Trajectories and comorbid symptom networks of posttraumatic stress symptoms in frontline rescuers: A longitudinal study

BackgroundPrevious research has largely lacked studies that explore the trajectories of Posttraumatic stress symptoms (PTSS) and the structure of comorbid psychiatric symptom networks following traumatic event, while controlling for the severity of traumatic exposure. The present study aims to explore the characteristic trajectories of PTSS, in the context of ensuring controlled levels of traumatic exposure. Furthermore, the PTSS, depressive, and anxiety comorbid symptom networks of different PTSS trajectory subgroups are also investigated. MethodsA total of 296 frontline rescue personnel were enrolled into our study. In an effort to control for variations in traumatic exposure severity, this study ensured that all participants had same responsibilities and cumulative operational duration at the post-disaster rescue circumstance. Growth mixture models (GMMs) were employed to scrutinize the trajectories of PTSS. Additionally, network analysis was used to examine the comorbid symptom network of PTSS, depression, and anxiety. ResultsFour distinct PTSS trajectories were identified, namely Persisting Symptom, Gradual Recovery, Gradual Aggravation, and Asymptomatic. Although both the Persisting Symptom and Gradual Aggravation groups belong to the high-risk subgroups for persistent PTSS, they exhibit differences in core symptoms within their respective networks. The core symptom for the Persisting Symptom Network is flashbacks, while for the Gradual Aggravation Network, it is sleep disturbances. ConclusionTo the best of our knowledge, the present study represents the first research endeavor to integrate longitudinal trajectory analysis of PTSS with longitudinal symptom network analysis, clarifying the evolving features of PTSS but also offering valuable insights for early screening and intervention strategies.

A prospective longitudinal study of post-traumatic stress symptoms and its risk factors in newly diagnosed female breast cancer patients

BackgroundPost-traumatic stress symptoms are one of the most commonest, but un-recognized psychological morbidity found in female breast cancer patients. However, there are insufficient prospective studies concerning the trajectory of post-traumatic stress symptoms and their risk factors in Nigerian women living with breast cancer.ObjectiveTo determine the changes in the prevalence and risk factors of post-traumatic stress symptoms among newly diagnosed female breast cancer patients across different timelines over 6 months.MethodThis was a prospective longitudinal study of 183 newly diagnosed female breast cancer patients selected using a systematic random sampling method. The Six-Item Impact of Events Scale, Visual Analogue Scale of Pain, Functional Assessment of Cancer Therapy-Breast, and a Socio-Demographic questionnaire were administered to the participants.ResultsThe prevalence of post-traumatic stress symptoms was 46%, 31%, and 22% at baseline, 3 months, and 6 months respectively, indicating a decline in post-traumatic stress symptoms over time. In the final assessment at 6 months, identified risk factors of post-traumatic stress symptoms were: religiosity, accessibility to treatment, illness perception, chemotherapy, and quality of life.ConclusionPost-traumatic stress symptoms are prevalent in newly diagnosed female breast cancer patients, there is a need for regular screening of these symptoms in these women to allow for early psycho-social intervention, and better treatment outcomes.

Trajectories of Traumatic Stress Symptoms Among Siblings of Children With Cancer: The First Two Years Post-Diagnosis.

Identify and describe trajectories of cancer-related posttraumatic stress symptoms (PTSS) among siblings of children with cancer within two years of diagnosis. Siblings (aged 8-18; M = 11.2 years) across the United States, and for each, one caregiver, were recruited for a cohort sequential longitudinal study with three data collection points six months apart beginning at 6- or 12-months after cancer diagnosis. Siblings (N = 229; 42% of eligible/approached; 53% identifying as female; 68% identifying as non-Hispanic White) completed the Child Posttraumatic Stress Disorder Symptom Scale. Caregivers completed the Strengths and Difficulties Questionnaire (SDQ). Latent class growth analysis (LCGA) and growth mixture modeling (GMM) identified PTSS patterns across time. Fit statistics supported models with three to five PTSS trajectories. The three-class LCGA model included a large mild PTSS group (61%), a moderate PTSS group (35%), and a small (4%) stable severe PTSS group. The four-class LCGA and three- and four-class GMM included groups improving from moderate to mild PTSS (7-21%) and worsening to moderate PTSS across time (12-17%). Across models, siblings with mild PTSS had fewer caregiver-reported emotional and behavioral difficulties on the SDQ. A large group of siblings of children with cancer demonstrate resiliency, however, substantial subsets experience patterns of PTSS that include levels in the moderate-to-severe range during the first two years post-diagnosis. Future research should examine these patterns in more diverse/representative samples and identify factors associated with increasing and sustained severe PTSS to inform intervention targets and reduce cancer-related burden on families.

