BACKGROUND:Individuals' beliefs about the etiology of persistent physical symptoms (PPS) are linked to differences in coping style. However, it is unclear which attributions are related to greater expectations for improvement. METHOD AND RESULTS/RESULTS:A cross-sectional regression analysis (N = 262) indicated that Veterans with Gulf War Illness (GWI) who attributed their GWI to behavior, (e.g., diet and exercise), had greater expectations for improvement (p = .001) than those who attributed their GWI to deployment, physical, or psychological causes (p values > .05). CONCLUSIONS:Findings support the possible clinical utility of exploring perceived contributing factors of PPS, which may increase perceptions that improvement of PPS is possible.

OBJECTIVE:Gulf War Illness (GWI) and alcohol use are both major sources of disability among Gulf War Veterans. The goal of this secondary data analysis was to examine associations between risky alcohol use, problem-solving impairment, and disability among Veterans in a randomized clinical trial of problem-solving treatment (PST) for GWI. We examined cross-sectional associations and conducted longitudinal analyses to test if alcohol use moderated treatment outcome of PST. METHODS:Participants were 268 United States military Veterans with GWI randomized to PST or a control intervention. Participants were assessed at four timepoints. Measures included the World Health Organization Disability Assessment Schedule 2.0 (WHO-DAS 2.0), Problem Solving Inventory (PSI), and Alcohol Use Disorders Identification Test-Concise (AUDIT-C). We conducted multivariate regression (cross-sectional) and mixed model analyses (longitudinal) with separate models for WHO-DAS 2.0 and PSI. All models included AUDIT-C and household income. This analysis was pre-registered on the Open Science Framework. RESULTS: = 0.05); worse disability was associated with less risky alcohol use. There was no evidence that risky alcohol use moderated effects of PST on disability or PSI. CONCLUSION/CONCLUSIONS:If replicated, the cross-sectional findings suggest high levels of disability may deter heavy drinking among Veterans with GWI. We did not find evidence that risky alcohol use moderated treatment outcome of PST for GWI. More research is needed to identify moderators of GWI interventions and to understand risky drinking among Veterans with complex health problems.

OBJECTIVE:This study evaluated the factors that led to enrollment in, and satisfaction with, behavioral interventions for Veterans living with Gulf War Illness (GWI). METHODS:One-on-one interviews were conducted pre- and post-intervention with participants randomized to receive either telephone delivered problem-solving treatment (n = 51) or health education (N = 49). A total of 99 Veterans were interviewed pre-intervention and 60 post-intervention. Qualitative data were thematically coded and similarities in themes across the two interventions were examined. RESULTS:Before the study began, participants reported desiring to learn new information about their GWI, learn symptom-management strategies, and support improvements to care for other patients with GWI. After the intervention, Veterans felt positively about both interventions because they built strong therapeutic relationships with providers, their experiences were validated by providers, and they were provided GWI information and symptom-management strategies. Results also suggested that interventions do not have to be designed to meet all of the needs held by patients to be acceptable. A minority of participants described that they did not benefit from the interventions. CONCLUSION:The results suggest that satisfaction with behavioral interventions for GWI is driven by a strong therapeutic relationship, validating patient's experiences with GWI, and the intervention meeting some of the patient's needs, particularly increasing knowledge of GWI and improving symptom management.

BACKGROUND:Pain predominant multisymptom illness (pain-CMI) refers to symptom-based conditions where pain is a primary symptom. There is initial evidence that health coaching may be efficacious in treating pain-CMI because it can be tailored to the veteran's goals and emphasizes long-term behavior change, which may indirectly impact the maintaining factors of pain-CMI (e.g., catastrophizing, poor pain control, and limited activity). This paper describes the study protocol and rationale of a randomized controlled trial that will compare the efficacy of remote-delivered health coaching in reducing disability and pain impairment for veterans with pain-CMI to remote-delivered supportive psychotherapy. METHODS:This randomized controlled trial will consist of two treatment arms: remote-delivered health coaching and remote-delivered supportive psychotherapy, the active control. Each treatment condition will consist of twelve, weekly one-on-one meetings with a study provider. In addition to the baseline assessment, participants will also complete 6-week (mid-treatment), 12-week (post-treatment), and 24-week (follow-up) assessments that consist of questionnaires that can be completed remotely. The primary aims for this study are to determine whether health coaching reduces disability and pain impairment as compared to supportive psychotherapy. We will also examine whether health coaching reduces physical symptoms, catastrophizing, limiting activity, and increasing pain control as compared to supportive psychotherapy. DISCUSSION/CONCLUSIONS:This study will contribute to the existing literature on pain-CMI and report the effectiveness of a novel, remote-delivered behavioral intervention.

