Different types of exposure to the 2004 tsunami are associated with different levels of psychological distress and posttraumatic stress

Mental health burden following extreme weather events in South-east Asia: A systematic review and meta-analysis

Background

Exposure to extreme weatherly events potentially develops mental disorders among affected individuals.

Aim

To synthesize the burden of mental disorders following impact of extreme weather events in South-east Asian (SEA) countries.

Methods

Proposal was registered in PROSPERO register [CRD42023469788] and reported as per PRISMA-2020 guidelines. Studies reporting prevalence of mental health disorders following extreme weather events from SEA countries during 1990 and 2023 were searched on Embase, PubMed, and Scopus databases. Study quality was assessed using Appraisal tool for Cross-Sectional Studies. Overall pooled prevalence was computed using DerSimonian-Laird method for random-effects model and reported as 95% confidence intervals.

Results

On screening 12,046 records, we included 155 studies (2,04,474 participants) for analysis. Overall burden of mental disorders was 35.31% (95%CI: 30.42%-40.21%). In subgroup analysis, studies on cyclones, India, local residents, children and adolescents, rural settings, and community settings reported higher burden of mental disorders. Depression (28.58%; 95%CI: 24.05%-33.1%) and PTSD (29.36%; 95%CI: 26.26%-32.46%) had similar prevalence. Visiting tourists to SEA region experienced fear, fear of recurrence of tsunami, nightmares, and sense of helplessness. Mental health outcomes were relatively higher in studies conducted within 1 year of events. Heterogeneity and possibility of publication bias exists among the reported studies.

Conclusion

With the significant rise in episodes of extreme weather events in SEA region over the last three decades, mental disorders are documented in different proportions. We suggest prioritizing well-informed policies to formulate inclusive and resilient strategies on effectively identifying and treating mental health concerns among victims of extreme weather events.

Cognitive and Relational Processes Associated to Mental Health in Italian High School Students during COVID-19 and Russian-Ukrainian War Outbreaks

The negative impact of the COVID-19 pandemic on mental health has been widely demonstrated; however, few studies have investigated the psychological processes involved in this impact, including core beliefs violation, meaning-making disruption, interpersonal support, or one's relational functioning. This study explored the mental health of 215 Italian adolescents during the COVID-19 pandemic and the subsequent outbreak of the Russian-Ukrainian war. By administering a set of questionnaires, several cognitive and emotional variables were investigated, including core belief violation, meaning attribution to the pandemic and war, attachment, and emotion regulation, social media addiction, and relationships with significant others and teachers. We conducted some descriptive, mean difference, correlational, and predictive analyses that revealed a significant association between core belief violation caused by war and pandemic, ability to integrate war and pandemic within personal meaning universe, the relational support received, and mental health. The relationship with teachers during these challenging periods improved significantly according to the respondents' opinion, becoming both more authoritative and empathic. This study offers insights into what cognitive and relational processes are useful to intervene on to reduce the distress of adolescents who are facing significant moments of crisis due to events that challenge their cognitive and emotional balance.

The impact of the Russian-Ukrainian war on the mental health of Italian people after 2 years of the pandemic: risk and protective factors as moderators

Objective

This contribution aimed at investigating the moderating role of risk (e.g., the negative influence of COVID-19 on mental health) and protective (e.g., post-traumatic growth) factors on the relationship between the concern for war and stress and anxiety/depression levels among Italian people.

Methods

A questionnaire that included sociodemographic characteristics, the Perceived Stress Scale (PSS-4), the Patient Health Questionnaire (PHQ-4), the Brief Resilience Scale (BRS), the Post-Traumatic Growth Inventory (PTGI), and questions formulated ad hoc about concern for war was administered online. A sample of 755 participants (65.4% females, mean age = 32.39, SD = 12.64, range = 18-75) was recruited by convenience and snowball sampling. The researchers spread the link to the questionnaire to their acquaintances asking them to fill it out and to recruit other people.

Results

Results showed that concern for war significantly augmented the levels of stress and anxiety/depression in Italian people. Being a healthcare professional or having a chronic illness negatively moderated the effect of concern for war on stress and anxiety/depression. Instead, the negative influence of COVID-19 on mental health positively moderated the effect of concern for war on stress. Moreover, the overall positive changes after trauma and four of its five scales (i.e., Relating to Others, New Possibilities, Personal Strength, and Spiritual Change), negatively moderated the effect of concern for war on anxiety/depression.

Conclusions

In conclusion, concern about the Russian-Ukrainian war affects the mental health of the Italian population even if they are not directly involved in the conflict.

Trajectories of psychological distress among individuals exposed to the 9/11 World Trade Center disaster

BACKGROUND

Individuals present in lower Manhattan during the 9/11 World Trade Center (WTC) disaster suffered from significant physical and psychological trauma. Studies of longitudinal psychological distress among those exposed to trauma have been limited to relatively short durations of follow-up among smaller samples.

