The changing patterns of psychiatric problems in Vietnam

I contend that military psychiatrists have been premature in suggesting that the Vietnam conflict has produced fewer psychiatric casualties than previous wars. While the number of men hospitalized and evacuated because of psychiatric problems has decreased, there has been a concurrent increase in disciplinary problems, drug abuse, and in the number of men diagnosed as character disorders. For some of our troops, duty in Vietnam has produced significant feelings of depression and guilt and has led to a rejection of any identification with the military. Other soldiers have turned to drug abuse as an escape from their distress. Men with character disorders sometimes act out their conflicts in antisocial behavior. The varying patterns of group formation in combat and support units determine whether this behavior will be directed towards Vietnamese or U.S. personnel. Antisocial behavior and drug abuse are symptomatic of emotional distress and have replaced combat fatigue as the predominant psychiatric syndromes among United States troops in Vietnam.     

Self-reported mental health difficulties and subsequent risk for schizophrenia in females: a 5-year follow-up cohort study

BACKGROUND: Patients with schizophrenia often report a history of premorbid mild to severe psychological distress. We investigated the association between self-reported mental health difficulties and later psychiatric hospitalization for schizophrenia. METHODS: 13,357 females aged 17, mandatory assessed by the Israeli Draft Board were followed up over 5 years for psychiatric hospitalization by means of the Israeli National Psychiatric Hospitalization Case Registry. Seventeen females, judged healthy at Draft Board assessment, were hospitalized for schizophrenia or schizoaffective disorder over the follow-up period. RESULTS: There was a significant monotonic association between increasing self-reported mental health difficulties (psychological distress and increasing need for psychological counseling) and prevalence of schizophrenia [odds ratios over four levels: 1.56; 95% CI:1.04 to 2.34; chi2 (1) = 4.62, p = 0.03], after controlling for low IQ, immigration, SES, and presence of psychiatric disorders at age 17. Increasing severity of self-reported mental health difficulties was related to earlier age of first hospitalization [r = -0.48, p = 0.05]. CONCLUSIONS: Increased undifferentiated self-reported mental health difficulties are associated with increased risk of later hospitalization for schizophrenia prior to age 23 in females. This may reflect the prodromal phase of the illness.     

Combat-related PTSD and psychosocial adjustment problems among substance abusing veterans

The purpose of this study were the following: a) to determine the prevalence of combat-related posttraumatic stress disorder (PTSD) symptoms among veterans seeking assistance at a Veterans Administration medical center substance abuse treatment facility, b) to examine the relative contribution of Vietnam war zone variables to PTSD symptom development, and c) to study psychosocial adjustment problems associated with Vietnam combat exposure and with PTSD symptoms among help-seeking substance abusing men. Of 489 male veterans presenting for treatment, 10.7% had significant Vietnam combat-related PTSD symptoms as measured by the Mississippi Scale for Combat-Related PTSD. Clinically significant PTSD symptoms occurred among 46% of the subsample of combat-exposed Vietnam veterans with substance abuse problems. Degree of combat exposure was the most important military stressor that distinguished Vietnam veterans with PTSD from those without PTSD, but the groups also differed on age of war zone duty, duration of war zone duty, and whether they were wounded. Veterans who served in Vietnam did not differ from veterans who had no war zone duty on various parameters of psychosocial adjustment. However, the subgroup of Vietnam veterans with PTSD symptoms reported significantly greater psychosocial adjustment problems than their counterparts who did not have PTSD. The deleterious effects associated with combat-related PTSD appeared to be confined to adjunctive psychiatric difficulties and unemployment and did not increase risk of arrests for antisocial conduct beyond that found for veterans without PTSD. Methodological and clinical implications of these findings are discussed.     

Incidence of hospitalization for postpartum psychotic and bipolar episodes in women with and without prior prepregnancy or prenatal psychiatric hospitalizations

