Posttraumatic stress disorder symptom trajectories in Hurricane Katrina affected youth

Experiences of adolescents affected by earthquakes: A qualitative study

PURPOSE

The aim of the study is to explore the experiences of adolescents affected by the earthquake.

DESIGN AND METHODS

This study was carried out in a descriptive phenomenological design, which is a qualitative research method. This research was conducted as a qualitative investigation utilizing a phenomenological approach to explore the experiences of 12 adolescents through the purposeful snowball sampling method. The interviews were conducted with adolescents who affected by the Kahramanmaraş earthquakes in a city located in the west of the country, between March 18, 2023 and June 30, 2023. Semistructured interviews were employed, and the data underwent inductive content analysis. COREQ reporting guidelines were used.

RESULTS

The participants in this study vividly recounted experiencing intense fear and panic during the earthquake. Subsequent challenges emerged from the lack of coordination in aid efforts, struggles to secure shelter and necessities, and the profound loss of relatives. These adversities posed considerable physical and psychological challenges. Notably, the adolescents' ability to reflect on their past lives and reshape their perspectives proved instrumental in facilitating their adaptation to a new life. However, witnessing the demise of loved ones, grappling with the fear of death and loss, and incessantly discussing the earthquake hindered their adjustment.

PRACTICE IMPLICATIONS

We found that adolescents experienced the quakes in three phases: in the moment, postquake, and adaptation to new life. The first theme underscores the limitations of current effectiveness of quake training. This finding has important implications for policy to better prepare the adolescent population for quake disasters. The second theme reveals that the communication and coordination problems experienced after the earthquake enable the weaknesses of the system to be noticed and political steps should be taken in this direction. The third theme focuses on the factors that increase or decrease the psychosocial adaptation of adolescents who have experienced this traumatic experience to the new life. This provides important clues to improve and support adolescent health.

Scoping review on trauma and recovery in youth after natural disasters: what Europe can learn from natural disasters around the world

In the last decade, Europe has seen a rise in natural disasters. Due to climate change, an increase of such events is predicted for the future. While natural disasters have been a rare phenomenon in Europe so far, other regions of the world, such as Central and North America or Southeast Asia, have regularly been affected by Hurricanes and Tsunamis. The aim of the current study is to synthesize the literature on child development in immediate stress, prolonged reactions, trauma, and recovery after natural disasters with a special focus on trajectories of (mal-)adaptation. In a literature search using PubMed, Psychinfo and EBSCOhost, 15 studies reporting about 11 independent samples, including 11,519 participants aged 3-18 years, were identified. All studies identified resilience, recovery, and chronic trajectories. There was also evidence for delayed or relapsing trajectories. The proportions of participants within each trajectory varied across studies, but the more favorable trajectories such as resilient or recovering trajectory were the most prevalent. The results suggested a more dynamic development within the first 12 months post-disaster. Female gender, a higher trauma exposure, more life events, less social support, and negative coping emerged as risk factors. Based on the results, a stepped care approach seems useful for the treatment of victims of natural disasters. This may support victims in their recovery and strengthen their resilience. As mental health responses to disasters vary, a coordinated screening process is necessary, to plan interventions and to detect delayed or chronic trauma responses and initiate effective interventions.

Resilience and Disaster: Flexible Adaptation in the Face of Uncertain Threat

Disasters cause sweeping damage, hardship, and loss of life. In this article, we first consider the dominant psychological approach to disasters and its narrow focus on psychopathology (e.g., posttraumatic stress disorder). We then review research on a broader approach that has identified heterogeneous, highly replicable trajectories of outcome, the most common being stable mental health or resilience. We review trajectory research for different types of disasters, including the COVID-19 pandemic. Next, we consider correlates of the resilience trajectory and note their paradoxically limited ability to predict future resilient outcomes. Research using machine learning algorithms improved prediction but has not yet illuminated the mechanism behind resilient adaptation. To that end, we propose a more direct psychological explanation for resilience based on research on the motivational and mechanistic components of regulatory flexibility. Finally, we consider how future research might leverage new computational approaches to better capture regulatory flexibility in real time.

Individual and Social Risk and Protective Factors as Predictors of Trajectories of Post-traumatic Stress Symptoms in Adolescents

The present study elucidates heterogeneity in post-traumatic stress symptoms (PTSS) across adolescence in a sample of youth who have experienced myriad types and combinations of potentially traumatic events (PTEs), including substantiated physical abuse, sexual abuse, neglect and/or at least one other self-reported PTE. A machine learning technique was used to assess a multivariate set of variables (e.g., PTEs, individual risk and protective factors, social risk and protective factors, and racial and ethnic minority status) as predictors of PTSS trajectory group membership. The sample included 498 maltreated (n = 275) and comparison (n = 223) 14-19-year-old female adolescents (M = 15.27, SD = 1.06 at Time 1) assessed annually until age 19. 45.7% of participants were White, 45.3% Black, 0.4% Native American, 0.8% Hispanic, and 7.7% other. Growth mixture modeling identified three distinct trajectories of PTSS: (1) recovery (56%); (2) moderate, chronic (25%); and (3) high, chronic (19%). An elastic net model was used to test predictors of membership in the recovery versus the high, chronic PTSS trajectory groups. Results demonstrated that the recovery trajectory was characterized by the absence of sexual abuse, physical abuse, and other traumas, higher self-esteem, less affective dysregulation, less risky peers, lower levels of parent depression, and being of racial/ethnic minority status. Findings help to characterize individual variation in trajectories of PTSS following PTEs by underscoring the unique trauma responses of racial and ethnic minority youth and offering possible targets of interventions to promote recovery from PTSS.

Psychosocial resources underlying disaster survivors' posttraumatic stress symptom trajectories: insight from in-depth interviews with mothers who survived Hurricane Katrina

Background: Weather-related disasters, including hurricanes, are becoming more frequent and severe due to climate change. Vulnerable populations, such as people with low income and racial and ethnic minorities, are particularly prone to increased levels of physical harm and psychiatric adversity from weather-related events.Objectives: We aimed to explore psychosocial resources and coping of survivors with three different posttraumatic stress symptom (PTSS) trajectories (High-Decreasing, Moderate-Decreasing, and High-Stable), after Hurricane Katrina across two different time points: F1 (1-year post-disaster) and F3 (12 years post-disaster).Method: Participants in this multi-method study were part of a larger cohort of the Resilience in Survivors of Katrina (RISK) project. Transcripts of interviews completed at the two time points were analysed using two qualitative methods, combining thematic analysis and narrative analysis, and providing both breadth of perspectives with the depth of specific case studies.Results: Sixteen survivors completed interviews at both F1 and F3. From our in-depth analysis of the data, we derived five inductive themes: 'Hope,' 'Adaptive vs maladaptive avoidance,' 'Emotional delay,' 'Acceptance, Finding Meaning and Being in the Moment,' and 'Coping strategies.' Survivors with High-Decreasing and Moderate-Decreasing PTSS trajectories experienced hope for future, accepted the hurricane and its results, and found efficient ways to cope with their situation. Survivors with High-Stable PTSS trajectories tended to express a lack of hope for future and struggled to be mindful and accept the hurricane and its harm. Unlike survivors with High-Decreasing and Moderate-Decreasing PTSS trajectories, survivors with High-Stable PTSS trajectories also reported less social and family support and faced more discrimination and racism.Conclusion: There are factors beyond individual-level psychosocial resources that may shape post-disaster resilience. When supporting survivors after a weather-related disaster, it is essential to provide ongoing psychological, financial, and physical assistance to bolster these resources.

