This plot shows the number of users in the Study 1 sample that self-described as 'addicted' to Instagram versus those who were 'at risk' of clinical addiction. The ratios for the addiction symptom scale are 9:371 and for the perceived addiction 69: 311, suggesting a much greater proportion of users self-perceive as addicted than are actually addicted to Instagram

Excited to see these studies (finally) published in Scientific Reports! ๐Ÿšจ

S1: More social media users perceived themselves as addicted than met clinical addiction criteria.

S2: Increasing perceived addiction hurt perceived control over use and increased self-blame for overuse.