CONTEXT: Postpartum psychosis occurs in 1 to 2 cases per 1000 live births. Most studies have not distinguished postpartum psychosis from bipolar disorder or the proportion of the incidence attributable to prepregnancy psychiatric morbidity. OBJECTIVE: To determine the incidence of postpartum psychosis and bipolar disorder attributable to previous psychiatric hospitalization. DESIGN: Population-based study using linked registry data to determine postpartum onset of psychotic and bipolar episodes within 90 days after the first birth, by women with and without prepregnancy or prenatal psychiatric hospitalization. We assessed the type, number, and recency of previous hospitalizations on the incidence of hospitalization for postpartum psychotic and bipolar episodes. SETTING: Nationwide Swedish Hospital Discharge and Medical Birth registers. PATIENTS: Swedish women delivering a first live infant between January 1, 1987, and December 31, 2001. MAIN OUTCOME MEASURES: Postpartum hospitalization for psychosis or bipolar disorder. RESULTS: The cumulative incidences for postpartum psychotic and bipolar episodes (adjusted for age at first birth) were 0.07% and 0.03%, respectively. The incidence of psychiatric hospitalizations for postpartum psychotic or bipolar episodes among women without previous psychiatric hospitalizations was 0.04% and 0.01% of first births, respectively; for women with any psychiatric hospitalization before delivery, the incidence was 9.24% and 4.48%, respectively. For postpartum psychotic and bipolar episodes, the risk increased significantly with the recency of prepregnancy hospitalizations, number of previous hospitalizations, and length of most recent hospitalization. More than 40% of women hospitalized during the prenatal period for a bipolar or a psychotic condition were hospitalized again during the postpartum period. Approximately 90% of all postpartum psychotic and bipolar episodes occurred within the first 4 weeks after delivery. CONCLUSIONS: Almost 10% of women hospitalized for psychiatric morbidity before delivery develop postpartum psychosis after their first birth. This underscores the need for obstetricians to assess history of psychiatric symptoms and, with pediatric and psychiatric colleagues, to optimize the treatment of mothers with psychiatric diagnoses through childbirth.     

Parental Iraq/Afghanistan deployment and child psychiatric hospitalization in the US military

Objective

Members of the US armed forces have been heavily deployed in support of wars in Afghanistan and Iraq. This study examined the affect of a parent's deployment to war on the rate of psychiatric hospitalization among their children.

Methods

This was a retrospective cohort study. Records of children of active duty personnel during fiscal years 2007 through 2009 were linked with their parent's deployment records. Psychiatric hospitalizations were identified using International Classification of Diseases, Ninth Revision codes on admission. Odds ratios (OR) of hospitalization were determined using both univariate and multivariate logistic regression. Lengths of hospital stay were also compared by linear regression using Duan's smearing estimate method.

Results

A total of 377,565 children aged 9–17 years were included along with data on both their active duty and civilian parent. Mean child age was 12.53 years (S.D.: 2.5 years); 51% were male. Mean age of active duty parent was 37.8 years (S.D.: 5.2 years); 93% were male, 90% were married and 62% were white. In the study, 2533 children were hospitalized for a mental or behavioral health disorder in fiscal year 2009 with a median length of stay of 8 days. After adjusting for demographic data and past psychiatric history of the child, active duty parent and civilian parent, the OR of hospitalization for children with a recently deployed parent was 1.10 (95% confidence interval: 1.01–1.19). The OR of hospitalization increased with increasing length of deployment with a positive test of trend. There was no statistically significant difference in distribution of admission diagnoses or length of hospital stay based on deployment by the active duty parent.

Conclusions

Psychiatric hospitalization increased by 10% among children aged 9–17 years when a military parent was recently deployed. The odds of hospitalization increased with increasing length of a parent's deployment.     

Multidimensional assessment of anger in Vietnam veterans with posttraumatic stress disorder.

This study examined the effects of combat exposure and posttraumatic stress disorder (PTSD) on dimensions of anger in Vietnam veterans. Vietnam combat veterans were compared with Vietnam era veterans without war zone duty on the Multidimensional Anger Inventory (MAI). Combat veterans were not significantly more angry than their veteran peers who did not serve in Southeast Asia. Additionally, various parameters of war zone duty were not highly associated with anger scores. However, combat veterans with PTSD scored significantly higher than veterans without PTSD on measures of anger arousal, range of anger-eliciting situations, hostile attitudinal outlook, and tendency to hold anger in. These results suggest that PTSD, rather than war zone duty, is associated with various dimensions of angry affect.     

Gender differences in the expression of PTSD symptoms among active duty military personnel

This study examined gender differences in posttraumatic stress disorder (PTSD) symptoms and symptom factors in the total U.S. active duty force. Data were drawn from the 2008 Department of Defense Survey of Health Related Behaviors among Active Duty Military Personnel including 17,939 men and 6751 women from all services. The results indicated that women expressed more distress than men across almost all the symptoms on the PTSD Checklist except for hypervigilance. Women also scored significantly higher on all four factors examined: Re-experiencing, Avoidance, Emotionally Numb, Hyperarousal. More women than men were distressed by combat experiences that involved some type of violence, such as being wounded, witnessing or engaging in acts of cruelty, engaging in hand-to-hand combat, and, to a lesser extent, handling dead bodies. Men who had been sexually abused had a greater number of symptoms and were consistently more distressed than women on individual symptoms and symptom factors.     

