The mental health of the UK Armed Forces: where facts meet fiction

Impact of amyloid PET in the clinical care of veterans in a tertiary memory disorders clinic

Introduction

We aimed to characterize the clinical impact of amyloid PET (APET) in a veteran population with cognitive decline by comparing differences in management between those who did and did not have an APET.

Methods

This was a retrospective observational study. Poisson regressions and logistic regression were used for comparisons.

Results

Out of 565 veterans, 197 underwent APET; positivity rate was 36.55%. Having an APET was associated with longer follow-up, and increased diagnostic variability; it was not associated with number of additional studies, cholinesterase inhibitors prescription, or referrals to research. A positive APET was associated with less diagnostic variability, fewer additional tests, greater cholinesterase inhibitor prescriptions, and more research referrals.

Discussion

In a medically complex, real-world population, APET yielded lower positivity rates and was not associated with classical clinical utility variables when comparing patients with and without an APET. APET may be used more to "rule out" rather than to confirm Alzheimer's disease.

Highlights

Amyloid PET was associated with longer follow-up, and higher diagnostic variability.No association was seen with cholinesterase inhibitors prescription, or referrals to research.In complex patients, expected amyloid PET positivity rates are lower than previously described.Amyloid PETs were used to "rule out" AD than to confirm the diagnosis of AD.

Dementia in veterans and non-veterans in England: a cross-sectional survey

BACKGROUND

Concerns have been raised that military veterans are at greater risk of dementia due to increased rates of depression, post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI) found in this population. The prevalence of dementia in English veterans and whether this is different to non-veterans, however, are currently unknown.

AIMS

To study the risk of dementia in the English veteran population, we aimed to calculate the prevalence of dementia in a group of veterans and compare this with a similar group, with no history of military service.

METHODS

Male veterans and non-veterans aged over 64 years old were identified from the 2007 Adult Psychiatric Morbidity Survey, a national survey of community-dwelling adults in England. This survey was conducted via face-to-face interviews and incorporated questions on previous military service. Dementia was screened by using the modified Telephone Interview of Cognitive Status (TICS-M).

RESULTS

A total of 496 male veterans and 294 non-veterans were identified. TICS-M scores indicated possible dementia in 24% of veterans and 26% non-veterans; after adjusting for age, the odds of possible dementia was significantly lower in veterans than non-veterans (adjusted OR 0.56; 95% CI 0.38-0.84, P < 0.01).

CONCLUSIONS

English male veterans were less likely to have dementia than similar male non-veterans. This study did not find any evidence to support the view that dementia is more common in veterans than non-veterans.

Remote Access Therapy for Veterans With Psychological Problems: Current State of the Art

INTRODUCTION

The past decade has seen both an increase in use and research into ways in which psychological therapy might be delivered remotely. Remote access therapy uses technology to deliver talking therapies. It is important to understand how remote technologies are being used as part of the therapeutic process and consider what effect this has on the success of therapeutic interventions. This review discusses what is currently known about the use of remote access therapy with a veteran population. Moreover, the review summarizes potential benefits and barriers to conducting therapy remotely.

MATERIALS AND METHODS

This review was conducted to explore the use of remote access therapies with veterans. All available literature identified for this review focused on veteran cohorts from the US and UK. To meet search criteria, studies had to include veteran participants engaging with any form of talking therapy delivered remotely. A total of 15 studies met the inclusion criteria: two from the UK and 13 from the US. Searches were carried out during June and July 2019.

RESULTS

A number of potential benefits to remote therapy delivery were observed in the research reviewed, including improved accessibility to therapy for people living in remote locations (providing infrastructure existed to facilitate the remote access technologies), increased flexibility of timing, and being able to undergo therapy alongside other life commitments. The studies also suggested that those involved in remote therapy found the technology accessible and easy to operate. Digital technologies could generally be relied upon and although there were some technical difficulties reported that these were generally not seen as a barrier to the use of remote technologies as a whole. Some limitations to using remote therapies were observed, such as the acceptability of remote therapy, particularly in the UK, and the willingness of practitioners to engage with digital technologies to facilitate remote therapy. There was also caution raised that the apparent cost effectiveness of delivering therapy remotely needs to be further investigated, particularly in relation to costs involved in enabling remote access technologies in locations where poor infrastructure exists.

CONCLUSIONS

Overall, studies reported largely positive outcomes for veterans undergoing remote access therapy and in general participants did not find the therapeutic process compromised by remote delivery. Studies showed that remote access therapy is being conducted successfully in both the US and UK. There is, however, a need for more research into the use of remote access therapies to treat a wider range of psychological difficulties in veterans.

A Cross-Sectional Study of the Relationship between Previous Military Experience and Mental Health Disorders in Currently Serving Public Safety Personnel in Canada

OBJECTIVE

There is an increased incidence of some mental health disorders such as post-traumatic stress disorder (PTSD) in some members of the military and in some public safety personnel (PSP) such as firefighters, police officers, paramedics, and dispatchers. Upon retirement from the armed forces, many individuals go on to second careers as PSP. Individuals with prior military experience may be at even greater risk than nonveterans for developing mental health disorders. The present study was designed to examine the relationship between prior military service and symptoms of mental health disorders in PSP.

