Anxiety sensitivity, finding the body, and posttraumatic stress disorder in suicide-bereaved treatment-seeking adults.

Those bereaved by suicide are at greater risk of prolonged distress compared to those bereaved by other modes of death. Trauma- and emotion-related factors may increase this vulnerability. Finding the body of the deceased may intensify postsuicide distress. Anxiety sensitivity, fear of one's anxiety-related symptoms, has been positively associated with posttraumatic stress disorder (PTSD) in other trauma populations but has not been studied in the suicide bereaved. This study examined the relationships among finding the body, anxiety sensitivity, and PTSD in a treatment-seeking, suicide-bereaved sample (N = 50). Pretreatment baseline data on demographics, the Anxiety Sensitivity Index, and the PTSD Checklist were analyzed. Younger age (r = -.31, p = .03), being a person of color (r = -.32, p = .02), and fewer days since the loss (r = -.30, p = .03) were associated with greater PTSD. Controlling for age, race, and days since the loss, PTSD was unrelated to finding the body, F(1, 45) = 0.01, p = .92, but was positively associated with anxiety sensitivity (pr = .32, p = .03). In simultaneous regression analyses, age, race, days since the loss, finding the body, and anxiety sensitivity accounted for 33% of the variance in PTSD, F(2, 44) = 4.29, p = .003; anxiety sensitivity was the only significant predictor of PTSD symptoms (β = .36, t = 2.35, p = .02). Anxiety sensitivity has important implications for the development and maintenance of PTSD in the suicide bereaved and should be assessed and targeted in suicide postvention.

The Role of Adverse Childhood Experiences on People in Opiate Agonist Treatment: The Importance of Feeling Unloved

Introduction: Adults in opiate agonist treatment (OAT) often have a background of adverse childhood experiences (ACEs) and are more likely to be exposed to a variety of risks that may trigger post-traumatic stress disorder (PTSD). Summative ACE scores are often used to identify individuals at risk of PTSD and continued substance use. What has not been addressed is whether specific ACE factors are exerting a greater influence on the individual. This study investigated whether specific ACEs predicted PTSD, and current continued substance use among adults in long-term OAT. Methods: An analysis of data that were collected at the follow-up stage of a study among 131 adults who attended OAT was conducted. Participants attended one of six OAT settings, covering 45% (n = 890) of clients in a defined area of Dublin, Ireland in 2017. Interviews were conducted with 104 participants, 66 males (63%) and 38 females (37%), with an average age of 43 years (SD = 7.4). The Adverse Childhood Questionnaire (ACQ); PTSD checklist (PCL-5); heroin; tranquilliser; cannabis; alcohol; and cocaine used in the previous 28 days were measured using the quantity used score within the Opiate Treatment Index. Socio‐demographics and age of first use of these four substances were also collected. The analysis has focussed on relating ACEs to PTSD, age of first drugs use, and current drug use of the participants. Results: Bivariate analysis showed that the summative ACQ score was significantly correlated with age of first opiate use (p = 0.004). Multiple regression analysis showed that the summative ACQ score and tranquilliser use predicted higher levels of PTSD (R² = 0.50). Four specific ACEs predicted 54% of the variance in PTSD, these were feeling unloved (β = 0.328) living with a household member who had a problem with alcohol or used illicit street drugs (β = 0.280); verbal abuse (β = 0.219); and living with a person who had a mental illness (β = 0.197). Conclusions: While a summation of all ten ACEs predicted higher levels of PTSD, the factor “feeling unloved” as a child provided the single strongest predictor and may represent an overarching risk of PTSD and continued substance use in later life among adults in treatment for an opiate use disorder.

