Importance of anonymity to encourage honest reporting in mental health screening after combat deployment.

CONTEXT: US soldiers are required to undergo screening for depression, posttraumatic stress disorder (PTSD), and other mental health problems on return from service in Iraq or Afghanistan as part of routine postdeployment health assessments. OBJECTIVE: To assess the influence of the anonymity of screening processes on willingness of soldiers to report mental health problems after combat deployment. DESIGN: Anonymous and nonanonymous surveys. SETTING: US military. PATIENTS: US infantry soldiers' reporting of mental health problems on the routine Post-Deployment Health Assessment was compared with their reporting on an anonymous survey administered simultaneously. MAIN OUTCOME MEASURES: The Primary Care PTSD Screen, the Patient Health Questionnaire-2 (modified), the suicidal ideation question from the Patient Health Questionnaire-9, and several other questions related to mental health were used on both surveys. Soldiers were also asked on the anonymous survey about perceptions of stigma and willingness to report honestly. RESULTS: Of 3502 US Army soldiers from one infantry brigade combat team undergoing the routine Post-Deployment Health Assessment in 2008, a total of 2500 were invited to complete the anonymous survey, and 1712 of these participated (response rate, 68.5%). Reporting of depression, PTSD, suicidal ideation, and interest in receiving care were 2-fold to 4-fold higher on the anonymous survey compared with the routine Post-Deployment Health Assessment. Overall, 20.3% of soldiers who screened positive for depression or PTSD reported that they were uncomfortable reporting their answers honestly on the routine postdeployment screening. CONCLUSIONS: Current postdeployment mental health screening tools are dependent on soldiers honestly reporting their symptoms. This study indicates that the Post-Deployment Health Assessment screening process misses most soldiers with significant mental health problems. Further efforts are required to reduce the stigma of reporting and improve willingness to receive care for mental health problems.

Effectiveness of battlefield-ethics training during combat deployment: a programme assessment.

BACKGROUND: Breakdowns in the ethical conduct of soldiers towards non-combatants on the battlefield are of grave concern in war. Evidence-based training approaches to prevent unethical conduct are scarce. We assessed the effectiveness of battlefield-ethics training and factors associated with unethical battlefield conduct. METHODS: The training package, based on movie vignettes and leader-led discussions, was administered 7 to 8 months into a 15-month high-intensity combat deployment in Iraq, between Dec 11, 2007, and Jan 30, 2008. Soldiers from an infantry brigade combat team (total population about 3500) were randomly selected, on the basis of company and the last four digits of each soldier's social security number, and invited to complete an anonymous survey 3 months after completion of the training. Reports of unethical behaviour and attitudes in this sample were compared with a randomly selected pre-training sample from the same brigade. The response patterns for ethical behaviour and reporting of ethical violations were analysed with chi-square analyses. We developed two logistic regression models using self-reported unethical behaviours as dependent variables. Factors associated with unethical conduct, including combat experiences and post-traumatic stress disorder (PTSD), were assessed with validated scales. FINDINGS: Of 500 randomly selected soldiers 421 agreed to participate in the anonymous post-training survey. A total of 397 soldiers of the same brigade completed the pre-training survey. Training was associated with significantly lower rates of unethical conduct of soldiers and greater willingness to report and address misconduct than in those before training. For example, reports of unnecessary damage or destruction of private property decreased from 13·6% (54 of 397; 95% CI 10·2-17·0) before training to 5·0% (21 of 421; 2·9-7·1) after training (percent difference -63·2%; p<0·0001), and willingness to report a unit member for mistreatment of a non-combatant increased from 36·0% (143 of 397; 31·3-40·7) to 58·9% (248 of 421; 54·2-63·6; percent difference 63·6; p<0·0001). Nearly all participants (410 [97%]) reported that training made it clear how to respond towards non-combatants. Combat frequency and intensity was the strongest predictor of unethical behaviour; PTSD was not a significant predictor of unethical behaviour after controlling for combat experiences. INTERPRETATION: Leader-led battlefield ethics training positively influenced soldiers' understanding of how to interact with and treat non-combatants, and reduced reports of ethical misconduct. Unethical battlefield conduct was associated with high-intensity combat but not with PTSD. FUNDING: None.

Suicide prevention in a deployed military unit.