Climate change impacts on the mental health and wellbeing of young people: A scoping review of risk and protective factors

BACKGROUND/RATIONALE

The impact of climate change on the mental health of young people is poorly understood. Emerging evidence suggests that exposure to climate change exerts a disproportionate mental health burden on young people. An understanding of the risk factors (RFs) and protective factors (PFs) that affect the likelihood of mental health impacts arising from exposure to climate change is required to support youth wellbeing.

AIMS/OBJECTIVES

This review scopes the current research on what and how RFs and PFs are related to the mental health impacts of both direct and indirect exposure to climate change for young people. RFs and PFs were reviewed through the lens of ecological system theory.

METHODS

We conducted systematic searches in four databases: PubMed, PsycInfo, Web of Science, and Scopus. Grey literature searches were conducted in ProQuest Dissertations, GreyLit.org, OpenGrey, and relevant organisations' websites. We included 92 empirical studies focused on the RFs and PFs of the mental wellbeing under the impact of climate change of young people (0-24). We extracted data on study characteristics, type of climate change event, mental health outcomes, RFs and PFs, and associated ecological system level.

RESULTS

The current evidence base focuses predominantly on young people's experience of PTSD (k = 59), depression (k = 26), or anxiety (k = 17) mainly following exposure to singular climate change-related natural disaster events. Only four studies explored the impacts of climate change in general. Majority of the studies investigated RFs and PFs at the individual level and at the micro-system level.

CONCLUSIONS

Several RFs and PFs were identified, such as coping strategies, family factors (e.g. parenting style), social support, community connection, and cultural identity. Positioning the mental health impacts of singular events within the broader context of ongoing and escalating climate change impacts will better inform the development of interventions that seek to build resilience among young people.

Prevalence of Posttraumatic Stress Disorder Following the Earthquake in Iran and Pakistan: A Systematic Review and Meta-Analysis

Posttraumatic stress disorder (PTSD) is a common mental disorder following traumatic events. The present study was conducted to understand the prevalence of PTSD after the earthquake in Iran and Pakistan. The review includes all articles published from inception to March 2019. The pooled prevalence for overall PTSD was 55.6% (95% CI: 49.9-61.3). It was 60.2% (95% CI: 54.1-66.3) and 49.2% (95% CI: 39.4-59) for Iranian and Pakistani survivors, respectively. Women experienced higher incidence of PTSD than men. The variation of PTSD based on the clinical interview was lower than the self-report approach. The interval time between the earthquakes and the assessment showed that the prevalence of PTSD decreased over time. The prevalence of PTSD in Iran and Pakistan was higher than the global average, and the rate of the disorder in Iran was higher than in Pakistan. Sex, method of assessment, and time lag between the occurrence of disaster and assessment of PTSD affect the prevalence.

Latent Patterns of Posttraumatic Stress Symptoms, Depression, and Posttraumatic Growth Among Adolescents During the COVID-19 Pandemic

Researchhas shown that posttraumatic reactions can co-occur in trauma-exposed individuals. Many studies have assessed the co-occurring patterns of two types of reactions, but few have assessed the patterns of multiple reactions. To build on existing knowledge, the present study examined co-occurring patterns of posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, and posttraumatic growth (PTG) among adolescents during the COVID-19 pandemic. Participants (N = 683) were adolescents selected from an area in China severely affected by COVID-19 who completed the PTSD Checklist, a measure of depression, a PTG inventory, and a cognitive emotional regulation questionnaire. Latent profile analysis and multinomial logistic regression were used for the data analyses. The results showed three heterogeneous patterns characterized by growth (n = 248, 36.3%), distress (n = 101, 14.8%), and struggle (n = 334, 48.9%). Positive refocusing and reappraisal were associated with membership in the growth group compared with distress group, OR = 0.83, 95% CI [0.75, 0.93] and OR = 0.78, 95% CI [0.68, 0.90], whereas rumination, catastrophizing, and "putting into perspective" were associated with membership in the distress group compared with growth group, ORs = 1.15-1.44. These findings suggest that posttraumatic reactions show heterogeneous characteristics: struggle, rather than growth or distress, is common among adolescents during COVID-19; and distinct cognitive emotional regulation strategies have distinguishing roles in the three patterns of posttraumatic reactions.

Genome-wide Signatures of Early-Life Stress: Influence of Sex

Both history of early-life stress (ELS) and female sex are associated with increased risk for depression. The complexity of how ELS interacts with brain development and sex to impart risk for multifaceted neuropsychiatric disorders is also unlikely to be understood by examining changes in single genes. Here, we review an emerging literature on genome-wide transcriptional and epigenetic signatures of ELS and the potential moderating influence of sex. We discuss evidence both that there are latent sex differences revealed by ELS and that ELS itself produces latent transcriptomic changes revealed by adult stress. In instances where there are broad similarities in global signatures of ELS among females and males, genes that contribute to these patterns are largely distinct based on sex. As this area of investigation grows, an effort should be made to better understand the sex-specific impact of ELS within the human brain, specific contributions of chromosomal versus hormonal sex, how ELS alters the time course of normal transcriptional development, and the cell-type specificity of transcriptomic and epigenomic changes in the brain. A better understanding of how ELS interacts with sex to alter transcriptomic and epigenomic signatures in the brain will inform individualized therapeutic strategies to prevent or ameliorate depression and other psychiatric disorders in this vulnerable population.

Sex-differential PTSD symptom trajectories across one year following suspected serious injury

BACKGROUND

Recent years have shown an increased application of prospective trajectory-oriented approaches to posttraumatic stress disorder (PTSD). Although women are generally considered at increased PTSD risk, sex and gender differences in PTSD symptom trajectories have not yet been extensively studied.

OBJECTIVE

To perform an in-depth investigation of differences in PTSD symptom trajectories across one-year post-trauma between men and women, by interpreting the general trends of trajectories observed in sex-disaggregated samples, and comparing within-trajectory symptom course and prevalence rates.

METHOD

We included N = 554 participants (62.5% men, 37.5% women) from a multi-centre prospective cohort of emergency department patients with suspected severe injury. PTSD symptom severity was assessed at 1, 3, 6, and 12 months post-trauma, using the Clinician-Administered PTSD Scale for DSM-IV. Latent growth mixture modelling on longitudinal PTSD symptoms was performed within the sex-disaggregated whole samples. Bayesian modelling with informative priors was applied for reliable model estimation, considering the imbalanced prevalence of the expected latent trajectories.

RESULTS

In terms of general trends, the same trajectories were observed for men and women, i.e. resilient, recovery, chronic symptoms and delayed onset. Within-trajectory symptom courses were largely comparable, but resilient women had higher symptoms than resilient men. Sex differences in prevalence rates were observed for the recovery (higher in women) and delayed onset (higher in men) trajectories. Model fit for the sex-disaggregated samples was better than for the whole sample, indicating preferred application of sex-disaggregation. Analyses within the whole sample led to biased estimates of overall and sex-specific trajectory prevalence rates.

CONCLUSIONS

Sex-disaggregated trajectory analyses revealed limited sex differences in PTSD symptom trajectories within one-year post-trauma in terms of general trends, courses and prevalence rates. The observed biased trajectory prevalence rates in the whole sample emphasize the necessity to apply appropriate statistical techniques when conducting sex-sensitive research.

