Brief Summary
Rumination involves focusing on negative emotions repeatedly and is a risk factor for developing depression, anxiety, and self-injury. These negative outcomes increase in adolescence. The main goal of this study is to examine whether a mobile application designed to reduce rumination works with adolescents. The mobile application involves mindfulness exercises. Mindfulness means nonjudgmentally and deliberately paying attention. Adolescents will be randomly assigned to either the mindfulness group or a control group who uses a mobile application without mindfulness exercises. Both groups will use the app three times per day for three weeks and we will follow up with participants for six months. The investigators hypothesize that the mindfulness group will experience a reduction in rumination and symptoms of depression, anxiety and self-injury. They also expect that the mindfulness group will find the mobile app to be more engaging and will continue to use it beyond the 3 weeks.

Study Arms (2)
Mindfulness App
EXPERIMENTALGuided mindfulness exercises will be delivered via mobile app for three weeks.
Control condition
NO INTERVENTIONParticipants will use app for assessment for three weeks, but no mindfulness exercises will be delivered.
Interventions
Mindfulness exercises will last 1-12 minutes. Each one asks participants to focus on something (e.g., breath, sounds, physical sensations) using guided instruction.
Eligibility Criteria
You may qualify if:
- adolescent between the ages of 12 and 15 years
- at least moderate levels of rumination (mean score of 2 or above on a 1-4 scale) on the two screening questions
You may not qualify if:
- serious physical or cognitive disability that prevents adolescent from using a mobile device, because that is the intervention delivery method
- inadequate English proficiency to complete questionnaires
Contact the study team to confirm eligibility.
