≪Organizer Abstract≫
With its two-tiered approach, DSM-5 is a milestone moment in the assessment of personality and psychopathology: it is the first DSM featuring a model of maladaptive personality traits and a separate measurement of levels of personality functioning. A first study examines the impact of severity of personality impairment (i.e. level of personality functioning) on interpersonal processes in daily life. A second study initiates a more developmental focus by investigating age specific and neutral expressions of personality functioning in adolescents and adults. Next, a third study derives an empirically based set of personality facets for the DSM-5 trait model, examining the direct association of the facets and specific personality disorders. A fourth study shows associations between personality traits and disorders and conceptually-relevant MMPI-2-RF scales. Finally a fifth study applies a network analytical approach to uncover causal relations between symptoms and as such reveals comorbidity patterns within the existing nosology.
