Terror catastrophizing: association with anxiety, depression, and transgenerational effects.

Background & Objectives: Terror catastrophizing, defined as an ongoing fear of future terrorist attacks, is associated with a higher incidence of anxiety disorders, among other psychological impacts. However, previous studies examining terror catastrophizing's relationship to other mental health disorders are limited. The current study sought to determine if patients diagnosed with anxiety and depression would experience increased terror catastrophizing. Additionally, this study aimed to investigate whether parental terror catastrophizing increases children's internalizing symptoms.Design & Methods: Individuals were randomly drawn from the Danish Civil Registration System and invited to complete a series of questionnaires to measure terror catastrophizing tendency, lifetime parental trauma, and children's internalizing symptoms. In total, n = 4,175 invitees completed the survey of which 933 reported on a child between 6 and 18 years. Responses were analyzed using a generalized linear regression model.Results: Participants diagnosed with anxiety alone or comorbid with depression were more likely to experience symptoms of terror catastrophizing than undiagnosed participants (ß = 0.10, p < .001; ß = 0.07, p = .012). Furthermore, the parental tendency to catastrophize terror was associated with higher internalizing symptoms in children (ß = 0.09, p = .006), even after taking parental diagnoses, as well as lifetime and childhood trauma into account.Conclusion: The results can inform clinical practices to account for a patient's potential to exhibit increased terror catastrophizing tendencies or be more affected by traumatic events. Additionally, they can offer insights for designing novel preventative interventions for the whole family, due to the relation between parental tendencies for terror catastrophizing and the internalizing symptoms observed in children.

Diagnoses of comorbid anxiety and depression tend to have increased terror catastrophizing (TC); however, a sole anxiety diagnosis is associated with more TC, while sole depression is not.Informative for clinical practice to understand how patients with TC tendencies are more likely to be impacted by traumatic events.Parental TC symptoms are linked to internalizing symptoms in children; thus, this could inform the design of novel preventative interventions.

Peritraumatic Dissociation Partially Mediates the Influence of Lifetime Trauma Exposure on Prospective PTSD Symptoms.

Higher lifetime trauma exposure and increased peritraumatic dissociation (PD) are well-known predictors of Post-Traumatic Stress Disorder (PTSD) symptoms following new trauma (prospective PTSD symptoms). The interplay between those factors, however, is not well established. In this study, we aimed to assess whether PD mediates the influence of lifetime trauma exposure on prospective PTSD symptoms. A total of 387 adults visiting five emergency departments who had experienced a traumatic event within 72 hours completed baseline assessments on lifetime trauma exposure count and PD. PTSD symptoms were assessed 1 month later. Structural equation modeling was used to examine the mediation effect of PD in the relationship between lifetime trauma exposure count and 1-month PTSD symptoms. We found that PD mediated the association between lifetime trauma exposure count and 1-month PTSD symptoms, even after accounting for some confounders. However, the mediation was partial, accounting for 17.9% of the lifetime trauma exposure count's total effect. While this finding is significant, it also suggests that additional mechanisms beyond PD play a role in explaining the influence of higher lifetime trauma exposure on prospective PTSD symptoms. These findings provide valuable insights into the complex dynamics of PTSD development and call for further research to explore complementary factors and preventive strategies.

Lifetime Polyvictimization and Mental Health Outcomes in Women With vs Without Incarceration Histories: A Population-Based Latent Class Analysis.

We use latent class analysis, a life course framework, and information on the type, frequency, and timing of trauma exposure to identify distinct polytrauma groups in a national sample of women (AddHealth). We compare the identified polytrauma groups and their associations with mental health in adulthood in women with and without incarceration histories. A unique group with polyvictimization (neglect, physical, sexual) exposure in childhood by a caregiver in women with incarceration histories was not identified in women without incarceration histories. We find evidence of distinct associations between polytrauma groups and mental health and possibly, criminal justice involvement, in adulthood.

Adverse Childhood Experiences Predict the Phenome of Affective Disorders and These Effects Are Mediated by Staging, Neuroimmunotoxic and Growth Factor Profiles.

