ABSTRACT
The objective of this preregistered study was to gather evidence on training and clinical experiences offered by clinical psychology doctoral programs on the treatment of antagonism-a construct from the personality and psychopathology literature that captures individual differences in aggressiveness, callousness, grandiosity, domineering, and manipulativeness. We surveyed current graduate students (N = 376) in APA-accredited clinical psychology doctoral programs (Mage = 28.4; 83.2% female; 65.2% White) about their experiences in training and treatment of antagonistic patients (ANT-patients) as well as experiences with patients with predominant negative affect (NA; e.g., anxious and depressed). Students reported significantly less training to treat antagonism compared to NA (|ds| = 0.43-2.88), as well as lower rates of direct clinical experience, generally poorer treatment experiences, and stronger countertransference reactions (|ds| = 0.53-1.40). These discrepancies were especially large for adult-focused students compared to child/adolescent-focused students. In fact, adult-focused students reported a mean competency rating of M = 1.71, between the scalar points not competent at all (1) and a little bit competent (2). Overall, these results indicate a lack of training and competence to treat antagonism among current graduate students, especially adult-focused students. We believe the crux of this issue is a field-wide lack of robust empirical work on antagonism treatments (for adults). Moving forward, we implore researchers and funding agencies to help address this substantial gap, which is both an ethical and practical imperative.

ABSTRACT
Sex differences in psychopathology are well-established, with females demonstrating higher rates of internalizing (INT) psychopathology and males demonstrating higher rates of externalizing (EXT) psychopathology. Using two waves of data from the Adolescent Brain Cognitive Development Study (N = 6,778 at each wave), the current study tested whether the relations between sex and psychopathology might be accounted for by structural brain differences. In general, we found robust, relatively consistent relations between sex and structural morphometry across waves. Relatively few morphometric brain variables were significantly related to INT or EXT across waves, however, with very small effect sizes when present. Next, we tested the extent to which each morphometric brain variable could account for the associations of sex with INT and EXT psychopathology. We found a total of 26 brain regions that accounted for significant portions of the associations between sex and psychopathology across both waves (almost all related to EXT), although the effects present were very small. The current evidence suggests that in children aged 9-12, multiple whole-brain and regional brain variables appear to statistically account for small portions of the sex-psychopathology links, especially for externalizing.

BACKGROUND: The Emory Healthcare Veterans Program (EHVP) is a multidisciplinary intensive outpatient treatment program for post-9/11 veterans and service members with invisible wounds, including posttraumatic stress disorder (PTSD), traumatic brain injury (TBI), substance use disorders (SUD), and other anxiety- and depression-related disorders. OBJECTIVE: This article reviews the EHVP. METHODS: The different treatment tracks that provide integrated and comprehensive treatment are highlighted along with a review of the standard, adjunctive, and auxiliary services that complement individualized treatment plans. RESULTS: This review particularly emphasizes the adjunctive neurorehabilitation service offered to veterans and service members with a TBI history and the EVHP data that indicate large reductions in PTSD and depression symptoms across treatment tracks that are maintained across 12 months follow up. Finally, there is a discussion of possible suboptimal treatment response and the pilot programs related to different treatment augmentation strategies being deploying to ensure optimal treatment response for all. CONCLUSION: Published data indicate that the two-week intensive outpatient program is an effective treatment program for a variety of complex presentations of PTSD, TBI, SUD, and other anxiety- and depression-related disorders in veterans and active duty service members.
ABSTRACT
OBJECTIVE: We sought to factor analyze a broad array of aggression measures to identify a comprehensive, coherent factor structure for this construct. BACKGROUND: Measures and models of trait aggression have multiplied to the point of incoherence. METHOD: In Study 1, a diverse sample of 922 undergraduates completed a battery of items acquired from 42 self-report aggression questionnaires. In Study 2, we administered a curated item pool to another diverse sample of 1447 undergraduates, alongside criterion measures. RESULTS: We curated an initial item pool of 734 items down to 289 items that exhibited sufficient variability, were not redundant with other items, and possessed strong loadings onto a central 'trait aggression' factor. These remaining items were best characterized by a six-factor structure, which captured relational, angry, violent, retaliatory, intimate partner, and alcohol forms of aggression. We estimated their hierarchical structure, correlations with their original aggression scales, Five Factor Model trait dimensions, impulsivity facets, and found them to be robust to gender composition and the inclusion of alcohol-naive and intimate-partner-naive participants. CONCLUSIONS: This factor structure mostly supported widely-accepted models of aggressive personality that focus on its overt and relational forms and reactive functions, though proactive aggression only loosely emerged as a distinct entity. We retained the final items as the Comprehensive Aggression Scale (CAS).
ABSTRACT
We surveyed N = 84 mental health care providers (i.e., psychiatrists, psychologists, social workers) working across two Veterans Affairs health care sites about their experiences working with Veteran patients with antagonism-based clinical presentations (e.g., callous, aggressive, grandiose features), as well as negative affect-based clinical presentations (e.g., depressive, anxious, self-conscious features). Providers reported on aspects of these clinical interactions, including assessments and interventions used, treatment outcomes, interpersonal experiences, and training and preparedness to treat this type of presentation in the future. Compared to treatment experiences with patients with predominant negative affect, providers reported that treatment experiences with antagonistic (ANT) patients tended to be shorter (d = -.60), less effective at improving psychological functioning (d = -.61), more emotionally draining (d = 1.03), and more often marked by relationship ruptures (instance of ≥1 rupture = 72.6% vs. 15.5%). Providers also reported less professional training to treat antagonism (d = -1.56) and less preparedness to treat ANT patients in the future (d = -1.81). These results highlight the important role of patient characteristics in providers' experiences and underscore the need for more training and resources to support mental health providers working with ANT patients.

