Abstract

The purpose of this study is to investigate whether the factors from the Five-Factor Model of Personality can be applied to a categorical model of personality disorders. Three hundred ninety subjects, who were over 19 years of age, participated in collecting the data. The five factors (neuroticism, extroversions, openness to experience, agreeableness, conscientiousness) of personality showed significantly correlations with the scores of the ten DSM-Ⅳpersonality disorders. On the results of multiple regression analysis, the five factors of personality significantly predicted the DSM-IV personality disorders. The Paranoid, Schizotypal, Borderline, Avoidant, and Dependant PDs were positively predicted by ‘neuroticism’. The Paranoid, Schizoid, Avoidant, and Obsessive-Compulsive PDs were negatively predicted and the Borderline PD was positively predicted by ‘extroversion’. The Schizotypal, Borderline, and Narcissistic PDs were positively predicted by ‘openness to experience’. The Paranoid, Schizotypal, Antisocial, Borderline, Histrionic, and Narcissistic PDs were negatively predicted by ‘agreeableness’. The Paranoid and Obsessive-Compulsive PDs were positively predicted and the Histrionic and Narcissistic PDs were negatively predicted by ‘conscientiousness’. These results suggest that personality disorders can be represented by the Five-Factor Model of Personality.
