Impact of Wartime Stress Exposures and Mental Health on Later-Life Functioning and Disability in Vietnam-Era Women Veterans: Findings From the Health of Vietnam-Era Women's Study.

OBJECTIVE: The effect of stress exposures and mental health sequelae on health-related outcomes is understudied among older women veterans. We examined a) the impact of wartime stress exposures on later-life functioning and disability in Vietnam-era women veterans and b) the extent to which mental health conditions known to be associated with stress-posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD)-are associated with additional later-life functioning and disability. METHODS: Data were collected in 2011 to 2012 using a mail survey and telephone interview of 4219 women veterans who were active duty during the Vietnam Era. Health functioning was assessed using the Veterans RAND 36-Item Health Survey, and disability was assessed using the World Health Organization Disability Assessment Schedule 2.0. Wartime exposures were assessed using the Women's War-Zone Stressor Scale-Revised; the Composite International Diagnostic Interview, version 3.0 was used to assess PTSD, MDD, and GAD. RESULTS: Several wartime stress exposures-including job-related pressures, dealing with death, and sexual discrimination and harassment-were associated with worse later-life health (ß ranges, -0.04 to -0.26 for functioning, 0.05 to 0.30 for disability). Current PTSD was linked with lower health functioning (physical, ß = -0.06; mental, ß = -0.15) and greater disability (ß = 0.14). Current MDD and GAD were also associated with lower mental health functioning (MDD, ß = -0.29; GAD, ß = -0.10) and greater disability (MDD, ß = 0.16; GAD, ß = 0.06). CONCLUSIONS: Results underscore the importance of detection and treatment of the potential long-term effects of wartime stressors and mental health conditions among women veterans.

HealthViEWS: mortality study of female US Vietnam era veterans, 1965-2010.

We conducted a retrospective study among 4,734 women who served in the US military in Vietnam (Vietnam cohort), 2,062 women who served in countries near Vietnam (near-Vietnam cohort), and 5,313 nondeployed US military women (US cohort) to evaluate the associations of mortality outcomes with Vietnam War service. Veterans were identified from military records and followed for 40 years through December 31, 2010. Information on underlying causes of death was obtained from death certificates and the National Death Index. Based on 2,743 deaths, all 3 veteran cohorts had lower mortality risk from all causes combined and from several major causes, such as diabetes mellitus, heart disease, chronic obstructive pulmonary disease, and nervous system disease relative to comparable US women. However, excess deaths from motor vehicle accidents were observed in the Vietnam cohort (standardized mortality ratio = 3.67, 95% confidence interval (CI): 2.30, 5.56) and in the US cohort (standardized mortality ratio = 1.91, 95% CI: 1.02, 3.27). More than two-thirds of women in the study were military nurses. Nurses in the Vietnam cohort had a 2-fold higher risk of pancreatic cancer death (adjusted relative risk = 2.07, 95% CI: 1.00, 4.25) and an almost 5-fold higher risk of brain cancer death compared with nurses in the US cohort (adjusted relative risk = 4.61, 95% CI: 1.27, 16.83). Findings of all-cause and motor vehicle accident deaths among female Vietnam veterans were consistent with patterns of postwar mortality risk among other war veterans.

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.

Challenges to be overcome using population-based sampling methods to recruit veterans for a study of post-traumatic stress disorder and traumatic brain injury.

