ABSTRACT We examine two issues linking personality pathology and judgment of traits within the Five-Factor Model of personality. We hypothesize that pathology moderates self-other agreement—“target” participants with pathology should be less judgable than participants without pathology. In addition, we hypothesize that pathology could partially produce agreement across a variety of traits, particularly those traits fundamental to the pathology. In an adolescent sample including a group with Conduct Disorder (CD) and a Control group, we examine agreement between adolescents' self-reports and their mothers' informant reports. Using trait-centered and person-centered perspectives, we find support for both hypotheses. Results have implications for understanding the processes affecting personality judgment, for increasing integration of traditional personality research and personality pathology, and for personality assessment.
