With the emergence of multisource data and the development of cloudcomputing platforms, accurate prediction of event-scale dust sourceregions based on machine learning (ML) methods should beconsidered, especially accounting for the temporal variability in sampleand predictor variables. Arid Central Asia (ACA) is recognized as one ofthe world’s primary potential sand and dust storm (SDS) sources. In thisstudy, based on the Google Earth Engine (GEE) platform, four MLmethods were used for SDS source prediction in ACA. Fourteenmeteorological and terrestrial factors were selected as influencingfactors controlling SDS source susceptibility and applied in themodeling process. Generally, the results revealed that the random forest(RF) algorithm performed best, followed by the gradient boosting tree(GBT), maximum entropy (MaxEnt) model and support vector machine(SVM). The Gini impurity index results of the RF model indicated thatthe wind speed played the most important role in SDS sourceprediction, followed by the normalized difference vegetation index(NDVI). This study could facilitate the development of programs toreduce SDS risks in arid and semiarid regions, particularly in ACA

Bachkground: The risk factors of Posttraumatic Stress Symptoms (PTSS) and depressive symptoms have been well-established, but whether the network structure of their symptoms changes over time remains unclear. This study aims to examine the six-year changes of network structure of PTSS and depressive symptoms among Wenchuan earthquake adult survivors in China.Methods: In this pooled cross-sectional study, respondents were sampled from the same population at each of the five waves (N = 1343, 1205, 1177, 1376, and 1339). The network structure of them was investigated using network analyses.Results: The study shows network connections stable across waves were the positive connections between hyperarousal and intrusions, hyperarousal and somatic symptoms, and two dimensions of positive effects. Stable negative connections were those between depressed affects and positive effects, avoidance and depressed affects, avoidance with interpersonal symptoms and avoidance with somatic symptoms. Across waves, fearful emotion consistently was the strongest bridge symptom connecting with PTSS symptoms. However, for PTSS the strongest bridge symptom varied across time as it was avoidance in wave 1 but were hyperarousal in other four waves.Limitations: This study was based on a pooled cross-sectional survey, which inhibits conclusions regarding causal influences between symptoms at the individual patient level.Conclusions: The network structure of PTSS and depressive symptoms was partly stable, yet also varied across survey waves. Core symptom clusters for PTSS and depressive symptoms were avoidance and depressed affect, respectively. The central role of these clusters in PTSS and depressive symptoms has important implications to future psychiatric programs.

False denials are sometimes used to cope with traumatic experiences. We examined whether false denials can affect true and false memory production for a traumatic event and conversations surrounding the trauma. One hundred and twenty-six participants watched a trauma analogue video of a car crash before being randomly asked in a discussion with the experimenter to (1) respond honestly or (2) falsely deny that certain details happened in the video. After one week, all participants received misinformation about the discussion with the experimenter and the car crash. Finally, all participants were instructed to respond truthfully in a source memory task. Participants who falsely denied information during the first session were statistically significantly more prone than honest participants to omit details they denied and to report misinformation about what was discussed in the first session. Our work suggests that false denials of a traumatic experience might lead to both forgetting and increased false memory levels for earlier conversations about the event. ispartof: Memory vol:30 issue:9 pages:1158-1171 ispartof: location:England status: Published online

Background Respectful care of bereaved parents after stillbirth plays a pivotal role in enabling the grieving process and reducing the traumatic impact of this life-changing event. Unfortunately, professionals and midwives, in particular, are often emotionally unprepared and frequently left alone when dealing with these stressful events. Aim The BLOSSoM (Burnout after perinatal LOSS in Midwifery) study aims to address the levels of professional burnout in Italian midwives and evaluate the psychological impact of bereavement care on professionals. Methods Web-based cross-sectional study, including socio-demographic questionnaire, survey on the knowledge of guidelines for stillbirth management and two psychometric tests: Maslach Burnout Inventory (MBI) and Impact of Event Scale - Revised (IES-R). Findings Of 445 female midwives, mean age 35.1 (SD 9.9), working years 11.2 (SD 10.2), 149 (33.4%) reported specific training on stillbirth and 420 (94.6%) highlighted the need for further training and support. Medium to high levels of burnout (Emotional Exhaustion) were present in 65 midwives (15.9%) with a high prevalence of Reduced Personal Accomplishment (292, 64.2%). ‘Communicating the diagnosis of death’ was considered the hardest task, followed by ‘assisting the meeting with the baby’; 109 midwives (24.5%) reported high IES-R scores (>30), suggesting symptoms of PTSD related to stillbirth events; a good level of knowledge of guidelines favoured Personal Accomplishment (OR 0.3 [0.1 – 0.6]). The number of stillbirths assisted by midwives was not associated with burnout levels. Conclusion Midwives are particularly at risk of developing professional burnout, as early as after five years of work, with a significant association with the psychological impact exerted by stressful events (stillbirth).

