Research assessing the relationship of the Five-factor model (FFM) of personality to personality disorder symptomatology has generally been consistent with theoretical expectations. Three exceptions, however, have been failures to confirm predicted associations of the NEO-Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992b) Conscientiousness scale with obsessive-compulsive personality disorder symptomatology, the NEO-PI-R Agreeableness scale with dependent symptomatology, and the NEO-PI-R Openness scale with schizotypal symptomatology. It was the hypothesis of this study that these findings might be due in part to a relative emphasis on adaptive rather than maladaptive variants of these domains of personality functioning within the NEO-PI-R. This hypothesis was tested by experimentally altering NEO-PI-R items to reverse their implications for maladaptiveness. The predicted correlations of the FFM were confirmed with the experimentally altered items in a sample of 86 adult psychiatric outpatients.
