Racial discrimination and posttraumatic stress: examining emotion dysregulation as a mediator in an African American community sample

The impact of trauma and how to intervene: a narrative review of psychotraumatology over the past 15 years

To mark 15 years of the European Journal of Psychotraumatology, editors reviewed the past 15-year years of research on trauma exposure and its consequences, as well as developments in (early) psychological, pharmacological and complementary interventions. In all sections of this paper, we provide perspectives on sex/gender aspects, life course trends, and cross-cultural/global and systemic societal contexts. Globally, the majority of people experience stressful events that may be characterized as traumatic. However, definitions of what is traumatic are not necessarily straightforward or universal. Traumatic events may have a wide range of transdiagnostic mental and physical health consequences, not limited to posttraumatic stress disorder (PTSD). Research on genetic, molecular, and neurobiological influences show promise for further understanding underlying risk and resilience for trauma-related consequences. Symptom presentation, prevalence, and course, in response to traumatic experiences, differ depending on individuals' age and developmental phase, sex/gender, sociocultural and environmental contexts, and systemic socio-political forces. Early interventions have the potential to prevent acute posttraumatic stress reactions from escalating to a PTSD diagnosis whether delivered in the golden hours or weeks after trauma. However, research on prevention is still scarce compared to treatment research where several evidence-based psychological, pharmacological and complementary/ integrative interventions exist, and novel forms of delivery have become available. Here, we focus on how best to address the range of negative health outcomes following trauma, how to serve individuals across the age spectrum, including the very young and old, and include considerations of sex/gender, ethnicity, and culture in diverse contexts, beyond Western, Educated, Industrialized, Rich, and Democratic (WEIRD) countries. We conclude with providing directions for future research aimed at improving the well-being of all people impacted by trauma around the world.

Are we gatekeeping trauma? A conceptual model to expand criterion A for invisible, identity-based, and systemic traumas

Since the inception of the criterion A framework into the posttraumatic stress disorder (PTSD) diagnosis in DSM-III, what qualifies as traumatic has been a fieldwide debate. Historically, social movements coinciding with advances in research have spurred improvements in the definition of criterion A, often by expanding the breadth of experiences that are considered trauma exposure. Contemporary issues of ongoing racial discrimination, ethno-violence, public health pandemics, warfare, oppression, and climate change warrant a re-examination of the criterion A definition. This critical review builds on prior critiques of criterion A and addresses (1) the limitations to the current criterion A definition in DSM-5 in capturing the experience of minoritized individuals; (2) three categories of trauma that are under-recognized in the current criterion A definition; and (3) the implications of expanding criterion A on clinical and research practice. We critically review three trauma categories that disproportionately affect minoritized individuals-invisible traumas, identity-based traumas, and systemic traumas. Evidence to date suggests that several traumatic experiences in these categories rise to the level of being traumatic, are associated with PTSD symptoms, and are prevalent among minoritized individuals. We discuss the implications of these traumas being omitted from criterion A and call for future work to critically examine the definition of criterion A in the PTSD diagnostic framework. Overall, this critical review captures traumas which remain undertreated, underdiagnosed, and under-represented by our current psychiatric nosology.

Investigating associations between emotion dysregulation and DSM-5 posttraumatic stress disorder (PTSD) using network analysis

Deficits in emotion regulation, termed emotion dysregulation, are critically linked to a range of psychiatric symptoms, including heightened risk for posttraumatic stress disorder (PTSD). Previous research suggests that effective emotion regulation can mitigate PTSD symptoms while emotion dysregulation may increase PTSD risk. Network analysis may be particularly useful for better understanding the co-occurrence of the two constructs because it provides insights into patterns of interconnections while accounting for the presence of each item in the network. The present study used network analysis to investigate the bridge associations between PTSD symptomology and dimensions of emotion dysregulation in a sample of 434 socioeconomically marginalized, trauma-exposed, primarily Black women (Mage = 41.65). Results of the network analysis revealed key nodes connecting PTSD and emotion dysregulation, identified lack of emotional clarity, impulse control difficulties, and difficulty engaging in goal-directed behavior among emotion dysregulation dimensions, and anhedonia, difficulty concentrating, and negative emotions among PTSD symptoms as having the highest bridge expected influence in the network. These findings offer insights into potential symptoms to target which may be valuable for reducing distress related to PTSD and co-occurring emotion dysregulation, emphasizing the importance of understanding the nuanced associations between these conditions to enhance clinical outcomes.