Adolescent Posttraumatic Growth: A Review

Existing literature on posttraumatic growth following adverse experiences has questioned adolescent capacity to experience such growth given immature cognitive and affective development. The aim of this review was to conduct the first review of the literature regarding post-traumatic growth among adolescents (ages 12-18) to determine whether there is empirical evidence of adolescent post-traumatic growth. Results of the review, conducted according to PRISMA guidelines, are reported to (1) summarize existing support for adolescent post-traumatic growth within available empirical literature, (2) discuss potential moderators of adolescent post-traumatic growth occurrence, and (3) review existing measures of post-traumatic growth. Evidence of adolescent post-traumatic growth was found within three studies with correlational designs and two studies with longitudinal designs. The majority of the literature regarding adolescent post-traumatic growth provides initial support in the form of correlational evidence; however, such support is difficult to empirically establish given the lack of longitudinal studies in this area. Critiques of the extant research and areas for future research are discussed.

Posttraumatic stress disorder and growth: Examination of joint trajectories in children and adolescents

Positive health endpoints are not the opposite of negative endpoints. Previous studies examining posttraumatic stress disorders (PTSD) and posttraumatic growth (PTG) trajectories have overlooked the co-existence of PTSD and PTG, making it difficult to accurately distinguish individuals with various posttraumatic presentations, causing the effects of targeted interventions to be discounted. To fill this gap, the current study sought to examine joint PTSD and PTG trajectories in children and adolescents. Eight hundred and seventy-six Chinese children and adolescents were recruited to complete self-report questionnaires 6, 12, and 18 months after the Ya'an earthquake. Multiple-process growth mixture modeling analysis was used to test the study proposal. Five distinct joint PTSD and PTG trajectory types were found: recovery, growth, struggling, resistant, and delayed symptoms. Female students and students who felt trapped or fearful were more likely to be in the struggling group, and students who experienced injury to themselves or family members were more likely to belong to the delayed symptom group. These findings suggest that postdisaster psychological services should be provided to relieve delayed symptoms in individuals who experience injury to themselves or their family members, and individuals in the struggling group should be supported to achieve growth.

Effects of Autonomic Nervous System Functioning and Tornado Exposure on Long-Term Outcomes of Aggressive Children

This study examined whether pre-disaster indicators of sympathetic and parasympathetic activity moderated the relation between degree of disaster exposure from an EF-4 tornado and changes in the externalizing and internalizing behavior problems of children at-risk for aggression. Participants included 188 children in 4th-6th grades (65% male; 78% African American; ages 9-13) and their parents from predominantly low-income households who were participating in a prevention study when the tornado occurred in 2011. Fourth-grade children who exhibited elevated levels of aggressive behavior were recruited in three annual cohorts. Parent-rated externalizing and internalizing problems were assessed prior to the tornado (Wave 1; W1), and at 4-12 months (W2), 16-24 months (W3), 42-28 months (W4) and 56-60 months (W5) post-tornado. Children's pre-tornado Skin Conductance Level (SCL) reactivity and Respiratory Sinus Arrhythmia (RSA) withdrawal were assessed at W1 using SCL and RSA measured during resting baseline and during the first 5 min of the Iowa Gambling Task (IGT). Children and parents reported their exposure to tornado-related trauma and disruptions at Wave 3. Children displayed less reduction in externalizing problems if there had been higher child- or parent-reported tornado exposure and less RSA withdrawal, or if they had lower parent-reported TORTE and less SCL reactivity or lower SCL baseline. Highlighting the importance of children's pre-disaster arousal, higher levels of disaster exposure negatively affected children's level of improvement in externalizing problems when children had less vagal withdrawal, and when tornado exposure disrupted the protective effects of higher SCL reactivity and higher SCL baseline.

Association between trajectories of personal growth initiative and post-traumatic stress after Hurricane Harvey: A latent growth mixture modeling approach

Studies examining the association between personal growth initiative (PGI) and post-traumatic stress symptoms (PTSS) have often utilized cross-sectional research designs, and as a result, the changes in the levels of PGI and its association with the trajectory of PTSS remain unclear. The current study aimed to (1) explore the different trajectories in both PGI and PTSS and (2) examine the associations of the identified trajectories between PGI and PTSS among individuals. The final sample were 419 adults who were physically residing in the area when Hurricane Harvey made landfall on 26 August 2017. The initial data collection occurred approximately 16 months after the Hurricane, and participants were asked to participate again after 1- and 3-month later. A result from the latent growth mixture modeling revealed that for PGI, the 4-class model was the best-fitting model, and for PTSS, the 3-class model was the best-fitting model. When examining the association between the trajectories of PGI and PSS, individuals classified to higher PGI subgroups were more likely to be associated with the Recovery PTSS subgroup. The current study suggests that disaster survivors with higher PGI were more likely to recover from PTSS, raising an importance of incorporating PGI to alleviate future PTSS.

Impact of Hurricanes on Children With Asthma: A Systematic Literature Review

Following hurricanes, there can be increases in exacerbations of chronic diseases, such as asthma. Asthma is common among children, and many asthma exacerbations can be prevented. This systematic literature review assessed literature describing the impact of hurricanes on children with asthma in the United States. Medline, Embase, Global Health, PubMed, and Scopus databases were searched for peer-reviewed, English-language articles published January 1990 to June 2019 that described the effect of a hurricane on children with asthma. This search identified 212 articles; 8 met inclusion criteria. All 8 were related to Hurricane Katrina, but research questions and study design varied. Articles included information on asthma after hurricanes from cross-sectional surveys, retrospective chart review, and objective clinical testing. Four articles described discontinuity in health insurance, asthma-related health care, or asthma medication use; and 3 articles examined the relationship between mold exposure and asthma symptoms and reported varying results. The eighth study quantified the burden of asthma among people visiting mobile medical units but did not describe factors associated with asthma symptoms. These results highlight opportunities for future research (eg, on more recent hurricanes) and disaster preparedness planning (eg, strategies to prevent health-care discontinuity among children with asthma).

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.

Mental Health Symptoms Unexpectedly Increased in Students Aged 11-19 Years During the 3.5 Years After the 2016 Fort McMurray Wildfire: Findings From 9,376 Survey Responses

In Fort McMurray, Alberta, Canada, the wildfire of May 2016 forced the population of 88,000 to rapidly evacuate in a traumatic and chaotic manner. Ten percentage of the homes in the city were destroyed, and many more structures were damaged. Since youth are particularly vulnerable to negative effects of natural disasters, we examined possible long-term psychological impacts. To assess this, we partnered with Fort McMurray Public and Catholic Schools, who surveyed Grade 7-12 students (aged 11-19) in November 2017, 2018, and 2019-i.e., at 1.5, 2.5, and 3.5 years after the wildfire. The survey included validated measurement scales for post-traumatic stress disorder (PTSD), depression, anxiety, drug use, alcohol use, tobacco use, quality of life, self-esteem, and resilience. Data analysis was done on large-scale anonymous surveys including 3,070 samples in 2017; 3,265 samples in 2018; and 3,041 samples in 2019. The results were unexpected and showed that all mental health symptoms increased from 2017 to 2019, with the exception of tobacco use. Consistent with this pattern, self-esteem and quality of life scores decreased. Resilience scores did not change significantly. Thus, mental health measures worsened, in contrast to our initial hypothesis that they would improve over time. Of note, we observed higher levels of mental health distress among older students, in females compared to male students, and in individuals with a minority gender identity, including transgender and gender-non-conforming individuals. These findings demonstrate that deleterious mental health effects can persist in youth for years following a wildfire disaster. This highlights the need for multi-year mental health support programs for youth in post-disaster situations. The indication that multi-year, post-disaster support is warranted is relatively novel, although not unknown. There is a need to systematically investigate factors associated with youth recovery following a wildfire disaster, as well as efficacy of psychosocial strategies during later phases of disaster recovery relative to early post-disaster interventions.