BACKGROUND: Many investigators are interested in recruiting veterans from recent conflicts in Afghanistan and Iraq with Traumatic Brain Injury (TBI) and/or Post Traumatic Stress Disorder (PTSD). Researchers pursuing such studies may experience problems in recruiting sufficient numbers unless effective strategies are used. Currently, there is very little information on recruitment strategies for individuals with TBI and/or PTSD. It is known that groups of patients with medical conditions may be less likely to volunteer for clinical research. This study investigated the feasibility of recruiting veterans returning from recent military conflicts--Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF)--using a population-based sampling method. METHODS: Individuals were sampled from a previous epidemiological study. Three study sites focused on recruiting survey respondents (n = 445) who lived within a 60 mile radius of one of the sites. RESULTS: Overall, the successful recruitment of veterans using a population-based sampling method was dependent on the ability to contact potential participants following mass mailing. Study enrollment of participants with probable TBI and/or PTSD had a recruitment yield (enrolled/total identified) of 5.4%. We were able to contact 146 individuals, representing a contact rate of 33%. Sixty-six of the individuals contacted were screened. The major reasons for not screening included a stated lack of interest in the study (n = 37), a failure to answer screening calls after initial contact (n = 30), and an unwillingness or inability to travel to a study site (n = 10). Based on the phone screening, 36 veterans were eligible for the study. Twenty-four veterans were enrolled, (recruitment yield = 5.4%) and twelve were not enrolled for a variety of reasons. CONCLUSIONS: Our experience with a population-based sampling method for recruitment of recent combat veterans illustrates the challenges encountered, particularly contacting and screening potential participants. The screening and enrollment data will help guide recruitment for future studies using population-based methods.

Prevalence of a positive screen for PTSD among OEF/OIF and OEF/OIF-era veterans in a large population-based cohort.

Multiple studies have reported the prevalence of posttraumatic stress disorder (PTSD) in Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) veterans; however, these studies have been limited to populations who use the Department of Veterans Affairs (VA) for health care, specialty clinic populations, or veterans who deployed. The 3 aims of this study were to report weighted prevalence estimates of a positive screen for PTSD among OEF/OIF and nondeployed veterans, demographic subgroups, and VA health care system users and nonusers. The study analyzed data from the National Health Study for a New Generation of U.S. Veterans, a large population-based cohort of OEF/OIF and OEF/OIF-era veterans. The overall weighted prevalence of a positive screen for PTSD in the study population was 13.5%: 15.8% among OEF/OIF veterans and 10.9% in nondeployed veterans. Among OEF/OIF veterans, there was increased risk of a positive screen for PTSD among VA health care users (OR = 2.71), African Americans (OR = 1.61), those who served in the Army (OR = 2.67), and those on active duty (OR = 1.69). The same trend with decreased magnitude was observed in nondeployed veterans. PTSD is a significant public health problem in OEF/OIF-era veterans, and should not be considered an outcome solely related to deployment.

PTSD diagnoses among Iraq and Afghanistan veterans: comparison of administrative data to chart review.

To guide budgetary and policy-level decisions, the U.S. Department of Veterans Affairs (VA) produces quarterly reports that count the number of Iraq and Afghanistan veterans with International Classification of Diseases, 9(th) Revision, Clinical Modification (ICD-9-CM) codes for posttraumatic stress disorder (PTSD; 309.81) in their electronic medical record administrative data. We explored the accuracy of VA administrative data (i.e., diagnostic codes used for billing purposes), by comparing it to chart review evidence of PTSD (i.e., medical progress notes and all other clinical documentation contained in the entire VA medical record). We reviewed VA electronic medical records for a nationwide sample of 1,000 Iraq and Afghanistan veterans with at least one ICD-9-CM code for PTSD in their VA administrative data. Among veterans sampled, 99.9% had 2 or more ICD-9-CM codes for PTSD. Reviewing all VA electronic medical record notes for these 1,000 veterans for the full course of their VA health care history revealed that PTSD was diagnosed by a mental health provider for 89.6%, refuted for 5.6%, and PTSD was never evaluated by a mental health provider for 4.8%. VA treatment notes for the 12 months preceding chart review showed that 661 veterans sampled received a VA PTSD diagnosis during that 12-month timeframe, and of these 555 were diagnosed by a mental health provider (83.9%). Thus, the presence of an ICD-9-CM code for PTSD approximated diagnoses by VA mental health providers across time points (89.6% for entire treatment history and 83.9% for 12 months prior to chart review). Administrative data offer large-scale means to track diagnoses and treatment utilization; however, their limitations are many, including the inability to detect false-negatives.

