RESUMO

BACKGROUND: Borderline personality disorder is the prototypical disorder of emotion dysregulation. We have previously shown that borderline personality disorder patients are impaired in their capacity to engage cognitive reappraisal, a frequently-employed adaptive emotion regulation strategy. METHODS: Here we report on the efficacy of longitudinal training in cognitive reappraisal to enhance emotion regulation in borderline patients. Specifically, the training targeted psychological distancing, a reappraisal tactic whereby negative stimuli are viewed dispassionately as though experienced by an objective, impartial observer. At each of 5 sessions over 2 weeks, 22 borderline (14 Female) and 22 healthy control (13 Female) participants received training in psychological distancing and then completed a widely-used picture-based reappraisal task. Self-reported negative affect ratings and functional magnetic resonance imaging (fMRI) data were acquired at the first and fifth sessions. In addition to behavioral analyses, we performed whole-brain pattern expression analyses using independently-defined patterns for negative affect and cognitive reappraisal implementation for each session. RESULTS: Borderline patients showed a decrease in negative affect pattern expression following reappraisal training, reflecting a normalization in neural activity. They did not, however, show significant change in behavioral self-reports. CONCLUSIONS: To our knowledge, this study represents the first longitudinal fMRI examination of task-based cognitive reappraisal training. Using a brief, proof-of-concept design, the results suggest a potential role for reappraisal training in the treatment of borderline patients.

RESUMO

Social support, as perceived and experienced within one's social network, has been associated with greater well-being and favorable health outcomes. The transition to college marks a critical time in which social support not only strengthens interpersonal bonds, but also may help an individual discover and utilize various coping strategies to lower risks associated with negative emotions, which may result in better health and well-being. In the present study, we collected data from a large sample of undergraduate students (N = 376) and conducted preregistered analyses to examine links between students' perceived social support in residential college communities, patterns of emotion regulation strategy use, and multiple indicators of health and well-being. Overall, we found partial support for our hypotheses, with some associations between social support and patterns of emotion regulation strategy use, as well as associations between strategy use and health indicators. All results held when adjusting for participants' age and gender. Taken together, the present findings revealed reliable links between social network indicators, emotion regulation strategy use, and health. Future research can extend these findings by observing how these relationships unfold over time, to better understand how people manage their emotions by drawing on their personal networks.

RESUMO

PURPOSE: We investigated the prevalence of financial toxicity in a population undergoing hematopoietic cell transplantation (HCT) evaluation and measured its impact on post-transplant clinical and health-related quality-of-life outcomes. MATERIALS AND METHODS: This was a prospective study in patients undergoing evaluation for allogeneic HCT between January 1, 2018, and September 23, 2020, at a large academic medical center. Financial health was measured via a baseline survey and the comprehensive score for financial toxicity-functional assessment of chronic illness therapy (COST-FACIT) survey. The cohort was divided into three groups: none (grade 0), mild (grade 1), and moderate-high financial toxicity (grades 2-3). Health-related quality of life outcomes were measured at multiple time points. Multivariate logistic regression analysis evaluated factors associated with financial toxicity. Kaplan-Meier curves and log-rank tests was used to evaluate overall survival (OS) and nonrelapse survival. RESULTS: Of 245 patients evaluated for transplant, 176 (71.8%) completed both questionnaires (median age was 57 years, 63.1% were male, 72.2% were White, and 39.2% had myelodysplastic syndrome, 38.1% leukemia, and 13.6% lymphoma). At initial evaluation, 83 (47.2%) patients reported no financial toxicity, 51 (29.0%) with mild, and 42 (23.9%) with moderate-high financial toxicity. Patients with financial toxicity reported significant cost-cutting behaviors, including reduced spending on food or clothing, using their savings, or not filling a prescription because of costs (P < .0001). Quality of life was lower in patients with moderate-high financial toxicity at 6 months (P = .0007) and 1 year (P = .0075) after transplant. Older age (>62; odds ratio [OR], 0.33 [95% CI, 0.13 to 0.79]; P = .04) and income ≥$60,000 in US dollars (USD) (OR, 0.17 [95% CI, 0.08 to 0.38]; P < .0001) were associated with lower odds of financial toxicity. No association was noted between financial toxicity and selection for transplant, OS, or nonrelapse mortality. CONCLUSION: Financial toxicity was highly correlated with patient-reported changes in compensatory behavior, with notable impact on patient quality of life after transplant.

