RESUMO

Background: Improving children's access to mental health services need more innovative solutions, especially in low- and middle-income countries. School-based psychosocial interventions delivered by lay counselors may be an efficient way to improve children's access to mental health services. But few studies were conducted to examine the effectiveness of these interventions. Therefore, this study is to evaluate the effectiveness of trauma-focused cognitive behavioral therapy (TF-CBT) in a group format delivered by lay counselors to children with trauma-related symptoms in China. Methods: A total of 234 children (aged 9-12 years) with full or subthreshold posttraumatic stress disorder (PTSD) were randomly assigned to group-based TF-CBT or treatment as usual (TAU). In the intervention group, 118 children received 10-12 sessions of group-based TF-CBT delivered by lay counselors for 9 consecutive weeks. In the TAU group, 116 children received the usual school services provided by psychology teachers. The primary outcome was the reduction in PTSD severity, which was assessed with the UCLA PTSD reaction index for DSM-5 (PTSD-RI-5). The secondary outcomes included the reduction in PTSD severity and the remission of PTSD, both of which were measured with the PTSD checklist-5 (PCL-5). Secondary outcomes also included the reduction in depression severity and the reduction in generalized anxiety severity. Blinded assessments were collected at baseline, posttreatment (primary endpoint), and 3-month follow-up. This trial is registered with Chinese Clinical Trial Registry, ChiCTR1900027131. Findings: At posttreatment, the intervention group scored significantly lower than the TAU group on PTSD-RI-5 PTSD (30.98 vs. 39.22; adjusted mean difference [AMD], -7.35; 95% CI, -11.66 to -3.04), PCL-5 PTSD (28.78 vs. 38.04; AMD, -8.49; 95% CI, -13.23 to -3.75), depression (5.52 vs. 7.96; AMD, -1.63; 95% CI, -2.50 to -0.76), and generalized anxiety (7.23 vs. 8.64; AMD, -1.21; 95% CI, -2.20 to -0.23). The remission of PCL-5 PTSD was also significantly higher in the intervention group (42.86% vs. 13.54%, χ 2  = 13.10, P < 0.001). These two groups showed a similar level of symptoms at the 3-month follow-up. Interpretation: The group-based TF-CBT can significantly alleviate PTSD, depression, and generalized anxiety right after treatment in Chinese children who suffer from different types of trauma. But the long-term effects of this intervention need to be further tested. This intervention can be delivered by trained lay counselors in low- and middle-income countries. Funding: None.

RESUMO

BACKGROUND: Pediatric posttraumatic stress disorder (pPTSD) is more than three times as likely to develop in trauma-exposed female youth than males. Despite the staggering sex differences in the prevalence rates of pPTSD and symptom expression, relatively little is known about the underlying biomarkers of these sex-based variations in pPTSD as compared to typically development. METHODS: The Youth PTSD study recruited 97 youth, ages of 7 and 18, to undergo comprehensive clinical assessments and T1-weighted MRI to evaluate the extent to which sex can explain PTSD-related variations in brain structure. Whole-brain VBM as well as whole-brain estimates of cortical thickness and surface area were analyzed to identify group-by-sex interactions. Finally, we tested whether current or future symptom severity was predictive of regions exhibiting sex-based variations. RESULTS: Clinically, females with PTSD were significantly more likely to report exposure to and higher severity of interpersonal violence and symptoms of hyperarousal. Sex and PTSD status were predictive of gray matter across the lateral prefrontal cortex (PFC), including the ventrolateral PFC and frontal pole, where increased volume and surface area was found in PTSD females as compared to PTSD males. Interestingly, the ventrolateral prefrontal cortex and frontal pole were negatively predictive of symptoms 1 year later in only males with PTSD. CONCLUSIONS: Together, these results establish that youth with PTSD exhibit sex-based variations in clinical and trauma characteristics and prefrontal cortical structure relative to normative development. This work demonstrates the importance of examining the role that sex may play in the behavioral and neurobiological presentation of pPTSD.

