The diathesis-stress model in the emergence of major psychiatric disorders during military service.

Existing evidence and the diathesis-stress model hypothesis suggest that stress as an environmental factor may trigger the onset of psychiatric disorders, such as psychosis spectrum disorders, mood disorders, anxiety disorders, in people with an underlying vulnerability. The purpose of this study was to determine the period of time during military service at which symptomatology of clinical significance is more often developed, considering that stress of service and adaptation to its requirements is common to all army recruits. A retrospective file study for the years 2017-2018 was conducted in order to identify male soldiers who were hospitalized in the psychiatric clinic of 414 Athens Military hospital and diagnosed as F20-29, F30-39 and F40-48 according to ICD-10. The number of hospitalizations per clinical diagnosis and the time of onset relatively to the month of military service were examined. A total of 139 cases were screened, 119 of which had disorders falling into the diagnostic categories F20-29, F30-39 and F40-48. 53% of total hospitalizations took place within the first two months of a nine-month military service. It was found that the risk of disorder onset within the first two months of military service was statistically higher (OR=0.210, p=0.001) for a schizophrenic spectrum disorder (F20-29) compared to F30-39 and F40-48 disorders. After adjusting for potential confounders, such as heritability for psychiatric disorders, urbanicity, history of substance use or age, the risk for hospitalization within the first two months continued to be significantly predicted by F20-29 disorder (OR=0.255, p=0.022) compared to other diagnoses. Individuals vulnerable in developing a psychotic disorder appear to have lower stress tolerance and may manifest an earlier disease onset, when exposed to the stress of military service compared to subjects predisposed to develop mood or anxiety disorders. Stress during military service is of major importance for the emergence of the whole psychopathology spectrum, particularly in vulnerable individuals. The development of prevention and early intervention strategies is considered to be of particular importance to conscripts. The findings of the present study are in agreement with the diathesis-stress model and moreover suggest that people who subsequently develop a psychotic spectrum disorder have greater vulnerability to stress exposure.

Burnout Among US Military Behavioral Health Providers.

The present study investigated the prevalence of burnout among US military behavioral health providers (BHPs) and tested a mechanism of developing burnout in a job demands-resources model. Surveys were sent to BHPs working with US military populations globally (T1). Six months after, surveys were collected again at T2. In total, 271 providers completed T1, and 116 completed T2. The job demands-resources model showed that T1 burnout self-efficacy and support predicted T2 burnout and work engagement. T1 job demands predicted T2 burnout. To provide a deeper comparison of our findings, we included a meta-analysis, which indicated burnout among BHPs working on a military installation was equivalent with other professions. Providers working with military clients within the community reported lower burnout than other professionals. Findings suggest BHPs working on a military installation might be at greater risk of developing burnout. Burnout might be preventable by increasing job resources and decreasing job demands.

Documented suicides within the British Army during the Crimean War 1854-1856.

We have little understanding of the increased active duty military suicide rates found in the United States, and little understanding of what is historically normative for combatants. Therefore, we examined historical records on suicides among the British Army during the Crimean War for the years 1854-1856. There were 18 documented suicides in the British Army during this period. Calculating an accurate annual suicide rate per 100,000 is impossible because it is unclear how many of the 111,313 military personnel were in country for each of the 2 years of the war. However, the range is conservatively estimated between 8 and 16 per 100,000, with the likely answer somewhere near the middle. This suggests the possibility that increasing suicide rates among active duty military may be a modern U.S. phenomenon.

Use of evidence-based treatment for posttraumatic stress disorder in Army behavioral healthcare.