Research Agenda in Childhood Impairing Emotional Outbursts: A Report of the AACAP Presidential Taskforce on Emotional Dysregulation

Objective

As part of the 2019-2021 presidential term of the American Academy of Child and Adolescent Psychiatry (AACAP), the AACAP Presidential Initiative on Emotion Dysregulation in Youth Taskforce was established. The aim was to address emotion dysregulation in children and adolescents, focusing on developing methods for clinicians to identify, characterize, and treat impairing emotional outbursts along with development of a research agenda that would guide relevant researchers and research funders. One method to characterize emotion dysregulation was accomplished by recommendations for use of a diagnostic code that is available in the DSM. The research agenda is presented here.

Method

The Taskforce specifically focused on aggressive behaviors and emotions associated with outbursts. The development of a research agenda took place over 2 years of examination of the current needs in the literature, with contributions from experts in the field. This work dovetailed with the efforts from the Congress on Pediatric Irritability and Dysregulation, which had been meeting since 2015 to advance research into the measurement, pathophysiology, and treatment of emotion regulation problems in youth. We concentrated on the central questions concerning the measurement of outbursts, key questions linking outbursts to other psychopathologies, and how behavior in outbursts is separable from typical behavior.

Results

A description of the qualitative data gathering process is provided here, along with the following: recommendations in the research areas of measurement; pathophysiology; delineating outbursts from other psychopathologies; exploring the cultural, social, and interpersonal aspects of outbursts; understanding the prevention and treatment of outbursts; and exploring how outbursts manifest and are treated based on setting. Specific examples of research opportunities and future directions are provided.

Conclusion

A call is made to funding agencies to examine the spaces within their strategic plans that will allow for engagement in critical efforts to improve the lives of children and adolescents with severe emotional outbursts-some of the most impaired individuals presenting for care in child and adolescent psychiatry.

Discrimination Exposure, Neural Reactivity to Stress, and Psychological Distress

OBJECTIVE

Discrimination exposure has a detrimental impact on mental health, increasing the risk of depression, anxiety, and posttraumatic stress. The impact discrimination exposure has on mental health is likely mediated by neural processes associated with emotion expression and regulation. However, the specific neural processes that mediate the relationship between discrimination exposure and mental health remain to be determined. The present study investigated the relationship adolescent discrimination exposure has with stress-elicited brain activity and mental health symptoms in young adulthood.

METHODS

A total of 301 participants completed the Montreal Imaging Stress Task while functional MRI data were collected. Discrimination exposure was measured four times from ages 11 to 19, and stress-elicited brain activity and psychological distress (depression, anxiety, posttraumatic stress) were assessed in young adulthood (age 20).

RESULTS

Stress-elicited dorsolateral and dorsomedial prefrontal cortex (PFC), inferior parietal lobule (IPL), and hippocampal activity varied with discrimination exposure. Activity within these brain regions varied with the cumulative amount and trajectory of discrimination exposure across adolescence (initial exposure, change in exposure, and acceleration of exposure). Depression, anxiety, and posttraumatic stress symptoms varied with discrimination exposure. Stress-elicited activity within the dorsolateral PFC and the IPL statistically mediated the relationship between discrimination exposure and psychological distress.

CONCLUSIONS

The findings suggest that adolescent discrimination exposure may alter the neural response to future stressors (i.e., within regions associated with emotion expression and regulation), which may in turn modify susceptibility and resilience to psychological distress. Thus, differences in stress-elicited neural reactivity may represent an important neurobiological mechanism underlying discrimination-related mental health disparities.

Population-level normative models reveal race- and socioeconomic-related variability in cortical thickness of threat neurocircuitry

The inequitable distribution of economic resources and exposure to adversity between racial groups contributes to mental health disparities within the United States. Consideration of the potential neurodevelopmental consequences, however, has been limited particularly for neurocircuitry known to regulate the emotional response to threat. Characterizing the consequences of inequity on threat neurocircuitry is critical for robust and generalizable neurobiological models of psychiatric illness. Here we use data from the Adolescent Brain and Cognitive Development Study 4.0 release to investigate the contributions of individual and neighborhood-level economic resources and exposure to discrimination. We investigate the potential appearance of race-related differences using both standard methods and through population-level normative modeling. We show that, in a sample of white and Black adolescents, racial inequities in socioeconomic factors largely contribute to the appearance of race-related differences in cortical thickness of threat neurocircuitry. The race-related differences are preserved through the use of population-level models and such models also preserve associations between cortical thickness and specific socioeconomic factors. The present findings highlight that such socioeconomic inequities largely underlie race-related differences in brain morphology. The present findings provide important new insight for the generation of generalizable neurobiological models of psychiatric illness.

