A Self-Guided App-Based Mindfulness Intervention for Racially and Ethnically Minoritized Individuals Who Experience Discrimination-Related Mental Health Symptoms: Randomized Controlled Trial.

TL;DR

A self-guided app-based mindfulness intervention was effective and feasible in reducing discrimination-related stress, anxiety, and depressive symptoms among racially and ethnically minoritized individuals compared to treatment as usual.

Key Findings

The DMHI group experienced significantly greater reductions in stress compared to the TAU group by end of the 4-week program.

  • Stress reduction: β=-4.52, 95% CI -6.54 to -2.51; FDR-adjusted P<.001
  • Treatment effect size: pseudo-R²=.41
  • 61% of DMHI participants (49/80) achieved a minimal clinically significant difference (MCID) in stress
  • Multilevel regression models with false discovery rate correction were used to examine mean differences between groups

The DMHI group experienced significantly greater reductions in anxiety compared to the TAU group.

  • Anxiety reduction: β=-3.31, 95% CI -4.89 to -1.74; FDR-adjusted P<.001
  • Treatment effect size: pseudo-R²=.45
  • 48% of DMHI participants (38/80) achieved a minimal clinically significant difference (MCID) in anxiety

The DMHI group experienced significantly greater reductions in depressive symptoms compared to the TAU group.

  • Depression reduction: β=-2.84, 95% CI -4.57 to -1.12; FDR-adjusted P=.004
  • Treatment effect size: pseudo-R²=.53
  • 54% of DMHI participants (43/80) achieved a minimal clinically significant difference (MCID) in depression

The app-based mindfulness intervention demonstrated high uptake, with all DMHI participants downloading and using the app.

  • 100% of DMHI participants (80/80) downloaded and used the app
  • Participants used the app an average of 16.83 (SD 7.8) days over the 4-week program
  • Participants completed an average of 24.85 (SD 23.3) meditations
  • Total average meditation time was 238.67 (SD 260.7) minutes

Overall study dropout was low at 8%, though most dropouts occurred in the intervention group.

  • 12 of 155 total participants (8%) dropped out of the study
  • Most dropouts occurred in the intervention group: 11/80 (14%)
  • Participants in the TAU group had very low dropout: 1/75 participants

Participants in the DMHI group reported high satisfaction with the intervention by end of treatment.

  • Mean treatment satisfaction score was 23.14 (SD 4.9)
  • Satisfaction was assessed using a self-reported treatment satisfaction measure at end of program
  • Feasibility outcomes including satisfaction were examined descriptively

The study sample was composed of racially and ethnically minoritized individuals who are significantly underrepresented in digital mental health intervention research.

  • Total sample: 155 participants, mean age 27.28 (SD 9.6) years
  • Racial/ethnic composition: 38.7% Latinx, 37.4% Asian, 11.6% Black, 10.3% Multiracial, 2% Native American
  • Participants were randomized to DMHI (n=80) or TAU (n=75)
  • REMs are described as 'significantly underrepresented in the overall DMHI and mindfulness-based DMHI literature'

Racially and ethnically minoritized individuals who experience discrimination are at elevated risk for stress, anxiety, and depression, and are underserved by existing digital mental health interventions.

  • Discrimination exposure is identified as a risk factor for developing stress, anxiety, and depression in REMs
  • DMHIs are noted as a potential means of making evidence-based treatments such as mindfulness available to these groups
  • Underrepresentation of REMs in DMHI literature limits understanding of effectiveness and feasibility for these populations

What This Means

This research suggests that a smartphone app delivering self-guided mindfulness meditation over four weeks can meaningfully reduce stress, anxiety, and depression symptoms in people from racially and ethnically minoritized groups who experience discrimination. In the trial, 155 participants — including Latinx, Asian, Black, Multiracial, and Native American individuals — were randomly assigned either to use the mindfulness app daily for four weeks or to seek mental health support on their own. Those using the app showed significantly greater improvements across all three mental health outcomes, with effect sizes described as large, and more than half of app users reached a level of improvement considered clinically meaningful for stress and depression. The study also found the app to be highly feasible: every person assigned to the app actually downloaded and used it, participants meditated for nearly four hours on average across the program, and most reported being satisfied with the experience. Dropout from the overall study was low at 8%, though slightly higher in the app group (14%) than the control group. These engagement numbers suggest that this type of self-guided digital tool is both accessible and acceptable to these communities. This research matters because racially and ethnically minoritized people are rarely included in studies of digital mental health tools, making it unclear whether those tools actually work for them. This trial provides evidence that a self-guided, app-based mindfulness program can be an effective and practical option for addressing the mental health impacts of discrimination, potentially offering a low-barrier, scalable way to improve mental health equity for communities that are often underserved by traditional mental health services.
