Targeting Higher-Order Dimensions of Personality in Treatment as a Parsimonious Means to Address Co-Occurring Psychopathology

People with borderline personality disorder (BPD) commonly have co-occurring mental health conditions that may be accounted for by higher-order factors in dimensional models of psychopathology. BPD Compass is a cognitive-behavioral treatment developed to target broad personality domains (i.e., negative affectivity, antagonism, disinhibition) associated with BPD and related conditions. The purpose of the present study was to explore the extent to which BPD Compass can serve as a transdiagnostic intervention for these comorbid conditions. Participants (N = 100; Mage = 28.13, 73.7% female, 79.6% White, 66% sexual minority) were assigned to either immediately begin treatment (randomized and naturalistic) or receive treatment after an 18-week waiting period. At baseline, participants met criteria for an average of 3.28 (SD = 2.02, range: 0-8) comorbid diagnoses ranging in clinical severity from 3.30 (for substance use disorder) to 4.91 (for persistent depressive disorder). Post-treatment clinical severity ratings (CSRs) for those randomized to receive BPD Compass were below clinical thresholds for all assessed conditions except premenstrual dysphoric disorder, whereas post-waitlist CSRs remained above clinical thresholds for all disorders except bipolar II, agoraphobia, and major depressive disorder. Collapsed across all patients who received BPD Compass, pre- to post-treatment improvements in were significant and large in magnitude for most disorders assessed. These results suggest that BPD Compass may be an efficacious transdiagnostic intervention, though our small sample and high rate of dropout warrant further study.

Heroines of Dune (based on the novel by Frank Herbert and the film directed by Denis Villeneuve)

In Dune, Frank Herbert portrayed strong female characters who have a significant impact on the events presented in the novel. The power of femininity is manifested by, for example, members of the influential Bene Gesserit order who are implementing a long-term eugenics plan aimed at creating the Kwisatz Haderach - a man capable of controlling higher-order dimensions. The film, directed by Denis Villeneuve, reinforces the book's feminist message through visuals, dialogues and plot changes. For example, to eliminate the disproportion between the number of women and men in Dune, the director replaced doctor Liet-Kynes, who is a man in the book, with a female character.

The P300 and hierarchical dimensions of psychopathology.

The Hierarchical Taxonomy of Psychopathology (HiTOP) framework offers the potential to better understand how neurobiological mechanisms relate to psychopathology. The P300 is an event-related potential component that indexes attention, stimulus evaluation, and categorization. A blunted P300 has been associated with psychiatric disorders across externalizing, internalizing, and thought disorder domains. However, there has been little research investigating whether the P300 is related to higher-order dimensions of psychopathology. In a sample of 225 adults aged 18-35 years (Mage = 23.09, SD = 3.83, 82.2% female) who were oversampled for psychopathology, the present study examined the associations between the P300 and both psychopathology spectra and a general factor. Participants completed multiple experimental tasks, while electroencephalography was recorded to measure the P300 elicited by auditory, tactile, and visual stimuli. Participants also completed the self-report Comprehensive Assessment of Traits Relevant to Personality Disorder to assess pathological personality dimensions. We used structural equation modeling to examine the relationship between a latent P300 factor and both psychopathology spectra (negative emotionality, detachment, psychoticism, disinhibition, and antagonism) and a general factor. The results indicated that the P300 was inversely related to the general factor. Further analyses revealed no relationships between the P300 and any individual spectrum when accounting for the general factor. Overall, the present study indicates that the P300 is associated with the general factor of psychopathology, which might explain its association with multiple categorical disorders. The study also demonstrates the potential importance of neuroscience-informed dimensional systems to understand clinical phenomena. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Exploring Fractal Quantum Field Theory in Higher-Order Dimensions Using the McGinty Equation

This hypothesis investigates the application of the McGinty Equation to quantum fields in higher-order dimensions, proposing that these fields exhibit self-similar fractal properties. The primary objective is to understand the implications of fractal geometry on quantum field interactions, coupling constants, and particle scattering processes, offering new insights into the fundamental forces and the structure of spacetime.