Moderating the link between discrimination and adverse mental health outcomes: Examining the protective effects of cognitive flexibility and emotion regulation

Discrimination is associated with mental health problems. While prior research has demonstrated the significance of emotion regulation in explaining the onset and development of discrimination-related anxiety, few studies investigated this dynamic with cognitive flexibility among sexual and/or racial minority individuals. The current study incorporated cognitive flexibility to investigate its potential buffering effects on discrimination-related anxiety. 221 individuals, 37.6% of whom (n = 83) identified as sexual and/or racial minorities, responded to an online questionnaire about their levels of cognitive flexibility and emotion regulation, perceived discrimination, and anxiety. Moderated mediation analyses were conducted with these variables. Our findings indicated that emotion regulation difficulty (ERD) mediated the relationship between discrimination and anxiety, while cognitive flexibility had a strong moderating effect on the relationship between ERD and anxiety. These results suggested new research directions and implied the therapeutic potential of advancing cognitive flexibility skills with emotion regulation training in depression and anxiety intervention and treatments. Future research is needed to investigate cognitive flexibility as a transdiagnostic mechanism underlying the onset and development of anxiety, to potentially lead to novel prevention or intervention for marginalized people facing additional stressors like discrimination.

Indirect Effects of Racial Discrimination on Health Outcomes Through Prefrontal Cortical White Matter Integrity

BACKGROUND

Racial discrimination is consistently associated with adverse health outcomes and has been linked to structural decrements in brain white matter. However, it is unclear whether discrimination-related neuroplastic changes could indirectly affect health outcomes. Our goal was to evaluate indirect associations of racial discrimination on health outcomes through white matter microstructure in a sample of trauma-exposed Black women.

METHODS

A trauma study in an urban hospital setting recruited 79 Black women who received a history and physical examination to assess medical disorders (compiled into a summed total of disorder types). Participants reported on experiences of racial discrimination and underwent diffusion tensor imaging; fractional anisotropy values were extracted from white matter pathways previously linked to racial discrimination (corpus callosum, including the body and genu; anterior cingulum bundle; and superior longitudinal fasciculus) and entered into mediational models.

RESULTS

Indirect effects of racial discrimination on medical disorders through left anterior cingulum bundle fractional anisotropy were significant (β = 0.07, SE = 0.04, 95% CI [0.003, 0.14]) after accounting for trauma and economic disadvantage. Indirect effects of racial discrimination on medical disorders through corpus callosum genu fractional anisotropy were also significant (β = 0.08, SE = 0.04, 95% CI [0.01, 0.16]).

CONCLUSIONS

Racial discrimination may increase risk for medical disorders via neuroplastic effects on microstructural integrity of stress-sensitive prefrontal white matter tracts. Racial discrimination-related changes in these tracts may affect health behaviors, which, in turn, influence vulnerability for medical disorders. These data highlight the connections between racial discrimination, prefrontal white matter connections, and incidence of medical disorders in Black Americans.

Racial discrimination, childhood adversity, and depression among Black men: Tests of stress sensitization hypotheses

Racial discrimination has been linked to depression among Black American men. Racial discrimination, however, does not uniformly confer risk for depression. According to the stress sensitization theory, racial discrimination can be particularly harmful for those with histories of adversity in childhood. Existing research on stress sensitization is limited in that it has conceptualized childhood adversity as a unidimensional construct composed of a broad range of stressful experiences. To fill this gap in the literature, the current study investigated stress sensitization hypotheses, focusing on how different dimensions of adverse childhood experiences moderate the association between racial discrimination and depression. Study sample was 504 young Black men (mean age at baseline = 20.3, SD = 1.08) living in rural counties in South Georgia where childhood adversity is disproportionately high. The association between racial discrimination and increased risk for depressive symptoms varied by the degree of childhood experience of deprivation, but not threat. Our findings suggest that no or low levels of childhood deprivation, which is commonly regarded as a protective factor, can elevate the negative effects of discrimination on depression. This finding emphasizes that clinicians should consider developmental risk and protective factors that are unique to Black American men.

