Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Mindfulness involves paying attention to the present moment without judgement. If negative emotions arise, one notices them and how the body is feeling without becoming caught up in the emotion so that it can pass. In adult clinical studies, intensive mindfulness practice has been associated with successful treatment of psychopathology, including preventing the recurrence of depression, possibly through reducing rumination. Research with adolescents has suggested that a brief mindfulness exercise can interrupt the ruminative process. Thus, mindfulness appears to be a promising strategy to reduce the tendency to ruminate and prevent psychopathology.
A diverse sample of 150 high-ruminating 12-15 year-olds will be recruited from the community and randomly assigned to a 3-week mobile mindfulness intervention or an ecological momentary assessment (EMA)-only control condition. In both conditions, adolescents will be notified to use the mobile app three times per day to complete EMA questions. Based on mood ratings, participants in the mindfulness condition have a chance to receive a brief mindfulness exercise (i.e., 1-12 minutes long) at each use. At pre- and post-intervention and three follow-up periods (6 weeks,12 weeks, and 6 months), participants and their parents will report on adolescent anxiety and depression. Adolescents will also report on self-injurious thoughts and behaviors (SITBs), trait rumination, and mindfulness. During the intervention period, participants will report on state levels of rumination, mindfulness, and mood using the app. Participants will also report on their satisfaction with the app, while their optional continued use of the app will be monitored electronically for 6 months following the intervention period. The investigators will test intervention effects using multilevel modeling, examining the role of both state- and trait-level mediators. Based on preliminary pilot data, the investigators expect that the mindfulness intervention will reduce symptoms, and we anticipate this effect to be due to the mediating role of decreased rumination.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Mindfulness App
Guided mindfulness exercises will be delivered via mobile app for three weeks.
Mindfulness App
Mindfulness exercises will last 1-12 minutes. Each one asks participants to focus on something (e.g., breath, sounds, physical sensations) using guided instruction.
Control condition
Participants will use app for assessment for three weeks, but no mindfulness exercises will be delivered.
No interventions assigned to this group
