A prospective study of the impact of floods on the mental and physical health of older adults

Objectives: With a longitudinal prospective design, we examined the impact of floods on the mental and physical health of older adults and explored risk and protective factors.Method: Two hundred and seventy four older adults (age ≥60) completed surveys before and after a flood event. Both the surveys included measures of anxiety, depression, self-reported health, and satisfaction with life; the post-flood survey also included questionnaires on flood experience, symptoms of post-traumatic stress disorder (PTSD), stoicism, and psychological coping with floods.Results: Compared to those not personally affected (78.8%), personally affected individuals (21.2%) reported significantly higher PTSD symptoms, with about one in six reporting PTSD symptoms that might require clinical attention. Personally affected individuals also reported a greater increase in anxiety post-flood, but changes in their depressive symptoms and self-reported health were not significantly different from those not personally affected. Greater flood exposure and the lack of social support were the risk factors for poorer mental and physical health. Higher stoicism was associated with higher post-flood depression and poorer self-reported mental health. The use of maladaptive coping, such as venting and distraction, was associated with greater deterioration in mental health after floods, whilst emotion-focused coping such as acceptance, positive reframing, and humour, was protective against such deterioration.Conclusion: Floods had adverse psychological impacts on some older adults who were personally affected. Despite the evidence of resilience, a small proportion of older adults experienced significant difficulties after the floods. The findings in this study help understand older adults’ psychological responses to disasters and have practical implications for service planning and delivery.

Post-traumatic stress disorder symptomatology and alcohol use among HIV-seropositive adults in Haiti

Psychological trauma resulting from natural disasters can negatively affect the health of persons living with HIV/AIDS (PLWH). This study examined relationships of alcohol use and exposure to the 2010 Haiti earthquake on symptoms of posttraumatic stress disorder (PTSD) among HIV-positive adults enrolled in an intervention study. Baseline data were collected from male and female PLWH, 19–56 years old on: alcohol consumption and related harms; anxiety; and coping strategies used to deal with HIV. Two to three months postearthquake, data were collected from 104 of the study participants on PTSD and earthquake-related impacts. Most participants had less than a secondary education (66%) and very low income (92%≤H$10,000 or≤US$1250/year). Over two-thirds of participants felt at some point that they should cut down on drinking. Fifty-two (50.5%) met criteria for PTSD. More than 83% lost their belongings and 64% had someone close to them hurt or killed during the earthquake. Bivariate analysis showed that women, younger participants, those who lost all belongings, and those with greater overall alcohol impact were more likely to report PTSD symptoms. In the multivariate model, participants more likely to meet PTSD criteria (p<0.05) were those who reported feeling a need to cut down on drinking (OR=3.14, [CI=1.16, 8.49]) and participants who used behavioral disengagement as a coping mechanism (OR=1.49, [CI=1.15, 1.92]). Following a natural disaster, it is important to address trauma-related mental health needs of PLWH – particularly women and individuals who abuse alcohol.

154. Glucocorticoid sensitivity of leukocytes predicts fatigue, depressive, and PTSD symptoms after military deployment

Posttraumatic stress disorder (PTSD), depression and severe fatigue may develop in response to severe stress and trauma. These conditions are associated with altered sensitivity of leukocytes to glucocorticoids (GCs). We investigated whether GC-sensitivity of T-cells and monocytes assessed before military deployment predicts high levels of fatigue, depressive, and/or PTSD symptoms 6 months after return from deployment. We included 523 male military personnel before deployment to Afghanistan. Logistic regression analysis was performed to predict fatigue, depressive, and PTSD symptoms 6 months after deployment based on sensitivity of LPS-induced TNF-alpha production and PHA-induced T-cell proliferation to dexamethasone (DEX)-inhibition before deployment. Severe fatigue 6 months after deployment was independently associated with low DEX-sensitivity of monocyte TNF-α production before deployment. A high level of depressive symptoms 6 months after deployment was independently associated with low DEX-sensitivity of T-cell proliferation. In contrast, a high level of PTSD symptoms after deployment was independently associated with high DEX-sensitivity of T-cell proliferation before deployment, but only in individuals who reported PTSD symptoms without depressive symptoms. DEX-sensitivity was not associated with childhood trauma, a known risk factor for development of fatigue, depressive and PTSD symptoms. GC-sensitivity of leukocytes prior to deployment predicts fatigue, depressive, and PTSD symptomatology in response to deployment. Notably, fatigue, depressive, and PTSD symptoms were differentially associated with GC-sensitivity of monocytes and T-cells and therefore may have specific biological underpinnings.

