Sample and design considerations in post-disaster mental health needs assessment tracking surveys

Work-related posttraumatic stress disorder in paramedics in comparison to data from the general population of working age. A systematic review and meta-analysis

Objective

Paramedics are at particularly high risk for developing posttraumatic stress disorders (PTSD). Hitherto, evidence for higher prevalence rates in paramedics compared to the general population is vague. We aimed to determine and compare 12-month prevalence of PTSD in paramedics and general population from high-income countries.

Methods

We conducted systematic review processes to identify relevant studies for inclusion. For paramedics, we searched relevant databases, reference lists, and did citation tracking. Inclusion criteria were applied according to PICO. Quality of the studies was assessed using a validated methodological rating tool. Twelve-month prevalence data from all studies were pooled using random effects model. Subgroup analyses were performed to identify sources of heterogeneity.

Results

In total, we found 41 distinct samples with 17,045 paramedics, 55 samples with 311,547 individuals from non-exposed general population, 39 samples with 118,806 individuals from populations affected by natural disasters, and 22 samples with 99,222 individuals from populations affected by human-made disasters. Pooled 12-month prevalence estimates of PTSD were 20.0, 3.1, 15.6, and 12.0%, respectively. Prevalence estimates in paramedics varied with methodological quality and measurement instrument. Paramedics reporting distinct critical incidences had lower pooled prevalence than paramedics reporting indistinct types of exposure.

Conclusion

Paramedics have a pooled prevalence of PTSD that is considerably higher than rates of unexposed general population and populations affected by human-made disasters. Chronic exposure to low-threshold traumatic events during daily routine work is a risk factor for developing PTSD. Strategies to ensure long working lifetime are strongly needed.

Design and Implementation of the Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic Disease Trends (PROSPECT)

The Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic Disease Trends (PROSPECT) is a prospective cohort study in Puerto Rico (PR) aiming to identify trends and longitudinal associations in risk factors for cardiovascular disease (CVD). In 2019, PROSPECT investigators started recruiting a sample of 2,000 adults aged 30-75 years in PR using multistage probabilistic sampling of households and community approaches. Culturally sensitive trained research assistants assess participants, at baseline and at 2-year follow-up, in private rooms at a network of partner clinics. The study collects comprehensive data on demographic factors, socioeconomic and environmental factors, medical history, health conditions, lifestyle behaviors, psychosocial status, and biomarkers of CVD and stress. PROSPECT will estimate the prevalence and incidence of psychosocial, lifestyle, and biological CVD risk factors, describe variations in risk factors by urbanicity (urban areas vs. rural areas) and exposure (before and after) to natural disasters, and determine predictors of longitudinal changes in CVD risk factors. The study has 4 coordinated operational strategies: 1) research productivity (including synergy with existing epidemiologic cohorts of Hispanics/Latinos for comparison); 2) research infrastructure (biorepository, ancillary studies, and clinical research network); 3) capacity-building, education, and training; and 4) community outreach, dissemination, and policy. PROSPECT will inform public health priorities to help reduce CVD in PR.

Trajectories of Posttraumatic Stress in Youths After Natural Disasters

IMPORTANCE

Disaster exposure is associated with the development of posttraumatic stress (PTS) symptoms in youths. However, little is known about how to predict which youths will develop chronic PTS symptoms after disaster exposure.

OBJECTIVE

To evaluate PTS symptom trajectories among youths after 4 major US hurricanes and assess factors associated with those trajectories.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study used integrative data analysis to combine data from 4 studies of youths' responses to natural disasters (hurricanes Andrew [1992], Charley [2004], Ike [2005], and Katrina [2008]) at time points ranging from 3 to 26 months after the disasters. Those studies recruited and surveyed youths aged 6 to 16 years at schools via convenience sampling of schools near the path of destruction for each hurricane. This study was conducted from August 2017 to August 2020, and pooled data were analyzed from February 2019 to October 2020.

EXPOSURE

Experience of a natural disaster during the ages of 6 to 16 years.

MAIN OUTCOMES AND MEASURES

Posttraumatic stress symptoms were assessed using the University of California, Los Angeles, Posttraumatic Stress Disorder Reaction Index (UCLA PTSD-RI) and the UCLA PTSD-RI-Revised. Latent class growth analyses were used to evaluate the youths' PTS symptom trajectories and associated factors.

