摘要

The present study validated the Gaming Disorder Test (GDT) and the Gaming Disorder Scale for Adolescents (GADIS-A) among Hong Kong university students. Using convenience sampling, 790 participants (63% females, age = 22.5 years [± 4.4]) completed an online survey including the GDT, GADIS-A, Internet Gaming Disorder Scale-Short Form (IGDS9-SF), Depression Anxiety Stress Scale-21 (DASS-21), and Tendency to Avoid Physical Activity and Sport Scale (TAPAS). The expected factor structures of the GDT (one-factor) and GADIS-A (two-factor) were confirmed with strong factor loadings from 0.70 to 0.86. Moderate to high significant correlations between both scales and the IGDS9-SF, DASS-21, and TAPAS showed appropriate concurrent/convergent/divergent validity (0.20 < r < 0.83). Both scales were internally consistent (0.88 < α / ω < 0.93). Both scales were invariant across gender, severity of problem, and educational major. Both the GDT and GADIS-A are valid and reliable tools to assess gaming disorder among young university students in Hong Kong.