METHODS

This is a cross-sectional, observational study. Data for this study were collected from an anonymous, web-based, self-report survey of PSP in Canada. Invitations to participate were sent to PSP via their professional organizations. Indications of mental disorder(s) and symptom severity were assessed using well-validated self-report screening measures.

RESULTS

Of the survey respondents who provided this information, 631 (6.8%) had prior armed forces experience; however, not all responses were complete. Ex-military PSP reported significantly more exposure to traumatic events and were approximately 1.5 times more likely to screen positive for indications of PTSD, mood, anxiety, or acute stress disorders and to have contemplated suicide than those without prior armed forces experience.

CONCLUSIONS

In our study, individuals in PSP with prior service experience in the armed forces were more likely to screen positive for indicators of some mental health disorders. Accordingly, mental health practitioners should inquire about previous service in the armed forces when screening, assessing, and treating PSP.

Risk and protective factors for post-traumatic stress among New Zealand military personnel: A cross sectional study

Background

Post-traumatic stress (PTS) is prevalent among military personnel. Knowledge of the risk and protective factors associated with PTS in this population may assist with identifying personnel who would benefit from increased or targeted support.

Aims

To examine factors associated with PTS among New Zealand military personnel.

Methods

For this cross-sectional study, currently serving and retired military personnel were invited to complete a questionnaire. The questionnaire included a measure of PTS (the Military Post-traumatic Stress Disorder Checklist; PCL-M), where scores ≥30 indicate the experience of significant PTS symptoms and scores ≥45 indicate a presumptive clinical diagnosis of post-traumatic stress. Potential risk and protective factors associated with PTS were examined using logistic regression modelling.

Results

1817 military personnel completed the questionnaire. PCL-M scores were ≥30 for 549 (30%) participants and ≥45 for 179 (10%) participants. Factors associated with higher PCL-M scores were trauma exposure, older age, male sex, and Māori ethnicity. Factors associated with lower PCL-M scores were greater length of service, psychological flexibility, and better quality sleep.

Conclusions

PTS was found to be prevalent among New Zealand military personnel. The experience of trauma was strongly associated with PTS. However, factors such as psychological flexibility (the ability to adapt to changes in circumstances) and good sleep were protective, suggesting that these factors could be key targets for interventions designed to reduce PTS among military personnel in New Zealand.

Effect of group reminiscence therapy on depression and perceived meaning of life of veterans diagnosed with dementia at veteran homes

Most senior veterans who live in veteran homes in Taiwan have few interpersonal relationships. Aging is often accompanied by solitude and illness, which causes senior veterans to doubt the meaning of life and to lose confidence in the value of life. This study tested the effectiveness of a group reminiscence therapy protocol on the depression and meaning of life among elderly institutionalized veterans. A quasi-experimental design was applied. A convenience sample of older adults was drawn from two veteran homes in southern Taiwan. Participants were assigned to intervention or control groups based on the veterans' homes they attended. The participants in the intervention group carried out group reminiscence therapy for 8 weeks in addition to their daily activities. The participants in the comparison group maintained their daily activities. Both groups were evaluated using the GDS-SF and MLS scale including two aspects of depression mood and meaning of life in weeks 1 and 8. The overall life satisfaction increased significantly over time for the intervention group compared to the comparison group from week 1 to week 8. The group reminiscence therapy programs showed promising effects in improving the depression and meaning of life of older veterans living in veteran homes.

Caring for veterans in US civilian primary care: qualitative interviews with primary care providers

BACKGROUND

Non-VA health care providers in the USA have been called upon to screen patients for veteran status as a means to better identify military-related health sequelae. Despite this recognized need, many service members are still not being asked about veteran status.

OBJECTIVE

The purpose of this research was to qualitatively assess, from non-VA primary care providers' point-of-view, barriers to providing care to veterans, the training providers perceive as most useful and the tools and translational processes they think would be most valuable in increasing military cultural competency.

METHODS

Semi-structured qualitative interviews, with non-VA primary care providers (N = 10) as part of a larger quantitative study of primary care providers' attitudes around veteran care. Interviews asked about providers' approach to addressing veteran status in their practice and their thoughts on how to address the needs of this population. Qualitative data were analyzed using a thematic content analysis approach.

RESULTS

Three major themes were identified: (i) barriers to caring for patients who are identified as veterans, (ii) thoughts on tools that might help better identify and screen veteran patients and (iii) thoughts on translating and implementing new care processes for veteran patients into everyday practice.

CONCLUSIONS

Our study identified barriers related to non-VA providers' ability to care for veterans among their patients and possible mechanisms for improving recognition of veterans in civilian health care settings. There is a need for further research to understand how assessment, screening and follow up care for veteran patients is best implemented into civilian primary care settings.

Adapting CBT to treat depression in Armed Forces Veterans: qualitative study

BACKGROUND

The principles of the Armed Forces Covenant state that Armed Forces Veterans should be at no disadvantage resulting from their service compared with a general adult population. However, despite being at increased risk of experiencing common mental health difficulties, evidence indicates that 82% of Armed Forces Veterans receive no treatment, compared with 63% of the general adult population.

