Sažetak
The aim of this study was to explore heritability of personality traits in Croatian and in Serbian population using the twin design. The Croatian sample consisted of 339 twin pairs (105 MZ and 234 DZ), aged between 15 and 22. The Serbian sample consisted of 211 twin pairs (73 MZ and 138 DZ), aged between 16 and 60. In both samples, personality traits were organized using Five-factor Model framework and assessed by NEO personality scales in self-report form. In Croatian sample the shorter NEO-FFI questionnaire was used, while in Serbian sample data were available for the longer NEO-PI-R version of the questionnaire. Analyses were performed using Mx software with two data sets analyzed as separate groups.Results indicate that personality traits are moderately heritable both in the Croatian and in the Serbian populations, with slightly higher estimates in the Croatian sample. However, while Croatian data suggest possible nonadditive genetic effect and no effect of the shared environment, Serbian data suggest probable additive genetic influence and possible shared environmental influence. Since both samples are relatively small, in order to obtain more conclusive results about cultural differences, additional data are needed.