METHODS

The current study longitudinally assessed heterogeneity in trajectories of psychological distress among WTC Health Registry enrollees - a prospective cohort health study of responders, students, employees, passersby, and residents in the affected area (N = 30 839) - throughout a 15-year period following the WTC disaster. Rescue/recovery status and exposure to traumatic events of 9/11, as well as sociodemographic factors and health status, were assessed as risk factors for trajectories of psychological distress.

RESULTS

Five psychological distress trajectory groups were found: none-stable, low-stable, moderate-increasing, moderate-decreasing, and high-stable. Of the study sample, 78.2% were classified as belonging to the none-stable or low-stable groups. Female sex, being younger at the time of 9/11, lower education and income were associated with a higher probability of being in a greater distress trajectory group relative to the none-stable group. Greater exposure to traumatic events of 9/11 was associated with a higher probability of a greater distress trajectory, and community members (passerby, residents, and employees) were more likely to be in greater distress trajectory groups - especially in the moderate-increasing [odds ratios (OR) 2.31 (1.97-2.72)] and high-stable groups [OR 2.37 (1.81-3.09)] - compared to the none-stable group.

CONCLUSIONS

The current study illustrated the heterogeneity in psychological distress trajectories following the 9/11 WTC disaster, and identified potential avenues for intervention in future disasters.

Children or adolescents who lost someone close during the Southeast Asia tsunami 2004 - The life as young

INTRODUCTION

To lose a person close suddenly, during childhood or adolescence, can be devastating. Many children or adolescents experienced the 2004 Indonesian tsunami when they were between 10- and 15-years-old. This study, from Stockholm, Sweden, describes the long-term effects of loss, eight- or nine-years post disaster, in young adulthood.

METHOD

A mixed-method approach was used including statistical analyses (n = 210) and interpretative phenomenological analysis (IPA).

RESULTS

It was shown that there was a significant difference between bereaved (n = 34) and nonbereaved (n = 176) respondents concerning, psychological distress, posttraumatic stress symptoms, and self-rated health. Three themes were found by using the IPA approach (n = 9): Living in traumas, carrying heavy baggage, and living with change.

CONCLUSION

The respondents described personal feelings of grief that are not expressed in their outward appearance or behavior in their daily living. When meeting young adults that have lost someone close in childhood or adolescence, this is important to have in mind.

The Pandemic Is Not Occurring in a Vacuum: The Impact of COVID-19 and Other Disasters on Workforce Mental Health in Australia

OBJECTIVE

Prior to coronavirus disease (COVID-19), many Australians experienced extreme bushfires, droughts, and floods. A history of experiencing these events might be a risk factor for increased psychological distress during COVID-19. This study aimed to provide insight into the mental health of Australian workers during the initial COVID-19 outbreak, with an additional focus on whether previous disaster exposure and impact from that disaster is a risk factor for increased psychological distress.

METHODS

A snowball recruitment strategy was used. Participants (n = 596) completed an online survey, which included the Depression Anxiety Stress Scales-21, and questions related to mental health and disaster exposure.

RESULTS

Overall, 19.2%, 13.4%, and 16.8% of participants were experiencing moderate to extremely severe depression, anxiety, and stress symptoms, respectively. Multiple regression found that higher depression, anxiety, and stress symptoms were associated with a pre-existing mental health diagnosis; only higher stress symptoms were associated with having experienced a disaster, with impact, in addition to COVID-19.

CONCLUSIONS

People who have experienced impact from an additional disaster might need additional support to protect their mental health during COVID-19. A focus on the cumulative mental health impacts of multiple disasters and the implications for organizational communities where recovery work is undertaken, such as schools and workplaces, is needed.

Sex differences in post-traumatic stress disorder in cardiovascular patients after the Great East Japan Earthquake: a report from the CHART-2 Study

Aims

The temporal changes and sex differences in post-traumatic stress disorder (PTSD) after natural disasters remain unclear. Therefore, we examined the prevalence, prognostic impacts, and determinant factors of PTSD after the Great East Japan Earthquake (GEJE) of 11 March 2011 in cardiovascular (CV) patients registered in the Chronic Heart Failure Analysis and Registry in the Tohoku District (CHART)-2 Study (n = 10 219), with a special reference to sex.

Methods and results

By self-completion questionnaires of the Japanese-language version of the Impact of Event Scale-Revised (IES-R-J), the prevalence of PTSD, defined as IES-R-J score ≥25, was 14.8, 15.7, 7.4, and 7.5% in 2011, 2012, 2013, and 2014, respectively. The PTSD rate was higher in women than in men in all years (all P < 0.01). During a median 3.5-year follow-up period, the patients with PTSD in 2011 more frequently experienced a composite of all-cause death and hospitalization for acute myocardial infarction, stroke, and heart failure than those without PTSD [adjusted hazard ratio (aHR) 1.27, P < 0.01]. Importantly, the prognostic impacts of PTSD on all-cause death (aHR 2.10 vs. 0.87, P for interaction = 0.03) and CV death (aHR 3.43 vs. 0.90, P for interaction = 0.02) were significant in women but not in men. While insomnia medication was a prominent determinant factor of PTSD in both sexes during 2011-14, economic poverty was significantly associated with PTSD only in men.

