Concurrent Validity of the Defense and Veterans Pain Rating Scale in VA Outpatients.

OBJECTIVE: The purpose of this report is to investigate the concurrent validity of the Defense and Veterans Pain Rating Scale (DVPRS) with other validated self-report measures in U.S. veterans. DESIGN: This correlational study was conducted using two samples of outpatients at the Washington, DC Veterans Affairs Medical Center who completed self-report measures relevant to pain conditions, including pain disability, quality of life, and mental health. Study 1 and 2 consisted of n = 204 and n = 13 participants, respectively. METHODS: Bivariate Spearman correlations were calculated to examine the correlation among total scores and subscale scores for each scale of interest. Multiple linear regressions were also computed in Study 1. RESULTS: In Study 1, the DVPRS interference scale (DVPRS-II) was significantly correlated with the Pain Disability Questionnaire (PDQ) (ρ = 0.69, P < 0.001) and the Veterans RAND 36-item Health Survey physical and mental component scales (ρ = -0.37, P < 0.001; ρ = -0.46, P < 0.001, respectively). When controlling for sex, age, and other self-report measures, the relationship between the DVPRS-II and PDQ remained significant. In Study 2, pain interference on the DVPRS and Brief Pain Inventory were highly correlated (ρ = 0.90, P < 0.001); however, the intensity scale of each measure was also highly associated with the interference summary scores. CONCLUSIONS: These findings provide preliminary evidence for the concurrent validity of the DVPRS as a brief, multidimensional measure of pain interference that make it a practical tool for use in primary care settings to assess the impact of pain on daily functioning and monitor chronic pain over time.

CAM utilization among OEF/OIF veterans: findings from the National Health Study for a New Generation of US Veterans.

BACKGROUND: Complementary and alternative medicine (CAM) is increasingly seen as an adjunct to traditional plans of care. This study utilized a representative sample of Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans and OEF/OIF-era veterans to explore the prevalence and characteristics of CAM users. RESEARCH DESIGN: The National Health Study for a New Generation of US Veterans (NewGen) is a longitudinal health study of a population-based cohort of OEF/OIF (deployed) and OEF/OIF-era (nondeployed) veterans. Data from the 2009-2011 NewGen survey (n=20,563) were analyzed to determine prevalence of CAM use by demographic and military characteristics, the types of CAM modalities used, and where the modalities were sought. Results were weighted to the entire population of OEF/OIF and OEF/OIF-era veterans. RESULTS: There was no statistically significant association between CAM use and deployment. Those who used Department of Veterans Affairs (VA) health care after separation were more likely to be CAM users compared with those who did not use VA care; however, the majority of veterans using CAM are using it outside the VA health care system. Massage was the most prevalent CAM modality followed by chiropractic treatment; males were less likely to use CAM than women. CONCLUSIONS: CAM modalities are being utilized by OEF/OIF veterans for health problems mainly outside the VA. Policymakers should determine appropriate use of these modalities.

Optimizing Performance and Mental Skills With Mindfulness-Based Attention Training: Two Field Studies With Operational Units.

INTRODUCTION: Mental skills such as focusing attention and managing emotions are essential for optimal performance in high-stress occupations. Studies with military samples have demonstrated that mindfulness training (MT) led to improved computer-based cognitive performance. MATERIALS AND METHODS: To examine the impact of MT on operational performance, mental skills, and psychological health, a short-form program, Mindfulness-Based Attention Training (MBAT), was delivered to active duty soldiers as part of two randomized trials. Participants in study 1 (n = 121) and study 2 (n = 77) were randomized to one of three conditions: MT with proctored practice, MT with unproctored practice, or a waitlist control. Weekly 2-hour MBAT sessions were offered to participants in both MT conditions for 4 weeks. Beyond these sessions, participants also engaged in mindfulness practice that was proctored (within the occupational context) or unproctored (left up to the individual) for four subsequent weeks. RESULTS: Overall, the frequency of mindfulness practice was generally associated with better performance and improvements in mental skills. In study 1, those who practiced 3 or more days per week performed better on marksmanship under physical stress and reported fewer attentional lapses, less emotion regulation difficulties, greater mental toughness, and higher self-reported mindfulness compared to those who did not practice. In study 2, the frequency of mindfulness practice was associated with fewer attentional lapses and emotion regulation difficulties. CONCLUSIONS: Consistent with prior findings, results suggest that regular engagement in MT practice may help to optimize operational performance and improve mental skills in military cohorts.

