Abstract
OBJECTIVE Research has cited increased prevalence of mood disorders, anxiety disorders, and exposure to interpersonal violence for Hispanics and non-Hispanic Black adolescents, as well as ethnic differences in externalizing behavior (e.g., substance use, delinquency). The current study combined these areas by examining racial/ethnic differences in mental health correlates of trauma exposure. METHOD Interviews were conducted to assess polyvictimization, posttraumatic stress disorder (PTSD), major depressive disorder (MDD), substance use, and delinquency in a nationally representative sample of adolescents (N = 3,614; 15.4% non-Hispanic Black; 11.3% Hispanic; 64.9% non-Hispanic White). RESULTS Hispanic and non-Hispanic Black adolescents endorsed greater polyvictimization than non-Hispanic Whites; however, differences in MDD and PTSD were only significant when assessed with symptom counts. Non-Hispanic Black adolescents reported the least drug use. Non-Hispanic Black and Hispanic adolescents endorsed more delinquency than non-Hispanic White adolescents. Polyvictimization only accounted for ethnic disparities in delinquency. CONCLUSION Trauma-related disparities may differ across internalizing and externalizing concerns. Subsequent research should continue to examine other factors that may contribute to racial/ethnic differences in trauma sequelae. (PsycINFO Database Record

Abstract
Some adolescents manage to be resilient, whereas others develop posttraumatic stress disorder (PTSD) symptoms after experiencing trauma, but the mechanisms underlying these differences are unclear. Public secondary school students (N = 98) referred for counseling completed questionnaires assessing exposure to stressful events, family communication, and PTSD. Seventy percent of the sample reported PTSD symptoms in the clinical range. Open family communication was negatively associated with female gender, problem family communication (PFC), and PTSD symptom severity. PFC was positively associated with female gender, number of stressful events, and PTSD symptom severity. Family storytelling style had a negative association with age, PFC, and avoidance symptoms. In the full regression model only the number of life events and PFC appeared to have an independent effect on PTSD symptom severity. Results indicate that exposure to stressful life events and poor family communication are associated with increased risk for PTSD symptoms. Findings may be useful in family-focused approaches to treating adolescents with trauma histories and highlighting the importance of PTSD screening in school-based counseling.

The epidemiology of post-traumatic stress disorder in Norway: trauma characteristics and pre-existing psychiatric disorders. Soc Psychiatry Psychiatr Epidemiol 2017; 52:11-19. [PMID: 27757493 PMCID: PMC5226978 DOI: 10.1007/s00127-016-1295-3] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2016] [Accepted: 10/10/2016] [Indexed: 11/22/2022]
Abstract
PURPOSE The prevalence of PTSD differs by gender. Pre-existing psychiatric disorders and different traumas experienced by men and women may explain this. The aims of this study were to assess (1) incidence and prevalence of exposure to traumatic events and PTSD, (2) the effect of pre-existing psychiatric disorders prior to trauma on the risk for PTSD, and (3) the effect the characteristics of trauma have on the risk for PTSD. All stratified by gender. METHOD CIDI was used to obtain diagnoses at the interview stage and retrospectively for the general population N = 1634. RESULTS The incidence for trauma was 466 and 641 per 100,000 PYs for women and men, respectively. The incidence of PTSD was 88 and 31 per 100,000 PYs. Twelve month and lifetime prevalence of PTSD was 1.7 and 4.3 %, respectively, for women, and 1.0 and 1.4 %, respectively, for men. Pre-existing psychiatric disorders were risk factors for PTSD, but only in women. Premeditated traumas were more harmful. CONCLUSION Gender differences were observed regarding traumatic exposure and in the nature of traumas experienced and incidences of PTSD. Men experienced more traumas and less PTSD. Pre-existing psychiatric disorders were found to be risk factors for subsequent PTSD in women. However, while trauma happens to most, it only rarely leads to PTSD, and the most harmful traumas were premeditated ones. Primary prevention of PTSD is thus feasible, although secondary preventive efforts should be gender-specific.

Abstract
Children exposed to multiple sources of violence may become desensitized, increasing the possibility of them imitating the aggressive behaviors they watch and considering such behavior as normal. The purpose of this article is to assess the association between exposure to various types of violence (including war) and desensitization in Lebanese children. A cross-sectional design with 207 school-aged children assessed exposure to violence using three surveys: (a) violence in the media (the Media Preference survey), (b) exposure to violence (the KID-SAVE survey), and (c) desensitization attitudes (the Attitude Toward Violence-Child Version). Children were between 8 and 12 years old, 56% were males, and 70%were from middle socioeconomic status (SES) backgrounds. Seventy-six percent of children reported being exposed to violence, with more exposure in males and in the lower SES group. Impact, however, was greater on girls. The predictors of attitude toward violence were "Frequency" of exposure, "Impact" of exposure, and the amount of violence viewed on television. Children are massively exposed to violence in Lebanon resulting in desensitization, which may habituate them to accept violence as normal and put them at risk for imitating violent behaviors.

Abstract
We measured stress, depression and post-traumatic stress disorder (PTSD) levels of urban Indigenous women living with and without HIV in Ontario, Canada, and identified correlates of depression. We recruited 30 Indigenous women living with HIV and 60 without HIV aged 18 years or older who completed socio-demographic and health questionnaires and validated scales assessing stress, depression and PTSD. Descriptive statistics were conducted to summarize variables and linear regression to identify correlates of depression. 85.6 % of Indigenous women self-identified as First Nation. Co-morbidities other than HIV were self-reported by 82.2 % (n = 74) of the sample. High levels of perceived stress were reported by 57.8 % (n = 52) of the sample and 84.2 % (n = 75) had moderate to high levels of urban stress. High median levels of race-related (51/88, IQR 42-68.5) and parental-related stress (40.5/90, IQR 35-49) scores were reported. 82.2 % (n = 74) reported severe depressive symptoms and 83.2 % (n = 74) severe PTSD. High levels of perceived stress was correlated with high depressive symptoms (estimate 1.28 (95 % CI 0.97-1.58), p < 0.001). Indigenous women living with and without HIV reported elevated levels of stress and physical and mental health concerns. Interventions cutting across diverse health care settings are required for improving and preventing adverse health outcomes.

Abstract
PURPOSE The association between victimisation and adverse health in children is well established but few studies have addressed the effect of victimisation, especially multiple victimisations, in older adolescents and young adults. The aim of this study was to assess self-reported health in young women (15-22 years) victimised to one or more types of violence, compared with non-victimised. METHODS: Young women visiting youth health centres in Sweden answered a questionnaire constructed from standardised instruments addressing violence victimisation (emotional, physical, sexual and family violence), socio-demographics, substance use and physical and mental health. Adjusted odds ratio (AOR) with 95% confidence interval (CI) and attributable risk (AR) were assessed. RESULTS: Of 1051 women (73% of eligible women), 25% were lifetime victims of one type of violence and 31% of two or more types of violence. Sexual-minority young women were more victimised than heterosexual women. Violence victimisation increased the risk for adverse health outcomes, especially evident for those multiply victimised. Victims of two or more types of violence had AOR 11.8 (CI 6.9-20.1) for post-traumatic stress symptoms, 6.3 (CI 3.9-10.2) for anxiety symptoms and 10.8 (CI 5.2-22.5) for suicide ideation. The AR of victimisation accounted for 41% of post-traumatic stress symptoms, 30% of anxiety symptoms and 27% of suicide ideation. Stratified analyses showed that lower economic resources did not influence health negatively for non-victimised, whereas it multiplicatively reinforced ill-health when combined with violence victimisation. CONCLUSION: Violence victimisation, and particularly multiple victimisations, was strongly associated with mental ill-health in young women, especially evident in those with low economic resources.

