A Randomized Controlled Trial of a Smartphone-Based Well-Being Training in Public School System Employees During the COVID-19 Pandemic

March 30, 2021 Matthew J. Hirshberg, Corrina Frye, Cortland J. Dahl et al. 5 citations preprint

A four-week smartphone-based meditation app (Healthy Minds Program) reduced psychological distress and improved well-being among school system employees during the COVID-19 pandemic. In a randomized wait-list controlled trial with 662 participants (64% teachers), those assigned to the app showed significantly larger reductions in distress immediately after the intervention and at a three-month follow-up, with similar benefits on secondary outcomes such as perseverative thinking and social connection. The app was equally effective for participants with elevated baseline anxiety and depressive symptoms, and no evidence of elevated adverse events was found. The program may offer a scalable approach to supporting educator mental health.

How Often Should I Meditate? A Randomized Trial Examining the Role of Meditation Frequency When Total Amount of Meditation is Held Constant

February 19, 2023 Kevin M. Riordan, Otto Simonsson, Corrina Frye et al. 2 citations preprint

A two-week compassion-based meditation intervention delivered via the Healthy Minds Program app led to improvements in psychological distress, experiential avoidance, fear of missing out, loneliness, and self-compassion among undergraduates with clinically elevated depression and/or anxiety. Participants were randomized to either one 20-minute meditation per day (Massed condition) or two 10-minute meditations per day (Distributed condition). Both groups showed similar improvements, with no significant differences between conditions on any outcome. When total daily meditation time is held constant, distributing practice across the day does not appear to influence outcomes for distressed beginners, supporting flexibility in meditation scheduling.

Is Informal Practice Associated with Outcomes in Loving-Kindness and Compassion Training? Evidence from Pre-Post and Daily Diary Assessments

February 10, 2023 Qiang Xie, Kevin M. Riordan, Scott A. Baldwin et al. 2 citations preprint

Among clinically distressed adults with no meditation experience who used a smartphone-based loving-kindness and compassion training program for two weeks, those who increased their informal meditation practice (using techniques outside formal sessions) showed greater reductions in psychological distress and loneliness from before to after the intervention, though no changes in empathy or prosociality were observed. Daily analyses indicated that more informal practice on a given day predicted lower distress the next day, but not lower loneliness. Distress and loneliness did not predict subsequent informal practice. The findings suggest that informal practice may play a causal role in reducing distress, but further experimental studies are needed.

Prevalence and Predictors of Self-Reported Adverse Experiences in Digital Meditation Training: 2 Randomized Controlled Trials

JMIR Mental Health June 12, 2026 Polina Beloborodova, Lillian M. Smith, Kevin M. Riordan et al.

About 28% of distressed college students and 10% of distressed US adults reported at least one adverse experience during a digital meditation program, but rates did not differ between those who completed guided meditations and those who did not, suggesting the experiences were not caused by meditation itself. Higher baseline depression, anxiety, loneliness, experiential avoidance, and perceived barriers to meditation predicted more adverse experiences. Among those reporting adverse experiences, roughly 90% were glad to have learned to meditate. Participants used diverse coping strategies, often drawing on skills taught in the program. The findings indicate that adverse experiences during meditation training may reflect preexisting distress rather than iatrogenic harm.