Diagnostic accuracy of the Composite International Diagnostic Interview (CIDI 3.0) PTSD module among female Vietnam-era veterans.

The World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) posttraumatic stress disorder (PTSD) module is widely used in epidemiological studies of PTSD, yet relatively few data attest to the instrument's diagnostic utility. The current study evaluated the diagnostic utility of the CIDI 3.0 PTSD module with U. S. women Vietnam-era veterans. The CIDI and the Clinician-Administered PTSD Scale (CAPS) were independently administered to a stratified sample of 160 women, oversampled for current PTSD. Both lifetime PTSD and recent (past year) PTSD were assessed within a 3-week interval. Forty-five percent of the sample met criteria for a CAPS diagnosis of lifetime PTSD, and 21.9% of the sample met criteria for a CAPS diagnosis of past-year PTSD. Using CAPS as the diagnostic criterion, the CIDI correctly classified 78.8% of cases for lifetime PTSD (κ = .56) and 82.0% of past year PTSD cases (κ = .51). Estimates of diagnostic performance for the CIDI were sensitivity of .61 and specificity of .91 for lifetime PTSD and sensitivity of .71 and specificity of .85 for past-year PTSD. Results suggest that the CIDI has good utility for identifying PTSD, though it is a somewhat conservative indicator of lifetime PTSD as compared to the CAPS.

Investigating a clinically informed sleep disturbance threshold for physical and mental health among Gulf War Illness veterans.

Study Objectives: This study (1) assessed sleep quality and health in Gulf War veterans (GWV) meeting the Gulf War Illness (GWI) criteria and (2) compared health associations for both those meeting a "clinically disturbed sleep" threshold, and those below, as determined by the Pittsburgh Sleep Quality Index (PSQI) cutoff for military populations (≥10) on measures of physical, mental, and cognitive health. Methods: Participant data consisted of questionnaires and assessments completed prior to group assignment in a clinical trial. The sample consisted of 147 GWV, where 81.0% were males, and the median age was 53.4 years. Results: The mean (SD) PSQI global score was 12.34 (4.00) with 61% of the sample qualifying as clinically disturbed sleepers according to the cutoff (global PSQI ≥ 10). GWI veterans with PSQI scores ≥10 did not differ from others in age (p = 0.20), sex (p = 0.19), or years of education (p = 0.87), but showed worse GW-related symptomology on the Gulf War Kansas questionnaire (p < 0.01), and poorer mental health on the Veterans Rand-36 (p < 0.01). Conclusions: Disturbed sleep was associated with measures of pain, fatigue, and cognitive health. Our results suggest that a previously determined clinical threshold for clinically disturbed sleep is useful when examining the health status of the study population. Given that GWI is associated with elevated PSQI scores and a high frequency of disturbed sleep, cutoffs determining sleep health should be sensitive to population exposures and health history to improve interpretability.

Mental Health and Cognition in Women Veterans Enrolled in the Health of Vietnam Era Veteran Women's Study (HealthViEWS).

Objective: This analysis explored relationships between mental health symptoms and conditions and cognitive function in a cohort of Vietnam-era women veterans from the Health of Vietnam Era Veteran Women's Study (HealthViEWS). Methods: Vietnam-era women veterans completed a mail survey assessing self-reported symptom severity of posttraumatic stress disorder (PTSD) and depression. A telephone-based structured interview assessed mental health conditions and cognitive function (telephone interview for cognitive status [TICS]). Participants were categorized using a TICS threshold of ≤29 to designate possible cognitive impairment versus nonimpaired. Separate logistic regression models were used to determine associations between possible cognitive impairment and each self-reported and interviewer-rated assessment of PTSD and depression while adjusting for age, education, race, marital status, and wartime service location. Results: The sample consisted of 4,077 women veterans who were ≥60 years old and completed the TICS. Of these women, 7.20% were categorized with possible cognitive impairment. Logistic regression models indicated that self-reported PTSD and depression symptom severity were each significantly associated with higher odds of possible cognitive impairment (adjusted odds ratios [aOR]: 1.03 [95% confidence interval [CI]: 1.02-1.04] and 1.07 [95% CI: 1.04-1.09], respectively). Women veterans with a probable diagnosis of depression had higher odds of possible cognitive impairment compared to those without depression (aOR: 1.61 [95% CI: 1.07-2.42]). No association was found for probable diagnosis of PTSD. Conclusions: Although further examination remains necessary, results suggest that Vietnam-era women veterans with self-reported PTSD and depression symptom severity or a probable diagnosis of depression may benefit from screening of cognitive function to inform clinical care.