Patterns and correlates of psychiatric hospitalization in a nationwide sample

Summary A nationwide random sample of psychiatric patients (n=832) admitted for hospitalization in Israel in 1980 was followed up until the end of 1984. A multivariate analysis was performed, where the dependent variables were: the cumulative length of all hospitalizations, the mean duration of hospitalization and the mean length of stay out of hospital. The independent variables were: age, sex, marital status, ethnic origin, diagnosis, and various indices of previous hospitalizations. For patients whose hospitalization in 1980 (index hospitalization) was the first in their life, older age and male gender predicted a low probability of readmission, and the diagnosis of schizophrenia a long cumulative stay. For patients whose index hospitalization was not the first in their life, the main variables predictive of long cumulative stay were: old age, being single, long duration and high frequency of previous hospitalizations. Patients tended to maintain the same relative length of inpatients stay and the same frequency of readmission from the beginning of their hospitalization history.     

Psychological and marital distress in spouses of Vietnam veterans: Importance of spouses’ perceptions

Spouses of combat veterans with PTSD have greater psychological and marital distress than spouses of veterans without PTSD; however, few studies have examined how variables related to the spouses (e.g., cognitions) may play a role in their own distress. The current study examined spouses’ perceptions of combat veterans’ PTSD symptom severity in 465 spouses of veterans from the National Vietnam Veterans Readjustment Study. Spouses’ perceptions of veterans’ symptom severity were positively associated with spouses’ psychological and marital distress; furthermore, spouses’ perceptions fully mediated the effects of veterans’ self-reported PTSD severity on spouses’ distress. Additionally, for spouses who provided complete data with regard to their perceptions of veterans’ PTSD, distress was highest when they perceived high levels of symptoms but veterans reported low levels. These results highlight the importance of interpersonal perceptions in intimate relationships and provide preliminary groundwork for future research on cognitions in spouses of combat veterans with PTSD.     

Combat experience and postservice psychosocial status as predictors of suicide in Vietnam veterans

The authors examined potential risk factors for suicide among 38 Vietnam veterans using 46 Vietnam veterans who died from motor vehicle accidents as a comparison group. The veterans were selected from Los Angeles County Medical Examiner's file (1977-1982). Data for these veterans were obtained from military service records, the coroner's reports, and the psychological autopsy conducted with the decedents' family members. No military service factor was associated with suicide. The characteristics of Vietnam veteran suicide cases were not substantially different from non-Vietnam veteran suicide cases with respect to known demographic risk factors. The psychological profile of Vietnam veteran suicide cases are also similar to non-Vietnam veteran suicide cases in most instances. Symptoms related to posttraumatic stress disorder were observed more frequently among suicide cases than accident cases. However, suicides were not associated with specific combat experiences or military occupation. The extent of combat experience in Vietnam per se as measured in this study is not a good predictor of suicide death.     

Psychological distress and psychiatric diagnoses among primary caregivers of children undergoing hematopoietic stem cell transplant: an examination of prevalence,correlates, and racial/ethnic differences

ObjectiveThe aims of the study were to examine the prevalence of self-reported psychological distress, examine the prevalence of interview-rated psychiatric diagnoses, identify correlates of psychological distress and psychiatric diagnosis and examine racial/ethnic group differences on measures of psychological distress among primary caregivers of children preparing to undergo hematopoietic stem cell transplant (HSCT).MethodsCaregivers (N=215) completed the Beck Anxiety Inventory, Beck Depression Inventory (BDI), Impact of Events Scale, and a psychiatric interview assessing major depressive disorder, generalized anxiety disorder and panic disorder. Regression analyses examined correlates of distress and psychiatric diagnosis. Comparisons were made between racial/ethnic groups.ResultsPosttraumatic stress symptoms were reported by 54% of caregivers during the time preparing for the child's HSCT. Twenty-seven percent of caregivers met diagnostic criteria for at least one of the psychiatric diagnoses during this time. Few factors were associated with distress or psychiatric diagnosis, except the child scheduled for allogeneic transplant, being married and prior psychological/psychiatric care. Sociodemographic factors accounted for racial/ethnic group differences, except that Hispanic/Latino caregivers reported higher BDI scores than non-Hispanic white caregivers.ConclusionCaregivers may be at greater risk of posttraumatic stress symptoms than anxiety or depression. Prior psychological/psychiatric treatment is a risk factor for greater psychological distress and psychiatric diagnosis during this time. Racial differences are mostly due to sociodemographic factors.     

