Abstract

The aim of the present study was to examine relationships of five-factor personality traits and intelligence with vocational interests. Predictive value of five-factor personality traits and intelligence on six vocational interests included in Holland’s typology as well as on their higher order dimensions are examined. An attempt to cluster subjects into meaningful groups on the basis of their scores on RIASEC questionnaires was also made. The research was carried out on 132 workers from one of the leading Croatian companies for food production and distribution.
In order to examine the predictive value of five-factor personality traits and intelligence on vocational interests as criterion variables, several hierarchical regression analyses were performed. In the first group of these analyses, five-factor personality traits were entered as predictors in the first step, while in the second group of the regression analyses, intelligence was entered in the first step as a predictor variable. The results obtained show that social and enterprising interests are predicted only by personality traits, realistic and conventional only by higher intelligence, while investigative and artistic interests are predicted both by personality traits and higher intelligence. Extraversion is a single significant predictor of social and enterprising interests, while openness significantly predicts investigative and artistic interests.
Factor analysis of vocational interests on a sample of this research yields a two-factor structure. Artistic, social, enterprising and conventional interests were most highly saturated with the first, while realistic and investigative interests were with the second factor. The results of hierarchical regression analyses show that extraversion is a single significant predictor of the first, while openness and intelligence are positive predictors of the second factor.
Clustering the subjects on the basis of their scores obtained on vocational interests shows that they could be meaningfully grouped into the two clusters. The first cluster includes subjects with generally higher scores and the second with generally lower scores on all vocational interests. The results of binary logistic regression show that openness and intelligence significantly discriminate the two groups of subjects.