Gulf War Illness: A Randomized Controlled Trial Combining Mindfulness Meditation and Auricular Acupuncture.

Background: Many Gulf War (GW) Veterans report chronic symptoms including pain, fatigue, and cognitive impairment, commonly defined as Gulf War Illness (GWI). Complementary and integrative health (CIH) therapies may potentially improve multiple symptoms of GWI. Objective: To examine the effectiveness of combining 2 commonly available CIH therapies, mindfulness meditation and auricular acupuncture, in improving health-related functioning and multiple symptom domains of GWI (e.g., pain, fatigue). Methods: This study was a randomized controlled trial in which Veterans with GWI were randomly assigned to either the intervention group (n = 75), wherein they received 2 distinct CIH therapies - mindfulness meditation and auricular acupuncture, or the active control group, wherein they received a GW Health Education (GWHE) program (n = 74), each lasting 8 weeks. Self-report health measures were assessed at baseline, endpoint, and 3 month follow-up. Results: In the intention-to-treat analyses, there were significant between-group differences for mental-health related functioning, fatigue, depression symptoms, and Kansas total severity scores for symptoms in which the CIH group had improved scores for these outcomes at endpoint compared to the GWHE group (all P ≤ .05). The CIH group also had significant reductions in pain interference at endpoint and follow-up compared to baseline (estimated marginal mean difference: -2.52 and -2.22, respectively; all P = .01), whereas no significant changes were observed in the GWHE group. For pain characteristics, the GWHE group had a worsening of pain at endpoint compared to baseline (estimated marginal mean difference: +2.83; P = .01), while no change was observed in the CIH group. Conclusion: Findings suggest a possible beneficial effect of combining 2 CIH therapies, mindfulness meditation and auricular acupuncture, in reducing overall symptom severity and individual symptom domains of fatigue, musculoskeletal, and mood/cognition in Veterans with GWI. Trial Registration: Clinical Trials identifier NCT02180243.

A Cross-sectional Cohort Study to Assess Long-term Neurocognitive and Psychiatric Symptoms of Mefloquine Use in Veterans.

INTRODUCTION: To evaluate the associations between neurocognitive and psychiatric health outcomes with mefloquine or any antimalarial exposure. MATERIALS AND METHODS: Medical records were systematically reviewed to identify veterans that indicated antimalarial medication use. Linear regression was performed to examine associations between mefloquine/antimalarial exposure and health outcomes. The mefloquine-exposed group was further compared with normative populations for the same health outcomes. RESULTS: In the adjusted models, no significant differences were noted between the two exposure groups and the unexposed group for any of the health measures (P-value > 0.05). When compared to normative population samples, the mefloquine-exposed group had poorer health and greater neurobehavioral symptom severity or cognitive complaints. CONCLUSION: This study suggests that mefloquine use by veterans referred for intensive evaluation of their military deployment exposures and health was not associated with increased, long-term, neurocognitive/psychiatric symptoms compared to unexposed veterans.

'She thought the same way I that I thought:' a qualitative study of patient-provider concordance among Gulf War Veterans with Gulf War Illness.

