An investigation of the associations between trauma exposure, racial stereotypes, and racist beliefs.

OBJECTIVE: Given the concerning rise in hate crimes in recent years, it is critical to better understand factors associated with racist beliefs. As suggested by terror management theory (TMT), trauma exposure and posttraumatic stress symptoms (PTSS) may activate existential distress and anxiety, which may strengthen worldviews, including prejudiced beliefs (Greenberg & Kosloff, 2008; Weise et al., 2012). Although PTSS include negative alterations in beliefs about other people and the world, the connection between trauma and racist beliefs has not been investigated. There may also be key differences in terms of types of trauma exposure, such as interpersonal and noninterpersonal trauma, and racial beliefs. METHOD: The present study aimed to determine: (a) whether cumulative trauma exposure and PTSS are associated with endorsement of racist perceptions and stereotypes regarding Black people, and (b) if interpersonal trauma is more strongly tied to prejudiced and stereotyped beliefs than noninterpersonal trauma among 277 White undergraduates (Mage = 23.33, SD = 6.11; 76.4% female). RESULTS: Neither cumulative trauma nor PTSS were found to be related to elevated racist beliefs or positive or negative stereotypes. However, noninterpersonal trauma exposure was associated with stronger endorsement of racist beliefs and negative stereotypes (ηp² = .03, .01). Surprisingly, interpersonal trauma exposure corresponded with lower racist beliefs (ηp² = .02). CONCLUSIONS: Noninterpersonal trauma exposure may thus activate TMT and strengthen prejudiced ideology, whereas interpersonal traumatic experiences and PTSS may not. More research is needed to better understand how types of traumatic events may relate to the development of prejudiced beliefs. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Physical Health Outcomes of Trauma Exposure Across the Lifespan.

Trauma exposure and posttraumatic stress symptoms (PTSS) are established risk factors for poorer physical health. Prior work has focused on childhood adversities and PTSS in relation to physical health conditions, but trauma exposure over the lifespan has been overlooked. Further, the associations between trauma and PTSS and other physical health markers, such as diet and exercise, are less clear. Very little is known regarding how different trauma types (i.e., interpersonal, non-interpersonal), may be tied to aspects of physical health. To expand this area of research, this study aimed to: (a) examine the links between cumulative trauma and PTSS, and body mass index (BMI), diet, and exercise; and (b) investigate the relations between interpersonal and non-interpersonal trauma and these three health indices, while controlling for PTSS. Participants were 493 Midwestern University students (Mage = 23.87, standard deviation [SD] = 6.90, range = 18-63; 79.3% female; 57.4% White). Cumulative trauma corresponded with higher BMIs and less exercise use (B = 0.10; B = -0.09), while PTSS were unrelated. Conversely, PTSS were tied to greater consumption of added sugars (B = 0.11), and cumulative trauma was not linked with diet. Interpersonal and non-interpersonal traumas were not tied to BMI or exercise, although interpersonal trauma and PTSS were linked with greater sugar intake and non-interpersonal trauma was associated with fruit and vegetable consumption. Trauma exposure and PTSS may have complicated and distinct associations with physical health indices, such as BMI, diet, and exercise, and additional research is needed to further parse out these relations.

Types of community violence exposure and clinical outcomes: Evidence of differing associations among emerging adults.

OBJECTIVE: Community violence (CV) is an important public health concern. The literature has largely focused on CV exposure among higher-risk, urban youth, while the impact of CV on emerging adults in university settings remains poorly understood, even though this developmental period is associated with heightened risk. Much of the extant research has utilized a cumulative approach to study CV, thus, little is known about how different dimensions of CV (i.e., direct, witnessed, learned about) may be uniquely related to functioning. METHOD: The goals of this study were to: (a) examine the associations between cumulative CV and both adverse (i.e., posttraumatic stress symptoms [PTSS], anger, emotion dysregulation) and adaptive (i.e., resilience) clinical outcomes and (b) investigate the distinct ties between the three CV dimensions and these constructs. This study included 547 emerging adults from two universities that are located in two U.S. cities with high crime rates (Mage = 20.31, SD = 2.08, range = 18-28; 80.8% female; 57.8% white). RESULTS: Cumulative CV was related to higher levels of PTSS as well as resilience. For the specific CV dimensions, direct CV was positively linked with PTSS, anger, and emotion dysregulation, whereas witnessed CV inversely corresponded with emotion dysregulation and resilience. Learning about CV was unrelated to clinical outcomes. CONCLUSIONS: Students in high crime areas are at heightened risk for CV, which may contribute to both psychological difficulties and resilience. Findings signal the need to better understand how to foster resilience among emerging adults exposed to violence in their communities. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Revictimization Risk Factors Following Childhood Maltreatment: A Literature Review.