AIM

To gain a better appreciation of factors that inform the type of adaptations to cognitive behavioural therapy (CBT) interventions for depression and mainstream service promotion materials to enhance acceptability for Armed Forces Veterans.

METHOD

This is a qualitative study employing a focus group of 12 participants to examine the main impacts of depression on Armed Forces Veterans alongside attitudes towards terminology and visual imagery. Thematic analysis was used to identify themes and sub-themes with rigour established through two researchers independently developing thematic maps to inform a final agreed thematic map.

RESULTS

A behavioural activation intervention supporting re-engagement with activities to overcome depression had good levels of acceptability when adapted to reflect an Armed Forces culture. Preferences regarding terminology commonly used within CBT adapted for Armed Forces Veterans were identified. Concerns were expressed with respect to using imagery that emphasized physical rather than mental health difficulties.

CONCLUSIONS

There is the need to consider the Armed Forces community as a specific institutional culture when developing CBT approaches with potential to enhance engagement, completion and recovery rates. Results have potential to inform the practice of CBT with Armed Forces Veterans and future research.

Military psychologists and cultural competence: exploring implications for the manifestation and treatment of psychological trauma in the British armed forces

This paper considers the manifestation and treatment of psychological trauma in the military. The article describes how military psychologists conceptualise psychological trauma within the culture of the Armed Forces (AF), which is reflected in the process of acquiring what has been referred to as cultural competency. Psychologists in this context acquire an understanding of the manner in which the psychological and organisational systems and culture of the military affect the presentation of psychological trauma, including post-traumatic stress disorder (PTSD). The paper outlines core psychological features of military life, including some of the ways in which the AF functions effectively as an adaptable fighting force. This highlights, for example, the potential for stigma within and between military personnel who experience mental health difficulties. The article proceeds to examine aspects of help-seeking in military mental healthcare, how symptoms can present at different stages in a deployment process, and the consequences that such problems can cause for military conduct and performance. Psychological care in the military is structured within an occupational mental health ethos, in which psychologists fulfil a range of clinical, organisational and leadership roles. These dynamics are explored with examples of care pathways and clarity on evidence-based interventions for trauma and PTSD in those experiencing military-related psychological injuries. Two vignettes are then offered to illustrate how some of these interventions can be used psychotherapeutically in addressing symptoms pertaining to hyperarousal, hypervigilance, guilt and shame.

Adjustment profiles of Yom Kippur war veterans seeking delayed help from the IDF

The most common stress reactions following combat are post-traumatic stress reactions. These responses have a great impact on quality-of-life and can damage victims' personal, familial, and social functioning. However, of the people who develop PTSD, only a few request psychological help. The first aim of the research was, therefore, to examine the long-term adjustment patterns of Yom Kippur War veterans who sought help only after a period of more than 30 years. The second aim was to classify the participants according to a common symptom profile. The participant sample consisted of 195 Yom Kippur War veterans who went through a process of assessment and evaluation via intake interviews conducted between 2006 and 2012, when they came to the Combat Stress Reaction (CSR) unit. Data were collected from the participants' files. The findings indicated that, by the time they arrived at the CSR Unit, 90.8% of the participants were experiencing PTSD. The findings support the argument that delayed onset of PTSD without a background history of symptoms is rare, and indicate that most people who seek help report that their low-level symptoms intensified over the years until these symptoms developed into clinically meaningful PTSD.

Military psychological trauma and therapy: a review of EMDR treatment and supervision in the UK Ministry of Defence

Psychological injury has been associated with military service, and this can result in a variety of mental health symptoms and disorders. A range of barriers to help-seeking have been identified in the military and mental health services have sought to address such factors through effective and efficient care and consultation. The use of eye movement desensitisation and reprocessing forms part of a repertoire of trauma-focused therapies within the UK's Armed Forces. This article will outline the application of this approach within the British military, along with the role of specialist clinical supervision in treating those affected by operational trauma.

Mental health outcomes at the end of the British involvement in the Iraq and Afghanistan conflicts: a cohort study

BACKGROUND

Little is known about the prevalence of mental health outcomes in UK personnel at the end of the British involvement in the Iraq and Afghanistan conflicts.AimsWe examined the prevalence of mental disorders and alcohol misuse, whether this differed between serving and ex-serving regular personnel and by deployment status.

METHOD

This is the third phase of a military cohort study (2014-2016; n = 8093). The sample was based on participants from previous phases (2004-2006 and 2007-2009) and a new randomly selected sample of those who had joined the UK armed forces since 2009.

RESULTS

The prevalence was 6.2% for probable post-traumatic stress disorder, 21.9% for common mental disorders and 10.0% for alcohol misuse. Deployment to Iraq or Afghanistan and a combat role during deployment were associated with significantly worse mental health outcomes and alcohol misuse in ex-serving regular personnel but not in currently serving regular personnel.

CONCLUSIONS

The findings highlight an increasing prevalence of post-traumatic stress disorder and a lowering prevalence of alcohol misuse compared with our previous findings and stresses the importance of continued surveillance during service and beyond.

