Challenges to Enrollment and Participation in Mindfulness-Based Stress Reduction Among Veterans: A Qualitative Study

Telehealth Mindfulness-Based Interventions for Chronic Pain: The LAMP Randomized Clinical Trial

Importance

Although mindfulness-based interventions (MBIs) are evidence-based treatments for chronic pain and comorbid conditions, implementing them at scale poses many challenges, such as the need for dedicated space and trained instructors.

Objective

To examine group and self-paced, scalable, telehealth MBIs, for veterans with chronic pain, compared to usual care.

Design, Setting, and Participants

This was a randomized clinical trial of veterans with moderate to severe chronic pain, recruited from 3 Veterans Affairs facilities from November 2020 to May 2022. Follow-up was completed in August 2023.

Interventions

Two 8-week telehealth MBIs (group and self-paced) were compared to usual care (control). The group MBI was done via videoconference with prerecorded mindfulness education and skill training videos by an experienced instructor, accompanied by facilitated discussions. The self-paced MBI was similar but completed asynchronously and supplemented by 3 individual facilitator calls.

Main Outcomes and Measures

The primary outcome was pain-related function using the Brief Pain Inventory interference scale at 3 time points: 10 weeks, 6 months, and 1 year. Secondary outcomes included biopsychosocial outcomes: pain intensity, physical function, anxiety, fatigue, sleep disturbance, participation in social roles and activities, depression, patient ratings of improvement of pain, and posttraumatic stress disorder.

Results

Among 811 veterans randomized (mean [SD] age, 54.6 [12.9] years; 387 [47.7%] women), 694 participants (85.6%) completed the trial. Averaged across all 3 time points, pain interference scores were significantly lower for both MBIs compared to usual care (group MBI vs control difference: -0.4 [95% CI, -0.7 to -0.2]; self-paced vs control difference: -0.7 [95% CI, -1.0 to -0.4]). Additionally, both MBI arms had significantly better scores on the following secondary outcomes: pain intensity, patient global impression of change, physical function, fatigue, sleep disturbance, social roles and activities, depression, and posttraumatic stress disorder. Both group and self-paced MBIs did not significantly differ from one another. The probability of 30% improvement from baseline compared to control was greater for group MBI at 10 weeks and 6 months, and for self-paced MBI, at all 3 time points.

Conclusions and Relevance

In this randomized clinical trial, scalable telehealth MBIs improved pain-related function and biopsychosocial outcomes compared to usual care among veterans with chronic pain. Relatively low-resource telehealth-based MBIs could help accelerate and improve the implementation of nonpharmacological pain treatment in health care systems.

Virtual Mindfulness-Based Therapy for the Management of Endometriosis Chronic Pelvic Pain: A Novel Delivery Platform to Increase Access to Care

OBJECTIVES

This study assessed the effectiveness of a virtual mindfulness-based stress reduction (MBSR) program to improve quality of life and pain in people with endometriosis.

METHODS

This was a multiple-method, before and after study design. Fifteen patients with a clinical or surgical diagnosis of endometriosis were recruited from a Canadian outpatient gynaecology clinic. Participants completed the Endometriosis Health Profile, a validated survey tool, and a pain medication use questionnaire before and after a virtual 8-week MBSR program run by an experienced social worker. A focus group was held upon completion of the program to assess participants' experiences using mindfulness for management of endometriosis symptoms. Quantitative data was analyzed with paired-samples t tests. Qualitative data was thematically analyzed.

RESULTS

A total of 67% of people enrolled completed the MBSR course (10/15). Following the MBSR program, participants had a statistically significant decrease in 4 components of the Endometriosis Health Profile: control and powerlessness (P = 0.012), emotional well-being (P = 0.048), social support (P = 0.030), and self-image (P = 0.014). There was no change in pain scores or medication use. Participants felt the program's benefits came from a sense of community, education about their condition, and application of mindfulness tools when approaching pain. Participants felt more comfortable with the virtual format over in-person sessions.

CONCLUSIONS

A virtual MBSR course can improve quality of life domains in people with endometriosis. The virtual format was effective and preferred by participants. Virtual MBSR programs may increase access to this type of care.

Women veteran transition mental health and well-being support group programs: A scoping review

BACKGROUND

The military is a male-dominated environment and culture in which women veterans can experience significant institutional prejudice. Transition can be confusing and isolating for women veterans. Group programs are an important source of transition support. However, we know little about the specific group program needs of women veterans.

OBJECTIVES

To examine mental health and well-being support group programs delivered to women veterans, to understand what they value and find most helpful.

ELIGIBILITY CRITERIA

Women military veterans (all types); empirical studies using any design; published between 1990 and 2022; group programs focused on transition issues (such as housing, employment, education, physical health, mental health).

SOURCES OF EVIDENCE

Peer-reviewed journals and theses.

CHARTING METHODS

Six databases searched: Medline (via Ovid SP), PsycINFO (via Ovid SP), EmCare (via Ovid SP), CINAHL, Scopus, and ProQuest.

RESULTS

There was significant heterogeneity across 35 included studies in type of groups, program content and structure, length of sessions, measurement of impact, follow-up, and so forth. Most programs were delivered face to face. Physical health and preventative healthcare were important topics for women veterans, particularly reproductive health, mental health, and chronic pain. Groups that included physical activity, creative arts, and alternative therapies were beneficial to women's physical and mental health. Strengths-based women-only groups, facilitated by women, that created safe spaces for women veterans to share their experiences, enhanced self-expression, agency, and self-empowerment. This was particularly important for women who had experience military sexual trauma.

CONCLUSION

This review found a small but diverse range of group programs available for women veterans. Many program evaluations were of moderate or low quality and lacked sufficient information to determine whether benefits were sustained over time. No studies involved Australian women veterans. Despite these concerns, this review highlighted several useful lessons that could help inform improved design, delivery, and evaluation of group programs for women veterans.