RESUMO

Service members and veterans can be exposed to potentially traumatic and morally injurious experiences (PMIEs) including participating in, witnessing, or failing to prevent an act(s) that transgresses their core beliefs. Violation of one's deeply held morals and values can be profoundly distressing and shatter one's sense of self at the deepest level. Relationships with self, others, the world, and for some, the Sacred, can also be fractured. Post-Traumatic Stress Disorder (PTSD) and/or Moral Injury (MI) can result. Left unresolved, MI can leave individuals struggling with guilt, shame, cognitive dissonance, and negative self-attributions. A holistic approach that addresses the psychological and spiritual harm associated with MI is warranted. We wonder if forgiveness can help individuals struggling with MI to address the harm caused by actions or inactions, release negative emotions, and mend relationships. Commonly used by Spiritual/Religious (S/R) Leaders, forgiveness practices are increasingly being explored by Mental Health Professionals as a complement to evidence-based treatment approaches. This article provides case examples that illustrate the use of forgiveness practices that promote recovery and identifies programs used in clinical practice that incorporate forgiveness. Research is yet needed to better understand the importance of forgiveness in the treatment and healing of PTSD and/or MI. This requires an interdisciplinary discourse between Mental Health Professionals and S/R Leaders working in the field of MI. Such engagement and integrated use of forgiveness practices may yield improved outcomes not only for service members and veterans, but for all those struggling as a result of PTSD and/or MI.

RESUMO

Telomeres are short tandem repeats of "TTAGGG" that protect the chromosome ends from deterioration or fusion of chromosomes. Their repeat length shortens with cell division acting as a biomarker of cellular aging. Traumatic stress events during adulthood or childhood have been associated with posttraumatic stress disorder (PTSD) and short leukocyte telomere length (LTL). This study investigated whether LTL was associated with PTSD in a Brazilian sample of sexually assaulted civilian women at two time points: baseline and 1-year follow-up. At baseline, we assessed 64 women with PTSD following sexual assault (cases) and 60 women with no previous history of sexual trauma or mental disorders (healthy controls - HC). At follow-up visit, 13 persistent PTSD cases, 11 HCs, and 11 PTSD remitters patients were evaluated. PTSD diagnosis and severity were assessed using Mini International Neuropsychiatric Interview (Diagnostic and Statistical Manual of Mental Disorders III/IV criteria) and Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), respectively. LTL was measured using multiplex real-time polymerase chain reaction (PCR). In the baseline analysis, we observed that LTL was associated with re-experiencing symptoms (B = -0.16; confidence interval (CI) 95% = -0.027--0.005; Bonferroni-adjusted p-value = 0.02), but no association was observed between other PTSD symptoms and LTL. In the longitudinal analysis, telomere shortening was no longer observed in patients with PTSD and PTSD remitters. In conclusion, our findings indicate that shorter baseline LTL is associated with early stage of PTSD re-experiencing symptoms in recently sexually assaulted women.

RESUMO

Prolonged Exposure (PE) therapy is one of the most efficacious, evidence-based treatments for posttraumatic stress disorder (PTSD). A key component of PE involves in vivo exposures (IVEs) during which patients approach situations or activities in "real life" that are safe but avoided because they elicit a fear response. Despite their critical role in treatment, little research has focused on IVEs. This gap in knowledge is primarily due to the fact that IVEs are typically conducted by patients in between therapy sessions, leaving clinicians reliant upon patient self-report. This approach has numerous shortcomings, which the current study addresses by leveraging technology to develop an innovative device that allows for physiological, biomarker-driven, therapist-guided IVEs. The new system enables clinicians to virtually accompany patients during IVEs and provides real-time physiological (heart rate, skin conductance) and self-report (subjective units of distress) data that clinicians can use to modify the exposure and optimize therapeutic value. This Small Business Innovation Research (SBIR) Phase I project aims to: (1) integrate physiological sensors and live audio/visual streaming into a system for clinicians to guide patients during IVEs; (2) determine feasibility and acceptability of the system; and (3) conduct a pilot randomized clinical trial among veterans with PTSD (N = 40) to evaluate the preliminary efficacy of the system in reducing PTSD symptoms during PE. This paper describes the rationale, design, and methodology of the Phase I project. The findings from this study have the potential to innovate clinical practice, advance the science of exposure therapy, and improve clinical outcomes.