Adverse childhood experiences (ACEs) enhance pro-inflammatory and pro-oxidant responses. In affective disorders, recent precision nomothetic psychiatry studies disclosed new pathway phenotypes, including an ROI-reoccurrence of illness (ROI)-oxidative stress latent construct. The aim of the present study is to delineate a) whether ACEs sensitize the M1 macrophage, the T helper cells (Th)1, Th2, and Th17, the IRS (immune-inflammatory-responses system), the CIRS (compensatory immunoregulatory system), and the neuroimmunotoxic and growth factor (GF) profiles and whether they are associated with ROI and the phenome of affective disorders and b) the molecular pathways underpinning the effects of the ACEs. We collected supernatants of stimulated (5 µg/mL of PHA and 25 µg/mL of LPS) and unstimulated diluted whole blood in 20 healthy controls and 30 depressed patients and measured a panel of 27 cytokines/GF using a Luminex method. ACEs (comprising mental and physical trauma, mental neglect, domestic violence, family history of mental disease, and parent loss) are accompanied by the increased stimulated, but not unstimulated, production of M1, Th1, Th2, Th17, IRS, neuroimmunotoxic, and GF profiles and are strongly correlated with ROI and the phenome. A latent vector extracted from the ROI features (recurrent episodes and suicidal behaviors) and the IRS/neuroimmunotoxic/GF profiles explains 66.8% of the variance in the phenome and completely mediates the effects of ACEs on the phenome. Enrichment analysis showed that the ACE-associated sensitization of immune/GF profiles involves JAK-STAT, nuclear factor-κB, tumor necrosis factor-α, G-protein coupled receptor, PI3K/Akt/RAS/MAPK, and hypoxia signaling. In summary, the ACE-induced sensitization of immune pathways and secondary immune hits predicts the phenome of affective disorders.

The association between maternal lifetime interpersonal trauma experience and perceived mother-infant bonding.

BACKGROUND: Interpersonal traumas are common among expectant and new mothers and are found to have considerable impacts on women's mental health. These experiences may disrupt maternal perceptions of the mother-infant relationship, which is essential for healthy infant development, but findings are inconsistent. This study aims to explore associations between lifetime interpersonal traumas and their impact on self-reported mother-infant bonding. METHODS: Secondary data analysis of a representative cohort of 453 women attending at a South London maternity service. Lifetime interpersonal trauma experience and its association with self-reported mother-infant bonding (Postpartum Bonding Questionnaire) was assessed in uni- and multivariable linear regressions, the latter adjusted to account for antenatal depressive and posttraumatic symptoms, measured using the Edinburgh Postnatal Depression Scale and Posttraumatic Stress Disorder Scale, and key sociodemographic risk factors. RESULTS: Maternal lifetime trauma was not associated with perceived difficulties in mother-infant bonding at three months postnatal; however antenatal depressive symptoms, both with continuous EPDS score (0.33, 95% CI 0.17-0.50, p<0.001) and clinical cut-off ≥13 (4.26, 95% CI 2.02-6.49, p<0.001) were associated with self-reported bonding difficulties. LIMITATIONS: The composite trauma measurement did not allow for a comprehensive assessment of individual trauma types. CONCLUSIONS: There was no evidence for a link between maternal lifetime trauma experiences and self-reported bonding difficulties. However, an association between antenatal depressive symptoms and perceived postpartum bonding impairment was found. This highlights the importance of identification and treatment of depressive symptoms during pregnancy and offering women support in facilitating a positive mother-infant relationship.

Lifetime Trauma History and Cognitive Functioning in Major Depression and Their Role for Cognitive-Behavioral Therapy Outcome.

Background: While cognitive-behavioral therapy (CBT) is the gold-standard psychological treatment for major depression (MD), non-response and lacking stability of treatment gains are persistent issues. Potential factors influencing treatment outcome might be lifetime trauma history and possibly associated primarily prefrontal-cortex- and hippocampus-dependent cognitive alterations. Method: We investigated MD and healthy control participants with (MD+T+, n = 37; MD-T+, n = 39) and without lifetime trauma history (MD+T-, n = 26; MD-T-, n = 45) regarding working memory, interference susceptibility, conflict adaptation, and autobiographical memory specificity. Further, MD+T+ (n = 21) and MD+T- groups (n = 16) were re-examined after 25 CBT sessions, with MD-T- individuals (n = 34) invited in parallel in order to explore the stability of cognitive alterations and the predictive value of lifetime trauma history, cognitive functioning, and their interaction for treatment outcome. Results: On a cross-sectional level, MD+T+ showed the highest conflict adaptation, but MD+T- the lowest autobiographical memory specificity, while no group differences emerged for working memory and interference susceptibility. Clinical improvement did not differ between groups and cognitive functioning remained stable over CBT. Further, only a singular predictive association of forward digit span, but no other facets of baseline cognitive functioning, lifetime trauma history, or their interaction with treatment outcome emerged. Discussion: These results indicate differential roles of lifetime trauma history and psychopathology for cognitive functioning in MD, and add to the emerging literature on considering cognitive, next to clinical remission as a relevant treatment outcome.