Understanding the processes controlling dissolved reactive phosphorus (DRP) loss in tile-drained systems is essential to better define critical source areas and inform nutrient and conservation practice recommendations. Concentration-discharge (C-Q) relationships have been used to infer solute sources, reactivity, proximity, and transport mechanisms governing solute fluxes. In this study, we compare DRP loads and flow-weighted mean DRP (FDRP) concentrations from P source and sink soils at an annual and event scale, and use power law analysis coupled with index-based approaches in order to identify the predominant DRP C-Q behavior in these soils at a daily and event scale. Results indicate that, in general, P source soils consistently lost higher DRP loads and exhibited greater FDRP concentrations when compared to P sink soils when examined at both annual and event scales. At the daily scale, C-Q patterns were linked to the soil P status whereby a chemostatic (b = 1) and dilution (b

BACKGROUND: Posttraumatic stress disorder (PTSD) is prevalent in patients who have had a cardiac arrest and their partners. Accordingly, acute traumatic stress screening is recommended, but its association with later PTSD symptoms has never been addressed in postresuscitation settings.OBJECTIVE: The aim of this study was to examine whether acute traumatic stress is associated with PTSD symptoms in patients who have had a cardiac arrest and their partners.METHODS: This multicenter longitudinal study of 141 patients and 97 partners measures acute traumatic stress at 3 weeks and PTSD symptoms at 3 months and 1 year after resuscitation, using the Impact of Event Scale. Linear regression models were used to evaluate the association between severity of acute traumatic stress and PTSD symptoms and post hoc to explore effects of group (patients/partners), age, and sex on acute traumatic stress severity. We categorized Impact of Event Scale scores higher than 26 at 3 months and 1 year as clinical severe PTSD symptoms.RESULTS: Higher acute traumatic stress severity is significantly positively associated with higher PTSD symptom severity at 3 months (patients and partners: P < .001) and 1 year (patients and partners: P < .001) postresuscitation, with the strongest association for women compared with men (P = .03). Acute traumatic stress was higher in women compared with men across groups (P = .02). Clinical severe PTSD symptoms were present in 26% to 28% of patients and 45% to 48% of partners.CONCLUSION: Experiencing a cardiac arrest may elicit clinical severe PTSD symptoms in patients, but particularly in their partners. Screening patients and partners for acute traumatic stress postresuscitation is warranted to identify those at increased risk of long-term PTSD symptoms.

Problems duringold age have a direct impact on the mental and social health of the older adults. In this research, we decided to evaluate the effects of group logotherapy training on self-esteem, communication skills, and dealing with events in the older adults. Thesamples of this randomized controlled trial (RCT) include30 older adults individuals with unstable and weak self-esteem in adaily center for the older adults, which were selected by convenience method and divided into two equal groups, i.e., the cases and controls. The Coopersmith Self-Esteem Inventory (CSEI), Weiss and Marmar’s Impact of Event Scale-Revised (IES-R), and Barton’s Communication Skills Questionnaire were the instruments for data collection. After evaluating the baseline, the case group attended ten sessions of group logotherapy. During this period, the controls were only using the conventional programs of the center. At the end of the program, the baseline sessions were completed by all participants at 1 and 3-month follow-up. The collected data were analyzed usinga repeated measures model, independent t-test, and chi-square test.The results show that group logotherapy significantly effect on the improvement of self-esteem, communication skills, and dealing with events in the older adults (P

Objective To investigate the traumatic effects of the COVID-19 pandemic on middle-school students and their parents. Methods This epidemiological cross-sectional study was conducted with middle-school students in Denizli. A questionnaire consisting of the IES-R, CRIES-13 and a sociodemographic data form was delivered online. A total of 1059 participants who fully completed the questionnaire were included for analysis. Results The IES-R total and subdimension scores and the CRIES-13 scores were found to be significantly higher in families with an income level of ≤2,500 TL. The CRIES-13 scores of children were found to be significantly higher in divorced families. No statistically significant difference was determined between the IES-R total and subdimension scores of the parents who were healthcare workers and the CRIES-13 scale scores of their children. Conclusion A statistically significant, positive, moderate relationship was found between the IES-R scale total and subdimension scores of parents and the CRIES-13 scale scores of children. A low socioeconomic level was seen to increase the prevalence of anxiety in adults and adolescents. The children of divorced families were found to be at higher risk of PTSD. Successful management of mental health symptoms in parents will reflect positively on the mental health status of their children.

This study investigated the association between changes in sleep duration after disaster and post-traumatic stress disorder (PTSD) symptoms and the mediating role of resilience on the association.Data were collected from 2951 Korean adults who were victims of a natural disaster and did not have any mental or medical illnesses before the event. They completed a long-term survey on changes in life for disaster victims using computer-aided personal interviews. Changes in sleep duration before and one month after experiencing a disaster were assessed using a self-reported questionnaire. Resilience levels and PTSD symptoms were measured using the Brief Resilience Scale and the Impact of Event Scale - Revised, respectively, and more than 33 of the IES-R score items were defined as significant PTSD symptoms. Multivariate logistic regression was used to examine the associations between changes in sleep duration and PTSD symptoms. Additionally, mediating studies were conducted to identify the role of resilience on the association.Compared with participants without significant PTSD symptoms, those with PTSD symptoms were more likely to be older and female (group without significant PTSD symptom: mean age = 56.12 ± 18.70 years, female sex = 49.24%; group with significant PTSD symptoms: mean age = 60.88 ± 15.66 years, female sex = 59.52%). Compared with disaster victims without changes in sleep duration, those who had shorter sleep duration after disaster had a higher risk of significant PTSD symptoms (OR = 2.89, 95% Cl = 2.31-3.62, p 0.001). In the mediating study, resilience level significantly mediated the relationship between reduced sleep duration and PTSD symptoms (direct effect: β = 0.208, 95% Cl = 0.166-0.250, p 0.001; indirect effect: β = 0.007, 95% Cl = 0.002-0.011, p 0.001; total effect: β = 0.215, 95% Cl = 0.173-0.257, p 0.001).This study revealed that individuals with reduced sleep duration after disaster had a higher risk of PTSD symptoms, while those with increased sleep duration did not. In addition, mediating effects of resilience level on the relationship between reduced sleep duration and significant PTSD symptoms were observed.

