Assessment of Gaming Disorder with the IGDS9-SF

Discussing the latest evidence behind the IGDS9-SF

Hello everyone,

I was pleased to see that a recent study published by Anthony and colleagues (2022) in the journal Clinical Psychology: Science and Practice provided further insights on the psychometric properties and usability of the Internet Disorder Scale-Short Form (IDS9-SF), which was the first brief standardized assessment tool for ‘Internet Gaming Disorder’ as defined in the DSM-5.

The IGDS9-SF was published in December 2014 in the journal Computers in Human Behavior, and after nearly a decade since its publication and numerous studies supporting its use worldwide, a new study provided further support to previous research.

Upon evaluating a set of 22 psychometric tests measuring ‘Internet Gaming Disorder’, Anthony and colleagues (2022) reported that:

Among all reviewed measures, the IGDS9-SF has been evaluated by the highest number of empirical studies (n = 26). In contrast, all other measures were evaluated by only a few studies (ns = 1–5).

They further noted that:

Based on the COSMIN guideline, the IGDS9-SF demonstrates sound structural validity, internal consistency reliability, construct validity (convergent and divergent validities), test-retest reliability, and measurement invariance among gender, age groups (including three studies evaluating measurement invariance between adolescent and adult samples), and regions with moderate- to high methodological quality.