Psychological distress and attitudes of emergency personnel towards suicide attempters

Emergency personnel attitudes towards suicide attempters are important because they have a key role in the management of these patients. We examined the association between staff members' psychological distress and the attitudes towards suicide attempters. We also compared the attitudes towards suicide attempters among emergency personnel between a general and a psychiatric hospital. The Understanding Suicidal Patients (USP) Questionnaire and the 12-item version of General Health Questionnaire were given to all staff in the emergency rooms of a general hospital and a psychiatric hospital (n=151). There was a general tendency among emergency room staff to view attempted suicide patients positively and sympathetically. However, there were clear differences in staff attitudes between the two hospitals: those working in the general hospital expressed more negative attitudes than those in the psychiatric hospital. No evidence emerged of association between staff members' psychological distress and negative attitudes towards suicide attempters. There was no association between psychological distress and negative attitudes towards suicide attempters.     

Effects of combat deployment on risky and self-destructive behavior among active duty military personnel

Although research has documented negative effects of combat deployment on mental health, few studies have examined whether deployment increases risky or self-destructive behavior. The present study addressed this issue. In addition, we examined whether deployment effects on risky behavior varied depending on history of pre-deployment risky behavior, and assessed whether psychiatric conditions mediated effects of deployment on risky behavior. In an anonymous survey, active duty members of the U.S. Marine Corps and U.S. Navy (N = 2116) described their deployment experiences and their participation in risky recreational activities, unprotected sex, illegal drug use, self-injurious behavior, and suicide attempts during three time frames (civilian, military pre-deployment, and military post-deployment). Respondents also reported whether they had problems with depression, anxiety, or PTSD during the same three time frames. Results revealed that risky behavior was much more common in civilian than in military life, with personnel who had not deployed, compared to those who had deployed, reporting more risky behavior and more psychiatric problems as civilians. For the current time period, in contrast, personnel who had deployed (versus never deployed) were significantly more likely to report both risky behavior and psychiatric problems. Importantly, deployment was associated with increases in risky behavior only for personnel with a pre-deployment history of engaging in risky behavior. Although psychiatric conditions were associated with higher levels of risky behavior, psychiatric problems did not mediate associations between deployment and risky behavior. Implications for understanding effects of combat deployment on active duty personnel and directions for future research are discussed.     

Effects of amino acid energy drinks leading to hospitalization in individuals with mental illness

OBJECTIVE: The objective of this case report is to highlight the possible dangers in individuals with prior psychiatric illness of the use of amino acid and caffeine-containing drinks marketed as energy drinks to combat mental and physical fatigue. METHOD: We report on three patients with known psychiatric illness who demonstrated sequelae following use of these beverages with probable association with clinical deterioration leading to hospitalization. RESULTS: In all three cases, hospitalizations were associated with deterioration of mental state, manifested, amongst other symptoms, by hypervigilance, psychomotor unease and intensified affected responses. CONCLUSIONS: While a casual relationship between the use of these drinks and hospitalization cannot be definitively stated, the close temporal association between the two cannot be ignored. Use of these beverages by individuals with prior psychiatric illness should be with caution and the use of energy drinks may be relevant in the patients' evaluations.     

Mental health impact of the Iraq and Afghanistan conflicts: A review of US research,service provision,and programmatic responses

Abstract

Although documentation that war inflicts psychological casualties dates back to the American Civil War and earlier, most research began after the Vietnam conflict, when studies focused on post-traumatic stress disorder (PTSD). With ongoing conflicts in Iraq and Afghanistan, there has been significant research to illuminate the epidemiology of war-related psychological casualties. Significant findings include an appreciation for the role combat plays in the development of mental disorders, including PTSD and traumatic brain injury (TBI). Recent research has endeavoured to understand and improve psychological resilience to temper potentially adverse mental health effects of military service in the theatre of combat operations. Over 2 million US service members have now deployed and returned over 3 million times to the Iraq and Afghanistan conflicts. Mental health providers in the Departments of Defense and Veterans Affairs healthcare systems have consequently observed steep increases in mental health service use among these personnel. The Departments have responded aggressively to bolster staffing levels, increase capacity, improve available services, and anticipate future needs. Scientists and clinicians continue efforts to understand the determinants, prevention, recognition, and treatment of combat-related mental disorders.