The paper is devoted to the role of hares in the composition of hunter's prey in the Upper Palaeolithic of the Russian (East European) Plain. Mammoths and hoofed mammals are traditionally considered as main hunting species for these sites. However, sometimes completely different species come to the fore, while the bones of the “main hunting animals” are presented only in small amounts. We have analyzed the faunistic materials of the sites confined to the basins of the main rivers of the Russian Plain (Dnieper, Desna, Seym, Oka, Don), the chronostratigraphic position of which is justified by radiocarbon dates. As a result of quantitative analysis, the sites were divided into 4 groups, where group 1 comprises the sites with the content of hare bones in relation to all definable bone residues of more than 50%, and group 4 - which does not contain them at all. A set of skeletal elements was also studied and their percentage in the collection was determined. Correlation of the data with the Late Pleistocene event scale showed the absence of a direct relationship between the number of hare bones in sites with climate changes. Throughout the entire Upper Palaeolithic, hares were part of the environment of the ancient population, spreading widely in forest landscapes and decreasing in the tundra-steppes. Hares served as universal game, especially when other types of hunting were limited (for example, during seasonal migrations of other species).

Understanding erosion and sedimentation processes along the drainage network, from hillslopes to rivers and reservoirs, is essential for water resources management and river restoration. This work proposes a novel dynamic evaluation of landscape factor from modeled runoff and erosion rates from physically-based distributed hydrological modelling, to estimate event-scale sediment connectivity. Four precipitation events of moderate intensity were selected and used for model calibration. The results were used to analyze the temporal variability of connectivity and comparison with indices based on catchment relief or land-uses. Although the headwater areas of the hillslopes presented similar values for all simulated events, a progressive increase in sediment connectivity, proportional to the runoff magnitude of the event, was observed. The variability of the event-scale connectivity index was mainly controlled by parameters related to flow (riverbed roughness, rill erodibility and particle diameter) and less by land use and vegetation cover (cover fraction or interrill erodibility). Although features affecting functional connectivity caused variations between events, the obtained results agreed with indices based on relief as landscape factor. This highlights the important role of structural connectivity represented by the catchment topography. However, the proposed methodology is subject to several sources of uncertainty related to event-scale model calibration, the erosion and transport processes considered and the spatial distribution of runoff. Furthermore, the geomorphological threshold for hillslope and rivers can also affect sediment connectivity, especially along the fluvial system. The results of this work highlight important future challenges in a more dynamic understanding of sediment connectivity river basins., This work was financed by ERDF/Spanish Ministry of Science, Innovation and Universities-State Research Agency (AEI)/Project CGL2017-84625-C2-1-R (CCAMICEM); State Program for Research, Development and Innovation focused on the Challenges of Society

Background Communication is key to understanding the emotional state of critical care patients. Objective To analyze the effectiveness of the communicative intervention known as CONECTEM, which incorporates basic communication skills and augmentative alternative communication, in improving pain, anxiety, and posttraumatic stress disorder symptoms in critical care patients transported by ambulance. Methods This study had a quasi-experimental design with intervention and control groups. It was carried out at 4 emergency medical centers in northern Spain. One of the centers served as the intervention unit, with the other 3 serving as control units. The nurses at the intervention center underwent training in CONECTEM. Pretest and posttest measurements were obtained using a visual analog scale to measure pain, the short-version State-Trait Anxiety Inventory to measure anxiety, and the Impact of Event Scale to measure posttraumatic stress disorder symptoms. Results In the comparative pretest-posttest analysis of the groups, significant differences were found in favor of the intervention group (Pillai multivariate, F2,110 = 57.973, P < .001). The intervention was associated with improvements in pain (mean visual analog scale score, 3.3 pretest vs 1.1 posttest; P < .001) and posttraumatic stress disorder symptoms (mean Impact of Event Scale score, 17.8 pretest vs 11.2 posttest; P < .001). Moreover, the percentage of patients whose anxiety improved was higher in the intervention group than in the control group (62% vs 4%, P < .001). Conclusion The communicative intervention CONECTEM was effective in improving psychoemotional state among critical care patients during medical transport.

Recognized risk factors influencing the birth experience and subsequent poor mental health are not addressed among childbearing adolescents, especially minority teens. Our study purpose was to compare birth experiences of three adolescent groups by prevalence and influence of selected risk factors as moderated by racial/ethnic background. Using a birth rating scale and the Impact of Event Scale, birth perception and stress were examined among an equal number of Black, White, and Hispanic adolescents. Surveys completed at 72 hours postpartum showed Black adolescents most at risk for a negative birth experience. Contributing risk factors included depression, trauma, parity, and operative childbirth. Risk factors occur before and after birth; therefore, childbirth educators can promote a positive birth experience via perinatal assessments and interventions.

