Comparative Study of the Characteristics of the P300 Wave and the Event-Related θ Rhythm in Schizophrenia and Personality Disorders

Summary. Objective: A comparative study of the personality structure from the perspective the Five-factor personality model (“Big Five”) in mentally healthy and in people with personality disorders depending on the leading radical determined by the clinical method.Materials and methods: a comparative study of personality structures in the mentally healthy (13 people) and in individuals with personality disorders (47 people) was carried out. To assess the personality structure, the NEO-Five Factor Inventory questionnaire was used. Persons with personality disorders were divided into groups in accordance with the leading radical: 24 — with emotionally unstable; 13 — with a histrionic; 6 — with schizoid; 4 — with paranoid radicals.Results: There were no differences in the values of the domains of the Five-Factor personality model between a group of individuals with personality disorders and the norm. The features of domain indicators of the Five-factor personality model were revealed in individuals with personality disorder depending on theradical.Conclusion: The NEO-Five Factor Inventory questionnaire, like most other tools from the perspective of the Five-Factor Model, is not suitable for assessing a person in terms of assigning it to variants of a mental disorder. When comparing the categorical and dimensional approaches to assessing the structure of personality disorders, it was found that the obligate personality traits identified using the categorical approach are fully reflected in the «Big Five» in individuals with a leading schizoid radical. The relations of obligate personal traits with the domains of the Five-factor model of personality in individuals with other (paranoid, histrionic,and emotionally unstable) radicals are less clear.

Patient Groups

SummaryWe investigated the overall prevalence and the differential comorbidity of Diagnostic and Statistical Manual (DSM)-III-R personality disorders in 166 remitted or recovered patients with schizophrenic (n = 102) or unipolar mood disorder (n = 64). Over 60% of both patient groups met the DSM-III-R criteria of at least one DSM-III-R personality disorder as assessed by means of the Structured Clinical Interview for DSM-III-R (SCID-II-R), receiving on average 3.1 personality diagnoses. Neither DSM-III-R categories of personality disorders, nor scores on its three clusters A, B and C, nor total score on SCID-II-R differed significantly across the two groups. In conclusion, DSM-III-R personality disorders, although highly prevalent in schizophrenic and unipolar mood disorders, lack any specificity with respect to these categories of mental disorders.
