Abstract

Background. The study of negative symptoms in schizophrenia requires, in addition to the clinical and psycho-pathological method, the use of other objective test diagnostic methods that would allow a quantitative assessment of the severity of negative symptoms. One of the methods for objective assessment of negative disorders in schizophrenia, allowing a quantitative assessment of their severity, is the psychometric method, among the advantages of which are the simplicity and compactness of the implementation, the presence of standardized rating scales that make it possible to reasonably assess the severity of symptoms, as well as compare the results of different patients with each other. Objective of the study: to present an overview of psychometric tools for assessing negative symptoms in schizophrenia. Materials and Methods. The search of scientific literature was conducted in the Google Scholar and PubMed scientific databases using the following keywords and phrases: schizophrenia, negative symptoms, test, scale, questionnaire, psychometric. Studies are highlighted that consider the psychometric properties of the original scales assessing negative disorders in schizophrenia. The results of studies on this topic are mainly published in English-language reviews and meta-analyses. Results and Discussion. The historical path of development of the psychometric method for assessing negative disorders in schizophrenia is followed, comparative characteristics of test methods are presented, and sources are indicated that present facts of Russian-language adaptation of specific scales, if any.

 

Keywords: schizophrenia, negative symptoms, diagnostics, psychometric approach, standardized tests, questionnaires.