Revictimization research, to date, has primarily focused on sexual revictimization (i.e., child sexual abuse and adult sexual assault), which has resulted in a lack of understanding of trauma revictimization more generally. Specifically, it is unclear what factors are placing individuals with a history of child maltreatment (i.e., sexual abuse, physical abuse, and witnessing intimate partner violence [IPV]) at greater risk for subsequent adult victimization (i.e., sexual assault and IPV). Existing theoretical and empirical work on revictimization suggest that multiple risk factors are likely present within this framework (e.g., posttraumatic stress symptoms [PTSS], emotion dysregulation, and risk-taking behaviors). Prior research has suggested that PTSS are often linked with these other risk factors, and it is possible that the development of PTSS following child maltreatment may be related to the development or maintenance of additional factors that increase the likelihood of revictimization. The purpose of this review was to synthesize findings regarding risk factors that place maltreated individuals at greater risk for adult revictimization. Approximately 228 studies were identified following a thorough search of the peer-reviewed literature using multiple databases (PsycINFO, PILOTS, and Google Scholar). Each study was critically analyzed for relevance. The included studies were used in our review of prevalence, specific risk factors that have been identified, and unanswered questions in this literature. PTSS were noted to be particularly important in the revictimization framework, and thus, a novel model of revictimization was also proposed where PTSS are illustrated as being associated with the development and maintenance of other factors within the revictimization framework.

Attrition from pediatric trauma-focused cognitive behavioral therapy: A meta-analysis.

Trauma-focused cognitive behavioral therapy (TF-CBT) is one of the leading interventions for trauma-exposed children and adolescents and is associated with significant improvements in a variety of trauma-related symptoms. Nonetheless, attrition from TF-CBT is quite common, and children who do not receive the full intervention may continue to suffer from trauma-related symptoms. Rates of premature termination have varied across studies, and to date, no meta-analyses have been conducted regarding dropout from TF-CBT. The objective of the present study was to conduct a meta-analysis of the rates of attrition from TF-CBT, as well as review factors related to premature termination from this intervention. A total of 22 studies were available for inclusion in this meta-analysis. The prevalence of attrition was 33.9% (95% CI [26.2%, 42.5%]) from 2,059 children receiving TF-CBT. Clinician-rated attrition was 38.5%, and 17.5% did not receive an adequate dose of TF-CBT (e.g., 12+ sessions). Further, the study type was related to differing rates of dropout, with randomized controlled trials having a much lower attrition rate. Regarding risk factors for premature termination, the emerging literature suggests that a child's age, racial-ethnic minority status, and symptom levels may evince some ties to attrition. Caregiver, family, therapist, and treatment factors remain underexplored in relation to premature termination; however, preliminary work suggests that lack of caregiver attendance and difficulty in the child-therapist relationship may be related to attrition. A substantial number of children prematurely terminate from TF-CBT, underscoring the need to better prevent dropout.

The Role of Dimensions of Emotion Dysregulation Following Exposure to Maltreatment and Adult Victimization.

Child maltreatment is related to a host of negative consequences, including difficulties with emotion regulation (ER), posttraumatic stress symptoms (PTSS), and greater risk for revictimization. Yet, the literature has largely focused on sexual revictimization, while relations between maltreatment and other adult victimization types (e.g., intimate partner violence [IPV]) are less clear. Further, associations between emotion dysregulation and both child and adult trauma exposure have been identified, but aspects of dysregulation (i.e., nonacceptance of emotional responses, difficulties engaging in goal-directed behavior, impulsivity, lack of emotional awareness, limited access to ER strategies, and lack of emotional clarity) have received less attention. This study aimed to: (1) investigate the associations between maltreatment and adult victimization and the six ER dimensions while accounting for PTSS, and (2) determine whether there are indirect effects between maltreatment and adult victimization through each ER component. Seven hundred and forty-four undergraduates from two universities participated in the study (Mage = 21.48, SD = 4.12; 80.9% women; 56.2% white). Maltreatment and PTSS were directly linked with adult victimization (B = 0.14, B = 0.01, respectively). PTSS was inversely associated with each ER aspect (Bs = 0.02-0.10). Unexpectedly, neither maltreatment nor adult victimization was related to the ER dimensions, and no indirect effects were observed between maltreatment and adult victimization through emotion dysregulation. These findings suggest that specific components of emotion dysregulation may not be tied to trauma exposure outside of PTSS. Further, it may be that the ER dimensions are not differentially related to increased risk for adult victimization.

Relational Factors Associated With Posttraumatic Stress Among Emerging Adults of Color Exposed to Community Violence.