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

ABSTRACT 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.

Association between housing damage, present bias and delayed-onset post-traumatic stress symptoms among older adults 9 years after a natural disaster

BackgroundPrevious studies suggest that experience of natural disasters may heighten present bias. Research also suggests that impaired self-control (in particular, heightened present bias) could be linked to delayed-onset post-traumatic stress...

Characteristics and Correlates of Ten-Year Trajectories of Posttraumatic Stress Symptoms in Older U.S. Military Veterans

ObjectivesTo examine the nature and correlates of 10-year trajectories of posttraumatic stress disorder (PTSD) symptoms in older U.S. military Veterans. Design and SettingA nationally representative web-based survey of older U.S. Veterans who participated in the National Health and Resilience in Veterans Study over 5 waves between 2011 and 2021. ParticipantsA total of 1,843 U.S. Veterans aged 50 and older (mean age = 67). MeasurementsPTSD symptoms were assessed using the PTSD Checklist. Self-report measures at baseline assessed sociodemographic characteristics; trauma exposures; psychiatric and substance use disorders; mental, cognitive, and physical functioning; and psychosocial factors including expectations of aging. Latent growth mixture modeling identified the nature and correlates of 10-year PTSD symptom trajectories. ResultsMost of the sample had no/low PTSD symptoms (88.7%), while 6.0% had consistently subthreshold symptoms, 2.7% consistently high symptoms, and 2.6% increasing symptoms. Relative to the no/low symptom group, the subthreshold and high symptom groups reported more medical conditions and cognitive difficulties, with younger age and more lifetime traumatic events additionally linked to the high symptom trajectory. Relative to the no/low symptom group, Veterans with increasing symptoms were more likely to report functional disability and lifetime nicotine use disorder, cognitive difficulties, negative expectations regarding physical and emotional aging, and traumatic events over the study period. ConclusionsDespite high rates of trauma exposure, most older Veterans do not evidence symptomatic PTSD trajectories; however, about 11% do. Results underscore the importance of assessing PTSD symptoms in this population and considering longitudinal trajectories as well as associated risk and protective factors.

The Asia Pacific Disaster Mental Health Network: Collaborative Research to Advance Mental Health and Community Resilience

Introduction:The mental health consequences of health emergencies and disasters have the potential to be sustained and severe. In recognition, the 2018 Kobe Expert Meeting on Health Emergency and Disaster Risk Management (Health EDRM), prioritized mental health as one of the key research areas of Health EDRM, to be addressed in a multi-country research project supported by WHO (Kayano et.al., 2019). As climate change, growing urbanization, population density and viral transmission generate increasingly severe hazards, attention to mental health will be critical.Method:The Asia Pacific Disaster Mental Health Network was established in 2020 to foster advancements in mental health research and policy in the region. Building connections between researchers, practitioners and policy makers, the Network includes broad representation from interdisciplinary scholars and organizations across eight Asian and Pacific nations. A research agenda was designed in early meetings, and collaborative research projects were established.Results:The Network has supported the development of innovative disaster mental health research investigating community engagement in recovery, psychosocial interventions, and evaluation frameworks. A recent multilingual systematic review of more than 200 longitudinal studies identified the long-term trajectories of post-traumatic stress symptoms, depression and anxiety following disasters and pandemics (Newnham et al., 2022). Synthesized evidence of risks related to age, gender and disaster type were determined to inform intervention targets.Conclusion:The Asia Pacific Disaster Mental Health Network established a platform for scholarly connection, intervention planning and knowledge dissemination. This presentation will provide an overview of the Network’s activities, and research highlights that have identified targeted points for policy and practice.

