Clinical Trial Summary

A growing body of research implicates rumination as being a transdiagnostic risk factor involved in the development of depression and anxiety in youth. Critically, mindfulness meditation has shown significant promise in targeting rumination, and ultimately improving depressive and anxiety symptoms. Mindfulness apps offer a convenient and cost-effective means for accessing mindfulness training, while being interactive and engaging for youth. Despite their growing popularity among teens, strikingly little research has been conducted on these apps. Two critical questions have yet to be addressed: (1) what are the underlying neural and cognitive mechanisms that account for the beneficial effects of these apps and (2) for whom is app-based mindfulness well-suited. To address these gaps, adolescents (ages 13-18) will be randomly assigned to an app-delivered mindfulness course vs. a control condition and will complete pre- and post-intervention resting state functional magnetic resonance imaging (fMRI) scans to probe static and dynamic functional connectivity within - and between - brain networks strongly implicated in mindfulness training and rumination. In addition, cognitive tasks will be administered at pre- and post-intervention to assess attentional control abilities putatively enhanced by mindfulness training. Finally, mindfulness skills and changes in rumination will be assessed via smartphone-based ecological momentary assessment (EMA). First, the investigators will test whether changes in (1) brain functional connectivity, (2) attentional control and (3) acquisition and use of mindfulness skills mediate between-group (i.e., app vs. control) differences in the reduction of rumination. Second, the investigators will test whether a machine learning model incorporating baseline clinical, demographic, and psychosocial characteristics can be used to identify which adolescents are predicted to benefit from app-based mindfulness training.

Intervention

Behavioral:
Mindfulness (Headspace) App
The Headspace app consists of guided mindfulness meditations and is available for both Apple iOS and Android devices. For the proposed study, participants will be instructed to complete the app's most popular introductory program which consists of three levels ("Basics 1-3"), with each level comprising 10 sessions (30 in total) over 30 days. The program is intended to introduce the key principles and techniques of mindfulness (including focused meditation on the breath, body scanning, and noting), and strategies for applying mindfulness to daily life.
Active Control Condition ("Recharge" condition delivered in Headspace app)
The majority of prior research on mindfulness interventions has relied on single-arm designs or wait-list controls conditions, rather than active control conditions. Accordingly, we will include a structurally-equivalent active control condition, delivered via the same Headspace app. Specifically, the control condition will consist of 30 guided "Recharge" sessions led by Andy Puddicombe (i.e., structurally equivalent to the Mindfulness app). The sessions are the same length as the interventions (Basics) sessions and also delivered via the Headspace app, thus closely matching the mindfulness intervention across key attributes. Specifically, user flow through the app is identical in both the mindfulness and control conditions, differing only in session content. The Recharge sessions include guide reflections, guided positive imagery, problem solving and daily planning. The chosen excerpts exclude any content which feature guided mindfulness exercises.