RESUMO

Background: Sexual assault and alcohol use are significant public health concerns, including for the United States (US) military. Although alcohol is a risk factor for military sexual assault (MSA), research on the extent of alcohol-involvement in MSAs has not been synthesised.Objective: Accordingly, this scoping review is a preliminary step in evaluating the existing literature on alcohol-involved MSAs among US service members and veterans, with the goals of quantifying the prevalence of alcohol-involved MSA, examining differences in victim versus perpetrator alcohol consumption, and identifying additional knowledge gaps.Method: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for Scoping Reviews, articles in this review were written in English, published in 1996 or later, reported statistics regarding alcohol-involved MSA, and included samples of US service members or veterans who experienced MSA during military service.Results: A total of 34 of 2436 articles identified met inclusion criteria. Studies often measured alcohol and drug use together. Rates of reported MSAs that involved the use of alcohol or alcohol/drugs ranged from 14% to 66.1% (M = 36.94%; Mdn = 37%) among servicemen and from 0% to 83% (M = 40.27%; Mdn = 41%) among servicewomen. Alcohol use was frequently reported in MSAs, and there is a dearth of information on critical event-level characteristics of alcohol-involved MSA. Additionally, studies used different definitions and measures of MSA and alcohol use, complicating comparisons across studies.Conclusion: The lack of event-level data, and inconsistencies in definitions, measures, and sexual assault timeframes across articles demonstrates that future research and data collection efforts require more event-level detail and consistent methodology to better understand the intersection of alcohol and MSA, which will ultimately inform MSA prevention and intervention efforts.

Furthermore, event-level data is needed including amount and timeframe of alcohol consumption, relationship between victim and perpetrator, location of alcohol consumption and military sexual assault, and whether the assault was opportunistic or facilitated, to inform military sexual assault prevention and intervention efforts in the military.

RESUMO

BACKGROUND: Emotion regulation plays a crucial role in well-being in everyday life. Effective emotion regulation depends upon adaptively matching a given strategy to a given situation. Recent research has begun to explore these interactions in the context of daily reports of perceived stress, affect, and emotion regulation strategy usage. To further understand these differences in strategy efficacy in an ecologically valid context, we examined responses to real world stressors in a young adult sample. METHODS: We surveyed a range of emotion regulation strategies, including two forms of cognitive reappraisal (i.e., reinterpretation, which involves cognitively reframing one's emotional responses, and psychological distancing, which involves adopting an objective, impartial perspective). Participants reported strategy usage, momentary perceived stress, and affect in response to multiple ecological momentary assessments over a period of 7 days. RESULTS: Analyses of links between strategy usage and affect revealed that rumination was significantly negatively associated with more positive affect ratings. Further, a significant interaction between momentary perceived stress and reinterpretation usage was observed on affect, such that reinterpretation was more adaptive during situations perceived as less stressful. CONCLUSION: These results provide further insight into the importance of situational context in determining the effectiveness of particular emotion regulation strategies.

RESUMO

In recent decades, a substantial volume of work has examined the neural mechanisms of cognitive reappraisal. Distancing and reinterpretation are two frequently used tactics through which reappraisal can be implemented. Theoretical frameworks and prior evidence have suggested that the specific tactic through which one employs reappraisal entails differential neural and psychological mechanisms. Thus, we were motivated to assess the neural mechanisms of this distinction by examining the overlap and differentiation exhibited by the neural correlates of distancing (specifically via objective appraisal) and reinterpretation. We analyzed 32 published functional magnetic resonance imaging (fMRI) studies in healthy adults using multilevel kernel density analysis. Results showed that distancing relative to reinterpretation uniquely recruited right bilateral dorsolateral PFC (DLPFC) and left posterior parietal cortex, previously associated with mentalizing, selective attention and working memory. Reinterpretation relative to distancing uniquely recruited left bilateral ventrolateral PFC (VLPFC), previously associated with response selection and inhibition. Further, distancing relative to reinterpretation was associated with greater prevalence of bilateral amygdala attenuation during reappraisal. Finally, a behavioral meta-analysis showed efficacy for both reappraisal tactics. These results are consistent with prior theoretical models for the functional neural architecture of reappraisal via distancing and reinterpretation and suggest potential future applications in region-of-interest specification and neural network analysis in studies focusing on specific reappraisal tactics.

