NCT03900416

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.
