Abstract

Objective: To evaluate whether mindfulness-based interventions (MBIs) reduce post-traumatic stress disorder (PTSD) symptoms in military veterans and to situate MBIs relative to guideline-recommended, trauma-focused psychotherapies.
Methods: Narrative synthesis of randomized/controlled trials (RCTs), systematic reviews/meta-analyses, and clinical practice guidelines relevant to veterans (search window emphasized 2015–2025).
Results: Multiple veteran-focused RCTs report clinically meaningful PTSD symptom reductions from MBIs, including Mindfulness-Based Stress Reduction (MBSR), Mantram Repetition Program (MRP), and Loving-Kindness Meditation (LKM). The landmark veteran RCT found MBSR superior to present-centered group therapy and achieving remission in a higher proportion of participants. MRP outperformed present-centered therapy on PTSD severity and insomnia. LKM was noninferior to group Cognitive Processing Therapy (CPT) for PTSD reduction and showed advantages for depression in secondary outcomes. PMC Meta-analytic summaries generally show small-to-medium effects of MBIs for PTSD, with heterogeneity by protocol and study quality. PMCScienceDirectMedNexus
Conclusions: MBIs can reduce PTSD symptoms in veterans and may be acceptable alternatives or adjuncts for those who decline or do not respond to trauma-focused therapies. However, U.S. VA/DoD guidelines place MBIs (specifically MBSR) as “Weak for”—supportive but secondary to strongly recommended trauma-focused psychotherapies (CPT, EMDR, PE). healthquality.va.gov+1

1. Background and Rationale

PTSD prevalence is elevated among veterans, and evidence-based first-line treatments are trauma-focused psychotherapies such as Cognitive Processing Therapy (CPT), Eye Movement Desensitization and Reprocessing (EMDR), and Prolonged Exposure (PE). The 2023 VA/DoD Clinical Practice Guideline recommends these with Strong for strength. healthquality.va.gov Yet, barriers (stigma, avoidance, readiness, comorbidities, logistical constraints) mean many veterans decline, discontinue, or derive incomplete benefit from trauma-focused options—creating a role for acceptable, skills-based, non-trauma-focused alternatives like MBIs. The updated VA/DoD guideline explicitly suggests MBSR for PTSD (Weak for), reflecting supportive but lower-certainty evidence. healthquality.va.gov

2. What Counts as “Mindfulness” in This Literature?

MBIs used with veterans include:

  • MBSR (8-week group course emphasizing attention regulation and nonjudgmental awareness). healthquality.va.gov

  • Mantram Repetition Program (MRP) (portable attention-anchoring via silently repeating a sacred word/phrase; often taught in VA).

  • Loving-Kindness Meditation (LKM) (cultivating prosocial affect; tested against CPT). PMC
    Some trials also evaluate Transcendental Meditation versus exposure therapy and other meditative approaches within VA/DoD evidence tables. healthquality.va.gov

3. Efficacy: What Do Veteran-Focused RCTs Show?

3.1 Mindfulness-Based Stress Reduction (MBSR)

  • Polusny et al., 2015 (JAMA): In 116 veterans with PTSD, group MBSR produced greater reductions in PTSD Checklist–Civilian Version (PCL-C) scores versus present-centered group therapy at post-treatment and higher remission rates (defined by CAPS).

  • This trial is repeatedly cited by the VA/DoD guideline as pivotal to the Weak for recommendation of MBSR. healthquality.va.gov

3.2 Mantram Repetition Program (MRP)

  • Bormann et al., 2018 (Am J Psychiatry): Among veterans with PTSD, MRP led to greater reductions in PTSD symptom severity (PCL) and insomnia than present-centered therapy.

3.3 Loving-Kindness Meditation (LKM)

  • Kearney et al., 2021 (JAMA Netw Open, corrected): Group LKM was noninferior to group CPT for reducing PTSD symptoms and showed better depression outcomes in secondary analyses; session attendance favored LKM, suggesting acceptability. PMC

3.4 Other Meditation Approaches

  • The VA/DoD evidence tables include trials of non-trauma-focused meditation (e.g., Transcendental Meditation) compared with exposure therapy, indicating symptom improvement but mixed comparative findings; the guideline did not elevate these to strong recommendations. healthquality.va.gov

Bottom line from RCTs: Multiple, independently developed MBIs reduce PTSD symptoms among veterans, sometimes matching active comparators and improving engagement; durability varies and head-to-head data vs first-line trauma-focused therapy remain limited. PMC