RESUMO

Therapeutic interventions for disorders of fear and anxiety rely on behavioral approaches that reduce pathological fear memories. For example, learning that threat-predictive stimuli are no longer associated with aversive outcomes is central to the extinction of conditioned fear responses. Unfortunately, fear memories are durable, long-lasting, and resistant to extinction, particularly under high levels of stress. This is illustrated by the "immediate extinction deficit," which is characterized by a poor long-term reduction of conditioned fear when extinction procedures are attempted within hours of fear conditioning. Here, I will review recent work that has provided new insight into the neural mechanisms underlying resistance to fear extinction. Emerging studies reveal that locus coeruleus norepinephrine modulates amygdala-prefrontal cortical circuits that are critical for extinction learning. These data suggest that stress-induced activation of brain neuromodulatory systems biases fear memory at the expense of extinction learning. Behavioral and pharmacological strategies to reduce stress in patients undergoing exposure therapy might improve therapeutic outcomes.

RESUMO

Substance use disorders (SUD) may emerge from an individual's attempt to limit negative affective states and symptoms linked to stress. Indeed, SUD is highly comorbid with chronic stress, traumatic stress, or post-traumatic stress disorder (PTSD), and treatments approved for each pathology individually often failed to have a therapeutic efficiency in such comorbid patients. The kappa-opioid receptor (KOR) and its endogenous ligand dynorphin (DYN), seem to play a key role in the occurrence of this comorbidity. The DYN/KOR function is increased either in traumatic stress or during drug use, dependence acquisition and DYN is released during stress. The behavioural effects of stress related to the DYN/KOR system include anxiety, dissociative and depressive symptoms, as well as increased conditioned fear response. Furthermore, the DYN/KOR system is implicated in negative reinforcement after the euphoric effects of a drug of abuse ends. During chronic drug consumption DYN/KOR functions increase and facilitate tolerance and dependence. The drug-seeking behaviour induced by KOR activation can be retrieved either during the development of an addictive behaviour, or during relapse after withdrawal. DYN is known to be one of the most powerful negative modulators of dopamine signalling, notably in brain structures implicated in both reward and fear circuitries. KOR are also acting as inhibitory heteroreceptors on serotonin neurons. Moreover, the DYN/KOR system cross-regulate with corticotropin-releasing factor in the brain. The sexual dimorphism of the DYN/KOR system could be the cause of the gender differences observed in patients with SUD or/and traumatic stress-related pathologies. This review underlies experimental and clinical results emphasizing the DYN/KOR system as common mechanisms shared by SUD or/and traumatic stress-related pathologies, and suggests KOR antagonist as a new pharmacological strategy to treat this comorbidity.

RESUMO

BACKGROUNDS: Refugees and asylum-seekers are at heightened risk for developing psychological symptoms following exposure to trauma and displacement. Despite this, relatively little is known about the cognitive mechanisms that underlie common mental disorders in refugees. METHODS: In this study, we investigated the associations between self-efficacy, beliefs about others (relating to benevolence and trust) and psychological and social outcomes in 1079 refugees from Arabic, Farsi, Tamil or English-speaking backgrounds who were residing in Australia. Participants completed an online survey assessing exposure to potentially traumatic events (PTEs), at baseline (T1), and self-efficacy, beliefs about others, PTSD symptoms, depression symptoms, anger and social engagement at baseline (T1) and six months later (T2). RESULTS: A path analysis revealed that greater PTE exposure was associated with lower self-efficacy and lower positive beliefs about others at T1. Self-efficacy at T1 was negatively associated with depression and anger at T2, while positive beliefs about others at T1 were positively associated with social engagement and greater depression symptoms at T2. LIMITATIONS: Limitations of this study included the fact that the study sample was not necessarily representative of the broader refugee population, and in particular may have overrepresented those with higher education levels. CONCLUSIONS: Findings point to the critical role that cognitive variables play in the maintenance of psychological symptoms in forcibly displaced persons, and highlight the importance of targeting these in psychological interventions to promote positive posttraumatic mental health.