OBJECTIVE: To identify the extent to which evidence-based psychotherapy (EBP) and psychopharmacologic treatments for posttraumatic stress disorder (PTSD) are provided to U.S. service members in routine practice, and the degree to which they are consistent with evidence-based treatment guidelines. METHOD: We surveyed the majority of Army behavioral health providers (n = 2,310); surveys were obtained from 543 (26%). These clinicians reported clinical data on a total sample of 399 service member patients. Of these patients, 110 (28%) had a reported PTSD diagnosis. Data were weighted to account for sampling design and nonresponses. RESULTS: Army providers reported 86% of patients with PTSD received evidence-based psychotherapy (EBP) for PTSD. As formal training hours in EBPs increased, reported use of EBPs significantly increased. Although EBPs for PTSD were reported to be widely used, clinicians who deliver EBP frequently reported not adhering to all core procedures recommended in treatment manuals; less than half reported using all the manualized core EBP techniques. CONCLUSIONS: Further research is necessary to understand why clinicians modify EBP treatments, and what impact this has on treatment outcomes. More data regarding the implications for treatment effectiveness and the role of clinical context, patient preferences, and clinical decision-making in adapting EBPs could help inform training efforts and the ways that these treatments may be better adapted for the military.

Mental health of Canadian Forces members while on deployment to Afghanistan.

OBJECTIVE: The deployed environment poses special challenges to the delivery of effective in-theatre mental health care. Our study sought to identify the prevalence and impact of symptoms of mental health problems in Canadian Forces (CF) personnel serving in Task Force Afghanistan; and, to determine the use of, and perceived need for, mental health services in CF personnel while deployed. METHODS: Our study consisted of a cross-sectional survey of all 2779 CF personnel deployed to the province of Kandahar, Afghanistan, from February 15, 2010, to March 15, 2010. RESULTS: An important minority (8.5%) of the 1572 respondents (response rate = 57%) exceeded civilian criteria for symptoms of acute traumatic stress, major depression, or generalized anxiety. Prevalence of these 3 mental health problems increased with higher combat exposure and location in more isolated posts. A much larger fraction (31%) reported suffering a stress, emotional, alcohol, or family problem during the deployment. Only a minority of respondents with a mental health problem (26%) were currently interested in getting help. Almost one-half of respondents with a mental health problem perceived occupational dysfunction as a result, though two-thirds of respondents with occupational dysfunction were in the group without the 3 mental health problems assessed. CONCLUSIONS: The needs base for psychosocial support extends beyond personnel who meet conventional questionnaire criteria for traumatic stress, depression, or generalized anxiety. Future research is needed to understand what precise problems are driving this larger needs base and what precise supports (clinical or nonclinical) would be most appropriate.

Deaths by suicide while on active duty, active and reserve components, U.S. Armed Forces, 1998-2011.

Since 2010, suicide has been the second leading cause of death among U.S service members, exceeded only by war injury. Suicide mortality rates in the Army and Marine Corps have increased during the conflicts in Iraq and Afghanistan; however, most active duty service members who die by suicide have never deployed. During 1998-2011, 2,990 service members died by suicide while on active duty. Numbers and rates of suicide were highest among service members who were male, in the Army, in their 20s and of white race/ethnicity. Suicide death rates were 24 percent higher among divorced/separated than single, never-married service members. Firearms were the most frequently used method of suicide among both males and females. Numbers and rates of suicide among military members have increased sharply since 2005 and an increasing proportion of these suicides were by firearms. When adjusted for age, rates of suicide are somewhat lower among active military members than civilians. There are not well established and clearly effective interventions to prevent suicides--in general or specifically in a military population during wartime.

Mental disorders and mental health problems, active component, U.S. Armed Forces, 2000-2011.

Mental disorders account for significant morbidity, health care utilization, disability, and attrition from military service; the health care burden associated with mental disorders has increased over the last several years. During the years 2000 through 2011, 936,283 active component service members were diagnosed with at least one mental disorder. Annual counts and rates of incident diagnoses of mental disorders have increased by approximately 65 percent over the last twelve years; this overall increase is largely attributable to diagnoses of adjustment disorders, depressive and anxiety disorders, and post-traumatic stress disorder. Rates of incident mental disorder diagnoses were higher in females than males and in service members under 30 years of age. These findings reinforce previous reports that have documented a rise in demand for mental health services in the active component force and suggest that continued focus on detection and treatment for mental health issues is warranted.