Equity, diversity, and inclusion in developmental neuroscience: Practical lessons from community-based participatory research

Exclusion of racialized minorities in neuroscience directly harms communities and potentially leads to biased prevention and intervention approaches. As magnetic resonance imaging (MRI) and other neuroscientific techniques offer progressive insights into the neurobiological underpinnings of mental health research agendas, it is incumbent on us as researchers to pay careful attention to issues of diversity and representation as they apply in neuroscience research. Discussions around these issues are based largely on scholarly expert opinion without actually involving the community under study. In contrast, community-engaged approaches, specifically Community-Based Participatory Research (CBPR), actively involve the population of interest in the research process and require collaboration and trust between community partners and researchers. This paper outlines a community-engaged neuroscience approach for the development of our developmental neuroscience study on mental health outcomes in preadolescent Latina youth. We focus on "positionality" (the multiple social positions researchers and the community members hold) and "reflexivity" (the ways these positions affect the research process) as conceptual tools from social sciences and humanities. We propose that integrating two unique tools: a positionality map and Community Advisory Board (CAB) into a CBPR framework can counter the biases in human neuroscience research by making often invisible-or taken-for-granted power dynamics visible and bolstering equitable participation of diverse communities in scientific research. We discuss the benefits and challenges of incorporating a CBPR method in neuroscience research with an illustrative example of a CAB from our lab, and highlight key generalizable considerations in research design, implementation, and dissemination that we hope are useful for scholars wishing to take similar approaches.

Systematic Review: The Association Between Race-Related Stress and Trauma and Emotion Dysregulation in Youth of Color

OBJECTIVE

This systematic review aims to summarize the current state of knowledge on the relations between race-related stress and trauma (RST) and emotion dysregulation, synthesize empirical research examining these associations in youth of color, and discuss clinical implications.

METHOD

We searched PubMed, ProQuest PsycInfo, and Web of Science for relevant articles on June 24, 2021. Eligible studies were empirical studies in peer-reviewed journals or from gray literature. They included a sample of participants (5-24 years of age) from racial and ethnic minority backgrounds and at least 1 measure of RST and emotion dysregulation. We evaluated target studies using the Quality Assessment for Diverse Studies and extracted information on associations between RST and emotion dysregulation, as well as mediators and moderators.

RESULTS

Ultimately, 29 studies (78,173 participants) met inclusion criteria. A total of 28 studies were correlational, 16 were cross-sectional, and 12 were longitudinal. Greater RST was linked to greater emotion dysregulation in 78% of observed associations. Remaining associations were not significant. Relationships were mediated by types of coping, biological factors, and identity factors. RST was also related to several wellbeing outcomes through its relations with emotion dysregulation.

CONCLUSION

Results consistently demonstrated that greater exposure to RST is related to greater emotion dysregulation and decreased wellbeing in youth of color. These findings suggest that clinicians should incorporate the role of RST in case conceptualizations and treatment plans for this population. Future research should use multidimensional measures of RST and include experimental studies to examine the causal relationship between RST and emotion dysregulation.

An Examination of Discrimination on Stress, Depression, and Oppression-Based Trauma During the COVID-19 Pandemic and the Racial Awakening of 2020

Background

Discrimination is a pervasive societal issue that monumentally impacts people of color (POC). Many Black, Asian, and Hispanic/Latinx individuals report experiencing race-based discrimination in their lifetime. Discrimination has previously been linked to adverse health outcomes among POC, including stress, depressive, and posttraumatic stress disorder symptoms. These health disparities are posited to have become exacerbated by COVID-19 and the racial awakening of 2020. The current study examined the short- and long-term effects of discrimination on stress, depression, and oppression-based trauma among POC.

Methods

Participants were (n = 398) who identified as Black, Indigenous, Hispanic/Latinx, and Asian completed an online self-report survey assessing discrimination, depression, stress, and oppression-based trauma collected at 3 time points: (T1) beginning of the COVID-19 pandemic (May 2020), (T2) 6 weeks later during the racial awakening of 2020 (June 2020), (T3) one year later (June 2021).

Results

Significant positive paths were revealed from T1 discrimination to T2 depression, T2 stress, and T3 oppression-based trauma. The association between T1 discrimination and T3 oppression-based trauma was partially mediated by T2 depression, but not by stress; total and total indirect effects remained significant. The final model accounted for a significant proportion of the variance in T3 oppression-based trauma, T2 depression, and T2 stress.

Conclusion

Findings are consistent with prior research linking discriminatory experiences with mental health symptomatology and provide evidence that race-based discrimination poses harmful short-and long-term mental health consequences. Further research is necessary to better understand oppression-based trauma to improve the accuracy of clinical diagnosis and treatment of POC.