RESULTS

Among 1707 youths included in the study, the mean (SD) age was 9.61 (1.60) years, 922 (54%) were female, and 785 (46%) self-identified as White non-Hispanic. Four PTS symptom trajectories were identified: chronic (171 participants [10%]), recovery (393 [23%]), moderate-stable (563 [33%]), and low-decreasing (580 [34%]). Older youths were less likely to be in the chronic group; compared with the chronic group, each 1-year increase in age was associated with increased odds of being in the other groups (recovery: odds ratio [OR], 1.78 [95% CI, 1.29-2.48]; moderate-stable: OR, 1.94 [95% CI, 1.43-2.62]; and low-decreasing: OR, 2.71 [95% CI, 1.99-3.71]). Compared with males, females had higher odds of being in the chronic group than in any other group (recovery group: OR, 0.48 [95% CI, 0.26-0.91]; moderate-stable group: OR, 0.37 [95% CI, 0.21-0.64]; and low-decreasing group: OR, 0.25 [95% CI, 0.14-0.44]).

CONCLUSIONS AND RELEVANCE

In this cohort study, few youths reported chronic distress, and trajectories among most youths reflected recovery or low-decreasing PTS symptoms. Older age and identification as male were factors associated with decreased odds of a chronic trajectory. Youths with chronic or moderate-stable trajectories may benefit from intervention.

State medical marijuana laws, cannabis use and cannabis use disorder among adults with elevated psychological distress

BACKGROUND

Cannabis use and cannabis use disorder are more prevalent in U.S. states with medical marijuana laws (MMLs), as well as among individuals with elevated psychological distress. We investigated whether adults with moderate and serious psychological distress experienced greater levels of cannabis use and/or disorder in states with MMLs compared to states without MMLs.

METHODS

National Survey of Drug Use and Health data (2013-2017) were used to compare past-month cannabis use, daily cannabis use, and cannabis use disorder prevalence among adults with moderate and serious psychological distress in states with versus without MMLs. We executed pooled multivariable logistic regression analyses to test main effects of distress, MMLs and their interaction, after adjustment.

RESULTS

Compared to states without MMLs, states with MMLs had higher adjusted prevalence of past-month use (11.1 % vs. 6.8 %), daily use (4.0 % vs. 2.2 %), and disorder (1.7 % vs. 1.2 %). Adults with moderate and serious psychological distress had greater adjusted odds of any use (AORs of 1.72 and 2.22, respectively) and of disorder (AORs of 2.17 and 2.94, respectively), compared to those with no/mild distress. We did not find evidence of an interaction between MMLs and distress category for any outcome.

CONCLUSIONS

Associations between elevated distress and cannabis use patterns are no greater in states with MML. However, cannabis use is more prevalent in MML states. Thus, higher base rates of cannabis use and disorder among adults with elevated distress are proportionally magnified in these states.

Mental Health Services and Personal Recovery in California: A Population-Based Analysis

OBJECTIVE

Personal recovery measures have been examined among treatment-seeking individuals enrolled in high-quality care. The authors examined whether utilization of mental health services as typically delivered is associated with personal recovery among adults with clinically significant psychological distress.

METHODS

The Kessler Psychological Distress Scale (K-6) measured respondents' (N=1,954) psychological distress level. The authors also assessed five dimensions of personal recovery-hope, life satisfaction, empowerment, connectedness, and internalized stigma. Multivariable linear regression analyses were used to examine relationships between personal recovery and treatment, self-reported treatment completion, provider type, and adequacy of care, adjusting for covariates including K-6 score.

RESULTS

Participants who received care >12 months prior to the survey reported lower levels of hope (95% confidence interval [CI]=-0.36, -0.06, p<0.01), empowerment (95% CI=-0.26, -0.02, p<0.05), and connectedness (95% CI=-0.37, -0.06, p<0.01) than those who had not received treatment. Those who received care in the past 12 months reported lower levels of hope (95% CI=-0.47, -0.14, p<0.001) and life satisfaction (95% CI=-0.42, -0.05, p<0.01). However, treatment completion was associated with higher levels of empowerment (95% CI=0.02, 0.56, p<0.05) and hope (95% CI=0.04, 0.62, p<0.05) and lower levels of stigma (95% CI=-1.21, -0.21, p<0.01) compared with noncompletion. Differences according to provider type and adequacy of care were nonsignificant.

CONCLUSIONS

Utilization of mental health services was associated with lower levels of personal recovery, which may indicate that care-as typically utilized and received-does not promote personal recovery. Longitudinal research is needed to determine causal relationships underlying these associations.