Mental health diagnoses during the year prior to schizophrenia, U.S. Armed Forces, 2001-2010.

Identification of military members in the prodromal phase of schizophrenia may lead to earlier treatment and allow non-urgent transition away from military duties. This report documents the incidence of schizophrenia in the U.S. military and summarizes mental health diagnoses during the year prior to initial clinical diagnoses schizophrenia. During 2001-2010, 3,000 service members met the case definition of schizophrenia (incidence rate: 21 per 100,000 person-years). Rates declined with increasing age. Of those diagnosed with schizophrenia, 71% had at least one mental health-related medical encounter during the preceding 12 months; 51% received at least one antecedent diagnosis of paranoia. The findings may inform a model to predict the likelihood and timing of clinical manifestations of schizophrenia among U.S. military members.

Mental health advisory teams: a proactive examination of mental health during combat deployments.

Mental health advisory teams (MHATs) conduct comprehensive mental health surveillance of US service members in combat environments. Since 2003, six teams have deployed to Iraq and four have deployed to Afghanistan, and results have played a key role influencing behavioural health policy. The repeated deployments of the teams have provided opportunities for processes to be refined, and this refinement has led to a scientifically rigorous and replicable approach. In this article we focus on two themes. The first theme is how changes in sampling have influenced the nature of the inferences drawn from the survey-based surveillance data. The second theme is how the ability to utilize different forms of data has served to strengthen the programme. Focusing on these two themes provides a way to discuss key findings, recommendations and limitations while also interspersing practical observations intended to help inform the design of broad-scale, in-theatre mental health surveillance efforts. We believe that future surveillance efforts should build on the lessons of the MHATs and attempt to replicate the more rigorous sampling methods; nonetheless, we also strive to convey that large surveillance efforts are valuable even if they cannot be executed with random sampling.

Psychiatric diagnoses and punishment for misconduct: the effects of PTSD in combat-deployed Marines.

BACKGROUND: Research on Vietnam veterans suggests an association between psychological problems, including posttraumatic stress disorder (PTSD), and misconduct; however, this has rarely been studied in veterans of Operation Iraqi Freedom or Operation Enduring Freedom. The objective of this study was to investigate whether psychological problems were associated with three types of misconduct outcomes (demotions, drug-related discharges, and punitive discharges.) METHODS: A population-based study was conducted on all U.S. Marines who entered the military between October 1, 2001, and September 30, 2006, and deployed outside of the United States before the end of the study period, September 30, 2007. Demographic, psychiatric, deployment, and personnel information was collected from military records. Cox proportional hazards regression analysis was conducted to investigate associations between the independent variables and the three types of misconduct in war-deployed (n = 77,998) and non-war-deployed (n = 13,944) Marines. RESULTS: Marines in both the war-deployed and non-war-deployed cohorts with a non-PTSD psychiatric diagnosis had an elevated risk for all three misconduct outcomes (hazard ratios ranged from 3.93 to 5.65). PTSD was a significant predictor of drug-related discharges in both the war-deployed and non-war-deployed cohorts. In the war-deployed cohort only, a specific diagnosis of PTSD was associated with an increased risk for both demotions (hazard ratio, 8.60; 95% confidence interval, 6.95 to 10.64) and punitive discharges (HR, 11.06; 95% CI, 8.06 to 15.16). CONCLUSIONS: These results provide evidence of an association between PTSD and behavior problems in Marines deployed to war. Moreover, because misconduct can lead to disqualification for some Veterans Administration benefits, personnel with the most serious manifestations of PTSD may face additional barriers to care.

A suicide prevention advisory group at an academic medical center.

During a 15-month period, there were seven suicides among patients who were in active treatment or who had been seen recently by providers in the Department of Psychiatry of Tripler Army Medical Center, Honolulu, Hawaii. As a result, a Suicide Prevention Advisory Group (SPAG) was formed to identify possible causes and make recommendations aimed at improving the identification and treatment of suicidal patients. The group made 11 specific recommendations. No known suicides occurred during the 22 months after the implementation of the Suicide Prevention Advisory Group's recommendations.