Psychosocial aspects of coping that predict post-traumatic stress disorder for African American survivors of homicide victims

African Americans disproportionately experience homicide, and the psychological consequence of experiencing this traumatic event interferes with daily function, often in the form of post-traumatic stress disorder (PTSD). According to the Model of Coping for African American Survivors of Homicide Victims (MCAASHV), African Americans coping with the traumatic impact of homicide are influenced by: the violent nature of the death itself, racial- and cultural-bound experiences (e.g., cultural trauma, the culture of homicide including stigma, blame, shame, and lack of justice) and psychological processes including racial appraisal and coping strategies (e.g., spiritual, collective, meaning making). This study examined the direct and indirect effects racial- and cultural-bound experiences have on PTSD through coping strategies among 304 African American survivors of homicide victims across the United States using Qualtrics Panel collected in March–May 2018. The path analysis model demonstrated strong model fit, and the variables in the model accounted for 34% variance in PTSD. Coping (β = −0.38, p < .001) and culture of homicide (β = −0.27, p < .001) were negatively related to PTSD. Cultural trauma (β = 0.11, p < .014), culture of homicide (β = 0.43, p < .001), reactions to homicide (β = 0.11, p < .006) and racial appraisal (β = 0.32, p < .001) were positively associated with coping (R2 = 52%), and all were indirectly associated with PTSD through coping. Findings provide strong support for the MCAASHV and highlight the direct and indirect effects of racial and cultural experiences of coping that explain PTSD among African Americans chronically exposed to homicide.

Prevalence, New Incidence, Course, and Risk Factors of PTSD, Depression, Anxiety, and Panic Disorder during the Covid-19 Pandemic in 11 Countries.

We aimed to evaluate the prevalence and incidence of post-traumatic stress disorder (PTSD), depression, anxiety, and panic disorder (PD) among citizens in 11 countries during the Covid-19 pandemic. We explored risks and protective factors most associated with the development of these mental health disorders and their course at 68 days follow up. We acquired 9543 unique responses via an online survey that was disseminated in UK, Belgium, Netherlands, Bulgaria, Czech Republic, Finland, India, Latvia, Poland, Romania, and Sweden. The prevalence and new incidence during the pandemic for at least one disorder was 48.6% and 17.6%, with the new incidence of PTSD, anxiety, depression, and panic disorder being 11.4%, 8.4%, 9.3%, and 3%, respectively. Higher resilience was associated with lower mental health burden for all disorders. Ten to thirteen associated factors explained 79% of the variance in PTSD, 80% in anxiety, 78% in depression, and 89% in PD. To reduce the mental health burden, governments should refrain from implementing many highly restrictive and lasting containment measures. Public health campaigns should focus their effort on alleviating stress and fear, promoting resilience, building public trust in government and medical care, and persuading the population of the measures’ effectiveness. Psychosocial services and resources should be allocated to facilitate individual and community-level recovery from the pandemic.

The Glucocorticoid Receptor Gene (NR3C1) 9β SNP Is Associated with Posttraumatic Stress Disorder.

Posttraumatic stress disorder (PTSD) has been associated with glucocorticoid (GC) hypersensitivity. Although genetic factors account for 30–46% of the variance in PTSD, no associations have been found between single nucleotide polymorphisms (SNPs) of the GC receptor (GR) gene (NR3C1) and risk for this disorder. We studied the association of five SNPs in the GR gene (rs10052957, rs6189/rs6190, rs6195, rs41423247, and rs6198) and haplotypes with PTSD, in a group of Portuguese male war veterans (33 with lifetime PTSD, 28 without). To determine whether the 9β SNP (rs6198) was associated with chronically altered cortisol levels, we evaluated hair cortisol concentrations (HCC) in a sample of 69 veterans’ offspring. The 9β variant (G allele) was significantly associated with lifetime PTSD under a dominant model of inheritance. The 9β variant was also significantly associated with severity of current PTSD symptoms. The haplotype analysis revealed an association between a common haplotype comprising the 9β risk allele and lifetime PTSD. Carriers of the 9β risk allele had significantly lower HCC than non-carriers. We found the 9β risk allele and a haplotype comprising the 9β risk allele of the GR gene to be associated with PTSD in veterans. This 9β risk allele was also associated with lower HCC in their offspring.

