Background: This scientific article is significant due to the lack of Russian-language psychometric scales that can objectively assess the parameters of personal recovery within the broader concept of 'recovery'. In the context of growing interest in the rehabilitation of patients with mental disorders and the need to create effective resource systems to help people who have experienced the first psychotic episode, the validation of the Russian version of the Recovery Assessment Scale – Domains and Stages (RAS-DS) opens up new horizons for clinical practice and scientific research. The aim of the study:To adapt and validate the Russian version of the recovery assessment Scale – Domains and stages Recovery Assessment Scale – Domains and Stages by Nicola Hancock (RAS-DS). Materials and methods: The study involved 129 patients with a first psychotic episode, aged 16–50 years (mean age 31 years, SD 7.9 years), who underwent a comprehensive rehabilitation programme lasting up to two years from the start of hospitalisation. The majority of participants were men (79.1%, n = 102), and the length of hospitalisation ranged from 24 to 88 days (mean = 42 days, SD = 13.8). PANS, PSP, SFS, BS, GIF, RUS-DS were used as methods for determining the degree of recovery of patients. The α-Kronbach coefficient was used to determine the internal reliability of the structure of the psychometric scale. To assess the structure of the questionnaire, factor analysis using the principal component method was applied. The Student's t-test was used to compare quantitative indicators of different groups of psychometric data with a normal distribution of variables. Correlation analysis was used to describe the relationship between the scales. Results: The α-Kronbach coefficients for all scales and the overall RAS-DS index exceeded the value of 0.90, defined as excellent for the internal reliability of the diagnostic tool. This model demonstrated excellent data consistency, taking into account the use in calculations of the RMS approximation error RMSEA (RMSEA=0.0474, p<0.001); comparative compliance index CFI (CFI=0.969); Tucker–Lewis index TLI (TLI=0.945). During the analysis of convergent validity, a high direct correlation was revealed with the psychometric scales GAF (r=0.93, p<0.001), SFS (r=0.91, p<0.001), PSP (r=0.84, p<0.001) and inverse correlation with the PANSS questionnaires (r=-0.71, p<0.001) and BHS (r=-0.83, p<0.001), which confirms the validity and reliability of the investigated method for assessing complex recovery. Conclusion: The Russian-language version of the RAS-DS scale was successfully adapted on a sample of patients after the first psychotic episode who underwent a comprehensive rehabilitation program and can be recommended as a tool and screening for the recovery of patients after PPE in Russian-speaking respondents