OBJECTIVE: Military suicide and parasuicidal behaviors have been increasing over the last several years, with rates highest in the deployed environment. This article presents a deployment cycle-specific suicide prevention plan utilized during one U.S. Army division's 15-month deployment to Iraq. METHODS: Education, identification, and intervention programs were implemented at each phase of the deployment cycle based on the specific unit activities and predicted stressors. RESULTS: During the deployment, there was an annual suicide rate of 16/100,000 within the trial cohort, compared to a theater rate of 24/100,000. Peaks in suicidal ideation and behaviors occurred during months two, six, and twelve of deployment. CONCLUSIONS: A deployment cycle prevention program may decrease rates of suicide in the combat environment. This program may serve as a model for other suicide prevention programs.

Acute stress disorder, depression, and tobacco use in disaster workers following 9/11.

Early posttraumatic psychiatric disorders have not been well studied in disaster workers. This study examined the rates of probable acute stress disorder (ASD), probable depression, increased tobacco use, and their associated risk factors in 9/11 World Trade Center disaster workers. Surveys were obtained from 90 disaster workers (e.g., medical personnel, police, firefighters, search and rescue) 2-3 weeks after 9/11. Nearly 15% of disaster workers had probable ASD and 26% had probable depression. Probable ASD and depression were highly related to functional impairment. The risk for ASD was increased for those with 9/11-specific disaster exposures, more pre-9/11 trauma exposures, and the peritraumatic dissociative symptom of altered sense of time. Disaster workers who were younger, non-White, or who had increasing numbers of peritraumatic dissociative symptoms were more likely to have probable depression. More than half of tobacco users increased their tobacco use after 9/11. Additionally, all tobacco users with probable ASD and almost all tobacco users with probable depression increased tobacco use. Rapid mobilization of resources for early screening and intervention and health promotion campaigns aimed at improving adverse health-related behaviors may be helpful for this high-risk group.

Ethical considerations in military psychiatry.

Military psychiatrists are faced with multiple, difficult questions that shape the context for ethical patient care. These questions are difficult to answer and future efforts, including policy and evidence-based treatment practices, should aim at reducing the ambiguity faced by military psychiatrists. New research should focus on issues as diverse as optimal approaches to informed consent, evidence-derived approaches to protecting confidentiality, outcomes of care for individuals in widely varying military roles, and medication use in the field. Training for mental health care providers who deal with military patients should be provided not only in military graduate medical education but also in job-specific courses and in ethics. This should include specific training for personnel who will be dealing with specific populations, such as the US Army's current "Dealing with Detainee course" and the Army Medical Department's "Combat Operational Stress Course" for deploying military psychiatrists and psychologists.

Soldier attitudes toward mental health screening and seeking care upon return from combat.

OBJECTIVE: This study examined soldier attitudes about postdeployment mental health screening, treatment, barriers to care, strategies for overcoming barriers, and settings, personnel and timing for conducting postdeployment mental health screening. METHODS: Deploying soldiers participated in a voluntary anonymous survey. RESULTS: Of 3,294 soldiers, 2,678 (81.3%) responded to the survey. When the three most endorsed perceived barriers to mental health care (negative perception by unit members, negative perception by leaders, and being viewed as weak) were examined, approximately 15% fewer soldiers endorsed the perceptions, compared with a previous study conducted at the beginning of the war. Receipt of training focused on managing psychological problems associated with increased agreement to seek treatment. Participants endorsed surveys, interviews, and unit providers as preferred instruments and providers for postdeployment screening. Soldiers endorsed encouragement from family members and friends as the preferred approach to reducing barriers to mental health care. CONCLUSION: Extensive educational programs seemed to have reduced the stigma related to receiving mental health care. Programs that focus on friend and family member encouragement of soldiers to seek mental health assistance should continue. Postdeployment screening should be conducted under conditions in which soldiers are most likely to report problems honestly.

Military family physician attitudes toward treating obesity.