Emotion regulation as a transdiagnostic factor in Afghan refugees.

In response to the high rates of comorbidity as well as the severe social impairment among refugees, the examination of transdiagnostic factors such as emotion regulation appears particularly promising in this group. This study investigates the contribution of difficulties in emotion regulation to the self-reported symptom levels of posttraumatic stress disorder (PTSD), depression, and anxiety/insomnia, which are highly prevalent symptoms among refugees. In addition, the link between emotion regulation and social impairment is examined. Participants were 74 male Afghan refugees exposed to trauma. They completed measures of trauma exposure, difficulties in emotion regulation (Difficulties in Emotion Regulation Scale), PTSD (PTSD Checklist for DSM-5), depression, anxiety/insomnia, and social impairment (General Health Questionnaire-28). Higher symptom severities of PTSD, depression, and anxiety/insomnia were related to the Difficulties in Emotion Regulation Scale subscales nonacceptance, goals, impulse, strategies, and clarity, but none of our outcomes was related to lack of emotional awareness. Difficulties in emotion regulation accounted for significant variance in PTSD, depression, and anxiety/insomnia beyond demographics and trauma exposure. When predicting social impairment, difficulties in emotion regulation accounted for significant variance beyond PTSD and anxiety/insomnia but not beyond depression. The findings indicate that emotion regulation may be a transdiagnostic key factor contributing to symptoms of different mental disorders as well as social impairment in trauma-exposed refugees. It highlights the need and potential directions for transdiagnostic interventions that target these difficulties. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Sleep Quality Moderates the Relationship between Anxiety Sensitivity and PTSD Symptoms in Combat-exposed Veterans

ABSTRACT Objective/Background: Posttraumatic stress disorder (PTSD) and related conditions (e.g., depression) are common in Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND) veterans. High anxiety sensitivity (AS), defined as fear of anxiety and anxiety-related consequences, is related to greater PTSD and depressive symptoms; however, few studies have identified possible modifiers of these associations. The current study examined the moderating role of sleep quality in the associations between AS and PTSD and depressive symptoms. Participants: Participants were 155 OEF/OIF/OND community veterans ages 21–40 (12.3% women). Methods: Participants completed a semi-structured clinical interview for DSM-IV PTSD symptoms (Clinician Administered PTSD Scale; CAPS) and self-report measures of anxiety sensitivity (Anxiety Sensitivity Index), sleep quality (Pittsburgh Sleep Quality Index global score; PSQI), and depressive symptoms (Beck Depression Inventory-II; BDI–II). Results: Results of hierarchical linear regression models indicated that the main effects of AS and global PSQI score were significantly associated with greater PTSD and depressive symptoms (both with sleep items removed), above and beyond the covariates of trauma load and military rank. Sleep quality moderated the relationship between AS and PTSD symptoms (but not depressive symptoms), such that greater AS was associated with greater PTSD symptoms for individuals with good sleep quality, but not poor sleep quality. Conclusions: Sleep quality and AS account for unique variance in PTSD and depressive symptoms in combat-exposed veterans. AS may be less relevant to understanding risk for PTSD among combat-exposed veterans experiencing poor sleep quality.