RESUMO

Although many children experience trauma, few receive diagnoses and subsequent care despite experiencing trauma-related sequelae. At age nine (M = 9.11), children (N = 62; female = 46.4%) who predominantly identified as Black (78.7%) were enrolled in this first study examining how skin conductance as captured by mobile technology, eSense, related to children's traumatic experiences and trauma-related symptoms. Skin conductance measures were associated with degree of trauma exposure and PTSD hyperarousal symptoms. These findings suggest that physiological responses in addition to self-report measures may be easily used to assess children's trauma exposure and symptoms. Given eSense's ease-of-use, this technology could assist clinics and research institutions assess children's trauma-related needs.

RESUMO

Individual behaviors are critical for preventing the spread of coronavirus disease 2019 (COVID-19) infection. Given that both protective and risky behaviors influence risk of infection, it is critical that we understand how such behaviors cluster together and in whom. Using a data-driven approach, we identified clusters of COVID-19-related protective and risky behaviors and examined associations with socio-demographic, pandemic, and mental health factors. Data came from a cross-sectional online U.S. nationwide study of 832 adults with high levels of pre-pandemic trauma. Latent class analysis was performed with ten protective (e.g., washing hands, wearing masks) and eight risky (e.g., attending indoor restaurants, taking a flight) behaviors for COVID-19. Then, we examined distributions of socio-demographic and pandemic factors across behavior classes using ANOVA or Chi-square tests, and associations between mental health factors (depressive, anxiety, posttraumatic stress symptoms) and behavior classes using multinomial logistic regression. We identified four classes, including three classes with relatively low risky but high (28.8%), moderate (33.5%) and minimal (25.5%) protective behaviors and one high risky behaviors class with associated moderate protective behaviors (12.1%). Age, sexual orientation, political preference, and most pandemic factors differed significantly across behavior classes. Anxiety and posttraumatic stress symptoms, but not depression, were higher in the High Risk, but also Highly and Moderately Protective classes, relative to Minimally Protective. Prevention and intervention efforts should examine constellations of protective and risky behaviors to comprehensively understand risk, and consider current anxiety and posttraumatic stress symptoms as potential risk indicators.

RESUMO

This study aimed to find the prevalence of stress, anxiety, depression, and PTSD; differences according to demographic variables; and predictors of mental health problems during the second wave of the coronavirus disease (COVID-19) pandemic in Turkey. Differences in exposure to COVID-19 during the first and second waves of the pandemic among students were compared. A total of 754 students from seven universities in different parts of Turkey participated in the survey between November and December 2020. Perceived Stress Scale (PSS-10), Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9), Checklist-Civilian Version (PCL-C) scale measuring posttraumatic stress disorder (PTSD), and Satisfaction with Life Scale (SWLS) were used to measure the mental well-being of students. Descriptive statistics, one-way ANOVA, correlations, and multinomial logistic regression methods were used to analyze the data. The prevalence of high stress, high generalized anxiety (GAD-7 ≥ 10), high depression symptoms (PHQ-9 ≥ 10), and high PTSD in the total sample were 84.2, 36.2, 55.0, and 61.2%, respectively. High perceived stress, moderate generalized anxiety disorder, mild depression symptoms, high severity PTSD, and moderate satisfaction were found among students in Turkey. Religiosity and spirituality have significant negative correlations with anxiety, depression, and PTSD. Religiosity level, gender, relationship status, year of study, physical activity, symptoms of coronavirus, death of a close relative, job loss, and economic status are significant parameters for predicting psychological problems of students in Turkey.

