Abstract [en]

The Five Factor Model (FFM) with its 30 facet traits is proposed as a universal basis for PD (Personality Disorders). For instance, based on the FFM-count method (Miller et al., 2005), the disposition for Paranoid PD can be calculated by a validated set of FFM sub-traits: N2 + E1_R + E2_R + O4_R + O6_R + A1_R + A2_R + A3_R + A4_R + A6_R. Using a comprehensive open-source representation of FFM (IPIP-NEO-120; Johnson, 2014), we explored age and sex differences in the 10 DSM-IV PD categories with the presumably largest US sample to date (N = 320,128). The results showed differences of up to ½ SD in all PD categories across age-groups, as well as clear gaps between sexes. For example, the largest decline with age, as well as differences in sex, was seen in Antisocial PD. Also, interaction effects between age and sex could be seen in Schizoid and Schizotypal PDs. The present study presents tentative support for personality trait theory as a basis for psychopathology, and updated benchmarks on the scope and size of sex and age differences in PD dispositions in the community.
