Personality traits are prominent aspects of personality that are exhibited in relatively consistent ways across time and across situations. Personality traits influence self and interpersonal functioning. Depending on their severity, impairments in personality functioning and personality trait expression may reflect the presence of a personality disorder.
Personality disorder—trait specified (PD-TS) is defined by significant impairment in personality functioning, as measured by the Level of Personality Functioning Scale and one or
more pathological personality trait domains or facets.
