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