Personality-related problems in living: An empirical approach

A proposal for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-V) is to separate the diagnosis of mental disorder from the assessment of impairment or disability. A separation of the assessment of traits and impairment is consistent with the five-factor model (FFM) procedure for the diagnosis of a personality disorder, which first assesses for the presence of personality traits, followed by an assessment of impairments associated with a particular trait elevation. The current study tested the hypothesis that the FFM has specific implications with respect to the 3 fundamental components of personality disorder as provided in the American Psychiatric Association's (2000) diagnostic manual, concerning social impairment, occupational impairment, and distress. These hypotheses were confirmed in a sample of 79 persons who were currently or recently in psychological treatment. Implications of the findings for a conceptualization of personality disorder and future research are discussed.
