Congrats to @DanMirea4, who led a new paper published in @JAMAPsych! "The Reinforcement Effect of Social Media Likes in Depression" jamanetwork.com/journals/jam… Across 3 different Twitter datasets, we examined the effects of social media “likes” on posting behavior and their associations with depressive psychopathology. We found that greater symptoms were linked to *greater* tendency to be reinforced by likes. These results suggest that people with depression are more sensitive to positive social feedback (social reward) on social media. Given that lab studies tend to show the opposite pattern (blunted reward learning in depression), these findings reveal novel insights one can gain from analyses of naturalistic real-world behavior.
