RESUMO
OBJECTIVE: Chronic pain often co-occurs with posttraumatic stress disorder (PTSD). The mutual maintenance hypothesis proposes that there may be shared underlying mechanisms of symptoms of pain exacerbating PTSD, and vice versa. The association between PTSD and pain intensity remains understudied. To elucidate the relationship, the present study examined the temporality of changes in PTSD severity and pain intensity in veterans undergoing intensive PTSD treatment. METHOD: Data from 332 veterans undergoing intensive 2-week cognitive processing therapy- (CPT-) based treatment (ITP) with adjunctive components (i.e., mindfulness, art therapy). Random intercepts cross-lagged panel models (RI-CLPMs) were used to examine within-subjects relationships between pain intensity and PTSD severity over the course of the program. RESULTS: Veterans experienced large PTSD severity reductions (Essg = 1.20; p < .001) and small pain severity reductions (Essg = 0.21; p < .001) over the course of treatment, despite pain not being a treatment target. RI-CLPMs revealed that PTSD severity significantly predicted subsequent pain severity. Results indicate the absence of a bidirectional relationship in that changes in pain intensity did not predict later PTSD severity improvement during the ITP. Time trends for both PTSD severity and pain intensity were generally consistent with respect to baseline demographic characteristics. CONCLUSION: Our findings support the mutual maintenance regarding the association between PTSD and pain intensity. Future research should investigate temporal associations in other evidence-based PTSD treatments and formats and evaluate the long-term impacts of PTSD treatment on pain intensity.

RESUMO
RNA-binding proteins (RBPs) are emerging as important regulators of cancer pathogenesis. We reveal that the RBPs LARP4A and LARP4B are differentially overexpressed in osteosarcoma and osteosarcoma lung metastases, as well as in prostate cancer. Depletion of LARP4A and LARP4B reduced tumor growth and metastatic spread in xenografts, as well as inhibiting cell proliferation, motility, and migration. Transcriptomic profiling and high-content multiparametric analyses unveiled a central role for LARP4B, but not LARP4A, in regulating cell cycle progression in osteosarcoma and prostate cancer cells, potentially through modulating key cell cycle proteins such as Cyclins B1 and E2, Aurora B, and E2F1. This first systematic comparison between LARP4A and LARP4B assigns new pro-tumorigenic functions to LARP4A and LARP4B in bone and prostate cancer, highlighting their similarities while also indicating distinct functional differences. Uncovering clear biological roles for these paralogous proteins provides new avenues for identifying tissue-specific targets and potential druggable intervention.
RESUMO
This practitioner narrative describes the development of an innovative, primary and secondary prevention resource to provide confidential resources to youth with questions about potentially problematic sexual interests and behaviors. WhatsOK is a website and free confidential helpline for youth who are potentially at risk to sexually harm or have harmed someone in the past. By encouraging self-efficacy, helpline counselors respond to these inquires in order to prevent harmful events or lessen the impact. This practitioner narrative begins with an explanation of the planning process, then describes the implementation, piloting and refining the resource, and, finally, explains how evaluation was incorporated. The development of the WhatsOK helpline services was conducted with the goal of creating an evidence-informed resource for youth with concerns about sexual thoughts and behaviors.

Recent developments have mounted a stunning body of evidence underlying the importance of RNA binding proteins (RBPs) in cancer research. In this minireview we focus on LARP4A and LARP4B, two paralogs belonging to the superfamily of La-related proteins, and provide a critical overview of current research, including their roles in cancer pathogenesis and cell proliferation, migration, cell cycle and apoptosis. We highlight current controversies surrounding LARP4A and LARP4B and conclude that their complex roles in tumorigenesis are cell-, tissue- and context-dependent, warning that caution must be exercised before categorising either protein as an oncoprotein or tumour-suppressor. We also reveal that LARP4A and LARP4B have often been confused with one another, adding uncertainty in delineating their functions. We suggest that further functional and mechanistic studies of LARP4 proteins present significant challenges for future investigations to recognise the vital contributions of these RBPs in cancer research.