A systematic review of wellbeing in children: a comparison of military and civilian families

BACKGROUND

Children in military families have uniquely different childhood experiences compared to their civilian peers, including a parent in employment and a stable familial income, frequent relocations, indirect exposure to and awareness of conflict, and extended separation from parents or siblings due to deployment. However, whether children from military families have poorer wellbeing than non-military connected children is not well understood.

METHOD

We conducted a systematic review to explore the relationship between military family membership (e.g. parent or sibling in the military) and child wellbeing compared to non-military connected controls. Searches for this review were conducted in September 2016 and then updated in February 2018.

RESULTS

Nine studies were identified, eight were cross-sectional. All studies utilised self-report measures administered in US school settings. On the whole, military connected youth were not found to have poorer wellbeing than civilian children, although those with deployed parents and older military connected children were at greater risk of some adjustment difficulties (e.g. substance use, externalising behaviour). Although only assessed in two studies, having a sibling in the military and experiencing sibling deployment was statistically significantly associated with substance use and depressive symptoms.

CONCLUSIONS

This study is unique in its direct comparison of military and non-military connected youth. Our results highlight the need to examine the impact of military service in siblings and other close relatives on child wellbeing. Given the adverse impact of poor mental health on child functioning, additional research is needed ensure appropriate, evidence-based interventions are available for youth in military families.

Dementia, post-traumatic stress disorder and major depressive disorder: a review of the mental health risk factors for dementia in the military veteran population

BACKGROUND

Dementia is currently incurable, irreversible and a major cause of disability for the world's older population. The association between mental health difficulties, such as post-traumatic stress disorder (PTSD) and major depressive disorder (MDD), and dementia has a long history within the civilian population. Despite the increased importance of this link within the military veteran population, who suffer a greater propensity of mental health difficulties and consist largely of over 65s, attention is only recently being paid to the salience of such an association for this group. This paper aims to explore the relationship between PTSD and MDD with dementia within the military veteran population.

METHOD

A systematic review was conducted on articles from 1990 to July 2016 on MEDLINE, EMBASE, EBSCO and Web of Science electronic databases with an update conducted in February 2017.

RESULTS

Six empirical studies were identified from the review, the majority of which originated from the USA. Five of the studies asserted that veterans with a diagnosis of either PTSD or MDD are at a significantly greater risk of developing dementia than 'healthy' controls. The final study, conducted in Australia, found only a small, but non-significant, correlation between earlier MDD and future dementia, but no concurrent correlation.

CONCLUSIONS

While causality cannot be determined, it is likely that PTSD and depressive disorders are related to an increased risk of dementia in military veterans. Potential pathological explanations and risk factors are reviewed and the clinical and neuroscience implications of these findings are explored.

Can scuba diving offer therapeutic benefit to military veterans experiencing physical and psychological injuries as a result of combat? A service evaluation of Deptherapy UK

Purpose: To explore the effectiveness of scuba diving in providing therapeutic and rehabilitative benefit to ex-service personnel who have experienced traumatic physical and/or psychological injuries resulting from combat.Methods: This study took the form of a service evaluation of Deptherapy, a UK-based niche charity offering support to military veterans who have experienced life-changing injuries. Deptherapy provides scuba diving qualifications, consisting of theory and practical diving experience, to participants alongside a Peer Support Buddy scheme that provides continuing support to servicemen involved with the charity. A total of 15 male veterans were invited to take part in the study. The methodology comprised retrospective and current quantitative measures of mental well-being and functional ability, utilising the General Health Questionnaire-28, and subsequent semi-structured interviews with participants, their families and health professionals.Results: Participants reported an improvement in levels of anxiety, depression and social functioning, and a reduction in insomnia, following their involvement in organised scuba diving activities. There was a mean average difference of 14.3 points improvement on the General Health Questionnaire-28 scale variants between prior interaction with Deptherapy and current perceptions following engagement with the programme. The positive perceptions, as indicated from the semi-structured interviews, were more pronounced in those whose injuries were predominantly psychological, rather than physical.Conclusion: Scuba diving can offer significant therapeutic benefits, particularly for ex-military amputees experiencing co-morbid anxiety and/or chronic psychological adjustment disorders, notably in terms of improvements in social dysfunction and symptomology of depression.Implications for Rehabilitation Scuba Diving as a TherapyMilitary combat can result in devastating, chronic physical and/or psychological injury.Current research suggests that a combination of medical and psychological therapy may prove to be the most beneficial for military veterans.Scuba diving has the potential to benefit injured veterans due the requirement of complete focus and the feeling of weightlessness when underwater.This article evaluates whether scuba diving is an effective physical and psychological therapy through GHQ-28 analysis and veteran interviews.Scuba diving benefited injured veterans in terms of chronic pain relief and depression symptoms alleviation.

