Researching Psychometric Properties of Igd-20 Scale in Bosnia-Herzegovina Speech Area

Summary/Abstract: The aim of this study was to examine the psychometric properties of the IGD-20 scale, developed by Pontes et al. (2014) for the assessment of Internet gaming disorder, which was translated in this study using the back-translation method and administered to a sample of gamers and eSports players in Bosnia and Herzegovina. The sample consisted of 278 participants (82% gamers and 18% eSports players), predominantly male, with an average age of 27 years. Item analysis demonstrated satisfactory discriminative power and high item-total correlations for all items. The overall reliability of the IGD- 20 scale was exceptionally high (α = 0.965). Exploratory factor analysis initially suggested a three-factor solution; however, this solution was neither interpretable nor consistent with the original structure of the instrument. A unidimensional solution, which has also been supported in recent research, proved to be the most interpretable and accounted for over 61% of the variance. In conclusion, the IGD-20 scale demonstrates excellent psychometric properties in terms of reliability and discriminative validity, but its factor structure requires further investigation on larger and more heterogeneous samples, as well as examination of shorter versions of the instrument. The results of this study provide a foundation for further validation of the IGD-20 scale in Bosnia and Herzegovina and beyond.