OBJECTIVE: Although there is mounting evidence that massed treatment for PTSD is both feasible and effective, many questions remain about the optimal length of intensive treatment programs (ITPs), as well as the role of adjunctive services, such as psychoeducation, mindfulness, and yoga. Our setting recently transitioned from a three-week ITP to a two-week program. Adjunctive services were reduced, but the amount of individual CPT between programs remained similar. The present study examined the effectiveness of a two-week ITP based on twice daily individual CPT sessions and evaluated the program's noninferiority to an established three-week ITP using a Bayesian analytical approach. METHOD: Bayesian linear mixed regression models were used to explore PTSD and depression changes over time, as well as predictors of change. Noninferiority of the two-week ITP to a three-week ITP was also established using a Bayes factor approach. RESULTS: Results indicate that program participants change meaningfully in both PTSD and depression severity over the course of treatment, and that changes in posttraumatic cognitions predict subsequent changes in these outcomes. Further, the two-week ITP can be considered noninferior to the three-week ITP in both clinical outcomes and overall satisfaction. CONCLUSIONS: In the context of intensive PTSD treatment, the content of the ITP appears to matter more than its overall length. Shorter programs have the potential to increase access and treatment capacity. Our findings demonstrate the importance of continuous and rigorous program evaluation. Limitations as well as future directions for research, such as identifying the most effective treatment components, are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Successfully replacing damaged cartilage with tissue-engineered constructs requires integration with the host tissue and could benefit from leveraging the native tissue's intrinsic healing capacity; however, efforts are limited by a poor understanding of how cartilage repairs minor defects. Here, we investigated the conditions that foster natural cartilage tissue repair to identify strategies that might be exploited to enhance the integration of engineered/grafted cartilage with host tissue. We damaged porcine articular cartilage explants and using a combination of pulsed SILAC-based proteomics, ultrastructural imaging, and catabolic enzyme blocking strategies reveal that integration of damaged cartilage surfaces is not driven by neo-matrix synthesis, but rather local depletion of proteoglycans. ADAMTS4 expression and activity are upregulated in injured cartilage explants, but integration could be reduced by inhibiting metalloproteinase activity with TIMP3. These observations suggest that catabolic enzyme-mediated proteoglycan depletion likely allows existing collagen fibrils to undergo cross-linking, fibrillogenesis, or entanglement, driving integration. Catabolic enzymes are often considered pathophysiological markers of osteoarthritis. Our findings suggest that damage-induced upregulation of metalloproteinase activity may be a part of a healing response that tips towards tissue destruction under pathological conditions and in osteoarthritis, but could also be harnessed in tissue engineering strategies to mediate repair. STATEMENT OF SIGNIFICANCE: Cartilage tissue engineering strategies require graft integration with the surrounding tissue; however, how the native tissue repairs minor injuries is poorly understood. We applied pulsed SILAC-based proteomics, ultrastructural imaging, and catabolic enzyme blocking strategies to a porcine cartilage explant model and found that integration of damaged cartilage surfaces is driven by catabolic enzyme-mediated local depletion of proteoglycans. Although catabolic enzymes have been implicated in cartilage destruction in osteoarthritis, our findings suggest that damage-induced upregulation of metalloproteinase activity may be a part of a healing response that tips towards tissue destruction under pathological conditions. They also suggest that this natural cartilage tissue repair process could be harnessed in tissue engineering strategies to enhance the integration of engineered cartilage with host tissue.