Glucocorticoid sensitivity of leukocytes predicts PTSD, depressive and fatigue symptoms after military deployment: A prospective study

Posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and severe fatigue may develop in response to severe stress and trauma. These conditions have all been shown to be associated with altered sensitivity of leukocytes for regulation by glucocorticoids (GCs). However, it remains unknown whether sensitivity of leukocytes for GCs is a pre-existing vulnerability factor, or whether GC-sensitivity of leukocytes alters as a consequence of stress and stress-related conditions. Our aim was to investigate whether sensitivity of T-cells and monocytes for regulation by GCs (i.e. dexamethasone: DEX) assessed before military deployment predicts high levels of PTSD, depressive, and/or fatigue symptoms 6 months after return from deployment. We included 526 male military personnel before deployment to Afghanistan. Logistic regression analysis was performed to predict fatigue, depressive, and PTSD symptoms 6 months after deployment based on sensitivity of LPS-induced TNF-α production and PHA-induced T-cell proliferation to DEX-inhibition before deployment. Severe fatigue 6 months after deployment was independently associated with low DEX-sensitivity of monocyte TNF-α production before deployment. A high level of depressive symptoms after deployment was independently associated with a low DEX-sensitivity of T-cell proliferation. In contrast, a high level of PTSD symptoms after deployment was independently associated with a high DEX-sensitivity of T-cell proliferation before deployment, but only in individuals who reported PTSD symptoms without depressive symptoms. The predictive value of DEX-sensitivity was independent of childhood trauma and GR number, GR subtype and GR target gene mRNA expression in leukocytes. We present here for the first time that the sensitivity of leukocytes for GCs prior to deployment is a predictive factor for the development of PTSD, depressive and fatigue symptomatology in response to deployment. Notably, PTSD, depressive and fatigue symptoms were differentially associated with GC-sensitivity of monocytes and T-cells and therefore may have different biological underpinnings.

Post-traumatic disorder symptoms and blunted diurnal cortisol production in partners of prostate cancer patients

Prostate cancer (PC) is the most common cancer diagnosed in men, and research suggests that coping with this illness can cause significant distress in patients as well as their partners. This study examined the relationship of caregiving for a partner with PC with diurnal cortisol output in women between the ages of 42 and 75 years old. Participants were women whose partners had PC (n = 19) and women who were in relationships with men with no diagnosed medical illness (n = 26). Women provided saliva samples (4 times per day over 3 days) in their natural environment. The Structured Clinical Interview for DSM-IV Axis-I Disorders was also conducted to assess for the presence of post-traumatic stress disorder (PTSD) and major depression. Partners of men with PC had lower daily cortisol output across the three days than controls, F(1,444.08) = 20.72, p<.001). They were also more likely to report PTSD symptoms with 68.4% of PC partners fulfilling criteria for sub-threshold PTSD as compared to 23.1% of controls (χ(2) = 11.30, p = .01). Mixed model analyses revealed that the presence of sub-threshold PTSD symptoms significantly predicted cortisol production, F(1,419.64) = 5.10, p<.01). Regardless of caregiver status, women who reported at least sub-threshold PTSD symptoms had lower cortisol production than those with no PTSD symptoms. Major depression did not explain differences in cortisol production between partners of PC patients and controls. Although these findings are preliminary, they highlight the importance of developing interventions aimed at reducing risk of psychopathology in partners of men with PC.

Enhancing entrance into PTSD treatment for post-deployment veterans through collaborative/integrative care

High rates of posttraumatic stress disorder (PTSD) among post-deployment veterans and the associated long-term consequences highlight the importance of early identification and treatment. The Veterans Health Administration (VHA)'s Primary Care Mental Health Integration (PCMHI) program aims to increase identification and access to care for veterans with mental illness, decrease stigma, improve continuity of care, and the efficiency of healthcare utilization. This project examines PCMHI's progress towards these goals within the Operation Iraqi Freedom/Operation Enduring Freedom (OEF/OIF) population. We examined data from consults to the OEF/OIF PTSD clinic for 18months. PCMHI placed 129 consults and 91 (70.5%) were completed. Veterans referred by PCMHI tended to have increased consult completion in specialty care, higher rates of confirmed PTSD, however, no significant differences in reported PTSD symptoms, or follow-up visits in the OEF/OIF PTSD clinic compared to Veterans referred from the hospital at large. PCMHI potentially preserve resources, increases continuity of care, and increases treatment access for OEF/OIF/OND veterans.