RESUMO

BACKGROUND: Posttraumatic stress disorder (PTSD) is associated with hyperarousal and stress reactivity, features consistent with behavioral sensitization. In this Phase 1b, parallel-arm, randomized, double-blind, placebo-controlled trial, we tested whether the selective low-trapping N-methyl-D-aspartate receptor (NMDAR) antagonist [Lanicemine (BHV-5500)] blocks expression of behavioral sensitization. METHODS: Twenty-four participants with elevated anxiety potentiated startle (APS) and moderate-to-severe PTSD symptoms received three infusions of lanicemine 1.0 mg/ml (100 mg) or matching placebo (0.9% saline) (1:1 ratio), over a 5-day period. The primary outcome was change in APS from baseline to end of third infusion. We also examined changes in EEG gamma-band oscillatory activity as measures of NMDAR target engagement and explored Clinician-Administered PTSD Scale (CAPS-5) hyperarousal scores. RESULTS: Lanicemine was safe and well-tolerated with no serious adverse events. Using Bayesian statistical inference, the posterior probability that lanicemine outperformed placebo on APS T-score after three infusions was 38%. However, after the first infusion, there was a 90% chance that lanicemine outperformed placebo in attenuating APS T-score by a standardized effect size more than 0.4. CONCLUSION: We demonstrated successful occupancy of lanicemine on NMDAR using gamma-band EEG and effects on hyperarousal symptoms (Cohen's d = 0.75). While lanicemine strongly attenuated APS following a single infusion, differential changes from placebo after three infusions was likely obscured by habituation effects. To our knowledge, this is the first use of APS in the context of an experimental medicine trial of a NMDAR antagonist in PTSD. These findings support selective NMDAR antagonism as a viable pharmacological strategy for salient aspects of PTSD.

RESUMO

Posttraumatic stress disorder (PTSD) is highly prevalent among veterans. Although there are effective treatment approaches for PTSD, such as Prolonged Exposure (PE) and Cognitive Processing Therapy, many providers trained in these approaches do not use them, or use them without sufficient fidelity, and veterans drop out of these treatments at very high rates. The time intensive nature of these treatments is frequently cited as a barrier to receiving the treatment among veterans and delivering the treatment among providers. According, there is an urgent need to establish more efficient and effective PTSD treatment approaches in order to meet the needs of veterans seeking care. Written exposure therapy (WET) is an efficient, exposure-based treatment, and may represent a plausible alternative treatment option to address PTSD in veterans. Although WET has been found to be effective and non-inferior to more time intensive trauma-focused treatment, it has not yet been investigated with a veteran sample. In an ongoing randomized controlled trial (RCT) we are investigating whether WET is non-inferior in treating PTSD compared with the more time intensive PE. The study sample will include 150 men and women veterans diagnosed with PTSD who are randomly assigned to either WET (n = 75) or PE (n = 75). Participants are assessed prior to treatment and 10-, 20-, and 30-weeks after the first treatment session. The primary outcome is PTSD symptom severity assessed with the Clinician Administered PTSD Scale for DSM-5. Establishing that PTSD can be treated effectively with fewer treatment sessions would represent a significant advance in improving access to evidence-based care for veterans with PTSD.

RESUMO

Posttraumatic headache (PTH) is a common debilitating condition arising from head injury and is highly prevalent among military service members and veterans with traumatic brain injury (TBI). Diagnosis and treatment for PTH is still evolving, and surprisingly little is known about the putative mechanisms that drive these headaches. This manuscript describes the design of a randomized clinical trial of two nonpharmacological (i.e., behavioral) interventions for posttraumatic headache. Design of this trial required careful consideration of PTH diagnosis and inclusion criteria, which was challenging due to the lack of standard clinical characteristics in PTH unique from other types of headaches. The treatments under study differed in clinical focus and dose (i.e., number of treatment sessions), but the trial was designed to balance the treatments as well as possible. Finally, while the primary endpoints for pain research can vary from assessments of pain intensity to objective and subjective functional measures, this trial of PTH interventions chose carefully to establish clinically relevant endpoints and to maximize the opportunity to detect significant differences between groups with two primary outcomes. All these issues are discussed in this manuscript.