U.S. military mental health care utilization and attrition prior to the wars in Iraq and Afghanistan.

OBJECTIVE: Health care utilization studies of mental disorders focus largely on the ICD-9 category 290-319, and do not generally include analysis of visits for mental health problems identified under V-code categories. Although active duty service members represent a large young adult employed population who use mental health services at similar rates as age-matched civilian populations, V-codes are used in a larger proportion of mental health visits in military mental health care settings than in civilian settings. However, the utilization of these diagnoses has not been systematically studied. The purpose of this study is to characterize outpatient behavioral health visits in military health care facilities prior to Operation Iraqi Freedom, including the use of diagnoses outside of the ICD-9 290-319 range, in order to evaluate the overall burden of mental health care. This study establishes baseline rates of mental health care utilization in military mental health clinics in 2000 and serves as a comparison for future studies of the mental health care burden of the current war. METHODS: All active duty service members who received care in military outpatient clinics in 2000 (n = 1.35 million) were included. Primary diagnoses were grouped according to mental health relevance in the following categories: mental disorders (ICD-9 290-319), mental health V-code diagnoses (used primarily by behavioral health providers that were indicative of a potential mental health problem), and all other diagnoses. Rates of service utilization within behavioral health clinics were compared with rates in other outpatient clinics for each of the diagnostic groups, reported as individuals or visits per 1,000 person-years. Cox proportional hazard regression was used to produce hazard ratios as measures of association between each of the diagnostic groups and attrition from military service. Time to attrition in months was the difference between the date of military separation and the date of first clinic visit in 2000. Data were obtained from the Defense Medical Surveillance System. RESULTS: The total number of individuals who utilized behavioral health services in 2000 was just over 115 per 1,000 person-years, almost 12% of the military population. Out of every 1,000 person-years, 57.5 individuals received care from behavioral health providers involving an ICD-9 290-319 mental disorder diagnosis, and an additional 26.7 per 1,000 person-years received care in behavioral health clinics only for V-code diagnoses. Attrition from service was correlated with both categories of mental health-related diagnoses. After 1 year, approximately 38% of individuals who received a mental disorder diagnosis left the military, compared with 23% of those who received mental health V-code diagnoses and 14% of those who received health care for any other reason (which included well visits for routine physicals). CONCLUSIONS: This study establishes baseline rates of pre-war behavioral healthcare utilization among military service members, and the relationship of mental health care use and attrition from service. The research indicates that in the military population the burden of mental illness in outpatient clinics is significantly greater when V-code diagnoses are included along with conventional mental disorder diagnostic codes.

Prevention of suicidal behaviour among army personnel: a qualitative study.

OBJECTIVES: To examine the context of suicidal behaviour among soldiers in the United Kingdom and identify factors that could reduce the risk of such behaviour. METHOD: A series of in-depth interviews with service providers involved in treating soldiers following deliberate self harm. Their responses were compared with those of a small sub-sample of soldiers who presented to Army medical services following self harm. RESULTS: We interviewed 21 service providers with a range of experience and professional backgrounds and 10 soldiers. Service providers told us that the rarity of suicide among soldiers together with lower levels of mental illness amongst those who end their lives made suicide prevention in the Army a difficult task. However they highlighted concerns about recruitment and retention of young soldiers, and stated that stigmatisation of mental illness in the Army sometimes prevented those with suicidal ideation seeking help. They also highlighted the role of alcohol use in precipitating self-harm. Soldiers who had self-harmed told us that they struggled to balance the demands of work and family life and described harming themselves impulsively often while intoxicated with alcohol. Soldiers look to sources of support outside the Army, and see commanding officers, rather than healthcare professionals, as helping resolve their problems. Neither service providers nor soldiers mentioned helplines and other 'independent' sources of confidential advice and support which are available to soldiers serving with the British Army. CONCLUSION: Our findings highlight problems associated with efforts to reduce suicide among soldiers but suggest that these should focus continuing to try to reduce stigmatisation of mental distress and specifically on the role of commanding officers. Greater efforts should also be made to publicise existing sources of help and reduce levels of alcohol misuse.

