Introduction: Despite many patients with schizophrenia being able to achieve good functional outcomes, the number of patients with poor functional outcome estimates at over 25 percent. One of the wider constructs, reflecting functional outcomes in schizophrenia, is real-life functioning, whose key domains include ability to live relatively autonomously, productive activity and social interaction. Negative symptoms are seen among independent predictors of real-life functioning. As most researchers agree that schizophrenia is a disease with gender differences in terms of both clinical and functional outcomes, the goal of our observational study was to examine real-life functioning of women with schizophrenia, living in residential care facilities, and study the relationship between daily functioning and negative symptoms., Methods: Using the Standardized Protocol of Clinical Interview and observation for 1 or more weeks, we examined 46 females with schizophrenia, living in psychiatric residential facilities and compared them with 54 males with schizophrenia, living in the same facilities. In a pilot study 21 subjects with schizophrenia (13 females and 8 males), were evaluated by the Russian version of the Brief Negative Symptom Scale (BNSS)., Results: To the results, more females with schizophrenia, compared to males with schizophrenia, remained active and took initiative in their physical care, vocational activities, involvement in cultural events, and maintained friendly relationships with other inmates. We have identified a group of inmates, in which females prevailed, with less pronounced negative symptoms and a higher level of social functioning, who did not need residential social care in the institutions., Discussion: Limitations of residential social care in the institutions for psychiatric patients are discussed., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Rusakovskaya, Kharitonova, Movina and Papsuev.)

Background: Negative symptoms are usually evaluated with scales based on observer ratings and up to now self-assessments have been overlooked. The aim of this paper was to validate the Self-evaluation of Negative Symptoms (SNS) in a large European sample coming from 12 countries. We wanted to demonstrate: (1) good convergent and divergent validities; (2) relationships between SNS scores and patients' functional outcome; (3) the capacity of the SNS compared to the Brief Negative Symptom Scale (BNSS) to detect negative symptoms; and (4) a five-domain construct in relation to the 5 consensus domains (social withdrawal, anhedonia, alogia, avolition, blunted affect) as the best latent structure of SNS., Methods: Two hundred forty-five subjects with a DSM-IV diagnosis of schizophrenia completed the SNS, the Positive and Negative Syndrome Scale (PANSS), the BNSS, the Calgary Depression Scale for Schizophrenia (CDSS), and the Personal and Social Performance (PSP) scale. Spearman's Rho correlations, confirmatory factor analysis investigating 4 models of the latent structure of SNS and stepwise multiple regression were performed., Results: Significant positive correlations were observed between the total score of the SNS and the total scores of the PANSS negative subscale ( r = 0.37; P < 0.0001) and the BNSS ( r = 0.43; p < 0.0001). SNS scores did not correlate with the level of insight, parkinsonism, or the total score of the PANSS positive subscale. A positive correlation was found between SNS and CDSS ( r = 0.35; p < 0.0001). Among the 5 SNS subscores, only avolition subscores entered the regression equation explaining a lower functional outcome. The 1-factor and 2-factor models provided poor fit, while the 5-factor model and the hierarchical model provided the best fit, with a small advantage of the 5-factor model. The frequency of each negative dimension was systematically higher using the BNSS and the SNS vs. the PANSS and was higher for alogia and avolition using SNS vs. BNSS., Conclusion: In a large European multicentric sample, this study demonstrated that the SNS has: (1) good psychometric properties with good convergent and divergent validities; (2) a five-factor latent structure; (3) an association with patients' functional outcome; and (4) the capacity to identify subjects with negative symptoms that is close to the BNSS and superior to the PANSS negative subscale., Competing Interests: SD has been an expert and consultant or participated in educational conferences for the following industrial laboratories or companies: Gedeon Richter, Lundbeck Otsuka, Roche, Takeda, Fabre, Janssen, ONO Pharma, and Verasci.
