Tailored vs. General COVID-19 prevention for adults with mental disabilities residing in group homes: a randomized controlled effectiveness-implementation trial.

BACKGROUND: People with serious mental illness (SMI) and people with intellectual disabilities/developmental disabilities (ID/DD) are at higher risk for COVID-19 and more severe outcomes. We compare a tailored versus general best practice COVID-19 prevention program in group homes (GHs) for people with SMI or ID/DD in Massachusetts (MA). METHODS: A hybrid effectiveness-implementation cluster randomized control trial compared a four-component implementation strategy (Tailored Best Practices: TBP) to dissemination of standard prevention guidelines (General Best-Practices: GBP) in GHs across six MA behavioral health agencies. GBP consisted of standard best practices for preventing COVID-19. TBP included GBP plus four components including: (1) trusted-messenger peer testimonials on benefits of vaccination; (2) motivational interviewing; (3) interactive education on preventive practices; and (4) fidelity feedback dashboards for GHs. Primary implementation outcomes were full COVID-19 vaccination rates (baseline: 1/1/2021-3/31/2021) and fidelity scores (baseline: 5/1/21-7/30/21), at 3-month intervals to 15-month follow-up until October 2022. The primary effectiveness outcome was COVID-19 infection (baseline: 1/1/2021-3/31/2021), measured every 3 months to 15-month follow-up. Cumulative incidence of vaccinations were estimated using Kaplan-Meier curves. Cox frailty models evaluate differences in vaccination uptake and secondary outcomes. Linear mixed models (LMMs) and Poisson generalized linear mixed models (GLMMs) were used to evaluate differences in fidelity scores and incidence of COVID-19 infections. RESULTS: GHs (n=415) were randomized to TBP (n=208) and GBP (n=207) including 3,836 residents (1,041 ID/DD; 2,795 SMI) and 5,538 staff. No differences were found in fidelity scores or COVID-19 incidence rates between TBP and GBP, however TBP had greater acceptability, appropriateness, and feasibility. No overall differences in vaccination rates were found between TBP and GBP. However, among unvaccinated group home residents with mental disabilities, non-White residents achieved full vaccination status at double the rate for TBP (28.6%) compared to GBP (14.4%) at 15 months. Additionally, the impact of TBP on vaccine uptake was over two-times greater for non-White residents compared to non-Hispanic White residents (ratio of HR for TBP between non-White and non-Hispanic White: 2.28, p = 0.03). CONCLUSION: Tailored COVID-19 prevention strategies are beneficial as a feasible and acceptable implementation strategy with the potential to reduce disparities in vaccine acceptance among the subgroup of non-White individuals with mental disabilities.

Predictors of COVID-19 infection and hospitalization in group homes for individuals with intellectual and/or developmental disabilities.

BACKGROUND: More than seven million people with intellectual and/or developmental disabilities (ID/DD) live in the US and may face an elevated risk for COVID-19. OBJECTIVE: To identify correlates of COVID-19 and related hospitalizations among people with ID/DD in group homes in Massachusetts. METHODS: We collected data during March 1, 2020-June 30, 2020 (wave 1) and July 1, 2020-March 31, 2021 (wave 2) from the Massachusetts Department of Public Health and six organizations administering 206 group homes for 1035 residents with ID/DD. The main outcomes were COVID-19 infections and related hospitalizations. We fit multilevel Cox proportional hazards models to estimate associations with observed predictors and assess contextual home- and organizational-level effects. RESULTS: Compared with Massachusetts residents, group home residents had a higher age-adjusted rate of COVID-19 in wave 1 (incidence rate ratio [IRR], 12.06; 95 % confidence interval [CI], 10.51-13.84) and wave 2 (IRR, 2.47; 95 % CI, 2.12-2.88) and a higher age-adjusted rate of COVID-19 hospitalizations in wave 1 (IRR, 17.64; 95 % CI, 12.59-24.70) and wave 2 (IRR, 4.95; 95 % CI, 3.23-7.60). COVID-19 infections and hospitalizations were more likely among residents aged 65+ and in group homes with 6+ resident beds and recent infection among staff and residents. CONCLUSIONS: Aggressive efforts to decrease resident density, staff-to-resident ratios, and staff infections through efforts such as vaccination, in addition to ongoing access to personal protective equipment and COVID-19 testing, may reduce COVID-19 and related hospitalizations in people with ID/DD living in group homes.