Posttraumatic Stress Symptom Trajectories in Family Caregivers of Patients With Acute Cardiorespiratory Failure

Overall, 1 in 3 family caregivers of patients who require intensive care unit (ICU) admission will experience significant posttraumatic stress symptoms (PTSSs), but little is known about how PTSSs evolve over time. Measuring PTSS trajectories could facilitate the development of targeted interventions to improve mental health outcomes for family caregivers of critically ill patients. To measure 6-month PTSS trajectories among caregivers of patients with acute cardiorespiratory failure. This prospective cohort study was conducted in the medical ICU of a large academic medical center among adult patients requiring (1) vasopressors for shock, (2) high-flow nasal cannula, (3) noninvasive positive pressure ventilation, or (4) invasive mechanical ventilation. Each patient was enrolled along with their primary caregiver, ie, the unpaid individual who provided the most physical, emotional, or financial support prior to ICU admission. Family caregiver PTSSs were assessed using the Impact of Events Scale-Revised within 48 hours of ICU admission, following ICU discharge, and 3 and 6 months after enrollment. Latent class growth analysis was used to measure PTSS trajectories. Preselected patient and caregiver characteristics measured at ICU admission were analyzed for association with trajectory membership. Six-month patient and caregiver outcomes were analyzed by caregiver trajectory. Overall, 95 family caregivers were enrolled and provided baseline data; mean (SD) age was 54.2 (13.6) years, 72 (76%) were women, 22 (23%) were Black individuals, and 70 (74%) were White individuals. Three trajectories were identified: persistently low (51 caregivers [54%]), resolving (29 [31%]), and chronic (15 [16%]). Low caregiver resilience, prior caregiver trauma, high patient severity of illness, and good patient premorbid functional status were associated with the chronic trajectory. Caregivers with the chronic PTSS trajectory had worse 6-month health-related quality of life (mean [SD] total 36-item Short Form Survey score, persistently low trajectory: 104.7 [11.3]; resolving trajectory: 101.7 [10.4]; chronic trajectory: 84.0 [14.4]; P < .001) and reduced effectiveness at work (mean [SD] perceived effectiveness at work score, persistently low trajectory: 86.0 [24.2]; resolving trajectory: 59.1 [32.7]; chronic trajectory: 72.3 [18.4]; P = .009). In this study, 3 distinct PTSS trajectories among ICU family caregivers were observed, with 16% of caregivers experiencing chronic PTSSs over the subsequent 6 months. Family caregivers with persistent PTSS had lower resilience, prior trauma, higher patient severity of illness, and higher baseline patient functional status compared with family caregivers with persistently low PTSS, with adverse effects on quality of life and work. Identifying these caregivers is an essential first step to develop interventions tailored to those with the greatest need for support.

Trajectories of complex posttraumatic stress symptoms among Chinese college students with childhood adversities: The role of self-compassion

BackgroundComplex posttraumatic stress disorder (CPTSD) is associated with severe impairments in psychosocial functions, but related longitudinal research is limited. To promote the mental health of college students with childhood adversities, it is imperative to investigate the development of CPTSD symptoms and the predictive factors. ObjectivesThe study aimed to examine the latent trajectories of CPTSD symptoms among college students with childhood adversities and to identify the role of self-compassion in differentiating potential trajectories. MethodsA total of 294 college students with childhood adversities completed self-report questionnaires on demographic backgrounds, childhood adversities, CPTSD symptoms, and self-compassion three times with an interval of three months. Latent class growth analysis was used to determine the trajectories of CPTSD symptoms. Multinomial logistic regression was performed to examine the association between self-compassion and trajectories subgroups while adjusting for demographic variables. ResultsThree heterogeneous groups of CPTSD symptoms among college students with childhood adversities were identified: the low-symptoms group (n = 123, 41.8 %), the moderate-symptoms group (n = 108, 36.7 %), and the high-risk group (n = 63, 21.4 %). Multinomial logistic regression showed that, after adjusting for demographic variables, students with higher levels of self-compassion were less likely to belong to the moderate-symptoms and high-risk group in comparison to the low-symptoms group. ConclusionsThe results suggest the trajectories of CPTSD symptoms of college students with childhood adversities were heterogeneous. Self-compassion was a protective factor against the development of CPTSD symptoms. The present study provided insights into the mental health promotion for individuals with adversities.

