Abstract
Assessing functionality in schizophrenia from a biopsychosocial perspective is essential to generate treatments that respond to the needs of the individual in his/her context. This research aims to assess the prevalence of functioning problems and their association with socio-demographic and clinical variables in a sample of Russian individuals with schizophrenia, using the International Classification of Functioning, Disability, and Health as a framework. An empirical cross-sectional study assessed the functioning of 40 individuals with schizophrenia using the International Classification of Functioning, Disability, and Health Core Set for schizophrenia. For the Body functions component, the highest prevalence of problems was found in b144 Memory functions (75%) and b140 Attention functions (70%). In the Activities and participation component, the greatest limitations were in d770 Intimate relationships (79.3%) and d240 Handling stress and other psychological demands (82.5%). In the Environmental factors, the most frequent problems were in e110 Products or substances for personal consumption (25%) and e460 Societal attitudes (22.5%); when scored as facilitators, the highest rated categories were e125 Products and technology for communication (100%) and e165 Assets (100%). These results may guide the design of specific treatments for these individuals and serve as a starting point for further studies in similar contexts and in other regions in Russia.