Mindfulness-Based Stress Reduction (MBSR) for Chronic Pain Management in the Community Pharmacy Setting: A Cross-Sectional Survey of the General Public's Knowledge and Perceptions

Patient access to mindfulness-based stress reduction (MBSR), a complementary and integrative health approach that is proven to reduce chronic pain, can be increased via community pharmacy-based implementation. However, the general public's awareness and preferences regarding MBSR as a treatment option for chronic pain, including provider roles (pharmacist vs. non-pharmacist), are unclear. Therefore, the purpose of this study was to assess the U.S. general public's knowledge, attitudes, barriers, and programmatic preferences regarding MBSR for chronic pain management, particularly in the community pharmacy setting. A cross-sectional, anonymous online survey was distributed to U.S. adults ≥18 years via the Amazon Mechanical Turk (MTurk) online survey platform. The survey instrument was informed by Anderson's framework for health service utilization. Measures were assessed using multiple-choice and 5-point Likert-type scales (1 = strongly disagree, 5 = strongly agree). Primary outcome measures included: (1) knowledge and awareness of MBSR (12-items); (2) confidence in seeking out MBSR for pain (5-items); (3) barriers to receiving MBSR (11-items); (4) beliefs about MBSR in general (12-items); (5) beliefs about community pharmacy-delivered MBSR (15-items); and (6) preferences for MBSR classes/programs (6-items). Outcomes were analyzed using descriptive statistics, and influential factors associated with mean beliefs regarding community pharmacy-delivered MBSR for chronic pain management were assessed via multiple linear regression. Of the 302 survey respondents, the majority were white (79.1%) and female (50.7%), with a mean age of 44.65 years. Respondents' self-rated MBSR knowledge (mean [SD] scale score: 2.30 [0.68]) and confidence (2.65 [0.87]) were low, although perceived barriers to access were low overall (2.22 [0.53]). Beliefs regarding the use of MBSR for treatment of chronic pain were positive in general (3.67 [0.71]), but more negative regarding community pharmacy-delivered MBSR (2.38 [0.56]). Confidence in seeking out MBSR (β = 0.297, 95% CI = 0.219 to 0.375; p < 0.001) and current opioid use (β = 0.419, 95% CI = 0.147 to 0.690; p = 0.003) were positively associated with beliefs regarding pharmacy-delivered MBSR, while annual household income (β = -0.124, 95% CI = -0.244 to -0.004; p = 0.043) and level of bodily pain (β = -0.149, 95% CI = -0.291 to -0.008; p = 0.039) exerted statistically significant negative influences. Respondents preferred a hybrid MBSR class format including both online and in-person components (29.7%) as well as both group and individual session options (43.7%). In conclusion, further education is necessary to increase the public's perception of community pharmacies as a resource for complementary and integrative health.

Implementation of Evidence-Based Psychotherapies for Posttraumatic Stress Disorder: A Systematic Review

Guidelines strongly recommend trauma-focused therapies to treat posttraumatic stress disorder. Implementation of cognitive processing therapy (CPT) and prolonged exposure (PE) in Veterans Health Administration (VHA) and non-VHA settings began in 2006. We conducted a systematic review of implementation facilitators and challenges and strategies to address barriers. We searched MEDLINE, Embase, PsycINFO, and CINAHL from inception until March 2021 for English-language articles. Two individuals reviewed eligibility and rated quality. Quantitative results were abstracted by one reviewer and verified by a second. Qualitative results were independently coded by two reviewers and finalized through consensus. We used RE-AIM and CFIR frameworks to synthesize findings. 29 eligible studies addressed CPT/PE, mostly conducted in VHA. Training/education with audit/feedback was the primary implementation strategy and was linked to improved provider CPT/PE perceptions and self-efficacy. Use was not widespread. Only six studies tested other implementation strategies with mixed impact. Following VHA implementation, strong support for training, perceived effectiveness for patients and benefits for clinics, and positive patient experiences and relationships with providers were reported. However, barriers persisted including perceived protocol inflexibility, complex referral processes and patient complexity and competing needs. In non-VHA settings, providers perceived fewer barriers, but few were CPT/PE trained. Across both settings, fewer studies targeted patient factors. Training/education with audit/feedback improved perceptions and the availability of CPT/PE, but not consistent use. Studies testing implementation strategies to address post-training challenges, including patient-level factors, are needed. A few studies are underway in VHA to test patient-focused and other implementation strategies. Research assessing actual vs perceived barriers in non-VHA settings is needed to elucidate unique challenges experienced.

Barriers and facilitators of evidence-based psychotherapies for chronic pain in adults: A systematic review

Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) have demonstrated effectiveness for improving outcomes in chronic pain. These evidence-based psychotherapies (EBPs) remain underutilized in clinical practice, however. To identify research gaps and next steps for improving uptake of EBPs, we conducted a systematic review of patient-, provider-, and system-level barriers and facilitators of their use for chronic pain. We searched MEDLINE, Embase, PsycINFO, and CINAHL databases databases from inception through September 2022. Prespecified eligibility criteria included outpatient treatment of adults with chronic pain; examination of barriers and facilitators and/or evaluation of implementation strategies; conducted in the United States (US), United Kingdom (UK), Ireland, Canada or Australia; and publication in English. Two reviewers independently assessed eligibility and rated quality. We conducted a qualitative synthesis of results using a best-fit framework approach building upon domains of the Consolidated Framework for Implementation Research (CFIR). We identified 34 eligible studies (33 moderate or high quality), most (n=28) of which addressed patient-level factors. Shared barriers across EBPs included variable patient buy-in to therapy rationale and competing responsibilities for patients; shared facilitators included positive group or patient-therapist dynamics. Most studies examining ACT and all examining MBSR assessed only group formats. No studies compared barriers, facilitators, or implementation strategies of group CBT to individual CBT, or of telehealth to in-person EBPs. Conceptual mismatches of patient knowledge and beliefs with therapy principles were largely analyzed qualitatively, and studies did not explore how these mismatches were addressed to support engagement. Future research on EBPs for chronic pain in real-world practice settings is needed to explore provider and system-level barriers and facilitators, heterogeneity of effects and uptake, and both effects and uptake of EBPs delivered in various formats, including group vs. individual therapy and telehealth or asynchronous digital approaches. Perspective This systematic review synthesizes evidence on barriers and facilitators to uptake of cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness-based stress reduction for chronic pain. Findings can guide future implementation work to increase availability and use of evidence-based psychotherapies for treatment of chronic pain. Registration: PROSPERO number CRD42021252038.