Pathological personality domains and punishment-enhanced error-related negativity

The error-related negativity (ERN) is an event-related potential that is observed after the commission of an error and is hypothesized to index threat sensitivity. The ERN is associated with multiple psychiatric disorders, but it is unclear if similar results are due to higher-order dimensions of psychopathology. When errors are punished, the ERN is further enhanced, which might better isolate threat sensitivity. However, few studies have examined whether psychopathology is associated with punishment enhancement of the ERN. In a clinical sample of 170 adults, the present study examined the association between pathological personality domains and predictable vs. unpredictable punishment-enhanced ERN. Results indicated that the ERN was enhanced when errors were punished compared to not punished. Greater negative emotionality was associated with a greater predictable punishment-enhanced ERN, while greater disinhibition was associated with smaller predictable punishment-enhanced ERN. The study suggests that higher-order pathological personality domains demonstrate discriminate relationships with punishment-enhanced error-related brain activity.

A detailed hierarchical model of psychopathology in Chinese clinical sample: Based on the SCL-90-R measure

ObjectiveThe Hierarchical Taxonomy of Psychopathology (HiTOP)model is an impressive effort to overcome shortcomings of traditional diagnostic systems. However, almost all of the quantitative empirical evidence used to structure the model comes from Western cultures and is built upon traditional diagnostic categories. This study aims to provide a detailed Chinese version of the HiTOP structure, ranging from symptoms based on The Symptom Checklist 90-R (SCL-90-R) up to the general factor. MethodsWe explored the detailed hierarchical structure of the SCL-90-R scale in adult (N = 34,222) and adolescent (N = 1973) clinical sample from Shanghai Mental Health Center, using extended bass-ackwards approach to draw the HiTOP model. ResultsThe Chinese HiTOP structure had a general factor at the top, 4 higher-order spectra (Internalizing, Externalizing, Broad Thought Disorder and Somatization and Somatic Anxiety) and 6 subfactors (Distress, Somatoform, Hostility, Fear, Psychosis and OCD) across both adult and adolescent samples. In addition, the adult sample contained 2 other subfactors: a) Sleep, and b) Suicide and Guilt. At the symptom level, some items were posited to components diverged from the original SCL-90-R subscales. ConclusionsThese findings offer the first description of the HiTOP structure in two Chinese samples and demonstrate that the SCL-90-R can be used to examine the HiTOP structure. The Somatization spectrum first emerged as a higher-order dimension, suggesting structural differences between Western and Eastern cultures. The results also suggest that transdiagnostic research should (1) further examine the positioning of somatoform symptoms using measures in other Eastern samples, and (2) place more emphasis on interpreting SCL-90-R results across different cultures.

To what extent is the effect of sensory processing sensitivity on distress mediated by resilience? Putting the diathesis-stress model to the test in a sample of gifted adults

The purpose of this prospective study was to examine (a) whether Sensory Processing Sensitivity (SPS) measured at baseline (T0) predicts distress at one year follow-up (T1), and (b) whether and in what way resilience mediates the effect of SPS on distress. The study sample consisted of gifted adults. A total of 738 respondents participated in the study at T0 and T1 (mean age of 44.86; 63.4% female). Structural Equation Modeling and logistic regression analysis were conducted. A high level of SPS at T0 predicted psychological (anxiety and depression) and somatic (physical symptoms and fatigue) distress at T1. As far as indirect effects are concerned, results depended upon whether we looked at the negative or positive higher-order dimension of SPS. A higher score on negative SPS was associated with lower resilience which in turn led to more distress, indicating that low resilience increased the negative impact of negative SPS on distress. In contrast, a higher score on positive SPS was related to more resilience, resulting in less distress, suggesting that in this case resilience had a buffering effect. As resilience is a buffer between SPS and distress, follow-up research could focus on psychological interventions aimed at increasing resilience.

Development and Validation of the SPSQ-26

Abstract: The aim of this article was to develop an abbreviated version of the Sensory Processing Sensitivity Questionnaire (SPSQ), that maintains a similar factorial structure to the original and demonstrates good psychometric properties. The Short Form of the SPSQ (SPSQ-SF) was developed using a split-sample validation design. Items were retained based on impact on internal consistency reliability, fit to the hierarchical structure of the original SPSQ, and information curves based on a Graded Response Model. Subsequently, the dimensionality and fit to the latent structure of the SPSQ were evaluated. Correlations with the original SPSQ, other measures of Sensory Processing Sensitivity, personality, and clinical outcomes were examined. The SPSQ-SF demonstrated a good fit and high correlation with the original SPSQ. Positive correlations were observed with subscales of the Adult Temperament Questionnaire and the Highly Sensitive Person Scale. Neuroticism and Openness showed strong associations with the negative and positive higher-order dimensions of the SPSQ-SF, respectively. The negative higher-order dimension and Emotional and Physiological Reactivity subscale exhibited significant relationships with physical and psychological distress. Thus, the SPSQ-SF demonstrated good convergent, discriminant, and concurrent validity. The SPSQ-SF offers a valid and reliable alternative to the original SPSQ, allowing for the collection of a large amount of information with fewer items.