Modification of the risk of post-traumatic stress disorder (PTSD) by the 5-HTTLPR polymorphisms after Lorca's earthquakes (Murcia, Spain)

Information of the modulation effect of the serotonin transporter gene-linked polymorphic region (5-HTTLPR) on post-traumatic stress disorder (PTSD) after earthquakes is scarce and contradictory. A cross-sectional face-to-face interview survey of a representative sample of the adults was carried out after the Lorca (Spain) earthquakes (May 11, 2011). Socio-demographic variables, DSM-IV diagnostic assessment and earthquake-related stressors were obtained from the Composite International Diagnostic Interview (CIDI). The triallelic and biallelic classification of the 5-HTTLPR polymorphism were genotyped from buccal swabs. Multivariate logistic regression models were used to predict PTSD, including interaction terms to explore gene-environment (G x E) interactions. The vast majority (83%, n = 341) of the Lorca survey respondents (n = 412, 71% response rate) were genotyped. Both classifications of the 5-HTTLPR genotype were in Hardy-Weinberg equilibrium. Prior lifetime PTSD was the only variable that remained a significant predictor after adjustments. There were no significant main effects of earthquake related stressors or 5-HTTLPR. However, G x E interactions of 5-HTTLPR with high emotional impact and prior lifetime anxiety disorders were statistically significant. These results provide new evidence of the modulation effect of the 5-HTTLPR polymorphisms on PTSD risk. This information might characterize people at higher risk of developing PTSD after an earthquake exposure.

Concerns and future preparedness plans of a vulnerable population in New Jersey following Hurricane Sandy

Knowing how people prepare for disasters is essential to developing resiliency strategies. This study examined recalled concerns, evacuation experiences, and the future preparedness plans of a vulnerable population in New Jersey, United States, following Hurricane Sandy in 2012. Understanding the responses of minority communities is key to protecting them during forthcoming disasters. Overall, 35 per cent of respondents were not going to prepare for an event. Intended future preparedness actions were unrelated to respondents' ratings of personal impact. More Blacks and Hispanics planned on preparing than Whites (68 versus 55 per cent), and more Hispanics planned on evacuating than did others who were interviewed. A higher percentage of respondents who had trouble getting to health centres were going to prepare than others. Respondents' concerns were connected to safety and survival, protecting family and friends, and having enough food and medicine, whereas future actions included evacuating earlier and buying sufficient supplies to shelter in place.

Social Marketing of Mental Health Treatment: California's Mental Illness Stigma Reduction Campaign

Objectives. To understand the processes involved in effective social marketing of mental health treatment. Methods. California adults experiencing symptoms of probable mental illness were surveyed in 2014 and 2016 during a major stigma reduction campaign (n = 1954). Cross-sectional associations of campaign exposure with stigma, treatment overall, and 2 stages of treatment seeking (perceiving a need for treatment and use conditional on perceiving a need) were examined in covariate-adjusted multivariable regression models. Results. Campaign exposure predicted treatment use overall (odds ratio [OR] = 1.82; 95% confidence interval [CI] = 1.17, 2.83). Exposure was associated with perceived need for services (OR = 1.64; 95% CI = 1.09, 2.47) but was not significantly associated with treatment use in models conditioned on perceiving a need (OR = 1.52; 95% CI = 0.78, 2.96). Exposure was associated with less stigma, but adjustment for stigma did not affect associations between exposure and either perceived need or treatment use. Conclusions. The California campaign appears to have increased service use by leading more individuals to interpret symptoms of distress as indicating a need for treatment. Social marketing has potential for addressing underuse of mental health services and may benefit from an increased focus on perceived need.

Ethnic differences in risk: experiences, medical needs, and access to care after hurricane Sandy in new jersey

This survey investigation assessed an economically challenged and largely minority population regarding concerns, evacuation status, medical needs and access to care during, and after, Hurricane Sandy by ethnicity status for patients using New Jersey's Federally Qualified Health Centers (FQHC). Data obtained contribute to understanding risk from disasters, and improving environmental justice for vulnerable populations following disasters. FQHCs provide medical and dental services for 5% of New Jersey 's population; 95% of those served are uninsured, underinsured, or live below the poverty level. Economically vulnerable individuals are more at risk and were disproportionately harmed by Sandy. There were ethnic differences in days evacuated, days without power and heat, self-rating of personal/family impact, center use, need and access, and interruptions of care and medications. Hispanics and Blacks reported needing centers significantly more than White population. Primary medical conditions were diabetes, asthma, hypertension, and arrhythmia and heart disease, which did not vary ethnically. Understanding medical needs and concerns of vulnerable populations may help policymakers and practitioners prepare and respond promptly to disasters, reducing risk, and building resiliency for the medical care system.