Objective: Medically unexplained symptoms (MUS), such as chronic fatigue syndrome, irritable bowel syndrome, and Gulf War Illness (GWI), are difficult to treat. Concordance-shared understanding between patient and provider about illness causes, course, and treatment-is an essential component of high-quality care for people with MUS. This qualitative paper focuses on the experiences of United States military Veterans living with GWI who have endured unique healthcare challenges. Methods & Measures: Qualitative interviews were conducted with 31 Veterans with GWI to explore factors that contribute to and detract from concordance with their Veteran Affairs (VA) healthcare providers. In addition to being seen by VA primary care, over half of participants also sought care at a War Related Illness and Injury Study Center, which specializes in post-deployment health. Deductive and inductive codes were used to organize the data, and themes were identified through iterative review of coded data. Results: Major themes associated with patient-provider concordance included validation of illness experiences, perceived provider expertise in GWI/MUS, and trust in providers. Invalidation, low provider expertise, and distrust detracted from concordance. Conclusion: These findings suggest providers can foster concordance with MUS patients by legitimizing patients' experiences, communicating knowledge about MUS, and establishing trust.

A regulatory pathway model of neuropsychological disruption in Havana syndrome.

Introduction: In 2016 diplomatic personnel serving in Havana, Cuba, began reporting audible sensory phenomena paired with onset of complex and persistent neurological symptoms consistent with brain injury. The etiology of these Anomalous Health Incidents (AHI) and subsequent symptoms remains unknown. This report investigates putative exposure-symptom pathology by assembling a network model of published bio-behavioral pathways and assessing how dysregulation of such pathways might explain loss of function in these subjects using data available in the published literature. Given similarities in presentation with mild traumatic brain injury (mTBI), we used the latter as a clinically relevant means of evaluating if the neuropsychological profiles observed in Havana Syndrome Havana Syndrome might be explained at least in part by a dysregulation of neurotransmission, neuro-inflammation, or both. Method: Automated text-mining of >9,000 publications produced a network consisting of 273 documented regulatory interactions linking 29 neuro-chemical markers with 9 neuropsychological constructs from the Brief Mood Survey, PTSD Checklist, and the Frontal Systems Behavior Scale. Analysis of information flow through this network produced a set of regulatory rules reconciling to within a 6% departure known mechanistic pathways with neuropsychological profiles in N = 6 subjects. Results: Predicted expression of neuro-chemical markers that jointly satisfy documented pathways and observed symptom profiles display characteristically elevated IL-1B, IL-10, NGF, and norepinephrine levels in the context of depressed BDNF, GDNF, IGF1, and glutamate expression (FDR < 5%). Elevations in CRH and IL-6 were also predicted unanimously across all subjects. Furthermore, simulations of neurological regulatory dynamics reveal subjects do not appear to be "locked in" persistent illness but rather appear to be engaged in a slow recovery trajectory. Discussion: This computational analysis of measured neuropsychological symptoms in Havana-based diplomats proposes that these AHI symptoms may be supported in part by disruption of known neuroimmune and neurotransmission regulatory mechanisms also associated with mTBI.

Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Clinical Normative Data for Gulf War Veterans.

OBJECTIVE: Heterogenous test batteries and methods applied in neurocognitive research on Gulf War Veterans (GWVs) limit the translation of findings to clinical practice. A clinical data set is necessary. METHODS: Neurocognitive screening data from treatment-seeking GWVs were collected from multiple sites and compiled, informed by consideration of performance validity. RESULTS: Repeatable Battery for the Assessment of Neuropsychological Status scores revealed the cognitive profile for GWVs (n = 189) as poorer across multiple domains when compared with similarly educated, nonveteran peers. However, mean scores generally remained within normal clinical limits. Data tables are presented to establish a comparison group for use in clinical care. CONCLUSIONS: When assessing cognitive symptoms in GWVs, attention to education level and interpretation of subtle deficits is warranted. Current results highlight the importance of nuanced translation of neurocognitive research findings into clinical practice with GWVs.

Mapping the network biology of metabolic response to stress in posttraumatic stress disorder and obesity.