Exploring and Evaluating the Two-Factor Model of Perfectionism in Sport

Perfectionism is a multidimensional personality trait with two higher-order dimensions; perfectionistic strivings and perfectionistic concerns. The purpose of the present study was to explore and evaluate the two-factor model for the first time using three instruments developed to measure perfectionism in sport. In doing so, we (i) assessed the fit of two-factor models when including and excluding various contentious subscales (other-oriented perfectionism, parental pressure, coach pressure, organisation, and negative reactions to imperfection) and (ii) compared two-factor models to alternative one-factor (or unidimensional) models. Participants were recruited from community and university sports clubs in the UK ( N = 527; M age = 18.07 years, SD = 0.49) and completed the Sport-Multidimensional Perfectionism Scale-2, the Multidimensional Inventory of Perfectionism in Sport, and the Performance Perfectionism Scale-Sport. Support was found for the two-factor model, with superior fit displayed each time the aforementioned subscales were excluded and, in all cases, when compared to a unidimensional model. The findings suggest that the two-factor model is an adequate representation of the underlying structure of instruments designed to measure perfectionism in sport with better fit and conceptual clarity offered by more parsimonious models.

Self-Critical Perfectionism and Anxious and Depressive Symptoms Over 2 Years: Moderated Mediation Models of Anxiety Sensitivity and Experiential Avoidance

This three-wave longitudinal study of 297 community adults (mean age = 38.66 years, 67% female) examined how anxiety sensitivity and experiential avoidance work together to explain the relation between perfectionism and anxious and depressive symptoms over 2 years. Participants completed measures of self-critical (SC) and personal standards (PS) higher-order dimensions of perfectionism, anxiety sensitivity, experiential avoidance, and anxious and depressive symptoms at Time 1. Participants completed measures of anxiety sensitivity, experiential avoidance, and symptoms again at Time 2 one year later, and symptoms measures again at Time 3 two years after baseline. Moderated mediation analyses showed that for those with higher Time 1 experiential avoidance, Time 1 SC perfectionism was indirectly related to Time 3 anxious arousal symptoms through Time 2 anxiety sensitivity. For those with moderate to higher Time 1 anxiety sensitivity, Time 1 SC perfectionism was indirectly associated with Time 3 general distress and anxious arousal symptoms through Time 2 experiential avoidance. These moderated mediation effects were not found for PS perfectionism. These results support anxiety sensitivity and experiential avoidance as moderating and mediating processes that may be important treatment targets for reducing vulnerability to anxious and depressive symptoms over the longer-term in SC perfectionistic individuals.

Measuring the Four Higher-Order Values in Schwartz’s Theory: Validation of a 17-Item Inventory

Schwartz’s theory of basic human values is the dominant framework for assessing values. One of its strengths is that it allows for different levels of analysis. The 10 basic values can be reliably assigned to four higher-order dimensions: Openness to Change, Conservation, Self-Transcendence, and Self-Enhancement. In this paper, we examined the psychometric properties of the Higher-Order-Value Scale-17 (HOVS17), an inventory that economically assesses these higher-order values. We analyzed data from the GESIS Panel, an ongoing large-scale probability-based panel study that fields HOVS17 annually since 2013 and for which HOVS17 was originally developed. We found HOVS17 to have satisfactory psychometric properties. The 17 items were located in the two-dimensional multi-dimensional scaling (MDS) space as hypothesized. All four subscales were unidimensional, showed good fit when modeled as reflective latent variables, and had acceptable reliabilities as well as one-year test–retest stabilities (.65 to .69). The subscales correlated in theoretically plausible ways with a wide range of correlates and criteria, such as personality traits and well-being. This demonstrates that HOVS17 provides a sound basis for studying the development, precursors, and consequences of the higher-order values in the GESIS Panel and in future surveys that adopt HOVS17. We also discuss suggestions for further improvements of the inventory.