Symptoms of Posttraumatic Stress Disorder Among Urban Residents

Previous studies indicate a high risk of Posttraumatic Stress Disorder (PTSD) among women and low-income, urban-residing African-Americans. This study examined PTSD symptoms among urban-residing, socioeconomically diverse, working-age African-Americans and whites. The participants completed the PTSD Checklist-Civilian Version. Of the 2104 participants, 268 (12.7%) were screened positive for PTSD symptoms. Women (13.8%) were more likely than men (11.3%), white participants (13.8%) were more likely than African-Americans (11.9%), and younger participants (16.1%) were more likely than older participants (10.2%) to screen positive for PTSD symptoms. A significant interaction (p = 0.05) revealed that white women living below the 125% poverty level were most likely to report PTSD symptoms. These findings highlight the importance of PTSD screening in low-income urban neighborhoods.

Web-Based Intervention for Returning Veterans with Symptoms of Posttraumatic Stress Disorder and Risky Alcohol Use.

A substantial number of military personnel who have served in Iraq (Operation Iraqi Freedom; OIF) and Afghanistan (Operating Enduring Freedom; OEF) develop symptoms of posttraumatic stress disorder (PTSD) in response to their military experiences and many of these same individuals will drink in a risky or problematic manner following deployment. If left untreated, PTSD symptoms and alcohol problems can become chronic and have a significant, negative impact on the lives of veterans, their families and communities. Further, OIF and OEF service members are often reluctant to seek treatment for mental health symptoms or alcohol problems secondary to stigma. In order to reach this population it is essential that new strategies and venues for delivering evidence-based care are explored. Web-based interventions are uniquely suited to this cohort of veterans in that they have the potential to reach a significant number of veterans who commonly use the Web and who might not otherwise receive care. This article will review the prevalence of PTSD and alcohol problems among OIF and OEF veterans, common barriers they experience with accessing care in traditional mental health settings, and what is known about the effectiveness of Web-based approaches for PTSD and alcohol problems. It also describes the components of a new Web-based intervention, developed by the authors, that uses motivational enhancement and cognitive-behavioral strategies to intervene with returning veterans who report PTSD symptoms and problem drinking. Recommendations for future directions in working with returning veterans with PTSD and alcohol problems will be offered.

Psychological distress in twins with urological symptoms

Objective Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic pain condition with unclear underlying etiology. Our objectives were to determine whether psychological distress was higher in twins with urological symptoms commonly found in IC/PBS than in twins without, and if so, did familial influences contribute to this association. Method Data from 1165 female twins in a community-based sample were used. Urological symptoms, symptoms of posttraumatic stress disorder (PTSD), depression, anxiety and perceived stress were assessed with standardized questionnaires. Generalized estimating equation (GEE) regression models were used to examine the relationship between psychological distress and urological symptoms. Results Compared to unaffected twins, twins with urological symptoms were more likely to report PTSD symptoms (OR=3.9; 95% CI=2.6–5.8), depression (OR=3.1; 95% CI=2.0–5.0), anxiety (OR=3.4; 95% CI=2.3–5.2) and perceived stress (OR=3.2; 95% CI=2.1–4.9). After adjusting for familial influences, the within-pair effects remained significant for PTSD symptoms (OR=2.2; 95% CI=1.2–3.8) and perceived stress (OR=2.2; 95% CI=1.2–3.8). Conclusion Familial influences partially explained the relationship between indicators of psychological distress and urological symptoms. Future research should examine shared environmental and genetic mechanisms that may further explain this relationship and improve diagnosis and treatment of this unexplained clinical condition.