Conclusion

After the GEJE, marked sex differences existed in the prevalence, prognostic impacts, and determinant factors of PTSD, suggesting the importance of sex-sepcific mental stress care in disaster medicine.

Well-Being and Functioning at Work Following Thefts and Robberies: A Comparative Study

Thefts and robberies may be traumatizing experiences for employees. The aim of this study is to explore to what extent experiencing robberies and/or thefts at work affect workers' mental health, coping-self-efficacy, social support seeking, workload and job satisfaction. Drawing on Conservation of Resources theory, this research contributes to our understanding of the psychological sequelae of robbery and theft for employees working in small businesses. The few studies on the effects of robberies and thefts in the past have predominantly focused on bank employees. A sample of Italian tobacconists and jewelers completed an anonymous self-report questionnaire examining the experience of robbery and/or theft, social support seeking (Coping Orientation to Problem Experienced scale, COPE-IV), psycho-somatic well-being (General Health Questionnaire, GHQ-12), job satisfaction (a single item). Victims of thefts and/or robberies reported their PTSD symptoms (Impact of Event- Revised 6, IES-R-6) and trauma-related coping self-efficacy (Coping Self-Efficacy scale, CSE-7), based on the last event (N = 319). Descriptive analyses, ANOVA, ANCOVA and multiple regressions analyses have been carried out. The results indicated that victims of thefts and robberies experienced greater workload, higher psycho-physical complaints and greater tendency to seek social support in comparison with their non-affected counterparts. They additionally experienced more post-traumatic symptomatology and perceived lower coping self-efficacy, when compared to those who experienced thefts “only.” Multiple regression analyses revealed that CSE was positively related to job satisfaction, although the presence of psycho-physical symptoms was the main predictor of job satisfaction among both non-affected and affected employees. PTSD was not an independent predictor of job satisfaction. In sum, robberies and/or thefts exposure undermines differently workers' well-being.

Children exposed to a natural disaster: psychological consequences eight years after 2004 tsunami

BACKGROUND

There is a need for studies that follow up children and adolescents for many years post disaster since earlier studies have shown that exposure during natural disasters constitutes a risk factor for poor psychological health.

AIMS

The main aim was to examine whether there was an association between severity of exposures during a natural disaster experienced in childhood or adolescence and posttraumatic stress symptoms, psychological distress, self-rated health, diagnosis of depression, anxiety or worry, thoughts about or attempted suicide, physical symptoms or daily functioning eight years later in young adulthood. A second aim was to compare psychological distress and self-rated health of exposed young adults with a matched population-based sample.

METHOD

Young adults, who experienced the 2004 tsunami as children between 10 and 15 years of age, responded to a questionnaire eight years post disaster. The results were compared to a matched population sample.

RESULTS

The results showed that the likelihood for negative psychological outcomes was higher for those who had been exposed to several types of exposures during this natural disaster.

CONCLUSIONS

The negative psychological impact on children and adolescents can still be present eight years post-disaster and seems to have association with the type of exposure; loss, physical presence and subjective experience. It is important for clinicians, who meet young adults seeking help, to be conscious about the impact as long as eight years post disaster and to be aware of possible clinical implications associated with severity of exposures.

An Analysis of Stories From Those Who Have Encountered Catastrophic Loss From Flood

Analyzing stories from those who have suffered catastrophic loss from flood may offer a means to better understand recovery of the survivors from their perspective. The purpose of this research was to examine the lived experience of those who faced catastrophic loss from flood. Stories were gathered from eight participants, who experienced catastrophic loss of home and possessions resultant of massive flooding. Following analysis, three "turning points" were identified within the story plot which included: Facing the devastation, Embracing the rebuilding, and Developing inner strength. Themes within the turning points were identified demonstrating transformational perspectives of self and world.

Posttraumatic growth and depreciation six years after the 2004 tsunami

Background: Posttraumatic growth (PTG) has been reported after various types of potentially traumatic events, as a part of the personal recovery process among survivors. Even negative changes in survivors' life view, known as posttraumatic depreciation (PTD), have been identified as an additional aspect in the personal recovery processes. Objective: To examine how the type of exposure experienced by survivors of a natural disaster, the 2004 Southeast Asia tsunami, influenced self-reported PTG and PTD six years later (T2). Additionally, the study examined the relations between psychological distress and posttraumatic stress symptoms (PTSS) 14 months after the disaster (T1), to PTG and PTD, respectively at T2. Finally, the study examined whether psychological distress and PTSS (T1) could have a mediating effect on PTG and PTD at T2. Method: The participants were 848 tsunami survivors living in Stockholm, Sweden who responded to a questionnaire at 14 months (T1) and six years (T2) after the tsunami. The material was analysed using linear regression and pathway analysis. PTG and PTD were measured on separate scales. Results: The type of exposure was significant related to both PTG and PTD six years later (T2). Those experiencing a combination of various types of exposure (including threat to life and bereavement) reported higher scores for both PTG and PTD. There were significant positive correlations between PTSS at T1 and PTG /PTD at T2, and somewhat lower correlations between psychological distress at T1 and PTG/PTD at T2. Both PTSS and psychological distress at T1 were significant mediating variables for both PTG and PTD at T2. Conclusions: Studying survivors' various types of exposure and subsequent changed view of life - both PTG and PTD - resulted in a broadened understanding of the complexity of reactions and the recovery process among survivors.