Anxiety and resilience in the face of natural disasters associated with climate change: A review and methodological critique

In the past two decades, climate change-related natural disasters, such as hurricanes, floods, and droughts have become increasingly frequent and severe, impacting the emotional and psychological well-being of those who are directly or indirectly exposed to them. Despite great interest in understanding differences in anxiety and resilience in response to natural disasters, enthusiasm appears to outstrip empirical clarity, as there remains considerable ambiguity as to determinants of resilient or pathological outcomes following exposure to natural disasters. In addition, there are several major methodological limitations in climate change and related natural disaster research, including the use of univariate analyses, cross-sectional design, and retrospective measures. Keeping these limitations in mind, we first review literature examining the mental health outcomes of natural disasters. Findings suggest that, overall, resilience is more common than pathological outcomes. Second, we use a multi-dimensional framework of resilience to selectively review factors at the event, individual, as well as family and community levels that could help inform resilient or pathological outcomes. Finally, we consider key limitations and future directions for research and practice in the field of anxiety and resilience in response to climate disasters.

Using Panel Data to Understand the Dynamics of Human Behavior in Response to Flooding

Insights into the dynamics of human behavior in response to flooding are urgently needed for the development of effective integrated flood risk management strategies, and for integrating human behavior in flood risk modeling. However, our understanding of the dynamics of risk perceptions, attitudes, individual recovery processes, as well as adaptive (i.e., risk reducing) intention and behavior are currently limited because of the predominant use of cross-sectional surveys in the flood risk domain. Here, we present the results from one of the first panel surveys in the flood risk domain covering a relatively long period of time (i.e., four years after a damaging event), three survey waves, and a wide range of topics relevant to the role of citizens in integrated flood risk management. The panel data, consisting of 227 individuals affected by the 2013 flood in Germany, were analyzed using repeated-measures ANOVA and latent class growth analysis (LCGA) to utilize the unique temporal dimension of the data set. Results show that attitudes, such as the respondents' perceived responsibility within flood risk management, remain fairly stable over time. Changes are observed partly for risk perceptions and mainly for individual recovery and intentions to undertake risk-reducing measures. LCGA reveal heterogeneous recovery and adaptation trajectories that need to be taken into account in policies supporting individual recovery and stimulating societal preparedness. More panel studies in the flood risk domain are needed to gain better insights into the dynamics of individual recovery, risk-reducing behavior, and associated risk and protective factors.

Violence victimization and negative health correlates of youth in post-earthquake Haiti: Findings from the cross-sectional violence against children survey

BACKGROUND

We examined the prevalence of and relationships between violence victimization and negative health correlates of Haitian youth exposed to the 2010 earthquake.

METHODS

Participants were randomly selected 13-24 year-old youth (1457 females; 1459 males) living in Haiti following the 2010 earthquake. Data collected via Haiti's 2012 Violence against Children Survey (VACS) were analyzed.

RESULTS

Participants reported violence victimization in the past 12 months (females: 49.93%; males: 41.68%), moderate-to-severe mental distress (females: 76.56%; males: 66.41%), and suicidal ideation (females: 26.79%; males: 8.05%). Compared to participants without experiences of violence, victims of violence had significantly higher mean number of sexual partners (females: 1.99, 95% CI: 1.81-2.16, p = .02; males: 4.33, 95% CI: 3.50-5.16, p = .03), mental distress (females: 80.39%, p = .01; males: 72.95%, p = .002), and suicidal ideation (females: 36.09%, p < .0001; males: 12.02%, p < .0001). Male victims of violence were more likely to have sex without a condom (26.02%, p = .01) and female victims of violence were more likely to report histories of STIs (28.04%, p = .01), when compared to participants without history of violence.

LIMITATIONS

Data were collected via self-report. Disaster exposure experiences were not assessed. Analysis was correlational and did not control for potential confounding variables.

CONCLUSIONS

Disaster-exposed youth endorsed high levels of violence victimization and negative health correlates. Earthquake survivors who experienced violence were more likely to report negative health correlates. Greater attention to downstream sequelae of natural disasters is needed.

Development of an international data repository and research resource: the Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive

Background: Studies that identify children after acute trauma and prospectively track risk/protective factors and trauma responses over time are resource-intensive; small sample sizes often limit power and generalizability. The Prospective studies of Acute Child Trauma and Recovery (PACT/R) Data Archive was created to facilitate more robust integrative cross-study data analyses. Objectives: To (a) describe creation of this research resource, including harmonization of key variables; (b) describe key study- and participant-level variables; and (c) examine retention to follow-up across studies. Methods: For the first 30 studies in the Archive, we described study-level (design factors, retention rates) and participant-level (demographic, event, traumatic stress) variables. We used Chi square or ANOVA to examine study- and participant-level variables potentially associated with retention. Results: These 30 prospective studies (N per study = 50 to 568; overall N = 5499) conducted by 15 research teams in 5 countries enrolled children exposed to injury (46%), disaster (24%), violence (13%), traffic accidents (10%), or other acute events. Participants were school-age or adolescent (97%), 60% were male, and approximately half were of minority ethnicity. Using harmonized data from 22 measures, 24% reported significant traumatic stress ≥1 month post-event. Other commonly assessed outcomes included depression (19 studies), internalizing/externalizing symptoms (19), and parent mental health (19). Studies involved 2 to 5 research assessments; 80% of participants were retained for ≥2 assessments. At the study level, greater retention was associated with more planned assessments. At the participant level, adolescents, minority youth, and those of lower socioeconomic status had lower retention rates. Conclusion: This project demonstrates the feasibility and value of bringing together traumatic stress research data and making it available for re-use. As an ongoing research resource, the Archive can promote 'FAIR' data practices and facilitate integrated analyses to advance understanding of child traumatic stress.

[Resilience trajectories-examples from longitudinal studies]

BACKGROUND

According to current research concepts resilience can be defined as adaptation to past and ongoing exposure. Accordingly, adaptation to exposure is a dynamic process, which can be different in different population groups. Prospective longitudinal studies provide unique opportunities to investigate resilience processes.

OBJECTIVES

The aim of this article is to define the concept of resilience, describe examples of longitudinal studies investigating resilience in children, adults and older individuals, exemplary describe four ongoing longitudinal resilience studies in which the authors of the article are participating and identify and analyze methodological challenges in empirical resilience research.

MATERIAL AND METHODS

This study was based on a qualitative literature review of published prospective studies investigating resilience listed in PubMed and study protocols of the four longitudinal studies.

RESULTS

The exemplarily described studies have shown that resilience processes are changeable in all age groups and subject to a variety of influencing factors. The specific and potentially age-associated types of alterations have so far been difficult to determine and need further clarification.

DISCUSSION

In view of the dynamic course of resilience, prospective longitudinal studies are urgently needed. Prospective longitudinal studies have the potential to identify resilience mechanisms and predictors of the course of resilience in different population groups, such as children, adolescents, adults and older individuals. Furthermore, resilience research needs to develop an improved and precise assessment of exposure to stressors.

Understanding Open Access Data Using Visuals: Integrating Prospective Studies of Children's Responses to Natural Disasters

Background

As access to open data is increasing, researchers gain the opportunity to build integrated datasets and to conduct more powerful statistical analyses. However, using open access data presents challenges for researchers in understanding the data. Visuals allow researchers to address these challenges by facilitating a greater understanding of the information available.