Is prevention better than cure? A systematic review of the effectiveness of well-being interventions for military personnel adjusting to civilian life

Exposure to stressful and potentially traumatic experiences is a risk for military personnel and for some this may increase susceptibility to reduced well-being. The aim of this systematic review was to examine the effectiveness of interventions to promote the well-being of military personnel adjusting to civilian life. Electronic databases were searched including MEDLINE, Embase, HMIC, PsycINFO, Pilots and CINAHL. Twelve articles, all conducted in the USA, were included in the review. Articles were synthesised narratively and assessed for bias against established criteria. The studies evaluated the effectiveness of interventions for current and former military personnel. The interventions included expressive writing, anger management, cognitive training, psycho-education, and techniques to promote relaxation, connection in relationships and resilience. Interventions had some significant positive effects mostly for veterans adjusting to civilian life and other family members. There was much heterogeneity in the design and the outcome measures used in the studies reviewed. The review highlights the need for future robust trials examining the effectiveness of well-being interventions in military groups with diverse characteristics; in addition qualitative research to explore a conceptualisation of well-being for this group and the acceptability of interventions which may be perceived as treatment. The results of the review will be of interest to a number of stakeholders in military, public health and mental health settings. PROSPERO Registration number: CRD42015026341.

What's so special about military veterans?

The mental health of military veterans has been, and continues to be, a topic of heated political and journalistic debate. There is a well-documented impact of conflict upon the mental health of service personnel, and most nations have aimed to provide effective care for individuals who have fought for their country. However, as the three thematic papers in this issue demonstrate, the realities of service-related mental health are rather more complex than they initially appear.

Malingering mental disorders: Clinical assessment

Malingering is the dishonest and intentional production of symptoms. It can cause considerable difficulty as assessment runs counter to normal practice, and it may expose clinicians to testing medicolegal situations. In this first part of a two-article review, we explore types of psychiatric malingering and their occurrence across a range of common and challenging scenarios, discussing presentations that may help delineate true from feigned illness. A framework is provided for undertaking an assessment where malingering is suspected, including recommendations on clinician approach, the use of collateral information, and self-evaluation of biases. The uses, and limitations, of psychometric tests are discussed, including ‘general’, malingering-specific and ‘symptom validity’ scales.

Learning Objectives

• Understand the challenges of determining ‘real’ from ‘malingered’ symptomatology across a range of psychiatric conditions

• Have a rational strategy for approaching a clinical assessment where malingering is suspected

• Appreciate the role and limitations of various psychometric tests that can be used in such assessments

Assessing PTSD in the military: Validation of a scale distributed to Danish soldiers after deployment since 1998

Since 1998, soldiers deployed to war zones with the Danish Defense (≈31,000) have been invited to fill out a questionnaire on post-mission reactions. This provides a unique data source for studying the psychological toll of war. Here, we validate a measure of PTSD-symptoms from the questionnaire. Soldiers from two cohorts deployed to Afghanistan with the International Security Assistance Force (ISAF) in 2009 (ISAF7, N = 334) and 2013 (ISAF15, N = 278) filled out a standard questionnaire (Psychological Reactions following International Missions, PRIM) concerning a range of post-deployment reactions including symptoms of PTSD (PRIM-PTSD). They also filled out a validated measure of PTSD-symptoms in DSM-IV, the PTSD-checklist (PCL). We tested reliability of PRIM-PTSD by estimating Cronbach's alpha, and tested validity by correlating items, clusters, and overall scale with corresponding items in the PCL. Furthermore, we conducted two confirmatory factor analytic models to test the factor structure of PRIM-PTSD, and tested measurement invariance of the selected model. Finally, we established a screening and a clinical cutoff score by application of ROC analysis. We found high internal consistency of the PRIM-PTSD (Cronbach's alpha = 0.88; both cohorts), strong item-item (0.48-0.83), item-cluster (0.43-0.72), cluster-cluster (0.71-0.82) and full-scale (0.86-0.88) correlations between PRIM-PTSD and PCL. The factor analyses showed adequate fit of a one-factor model, which was also found to display strong measurement invariance across cohorts. ROC curve analysis established cutoff scores for screening (sensitivity = 1, specificity = 0.93) and clinical use (sensitivity = 0.71, specificity = 0.98). In conclusion, we find that PRIM-PTSD is a valid measure for assessing PTSD-symptoms in Danish soldiers following deployment.

Prevalence and severity of mental disorders in military personnel: a standardised comparison with civilians

AIMS

Provision and need for mental health services among military personnel are a major concern across nations. Two recent comparisons suggest higher rates of mental disorders in US and UK military personnel compared with civilians. However, these findings may not apply to other nations. Previous studies have focused on the overall effects of military service rather than the separate effects of military service and deployment. This study compared German military personnel with and without a history of deployment to sociodemographically matched civilians regarding prevalence and severity of 12-month DSM-IV mental disorders.

METHOD

1439 deployed soldiers (DS), 779 never deployed soldiers (NS) and 1023 civilians were assessed with an adapted version of the Munich Composite International Diagnostic interview across the same timeframe. Data were weighted using propensity score methodology to assure comparability of the three samples.