Earthquakes, attributions, and psychopathology: a study in a rural community

Background: Attributions of both cause and blame form part of the diagnostic criteria for PTSD in DSM-5. Most work on attributions and psychopathology has focused on survivors of interpersonal violence and the two types of attribution have not been investigated together in natural disaster contexts. Previous work has identified that attributions to God's role may be associated with survivors' mental health following disasters. We studied the relation between attributions to God and other actors/entities in a rural community with high levels of religiosity that had suffered extensive damage and loss of life due to a series of earthquakes. Methods: A sample of survivors (N = 127) was assessed for degree of earthquake exposure, resource loss, attributions of cause and blame for the earthquake damage, and psychopathology three months after a series of major earthquakes in Italy. Results: Nature and chance were associated with higher cause than blame attributions whereas the State, the municipality, building firms, and the mafia were associated with higher blame than cause attributions. Additionally, both cause and blame attributions towards God and chance were positively correlated with PTSD and psychological distress symptoms. These associations remained significant while controlling for degree of earthquake exposure, resource loss, gender, age, and education. Conclusion: The current study supports the role played by cognitions about the cause of traumatic events, as introduced into the PTSD diagnosis in DSM-5, and extends this to blame of other entities such as God and chance following disasters.

Differential Association of Stigma with Perceived Need and Mental Health Service Use

This study examined the role of stigma at two stages of the treatment-seeking process by assessing associations between various types of stigma and perceived need for mental health treatment as well as actual treatment use. We analyzed cross-sectional data from the 2014 and 2016 California Well-Being Survey, a telephone survey with a representative sample of 1954 California residents with probable mental illness. Multivariable logistic regression indicated that perceived need was associated with less negative beliefs about mental illness (odds ratio [OR] = 0.72; 95% confidence interval [CI] = 0.54, 0.95) and greater intentions to conceal a mental illness (OR = 1.47; 95% CI = 1.12-1.92). Among respondents with perceived need, treatment use was associated with greater mental health knowledge/advocacy (OR = 1.63; 95% CI = 1.03-2.56) and less negative treatment attitudes (OR = 0.66; 95% CI = 0.43-1.00). Understanding which aspects of stigma are related to different stages of the help-seeking process is essential to guiding policy and program initiatives aimed at ensuring individuals with mental illness obtain needed mental health services.

The relationship between social support and posttraumatic stress symptoms among youth exposed to a natural disaster

Background: Children are a vulnerable population following a natural disaster, due to their age and dependence on adults. The primary presenting problem children report after disasters is posttraumatic stress symptoms (PTSS). Prior research suggests that PTSS is inversely related to social support, which is often disrupted after a disaster. Objective: This study examined the relationship between social support (from parents, teachers, and peers) and PTSS in children affected by Hurricane Katrina. The research contributes to the literature by examining the mechanisms that drive this relationship over time. Methods: In this study, 426 children were followed over four timepoints, beginning 3-7 months after Hurricane Katrina and concluding 25-27 months post-hurricane. Three path models analysed the relationship between social support (from parents, teachers, and peers, measured by the Social Support Scale for Children) and PTSS (measured by the UCLA PTSD Reaction Index). Covariates included child age, minority status, gender, perceived life threat, and actual life threat. Nonsignificant paths were trimmed from the final models. Global fit indices were examined to determine model fit. Results: In the parent and peer social support models, PTSS exhibited statistically significant effects on social support from one wave to the next. In the teacher model, this was only true between Waves 2 and 3. Social support showed a statistically significant effect on PTSS between Wave 2 and Wave 3 in the peer model (standardized estimate = -0.26, p < .0001). No paths from social support to PTSS were significant in the parent and teacher models. Conclusion: Findings support a social selection model in which PTSS undermine social support, particularly in the first two years post-disaster. If these findings are replicated, this suggests that, in cases of limited funding, PTSS should be prioritized, given their cascading effects on social support.

Post-Traumatic Stress Disorder and other mental disorders in the general population after Lorca's earthquakes, 2011 (Murcia, Spain): A cross-sectional study

AIMS

To describe the prevalence and severity of mental disorders and to examine differences in risk among those with and without a lifetime history prior to a moderate magnitude earthquake that took place in Lorca (Murcia, Spain) at roughly the mid-point (on May 11, 2011) of the time interval in which a regional epidemiological survey was already being carried out (June 2010 -May 2012).

METHODS

The PEGASUS-Murcia project is a cross-sectional face-to-face interview survey of a representative sample of non-institutionalized adults in Murcia. Main outcome measures are prevalence and severity of anxiety, mood, impulse and substance disorders in the 12 months previous to the survey, assessed using the Composite International Diagnostic Interview (CIDI 3.0). Sociodemographic variables, prior history of any mental disorder and earthquake-related stressors were entered as independent variables in a logistic regression analysis.

FINDINGS

A total number of 412 participants (response rate: 71%) were interviewed. Significant differences in 12-month prevalence of mental disorders were found in Lorca compared to the rest of Murcia for any (12.8% vs 16.8%), PTSD (3.6% vs 0.5%) and other anxiety disorders (5.3% vs 9.2%) (p≤ 0.05 for all). No differences were found for 12-month prevalence of any mood or any substance disorder. The two major predictors for developing a 12-month post-earthquake mental disorder were a prior mental disorder and the level of exposure. Other risk factors included female sex and low-average income.