Experiencing racial discrimination increases vulnerability to PTSD after trauma via peritraumatic dissociation

Background: Racial discrimination is a traumatic stressor that increases the risk for posttraumatic stress disorder (PTSD), but mechanisms to explain this relationship remain unclear. Peritraumatic dissociation, the complex process of disorientation, depersonalization, and derealization during a trauma, has been a consistent predictor of PTSD. Experiences of frequent racial discrimination may increase the propensity for peritraumatic dissociation in the context of new traumatic experiences and contribute to PTSD symptoms. However, the role of peritraumatic dissociation in the relationship between experiences of discrimination and PTSD has not been specifically explored.Objective: The current study investigated the role of peritraumatic dissociation in the impact of racial discrimination on PTSD symptoms after a traumatic injury, and the moderating role of gender.Method: One hundred and thirteen Black/African American individuals were recruited from the Emergency Department at a Level I Trauma Center. Two weeks after the trauma, participants self-reported their experiences with racial discrimination and peritraumatic dissociation. At the six-month follow-up appointment, individuals underwent a clinical assessment of their PTSD symptoms.Results: Results of longitudinal mediation analyses showed that peritraumatic dissociation significantly mediated the effect of racial discrimination on PTSD symptoms, after controlling for age and lifetime trauma exposure. A secondary analysis was conducted to examine the moderating role of gender. Gender was not a significant moderator in the model.Conclusions: Findings show that racial discrimination functions as a stressor that impacts how individuals respond to other traumatic events. The novel results suggest a mechanism that explains the relationship between racial discrimination and PTSD symptoms. These findings highlight the need for community spaces where Black Americans can process racial trauma and reduce the propensity to detach from daily, painful realities. Results also show that clinical intervention post-trauma must consider Black Americans' experiences with racial discrimination.

Neural Impacts of Stigma, Racism, and Discrimination

Racism is a chronic stressor fueled by stigma that can result in significant distress and dysfunction as well as negatively affect emotions, behavior, quality of life, and brain health. The effects of stigma and discrimination emerge early in life and have long-term consequences. In this review, we sought to use neuroscience research to describe how stigma, racism, and discrimination can impact brain and mental health. Societal stigmas may be encoded by associative fear learning and pattern completion networks, and experiences of racial discrimination may similarly affect threat-responsive regions and circuits. Race-related differences in brain function and structure supporting threat circuitry are largely attenuated when negative life experiences and discrimination are taken into account. Downstream, chronic activation of the hypothalamic-pituitary-adrenal axis and the sympathetic-adrenal-medullary axis in the context of discrimination and stigma can contribute to physical health disparities in minoritized and marginalized groups. Finally, we discuss models that provide a framework for interventions and societal-level strategies across ecologic systems to build resilience and foster posttraumatic growth.

Identifying latent profiles of emotion dysregulation in a sample of primarily Black women with trauma exposure

BACKGROUND

Emotion dysregulation (ED) is a heterogenous, multi-dimensional transdiagnostic risk factor relevant to the development and maintenance of both internalizing and externalizing psychopathology, especially for those who have experienced trauma. The goals of the current study were to use person-centered analyses to identify distinct profiles of individuals characterized by unique patterns of ED dimensions, and to examine differences in internalizing and externalizing symptoms in a community sample.

METHODS

Participants (n = 783, 97% Black, 93% women) were recruited from an urban safety net hospital with high rates of trauma exposure. Latent profile analysis was used to uncover unique patterns of ED and multinomial logistic regression to evaluate the conditional distribution of our correlates across profiles.

RESULTS

The best-fitting model uncovered four classes: Low ED (42%), Low Awareness/Clarity (34%), Low Impulse Control (17%), and High ED (6%). All classes differed in terms of internalizing symptoms (anxiety sensitivity, depression, PTSD), with classes characterized by higher ED reporting more severe symptoms. For externalizing symptoms (food addiction behaviors, alcohol and drug abuse, aggressive behavior), the Low ED class reported fewer symptoms than all other profiles, while Low Awareness/Clarity, Low Impulse Control, and High ED did not differ from each other.

CONCLUSIONS

Patterns of emotion dysregulation ought to be assessed and considered as treatment targets for those experiencing both internalizing and externalizing psychopathology symptoms.