Associations of polygenic risk scores with posttraumatic stress symptom trajectories following combat deployment.

Identification of genetic risk factors may inform the prevention and treatment of posttraumatic stress disorder (PTSD). This study evaluates the associations of polygenic risk scores (PRS) with patterns of posttraumatic stress symptoms following combat deployment. US Army soldiers of European ancestry (n = 4900) provided genomic data and ratings of posttraumatic stress symptoms before and after deployment to Afghanistan in 2012. Latent growth mixture modeling was used to model posttraumatic stress symptom trajectories among participants who provided post-deployment data (n = 4353). Multinomial logistic regression models tested independent associations between trajectory membership and PRS for PTSD, major depressive disorder (MDD), schizophrenia, neuroticism, alcohol use disorder, and suicide attempt, controlling for age, sex, ancestry, and exposure to potentially traumatic events, and weighted to account for uncertainty in trajectory classification and missing data. Participants were classified into low-severity (77.2%), increasing-severity (10.5%), decreasing-severity (8.0%), and high-severity (4.3%) posttraumatic stress symptom trajectories. Standardized PTSD-PRS and MDD-PRS were associated with greater odds of membership in the high-severity v. low-severity trajectory [adjusted odds ratios and 95% confidence intervals, 1.23 (1.06-1.43) and 1.18 (1.02-1.37), respectively] and the increasing-severity v. low-severity trajectory [1.12 (1.01-1.25) and 1.16 (1.04-1.28), respectively]. Additionally, MDD-PRS was associated with greater odds of membership in the decreasing-severity v. low-severity trajectory [1.16 (1.03-1.31)]. No other associations were statistically significant. Higher polygenic risk for PTSD or MDD is associated with more severe posttraumatic stress symptom trajectories following combat deployment. PRS may help stratify at-risk individuals, enabling more precise targeting of treatment and prevention programs.

Trajectories of Posttraumatic Stress Symptoms Among Young Adults Exposed to a Typhoon: A Three-Wave Longitudinal Study.

Objective: We used a latent class growth model to identify distinct PTSS trajectories and correlates of these trajectories among young adults who experienced Typhoon Hato, the strongest storm to strike China in the last 50years. Methods: A longitudinal survey (three-waves) was conducted to explore the mental health status and its correlates among young adults exposed to the typhoon. Data from 362 participants were analyzed via a latent class growth model and multinomial logistic regression. Results: Three distinct classes of PTSS trajectories were identified, including: "resilience" (86.46%), "recovery" (9.12%), and "deterioration" (4.42%). The higher levels of direct typhoon exposure, media use, and posttraumatic growth significantly predicted the higher likelihood of participants being in the "recovery'' class. In addition, more social support significantly predicted the higher possibility of being in the "resilience" class. Finally, more severe depressive and anxiety symptoms significantly predicted the higher likelihood of being in the "deterioration" class. Conclusion: Further research should develop interventions to enhance protective factors (e.g., posttraumatic growth, media use), decrease risk factors (e.g., depressive and anxiety symptoms), and thereby prevent PTSS.

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.

Post-Traumatic Stress Symptoms in Adolescent Hodgkin Lymphoma Survivors: A Report from Children's Oncology Group AHOD0031.