PTSD symptoms and dominant emotional response to a traumatic event: an examination of DSM-IV Criterion A2

To qualify for a diagnosis of posttraumatic stress disorder (PTSD), the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) requires that individuals report experiencing dominant emotions of fear, helplessness, and horror during the trauma (Criterion A2). Despite this stipulation, traumatic events can elicit a myriad of emotions other than fear, such as anger, guilt or shame, sadness, and numbing. The present study examined which emotional reactions to a stressful event in a college student sample are associated with the highest levels of PTSD symptoms. Our results suggest mixed support for the DSM-IV criteria. Although, participants who experienced a dominant emotion of fear reported relatively high PTSD symptomatology, participants who experienced anger, disgust-related emotions, and sadness reported PTSD symptoms of equivalent severity. Additionally, participants reported dominant emotions of sadness and other emotions (including disgust, guilt, and shame) more frequently than they reported fear. These results question the specifics of diagnostic Criterion A2 and may have diagnostic and treatment implications.

Distant Memories

Adopting an observer perspective to recall trauma memories may function as a form of avoidance that maintains posttraumatic stress disorder (PTSD). We conducted a prospective study to analyze the relationship between memory vantage point and PTSD symptoms. Participants (N= 947) identified the vantage point of their trauma memory and reported PTSD symptoms within 4 weeks of the trauma; 730 participants repeated this process 12 months later. Initially recalling the trauma from an observer vantage point was related to more severe PTSD symptoms at that time and 12 months later. Shifting from a field to an observer perspective a year after trauma was associated with greater PTSD severity at 12 months. These results suggest that remembering trauma from an observer vantage point is related to both immediate and ongoing PTSD symptoms.

PTSD Prevalence, Associated Exposures, and Functional Health Outcomes in a Large, Population-Based Military Cohort

Posttraumatic stress disorder (PTSD) results from experiencing or witnessing traumatic, life-threatening events including combat-related experiences. The purpose of this study was to investigate the prevalence of PTSD symptoms and diagnosis, self-reported exposures, and functional health in a large cross-section of the U.S. military. This study used baseline Millennium Cohort data (July 2001 to June 2003) of 75,156 U.S. military members to assess the population-based prevalence of PTSD symptoms, self-reported exposures, and functional health as measured by the Medical Outcomes Study Short Form 36-Item Health Survey for Veterans (SF-36V). PTSD diagnosis without current symptoms was reported by 953 respondents (1.2%, weighted), 1,490 respondents (2.1%, weighted) reported no diagnosis but reported PTSD symptoms, and 287 respondents (0.4%, weighted) reported diagnosis and current symptoms. Self-reported exposure to chemical or biological warfare agents, protective countermeasures, or hearing alarms were associated with PTSD symptoms independent of other combat-like exposures. Physical health was similar among those with PTSD diagnosis and current PTSD symptoms. However, compared with the overall cohort, lower mental health summary means for those reporting current PTSD symptoms (mean = 27.8), current symptoms and diagnosis (mean = 24.6), and diagnosis without current symptoms (mean = 47.5) were found. Results suggest a 2.0% prevalence of PTSD symptoms without diagnosis and that self-reported threatening exposures were significantly associated with PTSD symptoms. Mental and physical health scores of those with current PTSD symptoms appear diminished, but suggest a return to cohort levels with resolution of PTSD symptoms.