Racial discrimination associates with lower cingulate cortex thickness in trauma-exposed black women

Racial discrimination (RD) has been consistently linked to adverse brain health outcomes. These may be due in part to RD effects on neural networks involved with threat appraisal and regulation; RD has been linked to altered activity in the rostral anterior cingulate cortex (rACC) and structural decrements in the anterior cingulum bundle and hippocampus. In the present study, we examined associations of RD with cingulate, hippocampus and amygdala gray matter morphology in a sample of trauma-exposed Black women. Eighty-one Black women aged 19-62 years were recruited as part of an ongoing study of trauma. Participants completed assessments of RD, trauma exposure, and posttraumatic stress disorder (PTSD), and underwent T1-weighted anatomical imaging. Cortical thickness, surface area and gray matter volume were extracted from subregions of cingulate cortex, and gray matter volume was extracted from amygdala and hippocampus, and entered into partial correlation analyses that included RD and other socio-environmental variables. After correction for multiple comparisons and accounting for variance associated with other stressors and socio-environmental factors, participants with more RD exposure showed proportionally lower cortical thickness in the left rACC, caudal ACC, and posterior cingulate cortex (ps < = 0.01). These findings suggest that greater experiences of RD are linked to compromised cingulate gray matter thickness. In the context of earlier findings indicating that RD produces increased response in threat neurocircuitry, our data suggest that RD may increase vulnerability for brain health problems via cingulate cortex alterations. Further research is needed to elucidate biological mechanisms for these changes.

The Role of Discrimination Experiences in Postrape Adjustment Among Racial and Ethnic Minority Women

Although recent studies have linked discrimination frequency among Black and Latinx individuals to PTSD symptom severity, to our knowledge, these associations have yet to be examined among a diverse sample of recent rape survivors. The current secondary analysis of existing data examined the role of discrimination experiences in post-traumatic stress disorder (PTSD) symptoms, depression, and alcohol and drug problems among a racially and ethnically diverse sample of recent rape survivors. Participants were 139 Black (48.2%; n = 67), American Indian (18.7%; n = 26), Hispanic (15.1%; n = 21), and mixed race (17.3%; n = 24) girls and women age 15 or older who presented to the emergency department (ED) for a sexual assault forensic medical exam. They were randomly assigned to one of three intervention conditions, and completed a six-month postrape follow-up, including questions about mental health, substance use problems, and discrimination experiences. Regression analyses revealed that Black women experienced discrimination in significantly more situations and with greater frequency compared to American Indian and Hispanic women. Discrimination frequency was positively associated with PTSD and depression symptoms even after controlling for age, education, race, and intervention condition, but was not associated with alcohol or drug problems. Findings highlight the importance of attending to the heterogeneous experiences of discrimination among racial and ethnic minority women. Future work should adapt evidence-based early interventions to be maximally effective at combating both racial and sexual trauma exposures.

Characterization of Maternal Psychosocial Stress During Pregnancy: The Healthy Start Study

Objective

To capture multidimensional maternal psychosocial stress using responses from the Edinburgh Postnatal Depression Scale (EPDS) and Cohen's Perceived Stress Scale (PSS) administered during pregnancy, and to identify sociodemographic, biological, and health behavioral correlates of the stress domains.

Methods

Using data from 1,079 pregnant women, we implemented principal component analysis on EPDS and PSS responses and retained factors based on the Scree plot and Eigenvalues >1. We then used linear regression to identify perinatal correlates of each domain.

Results

We identified three stress domains: "Feeling Overwhelmed," "Anhedonia," and "Lack of Control," which accounted for 10.6% of variance in questionnaire responses. In multivariable analyses, household income ≤$70,000 (β = 0.21 confidence interval [95% CI: 0.05-0.39]), primiparity (0.36 [0.02-0.71]), inadequate (0.21 [0.04-0.39]) or excessive gestational weight gain (0.27 [0.11-0.42]), and Healthy Eating Index (HEI) score ≤57 (0.14 [0.00-0.28]) were associated with Feeling Overwhelmed. Older age (0.02 [0.00-0.03] per 1-year), Hispanic ethnicity (0.19 [0.00-0.38]), and HEI score ≤57 (0.15 [0.02-0.28]) were associated with Anhedonia. Non-Hispanic Black race/ethnicity (0.37 [0.10-0.63]), not having graduated from college (0.16 [-0.02 to 0.35]), having a partner born outside the United States (0.17 [-0.02 to 0.37]), household size of ≥5 persons (0.21 [-0.02 to 0.37]), receiving public assistance (0.18 [-0.02 to 0.37]), and prenatal smoking (0.32 [0.05-0.59]) were associated with Lack of Control.

