Exposure characteristics and peri-trauma emotional reactions during the 2004 tsunami in Southeast Asia--what predicts posttraumatic stress and depressive symptoms?

'I cannot see ahead': psychological distress, doomscrolling and dark future among adult survivors following Mw 7.7. and 7.6 earthquakes in Türkiye

BACKGROUND

The earthquakes, which occurred on 6 February 2023, affecting a total of eleven provinces in Türkiye, with magnitudes of 7.7 and 7.6, and killing around 50,000 people, caused the greatest loss of life compared to previous earthquakes in Türkiye. In this study, we analyse the psychological status of the adult individuals who experienced the earthquakes three months after the earthquakes in terms of different variables.

METHODS

In this research, an analytical cross-sectional study was conducted by applying face-to-face and online questionnaires to 402 adult individuals who had experienced the earthquake. The Depression, Anxiety and Stress Scale (DASS-21), the Dark Future Scale and Doomscrolling Scale were applied. The relationships between variables are discussed in this study using the predictive correlational model.

RESULTS

The results revealed that the participants had very high levels of future anxiety and moderate levels of doomscrolling after the earthquake. Although their psychological distress levels were relatively low, as the psychological distress levels of adult individuals who experienced the earthquake increased, their doomscrolling also increased. In addition, as individuals' future anxiety increases, their doomscrolling increases similarly. The mediation analysis reveals that the mediating role of future anxiety between psychological distress and doomscrolling is significant (p < .001).

CONCLUSION

Individuals are more exposed to negative news streams in negative life events that occur beyond their control and they need to search for information. Increased levels of depression, anxiety and stress lead to more exposure to this flow. In addition, future anxiety is also an important trigger of this behaviour. The effects of psychological distress on individuals who survived the earthquake are discussed in the context of the literature.

Do positive and negative emotional reactions during war predict subsequent symptomatology? A prospective experience sampling study

While peritraumatic negative emotions have been associated with subsequent posttraumatic stress and depression, the predictive role of real-time emotional reactions to specific stressors during prolonged stress exposure is still unclear, particularly that of positive emotions. The current study uses experience sampling methodology to examine individual general levels of negative and positive emotions, and emotional reactivity to specific stressors during war, as prospective predictors of posttraumatic stress and depression. Ninety-six civilians exposed to rocket fire during the 2014 Israel-Gaza war reported exposure to rocket warning sirens and levels of ten negative and six positive emotions twice a day for 30 days. Symptoms of posttraumatic stress and depression were then assessed two months post-war. Participants reported higher negative emotions and lower positive emotions during assessment windows with sirens. Over time, negative emotions decreased and positive emotions increased. Higher levels of overall negative emotions predicted posttraumatic stress symptoms and depression symptoms two months later. Levels of positive emotions, and negative and positive emotional reactivity to sirens, were not associated with subsequent symptomatology. Our results indicate the stronger role of overall negative emotions as predictors of symptomatology compared with momentary emotional reactivity, and the stronger predictive role of negative compared with positive emotions.

Validity, Reliability and Internal Consistency of Persian Versions of the Childhood Trauma Questionnaire, the Traumatic Exposure Severity Scale and the Peritraumatic Dissociative Experiences Questionnaire

The Childhood Trauma Questionnaire (CTQ), the Traumatic Exposure Severity Scale (TESS) and the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) are questionnaires widely used in studies of trauma and dissociation. This study aimed to examine the validity of the Persian versions of these questionnaires among a total of 230 individuals from the cities of Kermanshah and Sarpol-e Zahab that had experienced 2017 Iran earthquake. Results from a confirmatory factor analysis did not support the original five-factor solution for the TESS. Two principal component analyses resulted in a four-component solution for a revised version of the scale. PDEQ scores, TESS scores, and its sub-scales, were found to significantly correlate with a PTSD measure with their effect sizes ranging from medium to large according to Cohen's guidelines. Furthermore, significant correlations between two sub-scales of the CTQ and a dissociation measure were found with medium effect sizes. Consequently, reliability and validity measures obtained from the sample of this study were supportive of the use of the Persian versions of the TESS, the PDEQ, and the CTQ among Persian-speaking populations. Further research on psychological responses to earthquakes and other natural disasters can provide the opportunity for cross-cultural comparisons in terms of specific resilience factors and vulnerabilities following mass trauma.

