Mindfulness-based Neurofeedback to Reduce Negative Thinking in CHARMS Adolescents

The study will test the hypothesis that mindfulness-based neurofeedback (mbNF) will improve repetitive negative thinking and social and role functioning over sham neurofeedback in adolescents at risk for serious mental illness. To do so, 90 adolescents ages 14-21 with elevated repetitive negative thinking will be enrolled into a double-blind randomized clinical trial of sessions of mindfulness training with either active mindfulness-based neurofeedback or sham neurofeedback and three months of mindfulness practice and follow up.

Approximately 90 at-risk adolescents ages 14-21 years old will be enrolled in a double-blind, randomized clinical trial. All participants will undergo a baseline clinical assessment (Visit 1), which will serve as an important baseline for daily symptom fluctuation and use of mindfulness strategies prior to training. Approximately 1-2 weeks after the baseline assessments, all participants will complete an in-person visit (Visit 2) in which they will complete a brief MRI scan (resting state localizer) and a 45-minute mindfulness training. After the mindfulness training, participants will be randomized in a 1:1 ratio to receive either active or sham neurofeedback (n=45 each group). Randomization will be stratified by information obtained at the baseline assessment: biological sex, prior daily/near daily mindfulness practice for 8 weeks or more. A study staff member with no participant contact will create randomization tables in REDCap to alloacte participants to either active or sham mbNF. Participants and staff will remain blinded to assignment. Participants will then complete another MRI session what will include resting state scans as well as the active or sham mbNF. Approximately 1-2 weeks later, participants will return for another in-person visit (Visit 3) that includes a mindfulness refresher and repeats the procedures of Visit 2. Participants will briefly rate their mindfulness practice daily for three months using a brief, online survey. At 1-, 3- and 12-months post-neurofeedback, participants will complete self-report and clinician-rated assessments to probe repetitive negative thinking and prodromal psychiatric symptoms.
