Family history assessment of personality disorders: II. Association with measures of psychosocial functioning in direct evaluations with relatives.
To test the convergent validity of the Family History Interview for Personality Disorders (FHIPD), as well as the general utility of informants' reports of personality disorders, we explored the relationship between proband informant reports of Axis II diagnoses on the FHIPD and relative reports of various indices of psychosocial adjustment. Subjects were the first degree relatives (n = 454) of 224 probands participating in a family study of mood and personality disorders. Relatives provided information on the Structured Clinical Interview for DSM-III-R (SCID), the Personality Disorder Examination (PDE), and other variables reflecting aspects of psychosocial dysfunction that are common in personality disorders. Proband informants were interviewed about their relatives using the FHIPD Proband informant reports of personality disorders on the FHIPD were associated with a variety of forms of psychosocial dysfunction as determined in direct assessments with the relatives, even for those with no diagnosable Axis II psychopathology dysfunction as determined in direct assessments with the relatives, even for those with no diagnosable Axis II psychopathology on direct interview. These results support the convergent validity of the FHIPD, and suggest that informants may provide important information on Axis II psychopathology that is not obtained from direct interviews with the subjects themselves.
