“…Several assessment tools and screening tests based on the diagnostic criteria of IGD were developed following the publication of DSM-5 ( Jo et al., 2018 ; Király et al., 2017 ; Lemmens, Valkenburg, & Gentile, 2015 ; Pearcy, Roberts, & McEvoy, 2016 ; Pontes & Griffiths, 2015 ; Pontes, Király, Demetrovics, & Griffiths, 2014 ; van Rooij, Schoenmakers, & van de Mheen, 2017 ). Some of these have been extensively validated and translated into other languages ( Chen, Su, Dang, & Wu, 2021 ; Király et al., 2017 ; Pontes & Griffiths, 2015 ). One such test, the Ten-Item Internet Gaming Disorder Test (IGDT-10) has been translated into multiple languages, including Japanese ( King et al., 2020 ).…”