The Association between General and Pathological Dissociation and Disaster-Related Psychopathology in Directly Exposed Survivors

Objective: Dissociation and trauma have a well-documented relationship, and dissociation is assumed to result from trauma exposure. If trauma generates dissociative psychopathology, it should be observed after exposure to disaster and be associated with disaster-related psychopathology. Few studies have focused specifically on dissociation as an outcome of disaster trauma. This study examined dissociation and its association with disaster-related psychopathology in survivors of five different disasters. Methods: In the first 6 postdisaster months, directly exposed survivors (N = 216) of mass shootings, floods, or a firestorm completed structured diagnostic interviews providing lifetime predisaster and postdisaster prevalent/incident psychiatric diagnoses and the Dissociative Experiences Scale (DES) 1-3 years after baseline. Results: DES scores were very low; only 1% met the DES Taxon signifying pathological dissociation. In multivariate models including predisaster lifetime major depression, lifetime panic disorder, lifetime generalized anxiety disorder, and lifetime alcohol use disorder; disaster-related PTSD; and number of incident somatoform symptoms as independent covariates, predisaster lifetime major depression and alcohol use disorder were independently associated with both general (DES score) and pathological (DES Taxon) dissociation, and postdisaster incident somatization symptoms were also associated with general dissociation, but postdisaster psychopathology including disaster-related PTSD was not associated with general or pathological dissociation. Conclusions: Neither general nor pathological dissociation was independently associated with disaster-related PTSD or other incident psychopathology. The only psychiatric disorders associated with dissociation were present before the disasters. Coupled with the low dissociation rates, these findings indicate that dissociation does not appear to be a mental health outcome of disaster trauma.

Dissociation and disasters: A systematic review

BACKGROUND

Dissociation, which is defined as the failure to associate consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior into an integrated whole, has long been assumed to be generated by trauma. If dissociation is a product of trauma exposure, then dissociation would be a major mental health outcome observed in studies of disaster survivors. Although some studies have examined dissociation in disasters, no systematic literature reviews have been conducted to date on the topic.

AIM

To systematically evaluate the literature on the association between disaster and dissociation to determine the prevalence and incidence of dissociation after exposure to disaster and further examine their relationship.

METHODS

EMBASE, Medline, and PsychINFO were searched from inception to January 1, 2019 to identify studies examining dissociative disorders or symptoms related to a disaster in adult or child disaster survivors and disaster responders. Studies of military conflicts and war, articles not in English, and those with samples of 30 or more participants were excluded. Search terms used were “disaster*” and dissociation (“dissociat*,” “multiple personality,” “fugue,” “psychogenic amnesia,” “derealization,” and “depersonalization”). Reference lists of identified articles were scrutinized to identify studies for additional articles.

RESULTS

The final number of articles in the review was 53, including 36 articles with samples of adults aged 18 and above, 5 of children/adolescents under age 18, and 12 of disaster workers. Included articles studied several types of disasters that occurred between 1989 and 2017, more than one-third (38%) from the United States. Only two studies had a primary aim to investigate dissociation in relation to disaster and none reported data on dissociative disorders. All of the studies used self-report symptom scales; none used structured interviews providing full diagnostic assessment of dissociative disorders or other psychopathology. Several studies mixed exposed and unexposed samples or did not differentiate outcomes between exposure groups. Studies examining associations between dissociation and disaster exposure have been inconclusive. The majority (75%) of the studies compared dissociation with posttraumatic stress, with inconsistent findings. Dissociation was found to be associated with a wide range of other psychiatric disorders, symptoms, and negative emotional, cognitive, and functional states.

