This study examines the psychometric properties of the Russian adult version of the Structure of Temperament Questionnaire (STQ-77Ru) within a diverse community sample. Employing both network psychometrics and Item Response Theory (IRT), we analyzed data from 3,442 Russian participants, aged between 18 and 81 years (M = 38, SD = 11). Network psychometrics were used to explore the complex interdependencies among temperament traits, while IRT provided detailed insights into the difficulty and discrimination of individual test items. Measurement equivalence tests supported high consistency in factor loadings and intercepts across different sexes and educational levels, enhancing the tool’s applicability across demographics. This study further evaluated the ability of STQ-77Ru to distinguish between demographic groups, revealing substantial variations in temperament traits between males and females and across different levels of educational attainment. These findings validate the questionnaire’s effectiveness in diverse settings and, with some reservations, underscore the potential of STQ-77Ru for delivering precise and reliable psychological assessments of temperament traits within the Russian community.