ABSTRACT
While the neuroanatomical correlates of impulsivity in youths have been examined, there is little research on whether those correlates are consistent across childhood/adolescence. The current study uses data from the age 11/12 (N = 7,083) visit of the Adolescent Brain Cognitive Development Study to investigate the replicability of previous work (Owens et al., 2020) the neuroanatomical correlates of impulsive personality traits identified at age 9/10. Neuroanatomy was measured using structural and diffusion magnetic resonance imaging, and impulsive personality was measured using the UPPS-P Impulsive Behavior Scale. Replicability was quantified using three Open Science Collaboration replication criteria, intraclass correlations, and elastic net regression modeling to make predictions across timepoints. Replicability was highly variable among traits: The neuroanatomical correlates of positive urgency showed substantial similarity between ages 9/10 and 11/12, negative urgency and sensation seeking showed moderate similarity across ages, and (lack of) premeditation and perseverance showed substantial dissimilarity across ages. In all cases, effect sizes between impulsive traits and brain variables were small. These findings suggest that, even for studies with large sample sizes and the same participant pool, the replicability of brain-behavior correlations across a 2-year period cannot be assumed. This may be due to developmental changes across the two timepoints or false-positive/false-negative results at one or both timepoints. These results also highlight an array of neuroanatomical structures that may be important to impulsive personality traits across development from childhood into adolescence.

According to sociocognitive theories, aggression is learned and elicited through a series of cognitive processes, such as expectancies, or the various consequences that an individual considers more or less likely following aggressive behavior. The current manuscript describes a measurement development project that ultimately yielded a 16-item measure of positive and negative aggression expectancies suitable for use in adult populations. Across two content generation surveys, two preliminary item refinement studies, and three full studies, we took an iterative approach and administered large item pools to several samples and refined item content through a combination of empirical (i.e., factor loadings, model fit) and conceptual (i.e., content breadth, non-redundancy) considerations. The Aggression Expectancy Questionnaire displays a four-factor structure, as well as evidence of convergent and divergent validity with self-reported aggression and relevant basic (e.g., antagonism, anger) and complex (e.g., psychopathy) personality variables. It is posited that this type of cognitive mechanism may serve as an intermediary link between distal characterological predictors of aggression and its proximal manifestation, which is in line with several prominent theories of personality and may ultimately hold clinical utility by providing a framework for aggression interventions.

