In recent years, research on the comorbidity of personality disorders and other clinical conditions has increased. Nevertheless, it is quite surprising that very little research has been done in terms of personality and its disorders in patients with schizophrenia. Most of the studies related to the binomial construct of personality disorders and schizophrenia are limited to the study of premorbid personality, which emphasizes the importance of the interaction between trait-personality disorder-schizophrenia symptoms. The study of personality in patients with schizophrenia suggests several issues that must be considered, including the trait-state interactions and the role of personality in the course of schizophrenia. The conceptual definition of trait emerges from the dimensional classification of models of personality. In this way, knowing that some personality features are present in all individuals, we can assume that their deviation in a quantitative level results in abnormal personality features that constitute personality disorders or even can be expressed as a specific expression of some schizophrenia symptoms. Although there is growing evidence in the knowledge of schizophrenia, there are very few models that include the scientific neurobio-logical evidence of the disease and personality features. An inclusive model may promote our understanding of the relationship between schizophrenia symptoms and the personality features of the patient who suffers the disease. So far, we are still far from reaching scientific consensus to be unanimously shared by all researchers with respect to both issues. Nevertheless, the importance of personality in schizophrenia is undeniable, so future longitudinal that assess personality characteristics since illness onset should be warranted. These studies may be extremely useful to determine personality stability during the course of the illness and may help to determine the prognosis and treatment implications of personality in schizophrenia.