Intensive treatment programs (ITPs) are successful at reducing posttraumatic stress disorder (PTSD) and depression symptoms in veterans. However, the role of the working alliance in the context of ITPs is largely unexplored. The purpose of this study was to examine veteran-rated working alliance with their individual cognitive processing therapy (CPT) provider as a predictor of changes in PTSD and depression symptoms as well as negative posttrauma cognitions in two unique ITP formats. Data were collected from 128 veterans who completed a 2-week ITP, involving 2 × individual CPT/day, as well as 73 veterans who completed a 3-week ITP, involving 1 × group CPT/day and 1 × individual CPT/day. Both ITPs included adjunctive wellness, skills, and psychoeducation services in addition to CPT. Linear mixed-effects models were used to determine whether changes in working alliance predicted changes in PTSD and depression symptoms. Stronger veteran-reported working alliance with their individual CPT therapist, most notably agreement on tasks, predicted significant reductions in both the 2-week and 3-week programs in PTSD (ps = .012 and .002, respectively) and depression symptoms (ps = .009 and .007, respectively) and negative posttrauma cognitions (ps = .009 and .016, respectively). These results highlight the importance of veterans' perceived working alliance with their individual treatment therapists in ITPs. Results suggest that a strong working alliance that is meaningful for treatment outcomes can be developed quickly despite the brevity of this intensive treatment format. Future research should examine ways to facilitate the development of a strong working alliance prior to or as early as possible in ITPs. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMEN El comportamiento alimentario está intrínsecamente asociado al estado afectivo y las emociones dominantes. Esta investigación se propuso analizar la asociación entre afectividad, sintomatología ansiosa y depresiva, regulación emocional, estilos de alimentación desadaptativos: alimentación restrictiva, emocional y externa, y alimentación intuitiva. Se realizó un estudio transversal, de tipo correlacional, en el que participaron 648 adultos de ambos sexos, residentes en Chile. Se recogieron datos de las siguientes variables e instrumentos: afecto dominante con el Positive Affect and Negative Affect Schedule (PANAS); síntomas de depresión y ansiedad con dos preguntas de respuesta cerrada, dificultades de regulación emocional, con Difficulties in Emotion Regulation Scale (DERS); estilos de alimentación con el Dutch Eating Behaviour Questionnaire (DEBQ) y alimentación intuitiva con la Intuitive Eating Scale (IES-2). Se realizaron análisis de correlación y regresión lineal multivariada. Ser mujer y presencia de afecto negativo predijeron los estilos de alimentación desadaptativo emocional y restrictivo. El afecto positivo se asoció a un estilo de alimentación externo. Los tres estilos de alimentación desadaptativos evaluados se asociaron a dificultades de regulación emocional. Por el contrario, la alimentación intuitiva se asoció a ser hombre, afectividad positiva y ausencia de dificultades de regulación emocional. Se confirma la asociación entre la experiencia emocional y los estilos de alimentación y se enfatiza el rol de la regulación emocional como recurso psicológico relevante para prevenir el potencial efecto disfuncional de las emociones en el comportamiento alimentario.
ABSTRACT Eating behavior is intrinsically associated with the affective state and dominant emotions. This research set out to analyze the association between affectivity, anxious and depressive symptoms, emotional regulation, maladaptive eating styles, and intuitive eating. A cross-sectional, correlational study was carried out. Participants were 648 adults of both sexes, residents of Chile. Data were collected on the following variables and instruments: dominant affect with the Positive Affect and Negative Affect Schedule (PANAS); emotional regulation difficulties, with Difficulties in Emotion Regulation Scale (DERS); eating styles with the Dutch Eating Behavior Questionnaire (DEBQ) and intuitive eating with the Intuitive Eating Scale (IES-2). Correlation analysis and multivariate linear regression were performed. Being a woman and the presence of negative affect predicted emotional and restrictive eating styles. Positive affect was associated with an external eating style. The three maladaptive eating styles evaluated were associated with emotional regulation difficulties. On the contrary, intuitive eating was associated with being a man, positive affectivity, and the absence of emotional regulation difficulties. The association between emotional experience and eating styles was confirmed emphasizing the role of emotional regulation as a relevant psychological resource to prevent the potential dysfunctional effect of emotions on eating behavior.
RESUMO
ABSTRACT: The nursing workforce is not keeping pace with the racial demographics in the United States. In addition, attrition rates for ethnic minorities in schools of nursing remain high. This qualitative study examined African American students' perceptions of factors that affect successful completion of nursing school. Five themes emerged: being invisible, sense of isolation, proving myself, focus on school as protective, and being misunderstood. Findings suggest that attention to identified influencing factors may affect minority student graduation success, increasing the likelihood of a diverse nursing workforce.

OBJECTIVE: Evidence-based treatments for posttraumatic stress disorder (PTSD) can be effectively delivered over telehealth. There are, however, no studies that examine the effectiveness of delivering evidence-based treatments for PTSD in an intensive format via telehealth. Telehealth may be well-suited as a delivery modality because it may address barriers specific to intensive treatments. METHOD: To address this gap, we report on a case series of ten consecutively enrolled veterans (60% male; mean age 42.3, SD = 6.3) who participated in a virtual 2-week, cognitive processing therapy (CPT)-based intensive program. RESULTS: All (100%) participants completed treatment and reported large reductions in PTSD and depression symptoms pre- to posttreatment (Hedge's gws = 2.83 and gws = 1.97, respectively), pre- to 3-month follow-up (Hedge's gws = .99 and gws = 1.24, respectively), as well as very high satisfaction. CONCLUSIONS: Results of this case series suggest that evidence-based treatments for PTSD can be effectively delivered in intensive formats over telehealth and lay the foundation for more rigorously designed and larger scale research comparing virtual to in-person delivered intensive PTSD treatments.