Objectives

This paper illustrates how visuals can address the challenges that researchers face when using open access data, such as: (1) becoming familiar with the data, (2) identifying patterns and trends within the data, and (3) determining how to integrate data from multiple studies.

Method

This paper uses data from an integrative data analysis study that combined data from prospective studies of children's responses to four natural disasters: Hurricane Andrew, Hurricane Charley, Hurricane Katrina, and Hurricane Ike. The integrated dataset assessed hurricane exposure, posttraumatic stress symptoms, anxiety, social support, and life events among 1707 participants (53.61% female). The children's ages ranged from 7 to 16 years (M = 9.61, SD = 1.60).

Results

Visuals serve as an effective method for understanding new and unfamiliar datasets.

Conclusions

In response to the growth of open access data, researchers must develop the skills necessary to create informative visuals. Most research-based graduate programs do not require programming-based courses for graduation. More opportunities for training in programming languages need to be offered so that future researchers are better prepared to understand new data. This paper discusses implications of current graduate course requirements and standard journal practices on how researchers visualize data.

Trajectories of PTSD symptoms among children who survived the Lushan earthquake: A four-year longitudinal study

BACKGROUND

This study aimed to explore the trajectories of posttraumatic stress disorder (PTSD) symptoms among child survivors of the Lushan earthquake by using latent category growth analysis.

METHODS

In total, 304 students from a school located in Lushan County were assessed by UCLA PTSD-RI at 1.5, 6, 12, 24 and 48 months after the earthquake. The children ages ranged from 9 to 17 years old at the time of the first assessment, and the sample included 140 males and 164 females.

RESULTS

Four trajectories of PTSD symptoms were found, namely, resilience (53.8%), low symptoms (32.6%), recovery (7.0%), and chronic dysfunction (6.6%). Then, a logistic regression analysis that controlled for gender and grade showed that compared with the resilience group, children with an injury or probable acute stress disorder (ASD) were likely to be in the recovery group, children with probable ASD were more likely to be in the low-symptoms group, and children with a bad relationship with their father were more likely to be in the chronic group.

LIMITATIONS

The participants were selected by convenience principle. All children received an intervention after the earthquake.

CONCLUSIONS

These findings suggest that increasing children's social support may relieve children's PTSD symptoms. We should consider both perceived threat and object exposure in future studies. The posttraumatic stress response was very high and was unstable during the first month after the earthquake, which suggests that psychological first aid is necessary in posttraumatic events.

Temporal Transitions in Patterns of Posttraumatic Stress Disorder and Depression Among Adolescents Following the Wenchuan Earthquake

Posttramatic stress disorder (PTSD) and depression are persistent disorders with heterogeneous comorbidity. Cross-sectional design limitations have prevented previous studies from examining symptom pattern transitions, which limits the understanding on the change of mental health over time since trauma. This study examined transition patterns of PTSD and depression comorbidity and assessed the role of personality. PTSD, depression, and personality scales were used to assess 619 adolescents 1 year after the Wenchuan earthquake and then to longitudinally assess 332 adolescents 2 years post-earthquake. Data were analyzed using latent transition analysis and logistic regression. Four PTSD and depression comorbidity patterns were identified at both times: moderate comorbidity, high comorbidity, no symptoms, and depression. Patterns of PTSD and depression changed in 23.4% of adolescents: 4.4% and 7.1% transitioned from no symptoms to depression and from depression to moderate comorbidity, respectively; 7.5% transitioned from moderate comorbidity to depression. Extraversion and conscientiousness were more likely and openness was less likely to be associated with moderate comorbidity symptoms transitioned to depression symptoms. These findings indicated that patterns of PTSD and depression in adolescents are heterogeneous and show temporal change.

The influence of flood exposure and subsequent stressors on youth social-emotional health

Most disaster mental health research focuses on the relationship between disaster exposure and distress, often neglecting its influence on social-emotional health, despite implications for resilience and well-being after the disaster. Following multiple floods in Texas, a sample of 486 youth aged 10-19 years old (M = 13.74 years, SD = 2.57; 52.9% male) completed measures of disaster exposure, life stressors since the disaster, and social-emotional health. Using mixture regression modeling, we examined differences in the relationship between life stressors and social-emotional health across latent classes of disaster exposure (high, moderate, community, and low exposure). After accounting for mean levels of life stressors, the mean levels of social-emotional health did not differ across exposure classes; however, the strength of the relationship between life stressors and social-emotional health did. Youth in the high exposure group had the highest mean level of life stressors since the disaster. Thus, each additional life stressor did not result in changes in social-emotional health, suggesting saturated stress levels. For youth in the moderate and community exposure classes, increases in life stressors did lower social-emotional health, perhaps pushing them into stress overload. For the low exposure group, life stressors did not have an influence. This has implications for postdisaster mental health screening and support, tailored by levels of exposure and attuned to ongoing stressors that may impact long-term social-emotional health.

Patterns of Caregiver Factors Predicting Participation in Trauma-Focused Cognitive Behavioral Therapy

This study examined patterns of caregiver factors associated with Trauma- Focused Cognitive Behavioral Therapy (TF-CBT) utilization among trauma-exposed youth. This study included 41 caregivers (caregiver age M = 36.1, SD = 9.88; 93% African American) of youth referred for TF-CBT, following a substantiated forensic assessment of youth trauma exposure. Prior to enrolling in TF-CBT, caregivers reported on measures for parenting stress, attitudes towards treatment, functional impairment, caregiver mental health diagnosis, and caregiver trauma experiences. Classification and regression tree methodology were used to address study aims. Predictors of enrollment and completion included: attitudes towards treatment, caregiver trauma experiences, and parenting stress. Several caregiver factors predicting youth service utilization were identified. Findings suggest screening for caregivers' attitudes towards therapy, parenting stress, and trauma history is warranted to guide providers in offering caregiver-youth dyads appropriate resources at intake that can lead to increased engagement in treatment services.

Trajectories of posttraumatic stress disorders among children after the Wenchuan earthquake: a four-year longitudinal study

Background: Previous research has demonstrated heterogeneous patterns of posttraumatic stress disorder (PTSD) among children following disasters. However, no clear consensus has been reached regarding the postdisaster trajectories of PTSD among children. Objective: The current study examined the trajectories of PTSD among children after exposure to the Wenchuan earthquake and explored potential predictors of distinct PTSD trajectories. Methods: A four-year longitudinal study was conducted to follow 301 children who were evaluated for PTSD symptoms following the Wenchuan earthquake. Trauma exposure and some pre-existing characteristics were measured at four months after the disaster, and PTSD symptoms were measured at 4, 16, 29, 40 and 52 months after the disaster. The trajectories were identified with Latent Growth Mixture Modelling, and the predictors were explored with multinomial logistic regression. Results: The following three latent PTSD trajectories were found among children: resilient (74.9%), relapsing (17.7%) and recovery (7.5%). Trauma exposure was more likely to be related to a more severe trajectory of PTSD, having experienced prequake trauma was more likely to be related to the recovery trajectory and school 2 was more likely to be related to the relapsing trajectory. Conclusion: These findings provide novel insights into children's postdisaster response patterns. Individual heterogeneity existed in posttraumatic reactions. This longer-term longitudinal study captured more detailed and accurate information about the development of these trajectories. Trauma exposure and previous traumatic experience were linked to malignant development of PTSD.