International Tourists' Reactions to a Natural Disaster: Experiences of the 2015 Earthquake in Nepal Among Israeli Travelers

There is a scarcity of research exploring the experiences of foreign travelers exposed to natural disasters while abroad. This qualitative study explored the experiences of the 2015 earthquake in Nepal among international travelers immediately following the earthquake. In-depth interviews were conducted with 21 Israeli backpackers who were traveling in Nepal at the time of the earthquake. Thematic analysis revealed 4 themes: emotional turmoil, quick recovery, springing into action, and connection to the army. Findings suggest that foreign travelers initially respond with emotional turmoil to the disaster. Then they actively search for ways to effectively cope with the situation by problem solving, creating a community of action and support, and searching their own history for similar circumstances that can provide a sense of competence or clear directions for coping. Implications and limitations of the study, as well as suggestions for future research are discussed.

Trauma or growth after a natural disaster? The mediating role of rumination processes

The aim of this study was to test a cognitive model of posttraumatic symptoms (PTS) and posttraumatic growth (PTG) after exposure to a natural disaster. It was hypothesized that although subjective severity of trauma would be related to the severity of PTS, this relation would be mediated by brooding and cognitive strategies related to the presence of repetitive negative content in thoughts. Furthermore, the relation between severity and PTG would be fully mediated by deliberate rumination (DR), cognitive strategies related to conscious efforts focused on handling the event. To evaluate the cognitive model, adults (N=351) who lost their homes as a result of the earthquake and tsunami that occurred in Chile on February 27, 2010, were selected. Structural equation modeling was used to analyze the data. The resulting model had adequate indices of goodness adjustment and showed that brooding completely mediated the relation between subjective severity and PTS, and DR completely mediated the relation between subjective severity, brooding, and PTG. These results highlight the role of both the content and process of rumination in mediating the association between subjective severity of trauma, PTS, and PTG. The implications of these results for a more comprehensive model of symptom severity that occurs after trauma are discussed.

Posttraumatic stress in survivors 1 month to 19 years after an airliner emergency landing

Posttraumatic stress (PTS) is common in survivors from life-threatening events. Little is known, however, about the course of PTS after life threat in the absence of collateral stressors (e.g., bereavement, social stigma, property loss) and there is a scarcity of studies about PTS in the long term. This study assessed the short- and long-term course of PTS, and the influence of gender, education and age on the level and course of PTS, in survivors from a non-fatal airliner emergency landing caused by engine failure at an altitude of 1 km. There were 129 persons on board. A survey including the Impact of Event Scale was distributed to 106 subjects after 1 month, 4 months, 14 months, and 25 months, and to 95 subjects after 19 years (response rates 64-83%). There were initially high levels of PTS. The majority of changes in PTS occurred from 1 to 4 months after the event. There were small changes from 4 to 25 months but further decrease in PTS thereafter. Female gender was associated with higher levels of PTS whereas gender was unrelated to the slope of the short- and long-term trajectories. Higher education was related to a quicker recovery although not to initial or long-term PTS. Age was not associated with PTS. The present findings suggest that a life-threatening experience without collateral stressors may produce high levels of acute posttraumatic stress, yet with a benign prognosis. The findings further implicate that gender is unrelated to trajectories of recovery in the context of highly similar exposure and few collateral stressors.

Trauma-induced insomnia: A novel model for trauma and sleep research

Traumatic events have been increasingly recognized as important precipitants of clinically significant insomnia. Trauma is an extreme form of stressful life event that generates a sustained neurobiological response triggering the onset and maintenance of insomnia. Trauma may disrupt the normal sleep-wake regulatory mechanism by sensitizing the central nervous system's arousal centers, leading to pronounced central and physiological hyperarousal. The central concept of hyperarousal has been linked to both the pathogenesis of insomnia and to the neurobiological changes in the aftermath of traumatic events, and may be a neurobiological commonality underlying trauma and insomnia. This paper presents evidence for trauma-induced insomnia and advances a model of it as an important nosological and neurobiological entity. Trauma-induced insomnia may occur in the absence of full-blown posttraumatic stress disorder (PTSD), and may also be a precursor of subsequent PTSD development. Converging lines of evidence from the neuroscience of insomnia with the neurobiology and psychophysiology of stress, fear, trauma and PTSD will be integrated to advance understanding of the condition. Preclinical and clinical stress and fear paradigms have informed the neurobiological pathways mediating the production of insomnia by trauma. Elucidating the underlying neurobiological substrates can establish novel biological markers to identify persons at risk for the condition, and help optimize treatment of the trauma-insomnia interface. Early identification and treatment of trauma-induced insomnia may prevent the development of PTSD, as well as other important sequelae such as depression, substance dependence, and other medical conditions.