Abstract
OBJECTIVE Posttraumatic stress disorder (PTSD) is often underdiagnosed and undertreated among adolescents. The objective of this analysis was to describe the prevalence and correlates of symptoms consistent with PTSD among adolescents presenting to an urban emergency department (ED). METHODS A cross-sectional survey of adolescents aged 13-17 years presenting to the ED for any reason was conducted between August 2013 and March 2014. Validated self-report measures were used to measure mental health symptoms, violence exposure and risky behaviors. Multivariate logistic regression analysis was performed to determine adjusted differences in associations between symptoms consistent with PTSD and predicted correlates. RESULTS Of 353 adolescents, 23.2% reported current symptoms consistent with PTSD, 13.9% had moderate or higher depressive symptoms and 11.3% reported past-year suicidal ideation. Adolescents commonly reported physical peer violence (46.5%), cyberbullying (46.7%) and exposure to community violence (58.9%). On multivariate logistic regression, physical peer violence, cyberbullying victimization, exposure to community violence, female gender and alcohol or other drug use positively correlated with symptoms consistent with PTSD. CONCLUSIONS Among adolescents presenting to the ED for any reason, symptoms consistent with PTSD, depressive symptoms, physical peer violence, cyberbullying and community violence exposure are common and interrelated. Greater attention to PTSD, both disorder and symptom levels, and its cooccurring risk factors is needed.

Abstract
BACKGROUND In most countries, socio-demographic factors influence the incidence of burns in children. The aims of this literature review were therefore to identify which of those factors are linked to an increase in the prevalence and identify ways of enhancing burn prevention programmes and preventing practices which play a role in the occurrence of burns in children. METHOD A comprehensive search (no time limit) of primary studies, titles and abstracts was undertaken in the following electronic databases; MEDLINE, CINAHL, ERIC, Cochrane Library, PsychInfo and Google Scholar. RESULTS Socio-demographic factors which were linked to an increased incidence of burns include low household income, living in deprived areas, living in rented accommodation, young mothers, single-parent families and children from ethnic minorities. The level of parental education, parental occupation, and the type and size of accommodation were also cited. CONCLUSION A range of socio-demographic factors result in an increase in the prevalence of burns, and the risk is even greater in children who are exposed to a number of these factors. Such information will be useful for planning prevention strategies and identifying further research questions that need to be answered.

Abstract
Pediatric health care networks serve millions of children each year. Pediatric illness and injury are among the most common potentially emotionally traumatic experiences for children and their families. In addition, millions of children who present for medical care (including well visits) have been exposed to prior traumatic events, such as violence or natural disasters. Given the daily challenges of working in pediatric health care networks, medical professionals and support staff can experience trauma symptoms related to their work. The application of a trauma-informed approach to medical care has the potential to mitigate these negative consequences. Trauma-informed care minimizes the potential for medical care to become traumatic or trigger trauma reactions, addresses distress, provides emotional support for the entire family, encourages positive coping, and provides anticipatory guidance regarding the recovery process. When used in conjunction with family-centered practices, trauma-informed approaches enhance the quality of care for patients and their families and the well-being of medical professionals and support staff. Barriers to routine integration of trauma-informed approaches into pediatric medicine include a lack of available training and unclear best-practice guidelines. This article highlights the importance of implementing a trauma-informed approach and offers a framework for training pediatric health care networks in trauma-informed care practices.

Abstract
Studies have found a stronger association between anger and posttraumatic stress disorder (PTSD) severity in military populations than in nonmilitary populations. Two hypotheses have been proposed to explain this difference: Military populations are more prone to anger than nonmilitary populations, and traumas experienced on deployment create more anger than nondeployment traumas. To examine these hypotheses, we evaluated the association between anger and PTSD severity among never-deployed military service members with nondeployment traumas (n = 226) and deployed service members with deployment traumas (n = 594) using linear regression. We further examined these associations stratified by gender. Bivariate associations between anger and PTSD severity were similar for nondeployment and deployment events; however, gender modified this association. For men, the association for deployment events was stronger than for nondeployment events (β = .18, r = .53 vs. β = .16, r = .37, respectively), whereas the reverse was true for women (deployment: β = .20, r = .42 vs. nondeployment: β = .25, r = .65). Among men, findings supported the hypothesis that deployment traumas produce stronger associations between PTSD and anger and are inconsistent with hypothesized population differences. In women, however, there was not a clear fit with either hypothesis.

Abstract
BACKGROUND Whether there are systematic sex differences in posttraumatic stress disorder (PTSD) symptom expression remains debated. Using methods based on item response theory (IRT), we aimed at examining differences in the likelihood of reporting DSM-IV symptoms of PTSD between women and men, while stratifying for major trauma type and equating for PTSD severity. METHOD We compared data from women and men in a large nationally representative adult sample, the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses were conducted in the full population sample of individuals who met the DSM-IV criterion A (n=23,860) and in subsamples according to trauma types. RESULTS The clinical presentation of the 17 DSM-IV PTSD symptoms in the general population did not substantially differ in women and men in the full population and by trauma type after equating for levels of PTSD severity. The only exception was the symptom "foreshortened future", which was more likely endorsed by men at equivalent levels of PTSD severity. LIMITATIONS The retrospective nature of the assessment of PTSD symptoms could have led to recall bias. Our sample size was too small to draw conclusions among individuals who experienced war-related traumas. CONCLUSIONS Our findings suggest that the clinical presentation of PTSD does not differ substantially between women and men. We also provide additional psychometric support to the exclusion of the symptom "foreshortened future" from the diagnostic criteria for PTSD in the DSM-5.

Abstract
With a majority of humans now living in cities, strategic research is necessary to elucidate the impact of this evolutionarily unfamiliar habitat on neural functions and well-being. In this review, both rodent and human models are considered in the evaluation of the changing physical and social landscapes associated with urban dwellings. Animal models assessing increased exposure to artificial physical elements characteristic of urban settings, as well as exposure to unnatural sources of light for extended durations, are reviewed. In both cases, increased biomarkers of mental illnesses such as major depression have been observed. Additionally, applied human research emphasizing the emotional impact of environmental threats associated with urban habitats is considered. Subjects evaluated in an inner-city hospital reveal the impact of combined specific genetic vulnerabilities and heightened stress responses in the expression of posttraumatic stress disorder. Finally, algorithm-based models of cities have been developed utilizing population-level analyses to identify risk factors for psychiatric illness. Although complex, the use of multiple research approaches, as described herein, results in an enhanced understanding of urbanization and its far-reaching effects--confirming the importance of continued research directed toward the identification of putative risk factors associated with psychiatric illness in urban settings.

