The aim: to determine the features of the clinical-psychopathological structure and severity of negative and positive symptoms in patients with schizophrenia to improve diagnosis and treatment of schizophrenia.
 Materials and methods. 252 patients with negative symptoms (NS) in schizophrenia and 79 patients with positive symptoms (PS) in schizophrenia were examined. The research used a comprehensive approach, which consisted in the use of clinical-psychopathological, psychometric (PANSS scale) and statistical research methods.
 Results. Manifestations of positive symptoms in patients with NS in schizophrenia were mainly delineated by delusions of a minimal and weak level; minimal manifestations of delirium, unusual behavior and thought disorders; the predominance of patients with no disorders, minimal disorders and a weak level of disorders of hallucinatory behavior, excitement, ideas of grandeur, suspiciousness, and hostility. Manifestations of negative symptoms in patients with NS in schizophrenia were characterized by a predominance of medium and severe levels of blunted affect; moderate and average levels of emotional alienation; violation of abstract thinking of a weak and moderate level; average level of impaired fluency and spontaneity of speech; moderate communication impairment; passive-apathetic social detachment of the average level.
 Among patients with PS in schizophrenia, the manifestations of positive symptoms were mainly delineated by delusions of medium and strong levels of severity; moderate and pronounced manifestations of delirium; a moderate level of severity of thinking disorders and unusual behavior; predominance of moderate, medium and strong levels of expression of hallucinatory behavior, excitement, ideas of grandeur, suspicion and hostility. Manifestations of negative symptoms in patients with PS in schizophrenia were characterized by a predominance of a minimal level of expression of dulled affect, social exclusion and impaired fluency and spontaneity of speech; minimal and weak levels of emotional alienation; average level of communication disorders and abstract thinking.
 Conclusions. Features of the clinical-psychopathological structure and severity of negative and positive symptoms in patients with schizophrenia were established. The obtained data can serve as diagnostic criteria for conducting differential diagnosis and choosing treatment strategies for patients with schizophrenia.