COVID-19-Related Outcomes Among Group Home Residents with Serious Mental Illness in Massachusetts in the First Year of the Pandemic.

This study examined COVID-19 infection and hospitalizations among people with serious mental illness who resided in residential care group homes in Massachusetts during the first year of the COVID-19 pandemic. The authors analyzed data on 2261 group home residents and COVID-19 data from the Massachusetts Department of Public Health. Outcomes included positive COVID-19 tests and COVID-19 hospitalizations March 1, 2020-June 30, 2020 (wave 1) and July 1, 2020-March 31, 2021 (wave 2). Associations between hazard of outcomes and resident and group home characteristics were estimated using multi-level Cox frailty models including home- and city-level frailties. Between March 2020 and March 2021, 182 (8%) residents tested positive for COVID-19, and 51 (2%) had a COVID-19 hospitalization. Compared with the Massachusetts population, group home residents had age-adjusted rate ratios of 3.0 (4.86 vs. 1.60 per 100) for COVID infection and 13.5 (1.99 vs. 0.15 per 100) for COVID hospitalizations during wave 1; during wave 2, the rate ratios were 0.5 (4.55 vs. 8.48 per 100) and 1.7 (0.69 vs. 0.40 per 100). In Cox models, residents in homes with more beds, higher staff-to-resident ratios, recent infections among staff and other residents, and in cities with high community transmission risk had greater hazard of COVID-19 infection. Policies and interventions that target group home-specific risks are needed to mitigate adverse communicable disease outcomes in this population.Clinical Trial Registration Number This study provides baseline (i.e., pre-randomization) data from a clinical trial study NCT04726371.

Caring for Dementia Caregivers: Understanding Caregiver Stress During the COVID-19 Pandemic.

More than 16 million Americans provide unpaid care for someone with Alzheimer's disease and related dementias (ADRD). During the COVID-19 pandemic, unpaid caregivers experienced increased chronic severe stress from widespread closures and social distancing. We conducted eight surveys from March 2020 to March 2021 among a cohort of over 10,000 individuals. Cross-sectional analysis was conducted to investigate frequency and ratios of groups reporting increased stress across surveys. A longitudinal analysis was also performed with the 1,030 participants who took more than one survey. We found a growing crisis among dementia caregivers: By Survey 8, current caregivers reported 2.9 times higher stress levels than the comparator group. By that time, 64% of current caregivers reported having multiple stress symptoms typically found in people experiencing severe stress. Both analyses reported increased levels of stressors over time that were more associated with certain caregiver groups. Our findings underscore the urgent need for public policy initiatives and supportive community infrastructure to support ADRD caregivers.

Group Home Staff Experiences With Work and Health in the COVID-19 Pandemic in Massachusetts.