CONCLUSIONS

PTSD and other mental disorders are commonly associated with earthquake disasters. Prior mental disorders and the level of exposure to the earthquakes are the most important for the development of a consequent mental disorder and this recognition may help to identify those individuals that may most benefit from specific therapeutic intervention.

Responses of a vulnerable Hispanic population in New Jersey to Hurricane Sandy: Access to care, medical needs, concerns, and ecological ratings

Recent increases in hurricanes led to a need to evaluate access to medical care, medical needs, and personal and community impact on vulnerable populations, particularly elderly, low income, and minority communities. This investigation examined (1) access to care, (2) interruptions in medical services, (3) personal impact from Hurricane Sandy, and (4) agreement with ecological statements related to storms, flooding, and damages in Hispanic/Latino patients receiving health care at Federally Qualified Health Centers in New Jersey. Only 10% of 335 Hispanic interviewees were US born. Self-identified personal impact was a better indicator of effects from Sandy, health center use, and medical issues, than community impact rating. Respondents who provided a high personal impact rating were more likely to have evacuated, had longer power outage, were more likely to need medical care, displayed more trouble getting to centers, and exhibited more medical interruptions during Sandy. A higher % respondents who evacuated, needed the center, had trouble getting there, and had more "medical need" than those who did not evacuate. The greatest impacts were on respondents who were told to evacuate before the storm, but did not (46% had "medical need"). The respondents had high agreement ratings for "storms are due to climate change," followed by "frequent and stronger storms will come more often," "flooding is due to sea level rise," and "changing climate is due mainly to human activity and not natural causes". These ratings may aid public policymakers and planners in developing resiliency strategies for vulnerable coastal communities.

Perceptions of distress and positive consequences following exposure to a major disaster amongst a well-studied cohort

OBJECTIVES

Research on the impact of natural disasters on health and well-being faces several methodological challenges, including: sampling issues; exposure assessment; and outcome measurement. The present study used a comprehensive measure of disaster exposure to assess relationships between exposure to the Canterbury (New Zealand) Earthquakes of 2010-2011 and both: (a) self-reported distress and (b) positive outcomes; and also investigated gender differences in reports.

METHODS

Data were gathered from the Christchurch Health and Development Study, a 35-year longitudinal study. The study examined data from 495 individuals exposed to the Canterbury Earthquakes for who complete data on exposure and reactions to the earthquakes at age 35 were available.

RESULTS

Participants with higher levels of exposure to the earthquakes reported significantly (p<0.0001) higher levels of distress due to fear, death and injury, and disruption caused by the earthquakes. Higher levels of exposure to the earthquakes were also associated with significantly (p<0.0001) higher levels of reporting positive consequences following the earthquakes. Women reported significantly (p<0.0001) greater distress than men and significantly (p<0.001) greater positive consequences.

CONCLUSIONS

Higher levels of exposure to disaster were associated with higher levels of distress, but also with higher levels of self-reported positive outcomes, with females reporting higher levels of both positive and negative outcomes. The findings highlight the need for comprehensive assessment of disaster exposure, to consider gender and other group differences in reactions to disaster exposure, and for studies of disasters to examine both positive and negative consequences.

The design of a survey questionnaire to measure perceptions and behaviour during an influenza pandemic: the Flu TElephone Survey Template (FluTEST)

Background

During the 2009–10 influenza (flu) pandemic, surveys to assess behaviour among the general public were designed quickly and suffered from methodological deficits as a result. To facilitate survey work in a future pandemic we (1) identified variables relating to behaviour, perceptions and presence of symptoms that were of relevance to policy-makers and other public health experts; (2) tested and refined the wording of questions to measure these variables; (3) assessed the reliability of responses to these questions; and (4) tested whether non-response bias due to attrition might prevent the use of a longitudinal design for future pandemic-related surveys.

Objective

To design, test and refine a set of questions to assess perceptions and behaviours in relation to a pandemic flu outbreak.

Method

We identified variables via existing systematic reviews and through consultation with pandemic flu planners from Public Health England, the English Department of Health, their advisory groups and academic colleagues. We adapted questions from existing scales or developed them afresh, and tested their clarity in three rounds of qualitative interviews with members of the public (totaln = 78). We used a random-digit dial telephone survey of adults from Great Britain (n = 1080) to assess the internal reliability of scales. We used a follow-up survey 1–2 weeks later to assess the test–retest reliability of responses and the differences between responders (n = 621) and non-responders (n = 459).

