Abstract
In this study, four humor styles (affiliative, self-enhancing, aggressive, self-defeating) were assessed in conjunction with a measure of the HEXACO model of personality, in order to gain greater insight into the etiology of these humor styles, and to situate them better in the framework of human personality. Participants were 664 monozygotic twin pairs and 522 dizygotic twin pairs from the United Kingdom who completed the Humor Styles Questionnaire and the HEXACO Personality Inventory. Univariate behavioral genetic analyses of the HEXACO revealed that individual differences in all of its dimensions were entirely attributable to additive genetic and non-shared environmental factors. Significant phenotypic correlations were found between many of the HEXACO factors and the four humor styles, and bivariate behavioral genetic analyses revealed that these correlations were themselves accounted for entirely by correlated genetic and correlated non-shared environmental factors. Our study adds to the literature validating humor as a personality construct and assessing its relations to psychological well-being.

In this study, four humor styles were assessed in conjunction with a measure of the HEXACO model of personality, in order to gain greater insight into the etiology of these humor styles, and to situate them better in the framework of human personality
I n addition to reporting the first behav ioral genetic inv estigation of the HEXACO model, our study assesses the phenotypic correlations betw een the four humor styles and the six dimensions of this model
I n addition to reporting the first behav ioral genetic inv estigation of the HEXACO model, the present study had tw o main goals: to determine the associations betw een the four humor styles and the HEXACO dimensions, in order to situate the humor styles in a more comprehensiv e personality structure, and to assess the potential etiology of humor styles in the context of this structure
Summary
Throughout most of the 20th century, little consensus existed regarding the structure of human personality (Lee & Ashton, 2004). Studies carried out in Hungarian and I talian hav e confirmed a fiv e-factor solution of human personality structure, but hav e defined the fifth factor as reflecting integrity and trustw orthiness rather than the conv entional intellect/imagination (e.g., De Raad & Szirmak, 1994; Di Blas & Forzi, 1998) Taking these results into account, Ashton and Lee (2001) proposed the HEXACO model of personality, w hich is composed of six distinct dimensions. Their rev iew , and the other inv estigations referred to abov e, how ever, did not include the sixth HEXACO factor of Honesty-Humility, w hich does not hav e a Big Fiv e analogue, and information on the genetic and/or env ironmental etiology of this factor is currently not av ailable
