Abstract

Objectives: The aim of this study was to develop and examine the psychometric properties of the IGDS9-SF in a sample of Brazilian gamers and to find the best cut-off point for this instrument using a normative and clinically diagnosed sample of gamers. Methods: A total of 610 participants were recruited to the present study. Construct validity was assessed through Exploratory and Confirmatory Factor Analysis (EFA, CFA). Criterion-related validity was established through the associations with Game Addiction Scale (GAS) and weekly gameplay. Reliability analysis was performed using the Cronbach’s alpha (α) as the indicator of internal consistency. A cut-off point was estimated using the Receiver Operating Characteristics Curve (ROC curve) where the results of a clinical assessment was used as the gold standard. Results: EFA and CFA findings confirmed the single-factor structure of the IGDS9-SF. Positive correlations indicated adequate criterion-related validity, and the scale was shown to be reliable (α=0.82). Finally, the optimal cut-off point for risky gaming was found to be >16 points and for diagnosis to be >21 points. Conclusions: This study provides validity and reliability evidence for the use of the Brazilian version of the IGDS9-SF in the assessment of Internet Gaming Disorder, further supporting its usefulness as a robust psychometric tool that can be employed in clinical and research settings in Brazil.