Overall and Differential Attrition in Mindfulness-Based Interventions: A Meta-Analysis

Objectives

Attrition is very common in longitudinal research, including randomized controlled trials (RCTs) testing psychological interventions. Establishing rates and predictors of attrition in mindfulness-based interventions (MBIs) can assist clinical trialists and intervention developers. Differential attrition in RCTs that compared MBIs with structure and intensity matched active control conditions also provides an objective metric of relative treatment acceptability.

Methods

We aimed to evaluate rates and predictors of overall and differential attrition in RCTs of MBIs compared with matched active control conditions. Attrition was operationalized as loss to follow-up at post-test. Six online databases were searched.

Results

Across 114 studies (n = 11,288), weighted mean attrition rate was 19.1% (95% CI [.16, .22]) in MBIs and 18.6% ([.16, .21]) in control conditions. In the primary model, no significant difference was found in attrition between MBIs and controls (i.e., differential attrition; odds ratio [OR] = 1.05, [0.92, 1.19]). However, in sensitivity analyses with trim-and-fill adjustment, without outliers, and when using different estimation methods (Peto and Mantel-Haenszel), MBIs yielded slightly higher attrition (ORs = 1.10 to 1.25, ps < .050). Despite testing numerous moderators of overall and differential attrition, very few significant predictors emerged.

Conclusions

Results support efforts to increase the acceptability of MBIs, active controls, and/or RCTs, and highlight the possibility that for some individuals, MBIs may be less acceptable than alternative interventions. Further research including individual patient data meta-analysis is warranted to identify predictors of attrition and to characterize instances where MBIs may or may not be recommended.

Impact of a Mindfulness-Based Stress Reduction Program on Psychological Well-Being, Cortisol, and Inflammation in Women Veterans

BACKGROUND

Women veterans experience higher levels of stress-related symptoms than their civilian counterparts. Psychological stress is associated with greater inflammation and may increase risk for cardiovascular disease (CVD). Mindfulness-based stress reduction (MBSR) has been found to improve psychological well-being in other populations but no randomized controlled trials (RCT) have been conducted examining the impact of MBSR on well-being and inflammation in women veterans at risk for CVD.

OBJECTIVE

Determine the effectiveness of MBSR in improving psychological well-being, cortisol, and inflammation associated with CVD in women veterans.

DESIGN

The design is a RCT comparing MBSR to an active control condition (ACC) consisting of a health education program.

PARTICIPANTS

Women veterans (N=164) with risk factors for CVD from the Chicagoland area participated in the study.

INTERVENTION

An 8-week MBSR program with weekly 2.5-h classes was compared to an ACC consisting of an 8-week health promotion education program with weekly 2.5-h classes.

MAIN MEASURES

The outcomes were psychological well-being [perceived stress, depressive symptoms, loneliness, and post-traumatic stress disorder (PTSD)] symptoms and stress-related markers, including diurnal salivary cortisol and cytokines interleukin-6 (IL-6) and interferon gamma (IFN-γ). Data were collected at baseline, 4 weeks (mid-point of intervention), 8 weeks (completion of intervention), and 6 months after completion of MBSR or ACC.

KEY RESULTS

Compared to the ACC, women who participated in MBSR reported less perceived stress, loneliness, and symptoms of PTSD. Although there were no significant differences between groups or changes over time in IL-6 or IFN-γ, participants in the MBSR program demonstrated a more rapid decline in diurnal salivary cortisol as compared to those in the ACC.

CONCLUSIONS

MBSR was found to improve psychological well-being and decrease diurnal salivary cortisol in women veterans at risk for CVD. Health care providers may consider MBSR for women veterans as a means by which to improve their psychological well-being.

Effects of an integrated mindfulness intervention for veterans with diabetes distress: a randomized controlled trial

INTRODUCTION

US military veterans have disproportionately high rates of diabetes and diabetes-related morbidity in addition to being at risk of comorbid stress-related conditions. This study aimed to examine the effects of a technology-supported mindfulness intervention integrated into usual diabetes care and education on psychological and biobehavioral outcomes.

RESEARCH DESIGN AND METHODS

Veterans (N=132) with type 1 or 2 diabetes participated in this two-arm randomized controlled efficacy trial. The intervention arm received a one-session mindfulness intervention integrated into a pre-existing program of diabetes self-management education and support (DSMES) plus one booster session and 24 weeks of home practice supported by a mobile application. The control arm received one 3-hour comprehensive DSMES group session. The primary outcome was change in diabetes distress (DD). The secondary outcomes were diabetes self-care behaviors, diabetes self-efficacy, post-traumatic stress disorder (PTSD), depression, mindfulness, hemoglobin A1C (HbA1C), body weight, and blood pressure. Assessments were conducted at baseline, 12 weeks, and 24 weeks. Participant satisfaction and engagement in home practice were assessed in the intervention group at 12 and 24 weeks.

RESULTS

Intention-to-treat group by time analyses showed a statistically significant improvement in DD in both arms without significant intervention effect from baseline to 24 weeks. Examination of distal effects on DD between weeks 12 and 24 showed significantly greater improvement in the intervention arm. Improvement in DD was greater when baseline HbA1C was <8.5%. A significant intervention effect was also shown for general dietary behaviors. The secondary outcomes diabetes self-efficacy, PTSD, depression, and HbA1C significantly improved in both arms without significant intervention effects. Mindfulness and body weight were unchanged in either group.

CONCLUSIONS

A technology-supported mindfulness intervention integrated with DSMES showed stronger distal effects on DD compared with DSMES control. Examination of longer-term outcomes, underlying mechanisms, and the feasibility of virtual delivery is warranted.