Structural brain changes with lifetime trauma and re-experiencing symptoms is 5-HTTLPR genotype-dependent.

Background: Findings on structural brain alterations following trauma are inconsistent due probably to heterogeneity in imaging studies and population, clinical presentations, genetic vulnerability, and selection of controls. This study examines whether trauma and re-experiencing symptoms are associated with specific alterations in grey matter volumes and if this varies according to 5-HTTLPR genotype. Methods: Structural MRI was used to acquire anatomical scans from 377 community-dwelling older adults. Quantitative regional estimates of 22 subregional volumes were derived using FreeSurfer software. Lifetime trauma was assessed using the validated Watson's PTSD inventory, which evaluates the most severe trauma experienced according to DSM criteria. Analyses adjusted for age, sex, total brain volume, head injury, and comorbidities. Results: Of the 212 participants reporting lifetime trauma, 35.4% reported re-experiencing symptoms and for 1.9%, this was severe enough to meet criteria for full threshold PTSD. In participants with the SS 5-HTTLPR genotype only, re-experiencing symptoms were associated with smaller volumes in middle and superior temporal, frontal (lateral orbital, rostral and caudal middle) and parietal (precuneus, inferior and superior) regions. The trauma-exposed participants without re-experiencing symptoms were not significantly different from the non-trauma-exposed participants except for smaller precuneus and superior parietal region in traumatized participants and a larger amygdala in traumatized women specifically. Conclusions: In the non-clinical sample, lifetime trauma and re-experiencing symptoms were associated with smaller volume in prefrontal, temporal and parietal cortex subregions, and this varied according to serotonergic genetic vulnerability, 5-HTTLPR SS individuals being most susceptible.

Antecedentes: Los hallazgos sobre las alteraciones estructurales cerebrales luego del trauma son inconsistentes debido probablemente a heterogeneidad en los estudios de imagen y población, presentaciones clínicas, vulnerabilidad genética y selección de los controles. Este estudio examina si el trauma y los síntomas de reexperimentación están asociados con alteraciones específicas en los volúmenes de materia gris y si esto varía de acuerdo al genotipo 5-HTTLPR.Métodos: Se utilizó IMR estructural para adquirir mapeos anatómicos de 377 adultos mayores residentes en viviendas comunitarias. Se derivaron estimados regionales cuantitativos de 22 volúmenes sub-regionales usando el software FreeSurfer. Se evaluó trauma a través de la vida utilizando el inventario para TEPT validado de Watson, que evalúa el trauma más severo experimentado de acuerdo a criterios DSM. Se ajustaron los análisis por edad, sexo, volumen cerebral total, trauma encefálico y comorbilidades.Resultados: De los 212 participantes que reportaron trauma en la vida, un 35.4% reportó síntomas de reexperimentación y para el 1,9% fueron lo suficientemente severos para cumplir los criterios para el umbral completo del TEPT. Sólo en los participantes con el genotipo SS 5-HTTLPR, los síntomas de reexperimentación se asociaron con menores volúmenes en las regiones temporal media y superior, frontal (orbitolateral, rostral y caudal medial) y parietal (precúneo, inferior y superior). Los participantes expuestos a trauma sin síntomas de reexperimentación no variaron significativamente respecto a los no expuestos a trauma excepto por menor tamaño del precúneo y región superior parietal en los participantes traumatizados y un mayor tamaño de la amígdala específicamente en mujeres traumatizadas.Conclusiones: En una muestra no-clínica, el trauma a través de la vida y los síntomas de reexperimentación se asociaron con menor tamaño en sub-regiones corticales prefrontales, temporales y parietales, y esto varía de acuerdo a la vulnerabilidad genética serotoninérgica, siendo más susceptibles los individuos 5-HTTLPR SS.

