Abstract

The prevalence rate of (IGD) among eighth graders in Slovenia is approximately 2.5%.

The 9-item Internet Gaming Disorder Scale - Short-Form () demonstrated strong validity and reliability in assessing IGD.
A unidimensional structure of the IGDS9-SF was confirmed through factor analysis, indicating a cohesive measurement of IGD.
Significant associations were observed between IGD and various psychosocial and game-related factors, supporting the instrument's concurrent and criterion validity.
The internal consistency of the Slovenian version of IGDS9-SF was rated as excellent across different assessment levels.
Among identified gamers, the prevalence of IGD was higher at around 3.1%.

Background and aims Since the inclusion of (IGD) in the latest (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a tentative disorder, a few psychometric screening instruments have been developed to assess IGD, including the 9-item Internet Gaming Disorder Scale - Short-Form () - a short, valid, and reliable instrument. Methods Due to the lack of research on IGD in Slovenia, this study aimed to examine the psychometric properties of the IGDS9-SF in addition to investigating the prevalence rates of IGD in a nationally representative sample of eighth graders from Slovenia (N = 1,071). Results The IGDS9-SF underwent rigorous psychometric scrutiny in terms of validity and reliability. Construct validation was investigated with confirmatory factor analysis to examine the factorial structure of the IGDS9-SF and a unidimensional structure appeared to fit the data well. Concurrent and criterion validation were also investigated by examining the association between IGD and relevant psychosocial and game-related measures, which warranted these forms of validity. In terms of reliability, the Slovenian version IGDS9-SF obtained excellent results regarding its internal consistency at different levels, and the test appears to be a valid and reliable instrument to assess IGD among Slovenian youth. Finally, the prevalence rates of IGD were found to be around 2.5% in the whole sample and 3.1% among gamers. Discussion and conclusion Taken together, these results illustrate the suitability of the IGDS9-SF and warrants further research on IGD in Slovenia.