Of the many vulnerable groups affected by the spread of COVID-19, veterans have been especially impacted by the pandemic. Beginning in March 2020, nationwide shelter-in-place orders rapidly led to widespread job loss and economic upheaval; disruption and breakdown of multiple support systems; and increases in family stress, all of which may exacerbate underlying PTSD symptoms. Although telehealth has proven an effective means of delivering evidence-based psychotherapies for PTSD, little is known about the delivery of these treatments in an intensive, daily format over telehealth. There is growing need for intensive treatment options to reduce treatment-interfering barriers such as high dropout rates. In order to address this gap in the literature, this paper details several design considerations as well as patient selection procedures for a 2-week virtual intensive treatment program (vITP) for veterans with posttraumatic stress disorder (PTSD), consisting of daily individual Cognitive Processing Therapy (CPT) and other adjunctive interventions. We also describe two cases of veterans who successfully completed the vITP including their clinical outcomes, therapist reflections on the process, feedback regarding the program, as well as challenges patients encountered with the telehealth platform. Intensive evidence-based psychotherapy for PTSD delivered through a virtual format seems to show promise, but more systemic research is needed.
RESUMO
Determination of treatment response to immunotherapy in glioblastoma multiforme (GBM) is a process which can take months. Detection of CD8+ T cell recruitment to the tumor with a noninvasive imaging modality such as positron emission tomography (PET) may allow for tumor characterization and early evaluation of therapeutic response to immunotherapy. In this study, we utilized 89Zr-labeled anti-CD8 cys-diabody-PET to provide proof-of-concept to detect CD8+ T cell immune response to oncolytic herpes simplex virus (oHSV) M002 immunotherapy in a syngeneic GBM model. Immunocompetent mice (n = 16) were implanted intracranially with GSC005 GBM tumors, and treated with intratumoral injection of oHSV M002 or saline control. An additional non-tumor bearing cohort (n = 4) receiving oHSV M002 treatment was also evaluated. Mice were injected with 89Zr-labeled anti-CD8 cys-diabody seven days post oHSV administration and imaged with a preclinical PET scanner. Standardized uptake value (SUV) was quantified. Ex vivo tissue analyses included autoradiography and immunohistochemistry. PET imaging showed significantly higher SUV in tumors which had been treated with M002 compared to those without M002 treatment (p = 0.0207) and the non-tumor bearing M002 treated group (p = 0.0021). Accumulation in target areas, especially the spleen, was significantly reduced by blocking with the non-labeled diabody (p < 0.001). Radioactive probe accumulation in brains was consistent with CD8+ cell trafficking patterns after oHSV treatment. This PET imaging strategy could aid in distinguishing responders from non-responders during immunotherapy of GBM.