Care Outcomes for Chiropractic Outpatient Veterans (COCOV): a qualitative study with veteran stakeholders from a pilot trial of multimodal chiropractic care

BACKGROUND

Low back pain (LBP) is common among military veterans seeking treatment in Department of Veterans Affairs (VA) healthcare facilities. As chiropractic services within VA expand, well-designed pragmatic trials and implementation studies are needed to assess clinical effectiveness and program uptake. This study evaluated veteran stakeholder perceptions of the feasibility and acceptability of care delivery and research processes in a pilot trial of multimodal chiropractic care for chronic LBP.

METHODS

The qualitative study was completed within a mixed-method, single-arm, pragmatic, pilot clinical trial of chiropractic care for LBP conducted in VA chiropractic clinics. Study coordinators completed semi-structured, in person or telephone interviews with veterans near the end of the 10-week trial. Interviews were audiorecorded and transcribed verbatim. Qualitative content analysis using a directed approach explored salient themes related to trial implementation and delivery of chiropractic services.

RESULTS

Of 40 participants, 24 completed interviews (60% response; 67% male gender; mean age 51.7 years). Overall, participants considered the trial protocol and procedures feasible and reported that the chiropractic care and recruitment methods were acceptable. Findings were organized into 4 domains, 10 themes, and 21 subthemes. Chiropractic service delivery domain encompassed 3 themes/8 subthemes: scheduling process (limited clinic hours, scheduling future appointments, attendance barriers); treatment frequency (treatment sufficient for LBP complaint, more/less frequent treatments); and chiropractic clinic considerations (hire more chiropractors, including female chiropractors; chiropractic clinic environment; patient-centered treatment visits). Outcome measures domain comprised 3 themes/4 subthemes: questionnaire burden (low burden vs. time-consuming or repetitive); relevance (items relevant for LBP study); and timing and individualization of measures (questionnaire timing relative to symptoms, personalized approach to outcomes measures). The online data collection domain included 2 themes/4 subthemes: user concerns (little difficulty vs. form challenges, required computer skills); and technology issues (computer/internet access, junk mail). Clinical trial planning domain included 2 themes/5 subthemes: participant recruitment (altruistic service by veterans, awareness of chiropractic availability, financial compensation); and communication methods (preferences, potential barriers).

CONCLUSIONS

This qualitative study highlighted veteran stakeholders' perceptions of VA-based chiropractic services and offered important suggestions for conducting a full-scale, veteran-focused, randomized trial of multimodal chiropractic care for chronic LBP in this clinical setting.

Theory of Planned Behavior and Mindfulness Intentions in Chronic Low Back Pain

Objectives

Theory of planned of behavior (TPB) constructs have been linked to health behavior intentions. Intentions to try mindfulness-based stress reduction (MBSR), a first-line therapy for chronic low back pain (cLBP), have been less studied. This study aimed to identify which TPB constructs could inform strategies to improve adoption of MBSR.

Methods

People with cLBP (n = 457) read a description of MBSR then completed survey items assessing TPB constructs: attitudes, norms, self-efficacy, perceived control, and intentions to try MBSR training.

Results

Structural equation modeling showed self-efficacy/control (coefficient: 0.564), norms (0.245), and attitudes (0.131) were all positively associated with intentions to try mindfulness trainings.

Conclusions

Results suggest self-efficacy/control may be the most strongly related TPB construct with intentions to try MBSR. Dissemination of MBSR for cLBP could focus on adapting the intervention to increase accessibility and improving available resources to overcome logistical barriers (online formats, drop-in classes).

Learning to Apply Mindfulness to Pain (LAMP): Design for a Pragmatic Clinical Trial of Two Mindfulness-Based Interventions for Chronic Pain

BACKGROUND

Mindfulness-based interventions (MBIs) are evidence-based nonpharmacological treatments for treating chronic pain. However, the predominant MBI, mindfulness-based stress reduction, has features that pose significant implementation barriers.

OBJECTIVES

This study will test two approaches to delivering MBIs for improving Veterans' chronic pain and mental health comorbidities. These two approaches address key implementation barriers.

METHODS

We will conduct a four-site, three-arm pragmatic randomized controlled trial, Learning to Apply Mindfulness to Pain (LAMP), to test the effectiveness of two MBIs at improving pain and mental health comorbidities. Mobile+Group LAMP consists of prerecorded modules presented by a mindfulness instructor that are viewed in an online group setting and interspersed with discussions led by a facilitator. Mobile LAMP consists of the same prerecorded modules but does not include a group component. We will test whether either of these MBIs will be more effective than usual care at improving chronic pain and whether the Mobile+Group LAMP will be more effective than Mobile LAMP at improving chronic pain. Comparisons for the primary hypotheses will be conducted with continuous outcomes (Brief Pain Inventory interference score) repeated at 10 weeks, 6 months, and 12 months. The secondary hypotheses are that Mobile+Group LAMP and Mobile LAMP will be more effective than usual care at improving secondary outcomes (e.g., post-traumatic stress disorder, depression). We will also confirm the comparisons for the primary and secondary hypotheses in gender-specific strata.

IMPLICATIONS

This trial is expected to result in two approaches for delivering MBIs that will optimize engagement, adherence, and sustainability and be able to reach large numbers of Veterans.

Mindfulness-based interventions for military veterans: A systematic review and analysis of the literature

BACKGROUND

In recent years, mindfulness-based interventions (MBIs) have experienced exponential growth in terms of development, application, and research. However, few studies have examined implementation and efficacy of these interventions in particular populations, such as military Veterans. Such studies are needed as one cannot assume that the literature on MBIs implemented with the general population or other specific populations apply equally well to Veterans. This population is unique regarding professional competencies, military ethos, high degrees of medical comorbidities and barriers to treatment. The aim of this work was to review and summarize the literature over the previous five years (2014-2020) assessing the use of MBIs among military Veterans to guide clinical care and future research.

METHODS

Systematic literature review.