Importance: Direct reports of the experiences of staff working in group homes for people with serious mental illness (SMI) and/or intellectual or developmental disabilities (ID/DD) are rarely reported. Hearing from workers about their experiences in the COVID-19 pandemic may inform future workforce and public policy. Objective: To gather baseline data on worker experience with the perceived effects of COVID-19 on health and work in the pandemic prior to initiating an intervention to mitigate the spread of COVID-19 and to measure differences in worker experience by gender, race, ethnicity, education, and resident population served (persons with SMI and/or IDD/DD). Design, Setting, and Participants: This mixed-mode, cross-sectional survey study was conducted using online then paper-based self-administration from May to September 2021 at the end of the first year of the pandemic. Staff working in 415 group homes that provided care within 6 Massachusetts organizations serving adults aged 18 years or older with SMI and/or ID/DD were surveyed. The eligible survey population included a census of staff who were currently employed in participating group homes during the study period. A total of 1468 staff completed or partially completed surveys. The overall survey response rate was 44% (range by organization, 20% to 52%). Main Outcomes and Measures: Self-reported experiential outcomes were measured in work, health, and vaccine completion. Bivariate and multivariate analyses explore experiences by gender, race, ethnicity, education, trust in experts and employers, and population served. Results: The study population included 1468 group home staff (864 [58.9%] women; 818 [55.7%] non-Hispanic Black; 98 [6.7%] Hispanic or Latino). A total of 331 (22.5%) group home staff members reported very serious perceived effects on health; 438 (29.8%) reported very serious perceived effects on mental health; 471 (32.1%) reported very serious perceived effects on health of family and friends; and 414 reported very serious perceived effects (28.2%) on access to health services, with statistically significant differences observed by race and ethnicity. Vaccine acceptance was higher among persons with higher educational attainment and trust in scientific expertise and lower among persons who self-reported as Black or Hispanic/Latino. A total of 392 (26.7%) respondents reported needing support for health needs, and 290 (19.8%) respondents reported needing support for loneliness or isolation. Conclusions and Relevance: In this survey study, approximately one-third of group home workers reported serious personal health and access to health care barriers during the first year of the COVID-19 pandemic in Massachusetts. Addressing unmet health needs and access to health and mental health services, including inequities and disparities by race, ethnicity, and education, should benefit staff health and safety, as well as that of the individuals with disabilities who rely on them for support and care.

Best practices to reduce COVID-19 in group homes for individuals with serious mental illness and intellectual and developmental disabilities: Protocol for a hybrid type 1 effectiveness-implementation cluster randomized trial.

BACKGROUND: People with serious mental illness (SMI) and intellectual disabilities and/or developmental disabilities (ID/DD) living in group homes (GHs) and residential staff are at higher risk for COVID-19 infection, hospitalization, and death compared with the general population. METHODS: We describe a hybrid type 1 effectiveness-implementation cluster randomized trial to assess evidence-based infection prevention practices to prevent COVID-19 for residents with SMI or ID/DD and the staff in GHs. The trial will use a cluster randomized design in 400 state-funded GHs in Massachusetts for adults with SMI or ID/DD to compare effectiveness and implementation of "Tailored Best Practices" (TBP) consisting of evidence-based COVID-19 infection prevention practices adapted for residents with SMI and ID/DD and GH staff; to "General Best Practices" (GBP), consisting of required standard of care reflecting state and federal standard general guidelines for COVID-19 prevention in GHs. External (i.e., community-based research staff) and internal (i.e., GH staff leadership) personnel will facilitate implementation of TBP. The primary effectiveness outcome is incident SARS-CoV-2 infection and secondary effectiveness outcomes include COVID-19-related hospitalizations and mortality in GHs. The primary implementation outcomes are fidelity to TBP and rates of COVID-19 vaccination. Secondary implementation outcomes are adoption, adaptation, reach, and maintenance. Outcomes will be assessed at baseline, 3-, 6-, 9-, 12-, and 15-months post-randomization. CONCLUSIONS: This study will advance knowledge on comparative effectiveness and implementation of two different strategies to prevent COVID-19-related infection, morbidity, and mortality and promote fidelity and adoption of these interventions in high-risk GHs for residents with SMI or ID/DD and staff.

Engaging and Supporting Young Children and their Families in Early Childhood Mental Health Services: The Role of the Family Partner.

This study explores the role of family partners, peer professionals with lived experiences of raising a child with behavioral health needs, and their value in primary and community-care based mental health services for young children aged 0-8 years. Interviews and focus groups were conducted with staff, leadership, and caregiver participants (n = 38) from two early childhood mental health programs and analyzed using thematic analysis. Five interdependent themes emerged: (1) the centrality of lived experience to the family partner role; (2) the importance of the family partner in family engagement and relationship building; (3) the value added by the family partner in navigating systems; (4) the ability of the family partner to build skills and empower caregivers; (5) the role of the family partner in alleviating caregiver stress and other mental health concerns. Adapting and expanding the role of family partners will improve effective mental health care for children and their caregivers.

Epidemiology of Chronic Effects of Traumatic Brain Injury.