Posttraumatic cognitions, childhood sexual abuse characteristics, and posttraumatic stress disorder in men who have sex with men

BackgroundHigh rates of experience of childhood sexual abuse (CSA) among in men who have sex with men (MSM) place this population at increased risk for posttraumatic stress disorder (PTSD). ObjectiveThis study explores how specific characteristics of CSA relate to posttraumatic cognitions (PTCs) and explores the role that specific PTCs play in the relationship between CSA and PTSD in MSM. MethodsTwo-hundred and ninety MSM completed a CSA interview, the Davidson Trauma Scale, and the Posttraumatic Cognitions Inventory. ResultsControlling for sociodemographic factors, CSA involving physical injury and CSA with intense fear were associated with higher levels of PTCs about the self and world, but not with self-blame. We did not find significant associations for CSA involving a family member, CSA with penetration, or duration or frequency of CSA with any subscale on the PTCI. Experiencing CSA for the first time during adolescence was associated with higher self-blame. Analyses revealed that physical injury and intense fear each had indirect effects on PTSD symptoms through negative cognitions about the self and world. First CSA episode during adolescence had an indirect effect on PTSD symptoms through self-blame. CSAs accounted for 16.7% and PTCs accounted for 31.7% of the variance in PTSD, underlining the importance of PTCs. ConclusionsAssessing for physical injury, intense fear, and age at first CSA are particularly relevant to PTCs and of critical importance to advancing assessment and treatment strategies for PTSD in MSM.

Pain and posttraumatic stress disorder in refugees who survived torture: The role of pain catastrophizing and trauma-related beliefs.

Traumatized refugees with comorbid pain report more severe posttraumatic stress disorder (PTSD), respond less well to PTSD-focused treatments and exhibit greater disability. A mutually maintaining relationship may exist between pain and PTSD, that may be partly accounted for by depression, but no prior studies have tested this assumption in traumatized refugees. Self-report measures of pain, PTSD, depression, disability, pain catastrophizing (PC) and trauma-related beliefs (TRBs) were administered to 197 refugees referred to the Danish Institute Against Torture (DIGNITY) prior to treatment. The contribution of pain, depression, PC, and TRBs to the overall variance in PTSD severity was examined. We also examined whether the relationship between pain and PTSD was mediated by PC and TRBs, after controlling for depression. Depression, pain severity, PC and TRBs together accounted for 66% of the overall variance in PTSD, with depression being the primary contributor (57%). In univariate tests, both PC and TRBs significantly mediated the relationship between pain interference/severity and PTSD. However, after controlling for depression only PC mediated this relationship. Negative beliefs about pain and the trauma made small, but additive contributions to the relationship between pain and PTSD severity, after controlling for depression. Longitudinal studies with refugees, involving tests of more complex mutual maintenance models, are warranted. After controlling for symptoms of depression, pain catastrophizing and negative trauma-related beliefs partly mediated the relationship between pain and PTSD in tortured refugees. The results suggest that all three variables are important in a mutual mediation model of pain and PTSD, and as targets for treatment, in traumatized refugees.

The Nomological Network of a Behavioral Distress Tolerance Task in Veterans.

There is a relative lack of research on distress tolerance (DT) in veteran samples. The aims of the study were to (a) evaluate convergent and discriminant validity of a behavioral measure of DT compared to theoretically similar (i.e., self-report DT, negative urgency) and dissimilar (i.e., risk-taking) constructs and (b) evaluate the concurrent validity of DT in relation to posttraumatic stress disorder (PTSD) and depressive symptoms in a veteran sample. A sample of U.S. veterans who served after the September 11, 2001 terror attacks (N = 306, 89.9% male; M age 30.2 years, SD = 4.5, range: 21-40 years) completed self-report and behavioral measures of DT, risk-taking, impulsivity, and depressive symptoms, and completed a clinical interview for PTSD. Results of a multitrait-multimethod matrix found significant yet minimal shared variance, r2 = .01-.03, ps = .002-.055, between the self-report and behavioral measures of DT. We used a series of multiple regressions to examine the relative contribution of the behavioral and self-report DT measures in the prediction of PTSD and depressive symptoms. Self-reported, but not behavioral, DT accounted for unique variance in PTSD, r2 = .12, p < .001, and depressive symptoms, r2 = .23, p < .001. Participants with PTSD or higher scores on measures of depression were more likely to report greater increases in frustration and irritability after completing the behavioral task. Results indicate that DT is not a unidimensional construct and must be considered in the context of specific emotions (e.g., tolerance of irritability vs. fear) and contexts (e.g., behavioral, affective).