Posttraumatic stress disorder (PTSD) is linked to negative relationship outcomes, but the relational processes that link specific PTSD symptoms to these outcomes over granular periods are not well understood. The current study used a daily diary methodology to investigate the associations between specific PTSD symptoms (i.e., anger, avoidance, reexperiencing, hyperarousal, and numbing) and proximal indices of relationship functioning (i.e., accommodation behaviors, disclosure, intimacy). Participants were members of 64 couples, each comprising a male service member (SM) and female romantic partner (RP), who completed daily assessments of PTSD symptoms and indices of relationship functioning for 2 weeks. The results suggest a somewhat unique role of anger on relationship dynamics: Although mean levels of PTSD symptom clusters were associated with negative relationship outcomes at the bivariate level, daily fluctuations in anger were uniquely related to accommodation behaviors and SM- and RP-reported intimacy in multilevel models, Bs = -0.08-0.50). These findings highlight the importance of considering the differential role of specific PTSD symptoms, like anger, in dyadic interventions for PTSD; several strategies for doing so in the context of contemporary evidence-based treatments are discussed.

INTRODUCTION: Males and females tend to exhibit small but reliable differences in personality traits and indices of psychopathology that are relatively stable over time and across cultures. Previous work suggests that sex differences in brain structure account for differences in domains of cognition. METHODS: We used data from the Human Connectome Project (N = 1098) to test whether sex differences in brain morphometry account for observed differences in the personality traits neuroticism and agreeableness, as well as symptoms of internalizing and externalizing psychopathology. We operationalized brain morphometry in three ways: omnibus measures (e.g., total gray matter volume), Glasser regions defined through a multi-modal parcellation approach, and Desikan regions defined by structural features of the brain. RESULTS: Most expected sex differences in personality, psychopathology, and brain morphometry were observed, but the statistical mediation analyses were null: sex differences in brain morphometry did not account for sex differences in personality or psychopathology. CONCLUSIONS: Men and women tend to exhibit meaningful differences in personality and psychopathology, as well as in omnibus morphometry and regional morphometric differences as defined by the Glasser and Desikan atlases, but these morphometric differences appear unrelated to the psychological differences.

Recent personality neuroscience research in large samples suggests that personality traits tend to bear null-to-small relations to morphometric (i.e., brain structure) regions of interest (ROIs). In this preregistered, two-part study using Human Connectome Project data (N = 1,105), we address the possibility that these null-to-small relations are due, in part, to the "level" (i.e., hierarchical placement) of personality and/or morphometry examined. We used a Five-Factor Model framework and operationalized personality in terms of meta-traits, domains, facets, and items; we operationalized morphometry in terms of omnibus measures (e.g., total brain volume), and cortical thickness and area in the ROIs of the Desikan and Destrieux atlases. First, we compared the patterns of effect sizes observed between these levels using mixed effects modeling. Second, we used a machine learning framework for estimating out-of-sample predictability. Results highlight that personality-morphometry relations are generally null-to-small no matter how they are operationalized. Relatively, the largest mean effect sizes were observed at the domain level of personality, but the largest individual effect sizes were observed at the facet and item level, particularly for the Ideas facet of Openness and its constituent items. The largest effect sizes observed were at the omnibus level of morphometry, and predictive models containing only omnibus variables were comparably predictive to models including both omnibus variable and ROIs. We conclude by encouraging researchers to search across levels of analysis when investigating relations between personality and morphometry and consider prioritizing omnibus measures, which appear to yield the largest and most consistent effects.

Recent reviews suggest that, like much of the psychological literature, research studies using laboratory aggression paradigms tend to be underpowered to reliably locate commonly observed effect sizes (e.g., r = ~.10-.20, Cohen's d = ~0.20-0.40). In an effort to counter this trend, we provide a "power primer" that laboratory aggression researchers can use as a resource when planning studies using this methodology. Using simulation-based power analyses and effect size estimates derived from recent literature reviews, we provide sample size recommendations based on type of research question (e.g., main effect vs. two-way vs. three-way interactions) and correlations among predictors. Results highlight the large number of participants that must be recruited to reach acceptable (~80%) power, especially for tests of interactions where the recommended sample sizes far exceed those typically employed in this literature. These discrepancies are so substantial that we urge laboratory aggression researchers to consider a moratorium on tests of three-way interactions. Although our results use estimates from the laboratory aggression literature, we believe they are generalizable to other lines of research using behavioral tasks, as well as psychological science more broadly. We close by offering a series of best practice recommendations and reiterating long-standing calls for attention to statistical power as a basic element of study planning.

