Abstract

A total of 166 online video game players demonstrated a good validity for the French version of the IGD-20 scale.

The IGD-20 scale is designed to assess problematic use of online video games, based on a six-component model of addiction.
Participants reported playing an average of 21.9 hours of online video games per week.
Confirmatory factor analysis indicated a six-factor structure for the IGD-20, including salience, mood modification, tolerance, withdrawal symptoms, conflict, and relapse.
The validation metrics showed a root mean square error of approximation (RMSEA) of 0.063 and comparative fit indices (CFI = 0.912, TLI = 0.909).
The validated scale may provide useful insights for therapists and individuals experiencing Internet Gaming Disorder.

BACKGROUND: The study aims to validate an online video game problematic use (Internet Gaming Disorder or IGD) scale in French language: the IGD-20. IGD-20 has been elaborated considering the discussion about the etiology of the IGD, which was included in the section III of the DSM-5. The IGD-20 is composed of 20 items split in six components based on the six components model of addiction from Griffiths.

METHODS: A total of 166 online video game players were recruited on specialized forums, playing 21.9 hours per week. The French version of the IGD-20 was validated through a confirmatory factor analysis via structural equation modeling (SEM).

RESULT: The French version of the IGD-20 showed a good validity and a six-factor structure (salience, mood modification, tolerance, withdrawal symptoms, conflict and relapse) (RMSEA = 0.063 [0.049; 0,077], CFI = 0.912, TLI = 0.909).

CONCLUSION: The validation of a French scale such as the IGD-20 shows some interest for the French-speaking population, including therapists who could use this scale to investigate the IGD-20 more precisely and for people with IGD-20 who could benefit from a more refined support.