Abstract
This article examines how isolated instances of sexual violence affect adult female survivors' employment and economic well-being. This study draws on data from 27 in-depth, qualitative interviews with sexual assault survivors and rape crisis service providers. The findings suggest that sexual assault and the related trauma response can disrupt survivors' employment in several ways, including time off, diminished performance, job loss, and inability to work. By disrupting income or reducing earning power, all of these employment consequences have implications for survivors' economic well-being in the months or years following the assault. In addition, I argue that for many survivors, these employment consequences compound one another and ultimately shift survivors' long-term economic trajectories. By highlighting survivors' lived experiences of the financial aftermath of sexual assault, these findings help to illuminate the processes by which sexual violence decreases survivors' income over the life course. Understanding the financial effects of sexual violence can help researchers better understand and predict the recovery process, while helping practitioners to design more effective interventions for survivors.

Abstract
PURPOSE Traumatic events in adolescence rarely occur in isolation. Multiple traumatic experiences are prevalent, diverse and a well-established risk factor for mental health disorders. The aim of this study was to explore and explain the heterogeneity in trauma profiles in a nationally representative sample of US adolescents. METHOD Using latent class analysis, data on 10,123 adolescents aged between 13 and 18 from the National Comorbidity Survey Adolescent Supplement were examined. In addition, the relationships between the emergent classes and demographic and clinical variables were explored. RESULTS A four-class solution was the best fit of adolescent trauma patterns, with classes labelled as low risk, sexual assault risk, non-sexual risk and high risk. When compared to the low risk class, those in the other classes were significantly more likely not to live with either biological parent, display symptoms indicative of mood and anxiety disorders, and to have higher rates of disorder comorbidity. CONCLUSIONS This provides evidence of four distinct groups of adolescents who have experienced a variety of traumas. Evidence demonstrates the increased risk of adolescents with a history of trauma meeting the diagnostic criteria for not only individual disorders but also comorbidity across disorder categories.

Polyvictimization, income, and ethnic differences in trauma-related mental health during adolescence. Soc Psychiatry Psychiatr Epidemiol 2015; 50:1223-34. [PMID: 26048339 PMCID: PMC4521986 DOI: 10.1007/s00127-015-1077-3] [Citation(s) in RCA: 61] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2015] [Accepted: 05/25/2015] [Indexed: 10/23/2022]
Abstract
PURPOSE The purpose of the present study was to investigate ethnic differences in trauma-related mental health symptoms among adolescents, and test the mediating and moderating effects of polyvictimization (i.e., number of types of traumas/victimizations experienced by an individual) and household income, respectively. METHODS Data were drawn from the first wave of the National Survey of Adolescents-replication study (NSA-R), which took place in the US in 2005 and utilized random digit dialing to administer a telephone survey to adolescents ages 12-17. Participants included in the current analyses were 3312 adolescents (50.2 % female; mean age 14.67 years) from the original sample of 3614 who identified as non-Hispanic White (n = 2346, 70.8 %), non-Hispanic Black (n = 557, 16.8 %), or Hispanic (n = 409, 12.3 %). Structural equation modeling was utilized to test hypothesized models. RESULTS Non-Hispanic Black and Hispanic participants reported higher levels of polyvictimization and trauma-related mental health symptoms (symptoms of posttraumatic stress and depression) compared to non-Hispanic Whites, though the effect sizes were small (γ ≤ 0.07). Polyvictimization fully accounted for the differences in mental health symptoms between non-Hispanic Blacks and non-Hispanic Whites, and partially accounted for the differences between Hispanics and non-Hispanic Whites. The relation between polyvictimization and trauma-related mental health symptoms was higher for low-income youth than for high-income youth. CONCLUSIONS Disparities in trauma exposure largely accounted for racial/ethnic disparities in trauma-related mental health. Children from low-income family environments appear to be at greater risk of negative mental health outcomes following trauma exposure compared to adolescents from high-income families.

Abstract
OBJECTIVES Post-traumatic stress disorder (PTSD) is a major public health problem defined by three symptom clusters: intrusion thoughts, avoidance mechanisms and hyper-arousal. Several authors have emphasized, that some or all of these symptoms related to a past traumatic experience could be reactivated, even after long asymptomatic periods. This study investigates the role of an additional trauma in the reactivation of a childhood trauma among a group of former hidden children (n = 65), the Jewish youths who spent World War II in various hideaway shelters in Nazi-occupied Europe. They were compared with a control group. METHOD The presence or absence of an additional trauma in adulthood was assessed and PTSD symptoms were measured by using the Impact of Event Scale-Revised. RESULTS An additional trauma reactivates PTSD symptoms of intrusion thoughts and, marginally, symptoms of hyper-arousal. At the opposite, symptoms of avoidance were not reactivated. CONCLUSION Our results confirm the role of an additional trauma in the reactivation of traumatic memories, related to an earlier trauma, in later life. Clinical and theoretical implications are discussed and perspectives are proposed.

Abstract
Adolescents in disadvantaged communities have high rates of exposure to stress and trauma, which can negatively impact emotion regulation and executive functioning, increasing likelihood of school problems. This pilot study evaluated RAP Club, a 12-session school-based trauma-informed group intervention co-facilitated by a mental health counselor and young adult community member that utilizes evidence-based cognitive-behavioral and mindfulness strategies. Seventh and eighth graders at two urban public schools serving low-income communities were assigned to receive RAP Club (n = 29) or regular school programming (n = 20). RAP Club improved teacher-rated emotion regulation, social and academic competence, classroom behavior, and discipline. Higher program dose predicted improvements in several teacher-rated outcomes. Student self-report outcomes, however, did not vary by study group or dose. Even students with low baseline depression showed improvement in teacher-rated outcomes following program participation, supporting a model of universal program delivery to all students. Findings suggest RAP Club merits further study.

Abstract
AIMS Post-traumatic stress disorder (PTSD) is typically associated with high-risk population groups, but the risk of PTSD that is associated with trauma experienced in the community, and effect of changes in diagnostic criteria in DSM-5 on prevalence in the general population, is unknown. METHODS Cross-sectional analysis of population-based data from 4558 adults aged 25-83 years resident in Caerphilly county borough, Wales, UK. Exposure to different traumatic events was assessed using categorisation of free-text descriptions of trauma. PTSD caseness was determined using items assessing Diagnostic and Statistical Manual IV (DSM-IV) and DSM-5 A criteria and the Traumatic Screening Questionnaire. RESULTS Of the 4558 participants, 1971 (47.0%) reported a traumatic event. The most common DSM-IV A1 qualifying trauma was life-threatening illnesses and injuries (13.6%). The highest risk of PTSD was associated with assaultive violence [34.1%]. The prevalence of PTSD using DSM-IV A criteria was 14.3% (95% confidence interval [CI] = 12.8, 15.9%). Using DSM-5 A criteria reduced the prevalence to 8.0 (95% CI = 6.9, 9.4%), primarily due to exclusion of DSM-IV A1 qualifying events, such as life-threatening illnesses. CONCLUSIONS Nearly one-half of a general community sample had experienced a traumatic event and of these around one in seven was a DSM-IV case of PTSD. Although the majority of research has concentrated on combat, rape and assaultive violence, life threatening illness is a more common cause of PTSD in the community. Removal of this traumatic event in DSM-5 could reduce the number of cases of PTSD by around 6.0%.

