<p>This study aimed to evaluate the psychometric properties of the short-form version of the Game Addiction Scale (GAS) on Argentinian gamers. The sample was composed by 882 gamers (Men= 53.2%; Woman= 46.8%), with age ranging from 13 to 59 years (M= 22.59; SD= .200). The analysis of the reliability and validity was measure with the McDonald’s omega (ω) and the Confirmatory Factor Analysis, both performed on the unidimensional model proposed by Lemmens, Valkenburg &amp; Peter (2009) and the bidimensional model proposed by Brunborg et al. (2013). The results indicated that the bidimensional model is more adequate for the Argentinian population (CFI = .994; GFI= .998; SRMR= .025 y RMSEA= .044; ω= .838). Furthermore, the study analyzed the criteria classification proposed in both models. Between them, the model of Brunborg et al. (2013) might be more appropriate for classification because it takes into consideration different typologies (addicted gamer, problematic gamer, engaged gamer, or non-engaged gamer). However, it is important to develop more research (empirical and clinical) for the confirmation or modification of this classification.</p>