CONCLUSION

The studies reviewed had serious methodological limitations including problems with measurement of psychopathology, sampling, and generation of unwarranted conclusions, precluding conclusions that dissociation is an established outcome of disaster.

A study of dissociation in survivors of 5 disasters

This study examined dissociation as an outcome to disaster in dissociative data collected from 423 highly-exposed survivors of 5 different disasters using consistent methodology. Ten items selected for conceptual relevance to disaster experience were administered from the Dissociative Disorders Interview Schedule, a structured interview for lifetime dissociative disorders. Structured psychiatric interviews provided data on incident somatization symptoms, disaster-related PTSD, and lifetime predisaster psychopathology. The Temperament and Character Inventory assessed personality. Observed levels of dissociation were low and not usually postdisaster. Dissociation level was associated with female sex, number of incident somatization symptoms, personality (underdeveloped executive functioning), PTSD, and predisaster psychopathology in bivariate analyses. In multiple linear regression models, dissociation was associated with the low number of incident somatoform symptoms observed independent of the effects of PTSD, hyperarousal specifically (but not intrusion or avoidance/numbing), personality, predisaster psychopathology, and demographic variables which were not independently associated with dissociation. The low levels of dissociation found in this study and the lack of association between dissociation and indicators of psychopathology point to a largely nonpathological nature of the dissociative phenomena measured. These findings do not indicate the development of dissociative psychopathology as a prevalent mental health outcome of disasters.

Methodology of "14-7" Program: A Longitudinal Follow-Up Study of the Pediatric Population and Their Families Exposed to the Terrorist Attack of Nice on July 14th, 2016

Introduction: After a traumatic event, children and adolescents may present several clinical consequences, the most common being Post-Traumatic Stress Disorder (PTSD). Most children and adolescents with PTSD have comorbid disorders, such Attention Deficit Hyperactivity Disorder, depression, attachment and anxiety disorders, sleep disturbances and behavior problems. However, epidemiological studies on the development of PTSD and other psychiatric disorders in children and adolescents as a consequence of a terrorist attack and mass murder are lacking. Long-term follow-up of exposed children and adolescents will help identify risk and protective factors of developing psychiatric and psychological conditions after exposure to traumatic events or situations. The main objective of this article is to present the methodology of "14-7" program. The aim of "14-7" program is to characterize the risk and protective psychosocial factors affecting the clinical evolution of a pediatric population sample, exposed to the terrorist attack of July 14^th, 2016 in Nice. Method and Analysis: "14-7" program is a multicentre longitudinal cohort study. Major inclusion criteria are children and adolescents exposed to the terrorist attack and aged under 18 years on July 14^th, 2016. These children and adolescents will be compared to a non-exposed to the "14-7" terrorist attack group, matched on age and gender. Participants will be assessed at baseline (T1), 2 years (T2) and 5 years (T3) after the initial assessment (T1), and every 5 years until they are 25 years old. Multiple domains are assessed: 1) mental health disorders, 2) intensity of PTSD symptoms, 3) intensity of comorbid symptoms, 4) quality of the parent-child relationship, 5) intelligence quotient, 6) parental symptoms. We will also establish a biological collection of saliva samples, magnetic resonance imaging (MRI) and actigraphy data collection. Main analyses comprise analyses of variance and regression analyses of predictors of clinical evolution over time. Ethics and Dissemination: The National Ethics Committee "NORD OUEST III" approved the "14-7" Program protocol (number 2017-A02212-51). All patients and their caregivers signed informed consent on enrolment in the "14-7" Program. Inclusions started on November 21^st, 2017. Three hundred thirty-five individuals have been included (191 children and adolescents, 144 parents). Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT03356028.