OBJECTIVE: The goal was to examine current knowledge, attitudes, and treatment practices of family practitioners regarding obesity. METHODS: A cross-sectional, anonymous, self-report survey of active members of the Uniformed Services Chapter of the American Academy of Family Physicians was performed. Measures included demographic information, attitudes toward obese patients, knowledge of associated health risks, and treatment recommendations, rated on a 5-point Likert scale. Results were compared with previous similar studies, and associations between demographic variables, physician body mass index, and attitudes and behaviors were examined by using multivariate regression analysis. RESULTS: Of the 1,186 members invited to participate, 477 (40.2%) responded. Compared with previous studies, there was increased awareness of obesity-associated health risks and physicians' sense of obligation to counsel patients. There were minimal changes in physician comfort and gratification with obesity counseling. Stereotypical attitudes of physicians toward obese patients were increased. Treatment recommendations were increased in all fields, including exercise, diet/nutrition counseling, and behavioral modification, but the most notable increases were seen in the use of prescription medications, diet center programs, and surgical referrals. Age, physician gender, physician weight status, practice location, and current training status were each associated with some aspect of physician attitudes and treatment practices. CONCLUSION: Physicians are better able to identify obesity and its associated health risks, but some negative stereotypical attitudes persist. These attitudes affect current treatment practices. Increased awareness, training, and study are required to combat the continuing increase in obesity rates.

Models of PTSD and traumatic stress: the importance of research "from bedside to bench to bedside".

The epidemiology and psychology of PTSD noted above is not often considered in neurobiological models of PTSD. Neurobiological models tend to focus on symptoms. This is an important perspective but it does not capture the brains total response to traumatic events. Similarly, neurobiologists have rarely used the extensive knowledge of animal behavioral responses to stress as a means to define the human stress phenomenology, looking for the human equivalent (rather than the other way around). The development of animal models for PTSD and other traumatic stress-related brain changes is an important part of advancing our neurobiological understanding of the disease process as well as recovery, resilience, and possible therapeutic targets. Animal models should address symptoms but also other aspects of PTSD that are seen in clinical care including the waxing and waning of symptoms, Understanding "forgetting", toxic exposure, failure to recover and how the neural systems fail rather than function are important perspectives on developing animal models. The cognitive process of identification is another important animal model to develop. Using these perspectives recent work has shown new avenues for understanding the trauma response in animal models and human brain tissue of individuals with PTSD. The 5-HT2A receptor and p11 protein and associated regulators are avenues of new investigation that warrant study and consideration in models of PTSD.

Postdeployment Health Reassessment: a sustainable method for brigade combat teams.

OBJECTIVE: The Postdeployment Health Reassessment (PDHRA) was mandated in 2006 and the 3rd Infantry Division was the first unit to perform a large-scale implementation. This article outlines a reproducible model for conducting PDHRA using only existing resources. METHODS: The PDHRA (DD 2900) screening and referral processes are reviewed and data on positive screens are reported. RESULTS: Of the 12,817 soldiers who participated in the mass screening, 1,460 (11.4%) were referred for behavioral health, 815 (6.4%) for primary care, 71 (0.01%) for specialty services, and 9 (0.001%) for emergency services. Consult requests were higher in maneuver brigades than in support units (12.1% versus 8.6% for behavioral health and 6.9% versus 4.4% for primary care referrals). All (1,460, 100%) of the behavioral health consults were completed on-site and the unit incurred no additional financial cost in conducting this process. CONCLUSIONS: This method for performing a large-scale implementation of the PDHRA provides a flexible, efficient, and cost-effective process that could be implemented at the brigade combat team level without difficulty and in most locations without significant impact on other medical demands.

Division mental health in the new brigade combat team structure: part I. Predeployment and deployment.

OBJECTIVE: Recent Army transformation has led to significant changes in roles and demands for division mental health (DMH) staff members. This article focuses on predeployment and deployment. METHODS: Surveillance of Combat and Operational Stress Reactions data, review of DMH implementation plans, and observations by staff members, providers, and soldiers were reviewed. RESULTS: During the course of the deployment, the Task Force Baghdad DMH unit had >22,000 soldier encounters with 5,542 clinical encounters. The duration of the deployment and increased levels of threat later in the deployment resulted in increased stress problems but not a substantial or sustained increase in mental health casualties. CONCLUSIONS: Predeployment education and communication probably eliminated some problems during deployment, and communication among mental health and command units during deployment resolved most problems encountered.

Division mental health in the new brigade combat team structure: part II. Redeployment and postdeployment.