RESULTS

Compared with adjusted civilians, the prevalence of any 12-month disorder was lower in NS (OR: 0.7, 95% CI: 0.5-0.99) and did not differ in DS. Significant differences between military personnel and civilians regarding prevalence and severity of individual diagnoses were only apparent for alcohol (DS: OR: 0.3, 95% CI: 0.1-0.6; NS: OR: 0.2, 95% CI: 0.1-0.6) and nicotine dependence (DS: OR: 0.5, 95% CI: 0.3-0.6; NS: OR: 0.5, 95% CI: 0.3-0.7) with lower values in both military samples. Elevated rates of panic/agoraphobia (OR: 2.7, 95% CI: 1.4-5.3) and posttraumatic stress disorder (OR: 3.2, 95% CI: 1.3-8.0) were observed in DS with high combat exposure compared with civilians.

CONCLUSIONS

Rates and severity of mental disorders in the German military are comparable with civilians for internalising and lower for substance use disorders. A higher risk of some disorders is reduced to DS with high combat exposure. This finding has implications for mental health service provision and the need for targeted interventions. Differences to previous US and UK studies that suggest an overall higher prevalence in military personnel might result from divergent study methods, deployment characteristics, military structures and occupational factors. Some of these factors might yield valuable targets to improve military mental health.

Military veterans’ experiences of NHS mental health services

Purpose

A significant minority of veterans have poor mental health outcomes but their needs are not always well managed by the NHS. The purpose of this paper is to explore veterans’ experiences of NHS mental healthcare in Norfolk and Suffolk to identify ways of improving services.

Design/methodology/approach

Interviews were conducted with 30 veterans. Template analysis was undertaken to explore key themes in the interview transcripts.

Findings

Participants were reluctant to seek help but were more likely to engage with a veteran-specific service. Those whose symptoms were military related reported better experiences when accessing treatment that was military sensitive.

Research limitations/implications

This was a local study and the findings do not necessarily reflect the views of the wider veteran community. Most participants who received military sensitive treatment were referred to the study by NHS providers, which could account for their positive feedback.

Social implications

The development of dedicated mental health services may encourage more veterans to seek support, helping to improve patient outcomes. There is a need for further research to determine the effectiveness of dedicated services and identify how they should be deployed.

Originality/value

Where academic interest has generally centred on the aetiology of mental health conditions within the military, this study focussed upon service user experience. The findings contributed to NHS England’s recent decision to extend its network of dedicated services in 12 areas of the country to cover veterans across England from April 2017.

A review of the physiological and psychological health and wellbeing of naval service personnel and the modalities used for monitoring

Naval cohorts rely heavily on personnel to ensure the efficient running of naval organisations. As such, the wellbeing of personnel is essential. In an occupational setting, naval service personnel experience a variety of physiological and psychological stressors. Most naval services arrange annual physical fitness and body composition tests to ensure the physical readiness of personnel. However, these tests only evaluate a small amount of physiological capabilities. Components such as aerobic and strength capabilities are assessed, however, other components of physical fitness such as speed, agility, anaerobic capacity and flexibility are not. In addition to the physical capabilities, personnel are impacted by fatigue, nutrition and psychological stressors such as copping in stressful situations or dealing with time away from family and friends. This review will discuss the physiological and psychological factors that affect personnel's wellbeing. In addition to this, it will also evaluate the methods that are used to assess both physiological and psychological wellbeing.

Norwegian male military veterans show low levels of mental health problems four years after deployment in Afghanistan

BACKGROUND

Deployment of soldiers is associated with considerable rates of mental disorders after redeployment.

AIMS

The aim of this study was to identity prevalence of probable mental disorders and associated factors among male Norwegian soldiers at a mean of 4 years following deployment to Afghanistan in 2001-2011.

METHODS

The retrospective questionnaire-based study invited all Norwegian veterans deployed to Afghanistan from 2001-2011 to participate. The response rate was 59%, but only the 3403 men (47.5%) who completed all items of the four different screening instruments were used to define cases with mental health problems were included. Independent variables covered deployment and post-deployment issues.

RESULTS

The prevalence of subjects with mental health problems was 5.1% (95% CI = 4.4-5.9%) of the sample. Among deployment-related factors, physical and mental problems during deployment were most strongly associated with mental health problems after deployment. Among post-deployment factors high neuroticism and limitations in work, social, and family functions showed the strongest associations. In multivariable analysis, younger age at first deployment (OR = 0.95), neuroticism (OR = 6.40), increased current alcohol intake (OR = 3.08), impaired family function (OR = 1.91), more sleep problems (OR =1.13), and increased negative civilian life events (OR = 1.39) remained significantly associated with probable mental disorders.

CONCLUSIONS

Among male Norwegian veterans from Afghanistan, the prevalence of mental health problems was low, and mainly associated with post-deployment factors. Veterans complaining of mental symptoms should be diagnosed, treated, and examined for other problems of life.

A service evaluation of self-referral to military mental health teams

BACKGROUND

The UK military runs a comprehensive mental health service ordinarily accessed via primary care referrals.

AIMS

To evaluate the feasibility of self-referral to mental health services within a military environment.

METHODS

Three pilot sites were identified; one from each service (Royal Navy, Army, Air Force). Socio-demographic information included age, rank, service and career duration. Clinical data included prior contact with general practitioner (GP), provisional diagnosis and assessment outcome.