Abstract
Post traumatic stress disorder (PTSD) is a debilitating anxiety disorder resulting from traumatic stress exposure. Females are more likely to develop PTSD than males, but neurobiological mechanisms underlying female susceptibility are lacking. This can be addressed by using nonhuman animal models. Single prolonged stress (SPS), a nonhuman animal model of PTSD, results in cued fear extinction retention deficits and hippocampal glucocorticoid receptor (GR) upregulation in male rats. These effects appear linked in the SPS model, as well as in PTSD. However, the effects of SPS on cued fear extinction retention and hippocampal GRs in female rats remain unknown. Thus, we examined sex differences in SPS-induced cued fear extinction retention deficits and hippocampal GR upregulation. SPS induced cued fear extinction retention deficits in male rats but not female rats. SPS enhanced GR levels in the dorsal hippocampus of female rats, but not male rats. SPS had no effects on ventral hippocampal GR levels, but ventral hippocampal GR levels were attenuated in female rats relative to males. These results suggest that female rats are more resilient to the effects of SPS. The results also suggest that GR upregulation and cued fear extinction retention deficits can be dissociated in the SPS model.

Abstract
BACKGROUND Millions of children are affected by acute medical events annually, creating need for resources to promote recovery. While web-based interventions promise wide reach and low cost for users, development can be time- and cost-intensive. A systematic approach to intervention development can help to minimize costs and increase likelihood of effectiveness. Using a systematic approach, our team integrated evidence on the etiology of traumatic stress, an explicit program theory, and a user-centered design process to intervention development. OBJECTIVE To describe evidence and the program theory model applied to the Coping Coach intervention and present pilot data evaluating intervention feasibility and acceptability. METHOD Informed by empirical evidence on traumatic stress prevention, an overarching program theory model was articulated to delineate pathways from a) specific intervention content to b) program targets and proximal outcomes to c) key longer-term health outcomes. Systematic user-testing with children ages 8-12 (N = 42) exposed to an acute medical event and their parents was conducted throughout intervention development. RESULTS Functionality challenges in early prototypes necessitated revisions. Child engagement was positive throughout revisions to the Coping Coach intervention. Final pilot-testing demonstrated promising feasibility and high user-engagement and satisfaction. CONCLUSION Applying a systematic approach to the development of Coping Coach led to the creation of a functional intervention that is accepted by children and parents. Development of new e-health interventions may benefit from a similar approach. Future research should evaluate the efficacy of Coping Coach in achieving targeted outcomes of reduced trauma symptoms and improved health-related quality of life.

Abstract
BACKGROUND We examined the prevalence and predictive factors of PTSD and depression in relation with peritraumatic distress, trauma exposure, and sociodemographic characteristics among children and adolescent who survived the 2010 Haiti's earthquake. METHODS We analyzed data collected between June and July 2012 from a sample of 872 participants aged 7 to 17 in 12 schools, door-to-door canvassing and two centers for street children at Port-au-Prince. Participants completed the Impact of Event Scale Revised (IES-R), Peritraumatic Distress Inventory, Child Depression Inventory 2 (CDI), and sociodemographic and traumatic exposure questionnaires. RESULTS Of 872 participants, respectively 322 (36.93%); and 403 (46.21%) reported a clinically significant symptoms of PTSD and depression, which were significantly higher among girls. The best predictive variables are peritraumatic distress for PTSD (β=0.53,P<.0001) a traumatic exposure for depression (β=0.23,P<.0001). The comorbidity between PTSD and depression symptoms is 22.25%. CONCLUSIONS This first study in children on the prevalence of PTSD and depression resulting from the 2010 Haiti earthquake demonstrates a need for improvement in treatment aimed at reducing PTSD and depression. Such treatment should be geared primarily toward girls, adolescents between the ages of 14 and 17 and those children and adolescents who have lost a family member in the earthquake.

Abstract
This study investigated the prevalence of loss due to death and its association with mental disorders in a random sample of 898 newly detained adolescents in Chicago, Illinois. Nearly 90% of youth experienced the loss of an important person; most had also experienced a "high-risk" loss (e.g., loss due to violence, sudden loss). Minority youth were at particular risk. Youth with any loss or multiple losses were more likely to have mood disorders and ADHD/behavioral disorders, respectively, than youth who had no such losses. Interventions focusing on modifiable protective factors following loss may increase positive outcomes in this vulnerable population.

Abstract
During the postnatal period, the nervous system is modified and shaped by experience, in order to adjust it to the particular environment in which the animal will live. This plasticity, one of the most remarkable characteristics of the nervous system, promotes adaptive changes, but it also makes brain more vulnerable to insults. This chapter will focus on the effects of interventions during the postnatal development in animal models of neonatal handling (usually up to 15 min of handling) and maternal separation (usually at least for 3 h). Sex-specific changes and effects of prepubertal stress such as social isolation later on in life were also considered. These interventions during development induce long-lasting traces in the pups' nervous system, which will be reflected in changes in neuroendocrine functions, including the hypothalamus-pituitary-adrenal and hypothalamus-pituitary-gonadal axes; anxiety and cognitive performance; and feeding, sexual, and social behavior. These enduring changes may be adaptive or maladaptive, depending on the environment in which the animal will live. The challenge researchers facing now is to determine how to reverse the deleterious effects that may result from early-life stress exposure.

Abstract
Trauma exposure in youth is widespread, yet symptom expression varies. The present study employs a within-scale meta-analytic framework to explore determinants of differential responses to trauma exposure. The meta-analysis included 74 studies employing samples of youth exposed to traumatic events and who completed the Trauma Symptom Checklist for Children (TSCC). Mean weighted T scores across all TSCC subscales for U.S. samples ranged between 49 and 52. Youth outside the U.S. reported higher posttraumatic stress, anxiety, and depressive symptoms, whereas those exposed to sexual abuse reported the highest posttraumatic stress, anxiety, depressive, and dissociative symptoms. Higher female representation in samples was associated with higher symptoms on all TSCC subscales except anger. In contrast, ethnic minority representation was associated with lower depressive symptoms. Moderator analyses revealed that sexual abuse, increased percentage of females, and older age were all associated with higher posttraumatic symptoms. The present meta-analytic results help elucidate some of the divergent findings on symptom expression in youth exposed to traumatic events.

Abstract
BACKGROUND Epigenetic differences exist between trauma-exposed individuals with and without post-traumatic stress disorder (PTSD). It is unclear whether these epigenetic differences pre-exist, or arise following, trauma and PTSD onset. METHOD In pre- and post-trauma samples from a subset of Detroit Neighborhood Health Study participants, DNA methylation (DNAm) was measured at DNA methyltransferase 1 (DNMT1), DNMT3A, DNMT3B and DNMT3L. Pre-trauma DNAm differences and changes in DNAm from pre- to post-trauma were assessed between and within PTSD cases (n = 30) and age-, gender- and trauma exposure-matched controls (n = 30). Pre-trauma DNAm was tested for association with post-trauma symptom severity (PTSS) change. Potential functional consequences of DNAm differences were explored via bioinformatic search for putative transcription factor binding sites (TFBS). RESULTS DNMT1 DNAm increased following trauma in PTSD cases (p = 0.001), but not controls (p = 0.067). DNMT3A and DNMT3B DNAm increased following trauma in both cases (DNMT3A: p = 0.009; DNMT3B: p < 0.001) and controls (DNMT3A: p = 0.002; DNMT3B: p < 0.001). In cases only, pre-trauma DNAm was lower at a DNMT3B CpG site that overlaps with a TFBS involved in epigenetic regulation (p = 0.001); lower pre-trauma DNMT3B DNAm at this site was predictive of worsening of PTSS post-trauma (p = 0.034). Some effects were attenuated following correction for multiple hypothesis testing. CONCLUSIONS DNAm among trauma-exposed individuals shows both longitudinal changes and pre-existing epigenetic states that differentiate individuals who are resilient versus susceptible to PTSD. These distinctive DNAm differences within DNMT loci may contribute to genome-wide epigenetic profiles of PTSD.