Neuroticism Predicts a Long-Term PTSD After Earthquake Trauma: The Moderating Effects of Personality

Background: The heartache from the devastating 8.0 magnitude Wenchuan earthquake, which killed nearly 90,000 people in western China, is still felt despite the large-scale recovery and reconstruction of the affected areas. This study investigated the relationships of earthquake-trauma exposures and personality with posttraumatic stress disorder (PTSD), to identify the long-term consequences of the Wenchuan earthquake on the survivors and the risk factors related to chronic PTSD. We hope the findings can contribute to developing new health care prevention and interventions for the survivors. Methods: We collected a sample of 490 people over 3 years after the Wenchuan earthquake, using questionnaires about demographic information and the traumatic experience in earthquake, the Impact of Event Scale-Revised (IES-R), and the Eysenck Personality Questionnaires (EPQ), to find the consequences of the Wenchuan earthquake on the survivors and the potential factors related to the long-term morbidity of PTSD. Result: Traumatic experiences, such as witnessing someone being seriously injured, having your house seriously damaged, and having close relatives severely injured, were associated with developing PTSD. Personality measured by EPQ was also closely related to PTSD. Regression analyses indicated that a potential linear model characterized the relationship between PTSD, neuroticism and psychoticism, yet extraversion/introversion were not significant factors. In the multivariate logistic regression, neuroticism (a continuous variable measured by EPQ) was of more significance in predicting the morbidity of long-term PTSD, compared with other variables [odds ratio (OR) = 1.113, 95% confidence interval (CI) = 1.081-1.146, Wald Value = 50.467, P < 0.001]. The final path diagram built a model indicated the moderating role of personality in the relationship between traumatic experiences and PTSD (CMIN/DF = 2.324, P < 0.001; CFI = 0.879 < 0.8; RMSEA = 0.05 < 0.08). Conclusion: This study demonstrated the role of personality traits and subjective exposure experiences regarding the vulnerability associated with PTSD after earthquake. Among all personality traits, neuroticism is considered a vulnerability factor of PTSD, and other personality traits also moderate the effects of traumatic experiences associated with PTSD. These findings might be useful for psychologists to develop intervention strategies for people suffered natural disasters, and to help individuals with PTSD to heal fully.

Trauma-informed schools: Child disaster exposure, community violence and somatic symptoms

BACKGROUND

Given the increasing prevalence of natural disasters, trauma-informed school settings should include efficient methods for assessing child health and mental health in post-disaster environments. To develop such methods, factors that contribute to children's vulnerability and key signs of distress reactions after disasters need to be understood. To address these issues, we evaluated pre-disaster community violence exposure as a vulnerability factor for children's post-disaster reactions and somatic symptoms as a key post-disaster outcome.

METHODS

We evaluated 426 children exposed to Hurricane Katrina at two timepoints (3-7 months and 13-17 months post-disaster). Structural equation models evaluated community violence exposure, hurricane exposure, and posttraumatic stress and somatic symptoms.

RESULTS

Community violence exposure was associated with increased levels of posttraumatic stress symptoms among disaster-impacted youth, and did not moderate the relationship between disaster exposure and posttraumatic stress symptoms. Posttraumatic stress symptoms were associated with somatic symptoms in the short-term recovery period (3-7 months), but not associated with somatic symptoms during the longer-term recovery period (13-17 months).

LIMITATIONS

This study did not include school-level factors, and somatic symptoms were based on parent reports. The study did not include parent functioning information or distinguish between whether somatic symptoms were medical or functional in nature.

CONCLUSIONS

Post-disaster school-based screeners may need to incorporate questions related to children's past exposure to community violence and their somatic symptoms to provide trauma-informed care for children.

Trajectories of posttraumatic stress disorders among adolescents in the area worst-hit by the Wenchuan earthquake

BACKGROUND

This study examined the trajectories of posttraumatic stress disorder (PTSD) among adolescents in the area worst-hit by the Wenchuan earthquake, and assessed the role of trauma exposure in differentiating distinct PTSD trajectories.

METHODS

In total, 391 adolescents were selected from the Wenchuan and Maoxian counties in Sichuan province (the area worst-hit by the earthquake). Participants completed a trauma exposure questionnaire at 1 year, and the Child PTSD Symptom Scale at 1 year, 1.5 years, 2 years, and 2.5 years after the earthquake.

RESULTS

Three latent PTSD trajectories were found in adolescents: moderate-stable (81.6%), decreasing (8.7%), and increasing trajectories (9.7%). T1 trauma exposure was more likely to be related to the decreasing trajectory group.

LIMITATIONS

All variables were measured by self-report scales. There was high non-random dropout.

CONCLUSION

The course of PTSD was heterogeneous among adolescents following the same natural disaster.

Assessment Tools for the Mental Health of School-Aged Children and Adolescents Exposed to Disaster: A Systematic Review (1988-2015)

Objectives

In this study, we aimed to conduct a systematic review of studies investigating psychosocial factors affecting children exposed to disasters.

Methods

In total, 140 studies were retrieved. The studies were published from 1988 to 2015. A systematic review was performed using the PRISMA guidelines. MEDLINE, EMBASE, Cochrane Central, Web of Science, PsycINFO, PubMed, and Google Scholar were searched. Each database was searched using the following terms: 'Child,' 'Adolescent,' 'Youth,' 'Disaster,' 'Posttraumatic,' 'Psychosocial,' 'Assessment,' 'Evaluation,' and 'Screening.' The identified studies were subjected to data extraction and appraisal.

Results

The database search identified 713 articles. Based on the titles and abstracts, the full texts of 118 articles were obtained. The findings of this review can be used as a basis for the design of a psychosocial evaluation tool for disaster preparedness.

Conclusion

Given the paramount importance of post-disaster evaluation and the weaknesses of current disaster evaluation tools, the need to develop valid and reliable tools and psychometric evaluations cannot be overstated. Our findings provide current evidence supporting various assessments in children, who are very vulnerable psychologically following disasters.

Trajectories of resilience and dysfunction following potential trauma: A review and statistical evaluation

Given the rapid proliferation of trajectory-based approaches to study clinical consequences to stress and potentially traumatic events (PTEs), there is a need to evaluate emerging findings. This review examined convergence/divergences across 54 studies in the nature and prevalence of response trajectories, and determined potential sources of bias to improve future research. Of the 67 cases that emerged from the 54 studies, the most consistently observed trajectories following PTEs were resilience (observed in: n = 63 cases), recovery (n = 49), chronic (n = 47), and delayed onset (n = 22). The resilience trajectory was the modal response across studies (average of 65.7% across populations, 95% CI [0.616, 0.698]), followed in prevalence by recovery (20.8% [0.162, 0.258]), chronicity (10.6%, [0.086, 0.127]), and delayed onset (8.9% [0.053, 0.133]). Sources of heterogeneity in estimates primarily resulted from substantive population differences rather than bias, which was observed when prospective data is lacking. Overall, prototypical trajectories have been identified across independent studies in relatively consistent proportions, with resilience being the modal response to adversity. Thus, trajectory models robustly identify clinically relevant patterns of response to potential trauma, and are important for studying determinants, consequences, and modifiers of course following potential trauma.

Posttraumatic Growth as a Response to Natural Disasters in Children and Adolescents

PURPOSE OF REVIEW

This review examines factors thought to be associated with posttraumatic growth (PTG) (demographic variables, exposure, and family and social processes) among youth exposed to natural disasters, describes the relationship between PTG and posttraumatic stress, and discusses psychological processes (rumination and coping) linked to PTG.