Trauma signature analysis of the great East Japan disaster: guidance for psychological consequences

OBJECTIVES

On March 11, 2011, Japan experienced the largest earthquake in its history. The undersea earthquake launched a tsunami that inundated much of Japan's eastern coastline and damaged nuclear power plants, precipitating multiple reactor meltdowns. We examined open-source disaster situation reports, news accounts, and disaster-monitoring websites to gather event-specific data to conduct a trauma signature analysis of the event.

METHODS

The trauma signature analysis included a review of disaster situation reports; the construction of a hazard profile for the earthquake, tsunami, and radiation threats; enumeration of disaster stressors by disaster phase; identification of salient evidence-based psychological risk factors; summation of the trauma signature based on exposure to hazards, loss, and change; and review of the mental health and psychosocial support responses in relation to the analysis.

RESULTS

Exposure to this triple-hazard event resulted in extensive damage, significant loss of life, and massive population displacement. Many citizens were exposed to multiple hazards. The extremity of these exposures was partially mitigated by Japan's timely, expert-coordinated, and unified activation of an evidence-based mental health response.

CONCLUSIONS

The eastern Japan disaster was notable for its unique constellation of compounding exposures. Examination of the trauma signature of this event provided insights and guidance regarding optimal mental health and psychosocial responses. Japan orchestrated a model response that reinforced community resilience.

Polytraumatization in an adult national sample and its association with psychological distress and self-esteem

OBJECTIVE

The objective of this study was to examine the prevalence of self-reported experiences of potential childhood traumas and polytraumatization, and to find cut-off values for different kinds of potential traumatic events in a national representative sample of adults in Sweden. In addition, to analyse the association between polytraumatization and both psychological distress and global self-esteem.

METHOD

A web-based survey - containing SCL-25 and Rosenberg Self-Esteem Scale, and Linköping Difficult Life Events Scale - Adult - was sent out to a nationally reprative sample and 5062 people chose to participate in the study.

RESULTS

Results showed that almost everyone (97%) has experienced at least one potential traumatic event and that polytraumatization (the 10% of the participants with most reported traumas) was significantly (Z = 12.57, P < 0.001, r = 0.18) associated with psychological distress and global self-esteem. Gender differences were significant (Z = 8.44, P < 0.001, r = 0.12), in that men experience more noninterpersonal traumas but women report more symptoms. The effect sizes regarding the impact of potential trauma on self-esteem were largest for women with experience of polytraumatization in the age group 18-25 (r = 0.48). There was almost linear increase in psychological distress and linear decrease in self-esteem with increasing number of traumatic events experienced.

CONCLUSION

Experience of polytrauma can be considered an important factor to take into account in psychiatric settings as well.

Preliminary findings on lifetime trauma prevalence and PTSD symptoms among adolescents in Sarawak Malaysia

OBJECTIVE

The objective of this study is to determine the prevalence of lifetime exposure to traumatic events and its relation to PTSD symptoms.

METHODS

Participants were randomly selected from several schools located in the city of Kuching. There were 85 adolescents participating in this study, with ages ranging from 13 to 14 years old, of whom 31% (n=26) were males and 69% (n=59) females. The Child Posttraumatic Stress Index-Revised, The Harvard Trauma Questionnaire and a lifetime trauma checklist were used in this study.

RESULTS

Results showed that 77.6% of participants were exposed to at least one lifetime trauma. The most frequently reported traumas were road accident (20.1%), death of a family member (19.7%), and almost drowning (10%). There was more indirect trauma than direct trauma exposure. Males were more likely to be involved in traumatic events than females. Results showed that 7.1% (6) exhibited PTSD symptoms. There was no significant difference in the mean score of CPTS-RI between genders and among ethnic groups. Total exposure to traumatic events was significantly correlated with PTSD symptoms.

CONCLUSION

Findings suggest that number of lifetime traumatic events was quite high and multiple exposures to traumatic events were significantly related to PTSD symptoms.

Snapshot from Superstorm Sandy: American Red Cross mental health risk surveillance in lower New York State

STUDY OBJECTIVE

Disasters often cause psychological injury, as well as dramatic physical damage. Epidemiologic research has identified a set of disaster experiences and predisposing characteristics that place survivors at risk for post traumatic stress disorder (PTSD), depression, and anxiety. Rapid triage of at-risk survivors could have benefits for individual and population-level outcomes. We examine American Red Cross mental health risk surveillance data collected from October 29 to November 20, 2012, immediately after Hurricane Sandy in 8 lower New York State counties to evaluate the feasibility and utility of collecting these data.