To determine whether one population could yield different rates of PTSD, we performed a record review of on-the-record screenings for PTSD conducted at a military facility where an anonymous survey was performed earlier for a research study (3) . In both the anonymous study and clinical screenings, service members were given the PTSD Checklist, Military Version (PCL-M). Since the population and screening instrument were similar, we hypothesized that comparing the anonymous study results with the on-the-record screenings would demonstrate the effect of anonymity in determining the rates of PTSD. Institutional Review Board approval was obtained to perform a chart review at the Naval Medical Center San Diego. This military hospital employs approximately 6,000 health care providers and frequently deploys these individuals to combat zones such as Iraq and Afghanistan. Most of these deployments are in support of Marine Corps operations. Upon returning from deployment, service members participate in a screening that includes the PCL-M. The PCL-M is a self-report instrument that has been validated against clinical criteria and other research measures (4) . It can be scored for broad criteria, which matches the DSM diagnosis, or strict criteria, in which broad criteria are required in addition to a total severity score. At Naval Medical Center San Diego, those individuals who meet broad criteria are encouraged to undergo a diagnostic interview. The number of charts assayed was 408. This number was based on a power estimate intended to detect 50% underreporting for on-the-record screenings by broad criteria. The rates of PTSD by broad and strict criteria were computed using the same methods that were used in the anonymous study (3) . Statistical comparisons were determined using Mann-Whitney tests. A retrospective review of on-the-record screenings in medical personnel returning from Iraq or Afghanistan showed that 32 out of 408 (7.8%) showed broad criteria for PTSD, and 22 out of 408 (5.4%) showed strict criteria. The previous anonymous screen (3) showed that 16 out of 102 (15.7%) service members returning from combat deployments met broad criteria for PTSD, and 9 out of 102 (8.8%) met strict criteria. The relative risk of screening positive for PTSD based on broad criteria was 0.5 when reporting was performed anonymously versus on-the-record. Mann-Whitney tests showed the difference between the rates to be statistically significant for broad criteria (p=0.02). One possibility for these results is that when faced with the consequences of a positive screen for PTSD, service members underreport. However, on-the-record screenings are mandatory for all service members returning from deployment, whereas the anonymous survey required voluntary participation. Thus, it is also possible that 1) those individuals with symptoms to report were more likely to complete the anonymous form and 2) anonymous surveys overreport symptoms. Nevertheless, our results suggest that anonymity plays a role in how individuals report PTSD symptoms. Further outreach is needed to allow those individuals with PTSD to feel safe reporting their symptoms in a way that can connect them to clinical services.San Diego, Calif.The authors report no competing interests.The opinions expressed in this case report are those of the authors and do not reflect the views of the U.S. Department of Defense or the Navy.This letter (doi: 10.1176/appi.ajp.2008.07121960) was accepted for publication in March 2008.

Longitudinal Assessment of Mental Health Problems Among Active and Reserve Component Soldiers Returning From the Iraq War

To promote early identification of mental health problems among combat veterans, the Department of Defense initiated population-wide screening at 2 time points, immediately on return from deployment and 3 to 6 months later. A previous article focusing only on the initial screening is likely to have underestimated the mental health burden. To measure the mental health needs among soldiers returning from Iraq and the association of screening with mental health care utilization. Population-based, longitudinal descriptive study of the initial large cohort of 88 235 US soldiers returning from Iraq who completed both a Post-Deployment Health Assessment (PDHA) and a Post-Deployment Health Re-Assessment (PDHRA) with a median of 6 months between the 2 assessments. Screening positive for posttraumatic stress disorder (PTSD), major depression, alcohol misuse, or other mental health problems; referral and use of mental health services. Soldiers reported more mental health concerns and were referred at significantly higher rates from the PDHRA than from the PDHA. Based on the combined screening, clinicians identified 20.3% of active and 42.4% of reserve component soldiers as requiring mental health treatment. Concerns about interpersonal conflict increased 4-fold. Soldiers frequently reported alcohol concerns, yet very few were referred to alcohol treatment. Most soldiers who used mental health services had not been referred, even though the majority accessed care within 30 days following the screening. Although soldiers were much more likely to report PTSD symptoms on the PDHRA than on the PDHA, 49% to 59% of those who had PTSD symptoms identified on the PDHA improved by the time they took the PDHRA. There was no direct relationship of referral or treatment with symptom improvement. Rescreening soldiers several months after their return from Iraq identified a large cohort missed on initial screening. The large clinical burden recently reported among veterans presenting to Veterans Affairs facilities seems to exist within months of returning home, highlighting the need to enhance military mental health care during this period. Increased relationship problems underscore shortcomings in services for family members. Reserve component soldiers who had returned to civilian status were referred at higher rates on the PDHRA, which could reflect their concerns about their ongoing health coverage. Lack of confidentiality may deter soldiers with alcohol problems from accessing treatment. In the context of an overburdened system of care, the effectiveness of population mental health screening was difficult to ascertain.