Internalizing psychopathology and its links to suicidal ideation, dysfunctional attitudes, and help-seeking readiness in a national sample of college students

BackgroundRecent evidence suggests that multiple emotional disorders may be better assessed using dimensional models of psychopathology. The current study utilized a cross-sectional population survey of college students (N = 8613 participants) to examine the extent to which broad psychopathology factors accounted for specific associations between emotional problems and clinical and behavioral validators: suicidality, dysfunctional attitudes, and treatment seeking. MethodsConfirmatory factor models were estimated to identify the best structure of psychopathology. Models were then estimated to examine the broad and specific associations between each psychopathology indicator and the clinical and behavioral validators. ResultsThe hierarchical model of psychopathology with internalizing problems at the top, fear, and distress at the second level, and five specific symptom dimensions at the third level evidenced the best fit. The associations between symptom indicators of psychopathology and clinical and behavioral validators were relatively small and inconsistent. Instead, much of the association between clinical and behavioral validators and emotional problems operated at a higher-order level. LimitationsThe cross-sectional nature of the survey precludes the ability to make conclusions regarding causality. ConclusionsResearchers should focus on investigating the shared or common components across emotional disorders, particularly concerning individuals presenting with higher rates of suicidal ideation dysfunctional attitudes, and help-seeking behavior. Using higher-order dimensions of psychopathology could simplify the complex presentation of multiple co-occurring disorders and suggest valid constructs for future investigations.

Invariância da Medida de Perfeccionismo entre Estudantes de Graduação Brasileiros e Argentinos

Abstract This study aimed to investigate the cross-cultural invariance of perfectionism between Brazilian and Argentinian cultures, using the Almost Perfect Scale-Revised (APS-R). A series of multi-group exploratory structural equation modeling models were used to test configural, metric, and scalar measurement invariance. The total sample comprised 1589 undergraduate students, 835 Brazilians, and 754 Argentinians, mean age=25.03 (SD=6.58 years). Multi-group analyses revealed that configural and metric measurement invariance were achieved. Partial scalar invariance was found after constraints on the thresholds of items 2 and 10 were released. Minor differences were found in the high standards and order dimensions, although results should be interpreted cautiously due to non-invariance. Overall, the results suggest that the APS-R is mostly comparable between Brazilians and Argentinians. Possible differences in non-invariance specific to some of the scale items, and implications for cross-cultural research of perfectionism are discussed.

DSM-5 self-rated level 1 cross-cutting symptom measure (CCSM1): Proposal for a three-factors model and implications for the assessment of at-risk situations

ObjectiveThe aim of this paper is to study the measurement of the DSM5 self-rated transversal symptoms level 1 (CCSM1) from a dimensional perspective in line with current models of psychopathology in three factors: internalization, thought disorders, externalization. MethodBased on the 670 non-clinical protocols we collected, we verified that the VSS is composed of three factors. We studied the 3-factor composition with half of the sample and confirmed this composition with the other half. To show that these three factors were more relevant than the original 13 dimensions, we compared the results to three clinical groups and, after a cluster analysis, we investigated the intensity and frequency of people at risk across the original dimensions. ResultsWhile the 13 initial dimensions of the CCSM1 do not completely differentiate this sample from the clinical groups, the three high-order dimensions are discriminating. Clustering confirms these results when comparing the least and most affected subjects and allows us to see that these three HODs have significant impacts on the observation of cases at risk of clinical disorders in this non-clinical sample. DiscussionTo be further validated, these three HODs should be studied in relation to tools that assess internalization, thought disorders or externalization.

Progressive Feature Reconstruction and Fusion to Accelerate MRI Imaging: Exploring Insights across Low, Mid, and High-Order Dimensions

Magnetic resonance imaging (MRI) faces ongoing challenges associated with prolonged acquisition times and susceptibility to motion artifacts. Compressed Sensing (CS) principles have emerged as a significant advancement, addressing these issues by subsampling k-space data points and enabling rapid imaging. Nevertheless, the recovery of intricate details from under-sampled data remains a complex endeavor. In this study, we introduce an innovative deep learning approach tailored to the restoration of high-fidelity MRI images from under-sampled k-space data. Our method employs a cascaded reconstruction strategy that progressively restores hierarchical features and fuses them to achieve the final reconstruction. This cascade encompasses low, intermediate, and high orders of reconstruction, which is followed by a return through intermediate and low orders. At distinct reconstruction stages, we introduce a novel reconstruction block to recapture diverse frequency information crucial for image reconstruction. The other core innovation of our proposal lies in a fusion algorithm that harmonizes results from various reconstruction tiers into the final MRI image. Our methodology is validated using two distinct datasets. Notably, our algorithm achieves impressive PSNR values of 32.60 and 31.02 at acceleration factors of 4× and 8× in the FastMRI dataset along with SSIM scores of 0.818 and 0.771, outperforming current state-of-the-art algorithms. Similarly, on the Calgary–Campinas dataset, our algorithm achieves even higher PSNR values, reaching 37.68 and 33.44, which is accompanied by substantial SSIM scores of 0.954 and 0.901. It is essential to highlight that our algorithm achieves these remarkable results with a relatively lower parameter count, underscoring its efficiency. Comparative analyses against analogous methods further emphasize the superior performance of our approach, providing robust evidence of its effectiveness.

