A randomized trial with 130 participants tested whether the Five Facet Mindfulness Questionnaire (FFMQ) validly measures dispositional mindfulness. The study included three groups: mindfulness-based stress reduction (MBSR), an active control condition (Health Enhancement Program, HEP) that did not teach mindfulness meditation, and a waitlist control. At baseline, FFMQ facets correlated with measures of psychological symptoms and well-being, providing partial evidence for convergent validity. FFMQ scores increased for MBSR relative to the waitlist, but they also increased for HEP relative to the waitlist, and MBSR and HEP did not differ from each other. The FFMQ thus failed to show discriminant validity, raising questions about its ability to specifically measure mindfulness.

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.

A four-week smartphone-based meditation intervention reduced psychological distress during the early COVID-19 pandemic. Among 662 adults, most of whom reported clinical levels of anxiety or depressive symptoms, the intervention improved four proposed mediators—mindful action, loneliness, cognitive defusion, and purpose—measured five times during the program and at three-month follow-up. Each mediator individually accounted for 22.2% to 64.5% of the intervention's effect on later distress. When all mediators were analyzed together, only reduced loneliness remained a significant pathway, explaining 70.0% of the combined indirect effect. Multiple psychological mechanisms likely contribute to the benefits of digital meditation interventions.

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.

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.

Brief, informal meditation practices done during daily activities may help make meditation-based interventions more effective and accessible. Interviews with 17 participants after a 4-week smartphone meditation program revealed four themes: reported benefits, how they integrated practice into daily life, barriers to practice, and recommended facilitators. Barriers included lack of reminders and social support; facilitators included personalized app features and repeating intervention content. Addressing these factors could increase engagement with informal practice.