RECENT FINDINGS

Guided by PTG theory and the literature on PTG in adults, research has revealed relationships between PTG and child, environmental, and family and social factors among youth though the results are mixed. Youth's subjective exposure to disasters, their level of posttraumatic stress following the disaster, and the type of psychological processes they employ to cope with the disaster appear to be associated with PTG. Research has garnered preliminary support for PTG in children exposed to natural disasters but additional research is needed to fully explicate these relationships and to understand how these relationships change over time.

Bayesian PTSD-Trajectory Analysis with Informed Priors Based on a Systematic Literature Search and Expert Elicitation

There is a recent increase in interest of Bayesian analysis. However, little effort has been made thus far to directly incorporate background knowledge via the prior distribution into the analyses. This process might be especially useful in the context of latent growth mixture modeling when one or more of the latent groups are expected to be relatively small due to what we refer to as limited data. We argue that the use of Bayesian statistics has great advantages in limited data situations, but only if background knowledge can be incorporated into the analysis via prior distributions. We highlight these advantages through a data set including patients with burn injuries and analyze trajectories of posttraumatic stress symptoms using the Bayesian framework following the steps of the WAMBS-checklist. In the included example, we illustrate how to obtain background information using previous literature based on a systematic literature search and by using expert knowledge. Finally, we show how to translate this knowledge into prior distributions and we illustrate the importance of conducting a prior sensitivity analysis. Although our example is from the trauma field, the techniques we illustrate can be applied to any field.

PTSD and depression in adult survivors of flood fury in Kashmir: The payoffs of social support

Exposure to disasters such as floods predisposes individuals for psychological distress such as posttraumatic stress disorder (PTSD), depression, and anxiety. Researchers exploring the association between flood-exposure and psychopathology attempt to understand the conditions and mechanisms through which potential benefits may occur. One such potential factor that may contribute to resilience in the face of disaster is social support system. However, there is scarcity of researches concerning the protective effects of social support following floods, in adult samples. Thus, the present study examined the moderating and indirect effects of perceived social support from family and friends in the association between flood-exposure and symptoms of PTSD and depression. The study was a cross sectional in nature. Survey data were collected from 87 adult survivors of flood fury in Kashmir valley, aged 30-40. High level of family and friends' support reduced the association between flood-exposure and symptoms of PTSD and depression whereas a low level of such support enhanced this association. Results also suggested that family support carried a significant proportion of variance in predicting depression. Given the potential for negative mental health outcomes following natural disasters, efforts to enhance adults' social support may be especially important.

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.

Long-term health of children following the Eyjafjallajökull volcanic eruption: a prospective cohort study

Background: More than 500 million people worldwide live within exposure range of an active volcano and children are a vulnerable subgroup of such exposed populations. However, studies on the effects of volcanic eruptions on children's health beyond the first year are sparse. Objective: To examine the effect of the 2010 Eyjafjallajökull eruption on physical and mental health symptoms among exposed children in 2010 and 2013 and to identify potential predictive factors for symptoms. Method: In a population-based prospective cohort study, data was collected on the adult population (N = 1615) exposed to the 2010 Eyjafjallajökull eruption and a non-exposed group (N = 697). The exposed group was further divided according to exposure level. All participants answered questionnaires assessing their children´s and their own perceived health status in 2010 and 2013. Results: In 2010, exposed children were more likely than non-exposed children to experience respiratory symptoms (medium exposed OR 1.47; 95% CI 1.07-2.03; high exposed OR 1.52; 95% CI 1.03-2.24) and anxiety/worries (medium exposed OR 2.39; 95% CI 1.67-3.45; high exposed OR 2.77; 95% CI 1.81-4.27). Both genders had an increased risk of symptoms of anxiety/worries but only exposed boys were at increased risk of experiencing headaches and sleep disturbances compared to non-exposed boys. Within the exposed group, children whose homes were damaged were at increased risk of experiencing anxiety/worries (OR 1.62; 95% CI 1.13-2.32) and depressed mood (OR 1.55; 95% CI 1.07-2.24) than children whose homes were not damaged. Among exposed children, no significant decrease of symptoms was detected between 2010 and 2013. Conclusions: Adverse physical and mental health problems experienced by the children exposed to the eruption seem to persist for up to a three-year period post-disaster. These results underline the importance of appropriate follow-up for children after a natural disaster.

Posttraumatic Stress Symptom Trajectories Among Children After Disaster Exposure: A Review

Natural disasters, such as hurricanes and floods, are increasing in frequency and scope. Youth exposed to disasters are at risk for developing posttraumatic stress symptoms (PTSS). However, not all youth who report initially elevated PTSS report persistent PTSS that last beyond the first three to six months postdisaster. Thus, it is crucial to understand how and why youth differ in their patterns of PTSS. This study reviewed the literature on children's postdisaster PTSS, evaluating the typical number and types of patterns for children's PTSS trajectories, as well as risk and protective factors predicting trajectory membership. This review identified eight empirical studies on youth PTSS trajectories following natural disasters; these studies included 8,306 children aged 3 to 18 years. All studies identified resilience, recovery, and chronic trajectories. Evidence for a delayed trajectory was mixed. Proportions of children falling into each trajectory varied widely across studies, but overall, resilience was the most prevalent trajectory. These findings were consistent across study factors (i.e., analytic strategy, assessment timing, and study selection criteria). Female gender, disaster exposure, negative coping, and lack of social support were significant risk factors for chronic trajectories across several studies. Future research should combine individual level participant data across studies of children's responses to disasters to better understand PTSS trajectories.

Posttraumatic Stress Symptoms and Posttraumatic Growth in Children and Adolescents Following an Earthquake: A Latent Transition Analysis

This study examined the transitions in classes of posttraumatic stress symptoms and posttraumatic growth in a sample of children and adolescents (N = 757), between 8 and 20 months after the 2013 Ya'an earthquake in China. Using latent profile analysis, three classes of symptoms (resilient, thriving, and struggling) were identified at 8 and 20 months after the earthquake. Latent transition analysis indicated that the majority of survivors remained in the same class during the period, while others showed a transition between different classes over time. The transition was mainly characterized by three paths: from struggling to resilient, and from thriving to either resilient or struggling. Of the survivors who were classified as thriving at 8 months, those transitioning to the struggling class at 20 months were more likely to experience higher levels of loss and injury compared with those transitioning to the resilient class (Cohen's d = 0.72) or remaining in the thriving class (Cohen's d = 0.36) at 20 months postearthquake. Survivors who remained stable in the struggling class were older than those who remained stable in the thriving class (Cohen's d = 0.41) or those who moved from thriving at 8 months to resilient at 20 months after the earthquake (Cohen's d = 0.39). It is recommended that clinicians consider the classes of posttraumatic stress symptoms and posttraumatic growth, and the potential development paths and associated factors, when implementing interventions for children and adolescents after a natural disaster.

Post-traumatic stress symptoms and post-traumatic growth among children and adolescents following an earthquake: a latent profile analysis

BACKGROUND

Pathological and beneficial outcomes have been documented in children and adolescents exposed to disasters, but the patterns of the outcomes are not known. This study was conducted to identify patterns of post-traumatic stress symptoms and post-traumatic growth and examine the predictors for the patterns among children and adolescents following an earthquake.

METHOD

Self-reported measures (post-traumatic stress symptoms, post-traumatic growth, disaster exposure, and social support) were assessed among a total of 618 participants (age 12.26 ± 2.75) at 8 months post disaster. Latent profile analysis was utilized to identify the patterns of post-traumatic stress symptoms and post-traumatic growth, and multinomial logistic regressions were conducted to examine the predictors for the patterns.