Results

We identified seven core sets of outcome variables relating to the presence of flu-like illness and to various protective behaviours, as well as a set of likely predictor variables for the behaviours. Qualitative interviews identified multiple issues with our questions, most of which we resolved. Reliability of the items was largely satisfactory. Evidence of non-response bias was found, with non-responders being younger and less well educated than responders, and differing on several flu-related variables.

Conclusions

It would be ill-advised for public health bodies to enter the next pandemic without a plan for how to measure the public’s behaviours and perceptions. The extensive set of items that we compiled as part of this work has the benefit of being evidence based, policy relevant and readily understood. Although choosing how to gather data still requires consideration, these items can be used with confidence as soon as the next pandemic begins. Future work should consider the most appropriate method for conducting surveys using these items.

The role of applied epidemiology methods in the disaster management cycle

Disaster epidemiology (i.e., applied epidemiology in disaster settings) presents a source of reliable and actionable information for decision-makers and stakeholders in the disaster management cycle. However, epidemiological methods have yet to be routinely integrated into disaster response and fully communicated to response leaders. We present a framework consisting of rapid needs assessments, health surveillance, tracking and registries, and epidemiological investigations, including risk factor and health outcome studies and evaluation of interventions, which can be practiced throughout the cycle. Applying each method can result in actionable information for planners and decision-makers responsible for preparedness, response, and recovery. Disaster epidemiology, once integrated into the disaster management cycle, can provide the evidence base to inform and enhance response capability within the public health infrastructure.

Concerns and perceptions immediately following Superstorm Sandy: ratings for property damage were higher than for health issues

Governmental officials, health and safety professionals, early responders, and the public are interested in the perceptions and concerns of people faced with a crisis, especially during and immediately after a disaster strikes. Reliable information can lead to increased individual and community preparedness for upcoming crises. The objective of this research was to evaluate concerns of coastal and central New Jersey residents within the first 100 days of Superstorm Sandy's landfall. Respondents living in central New Jersey and Jersey shore communities were differentially impacted by the storm, with shore residents having higher evacuation rates (47% vs. 13%), more flood waters in their homes, longer power outages (average 23 vs. 6 days), and longer periods without Internet (29 vs. 6 days). Ratings of concerns varied both among and within categories as a function of location (central vs. coastal New Jersey), stressor level (ranging from 1 to 3 for combinations of power outages, high winds, and flooding), and demographics. Respondents were most concerned about property damage, health, inconveniences, ecological services, and nuclear power plants in that order. Respondents from the shore gave higher ratings to the concerns within each major category, compared to those from central Jersey. Four findings have implications for understanding future risk, recovery, and resiliency: (1) respondents with the highest stressor level (level 3) were more concerned about water damage than others, (2) respondents with flood damage were more concerned about water drainage and mold than others, (3) respondents with the highest stressor levels rated all ecological services higher than others, and (4) shore respondents rated all ecological services higher than central Jersey residents. These data provide information to design future preparedness plans, improve resiliency for future severe weather events, and reduce public health risk.

Health concerns and perceptions of central and coastal New Jersey residents in the 100 days following Superstorm Sandy

Superstorm Sandy made landfall in New Jersey 29-30 October 2012 (130 km/h winds), and many residents were evacuated, were without power for days to several weeks, and suffered property damages or lost their homes. The objective of this study was to understand health concerns within 100 days of this devastating storm that might improve recovery, future preparedness, and resilience. We conducted a survey of New Jersey residents in central (N=407) and shore communities (n=347) about health concerns before, during, and after Superstorm Sandy. People were interviewed at public places, town hall and FEMA meetings, health and university centers, and other gathering places. 47% of shore and 13% of central Jersey respondents evacuated. Both populations were concerned about agents of destruction, survival needs, and possessions before and during the storm, but they were mainly concerned about survival needs thereafter. During the storm, medical issues were the greatest concern for shore respondents (23%) vs secure and safe food and water (29%) for central respondents. Medical concerns increased after the storm. In the future, 42% of shore respondents would prepare more, while 51% of central residents would buy more supplies; 20% (shore) and 11% (central) would heed future evacuation warnings. Before Sandy many residents did not heed warnings and evacuation orders, but worried about property damage, while during and after their major concerns were personal and community health. Prevention of future health and property impacts could be enhanced by stronger evacuation enforcement, better preparedness information, greater attention to the possibility of prolonged power outages, and more attention to medical needs during and after a storm.

Behavioral health and disasters: looking to the future

Along with other manmade and natural disasters, oil spills produce profound and long-term impacts on the behavioral health of their survivors. Although previous and ongoing research has focused on producing evidence of the breadth and depth of these impacts, future efforts must begin to translate this evidence into developing and implementing policies, programs, and practices that effectively contribute to their prevention and mitigation. Drawing upon a conceptual framework of the behavioral health impacts of oil spills developed from data collected in the aftermath of the Exxon Valdez oil spill in 1989, this paper examines potential interventions designed to prevent or mitigate biopsychosocial, interpersonal, and intrapersonal impacts on behavioral health. Future efforts to translate behavioral health research into effective practice will require the formation and maintenance of academic-community partnerships for the purpose of building resilience to these impacts and providing targeted services to those most vulnerable to their long-term consequences.