Associations of pre-trauma attributes and trauma exposure with screening positive for PTSD: analysis of a community-based study of 2085 young adults

While pre-trauma personality and mental health measures are risk factors for post-traumatic stress disorder (PTSD), such information is usually obtained following the trauma and can be influenced by post-trauma distress. We used data collected from a community-based survey of young adults before and after a major natural disaster to examine the extent to which participants' traumatic experiences, demographic and pre-trauma risk factors were associated with their screening positive for PTSD when re-interviewed. A representative selection of 2,085 young adults from the Australian Capital Territory and environs, interviewed in 1999 as part of a longitudinal community-based survey, were re-interviewed 3-18 months after a major bushfire had occurred in the region. When re-interviewed, they were asked about their experiences of trauma threat, uncontrollable and controllable traumatic experiences and their reaction to the fire. They were also screened for symptoms of fire-related PTSD experienced in the week prior to interview. Four-fifths of participants were exposed to the trauma with around 50% reporting having experienced uncontrollable traumatic events. Reporting PTSD symptoms was associated with being female, having less education, poorer mental health and higher levels of neuroticism prior to the trauma. Particular fire experiences, including being evacuated and feeling very distressed during the disaster, were more strongly associated with PTSD symptoms compared with pre-trauma measures. While demographic and pre-trauma mental health increased the likelihood of reporting PTSD symptoms, exposure to trauma threat and reaction to the trauma made greater contributions in explaining such symptoms as a result of this disaster.

Effects of Trauma Exposure on Anger, Aggression, and Violence in a Nonclinical Sample of Men

This study assessed the impact of traumatic exposure and posttraumatic stress disorder (PTSD) symptoms on anger, aggression, and violence among civilian male college students. Results suggest that civilian men who have been exposed to a potentially traumatic event (PTE) and report symptoms of PTSD indicate more trait anger, more internal anger and hostility, and more aggression and violence than men who do not report symptoms of PTSD. Results are contrasted to those found in clinical samples of male veterans with PTSD and discussed in terms of understanding and treating anger and aggression in non-clinical, trauma-exposed populations.

Violence Exposure, Posttraumatic Stress Disorder, and Depressive Symptoms Among Recent Immigrant Schoolchildren

Many recent immigrant children are at risk for violence exposure and related psychological distress resulting from experiences before, during, and after immigration. This study examines the rates of violence exposure and associated symptoms among recent immigrant children in Los Angeles. 1,004 recent immigrant schoolchildren (aged 8-15 years) were surveyed about their prior exposure to violence and symptoms of posttraumatic stress disorder (PTSD) and depression. Participants included children whose native language was Spanish, Korean, Russian, or Western Armenian. Participants reported high levels of violence exposure, both personal victimization and witnessing violence, in the previous year and in their lifetimes. Thirty-two percent of children reported PTSD symptoms in the clinical range, and 16% reported depressive symptoms in the clinical range. Although boys and older children were more likely to have experienced violence, girls reported more PTSD and depressive symptoms. Linear multiple regressions revealed that PTSD symptoms were predicted by both recent and lifetime violence exposure (p values < .001 and p < .05, respectively), when depressive symptoms and gender were controlled. On the other hand, depressive symptoms were predicted by recent victimization only (p < .001) when PTSD and gender were controlled. These findings document the need for interventions addressing the psychological sequelae of violence exposure in immigrant children.

Posttraumatic Stress Two Years after the Oklahoma City Bombing in Youths Geographically Distant from the Explosion

This article describes Posttraumatic Stress Disorder (PTSD) symptomatology in 69 sixth-grade youths who resided within 100 miles of Oklahoma City at the time of the 1995 bombing of the Alfred P. Murrah Federal Building. These youths neither had any direct physical exposure nor personally knew anyone killed or injured in the explosion. A survey conducted two years after the bombing assessed exposure, PTSD symptoms, and functioning. PTSD symptom frequency was measured with the Impact of Event Scale--Revised. Our BCD criteria for defining PTSD caseness was modeled after DSM-IV B, C, and D criteria requiring one reexperiencing, three avoidance/numbing, and two arousal symptoms for diagnosis. Those who met our BCD criteria had significantly higher PTSD symptom scores than those who did not. Both increased mean PTSD symptom score and meeting our caseness definition were associated with increased functioning difficulties. Media exposure and indirect interpersonal exposure (having a friend who knew someone killed or injured) were significant predictors of symptomatology. These findings suggest that children geographically distant from disaster who have not directly experienced an interpersonal loss report PTSD symptoms and functional impairment associated with increased media exposure and indirect loss.