RESUMO

Aedes albopictus is considered a potential vector of arboviruses in Colombia. Females and males naturally infected with dengue, Zika and chikungunya viruses have already been found in this country. We document the first record of Ae. albopictus in the Cordoba department, in North of Colombia. The finding was carried out during Ae. aegypti collection activities in the Ayapel, Montelibano, Planeta Rica, Pueblo Nuevo and Puerto Libertador municipalities. The entomological material was collected in water containers such as cement water tanks, tanks, bottles, tires, abandoned toilets, and plastic lids with natural water located in the intradomicile, peridomicile, and extra-domicile spaces of the homes. We collected 658 Ae. albopictus samples in the larva and pupa stages, and once these reached adulthood, we determined that 389 were female and 269 were male. This is the first record of the presence of Ae. albopictus in the Cordoba department.

RESUMO

Despite the high risk for sexual assault among adolescents, few sexual assault prevention programs designed for implementation in high schools have sustained rigorous evaluation. The present study sought to better understand the factors that influenced the implementation of Your Voice Your View (YVYV), a four-session sexual assault prevention program for 10th grade students, which includes a teacher "Lunch and Learn" training as well as a 4-week school-specific social norms poster campaign. Following program implementation, eight school partners (i.e., health teachers, guidance counselors, teachers, and principals) participated in an interview to provide feedback on the process of program implementation. The Consolidated Framework for Implementation Research was utilized to examine site-specific determinants of program implementation. Participants discussed the importance of the design quality and packaging of the program, as well as the relative advantage of offering students a violence prevention program led by an outside team, as opposed to teachers in the school. School partners highlighted the importance of intensive preplanning before implementation, clear communication between staff, the utility of engaging a specific champion to coordinate programming, and the utility of offering incentives for participation. Having resources to support implementation, a desire to address sexual violence in the school, and a positive classroom climate in which to administer the small-group sessions were seen as school-specific facilitators of program implementation. These findings can help to support the subsequent implementation of the YVYV program, as well as other sexual assault prevention programs in high schools.

RESUMO

The experience of sexual victimization may lead to increased threat-biased information processing, including increased perceptions of peer attitudes that condone sexual violence. The perception that peers generally condone sexual violence may in turn inhibit survivors of sexual violence from intervening to address risk for harm among their peers. To assess this possibility, the present study examined the direct and indirect association between sexual victimization by a romantic partner, perceived peer rape myth acceptance (RMA), perceived social barriers to bystander intervention, and bystander behaviors over 2-month follow-up in a sample of 843 high school students. Multiple regression path analyses revealed a sequence of positive associations between sexual victimization, perceived peer RMA, and perceived social barriers to bystander intervention, respectively. These direct associations to be significant among girls, but not boys, and revealed an additional negative direct association between perceived social barriers to bystander intervention and bystander behavior over 2-month follow-up among girls. Furthermore, sexual victimization was indirectly associated with decreased bystander behaviors among girls through perceived peer RMA and perceived social barriers to bystander intervention, respectively. Taken together, the current findings highlight the importance of addressing misperceptions of peer norms among survivors of sexual violence in bystander intervention programs.

