Social Media Concerns Related to Emotional Experiences in Naturalistic Settings (SCREENS)

The objective of this study is to advance understanding of the relationships between social media use (SMU) and internalizing symptoms among a diverse sample of depressed and/or suicidal youth. Youth (ages 13-18) enrolled in the TX-YDSRN registry study will be recruited for participation in SCREENS. After reviewing the Information Sheet, participants will complete baseline measures assessing internalizing symptoms (e.g., depression, anxiety, suicidal ideation/behavior), and trauma history. They will then complete ecological momentary assessments (EMAs) twice daily for 30 days via the mHealth app, capturing internalizing symptoms, emotional responses to social media, and in-person social support. The mHealth app will also collect the amount of social media use during this 30-day period. From Month 1 through Month 6, participants will receive monthly self-report surveys administered through REDCap. 100 participants This study will enroll youth from the TX-YDSRN registry study who meet all the following criteria: * Be between 13 and 18 years of age at the time of enrollment. * Be currently enrolled in the TX-YDSRN registry study and willing to allow sharing of data from that study. * Own a smartphone and agree to download and use the study mHealth application for the duration of study participation. * Be willing and able to participate in all study requirements and allocate sufficient time to complete study questionnaires and measures.