Risk factors of post-traumatic stress among survivors of the 2017 Iran earthquake: The importance of peritraumatic dissociation

The aim of this study was to explore the roles of pre-earthquake characteristics (age, gender, years of education, history of childhood and recent trauma and trait dissociation), during-the-earthquake state (peritraumatic dissociation) and post-earthquake difficulties (severity of exposure to earthquake) in post-traumatic stress among survivors of the 2017 Iran earthquake. A total number of 127 individuals in Kermanshah and 103 individuals in Sarpol-e Zahab completed and returned a 105-item questionnaire. Among these, 32 (25.2%) participants in the Kermanshah sample and 80 (77.7%) participants in the Sarpol-e Zahab sample scored equal to, or more than, the cut-off score of 33 on the Impact of Event Scale - Revised and, thus, were considered as having high likelihood of having PTSD. A three-model hierarchical linear regression analysis showed that pre-earthquake characteristics, during-the-earthquake state and post-earthquake difficulties each explained a unique variance of 11.3%, 34.4% and 14.7%, respectively, and together explained a total variance of 60.4% in post-traumatic stress. Earthquake victims who report higher degrees of peritraumatic dissociation during and immediately after the earthquake are more vulnerable to develop PTSD and should be prioritized in terms of receiving psychological interventions.

A longitudinal examination of peritraumatic emotional responses and their association with posttraumatic stress disorder and major depressive disorder among veterans

Research has revealed a significant association between several peritraumatic emotional responses and posttraumatic stress disorder (PTSD). Preliminary research has also linked peritraumatic emotional responses with a diagnosis of major depressive disorder (MDD). The majority of this research has been cross-sectional, thereby making it difficult to determine the extent to which the various peritraumatic emotional responses may increase risk for, or serve as a premorbid marker of, PTSD and MDD. This study examined the longitudinal role of peritraumatic emotional responses on the subsequent development of PTSD and MDD in a sample of US military veterans. Whereas a number of peritraumatic emotional responses were concurrently associated with PTSD, only peritraumatic numbness maintained the association with this diagnosis longitudinally. For MDD, peritraumatic numbness was the only emotional response related to the diagnosis both concurrently and longitudinally. Study findings are a preliminary proof of concept that peritraumatic numbness may serve as a premorbid marker for the development of PTSD and MDD following a traumatic event. Implications of these findings for the diagnosis, assessment, and treatment of both PTSD and MDD are discussed.

Prevalence and Risk Factors for Post-Traumatic Stress Reaction Among Resident Survivors of the Tsunami That Followed the Great East Japan Earthquake, March 11, 2011

Objective

The Great East Japan Earthquake triggered a massive tsunami that devastated the coasts of northern Japan on March 11, 2011. Despite the large number of “resident survivors,” who have continued to reside on the upper floors of damaged houses, few studies have examined the mental health of these residents. We explored the prevalence and risk factors of post-traumatic stress reaction (PTSR) among resident survivors.

Methods

A cross-sectional household screening for health support needs was conducted among resident survivors in Higashi-Matsushima city, Miyagi, 2 to 4 months after the tsunami. Questions assessing PTSR were included in the screening interviews.

Results

Of 5103 resident survivors, 5.7% experienced PTSR. PTSR risk factors, identified via regression analysis, differed according to the height of house flooding. When house flooding remained below the ground floor, PTSR was significantly associated with being female and regular psychotropic medication intake. These 2 factors in addition to being middle-aged or elderly and living alone were also risk factors when flood levels were above the ground floor.

Conclusions

Following the tsunami, PTSR was found in a considerable number of resident survivors. Attention and support for people who use psychiatric medication, their families, and people living alone are suggested as possible directions for public health strategies.

Prevalence and risk factors for depressive reaction among resident survivors after the tsunami following the Great East Japan Earthquake, March 11, 2011

Objectives

The Great East Japan Earthquake caused a gigantic tsunami which devastated coastal areas of northern Japan on 11 March 2011. Despite the large number of ‘resident survivors’ who continued to reside in their damaged houses on the second or upper floors, research on the mental health of these individuals has been limited. This study explored the prevalence of depressive reaction and risk factors for depressive reaction among these resident survivors.

