Abstract The relationship between Gaming Disorder (GD) and the experience of functional impairments has received considerable theoretical attention in the recent past and current diagnostic approaches underscore the centrality of functional impairments as a requirement for GD diagnosis.

Abstract Background: ‘Gaming Disorder’ (GD) is now an officially recognized mental health disorder according to the World Health Organization (WHO) framework while ‘Internet Gaming Disorder (IGD) remains as a tentative disorder as per the American Psychiatric Association (APA) framework.

Abstract Previous research on gaming disorder (GD) has highlighted key methodological and conceptual hindrances stemming from the heterogeneity of nomenclature and the use of non-standardized psychometric tools to assess this phenomenon.

Abstract Background: Videogame addiction has been suggested as a tentative disorder in 2013 by the American Psychiatric Association (APA) and was recently officially recognized as a mental health disorder by the World Health Organization (WHO).

Abstract The use of social networking sites (SNSs) is rapidly increasing as billions of individuals use SNS platforms regularly to communicate with other users, follow the news, and play browser games.

Abstract Background and aims: Previous studies focused on examining the interrelationships between social networking site (SNS) addiction and Internet gaming disorder (IGD) in isolation. Moreover, little is known about the potential simultaneous differential effects of SNS addiction and IGD on psychological health.

Abstract In the latest (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), Internet Gaming Disorder (IGD) was included as a tentative disorder worthy of future research. Since then, several psychometric instruments to assess IGD have emerged in the literature, including the nine-item Internet Gaming Disorder Scale–Short-Form (IGDS9-SF), the most brief tool available to date.

Abstract Despite the large growth on gaming behaviour research, little has been done to overcome the problem stemming from the heterogeneity of gaming addiction nomenclature and the use of non-standardised measurement tools.