Direct and indirect psychological impacts of shark-bite events.

Shark bites are rare, with intense media exposure. There are no known studies of the psychological impacts of this specific type of traumatic event. This is the first study that describes those directly and indirectly affected, and evaluates the prevalence of post-traumatic stress disorder (PTSD) and related risk factors. In total, 124 members of an Australian shark-bite peer-support group were invited to complete an online survey assessing demographic, event, media and psychological factors. Response rate was 48% ( n = 60, 63% male, 44 ± 14 years). Retrospective and current measures of PTSD (PTSD Checklist for DSM-5 [PCL-5]) and suicidality (Suicidal Ideation Attributes Scale [SIDAS-5]) were used. Post-event PTSD was prevalent in this sample ( n = 16/59, 27.1%, 95% confidence interval [CI] = [15.4, 38.8]), but less so currently ( n = 2/55, 3.6%, 95% CI = [0.0, 8.7]). In addition, nine ( n = 9/59, 15.3%, 95% CI = [5.8, 24.7]) had subthreshold, but highly symptomatic, syndromes post event. There was no association of PTSD with direct/indirect bite involvement, gender, or prior trauma. Two respondents were at risk of suicidal behaviour. PTSD was commonly reported by those without a partner (odds ratio [OR] = 5.91, 95% CI = [1.52, 22.99], p = 0.01) or with two friends or fewer to rely on (OR = 5.83, 95% CI = [1.62, 21.01], p = 0.01). PTSD was more likely in those with a negative media experience ( n = 34/52, 65.4%, OR = 11.90, 95% CI = [1.42, 100.04], p = 0.02) and 61.5% ( n = 32/52) of respondents reported media coverage lasting months or years. In multivariate modelling, negative media impact, relationship status and friendships were independently associated with PTSD and explained much of the variance in PTSD ( F4,41 = 10.94, p < 0.0001, r2 = 0.52). Nearly one-third of members of an Australian shark-bite peer-support group report post-event PTSD, and one-quarter of these were not present at the time of the event. Findings support interventions targeting negative media impact, similar to media reporting guidelines for suicide, and enhancing social support.

Anger as an underlying dimension of posttraumatic stress disorder

In this study, we examined the underlying role of anger in posttraumatic stress disorder (PTSD). Although anger is currently considered within two symptoms of PTSD (i.e., anger/irritability; and negative emotional state), some research has found that anger is more than just a diagnostic symptom of PTSD. The sample consisted of 375 trauma-exposed individuals that completed the PTSD Checklist-5 and Dimensions of Anger Reactions Scale. Confirmatory factor analysis was used to assess PTSD's factor structure based on the four-factor DSM-5 PTSD model. Subsequently, the model was re-tested, statistically controlling for anger by regressing PTSD's items on an observed anger score. Individual factor loading differences were then compared to determine anger's underlying role. Results indicated that a significant amount of variance in PTSD, at both the item level and factor level, was attributable to an underlying dimension of anger. The largest factor attenuation was for the symptom of irritability/anger and the smallest attenuation was recklessness. The results suggest that anger underlies more of PTSD than the two diagnostic symptom criteria.

Occupational moral injury and mental health: systematic review and meta-analysis.