Medically unexplained syndromes (MUS), also termed persistent physical symptoms, are both prevalent and disabling. Yet treatments for MUS are marked by high rates of patient dissatisfaction, as well as disagreement between patients and providers on the management of persistent physical symptoms. A better understanding of patient-generated goals could increase collaborative goal setting and promote person-centered care, a critical component of MUS treatment; yet research in this area is lacking. This paper aimed to develop a typology of treatment and life goals among Gulf War veterans with a medically unexplained syndrome (Gulf War Illness). We examined participants' responses to open-ended questions about treatment and life goals using Braun and Clarke's thematic analysis methodology. Results showed that treatment goals could be categorized into four overarching themes: 1) Get better/healthier, 2) Improve quality of life, 3) Improve or seek additional treatment, and 4) Don't know/Don't have any. Life goals were categorized into six overarching themes: 1) Live a fulfilling life, 2) Live a happy life, 3) Live a healthy life, 4) Be productive/financially successful, 5) Manage GWI, and 6) Don't know/Don't have any. Treatment goals were largely focused on getting better/healthier (e.g., improving symptoms), whereas life goals focused on living a fulfilling life. Implications for the treatment of Gulf War Illness and patient-provider communication are discussed. ClinicalTrials.gov Identifier: NCT02161133.

IMPORTANCE/UNASSIGNED:Few evidence-based treatments are available for Gulf War illness (GWI). Behavioral treatments that target factors known to maintain the disability from GWI, such as problem-solving impairment, may be beneficial. Problem-solving treatment (PST) targets problem-solving impairment and is an evidence-based treatment for other conditions. OBJECTIVE/UNASSIGNED:To examine the efficacy of PST to reduce disability, problem-solving impairment, and physical symptoms in GWI. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This multicenter randomized clinical trial conducted in the US Department of Veterans Affairs compared PST with health education in a volunteer sample of 511 Gulf War veterans with GWI and disability (January 1, 2015, to September 1, 2019); outcomes were assessed at 12 weeks and 6 months. Statistical analysis was conducted between January 1, 2019, and December 31, 2020. INTERVENTIONS/UNASSIGNED:Problem-solving treatment taught skills to improve problem-solving. Health education provided didactic health information. Both were delivered by telephone weekly for 12 weeks. MAIN OUTCOMES AND MEASURES/UNASSIGNED:The primary outcome was reduction from baseline to 12 weeks in self-report of disability (World Health Organization Disability Assessment Schedule). Secondary outcomes were reductions in self-report of problem-solving impairment and objective problem-solving. Exploratory outcomes were reductions in pain, pain disability, and fatigue. RESULTS/UNASSIGNED:A total of 268 veterans (mean [SD] age, 52.9 [7.3] years; 88.4% male; 66.8% White) were randomized to PST (n = 135) or health education (n = 133). Most participants completed all 12 sessions of PST (114 of 135 [84.4%]) and health education (120 of 133 [90.2%]). No difference was found between groups in reductions in disability at the end of treatment. Results suggested that PST reduced problem-solving impairment (moderate effect, 0.42; P = .01) and disability at 6 months (moderate effect, 0.39; P = .06) compared with health education. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this randomized clinical trial of the efficacy of PST for GWI, no difference was found between groups in reduction in disability at 12 weeks. Problem-solving treatment had high adherence and reduced problem-solving impairment and potentially reduced disability at 6 months compared with health education. These findings should be confirmed in future studies. TRIAL REGISTRATION/UNASSIGNED:ClinicalTrials.gov Identifier: NCT02161133.

This study describes Veterans Affairs providers' perceived knowledge gaps for addressing COVID-19 concerns among Veterans generally and specifically among Veterans with a history of military exposures. A needs assessment was conducted through an online survey of 2,818 medical and behavioral health care providers. Results highlight the importance of ongoing education, even in topics for which providers endorsed adequate knowledge (eg, handwashing). Results also accentuated the need for educating providers about effectively communicating with patients regarding concerning medical topics when scientific data is scarce. Implications are discussed.