METHODS

PsySTART, an evidence-based disaster mental health triage tool, was used to record survivor-reported risk factors after each survivor contact. Red Cross disaster mental health volunteers interfaced with survivors at disaster operation sites, including shelters, emergency aid stations, and mobile feeding and community outreach centers. Risk data were called into the operations center each day and reported by county.

RESULTS

PsySTART risk surveillance data for 18,823 disaster mental health contacts are presented for adults and children. A total of 17,979 risk factors were reported. Overall levels of risk per contact were statistically different (χ(2)(1, N=6,045)=248.1; P<.001) across the 8 counties. Survivors with high levels of risk were found in locations apart from the areas with the greatest physical damage.

CONCLUSION

Aggregated PsySTART data in Superstorm Sandy indicate substantial population-level impact suggestive of risk for disorders that may persist chronically without treatment. Mental health triage has the potential to improve care of individual disaster survivors, as well as inform disaster management, local health providers, and public health officials.

Peritraumatic distress but not dissociation predicts posttraumatic stress disorder in the elderly

BACKGROUND

Post-traumatic stress disorder (PTSD) is a severe anxiety disorder whose symptoms include re-experiencing, avoidance, and hyperarousal after a particularly intense event. In view of the aging of the population, increased clinical knowledge is required for better understanding of PTSD in the elderly. Extending previous research in this field in adults and children, the aim of our study was to assess the utility of peri-traumatic dissociation and distress as a predictor of PTSD in the elderly.

METHODS

A prospective longitudinal study was conducted in a consecutive cohort of subjects aged 65 years and over admitted to emergency departments after a physical assault or a road traffic accident. Peri-traumatic responses of distress and of dissociation were measured. One, 6, and 12 months after trauma exposure, PTSD symptoms and diagnosis were assessed using both a dimensional and a semistructured interview.

RESULTS

Thirty-nine male and female participants with an average age of 72.4 years were recruited. Mixed model regression analyses did not detect a significant effect of age, sex, nor time. Significant associations were detected between peri-traumatic distress and the self-report PTSD Checklist (p = 0.008), as well as the Clinician-administered PTSD scale (p = 0.03). No association was detected between peri-traumatic dissociation and PTSD.

CONCLUSIONS

Peri-traumatic distress predicts PTSD symptoms and diagnosis in the elderly, thereby suggesting its systematic evaluation at the emergency department would be a worthwhile thing to do.

Posttraumatic reactions to an earthquake: multidimensional scaling profile analysis of adolescent survivors

The current study examined the prototypical profiles of posttraumatic stress reactions among a sample of 282 adolescent survivors of the 2008 Wenchuan earthquake in China. Based on a dimensional perspective, the results of profile analysis via multidimensional scaling (PAMS) model revealed a two-dimensional solution corresponding to four profiles: intrusion, avoidance/arousal, partial avoidance, and hyperarousal. These profiles of posttraumatic stress symptoms equally manifested across gender. In addition, the Intrusion Profile was found to be associated with more elevated psychological distress symptoms. Results are discussed with respect to the typical posttraumatic stress symptoms following the earthquake.

Support, opinion of support and psychological health among survivors of a natural disaster

BACKGROUND

Although formal intervention after disasters is recommended, the evidence base for this is weak. Satisfaction with support after disasters is seldom investigated and the relation to psychological symptoms is unknown.

AIMS

To investigate whether dissatisfaction with social and formalized support are associated with post-disaster psychological symptoms.

METHODS

A total of 1,505 Swedish survivors of the 2004 Indian Ocean tsunami responded to a questionnaire 14 months after the disaster, including the General Health Questionnaire-12, the Impact of Events Scale - Revised, the Crisis Support Scale, and questions concerning the reception and appraisal of social and formalized support from health care, psychological services and insurance agencies. Disaster exposure and background factors were controlled for in the analyses.

RESULTS

Reception of formalized support, but not social support, was associated with both psychological distress and post-traumatic stress. Dissatisfaction with social but not formalized support, with the exception of support from insurance agencies, was associated with psychological distress.

CONCLUSIONS

Social support and formalized support should be differentiated in future studies in order to improve preventive intervention efforts after disasters. The reporting of dissatisfaction with social support merits special attention, since this may indicate increased risk for psychological symptoms.

Longitudinal course of physical and psychological symptoms after a natural disaster

BACKGROUND

After disaster, physical symptoms are common although seldom recognized due to lack of knowledge of the course of symptoms and relation to more studied psychological symptoms.

OBJECTIVE

This study aimed to investigate the change in the reporting of different physical symptoms after a disaster, including possible factors for change, and whether psychological symptoms predict physical symptoms reporting at a later point in time.