Conclusions

Three domains of maternal psychosocial stress during pregnancy (Feeling Overwhelmed, Anhedonia, and Lack of Control) were differentially related to sociodemographic, biological, and health behavioral characteristics that may be targets for interventions to ameliorate stress in pregnant women.

Prevalence, Severity and Burden of Post-Traumatic Stress Disorder in Black Men and Women Across the Adult Life span

Objectives: To examine post-traumatic stress disorder (PTSD) among Black adults in younger, middle, and older ages. Methods: Using nationally representative data from the National Survey of American Life, we estimated lifetime and 12-month prevalence of PTSD in Black men and women ages 18-34, 35-49, and 50+. We determined PTSD persistence and severity by age group, then associations of PTSD with socio-economic status, chronic stress, and racial discrimination in middle age. Results: The lifetime prevalence of PTSD was higher in Black women/men ages 18-34 (prevalence=14.0%/6.3%) and 35-49 (12.8%/4.6%) versus 50 and older (8.7%/5.1%). Those ages 35-49 were more likely than younger/older Black adults to have severe interference in work, relationships, and activities domains. In middle age, PTSD was associated with unemployment, lower education, poverty, and stress in Black men, and unemployment, divorce, poverty, stress, and discrimination in Black women. Discussion: Black women experience a disproportionate burden of PTSD in middle age.

An examination of ACEs, the internalization of the Superwoman Schema, and mental health outcomes among Black adult women

Despite the growing literature on the mental health implications of adverse childhood events (ACEs), little empirical evidence considers the role of sociocultural scripts in Black women's experiences of trauma and mental health. Emerging scholarship suggests that gendered racial stereotypes, such as the Superwoman Schema, might worsen the impact of ACEs on the mental health outcomes of Black women in the U.S. To address this gap, we sought to examine relationships among Black women's exposure to ACEs, endorsement of the Superwoman Schema, and mental health outcomes. The current sample included 447 Black women (20-35 years old) who completed measures of adverse childhood events, Superwoman Schema endorsement, and mental health (stress, anxiety, and depression). ACEs and endorsement of the Superwoman Schema were associated with higher stress, anxiety, and depressive symptomology. Additionally, Black women who experienced more ACEs and felt a stronger obligation to present an image of strength indicated more stress. Black women who experienced more ACEs and had a stronger determination to succeed reported higher anxiety. These results offer further evidence of the role of the Superwoman Schema on Black women's mental health. The authors discuss future research directions and clinical implications regarding the interconnections among sociocultural scripts of Black womanhood and trauma experiences.

The impact of neighborhood context on telomere length: A systematic review

A growing body of research demonstrates the association between neighborhood context and health. The underlying biological mechanisms of this association are not fully understood. We conducted a systematic review of studies that investigated the association between neighborhood context and telomere length (TL), a DNA-protein complex that shortens after cell division. Short TL is linked to age-related diseases and may be impacted by chronic stress. Nineteen eligible articles identified through PubMed and Scopus met inclusion criteria. Results demonstrated inconsistent support for the relationship between neighborhood disadvantage and short TL. However, findings across several studies provide evidence for an inverse association between perceived neighborhood problems and TL, suggesting that TL may be an important factor in understanding health vulnerabilities associated specifically with negative perceptions of the neighborhood context.

Racial Discrimination and White Matter Microstructure in Trauma-Exposed Black Women

BACKGROUND

Experiences of racial discrimination are linked to a range of negative brain health outcomes, but little is known about how these experiences impact neural architecture, including white matter microstructure, which may partially mediate these outcomes. Our goal was to examine associations between racially discriminatory experiences and white matter structural integrity in a sample of Black American women.

METHODS

We recruited 116 Black American women as part of a long-standing study of trauma. Participants completed assessments of racial discrimination, trauma exposure, and posttraumatic stress disorder and underwent diffusion tensor imaging. Fractional anisotropy and mean diffusivity values were extracted from major white matter tracts throughout the brain.

RESULTS

Experiences of racial discrimination were associated with significantly lower fractional anisotropy in multiple white matter tracts, including the corpus callosum, cingulum, and superior longitudinal fasciculus (ps < .004), even after accounting for variance associated with trauma, posttraumatic stress disorder, and demographic- and scanner-related factors.

CONCLUSIONS

These findings suggest that experiences of racial discrimination are independently related to decrements in white matter microarchitecture throughout the brain. In individuals who have experienced other types of adversity, racial discrimination clearly has additive and distinctive deleterious effects on white matter structure. Our findings suggest a pathway through which racial discrimination can contribute to brain health disparities in Black Americans; the deleterious contributions of racial discrimination on the microstructure of major white matter pathways may increase vulnerability for the development of neurodegenerative disorders as well as the development of mental health problems.