OBJECTIVE: Recent Army transformation has led to significant changes in roles and demands for division mental health staff members. This article focuses on redeployment and postdeployment. METHODS: The postdeployment health assessment behavioral health screening and referral process and redeployment plan are reviewed, and data on postdeployment rates of negative events are reported. RESULTS: All soldiers and many of their families participated in an aggressive education program. Of the 19,500 soldiers screened, 2,170 (11.1%) were referred for behavioral health consultation; of those referred, 219 (10.1%) were found to be at moderate or high risk for mental health issues (1.1% of total screened). Of the moderate/highrisk soldiers, 146 (71.9%) accepted follow-up mental health treatment upon return to home station. Fewer cases of driving under the influence, positive drug screens, suicidal gestures/ attempts, crimes, and acts of domestic violence were seen, in comparison with rates seen after an earlier deployment of this unit to Iraq. CONCLUSIONS: A formalized approach with command support and coordination can have a positive impact on successful referral and treatment and reduce negative postdeployment events.

The evolving role of the division psychiatrist.

With the recent restructuring of Army infantry divisions in the new brigade combat team model, division psychiatrists are facing new and unique demands. This article outlines the varying perspectives of the position and the duties and responsibilities of a division psychiatrist. It provides guidance on how to negotiate the myriad of challenges unique to the position. Discussion includes planning and supervision, providing command consultation, educational efforts, fulfilling the roles of an officer and leader, and future directions for the position.

Depression in entry-level military personnel.

OBJECTIVE: The goal was to determine the prevalence of, and risk factors for, depression in an entry-level U.S. Army population. METHOD: A cross-sectional survey of U.S. Army soldiers in advanced individual training was performed by using an anonymous self-report survey including demographic data, history (including abuse and psychiatric treatment), and the Patient Health Questionnaire-9. RESULTS: Soldiers in advanced individual training (n = 1,184) were approached, and 1,090 (91.2%; 955 male soldiers and 135 female soldiers) voluntarily chose to participate. Eleven percent reported a psychiatric history, 26% reported a history of abuse, and 15.9% endorsed moderate or more severe current depressive symptoms (male, 15.0%; female, 22.2%). A history of psychiatric treatment (odds ratio, 2.08; 95% confidence interval, 1.21-3.59; p = 0.009) and a history of verbal abuse (odds ratio, 4.11; 95% confidence interval, 2.45-6.90; p = 0.000) placed soldiers at higher risk for depression. CONCLUSIONS: Our study shows a higher than expected rate of depression in entry-level training soldiers and identifies some risk factors for depression. This indicates an important need for further study, effective screening, preventive counseling, and early intervention.

Post-traumatic stress disorder and depression in health care providers returning from deployment to Iraq and Afghanistan.

OBJECTIVE: This study examines risk factors for post-traumatic stress disorder (PTSD), depression, and mental health care use among health care workers deployed to combat settings. METHODS: Anonymous surveys were administered to previously deployed workers at a military hospital. PTSD and depression were assessed by using the PTSD Checklist and the Patient Health Questionnaire depression scale, respectively. Deployment exposures and perceived threats during deployment were also assessed. RESULTS: There were 102 respondents (36% response rate). Nine percent (n=9) met the criteria for PTSD and 5% (n=5) met the criteria for depression. Direct and perceived threats of personal harm were risk factors for PTSD; exposure to wounded or dead patients did not increase risk. Those who met the criteria for PTSD were more likely to seek mental health care after but not before their deployment. CONCLUSIONS: For health care workers returning from a warfare environment, threat of personal harm may be the most predictive factor in determining those with subsequent PTSD.

Disordered eating in entry-level military personnel.

OBJECTIVE: The goal was to determine the prevalence of and risk factors for disordered eating in an entry-level U.S. Army population. METHODS: A cross-sectional survey of advanced individual training U.S. Army soldiers at Aberdeen Proving Ground, Maryland, was performed with an anonymous self-report survey containing demographic factors, history (including abuse and psychiatric treatment), and Eating Attitudes Test-26. RESULTS: Of 1,184 advanced individual training soldiers approached, 1090 participated. The response rate was 91.2% (955 men and 135 women). Forty percent were overweight (body mass index of > or =25), 11% reported a psychiatric history, 26% reported a history of abuse, and 9.8% endorsed disordered eating (male, 7.0%; female, 29.6%), as defined by Eating Attitudes Test-26. Factors that placed soldiers at higher risk for disordered eating were female gender (odds ratio, 5.63; 95% confidence interval, 3.32-9.57; p < 0.00005), overweight (odds ratio, 3.06; 95% confidence interval, 1.92-4.89; p < 0.00005), previous psychiatric treatment (odds ratio, 1.87; 95% confidence interval, 1.04-3.36; p = 0.035), and history of verbal abuse (odds ratio, 2.02; 95% confidence interval, 1.16-3.51; p = 0.014). CONCLUSIONS: Our study shows a higher than expected rate of disordered eating in advanced individual training soldiers with identifiable risk factors. This indicates an important need for further study, effective screening, preventive counseling, and early intervention for treatment.

