Abstract
BACKGROUND In the UK military, adjustment disorder (AjD) is reported as one of the most diagnosed mental disorders, alongside depression, in personnel presenting to mental health services. Despite this, little is understood about what may predict AjD, common treatment or outcomes for this population. AIM The systematic review aimed to summarise existing research for AjD in Armed Forces (AF) populations, including prevalence and risk factors, and to outline clinical and occupational outcomes. METHOD A literature search was conducted in December 2020 to identify research that investigated AjD within an AF population (serving or veteran) following the PRISMA guidelines. RESULTS Eighty-three studies were included in the review. The AjD prevalence estimates in AF populations with a mental disorder was considerably higher for serving AF personnel (34.9%) compared to veterans (12.8%). Childhood adversities were identified as a risk factor for AjD. AjD was found to increase the risk of suicidal ideation, with one study reporting a risk ratio of 4.70 (95% Confidence Interval: 3.50-6.20). Talking therapies were the most common treatment for AjD, however none reported on treatment effectiveness. CONCLUSION This review found that AjD was commonly reported across international AF. Despite heterogeneity in the results, the review identifies several literature gaps.

Abstract
Background: The UK Armed Forces (UKAF) have a substantial manning deficit as more personnel leave than join. This article identified pre-service, military, and mental health factors giving rise to leaving the UKAF and estimated the contributions to leaving of those factors which are potentially amenable to modification. Methods: This study utilized data from a three-phase cohort study (2004-2006, 2007-2009 and 2014-2016), commencing while respondents were serving in the UKAF (n = 10,836; 6,046 (55.8%) had left service). Associations between leaving the services and socio-demographics, military career and experiences, and mental health were determined using Cox regression. Contribution to leaving was based on population attributable fractions (PAF) from Cox regression. Analyses were stratified by rank due to the different career structures of Commissioned Officers and enlisted personnel. Results: Leaving the UKAF was associated with joining when older, being a woman with a child/children, Army service, combat role, lower education level, and poor mental health. Factors contributing a significant proportion of leaving among enlisted personnel were joining over the age of 17, history of externalizing behavior, being female, common mental disorders, and alcohol misuse. Among Commissioned Officers only age at joining and sex contributed significant proportions to leaving. Conclusions: The key factors for leaving are education and higher age at recruitment. These are not amenable to intervention, for policy, equity, and legal reasons. Heavy drinking and common mental disorder symptoms may be more amenable to modification and hence reduce rates of leaving the UKAF. Women are more likely to leave due to childbearing.

Abstract
BACKGROUND Fitness to undertake operational deployment is a key requirement of military service. AIM To assess individual deployment fitness at a single point from one month to eight years following discharge from mental healthcare. METHOD Survival analyses assessed levels of deployability; the predictive effects of key covariates upon time to being classified as non-deployable were examined using univariate and multivariate Cox proportional hazards regression procedures. RESULTS A total of 1405 individuals provided study data. 437 individuals (31.1%) were non-deployable or discharged from service during follow-up. 17.2% were non-deployable in the first year following mental healthcare; the proportion did not rise above this level until year seven when it was 19.1% and then 30.6% in year eight. Risk factors for being classified as non-deployable were female sex, receipt of intermediate duration therapy, management by the multidisciplinary team and previous referral to mental health services. Previous deployment was significantly associated with reduced risk. Overall, the levels of non-deployability appeared to be no higher than those found among the wider military services. CONCLUSION Non-deployable status among mental healthcare recipients was broadly similar to that found among the wider UK military; risk factors for non-deployability could be amenable to targeted relapse prevention measures.

Abstract
OBJECTIVE Mental disorders are common in military organizations, and these frequently lead to functional impairments that can interfere with duties and lead to costly attrition. In Canada, the military mental health system has received heavy investment to improve occupational outcomes. We investigated military occupational outcomes of diagnosed mental disorders in a cohort of 30,513 personnel who deployed on the Afghanistan mission. METHODS Cohort members were military personnel who deployed on the Afghanistan mission from 2001 to 2008. Mental disorder diagnoses and their attribution to the Afghanistan mission were ascertained via medical records in a stratified random sample (n = 2014). Career-limiting medical conditions (that is, condition-associated restrictions that reliably lead to medically related attrition) were determined using administrative data. Outcomes were assessed from first Afghanistan-related deployment return. RESULTS At 5 years of follow-up, the Kaplan-Meier estimated cumulative fraction with career-limiting medical conditions was 40.9% (95% confidence interval [CI] 35.5 to 46.4) among individuals with Afghanistan service-related mental disorders (ARMD), 23.6% (CI 15.5 to 31.8) with other mental disorders, and 11.1% (CI 8.9 to 13.3) without mental disorders. The adjusted Cox regression hazard ratios for career-limiting medical condition risk were 4.89 (CI 3.85 to 6.23) among individuals with ARMD and 2.31 (CI 1.48 to 3.60) with other mental disorders, relative to those without mental disorders. CONCLUSIONS Notwithstanding the Canadian military's mental health system investments, mental disorders (particularly ARMD) still led to a high risk of adverse military occupational outcomes. Such investments have intrinsic value but may not translate into reduced medically related attrition without improvements in prevention and treatment effectiveness.