RESULTS

Of the 57 self-referrals, 69% (n = 39) had not previously accessed primary care for their current difficulties. After their mental health assessment, 47 (82%) were found to have a formal mental health problem and 41 (72%) were offered a further mental health clinician appointment. The data compared favourably with a large military mental health department that reported 87% of primary care referrals had a formal mental health condition.

CONCLUSIONS

The majority of self-referrals had formal mental health conditions for which they had not previously sought help from primary care; most were offered further clinical input. This supports the view that self-referral may be a useful option to encourage military personnel to seek professional care over and above the usual route of accessing care through their GP.

ATTENTIONAL BIAS TEMPORAL DYNAMICS PREDICT POSTTRAUMATIC STRESS SYMPTOMS: A PROSPECTIVE-LONGITUDINAL STUDY AMONG SOLDIERS

BACKGROUND

Attentional bias (AB) to threat is thought to play a key role in the development and maintenance of posttraumatic stress symptomatology (PTS). Empirical evidence though is inconsistent. Some studies report associations between AB towards, threat and PTS; other studies report associations between AB away from threat and PTS; yet other studies fail to find any association. We propose that prospective-longitudinal study of AB as a dynamic process, expressed from moment to moment in time, may help to understand these mixed findings and the role of AB in PTS.

METHODS

We tested cross-sectional and prospective-longitudinal associations between AB and PTS among German soldiers from pre- to post-deployment in Afghanistan (n = 144). AB to threat and positive emotion stimuli (angry/happy faces) was measured using the dot-probe task. PTS was assessed by the PTSD Checklist. The number of traumatic experiences was assessed using CIDI-traumatic experience lists for military.

RESULTS

We found that AB dynamics (i.e., towards, away, temporal variability) at pre- and post-deployment, with respect to angry and happy faces, predicted higher levels of PTS after deployment as a function of number of intermediate traumatic experiences. Traditional aggregated mean bias scores did not similarly prospectively predict PTS post deployment.

CONCLUSIONS

Findings indicate that AB to emotionally arousing stimuli may play an important function in the development and maintenance of PTS. We argue that mixed and null findings appear to be due to failure to model the within-subject temporal variability in AB expression. Theoretical, empirical, and clinical implications of these findings are discussed.

Prevalence of Past-Year Mental Disorders in the Canadian Armed Forces, 2002-2013

OBJECTIVE

More than 40,000 Canadian Armed Forces (CAF) personnel have deployed in support of the mission in Afghanistan since 2002. Over the same period, the CAF strengthened its mental health system. This article explores the effect of these events on the prevalence of past-year mental disorders over the period 2002-2013.

METHOD

The data sources were 2 highly comparable population-based mental health surveys of CAF Regular Force personnel done in 2002 and 2013 (n = 5155 and 6996, respectively). Data were collected via in-person interviews with Statistics Canada personnel using the World Health Organization's Composite International Diagnostic Interview to assess past-year disorders.

RESULTS

In 2013, 16.5% had 1 or more of the 6 past-year disorders assessed in the survey, with the most common conditions being major depressive episode (MDE), posttraumatic stress disorder (PTSD), and generalized anxiety disorder (GAD), which affected 8.0%, 5.3%, and 4.7%, respectively. The prevalence of PTSD, GAD, and panic disorder has increased significantly since 2002 (adjusted odds ratios from logistic regression models = 2.1, 3.0, and 1.9, respectively), while no change was seen for MDE. The comorbidity of mood and anxiety disorders increased significantly over time, being seen in 27.4% and 41.0% of those with mental disorders in 2002 and 2013, respectively.

CONCLUSION

There has been an increase in the prevalence of PTSD and other anxiety disorders and of the extent of comorbidity of mood and anxiety disorders in CAF personnel over the period 2002-2013.

Mental health of Canadian Armed Forces Veterans: review of population studies

Introduction. The mental health of Canadian Armed Forces (CAF) populations emerged as an important concern in the wake of difficult CAF deployments in the 1990s. This article is the first comprehensive summary of findings from subsequent surveys of mental health and well-being in CAF Veterans, undertaken to inform mental health service renewals by CAF Health Services and Veterans Affairs Canada (VAC). Methods. Epidemiological findings in journal publications and government reports were summarized from four cross-sectional national surveys: a survey of Veterans participating in VAC programs in 1999 and three surveys of health and well-being representative of whole populations of Veterans in 2003, 2010, and 2013. Results. Although most Veterans had good mental health, many had mental health problems that affected functioning, well-being, and service utilization. Recent Veterans had a higher prevalence of mental health problems than the general Canadian population, earlier-era Veterans, and possibly the serving population. There were associations between mental health conditions and difficult adjustment to civilian life, physical health, and multiple socio-demographic factors. Mental health problems were key drivers of disability. Comparisons with other studies were complicated by methodological, era, and cultural differences. Discussion. The survey findings support ongoing multifactorial approaches to optimizing mental health and well-being in CAF Veterans, including strong military-to-civilian transition support and access to effective mental and physical health services. Studies underway of transitioning members and families in the peri-release period of the military-to-civilian transition and longitudinal studies of mental health in Veterans will address important knowledge gaps.

