Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research study is to learn more about social media usage and its relation to emotions, biology, and mental health. Participants will complete daily assessments (5 times a day) over the course of 11 days in which they will report on their social media use, behaviors, and mood. During the first 4 days participants will be asked to continue using social media as typical. In the second half (7 days) participants will be randomized to social media usage groups (0 minutes, 30 minutes, 1 hour, 2 hour, 3 hours). There will be mental health and well-being measures provided at the beginning and end of the study. Lastly, to better understand how social media usage effects underlying mechanisms of stress, participants will be asked to provide saliva samples for 3 nights (pre, mid, and post) to assess for basal cortisol levels.