Abstract
OBJECTIVE Mental disorders in military personnel result in high rates of attrition. Military organisations have strengthened their mental health systems and attempted to overcome barriers to care in order to see better outcomes. This study investigated the roles of mental health services renewal and delay to care in Canadian Armed Forces (CAF) personnel diagnosed with mental disorders. DESIGN Administrative data were used to identify a retrospective cohort of 30,513 CAF personnel who deployed in support of the mission in Afghanistan. Study participants included 508 individuals with a mental disorder diagnosis identified from CAF medical records of a weighted, stratified random sample of 2014 individuals selected from the study cohort. Weighted Cox proportional hazards regression assessed the association of diagnosis era and delay to care with the outcome, after controlling for a broad range of potential confounders (eg, disorder severity, comorbidity). Taylor series linearisation methods and sample design weights were applied in generating descriptive and regression analysis statistics. PRIMARY OUTCOME The outcome was release from military service for medical reasons, assessed using administrative data for the 508 individuals with a mental disorder diagnosis. RESULTS 17.5% (95% CI 16.0% to 19.0%) of the cohort had a mental disorder diagnosis after an Afghanistan-related deployment, of which 21.3% (95% CI 17.2% to 25.5%) had a medical release over a median follow-up of 3.5 years. Medical release risk was elevated for individuals diagnosed before 30 April 2008 relative to those with recent diagnoses (adjusted HR (aHR)=1.77 (95% CI 1.01 to 3.11)) and for individuals with a long delay to care (>21 months after return) relative to those with intermediate delays (8-21 months, aHR 2.47=(95% CI 1.28 to 4.76)). CONCLUSIONS Mental health services renewal in the CAF was associated with a better occupational outcome for those diagnosed with mental disorders. Longer delays to care were associated with a less favourable outcome.

Abstract
INTRODUCTION UK military research suggests that there is a significant link between current psychological symptoms, mental health stigmatisation and perceived barriers to care (stigma/BTC). Few studies have explored the construct of stigma/BTC in depth amongst deployed UK military personnel. METHOD Three survey datasets containing a stigma/BTC scale obtained during UK deployments to Iraq and Afghanistan were combined (n=3405 personnel). Principal component analysis was used to identify the key components of stigma/BTC. The relationship between psychological symptoms, the stigma/BTC components and help seeking were examined. RESULTS Two components were identified: 'potential loss of personal military credibility and trust' (stigma Component 1, five items, 49.4% total model variance) and 'negative perceptions of mental health services and barriers to help seeking' (Component 2, six items, 11.2% total model variance). Component 1 was endorsed by 37.8% and Component 2 by 9.4% of personnel. Component 1 was associated with both assessed and subjective mental health, medical appointments and admission to hospital. Stigma Component 2 was associated with subjective and assessed mental health but not with medical appointments. Neither component was associated with help-seeking for subjective psycho-social problems. CONCLUSIONS Potential loss of credibility and trust appeared to be associated with help-seeking for medical reasons but not for help-seeking for subjective psychosocial problems. Those experiencing psychological symptoms appeared to minimise the effects of stigma by seeking out a socially acceptable route into care, such as the medical consultation, whereas those who experienced a subjective mental health problem appeared willing to seek help from any source.

Abstract
BACKGROUND There is concern surrounding the psychological health and uptake of treatment services among veterans of the UK Armed Forces. METHOD Data from a cross-sectional, nationally representative sample were used to compare health outcomes and treatment seeking among 257 post-national service veterans aged 16-64 years and 504 age and sex frequency-matched non-veterans living in the community in England. Early leavers (<4 years service) were compared with longer serving veterans. RESULTS Male veterans reported more childhood adversity and were more likely to have experienced a major trauma in adulthood than non-veterans. There was no association between any measure of mental health and veteran status in males, except reporting more violent behaviours [adjusted odds ratio (aOR) 1.44, 95% confidence interval (CI) 1.01-2.06]. In females, a significant association was found between veteran status and ever having suicidal thoughts (aOR 2.82, 95% CI 1.13-7.03). No differences in treatment-seeking behaviour were identified between veterans and non-veterans with any mental disorder. Early service leavers were more likely to be heavy drinkers (aOR 4.16, 95% CI 1.08-16.00), to have had suicidal thoughts (aOR 2.37, 95% CI 1.21-4.66) and to have self-harmed (aOR 12.36, 95% CI 1.61-94.68) than longer serving veterans. CONCLUSIONS The findings of this study do not suggest that being a veteran is associated with adversity in terms of mental health, social disadvantage or reluctance to seek treatment compared with the general population. Some evidence implies that early service leavers may experience more mental health problems than longer-serving veterans.