RESULTS

A total of 88 articles were found. Screening titles and abstracts resulted in 49 articles being excluded. The remaining 39 articles were read in full, and of these, 12 were excluded due to not fully meeting the inclusion criteria. Thus, the present review included a total of 27 articles, 3 of which used qualitative methods and 24 of which used quantitative methods.

CONCLUSIONS

MBIs hold promise as complementary adjunctive interventions for Veterans with PTSD and possibly other psychiatric disorders. Currently there are significant gaps in the literature that must be addressed to move the field forward. The main deficiency is, with a few exceptions, the lack of rigorous RCTs. Another major concern is the lack of generalizability to female and non-white Veterans given that the subject samples across all studies reviewed were 85% male and 76% white. At this time, MBSR, PCBMT and MBCT can be recommended as adjunctive complementary interventions for the reduction of PTSD symptoms. Research recommendations to move the field forward are provided.

Efficacy and acceptability of mindfulness-based interventions for military veterans: A systematic review and meta-analysis

BACKGROUND

Military veterans report high rates of psychiatric and physical health symptoms that may be amenable to mindfulness-based interventions (MBIs). Inconsistent prior findings and questions of fit between MBIs and military culture highlight the need for a systematic evaluation of this literature.

OBJECTIVE

To quantify the efficacy and acceptability of MBIs for military veterans.

DATA SOURCES

We searched five databases (MEDLINE/PubMed, CINAHL, Scopus, Web of Science, PsycINFO) from inception to October 16th, 2019.

STUDY SELECTION

Randomized controlled trials (RCTs) testing MBIs in military veterans.

RESULTS

Twenty studies (k = 16 unique comparisons, N = 898) were included. At post-treatment, MBIs were superior to non-specific controls (e.g., waitlist, attentional placebos) on measures of posttraumatic stress disorder (PTSD), depression, general psychological symptoms (i.e., aggregated across symptom domains), quality of life / functioning, and mindfulness (Hedges' gs = 0.32 to 0.80), but not physical health. At follow-up (mean length = 3.19 months), MBIs continued to outperform non-specific controls on general psychological symptoms, but not PTSD. MBIs were superior to specific active controls (i.e., other therapies) at post-treatment on measures of PTSD and general psychological symptoms (gs = 0.19 to 0.25). Participants randomized to MBIs showed higher rates of attrition than those randomized to control interventions (odds ratio = 1.98). Several models were not robust to tests of publication bias. Study quality and risk of bias assessment indicated several areas of concern.

CONCLUSIONS

MBIs may improve psychological symptoms and quality of life / functioning in veterans. Questionable acceptability and few high-quality studies support the need for rigorous RCTs, potentially adapted to veterans.

Interventions for adults with a history of complex traumatic events: the INCiTE mixed-methods systematic review

BACKGROUND

People with a history of complex traumatic events typically experience trauma and stressor disorders and additional mental comorbidities. It is not known if existing evidence-based treatments are effective and acceptable for this group of people.

OBJECTIVE

To identify candidate psychological and non-pharmacological treatments for future research.

DESIGN

Mixed-methods systematic review.

PARTICIPANTS

Adults aged ≥ 18 years with a history of complex traumatic events.

INTERVENTIONS

Psychological interventions versus control or active control; pharmacological interventions versus placebo.

MAIN OUTCOME MEASURES

Post-traumatic stress disorder symptoms, common mental health problems and attrition.

DATA SOURCES

Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 onwards); Cochrane Central Register of Controlled Trials (CENTRAL) (from inception); EMBASE (1974 to 2017 week 16); International Pharmaceutical Abstracts (1970 onwards); MEDLINE and MEDLINE Epub Ahead of Print and In-Process & Other Non-Indexed Citations (1946 to present); Published International Literature on Traumatic Stress (PILOTS) (1987 onwards); PsycINFO (1806 to April week 2 2017); and Science Citation Index (1900 onwards). Searches were conducted between April and August 2017.

REVIEW METHODS

Eligible studies were singly screened and disagreements were resolved at consensus meetings. The risk of bias was assessed using the Cochrane risk-of-bias tool and a bespoke version of a quality appraisal checklist used by the National Institute for Health and Care Excellence. A meta-analysis was conducted across all populations for each intervention category and for population subgroups. Moderators of effectiveness were assessed using metaregression and a component network meta-analysis. A qualitative synthesis was undertaken to summarise the acceptability of interventions with the relevance of findings assessed by the GRADE-CERQual checklist.

RESULTS

One hundred and four randomised controlled trials and nine non-randomised controlled trials were included. For the qualitative acceptability review, 4324 records were identified and nine studies were included. The population subgroups were veterans, childhood sexual abuse victims, war affected, refugees and domestic violence victims. Psychological interventions were superior to the control post treatment for reducing post-traumatic stress disorder symptoms (standardised mean difference -0.90, 95% confidence interval -1.14 to -0.66; number of trials = 39) and also for associated symptoms of depression, but not anxiety. Trauma-focused therapies were the most effective interventions across all populations for post-traumatic stress disorder and depression. Multicomponent and trauma-focused interventions were effective for negative self-concept. Phase-based approaches were also superior to the control for post-traumatic stress disorder and depression and showed the most benefit for managing emotional dysregulation and interpersonal problems. Only antipsychotic medication was effective for reducing post-traumatic stress disorder symptoms; medications were not effective for mental comorbidities. Eight qualitative studies were included. Interventions were more acceptable if service users could identify benefits and if they were delivered in ways that accommodated their personal and social needs.

LIMITATIONS

Assessments about long-term effectiveness of interventions were not possible. Studies that included outcomes related to comorbid psychiatric states, such as borderline personality disorder, and populations from prisons and humanitarian crises were under-represented.

CONCLUSIONS

Evidence-based psychological interventions are effective and acceptable post treatment for reducing post-traumatic stress disorder symptoms and depression and anxiety in people with complex trauma. These interventions were less effective in veterans and had less of an impact on symptoms associated with complex post-traumatic stress disorder.