Abstract
This article argues that economic instability and sexual violence reinforce each other in two ways. First, the devastating psychological consequences of sexual assault can diminish work performance and disrupt income, creating economic instability, particularly for the asset-poor. Latina and African American women face particular risk due to barriers to appropriate post-assault resources and low rates of asset ownership. Second, income- and asset poverty increase women’s risk for sexual violence and complicate recovery. Women with financial and social resources can leverage these assets to both avoid and recover from sexual assault, whereas women without such resources lack these options. Policy solutions are proposed.

Abstract
OBJECTIVE Individuals with posttraumatic stress disorder (PTSD) exhibit heightened amygdala reactivity and atypical activation patterns in the medial prefrontal cortex (mPFC) in response to negative emotional information. It is unknown whether these aspects of neural function are risk factors for PTSD or consequences of either trauma exposure or onset of the disorder. We had a unique opportunity to investigate this issue following the terrorist attacks at the 2013 Boston Marathon and the ensuing manhunt and shelter in place order. We examined associations of neural function measured prior to the attack with PTSD symptom onset related to these events. METHODS A sample of 15 adolescents (mean age = 16.5 years) who previously participated in a neuroimaging study completed a survey assessing posttraumatic symptoms related to the terrorist attack. We examined blood oxygen level dependent (BOLD) response to viewing and actively down-regulating emotional responses to negative stimuli in regions previously associated with PTSD, including the amygdala, hippocampus, and mPFC, as prospective predictors of posttraumatic symptom onset. RESULTS Increased BOLD signal to negative emotional stimuli in the left amygdala was strongly associated with posttraumatic symptoms following the attack. Reduced bilateral hippocampal activation during effortful attempts to down-regulate emotional responses to negative stimuli was also associated with greater posttraumatic symptoms. Associations of amygdala reactivity with posttraumatic symptoms were robust to controls for pre-existing depression, anxiety, and PTSD symptoms and prior exposure to violence. CONCLUSIONS Amygdala reactivity to negative emotional information might represent a neurobiological marker of vulnerability to traumatic stress and, potentially, a risk factor for PTSD.

Abstract
Child maltreatment is a reliable predictor of posttraumatic stress disorder (PTSD) symptoms. However, not all maltreated children develop PTSD symptoms, suggesting that additional mediating variables explain how certain maltreated children develop PTSD symptoms and others do not. The current study tested three potential mediators of the relationship between child maltreatment and subsequent PTSD symptoms: (a) respiratory sinus arrhythmia reactivity, (b) cortisol reactivity, and (c) experiential avoidance, or the unwillingness to experience painful private events, such as thoughts and memories. Maltreated (n = 51) and nonmaltreated groups (n = 59) completed a stressor paradigm, a measure of experiential avoidance, and a semistructured interview of PTSD symptoms. One year later, participants were readministered the PTSD symptoms interview. Results of a multiple mediator model showed the set of potential mediators mediated the relationship between child maltreatment and subsequent PTSD symptoms. However, experiential avoidance was the only significant, specific indirect effect, demonstrating that maltreated children avoiding painful private events after the abuse were more likely to develop a range of PTSD symptoms 1 year later. These results highlight the importance of experiential avoidance in the development of PTSD symptoms for maltreated children, and implications for secondary prevention and clinical intervention models are discussed.

Abstract
BACKGROUND We examine prospectively the influence of two separate but potentially inter-related factors in the etiology of post-traumatic stress disorder (PTSD): childhood maltreatment as conferring a susceptibility to the PTSD response to adult trauma and juvenile disorders as precursors of adult PTSD. METHOD The Dunedin Multidisciplinary Health and Development Study (DMHDS) is a birth cohort (n = 1037) from the general population of New Zealand's South Island, with multiple assessments up to age 38 years. DSM-IV PTSD was assessed among participants exposed to trauma at ages 26-38. Complete data were available on 928 participants. RESULTS Severe maltreatment in the first decade of life, experienced by 8.5% of the sample, was associated significantly with the risk of PTSD among those exposed to adult trauma [odds ratio (OR) 2.64, 95% confidence interval (CI) 1.16-6.01], compared to no maltreatment. Moderate maltreatment, experienced by 27.2%, was not associated significantly with that risk (OR 1.55, 95% CI 0.85-2.85). However, the two estimates did not differ significantly from one another. Juvenile disorders (ages 11-15), experienced by 35% of the sample, independent of childhood maltreatment, were associated significantly with the risk of PTSD response to adult trauma (OR 2.35, 95% CI 1.32-4.18). CONCLUSIONS Severe maltreatment is associated with risk of PTSD response to adult trauma, compared to no maltreatment, and juvenile disorders, independent of earlier maltreatment, are associated with that risk. The role of moderate maltreatment remains unresolved. Larger longitudinal studies are needed to assess the impact of moderate maltreatment, experienced by the majority of adult trauma victims with a history of maltreatment.

Abstract
AIMS Exposure to extraordinary traumatic experience is one acknowledged risk factor for drug use. We aim to analyse the influence of potentially life-changing childhood stressors, experienced second-hand, on later drug use disorder in a national population of Swedish adolescent and young adults (aged 15-26 years). DESIGN We performed Cox proportional hazard regression analyses, complemented with co-relative pair comparisons. SETTING Sweden. PARTICIPANTS All individuals in the Swedish population born 1984-95, who were registered in Sweden at the end of the calendar year that they turned 14 years of age. Our follow-up time (mean 6.2 years; range 11 years) started at the year they turned 15 and continued to December 2011 (n = 1,409,218). MEASUREMENTS Our outcome variable was drug use disorder, identified from medical, legal and pharmacy registry records. Childhood stressors, as per DSM-IV stressor criteria, include death of an immediate family member and second-hand experience of diagnoses of malignant cancer, serious accidental injury and victim of assault. Other covariates include parental divorce, familial psychological wellbeing and familial drug and alcohol use disorders. FINDINGS After adjustment for all considered confounders, individuals exposed to childhood stressors 'parental death' or 'parental assault' had more than twice the risk of drug use disorder than those who were not [hazard ratio (HR) = 2.63 (2.23-3.09) and 2.39 (2.06-2.79), respectively]. CONCLUSIONS Children aged under 15 years who experience second-hand an extraordinary traumatic event (such as a parent or sibling being assaulted, diagnosed with cancer or dying) appear to have approximately twice the risk of developing a drug use disorder than those who do not.

Abstract
Previous research suggests that community violence impacts mental health outcomes, but much of this research has not (a) distinguished between different types of community violence, (b) examined gender differences, and (c) focused on youth living in urban poverty. The current study addresses these questions. Participants were 306 youth (23 % girls) and one parent/guardian receiving outpatient psychiatric services for disruptive behavior disorders in a large urban city. Youth and parents reported on youth's experience of different types of community violence (being a direct victim, hearing reports, and witnessing violence), and whether violence was directed toward a stranger or familiar. Outcomes included youth externalizing, internalizing, and posttraumatic stress symptoms assessed via parent and youth reports. Being a direct victim of violence accords risk for all mental health outcomes similarly for both boys and girls. However, gender differences emerged with respect to indirect violence, such that girls who hear reports of violence against people they know are at increased risk for all assessed mental health outcomes, and girls who witness violence against familiars are at increased risk for externalizing mental health symptoms in particular. There are gender differences in violence-related mental health etiology, with implications for intervention assessment and design.

