RIASEC and HEXACO: Is there something new in the interest-personality relation?

This paper explores the relation between RIASEC model of interests and new HEXACO model of personality (Lee & Ashton, 2004). Six HEXACO personality traits – Honesty/humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness and Openness to experience – were recovered in a number of cross-cultural lexical studies of personality structure and represent a reorganization of well-known Five-Factor model of personality. The main departure from Five Factor model is the inclusion of additional personality dimension of Honesty/Humility and a bit different meaning of Emotionality and Agreeableness dimensions. Therefore we were interested to explore the predictive value of newly introduced personality dimensions for RIASEC types. We applied measures of interests and personality to samples of university students (N=339) and employed adults (N=263). As a measure of six RIASEC types we used Occupational Preference Scale OPS, a shorter form of Pictorial and Descriptive Interest Inventory (PDII, Šverko & Babarović, 2010) in which respondents estimate liking of 48 presented occupations. As a measure of HEXACO personality traits we used HEXACO-PI-(R), the 100-item version (Ashton & Lee, 2008) in which each personality dimension is represented with 4 personality facets. We also applied The International Personality Item Pool IPIP (50-item version) as a measure of the Big Five personality domains. All instruments showed good psychometric properties. We found interesting pattern of relations among RIASEC types and HEXACO traits and facets. On the trait level, we found Honesty/humility positively related to Social interests and negatively to Enterprising, as well as Openness to experience positively related to Investigative and Artistic interests, and Emotionality to Social. We also explored predictive value of both HEXACO and IPIP personality traits for RIASEC types. We observed that Artistic, Social, Enterprising and Investigative types were better accounted for with personality dimensions than Realistic and Conventional types, and that HEXACO traits explained greater percent of variance of RIASEC types than IPIP traits did. As these results were mostly invariable across two different subsamples, we comment the possibility of HEXACO usage in the field of vocational counseling.