Effect sizes are commonly interpreted using heuristics established by Cohen (e.g., small: r = .1, medium r = .3, large r = .5), despite mounting evidence that these guidelines are mis-calibrated to the effects typically found in psychological research. This study's aims were to 1) describe the distribution of effect sizes across multiple instruments, 2) consider factors qualifying the effect size distribution, and 3) identify examples as benchmarks for various effect sizes. For aim one, effect size distributions were illustrated from a large, diverse sample of 9/10-year-old children. This was done by conducting Pearson's correlations among 161 variables representing constructs from all questionnaires and tasks from the Adolescent Brain and Cognitive Development Study® baseline data. To achieve aim two, factors qualifying this distribution were tested by comparing the distributions of effect size among various modifications of the aim one analyses. These modified analytic strategies included comparisons of effect size distributions for different types of variables, for analyses using statistical thresholds, and for analyses using several covariate strategies. In aim one analyses, the median in-sample effect size was .03, and values at the first and third quartiles were .01 and .07. In aim two analyses, effects were smaller for associations across instruments, content domains, and reporters, as well as when covarying for sociodemographic factors. Effect sizes were larger when thresholding for statistical significance. In analyses intended to mimic conditions used in "real-world" analysis of ABCD data, the median in-sample effect size was .05, and values at the first and third quartiles were .03 and .09. To achieve aim three, examples for varying effect sizes are reported from the ABCD dataset as benchmarks for future work in the dataset. In summary, this report finds that empirically determined effect sizes from a notably large dataset are smaller than would be expected based on existing heuristics.

Recently developed quantitative models of psychopathology (i.e., Hierarchical Taxonomy of Psychopathology) identify an Antagonistic Externalizing spectrum that captures the psychological disposition toward criminal and antisocial behavior. The purpose of the present study was to examine relations between Antagonistic psychopathology (and associated Five-Factor model Antagonism/Agreeableness) and neural functioning related to social-cognitive Theory of Mind using a large sample (N = 973) collected as part of the Human Connectome Project (Van Essen et al., 2013a). No meaningful relations between Antagonism/Antagonistic Externalizing and Theory of Mind-related neural activity or synchrony were observed (p < .005). We conclude by outlining methodological considerations (e.g., validity of social cognition task and low test-retest reliability of functional biomarkers) that may account for these null results, and present recommendations for future research.
ABSTRACT
Posttraumatic stress disorder (PTSD) has a specified precipitant (i.e., trauma), and thus, is particularly well-suited to examine risk and maintenance factors for the development of the disorder. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alternative model of personality disorder (AMPD) is based, in part, on a dimensional trait model; previous research suggests that personality traits are related to PTSD symptoms. To date, there is little research examining this model with regard to PTSD symptoms, and such research could elucidate new strategies for identification and prevention. The present study investigates associations between AMPD traits and PTSD symptoms in a cross-sectional high-risk sample (N = 490; 100% female; 97.8% African American) and in a prospective, longitudinal sample of Level 1 trauma center patients (N = 185; 46.8% female; 72.5% African American). The Personality Inventory for DSM-5 Brief Form domains were significantly associated with PTSD total symptom severity and symptom clusters across both self-report and clinical interview measures. Personality Inventory for DSM-5 Negative Affectivity and Psychoticism emerged as significant predictors of concurrent PTSD. When prospectively predicting PTSD symptoms in the longitudinal cohort, Negative Affectivity and Psychoticism were significant predictors of PTSD symptom severity. These findings indicate how the DSM-5 AMPD pathological traits are associated with risk for stress-related disorders cross-sectionally and prospectively.