Although many patients diagnosed with traumatic brain injury (TBI), particularly mild TBI, recover from their symptoms within a few weeks, a small but meaningful subset experience symptoms that persist for months or years after injury and significantly impact quality of life for the person and their family. Factors associated with an increased likelihood of negative TBI outcomes include not only characteristics of the injury and injury mechanism, but also the person's age, pre-injury status, comorbid conditions, environment, and propensity for resilience. In this article, as part of the Brain Trauma Blueprint: TBI State of the Science framework, we examine the epidemiology of long-term outcomes of TBI, including incidence, prevalence, and risk factors. We identify the need for increased longitudinal, global, standardized, and validated assessments on incidence, recovery, and treatments, as well as standardized assessments of the influence of genetics, race, ethnicity, sex, and environment on TBI outcomes. By identifying how epidemiological factors contribute to TBI outcomes in different groups of persons and potentially impact differential disease progression, we can guide investigators and clinicians toward more-precise patient diagnosis, along with tailored management, and improve clinical trial designs, data evaluation, and patient selection criteria.

Phenotyping the Spectrum of Traumatic Brain Injury: A Review and Pathway to Standardization.

It is widely appreciated that the spectrum of traumatic brain injury (TBI), mild through severe, contains distinct clinical presentations, variably referred to as subtypes, phenotypes, and/or clinical profiles. As part of the Brain Trauma Blueprint TBI State of the Science, we review the current literature on TBI phenotyping with an emphasis on unsupervised methodological approaches, and describe five phenotypes that appear similar across reports. However, we also find the literature contains divergent analysis strategies, inclusion criteria, findings, and use of terms. Further, whereas some studies delineate phenotypes within a specific severity of TBI, others derive phenotypes across the full spectrum of severity. Together, these facts confound direct synthesis of the findings. To overcome this, we introduce PhenoBench, a freely available code repository for the standardization and evaluation of raw phenotyping data. With this review and toolset, we provide a pathway toward robust, data-driven phenotypes that can capture the heterogeneity of TBI, enabling reproducible insights and targeted care.

Vicarious traumatization among child welfare and child protection professionals: A systematic review.

BACKGROUND: Many individuals and organizations experience vicarious trauma, defined as exposure to traumatic experiences of others. Those who work with children traumatized by abuse and/or neglect, including, but not limited to, child welfare, child protection, counselors, healthcare providers, advocates, law enforcement, and prosecutors investigating crimes against children, are exposed to traumatic stories daily in their work. Negative reactions to this witnessing of other people's trauma results in vicarious traumatization (also referred to as secondary traumatic stress) which can manifest as mental, physical, emotional, spiritual, work-related and/or social consequences. METHODS: A review of research literature on the epidemiology of vicarious traumatization among child welfare professionals was conducted. A systematic search strategy was employed using relevant research databases (PubMed, PsychInfo, PILOTS, and EBSCO) for publications from 1995 to 2018. A four-phase PRISMA selection process was employed. Search terms included vicarious trauma/related terms and child welfare/child protection professions. Trained reviewers considered articles meeting inclusion criteria including: (1) child welfare professions; (2) vicarious traumatization/related terms; and (3) analysis of epidemiological data on prevalence, risk/protective factors, or manifestation of vicarious traumatization. RESULTS: Initially 7,895 unique manuscripts were identified. After multi-stage screening, a total of 39 articles were included. Findings regarding the epidemiology of vicarious traumatization are summarized. CONCLUSIONS: While exposure to traumatic narratives of those they serve is inevitable for those working in child welfare and child protection professions, the growing research base shows potential for preventing negative impacts and promoting positive outcomes of this empathic work. Identification of additional risk/protective factors and future development and evaluation of evidence-based interventions are important next steps.

A study of contact lens compliance in a non-clinical setting.