Methods

A cross-sectional household health support needs screening was conducted for resident survivors in Higashi-Matsushima city, Miyagi prefecture, two to four months after the tsunami. The health interview that was conducted including mental status, assessed by the Patient Health Questionnaire-2 (PHQ-2).

Results

Of 5,454 respondents, 8.1% had depressive reaction. After adjustment by the number of weeks from the tsunami and the mortality rate at each respondent's place of residence, depressive reaction was significantly associated with house flooding below or above the ground floor (odds ratios of 1.92, 2.36, respectively), the unavailability of gas supply (odds ratio, 1.67), being female (odds ratio, 1.47), middle aged or elderly (odds ratios of 2.41, 2.42, respectively), regular intake of psychotropic medicine(s) since before the tsunami (odds ratio, 2.53) and the presence of one to five or more than six cohabiters (odds ratios of 0.61, 0.52, respectively).

Conclusions

The results suggest a considerable psychological burden (depressive reaction) following the tsunami among resident survivors. Special supports for families with psychiatric problems need to be considered among resident survivors. Restoration of lifeline utilities and the strengthening of social ties of persons living alone may help prevent depressive reaction among resident survivors after a tsunami.

Impact on life after a major bus crash--a qualitative study of survivors' experiences

BACKGROUND

Crashes occur regularly throughout the world and can result in multiple fatalities and many injuries. Research into how survivors experience a crash is very limited.

AIM

To describe and analyse the nonphysical consequences of a multifatality bus crash in Sweden and the subsequent effect on the surviving passengers' lives.

METHOD

The participants were all (n = 56) of the survivors of a major bus crash. The passengers were interviewed approximately one month after the bus crash. The interviews were analysed using a qualitative content analysis.

RESULTS

Prior to the arrival of rescue personnel at the crash site, helpfulness emerged among the passengers. Further, the crash generated an impact on the surviving passengers' lives from a short-term perspective. The passengers displayed a diverse need for crisis support; informal support from family and friends was essential for the early healing process. Sleep difficulties and a change in travel routines were the most common consequences. Lastly, passengers sought closure in order to move on with their lives.

CONCLUSION

The passengers' reactions to and behaviour following a crash offer an insight into the, relatively unexplored, interaction between people experiencing a major road traffic crash. It is necessary to have a flexible crisis support system, and the vital role of family support ought to be upgraded.

Factors associated with posttraumatic stress disorder and depression in war-survivors displaced in Croatia

Aim

To examine the role of perceived stressfulness of trauma exposure and economic, social, occupational, educational, and familial adaptation after trauma in posttraumatic stress disorder (PTSD) and depression in displaced war survivors.

Methods

A cross-sectional survey was conducted between March 2000 and July 2002 with a sample of 173 internally displaced persons or refugees and 167 matched controls in Croatia. Clinical measures included Structured Clinical Interview for DSM-IV and Clinician-Administered PTSD Scale.

Results

Displaced war survivors reported the exposure to a mean ± standard deviation of 13.1 ± 8.3 war stressors, including combat, torture, serious injury, death of close persons, and loss of property. Compared to controls, they reported higher rates of marked to severe impact of war on family (16.2% vs 51.6%), social (7.2% vs 43.5%), economic (12.6% vs 55.4%), occupational (1.8% vs 15.9%), and educational (2.4% vs 8.8%) adaptation. In two logistic regression analyses, the strongest predictor of PTSD and depression was high level of perceived distress during trauma exposure. PTSD but not depression was associated with economic, social, occupational, educational, and familial adaptation after trauma.

Conclusion

Displaced survivors who experienced multiple war events perceived greater negative impact of war on their life domains compared to individuals who lived in a war setting but had no trauma exposure. The most important determinant of psychological outcomes was perceived stressfulness of war stressors. Although post-trauma adaptation in different life spheres had an impact, its effect was not robust and consistent across disorders. These findings suggest that it would be effective to use a trauma-focused approach in rehabilitation of war survivors.