RESUMO

Brain perfusion single photon emission computed tomography (SPECT) scans were initially developed in 1970's. A key radiopharmaceutical, hexamethylpropyleneamine oxime (HMPAO), was originally approved in 1988, but was unstable. As a result, the quality of SPECT images varied greatly based on technique until 1993, when a method of stabilizing HMPAO was developed. In addition, most SPECT perfusion studies pre-1996 were performed on single-head gamma cameras. In 1996, the Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology (TTASAAN) issued a report regarding the use of SPECT in the evaluation of neurological disorders. Although the TTASAAN report was published in January 1996, it was approved for publication in October 1994. Consequently, the reported brain SPECT studies relied upon to derive the conclusions of the TTASAAN report largely pre-date the introduction of stabilized HMPAO. While only 12% of the studies on traumatic brain injury (TBI) in the TTASAAN report utilized stable tracers and multi-head cameras, 69 subsequent studies with more than 23,000 subjects describe the utility of perfusion SPECT scans in the evaluation of TBI. Similarly, dementia SPECT imaging has improved. Modern SPECT utilizing multi-headed gamma cameras and quantitative analysis has a sensitivity of 86% and a specificity of 89% for the diagnosis of mild to moderate Alzheimer's disease-comparable to fluorodeoxyglucose positron emission tomography. Advances also have occurred in seizure neuroimaging. Lastly, developments in SPECT imaging of neurotoxicity and neuropsychiatric disorders have been striking. At the 25-year anniversary of the publication of the TTASAAN report, it is time to re-examine the utility of perfusion SPECT brain imaging. Herein, we review studies cited by the TTASAAN report vs. current brain SPECT imaging research literature for the major indications addressed in the report, as well as for emerging indications. In Part II, we elaborate technical aspects of SPECT neuroimaging and discuss scan interpretation for the clinician.

RESUMO

BACKGROUND: In trauma-exposed adults, the relationship between an individual's socioeconomic position (SEP) and post-traumatic stress disorder (PTSD) has been well demonstrated. One potential mechanism by which the stress associated with lower SEPs may impact trauma outcomes is through changes in neurocognition. In both healthy and clinical samples, area-level factors also appear to be independently related to neurocognition. Far less is known about how neighborhood socioeconomic disadvantage, may impact cognition in traumatically-injured adults. The current study employed hierarchical linear modeling to longitudinally investigate whether neighborhood disadvantage was associated with neurocognitive functioning in five domains: processing speed, sustained attention, controlled attention, cognitive flexibility, and response inhibition. METHODS: One-hundred and ninety-five socioeconomically diverse traumatically-injured subjects (mean age = 32.8, 52.8% female) were recruited from an Emergency Department. Two-weeks, three-months, and six-months post-trauma, participants completed self-report measures and a computerized test battery to evaluate neurocognition. An Area Deprivation Index (ADI) score, a measure of a neighborhood's socioeconomic disadvantage, was derived from each participants' home address. RESULTS: Greater neighborhood disadvantage was significantly related to lower scores in all domains. Results of hierarchical linear models revealed neighborhood disadvantage was significantly associated with processing speed, controlled attention, cognitive flexibility, and response inhibition across time, even after adjusting for individual annual household income, baseline PTSD symptoms, and previous adverse life experiences. This relationship was stable for all domains except sustained attention, which varied across time. CONCLUSION: These findings indicate neighborhood disadvantage contributes uniquely to neurocognitive functioning and, for the majority of domains, these contributions are stable across time. The relationship between area-level variables and cognitive function may underlie individual vulnerability to developing psychiatric disorders. Future work should continue to examine the interaction between socioenvironmental stressors and PTSD symptoms longitudinally.