Purpose The aim of the study was: (1) to determine whether post-traumatic stress symptoms (PTSS) intensification in a spouse/partner is an essential predictor for PTSS intensification in the parents of children who were treated in the NICU during the neonatal period and (2) to indicate the relationship between psychological variables linked to stress intensification and coping styles with PTSS intensification. Design The research sample consisted of 41 couples of parents of infants aged between 3 and 11 months old, who had been treated in a NICU during the neonatal period. The Impact Event Scale – Revised was used to assess PTSS, the Perceived Stress Scale was applied to assess stress, and the Coping Inventory for Stressful Situations was used to measure the coping style. Data were analysed statistically using descriptive statistics, and hierarchical regression was performed to indicate PTSS predictors. Results PTSS intensification in men was 39.17 ± 17.17 points and in women it was 48.93 ± 18.97 points. The majority of the fathers (68.5%) and of the mothers (82.9%) scored more than 33 points in the IES-R scale, which suggests PTSD. Significant PTSS predictors in the fathers were: PTSS intensification in the partner, the level of perceived stress and emotion-oriented coping. Significant PTSS predictors in women were: avoidance-oriented style in stressful situations and PTSD intensification in the father. Conclusion Post-traumatic stress symptoms in a partner is a significant predictor for post-traumatic stress symptoms in the mothers and fathers of children previously treated in NICU. Practice implications Demonstrating a significant correlation between PTSS in a parent and their partner, as well as stress coping has crucial clinical implications both in terms of prevention and diagnosis.

Purpose As men nowadays often attend the delivery of their own child, they also have to go through the labor period. In this study, the condition of the expectant fathers attending labor was evaluated. Methods In 2016, fathers who went through labor with their partners in the University medical center of Mainz were interviewed within the first days after delivery and 6 months later. They received a “Fathers questionnaire” concerning their motivation, the valuation of their attendance, their emotions during labor, and concerning the service in the labor ward. Six months later, they also received the validated Impact of Event Scale questionnaire (IES-R). In total, 318 participants answered the “Fathers’ Questionnaire”, 226 the IES-R. Results Father’s attendance during labor was considered to be beneficial for fathers themselves (254, 79.8%), for the mother (272, 85.5%), for the newborn child (187, 58.8%), for the relationship (234, 73.6%). Only four could not see a purpose in their attendance. 73 men (23%) felt helpless, 47 (14.8%) were overwhelmed by the situation, 116 (36.5%) felt fear, 299 (94%) were happy to be present at birth, 27 (8.5%) felt traumatized by experiencing their partners in labor. According to the IES-R, none of the 226 men surveyed showed all symptoms of post-traumatic stress disorder. Conclusion Childbirth is related to positive and negative emotions. Positive emotions are predominant, but come along with negative feelings. In this survey, posttraumatic stress disorder did not occur among men after delivery. Nevertheless, fathers’ needs should be kept in view.

The transitional impact scale (TIS) was developed to measure the quality and quantity of changes brought about by transitional events. The aim of the present study was to investigate the psychometric properties of the TIS. Study 1 investigated the validity and internal consistency of the TIS among 445 participants (aged 18-73 years) who completed the TIS, beck anxiety inventory (BAI), centrality of event scale (CES), impact of event scale-revised (IES-R), and post-traumatic growth inventory. Study 2 investigated the test-retest reliability of the TIS among 140 university students (70 female; 70 male) who completed a retest of the TIS after a 2-week interval. The two-factor structure (i.e., material change and psychological change) of the TIS proposed by Svob et al. (2014) was confirmed in different age and socioeconomic status groups of a Turkish sample. The TIS was significantly correlated with the BAI, CES, and IES-R. Finally, the TIS had a high test-retest reliability.

Background Post-traumatic stress disorder (PTSD) frequently occurs in survivors of natural disasters, while symptom of depression is related mostly to interpersonal trauma. These conditions are highly correlated and strongly impact adolescent quality of life. This study aimed to explore the relationship among trauma exposure, PTSD symptoms, and/or depression symptoms in adolescent survivors of the 2013 Lushan (China) earthquake. Methods A cross-sectional survey of 2921 adolescents in the Longmenshan seismic fault zone was conducted three years after the Lushan earthquake. Participants were evaluated using the Earthquake Experience Scale, the Adolescent Self-rating Life Events Checklist (ASLEC), the Children's Revised Impact of Event Scale (CRIES-13), and the Depression Self-Rating Scale (KADS-6). Stepwise regression was used to explore relationships between trauma exposure and PTSD or depression symptoms. Results There was a strong correlation between PTSD and depression symptoms, with a 10.7% comorbidity. Earthquake-related exposure, negative life events, prior exposure to the 2008 Wenchuan (China) earthquake, and being left behind by parents all contributed to PTSD and depressive symptoms. Earthquake exposures contributed mainly to PTSD symptoms, while interpersonal traumas contributed mainly to depression symptoms. Conclusion PTSD and depression symptoms strongly correlate in adolescent survivors of the 2013 Lushan earthquake. The high comorbidity between PTSD and depression symptoms may reflect shared risk factors. Natural disasters are more likely to cause PTSD symptoms, while interpersonal traumas are more likely to cause depression symptoms.

Feigning causes personal and societal consequences, in both civil and criminal context. We investigated whether presenting the consequences of feigning can diminish symptom endorsement in feigned Posttraumatic Stress Disorder (PTSD). We randomly allocated non-native English speaking undergraduates (N = 145) to five conditions: 1) Truth tellers (n = 31), 2) Civil context feigners (n = 27), 3) Civil context warned feigners (n = 26), 4) Criminal context feigners (n = 29), and 5) Criminal context warned feigners (n = 32). All feigning groups received a vignette depicting a situation in which claiming PTSD would be beneficial. One vignette referred to the personal injury claim, whereas the second was about the aggravated assault charges. Additionally, one feigning group from each setting received information about the consequences of feigning (i.e., warned feigners). After receiving the instructions, all participants were administered the Self-Report Symptom Inventory (SRSI), a measure of symptom endorsement. Truth tellers endorsed fewer symptoms than all feigning groups, which mostly did not differ. Yet, criminal warned feigners (59%) were significantly less frequently detected on the SRSI as overreporters than other feigning groups (86.2%���89%). Hence, emphasizing the negative consequences of overreporting may diminish symptom endorsement, but only in high-stake situations. The implications and limitations (e.g., online measure administration) of this work are discussed.