Evaluating the Factor Structure of the Emotion Dysregulation Scale-Short (EDS-s): A Preliminary Study

Emotion dysregulation (ED) can be considered a psychopathological transdiagnostic dimension, the presence of which should be reliably screened in clinical settings. The aim of the current study was to validate the Italian version of the Emotion Dysregulation Scale-short (EDS-s), a brief self-report tool assessing emotion dysregulation, in a non-clinical sample of 1087 adults (768 women and 319 men). We also assessed its convergent validity with scales measuring binge eating and general psychopathology. Structural equation modeling suggested the fit of a one-factor model refined with correlations between the errors of three pairs of items (χ² = 255.56, df = 51, p < 0.001, RMSEA = 0.08, CFI = 0.94, TLI = 0.93, SRMR = 0.04). The EDS-s demonstrated satisfactory internal consistency (ordinal alpha = 0.94). Moreover, EDS-s scores partly explained the variance of both binge eating (0.35, p < 0.001) and general psychopathology (0.60, p < 0.001). In conclusion, the EDS-s can be considered to be a reliable and valid measure of ED.

The mediating role of emotion dysregulation in the association between trait mindfulness and PTSD symptoms among trauma-exposed adults

Objectives

Growing evidence of the effectiveness of mindfulness-based interventions for posttraumatic stress disorder (PTSD) warrants greater understanding of factors relevant to the relation between trait mindfulness and PTSD, such as emotion dysregulation (ED). The goal of this study was to examine associations between trait mindfulness, ED, and PTSD symptoms across two samples of trauma-exposed adults.

Methods

Participants for Sample 1 (n = 39, 90% women, 100% Black) and Sample 2 (n = 60, 100% women, 87% Black) were recruited from an urban hospital in the South. Trait mindfulness, ED, and PTSD were assessed.

Results

Across both samples, mindfulness and ED were significantly associated with overall PTSD severity (r = -.49 and r = -.42, ps = .001; r = .53 and r = .51, ps < .001, respectively) in the expected direction. In Sample 1, mindful nonjudgment and difficulty with emotion regulation strategies showed the strongest associations with overall PTSD severity as well as symptom clusters. In Sample 2, mindful acceptance and all ED dimensions (except non-awareness) showed strong associations with overall PTSD severity and particularly with negative cognitions and mood symptoms. In both samples, ED mediated the association between mindfulness and overall PTSD severity (Sample 1: ab = -.15, 95%CI [-.35, -.02]; Sample 2: ab = -.11, 95%CI [-.22, -.04]).

Conclusions

These findings demonstrate the important role of ED in the relation between trait mindfulness and PTSD symptoms among trauma-exposed adults. They highlight the value of examining ED as a mechanism of change in mindfulness-based interventions for PTSD.

Emotion dysregulation and dissociation contribute to decreased heart rate variability to an acute psychosocial stressor in trauma-exposed Black women

Reduced heart rate variability (HRV) in response to stress is a biomarker of emotion dysregulation (ED) and is related to posttraumatic stress disorder (PTSD), yet less is known about its role with dissociation in trauma-exposed adults. The goals of the current study were to examine unique patterns of associations between ED, dissociation, and PTSD with HRV at 15, 30, and 45 min (T1, T2, T3) following an acute psychosocial stressor task in a sample of 49 trauma-exposed, urban-dwelling Black women. Associations with baseline psychophysiology measures were also examined. ED and dissociation were assessed using self-report; PTSD was determined using a semi-structured interview. Heart rate (HR) and HRV, indexed with low frequency/high frequency (LF/HF) ratio and respiratory sinus arrhythmia (RSA), were measured with electrocardiogram recordings. ED and dissociation were positively correlated with LF/HF ratio at T3 (p < .05). There were no significant differences between individuals with PTSD versus those without PTSD in HR or HRV following acute stressor; PTSD diagnosis was related to higher HR at baseline. Latent growth modeling revealed that ED was associated with higher LF/HF ratio directly following acute stressor, while dissociation was associated with increase in LF/HF ratio over time. These findings demonstrate that ED is related to higher sympathetic reactivity for a prolonged period of time following stress exposure, while dissociation shows a delayed association with LF/HF ratio, suggesting a distinct impaired parasympathetic activation pattern exists for dissociation.