4. Meta-Analytic Evidence (Including Veterans)

  • 2024 meta-analysis (Health Psychol Open): Focused on veterans, found that MBSR improves PTSD and depression outcomes (small-to-medium effects). PubMed

  • 2024 meta-meta-analysis (J. Anxiety Disorders): Pooled across MBIs and populations, estimated a medium effect on PTSD symptoms (SMD≈0.41). ScienceDirect

  • 2022–2023 syntheses: Show positive but heterogeneous results; effects are generally smaller than those for trauma-focused psychotherapies, and follow-up durability is less certain. PMCFrontiers

5. Guidelines and Clinical Positioning

  • VA/DoD 2023–2024 update:

    • Strong for: CPT, EMDR, PE (first-line). healthquality.va.gov

    • Weak for: MBSR for PTSD—acknowledges benefits with modest certainty; appropriate for veterans who prefer MBIs or decline trauma-focused therapies. healthquality.va.gov

    • Insufficient evidence: for several other “mind-body” modalities as monotherapies. healthquality.va.gov

6. Mechanisms of Action (Hypothesized)

  • Attention regulation & decentering: Reduced reactivity to trauma cues and intrusive memories.

  • Arousal modulation: Breathing/awareness practices may down-shift sympathetic activation, improving hyperarousal and sleep.

  • Emotion regulation & self-compassion: Particularly salient in LKM; may reduce avoidance and negative mood states that maintain PTSD. These mechanisms are discussed in the guideline narrative and mechanistic pilot work in veterans. healthquality.va.gov

7. Safety and Acceptability

MBIs are generally low risk, group-deliverable, and often show better session attendance than some trauma-focused protocols in head-to-head formats (e.g., LKM vs CPT). That said, symptom activation can occur; programs should include trauma-informed instructors and monitoring. PMC

8. Practical Implications for Care Systems

  1. Offer MBIs as part of stepped or preference-based care: For veterans reluctant to engage in trauma processing, MBIs can be a credible first step or adjunct. healthquality.va.gov

  2. Program selection matters: Use manualized, studied protocols (e.g., MBSR, MRP, LKM) rather than ad-hoc mindfulness classes. PMC

  3. Integrate with first-line care: For veterans willing to engage in CPT/EMDR/PE, those remain the highest-value options; MBIs can support emotion regulation, sleep, and adherence. healthquality.va.gov

  4. Delivery formats: Group-based, VA-embedded programs and hybrid/virtual options can improve reach; guideline notes broader technology-based treatment considerations. healthquality.va.gov

9. Limitations of the Evidence

  • Heterogeneity: Protocols, control conditions, and outcome measures vary widely, complicating pooled estimates. ScienceDirect

  • Durability: Long-term follow-up beyond 3–6 months is sparse; effects sometimes attenuate. Frontiers

  • Comparator stringency: Many trials use present-centered or waitlist controls; fewer head-to-head comparisons with first-line trauma-focused therapies exist (LKM-vs-CPT is a notable exception). PMC

10. Research Priorities

  • Noninferiority and dismantling trials comparing MBIs to CPT/EMDR/PE, with mediation (e.g., attentional control, decentering) and maintenance phases.

  • Implementation science in VA settings: uptake, fidelity, and equity across rural/urban and diverse veteran groups.

  • Adjunctive strategies: MBIs before or alongside trauma-focused therapy to enhance retention and outcomes. The VA/DoD guideline similarly calls for expanded comparative-effectiveness work on complementary interventions. healthquality.va.gov

11. Conclusion

The answer to “Can mindfulness reduce PTSD symptoms in veterans?” is yes—with the caveat that effects are typically small-to-medium, protocol-dependent, and supported by RCTs of MBSR, MRP, and LKM. For many veterans, MBIs offer an acceptable, low-risk path to symptom reduction, especially when first-line trauma-focused therapies are declined or incomplete. However, when feasible and acceptable, CPT/EMDR/PE remain the treatments with the strongest evidence and guideline support. healthquality.va.gov

Clinical takeaway for practice

  • Offer MBIs (e.g., MBSR, MRP, LKM) when veterans prefer non-trauma-focused options or as skills training to support trauma-focused therapy.

  • Set expectations: benefits are real but typically smaller than trauma-focused therapies; plan for relapse-prevention/maintenance.

  • Measure outcomes (e.g., PCL-5, PHQ-9, ISI) to monitor response and adjust care accordingly—consistent with VA/DoD guideline principles. healthquality.va.gov