Aim: While it is known that being mechanically restrained during hospitalization can, in severe cases, lead to PTSD in individuals with mental illness, less is known about why some develop posttraumatic stress reactions following restraint while others do not. This study examined whether the amount ofexposure to mechanical restraint and patients’ interpretations of the episodes’ centrality to their identity were related to symptoms of PTSD in individuals with schizophrenia. Methods: We asked 20 individuals to recall mechanical restraint episodes and rate them on centrality to identity. They also completed scales measuring symptoms of posttraumatic stress, depression, trauma history, and were rated on positive and negative symptoms. Objective information about thenumber of times they had been restrained was obtained through Danish health registries. Results: Amount of exposure to mechanical restraint was not significantly related to PTSD symptoms, potentially due to limitations of our small sample. However, interpreting episodes as more central toidentity was. This relationship remained significant when controlling for trauma history, positive symptoms, and depression. Conclusion: The results suggest that clinically significant levels of PTSD are common in this population,and that considering patients’ subjective interpretations of restraint episodes, and not merely the objective facts surrounding them is important for patients’ psychological adjustment.

Purpose: This is a cross-sectional observational study that aims to evaluate the impact of the COVID-19 pandemic in pregnant women.Method: A form containing the validated Impact of Event Scale - Revised questionnaire was sent to the participants.Results: From the 106 participants, 13 had been contaminated by the Sars-Cov2 virus during the pregnancy. More than half of the women (51.89%) presented some degree of psychological impact, 20 participants were classified as having a mild impact, 6 with moderated impact and 29 with severe impact. The psychological impact was more prominent in women in their third gestational trimester, 36.07% of these women presented a severe impact, 4.92% a moderated impact and 14.75% a mild impact. The IES-R questionnaire had a mean score of 35.62 in the group of contaminated patients, indicating a higher psychological impact in comparison with the mean score of 26.76 in the group of patients who were not contaminated by the virus.Conclusion: It can be inferred that the pregnant women who were not contaminated by the Sars-Cov2 presented a lower psychological impact than those who were contaminated. In addition, patients with lower psychological impact did not miss their ultrasound exams. Furthermore, more than half of the women who participated in the study, whether they were contaminated or not, presented some degree of psychological impact.

Background: This study examines changes over time in post-traumatic stress disorder (PTSD) among children who survived the 2008 Wenchuan earthquake and the relevant predictive variables.Methods: A total of 203 children and adolescents were investigated 24 months after the earthquake, and 151 children and adolescents completed the 1-year follow-up study. Participants completed the Children's Revised Impact of Event Scale (CRIES-13), the Center for Epidemiologic Studies Depression Scale (CES-D) and the Connor-Davidson Resilience Scale (CD-RISC). Hierarchical linear regression analysis was used to evaluate the predictors of changes in PTSD severity.Results: Eighty percent of the children still had some PTSD symptoms 2 years after the Wenchuan earthquake, and 66.25% of the children had symptoms that lasted 3 years. In the model predicting PTSD symptom severity, the loss of family members and child burial explained a significant 21.9% of the variance, and depression explained a significant 16.7% of the variance. In the model predicting changes in PTSD severity, the change scores for resilience and depression explained a significant 18.7% of the variance, and cognitive behavioral therapy (CBT) explained a significant 33.6% of the variance.Conclusions: PTSD symptoms in children and adolescents can persist for many years after trauma. In addition to using psychological interventions to improve PTSD symptoms, improvements in depression and resilience should also be considered.

The characteristics (magnitude and timing) of individual rainfall erosivity (RE) events in Europe strongly control soil loss at timescales from the individual event to long term annual average. While annual averages of soil erosion encompass the long-term variability of the event-based drivers of soil erosion (soil condition, water kinetic energy, vegetation properties), they provide both little direct information on the timing of soil loss or capacity to fully understand future erosion. Across the spectrum of empirical to physically based process models, event-scale estimates of rainfall energy are vital. The (R)USLE EI30 index is a popular description of the combined effect of rainfall kinetic energy and the maximum 30-minute intensity of a rainfall event on soil loss. Modelling RE from daily or event rainfall accumulation seeks to capture the intra-annual meteorological controls on the EI30 index, with the goal of utilising rainfall data with higher abundance (eg daily) than conventional but less common hyetograph data. To date, no systematic study has provided model parameter surfaces for Europe’s climatic regions and investigated their spatial configuration. For each of 74 relevant environmental strata (EnS) within 13 broader environmental zones, we calibrate and validate 5 power-law based models with monthly and annual parameter sets using the REDES dataset, composed of over 300,000 RE events from national gauge networks.We demonstrate the applicability of delineated environmental strata for subsampling and modelling event rainfall erosivity with heterogeneous national gauge data coverage and extent. Power-law model fits with 12 individual monthly parameter sets outperformed annual models with periodic cosine functions. The power-law α and β parameters are generally correlated through space (r = 0.66) and follow the general European trend of long-term annual average RE, increasing from North-West to South-East. The average annual Nash-Sutcliffe model efficiency for all strata increased from 0.427 (max: 0.76, min: 0.21) to 0.437 when the top 1 percentile of events were removed, which contribute between 8 and 27% of the total RE per stratum. The prediction capacity was higher in autumn and winter than in spring and summer when rainfall holds generally higher unit kinetic energy. Average model efficiency per environmental zone depended on both the rainfall stochasticity and size of the national data sample within each stratum, highlighting the importance of ample data extents for predicting event rainfall erosivity in Europe.

