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. . [ABSTRACT FROM AUTHOR]

The Assessment of Criteria for Specific Internet-use Disorder (ACSID-11) is a psychometric instrument assessing different types of problematic internet use. The aim of the present study was to assess the psychometric properties of the traditional Chinese version and evaluate whether the traditional Chinese version showed similar and robust psychometric evidence to that of original ACSID-11 using a German sample. The present study was longitudinal and comprised 1257 university students in the first study and 409 university students in the follow-up study. Cronbach’s α and McDonald’s ω were used for testing internal consistency of the ACSID-11. A confirmatory factor analysis (CFA) was conducted to examine construct validity. Multi-group CFA was performed to assess the invariance of the factor structure across region and sex. Moreover, Pearson correlations were conducted to examine the test–retest reliability and concurrent validity of ACSID-11. The results suggested satisfactory levels of test–retest reliability, internal consistency, and validity of the ACSID-11. The four-factor structure of the ACSID-11 was replicated and confirmed in both Taiwan and Hong Kong samples. The study findings demonstrated that the traditional Chinese version of the ACSID-11 is reliable and valid for assessing and distinguishing specific internet-use disorders and is applicable across regions and sexes among emerging adults in Taiwan and Hong Kong.

As research on gaming disorder (GD) is growing globally, the need for a valid and reliable instrument to assess GD has become crucial. Therefore, the present cross-sectional study translated and evaluated the psychometric properties of Gaming Disorder Test (GDT) and Gaming Disorder Scale for Young Adults (GADIS-YA) into Malay language versions. The sample comprised 624 university students (females = 75.6%; mean age = 22.27 years) recruited via an online survey from May to August 2022, using a convenience sampling method. Participants completed both GDT and GADIS-YA scales and other relevant measures including Bergen Social Media Addiction Scale (BSMAS), Internet Gaming Disorder Scale-Short Form (IGDS9-SF), and time spent on social media and gaming. Results showed that both instruments reported satisfactory internal consistency, and confirmatory factor analysis supported the one-factor structure for GDT and two-factor structure for GADIS-YA. Both scales were strongly correlated with each other and with the IGDS9-SF, BSMAS, and time spent on social media and gaming, supporting concurrent validity. Measurement invariance of both scales was confirmed across gender and gaming time. These findings suggest that the Malay versions of GDT and GADIS-YA are reliable and valid measures of problematic gaming among Malaysian university students. [ABSTRACT FROM AUTHOR]
