Toward the classification of social media use disorder: Clinical characterization and proposed diagnostic criteria

Empirical studies and theoretical models highlight that problematic use of social media can lead to significant
functional impairments in several domains, such as social, relational, occupational, and psychological functioning, as well as physical health. However, social media use disorder is not currently recognized as an official disorder in major diagnostic systems, limiting comparability among studies, precise prevalence estimation, and ad-hoc preventive and treatment program development. The present work aims to classify social media use disorder as a pathological condition sharing main mechanisms and maladaptive patterns with addictive behaviors. We discuss diagnostic criteria for social media use disorder by integrating peculiar features of this maladaptive behavior with criteria for substance use disorders and behavioral addictions from major diagnostic systems (i.e., DSM-5 and ICD-11). Moreover, we address some controversies related to the classification of social media use disorder as a behavioral addiction and highlight literature findings indicating social media use disorder shares main alterations in mechanisms and processes characterizing addiction (i.e., maladaptive activation of reward systems and impairment of inhibitory control mechanisms). Despite the lack of studies including clinical populations and the need for future research to validate the proposed criteria and refine knowledge of the mechanisms underlying this condition, our work provides a structured framework for classifying and identifying social media use disorder.