Abstract
BACKGROUND Traumatic event reexposure in injecting drug users is associated with increased drug use and potential for psychiatric symptoms. This is the first study to examine fixed and time-varying factors that are prospectively associated with new traumatic event reexposure in injecting drug users. METHODS Injecting drug users registered in a syringe exchange program were enrolled in a 16-month parent study comparing strategies to increase drug abuse treatment enrollment. Participants (N=162) completed baseline measures of demographics, psychiatric treatment history, and lifetime traumatic event exposure. Monthly follow-ups assessed past-month traumatic event exposure, days of heroin and cocaine use, criminal activity, and drug abuse treatment participation. Generalized estimating equations models tested the influence of fixed baseline and time-varying factors on traumatic event reexposure in the same month, the following month, and two months later. RESULTS Significant fixed risk factors for traumatic event reexposure include female gender and past psychiatric treatment. In addition, each past traumatic event exposure was associated with an increased likelihood of reexposure. After accounting for all other factors, each day of cocaine use was associated with a small but persistent increased risk of traumatic event reexposure. Reexposure to a traumatic event in the prior month more than doubled the risk of subsequent reexposure. CONCLUSIONS Injecting drug users experience a pattern in which drug use is associated with increased risk of subsequent traumatic event reexposure, and traumatic event reexposure is associated with further drug use and continued reexposure. Implications for addressing these concerns in injecting drug users are presented.

Abstract
PURPOSE To assess (1) the lifetime prevalence of exposure both to trauma and post-traumatic stress disorder (PTSD); (2) the risk of PTSD by type of trauma; and (3) the determinants of the development of PTSD in the community. METHODS The Diagnostic Interview for Genetic Studies was administered to a random sample of an urban area (N = 3,691). RESULTS (1) The lifetime prevalence estimates of exposure to trauma and PTSD were 21.0 and 5.0%; respectively, with a twice as high prevalence of PTSD in women compared to men despite a similar likelihood of exposure in the two sexes; (2) Sexual abuse was the trauma involving the highest risk of PTSD; (3) The risk of PTSD was most strongly associated with sexual abuse followed by preexisting bipolar disorder, alcohol dependence, antisocial personality, childhood separation anxiety disorder, being victim of crime, witnessing violence, Neuroticism and Problem-focused coping strategies. After adjustment for these characteristics, female sex was no longer found to be significantly associated with the risk of PTSD. CONCLUSIONS The risk for the development of PTSD after exposure to traumatic events is associated with several factors including the type of exposure, preexisting psychopathology, personality features and coping strategies which independently contribute to the vulnerability to PTSD.

Abstract
BACKGROUND The objective of this study is to investigate the association between childhood trauma and lipid profiles in adults from a highly traumatized population at-risk for cardiovascular disease. METHOD We recruited 452 participants, primarily African-American and of low socioeconomic status, from general medical clinics in a large urban hospital. We performed direct comparisons, univariate analysis of variance and regression analyses together and separated by sex, examining the associations of child abuse, body mass index, lipid lowering drug use, blood pressure, age, and substance use to HDL levels and HDL/LDL ratios. RESULTS A history of moderate to severe levels of childhood trauma and abuse was associated with a significant decrease in HDL levels (P ≤ .01) and HDL/LDL ratios (P ≤ .001) relative to males with low levels of abuse. This relationship held when the status of lipid-lowering drugs was considered. When controlling for age, substance abuse, tobacco use, and adult trauma, the effects of childhood trauma remained significant. We found a significant child abuse by sex interaction on HDL/LDL ratios [F(1,369)=13.0, P ≤ .0005] consistent with a differential effect of trauma on dyslipidemia in male but not female subjects. CONCLUSIONS Our data suggest that childhood trauma exposure, obtained with self-report measures, may contribute to increased risk of cardiovascular disease by way of stress-mediated alterations of lipid concentration and composition in male, but not female, subjects.

Abstract
Broad associations between trauma exposure (TE) and Axis I psychopathology have been noted in the literature. However, it is not clear if TE is directly associated with Axis I disorders or if the relationship is better accounted for by familial factors (i.e., early environment and/or genetic factors). The current investigation used the co-twin control method in a large sample of adult twin pairs from the Norwegian Twin Registry (N = 2,776), including 449 twin pairs discordant for DSM-IV Criterion A TE. History of TE and Axis I psychopathology was assessed using DSM-IV based clinical interview. Results suggested that TE was significantly associated with greater likelihood of meeting criteria for major depression, dysthymia, anxiety, substance abuse, eating disorders, and somatization disorder in the general population (odds ratios [OR] ranging from 1.33 to 2.21). Among twins discordant for TE, results suggested that TE may exert a direct influence on major depression, dysthymia, anxiety, substance abuse, eating disorders, and somatization disorder. Shared familial effects may also account for at least some of the relationship between TE and major depression. TE may play an important role in the development of a wide range of Axis I psychopathology above and beyond familial factors. Research and clinical implications are discussed.

Abstract
This article investigates gender differences in trauma symptoms from baseline to end of treatment (trauma-focused cognitive behavioral therapy or parent-child interaction therapy) in children ages 7-18 years. Multivariate analysis of covariance (MANCOVA) and trend analysis using analysis of covariance (ANCOVA) were conducted on baseline and end of treatment University of California at Los Angeles Posttraumatic Stress Disorder Reaction Index (UCLA PTSD-RI) total scores. Results suggest that female children start at higher reported total posttraumatic stress disorder rates than males, but both groups experience significant symptom reduction during the course of treatment. At posttreatment, girls are still reporting higher symptom levels on the UCLA PTSD-RI than boys, suggesting that their clinical presentation at discharge may differ despite significant treatment gains. A full factorial model including the interaction of dose and gender was not significant. Identification of these gender-specific response patterns are an important consideration in treatment and discharge planning for children who have been trauma-exposed and are presenting for treatment with post trauma exposure disturbances.

Abstract
We examined relations of posttraumatic stress disorder (PTSD) symptoms with dimensions of trauma, including environment (Domestic vs. Community) and proximity (Indirect vs. Direct trauma) among inner-city youth. Participants (n = 65) reported traumatic events they had experienced on a version of the UCLA PTSD Reaction Index Trauma Exposure Screen, and reported PTSD symptoms with the PTSD Checklist--Civilian version (PCL-C). High rates of trauma and PTSD were found, consistent with other reports of inner-city youth. The 49% of youth surveyed met criteria for PTSD on the PCL-C symptom scale with a score cutoff of 35. Females reported elevated PTSD symptom scores and a higher incidence of Domestic trauma than did males but similar incidence of other trauma types. When males and females were combined, Domestic trauma significantly correlated with each of the PTSD symptom clusters of intrusions, numbing/avoidance, and hyperarousal. When participants with Community trauma were excluded from analyses to reduce confounding environmental influence, Domestic trauma marginally correlated with numbing/avoidance symptoms. Our findings suggest that Domestic trauma may result in more emotional numbing/avoidance symptoms than other types of trauma. Further analyses suggested that Community trauma may result in more intrusions and hyperarousal symptoms rather than emotional numbing. Environmental aspects of trauma, rather than the proximity of trauma, may have greater impact on presentation of PTSD. Future studies with larger samples are needed to confirm these findings.

