Phenotypic And Genetic Relationships Between Vocational Interests And Personality, Julie Harris, Philip Vernon, Andrew Johnson, Kerry Jang
Andrew M. Johnson
Relationships between personality and vocational interest factors were examined at the phenotypic and genetic levels. Twins and siblings (N = 516) completed self-report personality and vocational interest scales. Following factor analyses of each scale, five personality and six vocational interest factors were extracted. At the phenotypic level, correlations between personality and vocational interests ranged from zero to .33. Heritability estimates of the scales showed that genetic components accounted for 0–56% of the variance for the vocational interest factors and 44–65% for the personality factors. Genetic correlations between the two areas ranged from zero to .50. The results suggest that personality …

Most modern theories of personality are structured hierarchically, with broad higher-order dimensions predicting narrower trait-level variables. This approach is necessarily reductionist, proposing to summarize the majority of trait-specific variability with a smaller number of larger dimensions. Not surprisingly, therefore, significant research has been directed to determining what might be considered to be the most basic dimensions of personality—both with regards to the identification of how many factors are needed to describe personality, and what these factors might be called (Costa & McCrae 1992a; [29] and [30]; Tupes & Christal 1992; Zuckerman 1992; [121] and [122]. While these omnibus factors of …