Posttraumatic stress disorder and depression in battle-injured soldiers.

OBJECTIVE: This study examined rates, predictors, and course of probable posttraumatic stress disorder (PTSD) and depression among seriously injured soldiers during and following hospitalization. METHOD: The patients were 613 U.S. soldiers hospitalized following serious combat injury. Standardized screening instruments were administered 1, 4, and 7 months following injury; 243 soldiers completed all three assessments. Cross-sectional and longitudinal analyses of risk factors were performed. PTSD was assessed with the PTSD Checklist; depression was assessed with the Patient Health Questionnaire. Combat exposure, deployment length, and severity of physical problems were also assessed. RESULTS: At 1 month, 4.2% of the soldiers had probable PTSD and 4.4% had depression; at 4 months, 12.2% had PTSD and 8.9% had depression; at 7 months, 12.0% had PTSD and 9.3% had depression. In the longitudinal cohort, 78.8% of those positive for PTSD or depression at 7 months screened negative for both conditions at 1 month. High levels of physical problems at 1 month were significantly predictive of PTSD (odds ratio=9.1) and depression at 7 months (odds ratio=5.7) when the analysis controlled for demographic variables, combat exposure, and duration of deployment. Physical problem severity at 1 month was also associated with PTSD and depression severity at 7 months after control for 1-month PTSD and depression severity, demographic variables, combat exposure, and deployment length. CONCLUSIONS: Early severity of physical problems was strongly associated with later PTSD or depression. The majority of soldiers with PTSD or depression at 7 months did not meet criteria for either condition at 1 month.

Follow-up of Pentagon employees two years after the terrorist attack of September 11, 2001.

OBJECTIVE: This study examined probable posttraumatic stress disorder (PTSD) and probable depression, degree of psychological distress, and rates of mental health treatment in a sample of Pentagon staff two years after the terrorist attack of September 11, 2001. METHODS: Anonymous surveys were administered to staff at one Pentagon work center. Respondents were asked about exposure to the attack; injuries; exposure to dead bodies or families of the deceased; psychological distress; and use of mental health services. Probable PTSD and depression were assessed with the PCL-17 and the PHQ-9. RESULTS: A total of 267 responses were received. Fourteen percent of the sample had probable PTSD, and 7 percent had probable depression. Staff who were at the Pentagon on the day of the attack were more likely to have probable PTSD and probable depression. Exposure through watching television was not associated with a higher frequency of probable PTSD, probable depression, or distress. Injury during the attack was associated with a higher frequency of probable PTSD, probable depression, and distress. Respondents who were exposed to dead bodies or who acted as lay counselors to families of the deceased were more likely to have probable PTSD and depression and to report chronic distress. Of those with probable PTSD, 70 percent made at least one mental health visit during the next two years. Of those with probable depression, 74 percent reported at least one mental health visit. CONCLUSIONS: Direct exposure to the September 11 terrorist attack on the Pentagon, injury during the attack, and exposure to dead bodies or acting as a lay counselor to families of persons who were killed during the attack were all associated with higher frequencies of probable psychiatric illness and higher levels of psychological distress two years after the attack. Among survivors who had probable psychiatric illness, more than two-thirds received mental health treatment after the attack.

Psychiatric symptoms and cognitive appraisal following the near sinking of a research submarine.

OBJECTIVE: This study assessed the stress reactions of a submarine crew forced to abandon their vessel in high seas after flooding and fire damaged their ship. METHODS: The remaining crew members (n = 22) were surveyed 7 months after the incident regarding exposures, initial emotional responses, peritraumatic dissociation, subsequent life events, current safety appraisal, and current symptoms of posttraumatic stress disorder (PTSD) and depression. RESULTS: At 7 months, 9.1% met criteria for PTSD and none met criteria for depression. Higher levels of depressive symptoms were associated with previous traumatic exposures, subsequent life events, and higher levels of PTSD symptoms; higher levels of PTSD symptoms were associated with greater peritraumatic dissociation and initial emotional response. CONCLUSION: Acute exposures of highly trained professionals to potentially fatal events may not result in high levels of posttraumatic symptoms. Previous and subsequent life events may play a more significant role in the level of postdisaster symptoms.