Abstract
BACKGROUND Genetics of Recurrent Early-Onset Depression study (GenRED II) data were used to examine the relationship between posttraumatic stress disorder (PTSD) and attempted suicide in a population of 1,433 individuals with recurrent early-onset major depressive disorder (MDD). We tested the hypothesis that PTSD resulting from assaultive trauma increases risk for attempted suicide among individuals with recurrent MDD. METHODS Data on lifetime trauma exposures and clinical symptoms were collected using the Diagnostic Interview for Genetic Studies version 3.0 and best estimate diagnoses of MDD, PTSD, and other DSM-IV Axis I disorders were reported with best estimated age of onset. RESULTS The lifetime prevalence of suicide attempt in this sample was 28%. Lifetime PTSD was diagnosed in 205 (14.3%) participants. We used discrete time-survival analyses to take into account timing in the PTSD-suicide attempt relationship while adjusting for demographic variables (gender, race, age, and education level) and comorbid diagnoses prior to trauma exposure. PTSD was an independent predictor of subsequent suicide attempt (HR = 2.5, 95% CI: 1.6, 3.8; P < .0001). Neither assaultive nor nonassaultive trauma without PTSD significantly predicted subsequent suicide attempt after Bonferroni correction. The association between PTSD and subsequent suicide attempt was driven by traumatic events involving assaultive violence (HR = 1.7, 95% CI: 1.3, 2.2; P< .0001). CONCLUSIONS Among those with recurrent MDD, PTSD appears to be a vulnerability marker of maladaptive responses to traumatic events and an independent risk factor for attempted suicide. Additional studies examining differences between those with and without PTSD on biological measures might shed light on this potential vulnerability.

Abstract
The aim of this study is to identify protective and risk factors related to the development of posttraumatic stress disorder (PTSD) on a sample of survivors from a single plane crash. Eighteen survivors were examined 6 months following the event. The subjects all underwent psychiatric interviews, Clinician-Administered PTSD Scale structured interviews, personality and cognitive tests. Only 38.9% of them presented with all of the symptoms of PTSD; 22.2% showed no symptoms for PTSD; remaining survivors exhibited emotional/affective symptoms related to the event. In addition to the severity of the traumatic event itself, other risk factors identified were the loss of a relative, the manifestation of depressive symptoms, and the severity of physical injuries sustained. Low levels of hostility and high levels of self-efficacy represented protective factors against developing PTSD.

Abstract
We investigated the lifetime exposure to traumatic events and symptoms of post-traumatic stress disorder, depression, and anxiety among 1337 students at a large residential university in South Africa. Traumatic events were assessed using the Stressful Life Events Scaling Questionnaire, and the symptoms of post-traumatic stress, depression, and anxiety were measured using the Post-Traumatic Stress Disorder Symptom Scale–Self Report Version, the Beck Depression Inventory, and the Beck Anxiety Inventory, respectively. The sample consisted of females ( n = 857) and males ( n = 480). Approximately 90% of the sample reported at least one traumatic event in their lifetime, and male and female students reported similar levels of exposure to traumatic events. With regard to symptoms of post-traumatic stress, those students who had experienced a traumatic event reported more severe post-traumatic stress symptoms than those students who had not. Significant correlations were found among symptoms of post-traumatic stress, depression, and anxiety. The significant predictors of the severity of post-traumatic stress symptoms were gender, Black race, Coloured race, and year of study. The significant predictors of the frequency of traumatic events were gender, age, Black race, Coloured race, and private residence. These results are compared with South African trauma-related studies as well as findings from other countries.

[PMID: 23880492 PMCID: PMC3724231 DOI: 10.1016/j.jaac.2013.05.011] [Citation(s) in RCA: 398] [Impact Index Per Article: 36.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2013] [Revised: 04/09/2013] [Accepted: 05/17/2013] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Although exposure to potentially traumatic experiences (PTEs) is common among youths in the United States, information on posttraumatic stress disorder (PTSD) risk associated with PTEs is limited. We estimate lifetime prevalence of exposure to PTEs and PTSD, PTE-specific risk of PTSD, and associations of sociodemographics and temporally prior DSM-IV disorders with PTE exposure, PTSD given exposure, and PTSD recovery among U.S. adolescents. METHOD Data were drawn from 6,483 adolescent-parent pairs in the National Comorbidity Survey Replication Adolescent Supplement (NCS-A), a national survey of adolescents aged 13 through 17 years. Lifetime exposure to interpersonal violence, accidents/injuries, network/witnessing, and other PTEs was assessed along with DSM-IV PTSD and other distress, fear, behavior, and substance disorders. RESULTS A majority (61.8%) of adolescents experienced a lifetime PTE. Lifetime prevalence of DSM-IV PTSD was 4.7% and was significantly higher among females (7.3%) than among males (2.2%). Exposure to PTEs, particularly interpersonal violence, was highest among adolescents not living with both biological parents and with pre-existing behavior disorders. Conditional probability of PTSD was highest for PTEs involving interpersonal violence. Predictors of PTSD among PTE-exposed adolescents included female gender, prior PTE exposure, and pre-existing fear and distress disorders. One-third (33.0%) of adolescents with lifetime PTSD continued to meet criteria within 30 days of interview. Poverty, U.S. nativity, bipolar disorder, and PTE exposure occurring after the focal trauma predicted nonrecovery. CONCLUSIONS Interventions designed to prevent PTSD in PTE-exposed youths should be targeted at victims of interpersonal violence with pre-existing fear and distress disorders, whereas interventions designed to reduce PTSD chronicity should attempt to prevent secondary PTE exposure.

The role of intelligence in posttraumatic stress disorder: does it vary by trauma severity? PLoS One 2013; 8:e65391. [PMID: 23762357 PMCID: PMC3677906 DOI: 10.1371/journal.pone.0065391] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2013] [Accepted: 04/30/2013] [Indexed: 11/22/2022] Open
Abstract
Background Only a small minority of trauma victims develops post-traumatic stress disorder (PTSD), suggesting that victims vary in their predispositions to the PTSD response to stressors. It is assumed that the role of predispositions in PTSD varies by trauma severity: when stressors are less severe, predispositions play a bigger role. In this study, we test whether the role of intelligence in PTSD varies by trauma severity. Specifically, does low intelligence plays a bigger part among victims of lower magnitude stressors than among victims of extreme stressors? Methods Data come from a longitudinal study of randomly selected sample in Southeast Michigan (n = 713). IQ was measured at age 6. PTSD was measured at age 17, using the NIMH-DIS for DSM-IV. Stressors were classified as extreme if they involved assaultive violence (e.g. rape, sexual assault, threatened with a weapon); other stressors in the list (e.g. disaster, accidents) were classified as lower magnitude. Assaultive violence victims had experienced assaultive violence plus other event types or only assaultive violence. Victims of other stressors were participants who had never experienced assaultive violence. We compared the influence of age 6 IQ on PTSD among persons exposed to assaultive violence vs. other stressors, using multinomial logistic regression. Results Relative risk ratio (RRR) for PTSD associated with a one point drop in age 6 IQ among victims of assaultive violence was 1.04 (95% CI 1.01, 1.06); among victims of other stressors, it was 1.03 (95% CI 0.99, 1.06). A comparison of the two RRRs indicates no significant difference between the two estimates (p = 0.652). IQ does not play a bigger role in PTSD among victims of other stressors than it does among victims of assaultive violence. Conclusions Lower IQ exerts an adverse PTSD effect on trauma victims, with no evidence of variability by the severity of trauma they have experienced.

