The treatment of individuals suffering of psychiatric disorders is often complicated by comorbid personality disorders in clinical practice. It is important to understand the whole complexity of disturbances of a patient from the beginning of her/his treatment in order to develop individually adequate goals. The diagnostic of personality disorders has been widely discussed during the last decade. It is still a challenge in everyday clinical work. The diagnostic criteria of the ICD-10 and the DSM-IV are not always identically. The personality disorders criteria are still in development and, as well known out of the clinical practice, it is often complicated to recognize comprehensively all personality disturbances of a patient. The TCI is a widely used personality test. It was developed to measure four temperament dimensions, and three character dimensions described in Cloninger's unified biosocial theory of personality. The character dimensions self-directedness and cooperativeness are sensitive to personality disturbances. Individuals with limitations in these character dimensions are at risk for personality disturbances. About 800 healthy subjects from Sweden and from Germany and 200 consecutive psychiatric inpatients from these countries are investigated by means of the TCI. Groups were built dependent upon the expression of the scores in the temperament dimensions. The results support the idea that patients, who scored low in self-directedness and in cooperativeness combined with extreme temperament scores, are more likely to suffer from a personality disorder. The TCI established as a useful tool in the diagnostic process of personality disturbances.
