Game Behavior Scale-Electronic (GBS-E): elaboration and psychometric evidence.

Despite the growing engagement in electronic games globally and the need to measure behavior in this context, there are few instruments for this purpose. The present study aimed to develop and validate the Game Behavior Scale-Electronic (GBS-E) in Brazil. In Study 1 (N=409), exploratory factor analysis supported the adequacy of a two-factor solution (individual and collective behavior). In Study 2 (N=373), we used confirmatory factor analysis, item response theory (to evaluate the discrimination and difficulty levels), and graphical factor analysis to test the above version of the scale and propose a short form of the GBS-E. The results suggest that both forms (full form, 31 items and short form, 10 items) of the GBS-E demonstrate psychometric evidence (factorial validity and internal consistency) for the adequacy of the measure to evaluate individual and collective behavior in electronic games.