RESUMO

Despite the exciting advancement of novel therapies, chronic graft-versus-host disease (cGVHD) remains the most common cause of non-relapse mortality after allogeneic hematopoietic stem cell transplantation (HCT). Frontline treatment of cGVHD involves systemic steroids, which are associated with significant morbidities. We previously found that inhibition of spleen tyrosine kinase (SYK) with fostamatinib preferentially eradicated aberrantly activated B cells in both ex vivo studies of cGVHD patient B cells, as well as in vivo mouse studies. These and other preclinical studies implicated hyper-reactive B-cell receptor signaling and increased SYK expression in the pathogenesis of cGVHD and compelled this first in-human allogeneic HCT clinical trial. We investigated the safety and efficacy of the oral SYK inhibitor, fostamatinib, for both the prevention and treatment of cGVHD. The primary objective was to evaluate the safety of fostamatinib and determine its maximum tolerated dose in the post-HCT setting. Secondary objectives included assessing the efficacy of fostamatinib in preventing and treating cGVHD, as well as examining alterations in B-cell compartments with treatment. This was a single-institution phase I clinical trial that evaluated the use of fostamatinib in allogeneic HCT patients before the development of cGVHD or at the time of steroid-refractory cGVHD (SR-cGVHD). Patients received fostamatinib at one of three dose levels using a continual reassessment algorithm to determine the maximum tolerated dose. Multiparameter flow cytometry was used to evaluate changes in B cell subpopulations over the first year of treatment with fostamatinib. Nineteen patients were enrolled in this phase I trial, with 5 in the prophylaxis arm and 14 in the therapeutic arm. One patient (5%) required discontinuation of therapy for a dose-limiting toxicity. At a median follow-up of over 3 years, no patients had cancer relapse while on fostamatinib treatment, and recurrent malignancy was observed in 1 patient 2 years after the end of therapy. In the prophylaxis arm, 1 of 5 patients (20%) developed cGVHD while on fostamatinib. In the therapeutic arm, the overall response rate was 77%, with a complete response rate of 31%. The median duration of response was 19.3 months and the 12-month failure-free survival was 69% (95% confidence interval, 48-100). Patients were able to reduce their steroid dose by a median of 80%, with 73% remaining on a lower dose at 1 year compared to baseline. There was an early reduction in the proportion of IgD-CD38hi plasmablast-like cells with fostamatinib treatment, particularly in those SR-cGVHD patients who had an eventual response. B-cell reconstitution was not significantly impacted by fostamatinib therapy after allogeneic HCT. Fostamatinib featured a favorable safety profile in the post-HCT setting. Our data suggests an early efficacy signal that was associated with effects on expected cell targets in both the prophylaxis and treatment of cGVHD, providing rationale for a phase II investigation.

RESUMO

The current study sought to characterize commentary regarding intimate partner violence during the COVID-19 (SARS-CoV-2) pandemic via the Twitter hashtags #DomesticAbuse and #DomesticViolence. A sample of 481 original, English-language tweets containing the hashtag #DomesticAbuse or #DomesticViolence posted across five consecutive weekdays from March 22 to March 27, 2020-during which many places were enacting lockdown mandates-was examined using thematic content analyses. Overall, Twitter users commented on potential increased rates of IPV, while adding details about abuse tactics that could be employed by perpetrators during the pandemic. Additionally, Twitter users disclosed personal experiences of IPV victimization. Four themes were identified, including (1) type of domestic violence (i.e. whether the violence was COVID-specific or general domestic violence), (2) commentary about IPV (i.e. general reflections, decentralizing and centralizing survivorhood), (3) perpetrator tactic (i.e. abuse tactic used by the perpetrator), and (4) institutions responsible (i.e. institutions responsible for providing services to survivors). Overall, the commentary on Twitter reflected an effort to raise awareness and share informational aid for potential victims/survivors of IPV. Data highlight the potential of social media networks in conveniently facilitating the sharing and spreading of useful resources to other users. Future research should examine whether resources shared via Twitter reach individuals who need them and empower individuals to garner support.

RESUMO

Despite the widespread emergence of memory effects in solid systems, understanding the basic microscopic mechanisms that trigger them is still puzzling. We report how ingredients of solid state transport in polycrystalline systems, such as semiconductor oxides, become sufficient conditions for a memristive response that points to the natural emergence of memory, discernible under an adequate set of driving inputs. The experimental confirmation of these trends will be presented along with a compact analytical theoretical picture that allows discerning the relative contribution of the main building blocks of memory and the effect of temperature, in particular. These findings can be extended to a vast universe of materials and devices, providing a unified physical explanation for a wide class of resistive memories and pinpointing the optimal driving configurations for their operation.

RESUMO

Allogeneic hematopoietic stem cell transplantation (HCT) is a potentially curative treatment for both malignant and nonmalignant hematologic diseases; however, reported rates of treatment-related mortality approach 30%. Outcomes are worse in patients who begin HCT with functional impairments. To detect such impairments, a geriatric assessment (GA) is recommended in adults age ≥65 years. Younger HCT candidates also may be impaired because of chemotherapy regimens pre-HCT. Therefore, we hypothesized that GA can be beneficial for adult patients of all ages and subsequently created a clinical pretransplantation optimization program to assess all HCT candidates using a modified GA. One-hundred fifty-seven patients were evaluated in 4 functional domains- physical, cognitive, nutritional, and psychological-at 2 time points prior to HCT-new patient evaluation (NPE) and sign-off (SO)-between October 2017 and January 2020. At NPE, 80.9% of the patients had at least 1 domain with a functional impairment, and physical (P = .006), cognitive (P = .04), and psychological (P = .04) impairments were associated with an increased likelihood of not proceeding to HCT. In addition, patients age 18 to 39 years were more likely than older patients to have a physical function impairment (P = .001). Between NPE and SO, 51.9% of the patients had resolution of 1 or more impairments, and nutritional impairment at SO was predictive of worse overall survival (P = .01). Our study shows that GA can identify functional impairments in patients of all ages. Early identification of impairments could facilitate referrals to supportive care and resolution of impairments prior to HCT, suggesting that GA could be recommended for HCT candidates of all ages.