Impact of mindfulness training and yoga on injury and pain-related impairment: a group randomized trial in basic combat training.

Introduction: Service members are at risk for pain-related difficulties in functioning and physical injury. Previous studies suggest that mindfulness training (MT) and yoga may prevent these outcomes. The present study was designed to determine the impact of MT and yoga on the health, pain, and injury of Army trainees completing 10 weeks of basic combat training (BCT). Methods: Platoons (≈40 trainees per platoon) were randomized to MT and yoga or training-as-usual in October to December 2020 at a large installation in the US. Self-reported outcomes were health, pain level, and pain impact on training, sleep, mood, and stress. Objective outcomes were injury-related medical encounters and number of diagnoses. The trial was registered at ClinicalTrials. Gov (NCT05550610). Results: Intervention trainees reported significantly better health (OR = 1.05, 95% CI [1.00, 1.10]) and less impact of pain on training (OR = 0.81, 95% CI [0.74, 0.90]), sleep (OR = 0.88, 95% CI [0.81, 0.95]), mood (OR = 0.86, 95% CI [0.78, 0.96]), and stress (OR = 0.88, 95% CI [0.79, 0.98]). There was no significant difference in injury-related medical encounters (AOR = 0.70, 95% CI [0.48, 1.03]), but intervention trainees had fewer diagnoses (OR = 0.67, 95% CI [0.47, 0.95]) and were 30% less likely to have a first medical encounter at any time during BCT. This difference emerged 3 weeks into BCT. Discussion: A combined MT and yoga intervention resulted in better trainee health. The US Army and other organizations requiring resilience under extreme stress should consider implementing MT and yoga to offset risks to employee health.

Self-reported mindfulness and soldier health following a combat deployment.

OBJECTIVE: Combat exposure has been linked to health-related challenges associated with postcombat adjustment, including mental health symptoms, behavior-related problems, physical pain, and functional impairment. Mindfulness, or acceptance of the present moment without reactivity or judgment, may be associated with better mental health following a combat deployment. This study examined whether self-reported mindfulness predicted soldier health outcomes over the course of the postdeployment period. METHOD: U.S. soldiers (n = 627) were surveyed 4 months after a deployment to Afghanistan (T1) and again 3 months later (T2). Mindfulness was assessed using the nonreactivity to inner experience subscale of the Five-Facet Mindfulness Questionnaire. Hierarchical linear regressions examined how mindfulness (T1) moderated the impact of combat exposure (T1) on outcomes at T2. RESULTS: Controlling for rank, the interaction between combat exposure and mindfulness significantly predicted posttraumatic stress disorder (PTSD) symptoms, depression symptoms, risk-taking behaviors, pain symptoms, and functional impairment. The interaction term explained 1% to 2% of the variance in these health outcomes. Simple slopes analyses revealed that combat exposure was associated with more PTSD symptoms, depression symptoms, risk-taking behaviors, pain symptoms, and functional impairment when soldiers reported low levels of mindfulness. There was no effect for alcohol misuse, sleep difficulties, or aggressive behaviors. CONCLUSIONS: Nonreactivity to inner experience may mitigate the detrimental effects of high-levels of combat exposure on both mental and physical health outcomes. These findings indicate that mindfulness strategies such as nonreactivity may be particularly useful for employees facing potentially traumatic stressors in a high-risk occupational context.