A review of one year of British Armed Forces mental health hospital admissions.

OBJECTIVES: The paper provides a review of one year of military Mental Health (MH) hospital admissions. This includes an exploration into demographic trends, differences in clinical opinion and how information gained is used to improve the service and ensure appropriate, cost effective care in the optimum environment. METHODS: The sample group is entitled military MH hospital admissions from 1 April 2005 to 31 March 2006. Data was collected on questionnaires with SPSS used for the management and analysis of the quantitative data, with the information exposed to descriptive and inferential statistical analysis. RESULTS: There were 344 admissions. The paper contains a detailed review of a number of variables. Depression was the most common diagnosis resulting in 112 (33%) hospital admissions and Post Traumatic Stress Disorder accounted for 23 (7%). There were statistically significant differences that may be attributable to gender with more women admitted with depression and more men with alcohol related disorders. The average length of stay was 21 days, with 48% of patients discharged within 3 weeks. 45% of all returns included significant events reporting that highlighted written evidence of good and poor practice. CONCLUSION: This study is part of an extensive monitoring programme of military MH hospital admissions. Depression is the most common MH problem leading to hospital admission. The results indicate that Service-personnel have access to a highly responsive service that provides brief assessment and treatment within a safe therapeutic environment. 45% of returns included significant event information that resulted in policy changes, leading to improved patient care and a better interface with the NHS. Bench-marking, both internally between military Departments of Community Mental Health and externally have improved visibility and self awareness leading to better GP induction programmes, PHC educational seminars and the establishment of MH web-pages. The Armed Forces need an effective MH service that is accessible, readily available, non-stigmatised and which positively advocates a duty of care. The results highlight the importance of further studies regarding depression to ensure that the Armed Forces are in a better position to maximise the use of MH resources.

Mental health treatment seeking by military members with posttraumatic stress disorder: findings on rates, characteristics, and predictors from a nationally representative Canadian military sample.

OBJECTIVE: The goal of this study was to identify rates, characteristics, and predictors of mental health treatment seeking by military members with posttraumatic stress disorder (PTSD). METHOD: Our sample was drawn from the 2002 Canadian Community Health Survey-Canadian Forces Supplement (CCHS-CF) dataset. The CCHS-CF is the first epidemiologic survey of PTSD and other mental health conditions in the Canadian military and includes 8441 nationally representative Canadian Forces (CF) members. Of those, 549 who met the criteria for lifetime PTSD were included in our analyses. To identify treatment rates and characteristics, we examined frequency of treatment contact by professional and facility type. To identify predictors of treatment seeking, we conducted a binary logistic regression with lifetime treatment seeking as the outcome variable. RESULTS: About two-thirds of those with PTSD consulted with a professional regarding mental health problems. The most frequently consulted professionals, during both the last year and lifetime, included social workers and counsellors, medical doctors and general practitioners, and psychiatrists. Consultations during the last year most often took place in a CF facility. Treatment seeking was predicted by cumulative lifetime trauma exposure, index traumatic event type, PTSD symptom interference, and comorbid major depressive disorder. Those with comorbid depression were 3.75 times more likely to have sought treatment than those without. CONCLUSIONS: Although a significant portion of military members with PTSD sought mental health treatment, 1 in 3 never did. Trauma-related and illness and (or) need factors predicted treatment seeking. Of all the predictors of treatment seeking, comorbid depression most increased the likelihood of seeking treatment.

A multisite study of Air Force outpatient behavioral health treatment-seeking patterns and career impact.