PURPOSE: To evaluate soft contact lens replacement, overnight (ON) wear, and contact lens case compliance in a non-clinical sample. METHODS: Subjects (n = 297) were recruited at the Center for Science and Industry (COSI) in Columbus, Ohio. Adult (≥ 18 years) soft contact lens wearers completed a survey about contact lens replacement, ON contact lens wear, and contact lens case replacement habits. RESULTS: Two-week replacement lenses (according to the manufacturer's replacement schedule [MRS]) were most common (45.5%), followed by monthly (34.3%) and daily replacement (20.2%). Non-compliance with replacement schedule was reported in 38.7% of subjects. Age (p = 0.02), years of lens wear (p = 0.02), and MRS (p <0.0001) affected replacement compliance. Post-hoc analysis showed daily replacement wearers were more compliant than two-week (p <0.0001) and monthly (p <0.0001) replacement wearers with prescribed lens replacement. Non-compliance with prescribed ON wear was reported in 23.9% of subjects. Subjects who were non-compliant with lens replacement were more likely to be non-compliant with ON wear (p = 0.02) and had worn contact lenses for less time (p = 0.02). Of the subjects who used contact lens cases, 74.6% were unsure when they should replace their case. Frequency of case replacement was not associated with age (p = 0.5), gender (p = 0.5), years of contact lens wear (p = 0.7), MRS (p = 0.4), replacement compliance (p = 0.3), or ON wear compliance (p = 0.7). CONCLUSIONS: Daily replacement wearers were most likely to be compliant with contact lens replacement, but all subjects, including daily replacement wearers, had similar ON wear non-compliance. Non-compliant lens replacement was associated with non-compliant ON wear, but contact lens case replacement was not related to either compliance category. The majority of subjects had no knowledge of proper contact lens case replacement, despite compliance in other categories.

Enhancing Early Childhood Mental Health Primary Care Services: Evaluation of MA Project LAUNCH.

Objectives The purpose of this study was to evaluate the efficacy of an innovative early childhood mental health intervention, Massachusetts Project LAUNCH. Early childhood mental health clinicians and family partners (paraprofessionals with lived experience) were embedded within community pediatric medical homes. Methods A longitudinal study design was used to test the hypotheses that (1) children who received services would experience decreased social, emotional and behavioral problems over time and (2) caregivers' stress and depressive symptoms would decrease over time. Families who were enrolled in services and who consented to participate in the evaluation study were included in analyses (N = 225). Individual growth models were used to test longitudinal effects among MA LAUNCH participants (children and caregivers) over three time points using screening tools. Results Analyses showed that LAUNCH children who scored in age-specific clinically significant ranges of social, emotional and behavioral problems at Time 1 scored in the normal range on average by Time 3. Caregivers' stress and depressive symptoms also declined across the three time points. Results support hypotheses that the LAUNCH intervention improved social and emotional health for children and caregivers. Conclusions for Practice This study led to sustainability efforts, an expansion of the model to three additional communities across the state and development of an online toolkit for other communities interested in implementation.

The impact of lifestyle medicine continuing education on provider knowledge, attitudes, and counseling behaviors.

BACKGROUND: There is a need for effective continuing medical education (CME) programs to increase healthcare providers' knowledge and skills in lifestyle medicine so that healthcare providers are better equipped to assist patients in adopting and maintaining healthier lifestyle behaviors. AIMS: To evaluate the impact of five live face-to-face CME programs in lifestyle medicine on providers' barriers, knowledge, confidence, and professional counseling behaviors. METHODS: 200 participants completed researcher-generated surveys before and 90 days after each CME program. Paired t-tests measured significant changes for all outcome variables, and regression analyses assessed predictors of these changes. RESULTS: Barriers that were targeted during the programs, i.e. lack of knowledge/skills, lack of materials, and perceived poor patient compliance showed highly significant improvement. Participants also reported significant changes in knowledge, confidence, and counseling behaviors in the areas of exercise and stress management. Some improvements occurred in areas that the CME programs did not target as much, i.e. nutrition, smoking, and weight management. The greatest predictor of change was the baseline level of scores. Those participants who could most benefit from change did show the largest improvements. CONCLUSIONS: Live CME programs can be effective in educating healthcare providers about topics within the rapidly expanding field of lifestyle medicine.

Effects of military trauma exposure on women veterans' use and perceptions of Veterans Health Administration care.