In mixed bedrock-alluvial rivers, the response of the system to a flood event can be affected by a number of factors, including coarse sediment availability in the channel, sediment supply from the hillslopes and upstream, flood sequencing, and coarse sediment grain size distribution. However, the impact of along-stream changes in channel width on bedload transport dynamics remains largely unexplored. We combine field data, theory, and numerical modeling to address this gap. Observations from two flood events in the Daan River gorge in western Taiwan suggest that coarse sediment evacuation and re-deposition can cause intra-flood changes of up to several meters in channel bed elevation that are distinct from measured before/after bed changes. We hypothesize that this could be related to the abrupt change in width between the 1 km long bedrock gorge and the river upstream and downstream. An analysis of the theoretical relationships between discharge, channel width, and bedload transport capacity shows that for a given slope, narrow channels transport bedload more efficiently than wide ones at low discharges, while wider channels are more efficient at high discharges. We used the model sedFlow to explore this effect, running a random sequence of floods through a channel with a narrow gorge section bounded upstream and downstream by wider reaches. Channel response to imposed floods is complex, as high and low discharges drive different spatial patterns of erosion and deposition, and the channel may experience both of these regimes during the peak and recession periods of each flood. Our modeling suggests that width differences alone can drive substantial variations in sediment flux and bed response, without the need for variations in sediment supply or mobility. Further, the deposition or erosion that takes place within a flood is often not reflected in the before/after changes to the bed, and this disconnect increases with increasing flood size.

Background As any traumatic event, avalanches could trigger psychological disorders on survivors. Our objectives were to determine the prevalence of post-traumatic stress disorder among avalanche survivors and to evaluate post-traumatic stress disorder risks factors as well as the impact on quality of life. Methods A multicentre study was conducted in victims included in the North Alpine Avalanche Registry from 2014 to 2018. Data were collected through a standard questionnaire during semi-directed phone interviews. The primary outcome was the total score on the Impact of Event Scale Revised. Secondary outcomes were the Mental Component Scale and the Physical Component Scale scores of the Short Form 12 questionnaire. Results During the study period, 132 of 211 victims survived. Among the 107 victims included, 55 (51.4%) phone interviews were obtained. Six patients (10.9, 95% CI 1.76–20.05) had an Impact of Event Scale Revised score ≥ 33 indicating a strong probability for post-traumatic stress disorder. Median Mental Component Scale score was 39.0 (IQR 30.5–46.3) for post-traumatic stress disorder patients and 40.1 (IQR 36.5–43.4) for non post-traumatic stress disorder (p = 0.76). Median Physical Component Scale score was 39.4 (37.2–44.3) for post-traumatic stress disorder patients and 44.2 (39.1–46.8) for non post-traumatic stress disorder (p = 0.39). No significant difference in the quality of life in both populations was observed, and no independent risk factors of post-traumatic stress disorder was identified. Conclusion Avalanche accidents may induce post-traumatic stress disorders among survivors in a comparable prevalence to the most traumatic event already studied. Early recognition and preventive measures should be set up in order to reduce the psychological burden in these victims. Trial registration NCT03936738.

Aim To evaluate health-related quality of life, mental health and treatment-related stress responses in children with primary antibody deficiency and both their parents. Methods Children and their parents completed the standardised questionnaires Pediatric Quality of life Inventory, Strength and Difficulties Questionnaire and Impact of Event Scale. Parents also completed standardised questionnaires regarding their own mental health and quality of life. The results were compared to those of healthy children, kidney transplanted children and children in remission from acute lymphoblastic leukaemia. Results Children with primary antibody deficiency reported a poorer health-related quality of life compared to healthy children and children in remission from acute lymphoblastic leukaemia. They reported poorer mental health compared with healthy children. Mothers of children with primary antibody deficiency reported poorer mental health compared to mothers of healthy children but comparable to mothers of chronically ill children. Parents reported a similar quality of life as the general Norwegian population. Treatment with subcutaneous immunoglobulin infusions at home is generally well tolerated, but some report severe treatment-related stress. Conclusion Primary antibody deficiency has a significant impact on quality of life and mental health of affected children. Patients and parents with severe treatment-related stress should be identified and helped.

Objective: We aimed to conduct a comparative analysis of the psychological stress experienced by healthcare workers, frontline workers, and the general public and to assess the factors associated with psychological stress in each of these groups.Methods: We conducted an online survey targeting healthcare workers, frontline workers, and the general public. Psychological stress was assessed with the revised impact of event scale (IES-R). Univariable and multivariable logistic regression analyses were conducted.Results: We surveyed 1,336 participants (64.6% female; mean age, 36.6). The occupation group distribution of respondents was 50.7% healthcare workers, 27.2% frontline workers, and 22.1% general public. The healthcare (23.6 ± 15.8) and frontline (23.6 ± 17.8) workers had higher IES-R scores than the general public (15.3 ± 10.6; p < 0.01). Poor health perception and perception of infection avoidance were associated with psychological stress in the healthcare and frontline workers, but not in the general public.Conclusion: Both healthcare and frontline workers are suffering elevated psychological stress, compared to the general public, and this elevated stress may be related especially to their perceptions of their own health and infection risk. Interventions addressing these factors should be developed to alleviate psychological stress in these populations, and thus reduce their risk of mental illness pathogenesis.