The co-occurrence of stress-induced posttraumatic stress disorder (PTSD) and obesity is common, particularly among military personnel but the link between these conditions is unclear. Individuals with comorbid PTSD and obesity manifest other physical and psychological problems, which significantly diminish their quality of life. Current understanding of the pathways connecting stress to PTSD and obesity is focused largely on behavioral mediators alone with little consideration of the biological regulatory mechanisms that underlie their co-occurrence. In this work, we leverage prior knowledge to systematically highlight such bio-behavioral mechanisms and inform on the design of confirmatory pilot studies. We use natural language processing (NLP) to extract documented regulatory interactions involved in the metabolic response to stress and its impact on obesity and PTSD from over 8 million peer-reviewed papers. The resulting network describes the propagation of stress to PTSD and obesity through 34 metabolic mediators using 302 documented regulatory interactions supported by over 10,000 citations. Stress jointly affected both conditions through 21 distinct pathways involving only two intermediate metabolic mediators out of a total of 76 available paths through this network. Moreover, oxytocin (OXT), Neuropeptide-Y (NPY), and cortisol supported an almost direct propagation of stress to PTSD and obesity with different net effects. Although stress upregulated both NPY and cortisol, the downstream effects of both markers are reported to relieve PTSD severity but exacerbate obesity. The stress-mediated release of oxytocin, however, was found to concurrently downregulate the severity of both conditions. These findings highlight how a network-informed approach that leverages prior knowledge might be used effectively in identifying key mediators like OXT though experimental verification of signal transmission dynamics through each path will be needed to determine the actual likelihood and extent of each marker's participation.

Acoustic and language analysis of speech for suicidal ideation among US veterans.

BACKGROUND: Screening for suicidal ideation in high-risk groups such as U.S. veterans is crucial for early detection and suicide prevention. Currently, screening is based on clinical interviews or self-report measures. Both approaches rely on subjects to disclose their suicidal thoughts. Innovative approaches are necessary to develop objective and clinically applicable assessments. Speech has been investigated as an objective marker to understand various mental states including suicidal ideation. In this work, we developed a machine learning and natural language processing classifier based on speech markers to screen for suicidal ideation in US veterans. METHODOLOGY: Veterans submitted 588 narrative audio recordings via a mobile app in a real-life setting. In addition, participants completed self-report psychiatric scales and questionnaires. Recordings were analyzed to extract voice characteristics including prosodic, phonation, and glottal. The audios were also transcribed to extract textual features for linguistic analysis. We evaluated the acoustic and linguistic features using both statistical significance and ensemble feature selection. We also examined the performance of different machine learning algorithms on multiple combinations of features to classify suicidal and non-suicidal audios. RESULTS: A combined set of 15 acoustic and linguistic features of speech were identified by the ensemble feature selection. Random Forest classifier, using the selected set of features, correctly identified suicidal ideation in veterans with 86% sensitivity, 70% specificity, and an area under the receiver operating characteristic curve (AUC) of 80%. CONCLUSIONS: Speech analysis of audios collected from veterans in everyday life settings using smartphones offers a promising approach for suicidal ideation detection. A machine learning classifier may eventually help clinicians identify and monitor high-risk veterans.

The relationship between Gulf War Illness symptom severity and heart rate variability: A pilot study.

INTRODUCTION: Gulf War Illness (GWI) is a chronic multisymptom illness affecting 250,000+ veterans of the '90-'91 Gulf War which remains under-explored in terms of its physiological characteristics. We investigated whether subjective GWI symptom severity scores were related to objective measures of autonomic nervous system activity. METHODS: We estimated activity in the two major branches of the autonomic nervous system (the parasympathetic nervous system [PNS] and the sympathetic nervous system [SNS]) via metrics of heart rate variability in a sample of Veterans who met established criteria for GWI with varying degrees of self-reported symptom severity. We hypothesized that subjective symptom severity scores would be inversely related to PNS activity and positively related to SNS activity. RESULTS: Significant negative relationships were observed between the root mean square of successive differences of beat-to-beat intervals (a measure of PNS activity) and symptom severity, both overall and across specific GWI symptom categories (sp. fatigue [r = -0.574], gastrointestinal [r = -0.544]). Furthermore, significant positive relationships were observed between the cardiac sympathetic index and symptom severity, both overall and across specific symptom categories (sp. cognitive [r = 0.721], fatigue [r = 0.560], gastrointestinal [r = 0.694], skin [r = 0.686]). CONCLUSIONS: Metrics of PNS activation revealed a negative relationship with self-reported symptom severity, while metrics of SNS activation revealed a positive relationship. The present results improve our understanding of the physiology of GWI and provide a new window from which to consider this medically unexplained illness.

