概要	The Social Media Disorder Scale (SMD Scale) is a 9-item self-report measure developed by van den Eijnden and colleagues in 2016 to assess problematic social media use characterized by loss of control, withdrawal, tolerance, and conflict—mirroring criteria from behavioral addiction frameworks. It identifies individuals whose engagement with social media platforms has reached clinically concerning levels that interfere with daily functioning.	The FoMO Scale is a 10-item self-report instrument that measures the extent to which individuals experience anxiety or apprehension about missing out on social events, experiences, or information shared by others, particularly in social media contexts. Developed by Przybylski and colleagues in 2013, it quantifies this contemporary psychological phenomenon that has become increasingly relevant with the proliferation of digital communication platforms.