METHOD

A longitudinal study of citizens of Stockholm who survived the 2004 Indian Ocean tsunami. A total of 1,101 participants completed questionnaires on somatic symptoms, general distress, posttraumatic stress, exposure, and demographic details 14 months and 3 years after the disaster. Physical symptoms occurring daily or weekly during the last year were investigated in four symptom indices: neurological, cardiorespiratory, gastrointestinal, and musculoskeletal. We used generalized estimating equations (GEE) analysis to determine odds ratios for a change in symptoms, and pathway analysis to predict the influence of psychological symptoms on physical symptoms.

RESULTS

There was a general decrease of reporting in all physical symptom indices except the musculoskeletal symptom index. The change in the neurological symptom index showed the strongest association with exposure, and for women. General distress and posttraumatic stress at 14 months postdisaster predicted physical symptoms at 3 years.

CONCLUSION

Physical symptoms were predicted by psychological symptoms at an earlier time point, but in a considerable proportion of respondents, physical symptoms existed independently from psychological symptoms. Physicians should be observant on the possible connection of particular pseudoneurological symptoms with prior adversities.

Post- and peritraumatic stress in disaster survivors: an explorative study about the influence of individual and event characteristics across different types of disasters

BACKGROUND

Examination of existing research on posttraumatic adjustment after disasters suggests that survivors' posttraumatic stress levels might be better understood by investigating the influence of the characteristics of the event experienced on how people thought and felt, during the event as well as afterwards.

OBJECTIVE

To compare survivors' perceived post- and peritraumatic emotional and cognitive reactions across different types of disasters. Additionally, to investigate individual and event characteristics.

DESIGN

In a European multi-centre study, 102 survivors of different disasters terror attack, flood, fire and collapse of a building were interviewed about their responses during the event. Survivors' perceived posttraumatic stress levels were assessed with the Impact of Event Scale-Revised (IES-R). Peritraumatic emotional stress and risk perception were rated retrospectively. Influences of individual characteristics, such as socio-demographic data, and event characteristics, such as time and exposure factors, on post- and peritraumatic outcomes were analyzed.

RESULTS

Levels of reported post- and peritraumatic outcomes differed significantly between types of disasters. Type of disaster was a significant predictor of all three outcome variables but the factors gender, education, time since event, injuries and fatalities were only significant for certain outcomes.

CONCLUSION

Results support the hypothesis that there are differences in perceived post- and peritraumatic emotional and cognitive reactions after experiencing different types of disasters. However, it should be noted that these findings were not only explained by the type of disaster itself but also by individual and event characteristics. As the study followed an explorative approach, further research paths are discussed to better understand the relationships between variables.

Family structure and posttraumatic stress reactions: a longitudinal study using multilevel analyses

BACKGROUND

There is limited research on the relevance of family structures to the development and maintenance of posttraumatic stress following disasters. We longitudinally studied the effects of marital and parental statuses on posttraumatic stress reactions after the 2004 Southeast Asian tsunami and whether persons in the same households had more shared stress reactions than others.

METHOD

The study included a tourist population of 641 Norwegian adult citizens, many of them from families with children. We measured posttraumatic stress symptoms with the Impact of Event Scale-Revised at 6 months and 2 years post-disaster. Analyses included multilevel methods with mixed effects models.

RESULTS

Results showed that neither marital nor parental status was significantly related to posttraumatic stress. At both assessments, adults living in the same household reported levels of posttraumatic stress that were more similar to one another than adults who were not living together. Between households, disaster experiences were closely related to the variance in posttraumatic stress symptom levels at both assessments. Within households, however, disaster experiences were less related to the variance in symptom level at 2 years than at 6 months.

CONCLUSIONS

These results indicate that adult household members may influence one another's posttraumatic stress reactions as well as their interpretations of the disaster experiences over time. Our findings suggest that multilevel methods may provide important information about family processes after disasters.

Physical symptoms 14 months after a natural disaster in individuals with or without injury are associated with different types of exposure

OBJECTIVE

To investigate whether different types of exposure to the 2004 tsunami were associated with physical symptoms 14 months after the disaster and to study correlations between survivors' physical and psychological symptoms.

METHODS

Using a cross-sectional design, 1505 survivors from the 2004 Indian Ocean Tsunami, tourists from Stockholm, who had been present in the disaster areas, responded to a postal questionnaire. Eight groups based on type of exposure were created. Physical symptoms occurring on a daily or weekly basis over the past year were investigated in four indices: musculoskeletal, cardiorespiratory, neurological, and gastrointestinal. Mental health symptoms (General Health Questionnaire-12) and posttraumatic stress symptoms (Impact of Event Scale-Revised) were also investigated. Multiple logistic regression analyses were conducted with controls for background variables and exposure, with physical symptoms as outcome variables. The association between physical and psychological symptoms was studied with the Spearman Rank Order Correlation.

RESULTS

Different types of exposure during the disaster were associated with physical symptoms 14 months later for survivors both with and without severe physical injury. The single exposure of life threat, also in combination with other exposures, was associated with a higher risk for reporting of physical symptoms. Physical symptoms showed modest yet significant correlation with psychological symptoms.