Using the MMPI to assess reported cognitive disturbances and somatization as a core feature of complex PTSD.

Minnesota Multiphasic Personality Inventory (MMPI) clinical scales as well as 4 sets of MMPI items known to be sensitive to neurological dysfunction (closed head injury, cerebrovascular disorder) were administered to survivors of childhood physical and/or sexual abuse and to non-abused adults. As predicted, relative to the comparison group of psychiatric patients, the abused participants scored significantly higher on Scale 8 (Schizophrenia) and on all 4 sets of items associated with neurological dysfunction. The results suggest that early abuse/trauma is associated with cognitive disturbances and somatization. Findings appear to support the conceptualization of these psychophysical experiences as a central part of what is often called "complex posttraumatic stress disorder." Limitations and suggestions for further study are discussed.

Social rehabilitation for military veterans with traumatic brain injury, psychological trauma, and chronic neuropsychiatric symptoms: Intervention development and initial outcomes.

OBJECTIVE: A subset of military veterans who have experienced both traumatic brain injury and psychological trauma present with chronic neuropsychiatric symptoms and experience persistent obstacles to social reintegration. This project aimed to develop a novel treatment targeting the unmet social rehabilitation needs of these veterans. Initial intervention development, feasibility, and outcome data are explored. METHOD: Four treatment groups were conducted (n = 20). A treatment workbook was developed during Groups 1 and 2 (n = 10) and research data were collected from Groups 3 and 4 (n = 10). RESULTS: There was a 0% attrition rate across all groups with unanimous requests for additional sessions. T test effect sizes were analyzed with bias-corrected Hedges' g. Improvements were observed on measures of depression (p = .026, g = 0.73), empathic perspective taking (p = .007, g = 0.94), social cognition (p = .002-.678, g = 0.27-1.30 across multiple measures), social relationships (p = .007, g = 1.50), traumatic brain injury-related quality of life (social: p = .014, g = 0.68, emotional: p = .009, g = 1.28) and nonsocial executive functioning (p = .006, g = 0.54). CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Preliminary evidence from this exploratory study suggests that targeting multiple layers of social competence using a combined psychotherapy and cognitive rehabilitation approach holds promise. Larger, controlled studies are needed to further evaluate the feasibility and efficacy of this intervention. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Age-associated predictors of medication adherence in HIV-positive adults: health beliefs, self-efficacy, and neurocognitive status.

OBJECTIVE: Although most agree that poor adherence to antiretrovirals is a common problem, relatively few factors have been shown to consistently predict treatment failure. In this study, a theoretical framework encompassing demographic characteristics, health beliefs/attitudes, treatment self-efficacy, and neurocognitive status was examined in relationship to highly active antiretroviral therapy adherence. DESIGN: Prospective, cross-sectional observational design. MAIN OUTCOME MEASURES: Neuropsychological test performance, health beliefs and attitudes, and medication adherence tracked over a 1-month period using electronic monitoring technology (Medication Event Monitoring System caps). RESULTS: The rate of poor adherence was twice as high among younger participants than with older participants (68% and 33%, respectively). Results of binary logistic regression revealed that low self-efficacy and lack of perceived treatment utility predicted poor adherence among younger individuals, whereas decreased levels of neurocognitive functioning remained the sole predictor of poor adherence among older participants. CONCLUSION: These data support components of the health beliefs model in predicting medication adherence among younger HIV-positive individuals. However, risk of adherence failure in those ages 50 years and older appears most related to neurocognitive status.