Many people confront potentially morally injurious experiences (PMIEs) in the course of their work which can violate deeply held moral values or beliefs, putting them at risk for psychological difficulties (e.g. post-traumatic stress disorder (PTSD), depression, etc.).AimsWe aimed to assess the effect of moral injury on mental health outcomes. We conducted a systematic review and meta-analysis to assess the association between work-related PMIEs and mental health disorders. Studies were independently assessed for methodological quality and potential moderator variables, including participant age, gender and PMIE factors, were also examined. Thirteen studies were included, representing 6373 participants. PMIEs accounted for 9.4% of the variance in PTSD, 5.2% of the variance in depression and 2.0% of the variance in suicidality. PMIEs were associated with more symptoms of anxiety and behavioural problems (e.g. hostility), although this relationship was not consistently significant. Moderator analyses indicated that methodological factors (e.g. PMIE measurement tool), demographic characteristics and PMIE variables (e.g. military v. non-military context) did not affect the association between a PMIE and mental health outcomes. Most studies examined occupational PMIEs in military samples and additional studies investigating the effect of PMIEs on civilians are needed. Given the limited number of high-quality studies available, only tentative conclusions about the association between exposure to PMIEs and mental health disorders can be made.Declaration of interestNone.

A relative weights comparison of trauma-related shame and guilt as predictors of DSM-5 posttraumatic stress disorder symptom severity among US veterans and military members.

Veterans and military service members have increased risk for post-traumatic stress disorder (PTSD) and consequent problems with health, psychosocial functioning, and quality of life. In this population and others, shame and guilt have emerged as contributors to PTSD, but there is a considerable need for research that precisely demonstrates how shame and guilt are associated with PTSD.This study examined whether a) trauma-related shame predicts PTSD severity beyond the effects of trauma-related guilt and b) shame accounts for a greater proportion of variance in PTSD symptoms than guilt. We collected cross-sectional self-report data on measures of PTSD symptom severity based on Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria, trauma-related shame, and trauma-related guilt via online survey. Participants included 61 US veterans and active duty service members. Hierarchical multiple regression and relative weights analysis were used to test hypotheses. In step 1 of regression analysis, guilt was significantly associated with PTSD.However, when shame was added to the model, the effect of guilt became non-significant, and only shame significant predicted PTSD.Results from relative weights analysis indicated that both shame and guilt predicted PTSD, jointly accounting for 46% of the variance in PTSD. Compared to guilt, trauma-related shame accounted for significantly more explained variance in PTSD. This study provided evidence that among US veterans and service members, trauma-related shame and guilt differ in their association with PTSD and that trauma-related shame, in particular, is associated with the severity of PTSD. Trauma-related shame and guilt explained almost half of the observed variance in PTSD symptom severity among this sample of US military veterans and service members. Trauma-related shame and guilt each made a unique contribution to PTSD severity after accounting for the similarity between these two emotions; however, shame was particularly associated with increased PTSD severity. These results highlight the importance of assessing and addressing trauma-related shame and guilt in PTSD treatment among military populations. We suggest that emotion- and compassion-focused techniques may be particularly relevant for addressing trauma-related shame and guilt. Limitations of the study Cross-sectional data does not allow for determination of causal relationships. Although sufficiently powered, the sample size is small. The present sample self-selected to participate in a study about stress and emotions.

Preschool Israeli Children Exposed to Rocket Attacks: Assessment, Risk, and Resilience.

Preschool children are among the most vulnerable populations to adversity. This study described the effects of 4 weeks of daily exposure to rocket attacks on children living on Israel's southern border. Participants enrolled in this study were 122 preschool children (50% boys) between the ages 3 and 6 years from 10 kindergartens. We assessed mothers' report of children's symptoms according to the DSM-IV and alternative criteria resembling the DSM-5 criteria for posttraumatic stress disorder (PTSD), general adaptation, traumatic exposure, and stressful life events 3 months after the war. The prevalence of PTSD was lower when the diagnosis was derived from the DSM-IV (4%) than from the DSM-5 criteria (14%). Mothers of children with 4 or more stressful life events reported more functional impairment in social, occupational, and other important areas of functioning compared to children with 0 or 1 stressful life event. Children with more severe exposure showed more severe symptoms and mothers had more concerns about the child's functioning (η(p)(2) = .09-.25). Stressful life events and exposure to traumatic experiences accounted for 32% of the variance in PTSD and 19% of the variance in the adaptation scale. Results were explored in terms of risk and resilience factors.