AIMS/OBJECTIVE:We describe a clinical trial which is seeking to determine the effectiveness and understand implementation outcomes for tele-collaborative specialty care for Veterans with Gulf War Illness (GWI). MAIN METHODS/METHODS:This study will be a hybrid type 1 randomized effectiveness-implementation trial comparing tele-collaborative specialty care to electronic consultation for Gulf War Veterans with GWI (N = 220). In tele-collaborative specialty care, the specialty provider team will deliver health coaching and problem-solving treatment to Veterans and recommend a plan for analgesic optimization. In electronic consultation, the specialty provider team will make a one-time recommendation to the primary care team for locally delivered health coaching, problem-solving treatment and analgesic optimization. The primary aim will be to determine the effectiveness of tele-collaborative specialty care as compared to electronic consultation to reduce disability related to GWI. Our secondary aim will be to understand implementation outcomes. SIGNIFICANCE/CONCLUSIONS:There is a need to improve care for Veterans with GWI. A potentially useful model to improve care is tele-collaborative specialty care, where the specialists work with the primary care provider to synergistically treat the patients. DISCUSSION/CONCLUSIONS:This is the first clinical trial to prospectively compare different models of care for Veterans with GWI. This responds to multiple calls for research to improve treatment for Veterans with GWI, including from the National Academy of Medicine.

AIMS/OBJECTIVE:We investigated whether the consumption of Concord grape juice (CGJ) was associated with increased bioavailability of serum metabolites and their potential impact on cognitive performance in Veterans with Gulf War Illness (GWI). MAIN METHODS/METHODS:Twenty-six veterans were selected from a cohort of 36 enrolled in a 24-week randomized, double-blind, Phase I/IIA clinical trial exploring whether the consumption of Concord grape juice (CGJ) was tolerable and safe in Veterans with GWI and improved cognitive function and fatigue. These 26 veterans were selected based on their completion of the entire 24-week protocol and documented adherence to the study beverage ≥80%. Differences in serum metabolite levels between CGJ and placebo at midpoint and endpoint were evaluated using two-way repeated measures ANOVA with post hoc Sidak's multiple comparison test. Bivariate correlations to assess for possible relationships between change in serum metabolite levels and change in cognitive function as measured by the Halstead Category Test-Russell Revised Version (RCAT) were also conducted. KEY FINDINGS/RESULTS:Seventy-six metabolites were identified and quantified in this study, with three (cyanidin-glucuronide, me-cyanidin-glucuronide, and me-malvidin-glucuronide) found to be significantly higher (p < 0.05) in the CGJ group compared to placebo at 24 weeks. Significant associations between changes in cognitive function and changes in serum levels of epicatechin-sulphate (r = 0.48, p = 0.01) and petunidin-glucuronide (r = 0.53, p < 0.01) from baseline to 24 weeks were also observed. SIGNIFICANCE/CONCLUSIONS:Our data suggest that dietary supplementation with CGJ is associated with increased bioavailability of specific phenolic metabolites, some of which may be correlated with cognitive performance.

AIMS/OBJECTIVE:Gulf War Illness (GWI) is a prevalent and disabling condition characterized by persistent physical symptoms. Clinical practice guidelines recommend self-management to reduce the disability from GWI. This study evaluated which GWI self-management strategies patients currently utilize and view as most effective and ineffective. MATERIALS AND METHODS/METHODS:Data were collected from 267 Veterans during the baseline assessment of a randomized clinical trial for GWI. Respondents answered 3 open-ended questions regarding which self-management strategies they use, view as effective, and view as ineffective. Response themes were coded, and code frequencies were analyzed. KEY FINDINGS/RESULTS:Response frequencies varied across questions (in-use: n = 578; effective: n = 470; ineffective: n = 297). Healthcare use was the most commonly used management strategy (38.6% of 578), followed by lifestyle changes (28.5% of 578), positive coping (13% of 578), and avoidance (13.7% of 578). When asked about effective strategies, healthcare use (25.9% of 470), lifestyle change (35.7% of 470), and positive coping (17.4% of 470) were identified. Avoidance was frequently identified as ineffective (20.2% of 297 codes), as was invalidating experiences (14.1% of 297) and negative coping (10.4% of 297). SIGNIFICANCE/CONCLUSIONS:Patients with GWI use a variety of self-management strategies, many of which are consistent with clinical practice guidelines for treating GWI, including lifestyle change and non-pharmacological strategies. This suggests opportunities for providers to encourage effective self-management approaches that patients want to use.