RESUMO

Resonant tunneling diode photodetectors appear to be promising architectures with a simple design for mid-infrared sensing operations at room temperature. We fabricated resonant tunneling devices with GaInAsSb absorbers that allow operation in the 2-4 µm range with significant electrical responsivity of 0.97 A/W at 2004 nm to optical readout. This paper characterizes the photosensor response contrasting different operational regimes and offering a comprehensive theoretical analysis of the main physical ingredients that rule the sensor functionalities and affect its performance. We demonstrate how the drift, accumulation, and escape efficiencies of photogenerated carriers influence the electrostatic modulation of the sensor's electrical response and how they allow controlling the device's sensing abilities.

RESUMO

The extended focused assessment of trauma (EFAST) examination is an invaluable tool for the initial evaluation of the trauma patient. Miniaturization of ultrasound has enabled helicopter emergency medical services (HEMS) to use point-of-care ultrasound to care for trauma patients on scene. Our study demonstrated that HEMS crews accurately performed EFAST examinations after the implementation of a novel HEMS EFAST workflow, multifaceted training, and ongoing quality assurance. The HEMS crews' overall sensitivity was 53%, and specificity was 98%. The obtained image quality was highest for the lung, cardiac, and right upper quadrant components of the EFAST. Our results suggest that with a structured multifaceted training program, user-friendly workflow, and ongoing quality assurance, HEMS crews can perform EFAST examinations safely and reliably in the field. This would allow HEMS crews to detect life-threatening, time-sensitive conditions such as a pneumothorax, pericardial effusion, and intraperitoneal hemorrhage. HEMS EFAST has the potential to triage certain trauma patients directly to the operating room or newly emerging hybrid suites, bypassing the emergency room and saving crucial time.

RESUMO

INTRODUCTION: Craving is an important contributing factor in cigarette smoking and has been added as a diagnostic criterion for addiction in the DSM-5. Cognitive-behavioral therapy and other treatments that incorporate craving regulation strategies reduce smoking and the likelihood of relapse. Although this finding suggests that the regulation of craving is an important mechanism underlying smoking cessation, whether targeted interventions that train smokers to regulate craving can directly impact real-world smoking behaviors is unclear. METHOD: Across two pilot studies (N = 33; N = 60), we tested whether a brief, computer-delivered training session in the cognitive regulation of craving altered subsequent smoking behaviors in daily life. The study first randomly assigned participants to either a no training (control) group, or one of two Regulation of Craving Training (ROC-T) conditions. Next, all participants came into the lab and those assigned to ROC-T conditions were trained to implement a cognitive strategy to regulate their craving, by either focusing on the negative consequences of smoking, or by distracting themselves. Then, these participants underwent ROC-T during which they practiced using the strategy to regulate their craving during cue exposure. The study subsequently assessed participants' smoking via daily diaries for 3-6 days, and via self-report up to 1-month follow-up. RESULTS: Across both studies, ROC-T conditions were associated with significant reductions in average cigarettes smoked per day, with effects persisting through follow-up. CONCLUSION: These results confirm that the regulation of craving is an important mechanism of smoking cessation, and can be targeted via easily administered training procedures, such as ROC-T.

