In 2004 Peterson and Seligman presented their concept of virtues and 24 character strengths which are widely-valued positive characteristics considered to be important for achieving a good, happy life (Peterson, Seligman, 2004). For their measurement Peterson and Seligman (2004) developed Values in Action – Inventory of Strengths (VIA-IS). As a part of his International Personality Item Pool project (ipip.ori.org), Goldberg developed his own measurement of Peterson and Seligman’s character strengths, which differs from VIA-IS for example in its open access form. Research on Polish version of the International Personality Item Pool – Values in Action questionnaire (IPIP-VIA) was conducted on a sample of N = 908 adults. It proved satisfactory psychometric properties of the tool. High or satisfactory reliability for all the scales measuring character strengths was achieved. Validity of the tool was tested by comparing sex differences obtained in research with a Polish version of the IPIP-VIA and the results of studies conducted in the UK with the VIA-IS questionnaire.

This study aimed to verify the psychometric properties of the Polish version of the Grit-S questionnaire. Grit is understood here as the perseverance and passion for long-term goals, and it encompasses two dimensions: Consistency of Interest and Perseverance of Effort. The sample comprised N = 270 participants aged 18–34 (Mage = 20.79). We performed confirmatory factor analyses to verify the dimensional structure of grit, multi-group confirmatory factor analysis to compare the structure across gender, and correlation analysis to examine external validity (exploring the correlations between grit, procrastination, and well-being). Findings showed satisfactory parameters for Grit-S including: reliability, structural and external validity, and measurement invariance across gender groups. The results support the possibility of using the Grit-S questionnaire in research exploring the predictors of success.
