obtained data from a pooled sample of 271 (high school senior and university) student–parent dyads. Participants rated their own vocational interests and those of the other dyad member. First, profile correlations revealed high levels of self-other agreement, moderate levels of assumed similarity, and low levels of similarity and reciprocity in vocational interests. These correlations are highly similar to those found in personality research. Second, profile elevation showed a reversed pattern compared to interest perceptions, with high levels of self-other agreement and moderate levels of assumed similarity, indicating that profile elevation may mostly be an artifact/rater bias and not a substantive factor. Ipsatization of the vocational interest scales somewhat reduced profile elevation bias. Third, same-gender dyads overestimated their similarity in vocational interests more than different-gender dyads.

Evaluation of the hexagonal and spherical model of vocational interests in the young people in Serbia and Bulgaria

The aim of this study was to validate Holland?s hexagonal and Tracey?s spherical model of vocational interests in young adults in Serbia and Bulgaria. To this end, 1250 participants, 560 from Serbia and 690 from Bulgaria, filled in Serbian and Bulgarian versions of the Personal Globe Inventory (PGI, Tracey, 2002). Hubert and Arabie?s randomization test of hypothetical orders, multidimensional scaling with fixed coordinates, Myors test and exploratory factor analysis were used. The results showed that the hexagonal and spherical models well explained the structure of vocational interests in both samples. The level of fit of the hexagonal model to the data obtained by using the PGI was generally higher than those established in the studies that used other Holland-based instruments. Furthermore, the levels of fit of both hexagonal and spherical model were in the same range like those obtained in previous studies in other countries. The results also pointed out a remarkable similarity in the structure of vocational interests in the Bulgarian and Serbian samples.