Neurobehavioral Mechanisms of Traumatic Stress in Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a debilitating psychiatric disorder that develops following trauma exposure. It is characterized by four symptom clusters: intrusion, avoidance, negative alteration in cognitions and mood, and alterations in arousal and reactivity. Several risk factors have been associated with PTSD, including trauma type and severity, gender and sexual orientation, race and ethnicity, cognitive reserve, pretrauma psychopathology, familial psychiatric history, and genetics. Great strides have been made in understanding the neurobiology of PTSD through animal models and human imaging studies. Most of the animal models have face validity, but they have limitations in the generalization to the human model of PTSD. Newer animal models, such as the "CBC" model, have better validity for PTSD, which takes into account the different components of its diagnostic criteria. To date, fear conditioning and fear extinction animal models have provided support for the hypothesis that PTSD is a dysregulation of the processes related to fear regulation and, especially, fear extinction. More research is needed to further understand these processes as they relate not only to PTSD but also to resilience. Further, this research could be instrumental in the development of novel effective treatments for PTSD.

The psychological and psychiatric effects of terrorism: lessons from London

The 7 July 2005 bombings in London caused heightened levels of distress among some in the general community. This distress was most notable in Muslims and members of ethnic minority groups. These effects were transient for most. An estimated 30% of those who were more affected by the attacks, including victims and witnesses, developed psychiatric disorders as a result. An outreach program was set up to screen those who were exposed to potentially traumatic events and to offer them evidence-based treatment. This article discusses what lessons might be learned from studies of the general community and the screen-and-treat approach.

Research Methods in Child Disaster Studies: A Review of Studies Generated by the September 11, 2001, Terrorist Attacks; the 2004 Indian Ocean Tsunami; and Hurricane Katrina

BACKGROUND

A comprehensive review of the design principles and methodological approaches that have been used to make inferences from the research on disasters in children is needed.

OBJECTIVE

To identify the methodological approaches used to study children's reactions to three recent major disasters-the September 11, 2001, attacks; the 2004 Indian Ocean Tsunami; and Hurricane Katrina.

METHODS

This review was guided by a systematic literature search.

RESULTS

A total of 165 unduplicated empirical reports were generated by the search and examined for this review. This included 83 references on September 11, 29 on the 2004 Tsunami, and 53 on Hurricane Katrina.

CONCLUSIONS

A diversity of methods has been brought to bear in understanding children's reactions to disasters. While cross-sectional studies predominate, pre-event data for some investigations emerged from archival data and data from studies examining non-disaster topics. The nature and extent of the influence of risk and protective variables beyond disaster exposure are not fully understood due, in part, to limitations in the study designs used in the extant research. Advancing an understanding of the roles of exposure and various individual, family, and social factors depends upon the extent to which measures and assessment techniques are valid and reliable, as well as on data sources and data collection designs. Comprehensive assessments that extend beyond questionnaires and checklists to include interviews and cognitive and biological measures to elucidate the negative and positive effects of disasters on children also may improve the knowledge base.

Trusted information sources used during and after Superstorm Sandy: TV and radio were used more often than social media

Health and safety professionals and the public are interested in the best methods of providing timely information about disasters. The objective of this study was to examine information sources used for Superstorm Sandy with respect to the storm, evacuation routes, shelters, safety, and health issues. Respondents in central New Jersey and Jersey shore communities were differentially impacted by the storm. Jersey shore respondents had higher evacuation rates (47% vs. 13%), higher flood waters in homes, longer power outages (average 23 vs. 6 d), and longer periods without Internet (29 vs. 6 d). Electricity outages disrupted both sources and receivers of communication. Both groups obtained most of their information regarding safety from television, radio, friends, and Web/e-mail. Information sources on health varied by location, with central Jersey respondents using mainly TV and the Web, and Jersey shore respondents obtaining health information from the radio and TV (before the storm). For information on evacuation routes, Jersey shore respondents obtained information from many sources, while central Jersey respondents obtained it from TV. Information on mold was largely obtained from friends and the Web, since mold issues were dealt with several weeks after Sandy. The reliance on traditional sources of information (TV, radio, friends) found in this study suggests that the extreme power outages rendered Web, cell phones, and social media on cell phones less usable, and suggests the need for an integrated communication strategy with redundancies that takes into account prolonged power outages over large geographical areas.