RESUMO

BACKGROUND: Maltreatment by a primary caregiver is an important risk factor for the development of PTSD symptoms. Whereas meta-analyses indicate that parental emotional abuse is one of the most common forms of maltreatment, the impact of emotional abuse on PTSD symptoms and treatment effectiveness is still unclear, especially in children. OBJECTIVE: We aimed to investigate the impact of parental emotional abuse on PTSD symptom severity and effectiveness of trauma treatment in children and adolescents. METHOD: In an outpatient sample (N = 287, mean age = 15.5 years), emotional abuse, index traumatic event, and PTSD symptoms were assessed at baseline. Thereafter, patients received evidence-based treatment for trauma-related symptoms embedded in a broader (systemic) treatment package. In a subsample (n = 130, mean age = 15.3 years) PTSD symptoms were assessed again 6 and 12 months after baseline. RESULTS: Emotional abuse (rather than any other type of maltreatment) was associated with more severe PTSD symptoms in all symptom clusters. This was independent of whether emotional abuse was reported as index traumatic event or not. Moreover, PTSD symptoms were significantly reduced 6 months after the start of trauma-focused treatment, and emotional abuse was associated with more severe PTSD symptoms over the course of treatment. CONCLUSIONS: These findings underline the detrimental nature of emotional maltreatment in the context of PTSD symptomatology and treatment effectiveness. This calls for routine assessment of parental emotional abuse in the diagnostic phase, even when this is not the reason of referral.

RESUMO

BACKGROUND: The COVID-19 pandemic is the most serious global public health crisis since the 1918 influenza pandemic. This study is the first to assess its mental health impact across the lifespan in the United States in adolescents, adults, and health care workers. METHODS: We recruited 4909 participants through an online survey advertising on Facebook and Instagram to assess exposure to COVID-19 and psychiatric symptoms from April 27 to July 13. We also recruited through the University of Pittsburgh, University of Pittsburgh Medical Center, and other health care systems around Pittsburgh. The primary outcomes were clinically significant depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms, suicidal ideation or behavior, and grief reactions since COVID-19. RESULTS: Adolescents were significantly more likely to report moderate to severe symptoms of depression (55% vs. 29%; χ2 = 122, df = 1; p < .001), anxiety (48% vs. 29%; χ2 = 73; df = 1; p < .001), PTSD (45% vs. 33%; χ2 = 12; df = 1; p < .001), suicidal ideation or behavior (38% vs. 16%; χ2 = 117; df = 1; p < .001), and sleep problems (69% vs. 57%; χ2 = 26; df = 1; p < .001) compared to adults. The rates of intense grief reactions among those who lost someone to COVID-19 was 55%. Loneliness was the most common predictor across outcomes and higher number of hours spent on social media and exposure to media about COVID-19 predicted depression symptoms and suicidal ideation or behavior in adolescents. CONCLUSIONS: The COVID-19 pandemic is associated with increased rates of clinically significant psychiatric symptoms.

RESUMO

In 1948, the state of Israel was created as a homeland for the Jewish people after 2,000 years of persecution and deportations in the diaspora. During the past 72 years, its inhabitants have experienced several wars and numerous terrorist attacks. Therefore, the issue of trauma goes beyond academic study, it is part of daily life. These circumstances have, unfortunately, turned Israel into a natural stress laboratory, which has enabled the systematic research of the biopsychosocial effects of traumatic stress on soldiers and civilians. This article reviews the findings of a series of studies that examine (a) the short- and long-term mental health effects of war on combat veterans; (b) the effects of repeated exposure to war on veterans; (c) trajectories of PTSD; and, specifically, (d) reactivation and (e) delayed-onset PTSD. We present the findings of two decades of systematic trauma research, which have followed the ongoing psychopathological effect of war on veterans. In understanding the ripple effects of trauma, it can be seen that veterans do not leave the events of the war behind once they are home; rather, it is with them wherever they go. Consequently, the trauma has a ripple effect that may carry over to veterans' spouses and offspring. The multiple manifestations and trajectories of both acute and chronic trauma will be presented. Clinical ramifications and implications will also be discussed.