Predictability of rehospitalization for schizophrenia

This analysis examines the predictability of the course of schizophrenia using long-term follow-up data on hospital episodes in a cohort of patients from a psychiatric case register in Denmark. We focus on whether clinical and sociodemographic data collected during the first episode are related to the number of hospitalizations during follow-up and the association of patients' course of hospitalizations with the risk of being rehospitalized. A Poisson regression model and a proportional hazards model were used to address these questions. Age of onset and time to the first rehospitalization were strong early predictors of chronicity of course, as measured by the number of psychiatric hospitalizations for each schizophrenic patient. The results also show that the risk of rehospitalization depends on the previous tenures in the community.     

Familial psychiatric illness in chronic posttraumatic stress disorder

One hundred and eight veterans with posttraumatic stress disorder (PTSD) were compared with 60 age-matched controls with regard to family history of psychiatric illness. Depressed controls had a higher morbidity risk (MR) for depression and generalized anxiety in siblings/parents and children, respectively. Patients with PTSD did not differ from alcoholics or nonpsychiatric controls on the basis of family history. PTSD was associated with greater familial anxiety when compared with controls who had experienced combat. When World War II and Vietnam veterans with PTSD were compared, a higher MR for alcohol and drug abuse was found in siblings/parents of Vietnam veterans, and a higher MR was found for other chronic psychiatric disorders in the children of Vietnam veterans.     

Current combat-related disorders in the absence of PTSD among Australian Vietnam veterans

The research literature on the psychiatric consequences of the Vietnam War focuses primarily on the construct of Posttraumatic Stress Disorder (PTSD), after an initial focus in the 1970s on depression and alcohol and substance abuse. The present paper examines the hypothesis that among men without current PTSD, those with higher combat in Vietnam will be more likely to have current DSM-III-R illnesses. The Australian Vietnam Veterans' Health Study (AVVHS) collected a broad range of interview data on 641 Vietnam veterans throughout 1990–1993. Measures of combat exposure, age at embarkation to Vietnam, enlistment IQ and pre-Army personality problems were drawn from Army records of the era. Retrospective measures of combat were obtained at interview. The interview also involved the administration by trained lay interviewers of the DSM-III-R based Diagnostic Interview Schedule (DIS). This epidemiological instrument provides current psychiatric diagnoses as well as temporal (retrospective) symptom and diagnosis onset data. The results of this study show that current disorders (without PTSD comorbidity) with onsets within 5 years of embarkation to Vietnam are more likely among men who saw higher combat, as indexed by combat-exposure measures drawn from Army records of the era as well as retrospective self-report. This combat relatedness remains when age at embarkation, IQ at enlistment and pre-Army personality measures are used as covariates. No more than 11.4% of sampled Vietnam veterans currently meet DSM-III-R diagnostic criteria for PTSD, while a further 7.8% do not have current PTSD but do have some other current DIS diagnosis with onset in the 5-year period following (first) emabarkation to Vietnam. Our data support the hypothesis that the current illnesses of many of these men without PTSD are combat-related DSM-III-R illnesses. Accepted: 11 September 1997     

Demographics of and diagnoses in Operation Enduring Freedom and Operation Iraqi Freedom personnel who were psychiatrically evacuated from the theater of operations

OBJECTIVE: The objective of this study was to characterize the demographic and clinical information of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) military personnel who were psychiatrically evacuated from the theater of operations. METHOD: Records of 1264 consecutive OEF/OIF patients who were medically evacuated for primarily psychiatric reasons between November 4, 2001, and July 30, 2004, were reviewed to collect demographic information and psychiatric diagnoses. RESULTS: When compared with all returned OEF/OIF veterans (N=213,150), psychiatric evacuees were more likely to be: female, under the age of 31 years, African-American or Hispanic, enlisted and National Guard/Reserve. Over 80% of patients were evacuated during the first 6 months, compared with 17% during the second 6 months of deployment. The most common diagnostic categories were adjustment disorders (37.6%), mood disorders (22.1%), personality disorders (15.7%) and anxiety disorders (15.4%); 16.5% received no psychiatric diagnosis. Only 5% of evacuees were returned to OEF/OIF duty. CONCLUSION: Almost half of evacuated patients received no diagnosis or no adjustment disorder diagnosis, suggesting clinical improvement since a decision for evacuation was made. Potential areas of focus for preventing psychiatric evacuations are identifying service members who are at risk during early stages of deployment and studying whether there are gender-specific deployment stressors.
