title: Self- and other-reports of traits from the five-factor model: relations to personality disorder.
abstract: The current study used a psychiatric sample (N = 69) to examine: (1) the correspondence between self- and other-reports of general personality, as measured by the Five-Factor Model (FFM; Costa & McCrae, 1990), and personality disorder (PD) traits, as measured by a structured interview, (2) the relations between these two sets of ratings (FFM and PD traits) and consensus ratings of PD and impairment, and (3) the incremental validity of other-rated personality scores. Agreement between raters for the five domains of the FFM ranged from .23 (agreeableness) to .71 (openness); for the PD traits agreement ranged from .37 (avoidant) to .69 (antisocial). At both the domain and facet level, the personality profiles reflected in the correlations between the FFM scores and PD criteria were consistent across raters with the exception of narcissistic PD. Substantial evidence was found for the incremental validity of other-rated personality scores, with these ratings accounting for an additional 8 to 20% of the overall variance in PD features. The other-rated FFM scores also accounted for more variance in consensus ratings of impairment in the domains of romance, work, and social relations.