FUTURE WORK

Definitive trials of phase-based versus non-phase-based interventions with long-term follow-up for post-traumatic stress disorder and associated mental comorbidities.

Veterans' interests, perceptions, and use of mindfulness

Objective:

Mindfulness-based interventions are an evidence-based approach utilized in health care. There is developing evidence for effective use with military Veterans. However, little is known about Veterans’ view of mindfulness. This study aims to understand their interests, perceptions, and use of mindfulness to enhance educational outreach and treatment engagement.

Methods:

A cross-sectional study was conducted across the Veterans Health Administration in Salt Lake City, UT by administering a questionnaire to military Veterans. The questionnaire included the following themes: (1) demographics and respondents’ mindfulness practice; (2) respondents’ perceptions and beliefs about mindfulness; and (3) respondents’ knowledge and interest in learning about mindfulness.

Results:

In all, 185 military Veterans were surveyed; 30% practiced mindfulness in the past year, mainly for stress, posttraumatic stress disorder, sleep, and depression. Over 75% who practiced reported perceived benefit. Veterans rarely reported negative beliefs about mindfulness; 56% perceived an understanding of mindfulness and 46% were aware of Veterans Health Administration mindfulness offerings. In all, 55% were interested in learning about mindfulness, 58% were interested in learning how it could help, and 43% were interested in combining mindfulness with a pleasurable activity.

Conclusion:

Educational engagement approaches should be directed toward the benefits of mindfulness practice with minimal need to address negative beliefs. Outreach including education, with an experiential component, about mindfulness classes, availability of evening and weekend classes, individual sessions, and virtual offerings into Veteran’s homes, may enhance engagement in mindfulness-based interventions. Mindfulness-based interventions that combine mindfulness training with an experiential pleasurable activity may be one mechanism to enhance treatment engagement.

Psychological and pharmacological interventions for posttraumatic stress disorder and comorbid mental health problems following complex traumatic events: Systematic review and component network meta-analysis

BACKGROUND

Complex traumatic events associated with armed conflict, forcible displacement, childhood sexual abuse, and domestic violence are increasingly prevalent. People exposed to complex traumatic events are at risk of not only posttraumatic stress disorder (PTSD) but also other mental health comorbidities. Whereas evidence-based psychological and pharmacological treatments are effective for single-event PTSD, it is not known if people who have experienced complex traumatic events can benefit and tolerate these commonly available treatments. Furthermore, it is not known which components of psychological interventions are most effective for managing PTSD in this population. We performed a systematic review and component network meta-analysis to assess the effectiveness of psychological and pharmacological interventions for managing mental health problems in people exposed to complex traumatic events.

METHODS AND FINDINGS

We searched CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, International Pharmaceutical Abstracts, MEDLINE, Published International Literature on Traumatic Stress, PsycINFO, and Science Citation Index for randomised controlled trials (RCTs) and non-RCTs of psychological and pharmacological treatments for PTSD symptoms in people exposed to complex traumatic events, published up to 25 October 2019. We adopted a nondiagnostic approach and included studies of adults who have experienced complex trauma. Complex-trauma subgroups included veterans; childhood sexual abuse; war-affected; refugees; and domestic violence. The primary outcome was reduction in PTSD symptoms. Secondary outcomes were depressive and anxiety symptoms, quality of life, sleep quality, and positive and negative affect. We included 116 studies, of which 50 were conducted in hospital settings, 24 were delivered in community settings, seven were delivered in military clinics for veterans or active military personnel, five were conducted in refugee camps, four used remote delivery via web-based or telephone platforms, four were conducted in specialist trauma clinics, two were delivered in home settings, and two were delivered in primary care clinics; clinical setting was not reported in 17 studies. Ninety-four RCTs, for a total of 6,158 participants, were included in meta-analyses across the primary and secondary outcomes; 18 RCTs for a total of 933 participants were included in the component network meta-analysis. The mean age of participants in the included RCTs was 42.6 ± 9.3 years, and 42% were male. Nine non-RCTs were included. The mean age of participants in the non-RCTs was 40.6 ± 9.4 years, and 47% were male. The average length of follow-up across all included studies at posttreatment for the primary outcome was 11.5 weeks. The pairwise meta-analysis showed that psychological interventions reduce PTSD symptoms more than inactive control (k = 46; n = 3,389; standardised mean difference [SMD] = -0.82, 95% confidence interval [CI] -1.02 to -0.63) and active control (k-9; n = 662; SMD = -0.35, 95% CI -0.56 to -0.14) at posttreatment and also compared with inactive control at 6-month follow-up (k = 10; n = 738; SMD = -0.45, 95% CI -0.82 to -0.08). Psychological interventions reduced depressive symptoms (k = 31; n = 2,075; SMD = -0.87, 95% CI -1.11 to -0.63; I2 = 82.7%, p = 0.000) and anxiety (k = 15; n = 1,395; SMD = -1.03, 95% CI -1.44 to -0.61; p = 0.000) at posttreatment compared with inactive control. Sleep quality was significantly improved at posttreatment by psychological interventions compared with inactive control (k = 3; n = 111; SMD = -1.00, 95% CI -1.49 to -0.51; p = 0.245). There were no significant differences between psychological interventions and inactive control group at posttreatment for quality of life (k = 6; n = 401; SMD = 0.33, 95% CI -0.01 to 0.66; p = 0.021). Antipsychotic medicine (k = 5; n = 364; SMD = -0.45; -0.85 to -0.05; p = 0.085) and prazosin (k = 3; n = 110; SMD = -0.52; -1.03 to -0.02; p = 0.182) were effective in reducing PTSD symptoms. Phase-based psychological interventions that included skills-based strategies along with trauma-focused strategies were the most promising interventions for emotional dysregulation and interpersonal problems. Compared with pharmacological interventions, we observed that psychological interventions were associated with greater reductions in PTSD and depression symptoms and improved sleep quality. Sensitivity analysis showed that psychological interventions were acceptable with lower dropout, even in studies rated at low risk of attrition bias. Trauma-focused psychological interventions were superior to non-trauma-focused interventions across trauma subgroups for PTSD symptoms, but effects among veterans and war-affected populations were significantly reduced. The network meta-analysis showed that multicomponent interventions that included cognitive restructuring and imaginal exposure were the most effective for reducing PTSD symptoms (k = 17; n = 1,077; mean difference = -37.95, 95% CI -60.84 to -15.16). Our use of a non-diagnostic inclusion strategy may have overlooked certain complex-trauma populations with severe and enduring mental health comorbidities. Additionally, the relative contribution of skills-based intervention components was not feasibly evaluated in the network meta-analysis.