Purpose: The intrusive thoughts of cancer diagnosis, treatments, re-experiencing, and avoidance associated with post-traumatic stress symptoms (PTSS) can negatively affect Hodgkin lymphoma (HL) survivors. This study investigates the associations between experiences and beliefs and PTSS among adolescent survivors of intermediate-risk HL treated on the Children's Oncology Group (COG) AHOD0031 study. Methods: COG AHOD0031 participants completed self-report surveys at end of therapy concerning post-treatment medical conditions, activity limitations, fatigue, future concerns, exercise, and PTSS. Results: One thousand one hundred ten of 1721 participants in AHOD0031 completed the first survey at a median of 6.7 months post-diagnosis (interquartile range: 5.3-11.5 months), and of these, 736 (66.3%) completed a second survey at a median of 12.4 (10.1-17.6) months following the first. The mean PTSS score (ranging from 0 to 20) was 5.5 (standard deviation [SD] = 5.1) on survey 1 and 4.4 (SD = 4.8) on survey 2. Increased fatigue (odds ratio [OR] = 1.14, p < 0.01), concerns for the future (OR = 1.13, p < 0.01), activity limitations (OR = 1.05, p < 0.01), and relapse history (OR = 2.18, p < 0.05) were associated with higher PTSS scores in the initial survey. Increased fatigue (OR = 1.16, p < 0.01), concerns for the future (OR = 1.14, p < 0.01), activity limitations (OR = 1.05, p < 0.05), and higher PTSS scores on the first survey (OR = 1.19, p < 0.01) were associated with higher PTSS scores in the subsequent survey. Longer time since diagnosis (OR = 0.85, p < 0.05; OR = 0.84, p < 0.05) was associated with lower PTSS scores on both surveys. Conclusions: Based on our findings, future research should examine the onset and trajectory of PTSS among HL survivors, focusing on early recognition and intervention to improve quality of life.

Risk and Resilience in Trajectories of Post-Traumatic Stress Symptoms among First Responders after the 2011 Great East Japan Earthquake: a 7-year prospective cohort study

IntroductionFirst responders to disasters are at risk of developing post-traumatic stress disorder (PTSD). The trajectories of post-traumatic stress symptom severity differ among individuals, even if they are exposed to similar events. These trajectories have not yet been reported in non-Western first responders.ObjectivesWe aimed to explore post-traumatic stress symptom severity trajectories and their risk factors in first responders to the 2011 Great East Japan Earthquake (GEJE)— a historically large earthquake that resulted in a tsunami and a nuclear disaster.Methods56 388 Japan Ground Self-Defense Force (JGSDF) personnel dispatched to the GEJE were enrolled in this seven-year longitudinal cohort study. PTSD symptom severity was measured using the Impact of Event Scale-Revised (IES-R). Trajectories were identified using latent growth mixture models (LGMM). Nine potential risk factors for the symptom severity trajectories were analyzed using multinomial logistic regression.ResultsFive symptom severity trajectories were identified: “resilient” (54.7%), “recovery” (24.5%), “incomplete recovery” (10.7%), “late-onset” (5.7%), and “chronic” (4.3%). The main risk factors for the four non-resilient trajectories were older age, personal disaster experiences, and working conditions. These working conditions included duties involving body recovery or radiation exposure risk, longer deployment length, later or no post-deployment leave, and longer post-deployment overtime.ConclusionsThe majority of first responders to GEJE were resilient and developed few or no PTSD symptoms. A substantial minority experienced late-onset and chronic symptom severity trajectories. The identified risk factors can inform policies for prevention, early detection, and intervention in individuals at risk of developing symptomatic trajectories.DisclosureNo significant relationships.

Understanding posttraumatic stress trajectories in adolescent females: A strength-based machine learning approach examining risk and protective factors including online behaviors.

Heterogeneity in the course of posttraumatic stress symptoms (PTSS) following a major life trauma such as childhood sexual abuse (CSA) can be attributed to numerous contextual factors, psychosocial risk, and family/peer support. The present study investigates a comprehensive set of baseline psychosocial risk and protective factors including online behaviors predicting empirically derived PTSS trajectories over time. Females aged 12-16 years (N = 440); 156 with substantiated CSA; 284 matched comparisons with various self-reported potentially traumatic events (PTEs) were assessed at baseline and then annually for 2 subsequent years. Latent growth mixture modeling (LGMM) was used to derive PTSS trajectories, and least absolute shrinkage and selection operator (LASSO) logistic regression was used to investigate psychosocial predictors including online behaviors of trajectories. LGMM revealed four PTSS trajectories: resilient (52.1%), emerging (9.3%), recovering (19.3%), and chronic (19.4%). Of the 23 predictors considered, nine were retained in the LASSO model discriminating resilient versus chronic trajectories including the absence of CSA and other PTEs, low incidences of exposure to sexual content online, minority ethnicity status, and the presence of additional psychosocial protective factors. Results provide insights into possible intervention targets to promote resilience in adolescence following PTEs.