Association between trauma exposure and mood trajectories in patients with mood disorders.

BACKGROUND: Trauma exposure is associated with the development of mood disorders and their phenotypic presentation. Cross-sectional associations between trauma exposure and mood disorders are well documented. Data on the association of trauma with longitudinal mood trajectories are lacking. We investigated the association between trauma exposure and weekly mood trajectories. METHOD: Mood disorder patients (N = 107; female = 81; mean age = 37.04 years), assessed for trauma exposure at baseline using the Childhood Trauma Questionnaire (CTQ) and Life Events Checklist (LEC), completed weekly telephonic mood assessments using the Quick Inventory of Depressive Symptomatology (QIDS) and Altman Self-Rating Mania scale (ASRM) over a 16 week period commencing at one week post-discharge from hospital. Associations between trauma exposure, severity of mood symptoms and mood trajectories were analysed using Pearson's correlations, LS Mean scores, F-statistics, and RMANOVA. RESULTS: Trauma exposure was persistently associated, albeit with some fluctuation in the strength of the association, with depressive symptomatology. Emotional abuse showed the most persistent association over time. Sexual abuse was minimally associated with depressive symptomatology. The severity of childhood trauma exposure was positively correlated with the severity of depressive symptoms. Lifetime traumatic events were significantly associated with mania scores, however there was no association between childhood trauma exposure and mania symptoms. CONCLUSION: Identification of both a history of childhood abuse and neglect and lifetime traumatic event exposure is important in the assessment and management of patients with mood disorders, as trauma can exert a persistent impact on depression trajectories and on symptom severity.

Prenatal cortisol modifies the association between maternal trauma history and child cognitive development in a sex-specific manner in an urban pregnancy cohort.

Women's experience of trauma may cause lifelong alterations in physiological stress regulation, which can be transmitted to offspring in utero. We investigated, in a prospective pregnancy cohort, associations among maternal lifetime interpersonal trauma (IPT) history, prenatal cortisol dysregulation, and children's memory domains. Sex-specific effects were also explored. Pregnant women were enrolled from Brigham & Women's Hospital and affiliated clinics near Boston, MA, in 2002-2007. IPT was assessed with the Revised Conflict Tactics Scale, short form. Salivary cortisol was measured at five time points on each of three days in one week at 29.0 ± 5.1 weeks gestation, and morning rise and diurnal slope were calculated. The Wide Range Assessment of Memory & Learning, 2nd Edition was administered at 6.5 ± 1.0 years and scores were generated for general memory and three sub-domains: verbal, visual, and attention/concentration. In total, 258 maternal-child dyads provided memory and IPT and/or cortisol data. IPT was positively associated with verbal memory in boys (ß ± SE: 4.6 ± 2.6) and inversely associated with visual memory score in girls (-6.5 ± 3.2). IPT did not predict prenatal cortisol, but prenatal cortisol modified the association between IPT history and child memory in varying coefficient models allowing for non-linear effect modification. The strongest evidence of interaction was for visual memory in boys: IPT history was associated with poorer visual memory only in those with flatter prenatal diurnal slope (interaction p = .005). Maternal lifetime IPT that leads to prenatal HPA dysregulation may have consequences for child memory, more so than either trauma or elevated cortisol alone. Boys may be more vulnerable to effects. Sex- and timing-specific effects require further investigation.

Trauma Exposure Among Women in the Pacific Rim.

PURPOSE: Healthcare professionals who provide services in the immediate or long-term aftermath of traumatic events need to understand the nature and frequency of traumatic events in the lives of women. However, research on trauma exposure in women has only recently begun to assess events other than intimate partner and sexual violence and has not supported direct statistical comparison of cross-national and cross-cultural data. The purpose of this descriptive, correlational study was to describe and compare trauma exposure prevalence and type in community-based samples of women in the United States, Colombia, and Hong Kong. DESIGN: Women were recruited through posted notices at community health sites, snowball sampling, and online advertisements (N = 576). The Life Stressor Checklist-Revised (total score range 0 to 30) was used to determine the type and prevalence of trauma exposure. Data were collected by native language members of the research team. METHODS: Descriptive statistics were used to summarize demographic characteristics and trauma exposure for the total sample and each community-based sample (location). Between-location differences were tested using Fisher's exact tests for categorical measures and general linear models with pairwise a posteriori least squares t-test for continuous measures. Responses to open-ended questions were translated and categorized. FINDINGS: Over 99% of women in the total sample reported at least one traumatic life event. The mean number of traumatic life events per participant was 7, ranging from 0 to 24. Although there was consistency in the most commonly reported trauma exposures across locations, the rates of specific events often differed. CONCLUSIONS: Historical, political, geographic, and cultural factors may explain differences in trauma exposure among women in the four locations studied. CLINICAL RELEVANCE: This study offers relevant knowledge for providers in diverse locations who provide services to women who have experienced traumatic events and provides evidence for the need for future research to further enhance knowledge of trauma exposure among women, and on the effects of trauma in women's lives.