Despite a consistent body of work documenting associations between racial discrimination and negative mental health outcomes, the utility and validity of these findings have recently been questioned as some posit that personality traits may account for these associations. To test this hypothesis in a community sample of African Americans (n=419, xÌ age=43.96), we used bivariate relations and hierarchical regression analyses to determine whether racial discrimination accounted for additional variance in depression, anxiety, and posttraumatic stress symptoms beyond the role of personality. Bivariate relations between personality traits and racial discrimination were small and positive (i.e.,rs = ~.10). Regression results demonstrated that racial discrimination accounted for variance in depression, anxiety and posttraumatic stress independent of personality traits (ps<.01). These results suggest that personality traits do not fully explain associations between racial discrimination and negative mental health outcomes, further supporting the detrimental impact of racial discrimination on the mental health of African Americans.
ABSTRACT
Extant literature suggests that men may be less likely than women to engage in prosocial bystander behavior to interrupt sexual and relationship violence. However, there has been little consideration of the influence of masculine gender role discrepancy and masculine discrepancy stress (i.e., stress that occurs when men perceive themselves as falling short of traditional gender norms) on men's bystander beliefs and behaviors. The current study fills an important gap in the literature by assessing the influence of masculine gender role discrepancy and masculine discrepancy stress on a range of prosocial bystander behaviors through their influence on the bystander decision-making process. Participants were 356 undergraduate men recruited from two different Southeastern U.S. universities who completed online surveys assessing self-perceptions of gender role discrepancy, consequent discrepancy stress, bystander decision-making, and bystander behavior in sexual and relationship violence contexts. Path models indicated significant conditional indirect effects of masculine gender role discrepancy on proactive bystander behaviors (i.e., behaviors related to making a plan in advance of being in a risky situation) and bystander behavior in drinking situations across levels of masculine discrepancy stress. Specifically, men who believed that they are less masculine than the typical man reported more pros to intervention in sexual and relationship violence than cons, and thus reported intervening more, but only if they were high in masculine discrepancy stress. Findings suggest that bystander intervention programs should explicitly address and challenge rigid expectations of what it means to be "manly" to transform gender expectations perpetuating sexual and relationship violence.

In the current study, we used a sample of predominantly African-American women with high rates of trauma exposure (N = 434) to examine psychometric properties of the Personality Inventory for DSM-5-Brief Form (PID-5-BF). We compared model fit between a model with five correlated latent factors and a higher-order model in which the five latent factors were used to estimate a single "general pathology" factor. Additionally, we computed estimates of internal consistency and domain interrelations and examined indices of convergent/discriminant validity of the PID-5-BF domains by examining their relations to relevant criterion variables. The expected five-factor structure demonstrated good fit indices in a confirmatory factor analysis, and the more parsimonious, higher-order model was retained. Within this higher-order model, the first-order factors accounted for more variance in the criterion variables than the general pathology factor in most instances. The PID-5-BF domains were highly interrelated (rs = .38 to .66), and convergent/discriminant validity of the domains varied: Negative Affectivity and Detachment generally showed the hypothesized pattern of relations with external criteria, while Antagonism and Disinhibition displayed less consistent and discriminant relations. Results are discussed in terms of the costs and benefits of using brief pathological trait measures in samples characterized by high levels of psychopathology.

The overall reliability or evidentiary value of any body of literature is established in part by ruling out publication bias for any observed effects. Questionable research practices have potentially undermined the evidentiary value of commonly used research paradigms in psychological science. Subsequently, the evidentiary value of these common methodologies remains uncertain. To quantify the severity of these issues in the literature, we selected the Taylor Aggression Paradigm (TAP) as a case study and submitted 170 hypothesis tests spanning over 50 years of research to a preregistered p-curve analysis. The TAP literature (N = 24,685) demonstrated significant evidentiary value but yielded a small average effect size (d = 0.29) and inadequate power (38%). The main effects demonstrated greater evidentiary value, power, and effect sizes than interactions. Studies that tested the effects of measured traits did not differ in evidentiary value or power to those that tested the effects of experimentally manipulated states. Exploratory analyses revealed that evidentiary value, statistical power, and effect sizes have improved over time. We provide recommendations for researchers who seek to maximize the evidentiary value of their psychological measures.

Quantitative models of psychopathology (i.e., HiTOP) propose that personality and psychopathology are intertwined, such that the various processes that characterize personality traits may be useful in describing and predicting manifestations of psychopathology. In the current study, we used data from the Human Connectome Project (N = 1050) to investigate neural activation following receipt of a reward during an fMRI task as one shared mechanism that may be related to the personality trait Extraversion (specifically its sub-component Agentic Extraversion) and internalizing psychopathology. We also conducted exploratory analyses on the links between neural activation following reward receipt and the other Five-Factor Model personality traits, as well as separate analyses by gender. No significant relations (p < .005) were observed between any personality trait or index of psychopathology and neural activation following reward receipt, and most effect sizes were null to very small in nature (i.e., r < |.05|). We conclude by discussing the appropriate interpretation of these null findings, and provide suggestions for future research that spans psychological and neurobiological levels of analysis.