The relationship between trauma exposure and posttraumatic stress symptoms (PTSS) is well-documented, but less is known about factors that contribute to the expression of PTSS following community violence exposure, particularly among emerging adults of color. Utilizing the Person-Environment Interaction model (Slaug et al., 2018), this study examined the role of relational factors, specifically ethnic identity, community cohesion, and social support, associated with PTSS following exposure to community violence. Participants included 243 emerging adult university students of color (Mage = 20.27, SD = 1.95, 83.5% female). Linear regression analyses indicated that less frequent trauma exposure and greater perceived social support were related to lower PTSS. A significant interaction was also found between social support and exposure to community violence, such that at low levels of social support, individuals with more community violence exposure had the highest levels of PTSS. Regression and moderation analyses indicated that ethnic identity and community cohesion were not significantly associated with PTSS in this sample. Findings highlight the importance of incorporating social support strategies in treatments for PTSS following community violence exposure.

Relationships Between Childhood Interpersonal Trauma, Religious Coping, Post-traumatic Stress Symptoms, and Resilience.

Positive and negative religious coping strategies have been linked to symptom trajectories following adult interpersonal trauma. However, the interactions between childhood interpersonal trauma, religious coping, and psychological outcomes are less clear. This study examined whether aspects of religious coping moderated the associations between cumulative childhood interpersonal trauma and mental health outcomes, such as post-traumatic stress symptoms (PTSS) and resilience. Participants included 525 undergraduates from two universities (Mage = 20.04, SD = 1.71; range = 18-24; 57.7% White; 82.1% female). In both the positive and negative religious coping models, cumulative childhood interpersonal trauma was related to PTSS (b = 6.66; b = 6.10, respectively). While positive religious coping was not associated with PTSS (b = .01), it was linked to resilience (b = .69). Negative religious coping was significantly related to PTSS (b = .75) but not resilience (b = -.20). No significant interactions were identified between aspects of religious coping and cumulative childhood interpersonal trauma. While religious coping was directly related to both positive and negative mental health outcomes, it may not be associated with the relationships between childhood interpersonal trauma exposure and clinical outcomes. Such findings offer valuable information on malleable factors that may contribute to adaptive and maladaptive functioning following childhood adversity.

Child Sexual Abuse and Adult Sexual Assault among Emerging Adults: Exploring the Roles of Posttraumatic Stress Symptoms, Emotion Regulation, and Anger.

Child sexual abuse (CSA) has been previously linked with a risk for adult sexual assault (ASA) and posttraumatic stress symptoms (PTSS). Yet, the relations between CSA, ASA, and other psychological outcomes that may contribute to increased risk for ASA are less clear. This study aims to: 1) examine the links between CSA and ASA and potential risk factors (i.e., PTSS, emotion dysregulation, anger), 2) determine whether there are indirect effects between CSA and ASA through each factor, and 3) investigate whether there are indirect effects between CSA and ASA through the DSM-5 posttraumatic stress disorder (PTSD) symptom clusters. The sample included 567 undergraduates (Mage = 20.84, SD = 4.10; 81.1% women; 56.6% white) from two universities. Both CSA and ASA were related to PTSS, emotion dysregulation, and anger. There were indirect effects of CSA on ASA through PTSS and anger (B = .04, B = .01, respectively). CSA was associated with each of the PTSD symptom clusters, but only marked alterations in arousal and reactivity were linked with ASA (B = .01). The clusters had no indirect effects on the relation between CSA and ASA. These findings revealed several factors that may be linked with increased risk for sexual victimization.

Trauma Exposure, Posttraumatic Stress Disorder, and Aggression Among Civilian Females.

Trauma exposure and posttraumatic stress disorder (PTSD) have evinced ties to increased risk for aggressive behavior. However, very little information is known regarding the relations between trauma exposure, PTSD, and aggression among non-veteran women. Furthermore, research has not examined the associations between trauma exposure, PTSD symptoms, and aggression using the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) PTSD criteria. The primary aim of the current study was to investigate the relationships between trauma exposure, PTSD symptoms, and aggression among women. The secondary aim was to examine the specific PTSD symptom clusters in relation to indices of aggression. A total of 217 civilian, trauma-exposed female undergraduate students participated in the study (Mage = 24.30, SD = 6.83, 63.2% White). Higher levels of trauma exposure and PTSD symptoms corresponded with anger (b = .47, 95% CI = [0.11-0.83]; b = .11, 95% CI = [0.05-0.16], respectively) and verbal aggression (b = .50, 95% CI = [0.21-0.78]; b = .06, 95% CI = [0.01-0.10], respectively). PTSD symptoms, but not cumulative trauma exposure, was associated with hostility (b = .23, 95% CI = [0.14-0.59]), whereas physical aggression was only related to trauma exposure (b = .69, 95% CI = [0.31-1.06]). Furthermore, there was a significant indirect effect of cumulative trauma through PTSD symptoms on anger and verbal aggression (b = .15, 95% CI = [0.05-0.32]; b = .09, 95% CI = [0.02-0.20], respectively). Trauma-exposed civilian females with higher levels of PTSD symptoms may be at increased risk for several indices of aggressive behavior. Furthermore, PTSD symptoms may better account for some, but not all, aspects of aggression in trauma-exposed women.