Highlights • The psychological impact of COVID-19 crisis has remained stable during the lockdown. • Symptoms of frequent mental disorders were reported by 35-50% of participants. • Anxiety, depression and above all stress levels have risen from the COVID-19 outbreak. • Daily physical activity may be included as a complement to reduce symptomatology., Background Strict confinement and social distancing measures have been imposed due to the COVID-19 pandemic in many countries. The aim was to assess the temporal evolution of the psychological impact of the COVID-19 crisis and lockdown from two surveys, separated by one month, performed in Spain. Methods Symptoms of depression, anxiety and stress, and the psychological impact of the situation were longitudinally analyzed using the Depression Anxiety and Stress Scale (DASS-21) and the Impact of Event Scale (IES) respectively. Results There was a total of 4,724 responses from both surveys. Symptomatic scores of anxiety, depression and stress were exhibited by 37.22%, 46.42% and 49.66% of the second survey respondents, showing a significant increase compared to the first survey (32.45%, 44.11% and 37.01%, respectively). There was no significant longitudinal change of the IES scores, with 48.30% of the second survey participants showing moderate to severe impact of the confinement. Constant news consumption about COVID-19 was found to be positively associated with symptomatic scores in the different scales, and daily physical activity to be negatively associated with DASS-21 scores. Conclusions Results indicated a temporal increase of anxiety, depression and stress scores during the COVID-19 lockdown. Factors such as age, consumption of information about COVID-19 and physical activity seem to have an important impact on the evolution of psychological symptoms.

Type 1 diabetes is a challenge for children, adolescents, and their families as it affects the quality of life and lifestyle of the whole family context. Diabetes onset and its chronic management could be therefore particularly related to post-traumatic stress disorder (PTSD), a group of persistent psychological and physiological symptoms due to a traumatic and severe event. The aim of this study was to assess the rate of PTSD in a group of pediatric patients with T1DM and to evaluate the relationship between parental trauma and quality of life. Forty-nine prepubertal children affected by T1DM and their families were consecutively enrolled in the study. Patients and parents were asked to complete two types of questionnaires: (1) The Impact of Event Scale (IES) questionnaire for the evaluation of PTSD. (2) The PedsQL™3.0 Diabetes Module questionnaire to measure diabetes-specific QOL in both children and their parents. Our data suggest that a clinical level of trauma is present in 66.7% of mothers and 65.5% of fathers of T1D children. Parents with medium or high IES Scores demonstrated lower levels of QoL. The results of this study show a high prevalence of acute post-traumatic stress symptoms in parents of prepubertal children with T1DM. This finding is consistent with data from adult diabetic patients. Our data demonstrated also a relation between parents’ level of traumatism and declared QoL scores. Indeed, our data confirm that the duration of diabetes negatively correlates with the QoL by both, parents and patients.

Event centrality, as measured by the Centrality of Event Scale (CES), refers to the degree to which a salient traumatic memory becomes central to individual identity. The current investigation modified the CES to capture valence (positive vs. negative) of event centrality (i.e., CES-V) and determine whether the valence of event centrality for traumatic events differentially relates to trauma responses (i.e., posttraumatic stress disorder [PTSD], posttraumatic growth [PTG]). Trauma-exposed community members (n = 512) completed measures of trauma experiences, PTSD, PTG, and the CES-V. Exploratory factor analysis supported the use of the CES-V. Trauma outcome response profiles were compared between event centrality valence group (i.e., central-positive, not central, central-negative) and factors influencing event centrality valence were explored. Most participants appraised their trauma as central and positive (54.7%), while others appraised their trauma as central and negative (32.8%) or not central (12.5%). Central-positive event centrality ratings were positively related to PTG and inversely related to PTSD, whereas central-negative event centrality ratings were positively related to PTSD and inversely related to PTG. The central-positive group reported the most PTG, and the central-negative group reported the most PTSD. Future research should explore the clinical utility of using event centrality valence to predict trauma responses and track treatment progress.

We used a suite of physical, chemical and biological datasets to assess the influence of upwelling/downwelling on enrichment and primary productivity in shelf waters of the eastern Great Australian Bight at seasonal and event scales. Results showed that the length of an upwelling season did not dictate its intensity or productivity, and that long seasons were not necessarily the most intense or productive. At the event scale, temperature and salinity were found to be better indicators of enrichment of shelf waters than wind stress, with temperatures 2 µm) and bursts of primary productivity (up to ∼ 700 mg C m−2 d−1). A key finding of this study was the importance of differentiating between upwelling events and enrichment events. The former occurred in the early upwelling season (November-December) and were demonstrated by periods of positive wind stress. The latter only occurred in the late upwelling season (January – April), and saw water with temperatures

We develop and implement a novel numerical water tracer model within the Noah LSM with multiparameterization options (WT-Noah-MP) that is specifically designed to track individual hydrometeorological events. This approach provides a more complete representation of the physical processes beyond the standard land surface model output. Unlike isotope-enabled LSMs, WT-Noah-MP does not simulate the concentration of oxygen or hydrogen isotopes, or require isotope information to drive it. WT-Noah-MP provides stores, fluxes, and transit time estimates of tagged water in the surface–subsurface system. The new tracer tool can account for the horizontal and vertical heterogeneity of tracer transport in the subsurface by allowing partial mixing in each soil layer. We compared model-estimated transit times at the H. J. Andrews Experimental Watershed in Oregon with those derived from isotope observations. Our results show that including partial mixing in the soil results in a more realistic transit time distribution than the basic well-mixed assumption. We then used WT-Noah-MP to investigate the regional response to an extreme precipitation event in the U.S. Pacific Northwest. The model differentiated the flood response due to direct precipitation from indirect thermal effects and showed that a large portion of this event water was retained in the soil after 6 months. The water tracer addition in Noah-MP can help us quantify the long-term memory in the hydrologic system that can impact seasonal hydroclimate variability through evapotranspiration and groundwater recharge.