CONCLUSIONS

In this systematic review and meta-analysis, we observed that trauma-focused psychological interventions are effective for managing mental health problems and comorbidities in people exposed to complex trauma. Multicomponent interventions, which can include phase-based approaches, were the most effective treatment package for managing PTSD in complex trauma. Establishing optimal ways to deliver multicomponent psychological interventions for people exposed to complex traumatic events is a research and clinical priority.

Tailoring an evidence-based lifestyle intervention to meet the needs of women Veterans with prediabetes

Prediabetes affects one-third of U.S. adults. Lifestyle change interventions, such as the Diabetes Prevention Program (DPP), can significantly lower type 2 diabetes risk, but little is known about how the DPP could be best adapted for women. This mixed-methods study assessed the impact of gender-tailoring and modality choice on DPP engagement among women Veterans with prediabetes. Participants were offered women-only groups and either in-person/peer-led or online modalities. Implementation outcomes were assessed using attendance logs, recruitment calls, and semi-structured interviews about patient preferences. Between June 2016 and March 2017, 119 women Veterans enrolled in the DPP (n = 51 in-person, n = 68 online). We conducted 22 interviews between August and September 2016 (n = 10 early-implementation) and March and July 2017 (n = 12 follow-up). Most interviewees preferred women-only groups, citing increased comfort, camaraderie, and mutual understanding of gender-specific barriers to lifestyle change. More women preferred online DPP, and those using this modality participated at higher rates. Most endorsed the importance of modality choice and were satisfied with their selection; however, selection was frequently based on participants' personal circumstances and access barriers and not on a "preferred choice" of two equally accessible options. Patient engagement and program reach can be expanded by tailoring the DPP for population-specific needs.

Differential impact of mindfulness practices on aggression among law enforcement officers

Objectives

Home-based mindfulness practice is a common component of formal mindfulness training (MT) protocols. Obtaining objective data from home-based mindfulness practice is challenging. Interpreting associations between home-based mindfulness practice and clinically impactful outcomes is complicated given the variability in recommendations in length, frequency, and type of practice. In this exploratory study, adherence to home-based practices of Mindfulness-Based Resilience Training (MBRT) was studied in order to evaluate associations with clinical outcomes.

Methods

Home practices from 24 (92% male, non-Hispanic white, aged M = 43.20 years) law enforcement officers (LEOs) from the urban Pacific Northwest enrolled in a feasibility and efficacy trial of MBRT were studied using an objective tracking device and self-report data. Outcomes included adherence to home-based mindfulness practices and self-reported aggression.

Results

Participants completed 59.12% of the frequency amount of practice assigned in the MBRT curriculum. Frequency of practice was associated with decreased aggression, adjusted R ² = .41, F(3,23) = 6.14, p = .004. Duration of practice also predicted decreased aggression, adjusted R ² = .33, F(3,23) = 4.76, p = .011.

Conclusions

Home-based MBRT practices for LEOs, even at low rates of adherence, may reduce aggression. MTs may show beneficial effects for other populations presented with challenges to engage in regular MT practices.

Prevalence of Mental Health Problems and Willingness to Participate in a Mindfulness Treatment: An Examination among Veterans Injured in Combat

Numerous studies have demonstrated that combat-exposed military veterans are at risk for numerous psychiatric disorders and rates of comorbid mental health and substance use disorders are high. Veterans wounded in combat are a particularly high-risk group of military veterans, however treatment services are often underutilized among this group and it is unclear whether an online treatment program that targets emotional and physical distress (including mental health symptoms and substance use disorders) would be appealing to Veterans wounded in combat. The goal of the current study was to conduct formative research on whether veterans wounded in combat would be interested in an online mindfulness-based treatment to help them cope with emotional and physical discomfort. We recruited Veterans from Combat Wounded Coalition (n = 163; 74.2% non-Hispanic White; 95.7% male) to complete an online survey of mental health and substance use disorder symptoms and willingness to participate in mindfulness treatment. The majority of participants reported significant mental health symptoms and indicated that they would be willing to participate in mindfulness treatment, either at the VA (54.0%) or online (59.5%). Those with problems in multiple health domains and lower self-compassion were significantly more likely to express interest in treatment and likely to represent a very high need group of veterans. The development of a mindfulness-based treatment for this group of individuals could be very helpful in reducing mental health symptoms and improving quality of life among wounded warriors.

Mindfulness-based resilience training to reduce health risk, stress reactivity, and aggression among law enforcement officers: A feasibility and preliminary efficacy trial

The primary objective of this study was to assess feasibility and gather preliminary outcome data on Mindfulness-Based Resilience Training (MBRT) for law enforcement officers. Participants (n = 61) were randomized to either an 8-week MBRT course or a no intervention control group. Self-report and physiological data were collected at baseline, post-training, and three months following intervention completion. Attendance, adherence, post-training participant feedback, and interventionist fidelity to protocol all demonstrated feasibility of MBRT for law enforcement officers. Compared to no intervention controls, MBRT participants experienced greater reductions in salivary cortisol, self-reported aggression, organizational stress, burnout, sleep disturbance, and reported increases in psychological flexibility and non-reactivity at post-training; however, group differences were not maintained at three-month follow-up. This initial randomized trial suggests MBRT is a feasible intervention. Outcome data suggest MBRT targets key physiological, psychological, and health risk factors in law enforcement officers, consistent with the potential to improve officer health and public safety. However, follow-up training or "booster" sessions may be needed to maintain training gains. A fully powered longitudinal randomized trial is warranted.