Trauma exposure and refugee status as predictors of mental health outcomes in treatment-seeking refugees.

Aims and method This study aimed to identify predictors of symptom severity for post-traumatic stress disorder (PTSD) and depression in asylum seekers and refugees referred to a specialised mental health centre. Trauma exposure (number and domain of event), refugee status and severity of PTSD and depression were assessed in 688 refugees.Results Symptom severity of PTSD and depression was significantly associated with lack of refugee status and accumulation of traumatic events. Four domains of traumatic events (human rights abuse, lack of necessities, traumatic loss, and separation from others) were not uniquely associated with symptom severity. All factors taken together explained 11% of variance in PTSD and depression.Clinical implications To account for multiple predictors of symptom severity including multiple traumatic events, treatment for traumatised refugees may need to be multimodal and enable the processing of multiple traumatic memories within a reasonable time-frame.

Traumatic dissociation as a predictor of posttraumatic stress disorder in South African female rape survivors.

Women survivors of rape are at an increased risk for posttraumatic stress disorder (PTSD). Traumatic dissociation has been identified as a precursor of PTSD. This study assessed the predictive potential of traumatic dissociation in PTSD and depression development.The study followed a longitudinal, prospective design. Ninety-seven female rape survivors were recruited from 2 clinics in Cape Town, South Africa. Clinical interviews and symptom status assessments of the participants were completed to measure dissociation, childhood traumas, resilience, depression, and PTSD.Traumatic dissociation was a significant predictor of PTSD and depression. The linear combination of prior dissociation, current dissociation, and resilience significantly explained 20.7% of the variance in PTSD. Dissociation mediated the relationship between resilience and PTSD.As traumatic dissociation significantly predicts PTSD, its early identification and management may reduce the risk of developing PTSD. Interventions focused on promoting resilience may also be successful in reducing the risk of dissociation following rape.

Patterns in Blame Attributions in Maltreated Youth: Association with Psychopathology and Interpersonal Functioning

This investigation explored patterns of blame attributions in 128 youth, primarily (87%) female, with maltreatment histories. Second, the study also evaluated the relative variance in posttraumatic stress disorder (PTSD) symptom severity, emotional distress, and interpersonal functioning outcomes, accounted for by age, abuse characteristics, and blame attribution patterns. Cluster analyses revealed distinctive blame profiles: high perpetrator blame, moderate perpetrator blame, high self-blame, high perpetrator/high self-blame, and low perpetrator/low self-blame. Regression analyses yielded significant models, accounting for 15% to 34% of the variance of outcomes. Most notably, youth endorsing a high perpetrator/high self-blame (i.e., compounded blame) attribution pattern reported poorer outcomes as compared to youth presenting with other blame profiles. Maltreatment type and age differences were not demonstrated across clusters. Implications and limitations are discussed.

Specific Trauma Subtypes Improve the Predictive Validity of the Harvard Trauma Questionnaire in Iraqi Refugees

Trauma exposure contributes to poor mental health among refugees, and exposure often is measured using a cumulative index of items from the Harvard Trauma Questionnaire (HTQ). Few studies, however, have asked whether trauma subtypes derived from the HTQ could be superior to this cumulative index in predicting mental health outcomes. A community sample of recently arrived Iraqi refugees (N = 298) completed the HTQ and measures of posttraumatic stress disorder (PTSD) and depression symptoms. Principal components analysis of HTQ items revealed a 5-component subtype model of trauma that accounted for more item variance than a 1-component solution. These trauma subtypes also accounted for more variance in PTSD and depression symptoms (12 and 10%, respectively) than did the cumulative trauma index (7 and 3%, respectively). Trauma subtypes provided more information than cumulative trauma in the prediction of negative mental health outcomes. Therefore, use of these subtypes may enhance the utility of the HTQ when assessing at-risk populations.