RESUMO

Patients undergoing allogeneic (allo) and autologous (auto) hematopoietic cell transplantation (HCT) require extensive hospitalizations or daily clinic visits for the duration of their transplantation. Home HCT, wherein patients live at home and providers make daily trips to the patient's residence to perform assessments and deliver any necessary interventions, may enhance patient quality of life and improve outcomes. We conducted the first study of home HCT in the United States to evaluate this model in the US healthcare setting and to determine the effect on clinical outcomes and quality of life. This case-control study evaluated patients who received home HCT at Duke University in Durham, North Carolina, from November 2012 to March 2018. Each home HCT patient was matched with 2 controls from the same institution who had received standard treatment based on age, disease, and type of transplant for outcomes comparison. Clinical outcomes were abstracted from electronic health records, and quality of life was assessed via Functional Assessment of Cancer Therapy-Bone Marrow Transplant. Clinical outcomes were compared with Student's t-test or Fisher's exact test (continuous variables) or chi-square test (categorical variables). Quality of life scores were compared using the Student t-test. All analyses used a significance threshold of 0.05. Twenty-five patients received home HCT, including 8 allos and 17 autos. Clinical outcomes were not significantly different between the home HCT patients and their matched controls; home HCT patients had decreased incidence of relapse within 1 year of transplantation. Pre-HCT quality of life was well preserved for autologous home HCT patients. This Phase I study demonstrated that home HCT can be successfully implemented in the United States. There was no evidence that home HCT outcomes were inferior to standard-of-care treatment, and patients undergoing autologous home HCT were able to maintain their quality of life. A Phase II randomized trial of home versus standard HCT is currently underway to better compare outcomes and costs.

RESUMO

Hematopoietic cell transplant (HCT) is an increasingly common and curative treatment strategy to improve survival among individuals with malignant and nonmalignant diseases, with over one million HCTs having been performed worldwide. Neurocognitive dysfunction is a common and untoward consequence of HCT for many recipients, although few studies have examined the profile of neurocognitive impairments in HCT or their association with clinical features, such as frailty, or the incidence of pre-HCT neurocognitive impairments across all ages, which may influence post-HCT neurocognitive impairments. We examined the pattern and correlates of pre-transplant neurocognitive dysfunction in a prospective sample of adults undergoing HCT. Neurocognition was assessed using the Montreal Cognitive Assessment Battery. Frailty was assessed using the Short Physical Performance Battery. Linear regression analysis was used to examine the associations between neurocognitive performance and frailty. Neurocognitive screening profiles were also examined by partitioning MoCA into domain scores, including Executive Function and Memory. We also examined the associations between neurocognition, frailty, and clinical outcomes, including length of transplant hospitalization and survival. One hundred and ten adults were evaluated across a wide age range (range: 19-75; mean age = 54.7 [SD = 14.1]). Neurocognitive performance tended to fall below published normative levels (mean MoCA = 25.5 [SD = 4.1]), with 17% of participants demonstrating impaired performance compared with medical normative data (MoCA ≤ 22) and 34% exhibiting impaired performance relative to healthy samples (MoCA ≤ 25). Mild impairments (MoCA ≤ 25) were common across age ranges, including middle-aged patients (23% for age < 50; 35% for age 50-60, 41% for age ≥ 60), particularly for items assessing Executive Function. Greater levels of frailty associated with lower neurocognitive screening scores (r = -0.29, P < 0.01) and Executive Functioning (r = -0.24, P < 0.01), whereas greater age was associated with poorer Memory performance only (r = -0.33, P < 0.01). Greater levels of frailty prior to transplant associated with longer length of stay (ß = 0.10, P = 0.046), but were not associated with survival. Neurocognitive impairments are common among adults undergoing HCT and the pattern of performance varies by age. Pre-transplant frailty is associated with neurocognitive functioning and may portend worse post-transplant early clinical outcomes.

RESUMO

Although college students who are sexual and gender minorities (SGM) experience higher rates of sexual victimization than their peers who identify as heterosexual and cisgender, there is a paucity in the literature investigating how college campuses can address the needs of SGM college students in violence prevention and response. The present research examines a subset of data from the Healthy Minds Survey (HMS), a national web-based survey administered across two universities from 2016 to 2017. We examined the role of SGM status in the rates of sexual violence, perceptions of their college/university's institutional response to reports of sexual violence (e.g., taking a report seriously and taking corrective action), and the perceived impact of reporting sexual violence (e.g., students would support the person making a report). Logistic regression analyses revealed higher rates of sexual victimization among sexual minority students (compared to heterosexual), women (compared to men), and transgender and gender diverse (TGD) students (compared to cisgender). In addition, sexual minority (compared to heterosexual), women (compared to men), and TGD (compared to cisgender) students were more likely to perceive their institution would have a poor response to reports of sexual violence. Women and sexual minority students were also likely to believe that students who report sexual violence would suffer academically. These findings highlight the need for continued efforts to enhance sexual assault prevention and response efforts on college campuses, especially for SGM students.