AIMS: To retrospectively assess factors associated with John Cunningham virus (JCV) seroconversion in natalizumab-treated patients. BACKGROUND: Natalizumab is highly effective for the treatment of relapsing-remitting multiple sclerosis (RRMS), but its use is complicated by opportunistic JCV infection. This virus can result in progressive multifocal leukoencephalopathy (PML). Serial assessment of JCV serostatus is mandated during natalizumab treatment. METHODS: Patients treated with natalizumab for RRMS at six tertiary hospitals in Melbourne, Australia (n = 865) and 11 MS treatment centres in Brazil (n = 136) were assessed for change in JCV serostatus, duration of exposure to natalizumab and prior immunosuppression. Sensitivity analyses examined whether sex, age, tertiary centre, prior immunosuppression or number of JCV tests affected time to seroconversion. RESULTS: From a cohort of 1001 natalizumab-treated patients, durable positive seroconversion was observed in 83 of 345 initially JCV negative patients (24.1%; 7.3% per year). Conversely, 16 of 165 initially JCV positive patients experienced durable negative seroconversion (9.7%; 3.8% per year). Forty patients (3.9%) had fluctuating serostatus. Time-to-event analysis did not identify a relationship between JCV seroconversion and duration of natalizumab exposure. Prior exposure to immunosuppression was not associated with an increased hazard of positive JCV seroconversion. Male sex was associated with increased JCV seroconversion risk [adjusted hazard ratio 2.09 (95% confidence interval 1.17-3.71) p = 0.012]. CONCLUSION: In this large international cohort of natalizumab-treated patients we observed an annual durable positive seroconversion rate of 7.3%. This rate exceeds that noted in registration and post-marketing studies for natalizumab. This rate also greatly exceeds that predicted by epidemiological studies of JCV seroconversion in healthy populations. Taken together, our findings support emerging evidence that natalizumab causes off-target immune changes that may be trophic for JCV seroconversion. In addition, male sex may be associated with increased positive JCV seroconversion.
RESUMO
OBJECTIVE: To quantify the risk that transcutaneous bilirubin (TcB) screening would fail to recommend phototherapy for a neonate who would have qualified for it if total serum bilirubin (TSB) screening were used. STUDY DESIGN: We conducted a quality improvement project where simultaneous TcB and TSB were obtained on neonates ≥35 weeks of gestation during birth hospitalizations in our hospital system. Using our Utah bilirubin management algorithm, we quantified the risk that TcB screening would fail to identify the need for a confirmatory TSB when TSB screening alone would have revealed that phototherapy was indicated. RESULTS: In 3 hospitals, we obtained 727 paired TcB/TSB measurements. Two instances utilized a blood gas radiometer for TSB, and 725 utilized the clinical laboratory-based TSB method. One of the 727 instances had a TcB indicating NO PHOTOTHERAPY, when the simultaneous TSB indicated PHOTOTHERAPY NEEDED. The TSB from that instance was 1 of the 2 from the blood gas radiometer. We estimate the risk of such an error occurring is 1.4 per 1000 TcB measurements (95% CI 0.03-7.6 per 1000). When only the laboratory TSB is used, we estimate the risk of such an error occurring to be 0 per 1000 TcB measurements (95% CI 0.0-5.1 per 1000). CONCLUSIONS: Using TcB for screening at the birth hospital can identify those qualifying for phototherapy, using the Utah guidelines, with 1 of 727 neonates with a blood gas bilirubin and none of 725 with a laboratory-based analysis misidentified as not needing phototherapy when by TSB they did.

BACKGROUND: Transgender medicine is an emergent subfield with clearly identified educational gaps. AIMS: This manuscript evaluates a gender-affirming healthcare curriculum for second-year medical (M2) students. METHODS: Students received a survey assessing Gender Identity Competency in terms of skills, knowledge and attitudes regarding transgender and gender non-conforming (TGNC) issues. The authors administered the survey before and after the delivery of the curriculum. The curriculum included five online modules, a quiz, a 3-hour case-based workshop and a 2-hour interactive patient-provider panel. RESULTS: Approximately 60% of M2 students (n=77) completed both preassessments and postassessments. The following showed a statistically significant improvement from preassessment to postassessment: student Gender Identity Competency, t(76) = -11.07, p<0.001; skills, t(76) = -15.22, p<0.001; and self-reported knowledge, t(76) = -4.36, p<0.001. Negative attitudes did not differ (p=0.378). Interest in TGNC issues beyond healthcare settings did not change (p=0.334). M2 students reported a significant change in experience role-playing chosen pronouns in a clinical setting, t(76) = -8.95, p<0.001. CONCLUSIONS: The curriculum improved students' gender-affirming medical competency, knowledge and skills. The development of a sustained, longitudinal curriculum is recommended in addition to the continuing education of faculty to reinforce this expanding knowledge and skills base and to address discomfort working with this population.