Sexual Assault, Posttraumatic Stress Symptoms, and Indices of Aggression Among Women.

Sexual assault is associated with many adverse outcomes, including a higher risk for developing posttraumatic stress symptoms (PTSS). Although nonsexual trauma exposure has been linked to aggression, the associations between sexual assault and aggression are understudied. Further, the DSM-5 conceptualization of posttraumatic stress disorder (PTSD) includes a symptom related to aggression, and associations between symptom clusters and aggression with regard to the new criteria are underexplored. The present study aimed to (a) examine the relations between sexual assault and indices of aggression (i.e., physical/verbal aggression, anger, and hostility) after accounting for PTSS and (b) investigate PTSD symptom clusters in relation to aggression among 263 women (Mage = 29.03 years, SD = 11.71; 67.6% white). Path analysis revealed that sexual assault was unrelated to indices of aggression, ßs = .003-.08; however, PTSS was consistently linked with increased aggression, ßs = .22-.49. Results indicated specificity in the associations between the symptom clusters and aspects of aggression. Negative alterations in cognitions and mood corresponded with increased physical aggression, ß = .28, and hostility, ß = .38, and avoidance was related to verbal aggression, ß = .19. Hyperarousal was also tied to higher levels of anger, hostility, and verbal aggression, ßs = .21-.33. Nonetheless, lower levels of intrusion symptoms were associated with increased anger and hostility, ß = -.26. With regard to understanding women's risk for aggression, PTSS may be more relevant than sexual assault. Further, there may be specificity related to the type of PTSD symptoms and aspects of aggression.

The Prevalence of Sexual Revictimization: A Meta-Analytic Review.

The literature consistently demonstrates evidence that child sexual abuse survivors are at greater risk of victimization later in life than the general population. This phenomenon is called sexual revictimization. Although this finding is robust, there is a large amount of variability in the prevalence rates of revictimization demonstrated in the literature. The purpose of the present meta-analysis was to calculate an average prevalence rate of revictimization across the literature and to examine moderators that may potentially account for the observed variability. Based on a review of PsycINFO and PILOTS, 1,412 articles were identified and reviewed for inclusion. This process resulted in the inclusion of 80 studies, which contained 12,252 survivors of child sexual abuse. The mean prevalence of sexual revictimization across studies was 47.9% (95% confidence intervals [43.6%, 52.3%]), suggesting that almost half of child sexual abuse survivors are sexually victimized in the future. The present study failed to find support for any of the examined moderators. Potential explanations of and implications for the results are offered, including suggestions for therapists.

Analysis of volatile profiles of green Hawai'ian coffee beans damaged by the coffee berry borer (Hypothenemus hampei).

BACKGROUND: The coffee berry borer (CBB), Hypothenemus hampei, is the most destructive insect pest of coffee globally, causing significant losses in yield and leading to 'off' flavors in damaged beans. Automated headspace sampling (AHS) and gas chromatography-mass spectrometry (GC-MS) were used to investigate changes in the volatile profiles of CBB-damaged green coffee beans. Green coffee from three coffee farms on the island of Hawai'i were sorted into three levels of CBB damage: non-damaged, slightly damaged (1-2 pinholes/bean), and heavily damaged (> 2 pinholes/bean). RESULTS: Distinct differences were found between green coffee bean samples based on the amounts of eight prominent volatiles. The amount of CBB damage was particularly correlated with the amount of both hexanal and 2-pentylfuran. Principal component analysis showed clustering of non-damaged green beans, which did not overlap with the slightly or heavily damaged clusters. Good separation was also found between a mixture of 50% slightly damaged and non-damaged coffee. However, 20% slightly damaged and non-damaged coffee clusters showed strong overlap. CONCLUSION: Understanding the effects of CBB damage on coffee flavor profiles is critical to quality control for this valuable agricultural product. The results of this study show that the volatile profiles of green coffee beans vary with CBB damage. With specific volatile profiles for CBB-damaged coffee identified, coffee samples can be tested in the lab, or potentially on the farm or in coffee mills, to identify high levels of CBB damage that may lead to off flavors and a reduction in product quality and value. © 2018 Society of Chemical Industry.