Preliminary findings on lifetime trauma prevalence and PTSD symptoms among adolescents in Sarawak Malaysia.

OBJECTIVE: The objective of this study is to determine the prevalence of lifetime exposure to traumatic events and its relation to PTSD symptoms. METHODS: Participants were randomly selected from several schools located in the city of Kuching. There were 85 adolescents participating in this study, with ages ranging from 13 to 14 years old, of whom 31% (n=26) were males and 69% (n=59) females. The Child Posttraumatic Stress Index-Revised, The Harvard Trauma Questionnaire and a lifetime trauma checklist were used in this study. RESULTS: Results showed that 77.6% of participants were exposed to at least one lifetime trauma. The most frequently reported traumas were road accident (20.1%), death of a family member (19.7%), and almost drowning (10%). There was more indirect trauma than direct trauma exposure. Males were more likely to be involved in traumatic events than females. Results showed that 7.1% (6) exhibited PTSD symptoms. There was no significant difference in the mean score of CPTS-RI between genders and among ethnic groups. Total exposure to traumatic events was significantly correlated with PTSD symptoms. CONCLUSION: Findings suggest that number of lifetime traumatic events was quite high and multiple exposures to traumatic events were significantly related to PTSD symptoms.

Trauma Exposure and Axis I Psychopathology: A Co-twin Control Analysis in Norwegian Young Adults.

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.

Potentially traumatic events and serious life stressors are prospectively associated with frequency of doctor visits and overnight hospital visits.

OBJECTIVE: Cumulative lifetime exposure to potentially traumatic events and serious life stressors has been linked with both mental and physical health problems; however, less is known about the association between exposure to potentially traumatic events and serious life stressors with health care use. We investigated whether a higher number of potentially traumatic events and serious life stressors were prospectively associated with an increased number of doctor visits and nights spent in the hospital. METHODS: Participants were drawn from the Health and Retirement Study, a prospective and nationally representative study of adults aged 50+ in the United States (n=7168). We analyzed the data using a generalized linear model with a gamma distribution and log link. RESULTS: A higher number of potentially traumatic events and serious life stressors were associated with an increased number of doctor visits and nights spent in the hospital. On a 10-point scale, each additional potentially traumatic event or serious life stressor was associated with an 8% increase in doctor visits after controlling for sociodemographic factors (RR=1.08, 95% CI=1.06-1.11; p<.001). Each additional potentially traumatic event or serious life stressor was also associated with an 18% increase in the number of nights spent in the hospital after controlling for sociodemographic factors (RR=1.18, 95% CI=1.10-1.27; p<.001). CONCLUSION: Exposure to potentially traumatic events and serious life stressors is associated with increased doctor visits and nights spent in the hospital, which may have important implications for the current standard of care.

The Frequency and Impact of Exposure to Potentially Traumatic Events Over the Life Course.

We examined the frequency and impact of exposure to potentially traumatic events among a nonclinical sample of older adults (n = 3,575), a population typically underrepresented in epidemiological research concerning the prevalence of traumatic events. Current PTSD symptom severity and the centrality of events to identity were assessed for events nominated as currently most distressing. Approximately 90% of participants experienced one or more potentially traumatic events. Events that occurred with greater frequency early in the life course were associated with more severe PTSD symptoms compared to events that occurred with greater frequency during later decades. Early life traumas, however, were not more central to identity. Results underscore the differential impact of traumatic events experienced throughout the life course. We conclude with suggestions for further research concerning mechanisms that promote the persistence of post-traumatic stress related to early life traumas and empirical evaluation of psychotherapeutic treatments for older adults with PTSD.
