Internet Addiction and Gaming Disorder Assessment

The survey at both sites included the latest refinement of the Internet Addiction Test (IAT-10) [26 (link)], a shortened ten-item version of Young's Internet Addiction test [35 (link)] with improved psychometric properties through IRT. The Internet Gaming Disorder Test (IGDT) [23 (link)], an established 10-item instrument measuring online gaming that operationalizes the nine DSM-5 criteria for Internet gaming disorder [36 ], was also included in the survey. The South Africa survey additionally included the short (5-item) Compulsive Internet Use scale (CIUS) [37 (link)], an established screening instrument of PUI with very similar sensitivity and specificity to the original full CIUS scale [24 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
