Specific Personality Traits and General Personality Dysfunction as Predictors of the Presence and Severity of Personality Disorders in a Clinical Sample.

This study examined the associations of specific personality traits and general personality dysfunction in relation to the presence and severity ofDiagnostic and Statistical Manual of Mental Disorders(4th ed. [DSM–IV]; American Psychiatric Association, 1994) personality disorders in a Dutch clinical sample. Two widely used measures of specific personality traits were selected, the Revised NEO Personality Inventory as a measure of normal personality traits, and the Dimensional Assessment of Personality Pathology-Basic Questionnaire as a measure of pathological traits. In addition, 2 promising measures of personality dysfunction were selected, the General Assessment of Personality Disorder and the Severity Indices of Personality Problems. Theoretically predicted associations were found between the measures, and all measures predicted the presence and severity ofDSM–IVpersonality disorders. The combination of general personality dysfunction models and personality traits models provided incremental information about the presence and severity of personality disorders, suggesting that an integrative approach of multiple perspectives might serve comprehensive assessment of personality disorders.
