Mindfulness-based Neurofeedback to Reduce Negative Thinking in CHARMS Adolescents (CHARMS)

February 10, 2026 updated by: Anne Eden Evins, Massachusetts General Hospital

Effect of Network-based Real Time Neurofeedback Augmentation of Mindfulness Practice on Recurrent Negative Thinking in Adolescents at Risk for Serious Mental Illness

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.

Detailed Description

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.

Experimental: Active mindfulness-based neurofeedback (Active mbNF)

Participants will:

  • Receive a 45-minute mindfulness training
  • Receive two sessions of active mindfulness-based neurofeedback
Behavioral: Mindfulness Training
All participants will complete a single 45-minute mindfulness training at Visit 2, with a refresher prior to the second mbNF session at Visit 3. Clinically trained study staff will conduct the training with the aim of teaching "mental noting," a core mindfulness technique to be practiced and employed during neurofeedback. Mental noting is a major component of Vipassana (insight mindfulness meditation); its key principles include: "concentration", "observing sensory experience,'' "not 'efforting'", and "contentment".Specifically, participants will be taught to mentally label/note whatever sensation is most prominent in their sensory experience from moment to moment (e.g., seeing, hearing, feeling, thinking). Training will be personalized to identify scenarios in which mental noting can be applied in the context of each person's daily life, explaining the goal of using these strategies to manage distress in daily life.
Behavioral: Active mindfulness-based neurofeedback (Active mbNF)
Before the MRI scan, participants will practice mental noting by verbalizing their mental label with the study clinician providing feedback. Participants will then complete a silent practice of mental noting while viewing simulated neurofeedback. Participants will be trained until they feel competent to use mental noting in the scanner. During active mbNF (6 runs, 2.5 minutes each), participants will use mental noting with the aim of controlling visual feedback. Specifically, they will attempt to move the position of the white dot toward the (upper) red circle and away from the (lower) blue circle.
Sham Comparator: Sham mindfulness-based neurofeedback (Sham mbNF)

Participants will:

  • Receive a 45-minute mindfulness training
  • Receive two sessions of sham neurofeedback
Behavioral: Mindfulness Training
All participants will complete a single 45-minute mindfulness training at Visit 2, with a refresher prior to the second mbNF session at Visit 3. Clinically trained study staff will conduct the training with the aim of teaching "mental noting," a core mindfulness technique to be practiced and employed during neurofeedback. Mental noting is a major component of Vipassana (insight mindfulness meditation); its key principles include: "concentration", "observing sensory experience,'' "not 'efforting'", and "contentment".Specifically, participants will be taught to mentally label/note whatever sensation is most prominent in their sensory experience from moment to moment (e.g., seeing, hearing, feeling, thinking). Training will be personalized to identify scenarios in which mental noting can be applied in the context of each person's daily life, explaining the goal of using these strategies to manage distress in daily life.
Behavioral: Sham mindfulness-based neurofeedback
Before the MRI scan, participants will practice mental noting by verbalizing their mental label with the study clinician providing feedback. Participants will then complete a silent practice of mental noting while viewing simulated neurofeedback. Participants will be trained until they feel competent to use mental noting in the scanner. During sham mbNF, participants will view a visual display (white dot, red and blue circles) extracted from a previously acquired mbNF session. The display will be independent from brain activity in the sham condition and will simply mirror the stimuli observed by those in the mbNF group. This ensures participants across groups are viewing equivalent stimuli for the same amount of overall time.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in repetitive negative thinking (RNT)
Time Frame: 2 weeks
Perseverative Thinking Questionnaire- Child Version (PTQ-C), is a content-independent measure of RNT, with 15 items, rated on a 5- point scale (never, almost never, sometimes, often, almost always), with excellent internal consistency, Cronbach's alpha=0.95, in both clinical and non-clinical samples, validated and normed in clinical and non-clinical adolescent and young adult samples as a transdiagnostic research tool that has been shown to predict MDD. Higher scores indicate greater RNT.
2 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in psychotic symptom severity
Time Frame: 2 weeks
Psychotic symptoms will be assessed using the Brief Psychiatric Rating Scale (BPRS), a well validated, 18-item, interview-based measure of positive and negative psychotic, depressive, and general psychiatric symptoms that is sensitive to treatment effects and is included in the PhenXToolkit. Scores for each item range from 1 (not present) and 7 (extremely severe). Higher scores indicate greater severity of psychotic symptoms.
2 weeks
Change in depressive symptom severity
Time Frame: 2 weeks
Depressive symptoms will be assessed by the Quick Inventory of Depressive Symptoms - (QIDS-C) for participants ages 18 and older and the Quick Inventory of Depressive Symptoms - Adolescent Version (QIDS-A17) for participants under 18 years old. The QIDS is a 17-item clinician rated scale that assesses mood, sleep, appetite, and suicidal ideation. Higher scores indicate greater depressive symptom severity.
2 weeks
Change in social and occupational functioning
Time Frame: 2 weeks
Social and occupational functioning will be assessed using the Social and Occupational Functioning Assessment Scale (SOFAS). It focuses exclusively on the individual's level of social and occupational functioning and is not directly influenced by the overall severity of the individual's psychological symptoms. Scores range from 0 to 100, with lower scores indicating greater levels of impairment.
2 weeks
Change in worry symptom severity
Time Frame: 2 weeks
The Penn State Worry Questionnaire will be used to assess RNT in the form of worry. The scale has a possible range from 0 to 42. Severity cutoffs are as follows: normal (0-15), at risk (top 3-7%; 16-18), clinically elevated (top 2%; 19+). Participants under 18 years old will be assessed using the Penn State Worry Questionnaire for Children.
2 weeks
Change in rumination symptom severity
Time Frame: 2 weeks
The Rumination Response Scale (RRS) will be used to assess RNT in the form of depressive content and response styles for depression. The scale is 22 items and each item is rated on a 4-point Likert scale, with responses ranging from 1 (almost never) to 4 (almost always). Higher scores indicate more severe rumination responses.