An Exploration of Formal and Informal Mindfulness Practice and Associations with Wellbeing

Mindfulness has transdiagnostic applicability, but little is known about how people first begin to practice mindfulness and what sustains practice in the long term. The aim of the present research was to explore the experiences of a large sample of people practicing mindfulness, including difficulties with practice and associations between formal and informal mindfulness practice and wellbeing. In this cross-sectional study, 218 participants who were practicing mindfulness or had practiced in the past completed an online survey about how they first began to practice mindfulness, difficulties and supportive factors for continuing to practice, current wellbeing, and psychological flexibility. Participants had practiced mindfulness from under a year up to 43 years. There was no significant difference in the frequency of formal mindfulness practice between those who had attended a face-to-face taught course and those who had not. Common difficulties included finding time to practice formally and falling asleep during formal practice. Content analysis revealed “practical resources,” “time/routine,” “support from others,” and “attitudes and beliefs,” which were supportive factors for maintaining mindfulness practice. Informal mindfulness practice was related to positive wellbeing and psychological flexibility. Frequency (but not duration) of formal mindfulness practice was associated with positive wellbeing; however, neither frequency nor duration of formal mindfulness practice was significantly associated with psychological flexibility. Mindfulness teachers will be able to use the present findings to further support their students by reminding them of the benefits as well as normalising some of the challenges of mindfulness practice including falling asleep.

Mindfulness-Based Processes of Healing for Veterans with Post-Traumatic Stress Disorder

OBJECTIVE

U.S. veterans are at increased risk of developing post-traumatic stress disorder (PTSD). Prior studies suggest a benefit of mindfulness-based stress reduction (MBSR) for PTSD, but the mechanisms through which MBSR reduces PTSD symptoms and improves functional status have received limited empirical inquiry. This study used a qualitative approach to better understand how training in mindfulness affects veterans with PTSD.

DESIGN

Qualitative study using semistructured in-depth interviews following participation in an MBSR intervention.

SETTING

Outpatient.

INTERVENTION

Eight-week MBSR program.

OUTCOME MEASURE

Participants' narratives of their experiences from participation in the program.

RESULTS

Interviews were completed with 15 veterans. Analyses identified six core aspects of participants' MBSR experience related to PTSD: dealing with the past, staying in the present, acceptance of adversity, breathing through stress, relaxation, and openness to self and others. Participants described specific aspects of a holistic mindfulness experience, which appeared to activate introspection and curiosity about their PTSD symptoms. Veterans with PTSD described a number of pathways by which mindfulness practice may help to ameliorate PTSD.

CONCLUSIONS

MBSR holds promise as a nontrauma-focused approach to help veterans with PTSD.

An Evidence Map of the Women Veterans' Health Research Literature (2008-2015)

BACKGROUND

Women comprise a growing proportion of Veterans seeking care at Veterans Affairs (VA) healthcare facilities. VA initiatives have accelerated changes in services for female Veterans, yet the corresponding literature has not been systematically reviewed since 2008. In 2015, VA Women's Health Services and the VA Women's Health Research Network requested an updated literature review to facilitate policy and research planning.

METHODS

The Minneapolis VA Evidence-based Synthesis Program performed a systematic search of research related to female Veterans' health published from 2008 through 2015. We extracted study characteristics including healthcare topic, design, sample size and proportion female, research setting, and funding source. We created an evidence map by organizing and presenting results within and across healthcare topics, and describing patterns, strengths, and gaps.

RESULTS

We identified 2276 abstracts and assessed each for relevance. We excluded 1092 abstracts and reviewed 1184 full-text articles; 750 were excluded. Of 440 included articles, 208 (47%) were related to mental health, particularly post-traumatic stress disorder (71 articles), military sexual trauma (37 articles), and substance abuse (20 articles). The number of articles addressing VA priority topic areas increased over time, including reproductive health, healthcare organization and delivery, access and utilization, and post-deployment health. Three or fewer articles addressed each of the common chronic diseases: diabetes, hypertension, depression, or anxiety. Nearly 400 articles (90%) used an observational design. Eight articles (2%) described randomized trials.

CONCLUSIONS

Our evidence map summarizes patterns, progress, and growth in the female Veterans' health and healthcare literature. Observational studies in mental health make up the majority of research. A focus on primary care delivery over clinical topics in primary care and a lack of sex-specific results for studies that include men and women have contributed to research gaps in addressing common chronic diseases. Interventional research using randomized trials is needed.

A Qualitative Study of Mindfulness Among Veterans With Posttraumatic Stress Disorder: Practices Differentially Affect Symptoms, Aspects of Well-Being, and Potential Mechanisms of Action

This qualitative study explored and compared the subjective experiences of 102 veterans with posttraumatic stress disorder (PTSD) who were randomly assigned to 1 of 4 arms: ( a) body scan, ( b) mindful breathing, ( c) slow breathing, or ( d) sitting quietly. Qualitative data were obtained via semistructured interviews following the intervention and analyzed using conventional content analysis. The percentage of participants within each intervention who endorsed a specific theme was calculated. Two-proportion z tests were then calculated to determine if the differences among themes endorsed in specific groups were statistically significant. Six core themes emerged from analysis of participant responses across the 4 groups: ( a) enhanced present moment awareness, ( b) increased nonreactivity, ( c) increased nonjudgmental acceptance, ( d) decreased physiological arousal and stress reactivity, ( e) increased active coping skills, and ( f) greater relaxation. More participants in the mindfulness intervention groups reported improvement in PTSD symptoms when compared to participants in non-mindfulness groups. Different types of intervention targeted different symptoms and aspects of well-being. Furthermore, type of intervention may have also differentially targeted potential mechanisms of action. This article highlights the importance of employing both quantitative and qualitative research methods when investigating the dynamic process of mindfulness and may inform how practices can be tailored to the needs of the veteran with PTSD.
