Psychometric Properties of the Thai Gaming Disorder Test (GDT) and Thai Gaming Disorder Scale for Adolescents (GADIS-A)

ABSTRACT

The present study examined psychometric properties of the Gaming Disorder Test (GDT) and Gaming Disorder Scale for Adolescents (GADIS-A), among Thai university students. A convenience sample of university students (n = 612) completed an online survey. . A one-factor structure for GDT, and a two-factor structure for GADIS-A were confirmed . Omega coefficients for both scales were acceptable. . There were positive significant associations between the assessed scales and other related measures indicating convergent validity. Appropriate fit indices were found (across gender and daily time spent gaming supporting measurement invariance. The GDT and GADIS-A are appropriate instruments to assess gaming disorders among Thai university students. .