BACKGROUND: Few studies have addressed how military trauma exposure, particularly sexual assault and combat exposure, affects women veterans' use and perceptions of Veterans Health Administration (VHA) care. OBJECTIVE: The aim of the present study was to evaluate the effects of military sexual assault and combat exposure on women veterans' use and perceptions of different aspects of VHA care. DESIGN: Cross-sectional telephone survey of a national sample of women veterans. PARTICIPANTS: Women from the VA's National Registry of Women Veterans. MEASUREMENTS: Sociodemographic characteristics, VHA care utilization, perceptions of care. RESULTS: Women veterans with histories of military sexual assault reported more use of VHA services, but less satisfaction, poorer perceptions of VHA facilities and staff, and more problems with VHA services compared to women veterans without histories of sexual assault. Combat exposure was related to more problems with VHA staff, although few other differences were observed for women with and without histories of combat exposure. CONCLUSIONS: Findings provide information on areas that can be targeted with respect to caring for women veterans exposed to military sexual trauma and combat exposure, including improving interactions with VHA staff and the ease of using VHA services.

Barriers to Veterans Health Administration care in a nationally representative sample of women veterans.

BACKGROUND: Women veterans are generally less healthy than their nonveteran female counterparts or male veterans. Accumulating evidence suggests there may be barriers to women veterans' access to and use of Veterans Health Administration (VHA) care. OBJECTIVE: To document perceived and/or actual barriers to care in a nationally representative sample of women veterans and examine associations with VHA use. DESIGN: Cross-sectional telephone survey. PARTICIPANTS: Women who are current and former users of VHA from VA's National Registry of Women Veterans. MEASUREMENTS: Assessments of perceptions of VHA care, background characteristics, and health service use. RESULTS: Perceptions of VHA care were most positive regarding facility/physical environment characteristics and physician skill and sensitivity and least positive regarding the availability of needed services and logistics of receiving VHA care (M=0.05 and M=-0.10; M=-0.23 and M=-0.25, respectively). The most salient barrier to the use of VHA care was problems related to ease of use. Moreover, each of the barriers constructs contributed unique variance in VHA health care use above and beyond background characteristics known to differentiate current users from former VHA users (Odds ratio [OR]=4.03 for availability of services; OR=2.63 for physician sensitivity and skill: OR=2.70 for logistics of care; OR=2.30 for facility/physical environment). Few differences in barriers to care and their association with VHA health care use emerged for women with and without service-connected disabilities. CONCLUSIONS: Findings highlight several domains in which VHA decisionmakers can intervene to enhance the care available to women veterans and point to a number of areas for further investigation.

Gender and trauma as predictors of military attrition: a study of Marine Corps recruits.

Recent studies have shown high rates of premilitary trauma exposure among U.S. military enlistees. Given the association of trauma with later stressor vulnerability, it is important to examine the role of premilitary stress and trauma in adaptation to the stress of recruit training. U.S. Marine Corps recruits (N = 1,530) were surveyed for premilitary histories of interpersonal trauma to examine the relationship between premilitary trauma and attrition from recruit training. The majority of the recruits (47.5% of men and 68.1% of women) reported experiencing at least one interpersonal trauma before entering the Marine Corps. Individuals with a history of interpersonal trauma were at significantly greater risk for attrition; they were 1.5 times more likely to drop out of recruit training than were individuals without a trauma history. These findings suggest that developing interventions to bolster recruits' coping skills may improve adaptation to the recruit training environment and thus decrease attrition.

The course of PTSD symptoms among Gulf War veterans: a growth mixture modeling approach.

Relatively little is known about the course of PTSD symptoms over time following trauma exposure. Accordingly, this study utilized a specialized structural equation modeling approach, growth mixture modeling, to examine the trajectory of PTSD symptoms across three time points in a sample of Gulf War veterans (n at Time 1 = 2,949, n at Time 2 = 2,313, and n at Time 3 = 1,327). Results were most consistent with a two-group model suggesting that the course of PTSD symptoms following the Gulf War was best characterized by two distinct growth curves: (1) low levels of PTSD symptoms with little increase over time and (2) higher levels of initial symptoms with a significant increase over time. Thus, it appears that response to Gulf War experiences is not homogeneous, and that a subset of individuals may experience relatively more PTSD symptoms over time. In addition, men, Whites, those reporting more education, and those reporting less combat exposure had a significantly higher probability of being classified into the less symptomatic group.