Abstract
OBJECTIVE Identifying the comparative contributions of different forms of violence exposure to trauma sequelae can help to prioritize interventions for polyvictimized youth living in contexts of limited mental health resources. This study aimed to establish gender patterns in the independent and comparative contributions of five types of violence exposure to the severity of posttraumatic stress symptoms among Xhosa-speaking South African adolescents. METHOD Xhosa-speaking adolescents (n=230) attending a high school in a low-income urban community in South Africa completed measures of violence exposure and posttraumatic stress symptoms. RESULTS While witnessing of community violence was by far the most common form of violence exposure, for the sample as a whole only sexual victimization and being a direct victim of community violence, together with gender, contributed independently to the severity of posttraumatic stress symptoms. When the contribution of different forms of violence was examined separately for each gender, only increased exposure to community and sexual victimization were associated with symptom severity among girls, while increased exposure to direct victimization in both the community and domestic settings were associated with greater symptom severity in boys. CONCLUSIONS The findings provide some preliminary motivation for focusing trauma intervention initiatives in this community on girls who have experienced sexual abuse compounded by victimization in the community, and boys who have been direct victims of either domestic or community violence. Further research is required to establish whether the risk factors for posttraumatic stress symptoms identified among adolescents in this study are consistent across different communities in South Africa, as well as across other resource-constrained contexts.

Abstract
This study investigated the factor structure and correlates of posttraumatic stress-disorder (PTSD) symptoms among children and adolescents confronted with the death of a loved one. Three hundred thirty-two bereaved children and adolescents (aged 8-18; 56.9 % girls) who all received some form of psychosocial support after their loss, completed self-report measures of PTSD, together with measures tapping demographic and loss-related variables, depression, prolonged grief, and functional impairment. Parent-rated indices of impairment were also collected. We first evaluated the fit of six alternative models of the factor structure of PTSD symptoms, using confirmatory factor analyses. Outcomes showed that the 4-factor numbing model from King et al. (Psychological Assessment 10, 90-96, 1998), with distinct factors of reexperiencing, avoidance, emotional numbing, and hyperarousal fit the data best. Of all participants, 51.5 % met DSM-IV criteria for PTSD. PTSD-status and scores on the PTSD factors varied as a function of age and gender, but were unrelated to other demographic and loss-related variables. PTSD-status and scores on the PTSD factors were significantly associated symptom-levels of depression, prolonged grief, and functional impairment. Findings complement prior evidence that the DSM-IV model of the factor structure of PTSD symptoms may not represent the best conceptualization of these symptoms and highlight the importance of addressing PTSD symptoms in children and adolescents seeking help after bereavement.

Abstract
The objective was to study the accuracy of the post-traumatic stress disorder (PTSD) section of the Composite International Diagnostic Interview (CIDI 2.1) DSM-IV diagnosis, using the Structured Clinical Interview (SCID) as gold standard, and compare the ICD-10 and DSM IV classifications for PTSD. The CIDI was applied by trained lay interviewers and the SCID by a psychologist. The subjects were selected from a community and an outpatient program. A total of 67 subjects completed both assessments. Kappa coefficients for the ICD-10 and the DSM IV compared to the SCID diagnosis were 0.67 and 0.46 respectively. Validity for the DSM IV diagnosis was: sensitivity (51.5%), specificity (94.1%), positive predictive value (9.5%), negative predictive value (66.7%), misclassification rate (26.9%). The CIDI 2.1 demonstrated low validity coefficients for the diagnosis of PTSD using DSM IV criteria when compared to the SCID. The main source of discordance in this study was found to be the high probability of false-negative cases with regards to distress and impairment as well as to avoidance symptoms.

Abstract
PURPOSE Youth in foster care represent a highly traumatized population. However, trauma research on this population has focused primarily on maltreatment rather than the full spectrum of trauma experiences identified within the DSM-IV. The current study aims to fill this gap by reporting the prevalence of exposure to specific types of traumatic events for a large sample of youth with foster care experience. The study also reports the likelihood of lifetime PTSD diagnoses associated with each specific type of trauma. METHOD Data are from a longitudinal panel study of 732 adolescents aged 17 and 18 who were in foster care. Lifetime trauma exposure and PTSD diagnosis were assessed using the Composite International Diagnostic Interview. Statistical comparisons were made using logistic regressions. RESULTS The majority of respondents had experienced at least one trauma in their lifetime. While overall trauma prevalence did not differ by gender, males were more likely to experience interpersonal violence and environmental trauma, while females were more likely to experience sexual trauma. Caucasian participants reported higher rates of trauma exposure than African-American participants did. The types of trauma associated with the highest probability of a lifetime PTSD diagnosis were rape, being tortured or a victim of terrorists, and molestation. CONCLUSIONS Youth in foster care are a highly traumatized population and meet diagnostic criteria for PTSD at higher rates than general youth populations. The ongoing impact of trauma may be particularly problematic for these young people given their abrupt transition to independence.

Abstract
BACKGROUND Only a minority of trauma victims (<10%) develops post-traumatic stress disorder (PTSD), suggesting that victims vary in predispositions to the PTSD response to traumas. It is assumed that the influence of predispositions is inversely related to trauma severity: when trauma is extreme predispositions are assumed to play a secondary role. This assumption has not been tested. We estimate the influence of key predispositions on PTSD induced by an extreme trauma - associated with a high percentage of PTSD - (sexual assault), relative to events of lower magnitude (accidents, disaster, and unexpected death of someone close). METHOD The National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) is representative of the adult population of the USA. A total of 34 653 respondents completed the second wave in which lifetime PTSD was assessed. We conducted three series of multinomial logistic regressions, comparing the influence of six predispositions on the PTSD effect of sexual assault with each comparison event. Three pre-existing disorders and three parental history variables were examined. RESULTS Predispositions predicted elevated PTSD risk among victims of sexual assault as they did among victims of comparison events. We detected no evidence that the influence of predispositions on PTSD risk was significantly lower when the event was sexual assault, relative to accidents, disasters and unexpected death of someone close. CONCLUSIONS Important predispositions increase the risk of PTSD following sexual assault as much as they do following accidents, disaster, and unexpected death of someone close. Research on other predispositions and alternative classifications of event severity would be illuminating.

Abstract
Women who experience traumatic events are at higher risk for mental health problems compared to men; however, gaps remain in our understanding of this disparity. A sample of 170 urban adults completed self-report measures. Women were significantly more likely to experience sexual assault and domestic violence compared to men, and they were significantly less likely to experience a robbery or mugging, being threatened with a weapon, or witnessing a death or assault compared to men. Also, women were more likely than men to meet criteria for probable post-traumatic stress disorder (PTSD) and depression after controlling for covariates and trauma level. Our findings suggest a possible differential vulnerability to the development of PTSD and depressive symptoms in women.