RESULTS

Three patterns were identified. Most of the participants fell into the Thriving pattern and smaller proportions fell into either the Resilient or Stressed and Growing pattern. Loss and injury, subjective fear, and social support could predict the membership in patterns of post-traumatic stress symptoms and post-traumatic growth.

CONCLUSIONS

Practitioners are suggested to identify the pattern of post-traumatic stress symptoms and post-traumatic growth for different children and adolescents, and provide the service targeting their needs.

Schools and Disasters: Safety and Mental Health Assessment and Interventions for Children

This article draws on experiences and lessons from global disasters and utilizes the United Nations Comprehensive School Safety Framework to highlight the necessary role of safe schools in protecting children, as well as adult staff, from the immediate threats and long-term implications of disasters. Specifically, we focus on three well-established pillars of school safety: Pillar I: Safe Learning Facilities; Pillar II: Disaster Management; and Pillar III: Risk Reduction and Resilience Education. In addition, we propose a potential fourth pillar, which underscores the function of schools in postdisaster mental health assessment and intervention for children. We argue that schools offer a central location and trusted institutional space for mental health assessment and intervention after disasters. We also examine the important linkages between schools, child mental health, and household and family recovery. We conclude with recommendations for filling gaps in research and practice related to ensuring the safety of schools and the associated health and well-being of children in the face of future disasters.

Predictors of severe psychological distress trajectory after nuclear disaster: evidence from the Fukushima Health Management Survey

OBJECTIVES

The Fukushima Daiichi Nuclear Power Plant accident, which occurred after the Great East Japan Earthquake and Tsunami in March 2011, may have a considerable long-term impact on the lives of area residents. The aims of this study were to determine the trajectories of psychological distress using 3-year consecutive data, and to find predictive factors of severe distress that may also prove useful for public health intervention.

METHODS

Data were obtained on 12 371 residents who were registered in the municipalities categorised as complete evacuation areas for 3 years after the disaster and who completed an assessment in each of the 3 years.

RESULTS

Using group-based trajectory modelling, we identified four trajectory patterns distinguished by the levels of psychological distress, which gradually improved over time in all trajectories. Subjective sleep insufficiency, problem drinking, poor social support and perception of radiation risk 3 years after the accident were associated with the severity of psychological distress, according to the multivariate analysis.

CONCLUSIONS

The identified factors may be useful for community-based mental healthcare over the long term following a nuclear disaster.

Perceived Changes in Social Relations after Earthquake Trauma among Eastern Anatolian Women: Associated Factors and Mental Health Consequences

In this study, we examined social relations in women exposed to earthquake trauma in Eastern Anatolia, Turkey. We examined women's perceptions regarding the changes in their social relations within their neighbourhood, within their marriage and with their children; analysed the factors that were associated with these relations; and tested the hypothesis that an improvement in social relations will protect women's mental health from the negative impact of earthquake trauma. Participants consisted of a random selection of 1253 women, who were interviewed regarding their psychosocial needs and mental health status 1 year after earthquake. They reported trauma-related changes in their social relations; their mental health was evaluated using the Post Traumatic Stress Diagnostic Scale and Brief Symptom Inventory. Our study demonstrated severe earthquake trauma was associated with deteriorated social relations, especially neighbourhood and marital relations. Deteriorated marital and child relations were associated with increased levels of psychiatric distress; deteriorated neighbourhood relations were associated with intrusive posttraumatic stress symptoms. Improved neighbourhood relations, but not family relations, were able to protect women's mental health from the negative impact of trauma. The results are discussed regarding their relevance to gender effects and the provision of relation-specific and symptom-specific disaster relief. Copyright © 2014 John Wiley & Sons, Ltd.

Mapping concentrations of posttraumatic stress and depression trajectories following Hurricane Ike

We investigated geographic concentration in elevated risk for a range of postdisaster trajectories of chronic posttraumatic stress symptom (PTSS) and depression symptoms in a longitudinal study (N = 561) of a Hurricane Ike affected population in Galveston and Chambers counties, TX. Using an unadjusted spatial scan statistic, we detected clusters of elevated risk of PTSS trajectories, but not depression trajectories, on Galveston Island. We then tested for predictors of membership in each trajectory of PTSS and depression (e.g., demographic variables, trauma exposure, social support), not taking the geographic nature of the data into account. After adjusting for significant predictors in the spatial scan statistic, we noted that spatial clusters of PTSS persisted and additional clusters of depression trajectories emerged. This is the first study to show that longitudinal trajectories of postdisaster mental health problems may vary depending on the geographic location and the individual- and community-level factors present at these locations. Such knowledge is crucial to identifying vulnerable regions and populations within them, to provide guidance for early responders, and to mitigate mental health consequences through early detection of mental health needs in the population. As human-made disasters increase, our approach may be useful also in other regions in comparable settings worldwide.

Operationalising resilience in longitudinal studies: a systematic review of methodological approaches

Over the life course, we are invariably faced with some form of adversity. The process of positively adapting to adverse events is known as ‘resilience’. Despite the acknowledgement of 2 common components of resilience, that is, adversity and positive adaptation, no consensus operational definition has been agreed. Resilience operationalisations have been reviewed in a cross-sectional context; however, a review of longitudinal methods of operationalising resilience has not been conducted. The present study conducts a systematic review across Scopus and Web of Science capturing studies of ageing that posited operational definitions of resilience in longitudinal studies of ageing. Thirty-six studies met inclusion criteria. Non-acute events, for example, cancer, were the most common form of adversity identified and psychological components, for example, the absence of depression, the most common forms of positive adaptation. Of the included studies, 4 used psychometrically driven methods, that is, repeated administration of established resilience metrics, 9 used definition-driven methods, that is, a priori establishment of resilience components and criteria, and 23 used data-driven methods, that is, techniques that identify resilient individuals using latent variable models. Acknowledging the strengths and limitations of each operationalisation is integral to the appropriate application of these methods to life course and longitudinal resilience research.

Research Review: Changes in the prevalence and symptom severity of child post-traumatic stress disorder in the year following trauma - a meta-analytic study

BACKGROUND

Understanding the natural course of child and adolescent posttraumatic stress disorder (PTSD) has significant implications for the identification of, and intervention for, at-risk youth. We used a meta-analytic approach to examine longitudinal changes in youth PTSD prevalence and symptoms over the first 12 months posttrauma.

METHODS

We conducted a systematic review to identify longitudinal studies of PTSD in young people (5-18 years old), excluding treatment trials. The search yielded 27 peer-reviewed studies and one unpublished dataset for analysis of pooled prevalence estimates, relative prevalence reduction and standardised mean symptom change. Key moderators were also explored, including age, proportion of boys in the sample, initial prevalence of PTSD and PTSD measurement type.

RESULTS

Analyses demonstrated moderate declines in PTSD prevalence and symptom severity over the first 3-6 months posttrauma. From 1 to 6 months posttrauma, the prevalence of PTSD reduced by approximately 50%. Symptoms also showed moderate decline, particularly across the first 3 months posttrauma. There was little evidence of further change in prevalence or symptom severity after 6 months, suggesting that it is unlikely a child would lose a PTSD diagnosis without intervention beyond this point.

CONCLUSIONS

The current findings provide key information about the likelihood of posttrauma recovery in the absence of intervention and have important implications for our understanding of child and adolescent PTSD. Results are discussed with reference to the timing of PTSD screening and the potential role of early interventions. Findings particularly highlight the importance of future research to develop our understanding of what factors prevent the action of normal recovery from the 'acute' posttrauma period.