The aim of this study was to investigate whether the level of reported post-traumatic stress (PTSD) symptoms among targets of workplace bullying differ depending on their educational level. Exposure to workplace bullying was assessed by the behavioural experience method and the self-labelling method among 563 Danish employees. PTSD symptoms were assessed by the Impact of Event Scale – Revised. Educational level was measured as years of education. The results showed that workplace bullying was significantly associated with the reporting of PTSD symptoms. However, PTSD symptoms were not reported differently among those with experience of workplace bullying. Implementing bullying policies is an important step in promoting a healthy psychosocial working environment. All targets of workplace bullying would benefit from interventions aiming to reduce progression of PTSD symptoms.The aim of this study was to investigate whether the level of reported post-traumatic stress (PTSD) symptoms among targets of workplace bullying differ depending on their educational level.

Heavy rainstorms play a central role in the water-driving soil erosion processes. An in-depth knowledge about temporal and spatial erosivity of rainfall events is required to gain a better understanding of soil erosion processes and optimize soil protection measures efficiency. In this study, the spatiotemporal distribution of more than 300,000 erosive events measured at 1181 locations, part of the Rainfall Erosivity Database at European Scale (REDES) database, is studied to shed some new light on the rainfall erosivity in Europe. Rainfall erosive events are statistically investigated through the Lorenz curve and derived coefficients such as the Gini coefficient (G). Additionally, seasonal characteristics of the most and the less erosive events are compared to investigate seasonal characteristics of rainstorms across Europe. The G shows largest values of inequality of the inter-annual temporal distribution of the rainfall erosive events in the Alpine region, mostly due to the large number of rainfall events with smaller rainfall erosivity. While for other parts of Europe, the inequality described by the G is mostly due to a small number of high erosive events. The G slightly decreases from south to north while no clear regional patterns can be detected. Additionally, in Europe, on average 11% (ranging from 1 to 24%) of all erosive events contribute to form 50% of the total rainfall erosivity. Furthermore, higher erosive rainfall events tend to occur later in the year compared to less erosive events that take place earlier. To our knowledge, this study is the first one addressing event scale rainfall erosivity distribution using more than 300,000 rainfall erosivity events and covering almost a whole continent. Scientifically our findings represent a major step towards large-scale process-based erosion modelling while, practically, they provide new elements that can support national and local soil erosion monitoring programs.

During their professional tasks, railway workers face stressful situations that can elicit posttraumatic stress and chronic job stress. This study aims to identify burnout level and the existence of PTSD among railway workers, comparing participants with and without experience of accidents at work. Using a sample of 293 railway workers, we applied sociodemographic and professional questions, the Maslach Burnout Inventory and the Impact of Event Scale – Revised. We found moderate levels of burnout, with 56% of the participants presenting high emotional exhaustion. Post-traumatic stress disorder presented moderate levels, but 32% of the sample already revealed trauma symptoms. We found that 60% of the sample has experience of accidents, presenting more emotional exhaustion and high values for all trauma dimensions. The more recent the accident, the greater are psychological avoidance and trauma symptoms, warning of the need to prevent psychological illness in the long-term., Os profissionais que trabalham na ferrovia enfrentam situações stressantes potenciadoras de stress pós-traumático e de stress crónico no trabalho. Pretende-se conhecer o nível de burnout e a existência de stress pós-traumático, comparando os resultados em função da vivência de acidentes no trabalho. Aplicaram-se a 293 profissionais da ferrovia questões sociodemográficas e profissionais, o Maslach Burnout Inventory e a Impact of Event Scale – Revised. Encontraram-se níveis moderados de burnout, nos quais se destacam 56% dos inquiridos com exaustão emocional elevada. O stress pós-traumático apresentou níveis moderados mas 32% da amostra tem já sintomas de trauma. Verificou-se que 60% da amostra tem experiência de acidentes, apresentando mais exaustão emocional e valores superiores em todas as dimensões do trauma.

The present study evaluates the back translation in Urdu and factor structure of Impact of Event Scale-Revised. The scale was administered to 446 adolescents in Pakistan with modifications to the time frame. Indirect traumatic exposure had occurred over six months to 2 years ago. Cronbach alpha coefficients of .78 for Intrusion subscale, .74 for Avoidance subscale and .66 for Hyperarousal subscales; and .88 for total scale scores are reported. Principal component analysis revealed a 3-factor solution explaining 45 % of the variance; factor structure was not similar to the proposed theoretical structure of IES-R. Endemic characteristics and cultural setup of the country highlight need to understand development and expression of trauma in the cultural milieu and direct future research for intervention strategies in schools. Keywords: Indirect exposure, trauma, adolescents, factor structure.
