An eight-week mindfulness-based stress reduction program added to standard inpatient care was associated with faster behavioral responses to fearful faces and selective changes in a late neural marker of emotional processing among adolescents receiving live-in mental health treatment, according to a pilot randomized controlled trial published in Child and Adolescent Psychiatry and Mental Health.
The research team, led by Fan Peng and Anthony Singhal with colleagues including Andrea T. Shafer, Sunita Vohra, K. Jessica Van Vliet and Florin Dolcos, enrolled 31 adolescents aged 12 to 18 years who were admitted to a voluntary, live-in mental health program. Fourteen participants were assigned to receive the mindfulness-based stress reduction, or MBSR, program alongside routine care, while 17 continued with standard care alone. The trial protocol was registered with ClinicalTrials.gov under identifier NCT01307943.
Adolescence is a sensitive period for emotional and cognitive development, and the authors note that young people with ADHD and affective disorders face heightened risk for mental health challenges. While MBSR has been shown to improve emotion regulation and cognition in healthy populations, its effects in clinically complex adolescents have remained poorly understood, which motivated the exploratory design of this trial.
Participants completed a modified emotional oddball task while the researchers recorded both reaction times and event-related potentials, or ERPs, which are brain electrical responses time-locked to stimuli. In this paradigm, participants viewed emotional images interspersed with target stimuli, allowing the team to measure how quickly and how strongly the brain responded to fear-related material and to behaviorally relevant events.
On the behavioral side, the MBSR group showed shorter baseline-adjusted reaction times specifically to fearful stimuli and to targets that followed other targets. The authors interpret this pattern as possibly reflecting improved task-relevant processing, meaning that the trained adolescents appeared to engage more efficiently with the items that mattered for the task at hand. Notably, the advantage was selective rather than global: it appeared for fear-related stimuli and particular target sequences, not across every condition.
The neural findings were similarly selective. ERP analyses detected no significant Group by Condition interactions for the P100 or P300 components, which index early sensory processing and attentional allocation respectively. In other words, the study found no evidence that MBSR broadly changed early-stage visual or attentional processing in these adolescents.
Where differences did emerge was at the Late Positive Potential, or LPP, a component often linked to sustained emotional processing. The MBSR group showed smaller baseline-adjusted LPP amplitudes for fearful stimuli, which the authors suggest may reflect attenuated sustained neural reactivity to threat. At the same time, the MBSR group showed larger LPP amplitudes for targets following fearful stimuli or other targets, a pattern the authors interpret as possible selective engagement with behaviorally relevant events.
Taken together, the authors propose that integrating MBSR into routine inpatient care may be associated with improved behavioral performance and selective modulation of later neural processing, potentially supporting rapid attentional engagement and efficient allocation of cognitive resources in adolescents with ADHD and affective disorders. They frame the results as evidence that mindfulness may have potential for supporting emotion regulation and attentional efficiency in clinical youth, while stressing that the findings are exploratory and arise from a small pilot sample.
The study’s limitations are explicit in the abstract: the authors call for larger-scale trials and for examination of the long-term durability of these effects. Because the trial was a pilot with 31 participants and the published version is an accepted manuscript subject to further edits, the reported patterns should be treated as preliminary signals rather than established clinical benefits. The full open-access article is available from the journal, and the publisher notes that the final Version of Record will replace the current accepted version.
