Introduction Despite numerous studies of the mental health and well-being of the population depending on various factors, insufficient attention is paid to the research of the relationship between well-being and mono- and multilingual regional specifics in multilingual and multicultural Russia. Objectives This study aims to identify a possible relationship between mental well-being in some regions of the Russian Federation and monolingualism and multilingualism inherent in these regions. Methods The study involved 966 participants (29.5% men and 70.5% women) aged 11 to 80 years (M=24.8; SD=12.19) from six regions of the Russian Federation: Crimea, Adygea, Bashkortostan, Sakha, Tatarstan and Kabardino-Balkarian region. The mental well-being of participants was assessed using the Warwick-Edinburgh Mental Well-being Scale (Tennant et al., 2006; Tennant et al., 2007). Results The measures of mental well-being were compared among residents from the regions as following categories: native Russian language speakers in monolingual regions (144 participants); native Russian language speakers in multilingual regions (193 participants); native national language speakers in multilingual regions (325 participants); native Russian and national languages speakers in multilingual regions (304 participants). Using one-way analysis of variance (ANOVA), it was found that there were no significant differences in the assessments of mental well-being (F = 0.852; p = 0.521) among residents from the above categories. Conclusions Residents who are native speakers in Russian and national languages and are living in Russia’s regions with monolinguism and multilinguism demonstrate no difference in mental well-being measures. The reported study was funded by the RFBR, project number 17-29-09167. Disclosure No significant relationships.

Introduction Important role of sociocultural mediation of human health is reflected in the regional specificity of subjective evaluation of factors determining human health. Objectives The research is focused on the opinion of respondents from different regions of Russia about the importance of various factors that determine health and subjective well-being. Methods 210 men and 403 women aged 14 to 76 years (M=26.9; SD=13.7) from six regions of the Russia (Moscow, St. Petersburg, Udmurtia, Sakha, Sverdlovsk and Kemerovo) participated in the study. Respondents were asked to rank six factors (genetics, healthy lifestyle, good ecology, regular medical examination, absence of stress, financial well-being) in terms of their impact on health (1 is the most important, 6 is the least important). Results It was revealed significant differences among respondents from different regions of the Russia in evaluation of importance of health factors such as “genetics” (F=3.317; p=0.003) and “good ecology” (F=5.008; p<0.001). Respondents from the Sverdlovsk consider “genetics” significantly more important than participants from the Sakha (MD=-0.706; p=0.019) and Kemerovo (MD=-0.859; p=0.015). Respondents from St. Petersburg consider the ‘good ecology’ significantly less important than participants from Moscow (MD=0.791; p=0.046), Udmurtia (MD=0.867; p=0.035), Sakha (MD=1.168; p<0.001), and Kemerovo (MD=1.286; p<0.001). Conclusions Regional specificity was found in the subjective evaluation of the importance of factors that determine health and subjective well-being. The reported study was funded by the RFBR, project number 17-29-02506. Disclosure No significant relationships.
