Is Social Media Use Disorder a Thing?

Background: As understanding of addiction extends beyond substance misuse, various behavioral disorders may emerge as recognized mental health conditions, including social media use disorder (SMUD). To date, however, empirical research supporting SMUD as a distinct disorder is limited and inconsistent. The present study set out to compare the relative prevalence of elevated symptoms suggestive of SMUD between those with no mental health history and affective disorders (both unipolar depression and bipolar disorder). Methods: Participants were recruited online and completed questionnaires measuring social media use (SMU), symptoms of SMUD, depression and various psychosocial factors associated with social media use (i.e., loneliness, social support). Among those with affective disorders, we set out to identify sociodemographic and clinical features that distinguish those with comorbid SMUD (i.e., above the cut-off on the SMUD screening measure). Results: Five main findings emerged from our analyses: (1) SMUD appears unrelated to known forms of SMU; (2) Among those with no mental health history, SMUD does not present independently of elevated depressive symptoms; (3), No sociodemographic or clinical features distinguish those with clinical depression reporting comorbid SMUD; (4), Among those with bipolar disorder (BD), symptoms of hypo/mania do not distinguish those also reporting elevated SMUD symptoms; (5) And SMUD symptoms no longer differ across clinical groups after adjusting for depressive symptoms. Conclusions: Our findings suggest that SMUD is unrelated to active or passive SMU. Symptoms suggestive of SMUD may instead be a contemporary manifestation of depressive symptomology. These findings do not support the existence of SMUD as a bona fide mental health condition.