Contribution of the Mission in Afghanistan to the Burden of Past-Year Mental Disorders in Canadian Armed Forces Personnel, 2013

OBJECTIVE

The purpose of this study was to estimate the contribution of the mission in Afghanistan to the burden of mental health problems in the Canadian Armed Forces (CAF).

METHODS

Data were obtained from the 2013 Canadian Forces Mental Health Survey, which assessed mental disorders using the World Health Organization's Composite International Diagnostic Interview. The sample consisted of 6696 Regular Force (RegF) personnel, 3384 of whom had deployed in support of the mission. We estimated the association of past-year mental health problems with Afghanistan deployment status, adjusting for covariates using logistic regression; population attributable fractions (PAFs) were also calculated.

RESULTS

Indication of a past-year mental disorder was identified in 18.4% (95% confidence interval [CI], 17.0% to 19.7%) of Afghanistan deployers compared with 14.6% (95% CI, 13.3% to 15.8%) in others. Afghanistan-related deployments contributed to the burden of a past-year disorder (PAF = 8.7%; 95% CI, 3.0% to 14.2%), with the highest PAFs being seen for panic disorder (34.7%) and posttraumatic stress disorder (32.1%). The PAFs for individual alcohol use disorders and suicide ideation were not different from zero. Child abuse, however, had a much greater PAF for any past-year disorder (28.7%; 95% CI, 23.4% to 33.7%) than did the Afghanistan mission.

CONCLUSIONS

The mission in Afghanistan contributed significantly to the burden of mental disorders in the CAF RegF in 2013. However, the much stronger contribution of child abuse highlights the need for strong military mental health systems, even in peacetime, and the need to target the full range of determinants of mental health in prevention and control efforts.

Research on PTSD prevalence in OEF/OIF Veterans: expanding investigation of demographic variables

BACKGROUND

A series of recent articles has reported on well-designed studies examining base rates of posttraumatic stress disorder (PTSD) screenings within the Operation Enduring Freedom (Afghanistan conflict)/Operation Iraqi Freedom (Iraq conflict) (OEF/OIF) military population. Although these studies have a number of strengths, this line of research points out several key areas in need of further examination.

OBJECTIVE

Many OEF/OIF Veterans do not use available Veterans Affairs (VA) services, especially mental health care. This highlights the need to understand the differences between those who use and do not use the VA, especially as research with pre-OEF/OIF Veterans suggests that these two groups differ in significant ways. The high rates of PTSD-related concerns in non-VA users also points to a need to understand whether-and where-Veterans are seeking care outside the VA and the accessibility of evidence-based, trauma-focused treatments in the community and private sectors. Careful examination of relationship status is also paramount as little research has examined relationship status or other relationship context issues. Social support, especially from a spouse, can buffer the development of PTSD; however, relationship discord has the potential to greatly exacerbate PTSD symptomatology. Furthermore, given the additional risk factors for sexual minority Veterans to be exposed to trauma, the 2011 repeal of the US Military "Don't Ask, Don't Tell" policy, and the emergence of the VA as likely the largest health care provider for sexual minority Veterans, it will be critically important to study the trauma and mental health experiences of this group.

CONCLUSIONS

Studies that examine prevalence rates of PTSD in the returning cohort contribute significantly to our understanding of the US OEF/OIF military population. Further study of PTSD in relation to demographic variables such as VA and non-VA use, relationship status, and sexual orientation will provide rich data that will enhance our ability to develop policy and practice to provide the best care to this population.

What's so special about military veterans?

The mental health of military veterans has been, and continues to be, a topic of heated political and journalistic debate. There is a well-documented impact of conflict upon the mental health of service personnel, and most nations have aimed to provide effective care for individuals who have fought for their country. However, as the three thematic papers in this issue demonstrate, the realities of service-related mental health are rather more complex than they initially appear.

PTSD in the military: special considerations for understanding prevalence, pathophysiology and treatment following deployment

Given the unique context of warzone engagement, which may include chronic threat, multiple and lengthy deployments, and loss, there is a need to understand whether and to what extent knowledge about PTSD derived from studies of civilian trauma exposure is generalizeable to the military. This special issue on PTSD in the military addresses a range of issues and debates related to mental health in military personnel and combat veterans. This article provides an overview of the issues covered in selected contributions that have been assembled for a special volume to consider issues unique to the military. Several leading scholars and military experts have contributed papers regarding: 1) prevalence rates of PTSD and other post-deployment mental health problems in different NATO countries, 2) the search for biomarkers of PTSD and the potential applications of such findings, and 3) prevention and intervention approaches for service members and veterans. The volume includes studies that highlight the divergence in prevalence rates of PTSD and other post-deployment mental health problems across nations and that discuss potential causes and implications. Included studies also provide an overview of research conducted in military or Veteran's Affairs settings, and overarching reviews of military-wide approaches to research, promotion of resilience, and mental health interventions in the Unites States and across NATO and allied ISAF partners.