Prevalence, incidence and determinants of PTSD and other mental disorders: design and methods of the PID-PTSD+3 study

Investigation of the prevalence, incidence, and determinants of post-traumatic stress disorders (PTSD) and other mental disorders associated with military deployment in international missions poses several methodological and procedural challenges. This paper describes the design and sampling strategies, instruments, and experimental procedures applied in a study programme aimed to examine military deployment-related mental health and disorders (prevalence and trajectories) and to identify vulnerability and risk factors (e.g. age, gender, type of mission, rank, and duration of deployment and a wide range of neurobiological, psychological, social, and behavioural factors). The study comprised two components. The first component, a cross-sectional study, included 1483 deployed and 889 non-deployed German soldiers (response rate, 93%) who served during the 2009 International Security Assistance Force (ISAF) mission. A standardized diagnostic instrument (Composite International Diagnostic Interview, CIDI) coupled with established questionnaires was administered to detect and diagnose PTSD and a broad spectrum of mental disorders and mental health problems. The second component, a prospective-longitudinal study, included 621 soldiers examined before (2011) and after return (2012) from the ISAF mission. In addition to the CIDI and questionnaires, several experimental behavioural tests and biological markers were implemented to probe for incident mental disorders, mental health problems and risk factors. Our methods are expected to provide greater precision than previous studies for estimating the risk for incident deployment-related and non-deployment-related disorders and their risk factors. We expect the findings to advance our understanding of a wide spectrum of adverse mental health outcomes beyond PTSD.

The importance of secondary trauma exposure for post-disaster mental disorder

BACKGROUND

Interventions to treat mental disorders after natural disasters are important both for humanitarian reasons and also for successful post-disaster physical reconstruction that depends on the psychological functioning of the affected population. A major difficulty in developing such interventions, however, is that large between-disaster variation exists in the prevalence of post-disaster mental disorders, making it difficult to estimate need for services in designing interventions without carrying out a post-disaster mental health needs assessment survey. One of the daunting methodological challenges in implementing such surveys is that secondary stressors unique to the disaster often need to be discovered to understand the magnitude, type, and population segments most affected by post-disaster mental disorders.

METHODS

This problem is examined in the current commentary by analyzing data from the WHO World Mental Health (WMH) Surveys. We analyze the extent to which people exposed to natural disasters throughout the world also experienced secondary stressors and the extent to which the mental disorders associated with disasters were more proximally due to these secondary stressors than to the disasters themselves. RESULTS. Lifetime exposure to natural disasters was found to be high across countries (4.4-7.5%). 10.7-11.4% of those exposed to natural disasters reported the occurrence of other related stressors (e.g. death of a loved one and destruction of property). A monotonic relationship was found between the number of additional stressors and the subsequent onset of mental disorders CONCLUSIONS. These results document the importance of secondary stressors in accounting for the effects of natural disasters on mental disorders. Implications for intervention planning are discussed.

Project VALOR: design and methods of a longitudinal registry of post-traumatic stress disorder (PTSD) in combat-exposed veterans in the Afghanistan and Iraqi military theaters of operations

Few studies have investigated the natural history of post-traumatic stress disorder (PTSD). Project VALOR (Veterans' After-discharge Longitudinal Registry) was designed as a longitudinal patient registry assessing the course of combat-related PTSD among 1600 male and female Veterans who served in Operation Enduring Freedom (OEF) in Afghanistan or Operation Iraqi Freedom (OIF). Aims of the study include investigating patterns and predictors of progression or remission of PTSD and treatment utilization. The study design was based on recommendations from the Agency for Healthcare Quality and Research for longitudinal disease registries and used a pre-specified theoretical model to select the measurement domains for data collection and interpretation of forthcoming results. The registry will include 1200 male and female Veterans with a recent diagnosis of PTSD in the Department of Veteran Affairs (VA) electronic medical record and a comparison group of 400 Veterans without a medical record-based PTSD diagnosis, to also allow for case-control analyses. Data are collected from administrative databases, electronic medical records, a self-administered questionnaire, and a semi-structured diagnostic telephone interview. Project VALOR is a unique and timely registry study that will evaluate the clinical course of PTSD, psychosocial correlates, and health outcomes in a carefully selected cohort of returning OEF/OIF Veterans.

A re-evaluation of the yield from national surveys of mental health

Having spent a considerable amount of time thinking about the uses of large-scale descriptive psychiatric epidemiological needs assessment surveys in our capacity as co-directors of the World Health Organization's World Mental Health Survey Initiative, we agree with many of the conclusions of Henderson and Andrews. Most importantly, we agree: that among the most important benefits of these surveys have been their political value in documenting high prevalence and high disabilitythat the time has come to expand the focus to study causes.