Posttraumatic stress and COVID-19-related stressors: a prospective observational study

ABSTRACT Background The COVID-19 pandemic may trigger posttraumatic stress symptoms (PTSS) due to its threat to health, well-being, and survival. Objectives We sought to assess levels of change in PTSS at three waves during the COVID-19 pandemic. Our second objective was to examine the role of four objective and subjective predictors salient to COVID-19-loss of resources, sense of loneliness, perceived COVID-19 threat, and uncertainty stress-on the trajectory of PTSS. Methods The study consisted of three waves, a month apart, between June and August 2020, with 903, 718, and 684 participants in each wave, respectively. Results At T0, participants had a medium level of PTSS (M = 2.07, SD = 0.89), which increased at T1 (M = 2.46, SD = 0.97) and decreased at T2 (M = 2.24, SD = 0.93). Linear mixed-effects modeling showed that loss of resources, sense of loneliness, perceived COVID-19 threat, and uncertainty stress were significant predictors of PTSS over the three time-points. Significant interactions between these predictors (except sense of loneliness) and time were found: At higher levels of resource loss, uncertainty stress, and COVID-19 threat, there was a steeper increase in PTSS from baseline to 1 month. Conclusions The four predictors of PTSS should be addressed via strengthening resilience of individuals and communities.

Trajectories of resilience and posttraumatic stress in childhood cancer: Consistency of child and parent outcomes.

Childhood cancer represents a potentially traumatic experience for both patients and caregivers. We examined trajectories of posttraumatic stress symptoms (PTSS) across a 5-year period in children with a history of cancer and their parents/caregivers. Medical, demographic, and dispositional variables were examined as predictors of PTSS trajectories. Using a longitudinal design, children with cancer history (n = 254, age 8-17 years at baseline) and one parent or caregiver (n = 255) completed measures of PTSS at baseline, and 1-, 3-, and 5-years poststudy entry. Children and caregivers completed dispositional measures including optimism, positive or negative affect, and Five-Factor Inventories. Latent class growth analysis (LCGA) was used to identify latent trajectories of PTSS, and univariate logistic regression models were conducted to predict LCGA class membership from medical, demographic, and disposition factors Results: Very similar trajectories were observed in children and caregivers, with two-class solutions providing the best fit: a "resilient" class, with low PTSS at baseline, which declined significantly over time (83.5% in children; 71.5% in parents), and an "elevated PTSS" class, which was moderately high at baseline and increased significantly over time. There was a small, but significant relationship between child and caregiver trajectories. Latent trajectories observed in children and parents were more strongly associated with dispositional variables than medical factors. Resilience, depicted by low PTSS, is by far the most common outcome observed in both children and caregivers. However, the smaller subset with elevated PTSS do not show recovery over time, and are identified as a group in need of targeted interventions.

Traumatic events, daily stressors and posttraumatic stress in unaccompanied young refugees during their flight: a longitudinal cross-country study

BackgroundUnaccompanied young refugees constitute an especially vulnerable population, reporting high rates of trauma and mental health problems. There is a significant gap in the literature on trauma and posttraumatic stress symptoms (PTSS) in unaccompanied young refugees who are still on the move and live in precarious circumstances such as refugee camps. This study therefore aimed to contribute to this gap by investigating pre- and peri-migration (potentially) traumatic experiences of unaccompanied young refugees; longitudinal trajectories of trauma, daily stressors and PTSS; and the impact of gender, trauma, and daily stressors on PTSS over time.MethodsThis longitudinal, mixed-method, and multi-country study was conducted in various settings (e.g. refugee camps, reception centers) across nine European countries. A heterogeneous sample of N = 187 unaccompanied young refugees (78.4% male) from 29 different countries was assessed via interviews at 3 time-points during a period of 27 months. Data was analyzed via growth curve modelling.ResultsPrevalence rates of (potentially) traumatic experiences ranged from 29.5 to 91.9%. Peri-migration traumatization remained stable over time (b = − 0.02; p = 0.371), but the number of reported daily stressors (b = − 0.24; p = 0.001) and PTSS scores significantly decreased over time (b = − 0.98; p = 0.004). Females reported higher PTSS compared with males at baseline (p = 0.002), but gender did not influence the longitudinal trajectory of PTSS. The pre-migration trauma load and daily stressors at baseline did not have a significant effect on PTSS at baseline or on the longitudinal trajectory.ConclusionsThis is the first study to document not only the high numbers of traumatic events for unaccompanied young refugees pre- and peri- migration, but also the continued traumatization during flight, as well as high rates of daily stressors and PTSS. Humanitarian and political assistance is urgently needed to curb the often life-threatening conditions unaccompanied young refugees face during migration.