This study examined 1,068 cases of active duty Air Force service members seen in eight Air Force outpatient mental health clinics during a 1-year period. Age, gender, rank, marital status, special duty status, diagnostic category, treatment completion, and recommendations to the member's unit were examined across referral sources (i.e., self-referred, supervisor-referred, or commander-directed). Results showed significant differences across all variables, with self-referred members being more likely to be older, single, higher ranking, and without special duty status, as well as to have a less significant axis I diagnosis. Self-referred members were less likely to have confidentiality broken and to have career-affecting recommendations made. The implications of these findings, in terms of targeting interventions to increase self-initiated help-seeking behavior, and recommendations for future research are discussed.

Stress, mental health, and job performance among active duty military personnel: findings from the 2002 Department of Defense Health-Related Behaviors Survey.

This study examined the extent to which high levels of occupational and family stress were associated with mental health problems and productivity loss among active duty military personnel. We analyzed data from the 2002 Department of Defense Survey of Health-Related Behaviors among Military Personnel, which provided extensive population-based information on 12,756 active duty personnel in all branches of the military worldwide. Military personnel reported higher levels of stress at work than in their family life. The personnel reporting the highest levels of occupational stress were those 25 or younger, those who were married with spouses not present, and women. Personnel with high levels of stress had significantly higher rates of mental health problems and productivity loss than those with less stress. We recommend that prevention and intervention efforts geared toward personnel reporting the highest levels of stress be given priority for resources in this population.

Job stress, depression, work performance, and perceptions of supervisors in military personnel.

OBJECTIVE: Recent studies have identified high levels of job stress in military personnel. This study examined the relationship among job stress, depression, work performance, types of stressors, and perceptions about supervisors in military personnel. METHODS: Eight hundred nine military personnel answered a 43-item survey on work stress, physical and emotional health, work performance, perceptions about leadership, job stressors, and demographics. RESULTS: More than one- quarter (27.4%) of this military population reported suffering from significant job stress. Both the report of work stress and depression were significantly related to impaired work performance, more days of missed work, poorer physical health, and negative perceptions about the abilities of supervisors and commanders. Depression and job stress were significantly and positively related to each other. CONCLUSIONS: These results support accumulating data indicating that work stress is a significant occupational health hazard in the routine military work environment. Targeting and eliminating sources of job stress should be a priority for the U.S. military to preserve and protect the mental health of military personnel.

First psychiatric hospitalizations in the US military: the National Collaborative Study of Early Psychosis and Suicide (NCSEPS).

BACKGROUND: Military samples provide an excellent context to systematically ascertain hospitalization for severe psychiatric disorders. The National Collaborative Study of Early Psychosis and Suicide (NCSEPS), a collaborative study of psychiatric disorders in the US Armed Forces, estimated rates of first hospitalization in the military for three psychiatric disorders: bipolar disorder (BD), major depressive disorder (MDD) and schizophrenia. METHOD: First hospitalizations for BD, MDD and schizophrenia were ascertained from military records for active duty personnel between 1992 and 1996. Rates were estimated as dynamic incidence (using all military personnel on active duty at the midpoint of each year as the denominator) and cohort incidence (using all military personnel aged 18-25 entering active duty between 1992 and 1996 to estimate person-years at risk). RESULTS: For all three disorders, 8723 hospitalizations were observed in 8,120,136 person-years for a rate of 10.7/10,000 [95% confidence interval (CI) 10.5-11.0]. The rate for BD was 2.0 (95% CI 1.9-2.1), for MDD, 7.2 (95% CI 7.0-7.3), and for schizophrenia, 1.6 (95% CI 1.5-1.7). Rates for BD and MDD were greater in females than in males [for BD, rate ratio (RR) 2.0, 95% CI 1.7-2.2; for MDD, RR 2.9, 95% CI 2.7-3.1], but no sex difference was found for schizophrenia. Blacks had lower rates than whites of BD (RR 0.8, 95% CI 0.7-0.9) and MDD (RR 0.8, 95% CI 0.8-0.9), but a higher rate of schizophrenia (RR 1.5, 95% CI 1.3-1.7). CONCLUSIONS: This study underscores the human and financial burden that psychiatric disorders place on the US Armed Forces.