An increased capacity for adrenal DHEA release is associated with decreased avoidance and negative mood symptoms in women with PTSD.

We recently found increased adrenal cortisol responses to adrenocorticotropic hormone (ACTH)1-24 and increased pituitary ACTH and adrenal cortisol responses to corticotropin-releasing factor in premenopausal women with chronic post-traumatic stress disorder (PTSD) compared to healthy nontraumatized subjects. This pattern of hypothalamic-pituitary-adrenal axis (HPA) hyper-reactivity has been previously seen in healthy individuals treated with the antiglucocorticoid mifepristone. We therefore investigated whether endogenous plasma levels of antiglucocorticoids such as dehydroepiandrosteroine (DHEA) and progesterone were increased in premenopausal women with PTSD at baseline or in response to adrenal activation by ACTH1-24. The study revealed that DHEA responses to 250 microg ACTH1-24 were increased in 13 PTSD subjects compared to 13 healthy nontraumatized subjects, while DHEA levels were generally increased in the PTSD subjects compared to seven healthy traumatized subjects. Cortisol responses to ACTH1-24 were also higher in the women with PTSD, while progesterone levels and responses were not different among the three groups. In addition, among the PTSD subjects, the peak change in DHEA in response to ACTH1-24 was negatively correlated with the total Clinician Administered PTSD Scale score, while the peak DHEA to cortisol ratio was inversely associated with negative mood symptoms measured by the Profile of Mood States scale. This work suggests that an increased capacity for DHEA release in response to extreme adrenal activation may influence the pattern of HPA axis adaptation to extreme stress, as well as mitigate the severity of PTSD and negative mood symptoms in premenopausal women with PTSD.

Use of VA health care services by women veterans: findings from a national sample.

The Department of Veterans Affairs (VA) has a Congressional mandate but few empirical data on which to design and improve national health care services for women. We examined characteristics associated with women's current, former and non-use of the VA health care system. The study included 1,500 female veterans sampled from the Department of Veterans Affairs National Registry of Women Veterans. Women completed a 45-minute telephone survey assessing multiple domains of functional status and health service use. Using multivariate logistic regression, use of VA health care was associated with older age, more education, not being married, lower rates of insurance coverage, and poorer physical and psychological health. Women who were former users of VA health care were more likely to be ethnic minorities, have children, served less time in the military, had higher rates of insurance coverage and better physical and psychological health than current users. Prominent military experiences (e.g., service in a war-zone, exposure to trauma) were associated with former use and never using the VA health care system. Women who use VA health care are at greater economic, social, and health risk than nonusers, factors that have personal implications for the veteran as well as cost and service implications for VA. Additional research is needed to better understand the role of military experiences in women veterans' choice of health care.

A high risk twin study of combat-related PTSD comorbidity.

Combat-related posttraumatic stress disorder (PTSD) is highly comorbid with other mental disorders. However, the nature of the relationship between PTSD and other mental disorders remains unclear. A discordant high-risk twin design was used on data from a sub-sample of the male-male twin pair members of the Vietnam Era Twin Registry to examine whether patterns of comorbidity are consistent with a psychopathological response to combat exposure or reflect familial vulnerability to psychopathology. Mental disorders were assessed via the Mental Health Diagnostic Interview Schedule Version III - Revised. Discordant monozygotic within-pair comparisons revealed that PTSD probands had higher symptom counts and diagnostic prevalences of mood and anxiety disorders than their non-combat exposed co-twins. Monozygotic co-twins of PTSD probands had significantly more mood disorder symptoms than monozygotic co-twins of combat controls or dizygotic co-twins of veterans with PTSD. These findings suggest that a) major depression, generalized anxiety disorder and panic disorder are part of a post-combat response syndrome; b) a shared familial vulnerability also contributes to the association between PTSD and major depression, PTSD and dysthymia, and c) this shared vulnerability is mediated by genetic factors.
