POSSIBILITIES OF USING THE SANS METHOD FOR ASSESSING THE DYNAMICS OF ANHEDONIA AND ASOCIALITY IN PATIENTS WITH NEGATIVE SYMPTOMS IN SCHIZOPHRENIA

Authors

Abstract

To study the dynamics of anhedonia and asociality in patients with negative symptoms in schizophrenia, clinical-psychopathological, psychometric (SANS scale) and statistical research methods were used. 252 patients with negative symptoms of schizophrenia took part in the study: 83 patients with a first psychotic episode, 88 patients with schizophrenia in a state of exacerbation, and 81 patients with schizophrenia in a state of remission. It was established that the most affected patients with the first psychotic episode were a decrease in sexual interests, the ability to feel intimacy and closeness, and subjective awareness of anhedonia and asociality. Anhedonia and sociability indicators increased in patients with schizophrenia during exacerbations, which was manifested in the severity of a low ability to feel intimacy and closeness, a decrease in the desire to communicate with relatives and friends, a decrease in sexual interests and activity in free time. In schizophrenic patients in a state of remission, the most decreased indicators were autism, sexual interests, and activity.