Feedback, feedback-on-feedback and re-feedback: effects of written dialogic peer feedback on English as a foreign language writing

Dialogic peer feedback has been recommended and increasingly used in English as a foreign language writing context, yet the specific effects of peer-to-peer written dialogue about feedback remain under-researched. Using a quasi-experimental design, this empirical study investigated the effects of the presence/absence of written dialogue between the peer feedback provider and receiver on students’ provision of feedback, adoption of received feedback, improvements in writing quality, and attitudes towards feedback dialogue across a four-week writing program. The study drew on several data sources including feedback texts, revision texts, a questionnaire survey and monthly reflection journals of forty-one students. Results showed that students involved in the written dialogue demonstrated a generally positive attitude towards it and outperformed those without such a process by generating more accurate adoption, focusing comments to a greater extent on higher-order dimensions of writing (unity, support and coherence), and implementing better revisions. The dialogic process enhanced students’ feedback literacy and engagement by improving their understanding of feedback, their linguistic and subject knowledge, and their agentic clarification and negotiation of revisions.

High-precision mapping reveals the structure of odor coding in the human brain.

Odor perception is inherently subjective. Previous work has shown that odorous molecules evoke distributed activity patterns in olfactory cortices, but how these patterns map on to subjective odor percepts remains unclear. In the present study, we collected neuroimaging responses to 160 odors from 3 individual subjects (18 h per subject) to probe the neural coding scheme underlying idiosyncratic odor perception. We found that activity in the orbitofrontal cortex (OFC) represents the fine-grained perceptual identity of odors over and above coarsely defined percepts, whereas this difference is less pronounced in the piriform cortex (PirC) and amygdala. Furthermore, the implementation of perceptual encoding models enabled us to predict olfactory functional magnetic resonance imaging responses to new odors, revealing that the dimensionality of the encoded perceptual spaces increases from the PirC to the OFC. Whereas encoding of lower-order dimensions generalizes across subjects, encoding of higher-order dimensions is idiosyncratic. These results provide new insights into cortical mechanisms of odor coding and suggest that subjective olfactory percepts reside in the OFC.

Perfectionism and performance in a trail running competition: a prospective study of the interactive effects of perfectionism

ABSTRACT Several studies explored the links between perfectionism and sport performance. However, only a few studies examined this relationship in the context of real sport competition and with a focus on the possible interactive effects of the dimensions of perfectionism. The present study aimed to investigate whether the two higher-order dimensions of perfectionism – perfectionistic strivings and perfectionistic concerns – interact in predicting performance in mountain trail running competitions. 167 athletes (54 females, 113 males) aged 19 to 65 (M = 39.32, SD = 9.35) completed measures of perfectionism in the week prior to the competition. Regression analyses revealed that perfectionistic strivings were a positive predictor of the runners’ performance while perfectionistic concerns showed no significant associations with performance. However, a more in-depth exploration within the framework of the 2 × 2 model of perfectionism showed that the beneficial effects of high perfectionistic strivings are no longer significant when accompanied by high levels of perfectionistic concerns. These results support the notion that perfectionistic concerns may be detrimental to sport performance even if their overall, direct effects are not significant, adding first evidence of the existence of standard but also flipped perfectionistic tipping points in the context of sport performance.

BPD Compass is an accessible alignment of dimensional assessment and treatment.

BPD Compass is a short-term (18-session) intervention for borderline personality disorder (BPD) that was designed to address the higher-order dimensions of personality implicated in this condition in the Alternative Model of Personality Disorders (AMPD): Negative affectivity, Antagonism, and Disinhibition. We received three commentaries on our manuscript describing the conceptual background for BPD Compass; the purpose of this rejoinder is to respond to that feedback. In our rejoinder, we challenge researchers and clinicians to stretch their assumptions about what treatment for BPD should look like, describe the utility of a cognitive-behavioral approach for subsequent dissemination, and discuss how information Criterion A of the AMPD can also be used to personalize course of treatment with BPD Compass.