BACKGROUND: Epidemiologic data in professional sport is becoming an increasingly valuable tool in identifying frequently occurring injuries and developing strategies to reduce their occurrence. Currently, there is a paucity of literature on the epidemiology of knee injuries in professional male rugby league players. METHODS: We retrospectively reviewed medical records from a single male professional rugby league team (Newcastle Knights), competing in Australia, and evaluated knee injuries and time to return to play. RESULTS: In total, 89 knee injuries occurred, with an injury incidence of 616.7 injuries per 1000 players. The most frequently occurring knee injuries were medial collateral ligament (416.7 injuries per 1000 players) and chondral/meniscal injuries (416.7 injuries per 1000 players). For all injury types, being tackled was the most common mechanism of injury, and the median time to return to play was 1 day. Anterior cruciate ligament injuries accounted for the longest time to return to play (median 236.0 days). CONCLUSION: Medial collateral ligament and chondral/meniscal injury types were the most frequent injuries; however, anterior cruciate ligament injuries accounted for the most time missed from sport despite being less common. Professional male rugby league players incur similar knee injury types compared to rugby union based upon our study and other similar studies.
RESUMO
Evaluation of testicular biopsies from azoospermic men requires recognition of phases of germ cell maturation as organized architecturally within the seminiferous tubule, as well as distinguishing the inability to generate mature spermatozoa (germ cell aplasia or maturation arrest) from normal spermatogenesis, which may be associated with a reversible obstruction. While traditional fixatives (eg, Bouin solution) provide exquisite nuclear detail and preserve the architectural integrity of the seminiferous tubule, formalin fixation yields biopsies with relatively poor nuclear detail and frequent luminal sloughing of cells, making it difficult to assess sperm maturation. One clone of the anti-DOG1 antibody was recently found to be expressed in late (postspermatogonial) germ cells. We developed a dual stain including DOG1 and SF-1 to mark late germ cells and Sertoli cells, respectively, in both sloughed and intact cells. Consecutive testicular biopsies (N=28) from men with azoospermia were classified by hematoxylin and eosin morphology and stained with a dual SF-1 (Perseus)/DOG1 (Cell Marque) immunohistochemical stain. Histologic patterns included normal spermatogenesis (5 cases), hypospermatogenesis (5 cases), late maturation arrest (2 cases), Sertoli cell only pattern (15 cases), and extensive tubular hyalinization (1 case). Architectural disruption of seminiferous tubules with sloughing of cells into the lumens was noted in all biopsies, at least focally. SF-1 (nuclear) was expressed in sloughed Sertoli cells; DOG1 (cytoplasmic) in sloughed postspermatogonial germ cells (spermatocytes and spermatids). This resulted in two distinct immunophenotypes: SF-1(+)/DOG1(-) sloughed cells in cases with the Sertoli cell only pattern and SF-1(+)/DOG1(+) sloughed cells in all other histologic patterns (normal spermatogenesis, hypospermatogenesis, and maturation arrest). Because the rate of sperm retrieval is lower in men with the Sertoli cell only pattern, this immunohistochemical stain may assist pathologists in the proper interpretation of testicular biopsies, allowing better-informed decision making by patients and clinicians regarding the subsequent use of assisted reproductive technologies.

Posttraumatic stress disorder (PTSD) is a primary mental health concern of veterans. In clinical settings, efforts to improve broad facets beyond symptom amelioration and consideration of moderators of treatment effectiveness in this population are needed for continued improvement in care. General self-efficacy (GSE) has been indicated as a useful treatment target because of its association with positive outcomes such as increased positive health behaviors. Both race and educational attainment represent potential moderators of treatment response that are relevant for a veteran PTSD population. This study aimed to determine whether a PTSD Recovery Group Therapy Program resulted in improvement in GSE and whether racial and educational differences moderated GSE outcomes. Archival data were examined from male veterans (N = 450) receiving mental health services at a Veterans Affairs medical center using multilevel modeling to examine change in GSE over the course of treatment as well as moderation of change in GSE as a function of race and educational attainment. After completion of group therapy, results indicated there was significant improvement in GSE, with significantly different improvement based on education. Higher levels of education were associated with greater increases in GSE after treatment. Improvement in GSE did not differ by participant race. In clinical settings, efforts to increase GSE and attending to moderators such as educational attainment may be useful for improving PTSD treatment approaches.

OBJECTIVE: Posttraumatic stress disorder (PTSD) is one of the most prevalent mental health diagnoses for veterans. Previous research as well as the minority stress model and transgenerational trauma theories, suggest that race may be associated with PTSD, particularly in veterans. The current study examined whether there were racial differences in symptomology in a sample of combat veterans with PTSD (global and symptom cluster-specific). METHODS: Data were collected from male veterans who identified as non-Hispanic Caucasian or non-Hispanic African American (N = 413). Participants completed the Posttraumatic Stress Disorder Checklist- Military version (PCL-M). The PCL-M items were split into four symptom clusters to align with the DSM-5: Re-experiencing, Avoidance, Numbing, and Hyperarousal. It was hypothesized that African American veterans would report more severe global PTSD symptoms and higher levels of hypervigilance. RESULTS: Findings indicated global PTSD symptoms and three of the four symptom clusters did not differ, although the symptom cluster of Re-experiencing was found to be higher for African Americans compared to Caucasians. CONCLUSIONS: It may be helpful for researchers to broaden their methods of assessing PTSD symptomology, such as to examine specific PTSD symptom clusters, especially when assessing differences by race.
