Scoping review of withdrawal's role in contemporary gaming disorder research: Conceptualizations and operationalizations.

The global gaming community now exceeds 3 billion players, prompting increased attention from social and medical sciences regarding gaming-related disorders. Internet Gaming Disorder (IGD) was incorporated into DSM-5 in 2013, and Gaming Disorder (GD) found its place in ICD-11 in 2019. A contentious criterion in IGD, not present in GD, revolves around withdrawal symptoms. This paper offers a theoretical foundation on gaming withdrawal symptoms in gaming-related disorders and conducts a scoping review of withdrawal operationalization and conceptualization in 40 selected studies, following PRISMA-ScR guidelines. Most studies employed a correlation framework, relying on convenience samples and self-assessment questionnaires. A smaller portion focused on clinical samples and case studies. Withdrawal was predominantly conceptualized in terms of affective components, with less emphasis on behavioural, cognitive, physical, or neurological aspects. The prevailing terminology for gaming-related disorders was IGD, with only three studies referencing GD as defined in ICD-11. Notably, just six experimental studies included abstinence control. We advocate for an expansion of research on withdrawal symptoms, particularly through experimental studies that implement abstinence within experimental groups and offer alternative operationalizations beyond dominant self-assessment measures.