Trajectory of post-traumatic stress and depression among children and adolescents following single-incident trauma

ABSTRACT Objective Post-traumatic stress disorder and depression have high comorbidity. Understanding their relationship is of clinical and theoretical importance. A comprehensive way to understand post-trauma psychopathology is through symptom trajectories. This study aims to look at the developmental courses of PTSD and depression symptoms and their interrelationship in the initial months post-trauma in children and adolescents. Methods Two-hundred-and-seventeen children and adolescents aged between eight and 17 exposed to single-event trauma were included in the study. Post-traumatic stress symptoms (PTSS) and depression symptoms were measured at 2 weeks, 2 months and 9 months, with further psychological variables measured at the 2-week assessment. Group-based trajectory modelling (GBTM) was applied to estimate the latent developmental clusters of the two outcomes. Logistic regression was used to identify predictors associated with high symptom groups. Results The GBTM yielded a three-group model for PTSS and a three-group model for depression. PTSS trajectories showed symptoms reduced to a non-clinical level by 9 months for all participants (if they were not already in the non-clinical range): participants were observed to be resilient (42.4%) or recovered within 2 months (35.6%), while 21.9% experienced high level PTSS but recovered by 9 months post-trauma. The depression symptom trajectories predicted a chronic non-recovery group (20.1%) and two mild symptom groups (45.9%, 34.0%). Further analysis showed high synchronicity between PTSS and depression groups. Peri-event panic, negative appraisals, rumination and thought suppression at 2 weeks predicted slow recovery from PTSS. Pre-trauma wellbeing, post-trauma anxiety and negative appraisals predicted chronic depression. Conclusions Post-trauma depression was more persistent than PTSS at 9 months in the sampled population. Cognitive appraisal was the shared risk factor to high symptom groups of both PTSS and depression.

Risk and resilience in trajectories of post-traumatic stress symptoms among first responders after the 2011 Great East Japan Earthquake: 7-year prospective cohort study.

First responders to disasters are at risk of developing post-traumatic stress disorder (PTSD). The trajectories of post-traumatic stress symptom severity differ among individuals, even if they are exposed to similar events. These trajectories have not yet been reported in non-Western first responders. We aimed to explore post-traumatic stress symptom severity trajectories and their risk factors in first responders to the 2011 Great East Japan Earthquake (GEJE) - a historically large earthquake that resulted in a tsunami and a nuclear disaster. A total of 55 632 Japan Ground Self-Defense Force (JGSDF) personnel dispatched to the GEJE were enrolled in this 7-year longitudinal cohort study. PTSD symptom severity was measured using the Impact of Event Scale-Revised. Trajectories were identified using latent growth mixture models (LGMM). Nine potential risk factors for the symptom severity trajectories were analysed using multinomial logistic regression. Five symptom severity trajectories were identified: 'resilient' (54.8%), 'recovery' (24.6%), 'incomplete recovery' (10.7%), 'late-onset' (5.7%), and 'chronic' (4.3%). The main risk factors for the four non-resilient trajectories were older age, personal disaster experiences and working conditions. These working conditions included duties involving body recovery or radiation exposure risk, longer deployment length, later or no post-deployment leave and longer post-deployment overtime. The majority of first responders to GEJE were resilient and developed few or no PTSD symptoms. A substantial minority experienced late-onset and chronic symptom severity trajectories. The identified risk factors can inform policies for prevention, early detection and intervention in individuals at risk of developing symptomatic trajectories.