CONCLUSION

It is important to pay attention to both physical and psychological symptoms among disaster survivors whether they have been injured or not. A relatively simple questionnaire about physical symptoms may be a good complement to the scales used to assess psychological problems after disaster.

Complicated grief associated with hurricane Katrina

BACKGROUND

Although losses are important consequences of disasters, few epidemiological studies of disasters have assessed complicated grief (CG) and none assessed CG associated with losses other than death of loved one.

METHODS

Data come from the baseline survey of the Hurricane Katrina Community Advisory Group, a representative sample of 3,088 residents of the areas directly affected by Hurricane Katrina. A brief screen for CG was included containing four items consistent with the proposed DSM-V criteria for a diagnosis of bereavement-related adjustment disorder.

RESULTS

Fifty-eight and half percent of respondents reported a significant hurricane-related loss: Most-severe losses were 29.0% tangible, 9.5% interpersonal, 8.1% intangible, 4.2% work/financial, and 3.7% death of loved one. Twenty-six point one percent respondents with significant loss had possible CG and 7.0% moderate-to-severe CG. Death of loved one was associated with the highest conditional probability of moderate-to-severe CG (18.5%, compared to 1.1-10.5% conditional probabilities for other losses), but accounted for only 16.5% of moderate-to-severe CG due to its comparatively low prevalence. Most moderate-to-severe CG was due to tangible (52.9%) or interpersonal (24.0%) losses. Significant predictors of CG were mostly unique to either bereavement (racial-ethnic minority status, social support) or other losses (prehurricane history of psychopathology, social competence.).

CONCLUSIONS

Nonbereavement losses accounted for the vast majority of hurricane-related possible CG despite risk of CG being much higher in response to bereavement than to other losses. This result argues for expansion of research on CG beyond bereavement and alerts clinicians to the need to address postdisaster grief associated with a wide range of losses.

Unlucky Victims or Lucky Survivors?

Subjective experiences of good or bad luck appear to depend upon downward or upward comparisons with close counterfactuals. People exposed to disasters have both options: They were at the wrong place at the wrong time, but their fate could in many cases have been worse; so in a sense, they are unlucky victims, but lucky survivors. Interviews with 85 Norwegian tourists 9–11 months after they had been exposed to the tsunami disaster in Southeast Asia showed good luck to be a pivotal theme in a majority of the narratives. Nobody claimed they had been unfortunate or unlucky. Moreover, downward counterfactual thoughts and downward comparisons with others occurred 10 times more often than upward counterfactuals and upward comparisons. In a follow-up 2 years later, 95% answered they had been lucky. A contextual analysis revealed several facets of luck, including its relation to gratitude, guilt, and supernatural beliefs.

Childhood life events and psychological symptoms in adult survivors of the 2004 tsunami

BACKGROUND

Negative life events in childhood have an adverse influence on adult psychological health, and increase vulnerability to subsequent potential traumas. It remains unclear whether this is also true in the case of disasters.

AIM

This study investigates whether the experience of negative life events in childhood and adolescence was associated with psychological symptoms in groups of Swedish survivors with different types of exposure to the tsunami.

METHODS

1505 survivors from Stockholm responded to a questionnaire on psychological distress, which was sent by post 14 months after the 2004 Indian Ocean tsunami. Psychological distress was measured by General Health Questionnaire-12 and suicidal ideation, and post-traumatic stress was measured by Impact of Event Scale-Revised. Life events prior to age 16 were collected and categorized under the indices accident, violence, loss and interpersonal events. Exposure to the tsunami was categorized in different types, and controlled for in the analyses.

RESULTS

With the adjustment for confounders, significant odds ratios were found for all indices on at least one outcome measure, despite the powerful effect of the tsunami. We could not discern any distinct difference in the distribution of the tendency to report the different outcomes depending on types of prior life events.

CONCLUSIONS

The implication of the study is that, for adult survivors of disaster, the reporting of adverse life events from childhood may influence future decisions regarding therapy.

Psychological distress and sick leave in Swedish survivors of the 2004 tsunami: a comparison with a population sample

Disaster studies of the effects of trauma exposure on subsequent psychological health have seldom used population comparisons. A total of 1463 tsunami survivors from Stockholm were categorized according to type of exposure, and compared on measures of General Health Questionnaire and sick leave, with a matched population-based sample of 12,045 individuals from the same region. Data from the survivor group were obtained through a postal questionnaire 14 months postdisaster. Data from the population sample were collected in the same year. In comparison to the population sample, levels of sick leave ranged from higher in multiply exposed groups to lower in the least exposed group. For psychological distress, levels in multiply and moderately exposed groups were higher, and in lower exposed groups comparable. The use of a population comparison resulted in a support of recent research showing a relative resiliency of survivors exposed during disaster to potential trauma of lesser severity.
