The Values in Action Inventory of Strengths (VIA-IS) has become the widely used instrument to measure 24 character strengths. However, the lack of adapted Russian-language versions limits the application, particularly that its factor structure remains a subject of ongoing debate. The aim of the present study was to adapt a Russian-language version of the Values in Action Inventory of Strengths – Virtues 6 (VIA-IS-V6), developed to assess character strengths. The study used an evaluation of psychometric properties, including factor structure, reliability and validity among 523 Kazakhstani financial professionals working in public and private organizations. The results revealed high level of internal consistency reliability for the six virtues and 24 character strengths, with a Cronbach’s α of =.94 and =.90, respectively. The assessment of convergent validity showed that the VIA-IS-V6 significantly and positively correlated with mental well-being and significantly and negatively correlated with job stress, work pressure, lack of organizational support, and perceived stress. Exploratory factor analysis revealed a four-factor structure explaining 53% of the total variance. Strong factor loadings were observed for items such as judgment, bravery, honesty, zest, love, fairness, forgiveness, humility, prudence, self-regulation, appreciation of beauty and excellence, gratitude and humor. Confirmatory factor analysis confirmed the four-factor structure of the instrument. The findings of the current study confirm that the adaptation of the Russian-language version of the Values in Action Inventory of Strengths – Virtues 6 (VIA-IS-V6) showed high reliability, validity and good psychometric characteristics. The instrument might be recommended for assessing individual character strengths in scientific research and applied psychology.
