Teen Brain Online II: Understanding How Social Media Affects the Teen Brain

Study Summary

There has been much interest in the potential role of social media (SM) use in driving a current mental health crisis among teens, with a dire need for evidence that goes beyond self-report. One important avenue is to understand the role of the brain in driving the effects of SM use on emotional health and vice versa. However, there is almost no research addressing these questions, largely due to a lack of tasks that can probe the neural correlates of modern SM use. The goal of this clinical trial is to develop and validate a new developmentally-appropriate and ecologically-valid functional magnetic resonance imaging (fMRI) and eyetracking task, the TeenBrainOnline (TBO) Task, that is more realistic and similar to modern SM platforms. Participants will be 50 teens (ages 13-17) with depressive symptoms who will complete the final version of TBO task during fMRI with eye-tracking, an older Chatroom Interact (CHAT-I) Task, daily surveys of SM use, and measures of depressive symptoms. Our goal is to show that the task works by: * Demonstrating that it activates expected regions of the brain and visual attention biases toward feedback cues. * Showing that brain and eyetracking (visual attention) activity on the task explain variability in depressive symptoms at baseline and three months later, and work better than similar indices from an older task. * Showing that brain and eyetracking (visual attention) activity on the task are associated with real-world measures of social media use collected during daily surveys. Specifically, The investigators expect that teens whose brain and eyetracking activity suggests they are more sensitive to feedback on SM will report a social evaluation orientation toward social media use in daily life, such as engaging a lot in social comparison, worrying about missing out, and caring about getting a lot of likes and comments. Participants will be asked to: * complete a 10-15 minute screening call to determine eligibility for the study *

Primary Outcome

The investigators will measure neural activity (as measured by fMRI response) in regions within the Affective Salience network (ASN) in response to social threat and reward in the TBO and CHAT-I tasks. Average activation will be compared in each region between experiences of social reward, social threat, and neutral experiences as well as baseline.
